According to John Banas and colleagues, the research on laughter in the classroom indicates that a classroom full of laughter increases learning. In contrast, Plato argued that laughter is a vice and chastised those who would give in to it. Nonetheless, between the ancient concept of laughter as vice and the modern concept of laughter as learning…

Laughter is often considered to be the product of humour. However laughter is a social emotion, occurring most often in interactions, where it is associated with bonding, agreement, affection and emotional regulation. Laughter is underpinned by complex neural systems, allowing it to be used flexibly: in humans and chimpanzees, social (voluntary) laughter is distinctly different from evoked (involuntary) laughter, a distinction which is also seen in brain imaging studies of laughter.

The therapeutic value of laughter in medicine.

Mora-Ripoll, Ramon

2010-01-01

The aim of this review is to identify, critically evaluate, and summarize the laughter literature across a number of fields related to medicine and health care to assess to what extent laughter health-related benefits are currently supported by empirical evidence. A comprehensive laughter literature search was performed. A thorough search of the gray literature was also undertaken. A list of inclusion and exclusion criteria was identified. It was necessary to distinguish between humor and laughter to assess health-related outcomes elicited by laughter only. Thematic analysis was applied to summarize laughter health-related outcomes, relationships, and general robustness. Laughter has shown physiological, psychological, social, spiritual, and quality-of-life benefits. Adverse effects are very limited, and laughter is practically lacking in contraindications. Therapeutic efficacy of laughter is mainly derived from spontaneous laughter (triggered by external stimuli or positive emotions) and self-induced laughter (triggered by oneself at will), both occurring with or without humor. The brain is not able to distinguish between these types; therefore, it is assumed that similar benefits may be achieved with one or the other. Although there is not enough data to demonstrate that laughter is an all-around healing agent, this review concludes that there exists sufficient evidence to suggest that laughter has some positive, quantifiable effects on certain aspects of health. In this era of evidence-based medicine, it would be appropriate for laughter to be used as a complementary/alternative medicine in the prevention and treatment of illnesses, although further well-designed research is warranted.

Social Context Disambiguates the Interpretation of Laughter

Despite being a pan-cultural phenomenon, laughter is arguably the least understood behaviour deployed in social interaction. As well as being a response to humour, it has other important functions including promoting social affiliation, developing cooperation and regulating competitive behaviours. This multi-functional feature of laughter marks it as an adaptive behaviour central to facilitating social cohesion. However, it is not clear how laughter achieves this social cohesion. We consider two approaches to understanding how laughter facilitates social cohesion – the ‘representational’ approach and the ‘affect-induction’ approach. The representational approach suggests that laughter conveys information about the expresser’s emotional state, and the listener decodes this information to gain knowledge about the laugher’s felt state. The affect-induction approach views laughter as a tool to influence the affective state of listeners. We describe a modified version of the affect-induction approach, in which laughter is combined with additional factors – including social context, verbal information, other social signals and knowledge of the listener’s emotional state – to influence an interaction partner. This view asserts that laughter by itself is ambiguous: the same laughter may induce positive or negative affect in a listener, with the outcome determined by the combination of these additional factors. Here we describe two experiments exploring which of these approaches accurately describes laughter. Participants judged the genuineness of audio–video recordings of social interactions containing laughter. Unknown to the participants the recordings contained either the original laughter or replacement laughter from a different part of the interaction. When replacement laughter was matched for intensity, genuineness judgements were similar to judgements of the original unmodified recordings. When replacement laughter was not matched for intensity, genuineness judgements were generally significantly lower. These results support the affect-induction view of laughter by suggesting that laughter is inherently underdetermined and ambiguous, and that its interpretation is determined by the context in which it occurs.

[Laughter: gender differences].

PubMed

Mora-Ripoll, R; Ubal-López, R

2011-01-01

Laughter is associated to many physiological and psychological benefits. Although women laugh more than men do, the daily frequency of laughter does not seem to differ. Laughter in all its forms and manifestations is an indicator of family vitality and healthy couples. Laughter is very attractive at the interpersonal level, especially for women. Men use humor much more and laughter when it comes to discussing sensitive health issues. In women, laughter would be more associated with greater social support in relationships and as a tool to cope with stress. Inviting laughter in the doctor's office may be very useful when directing certain messages on therapeutic management. Taking into account possible gender differences in the use of humor and laughter may help to improve the relationship with the patient and optimize the clinical application of laughter in health care and education setting.

Potential health benefits of simulated laughter: a narrative review of the literature and recommendations for future research.

PubMed

Mora-Ripoll, Ramon

2011-06-01

Scientific research has shown that laughter may have both preventive and therapeutic values. Health-related benefits of laughter are mainly reported from spontaneous laughter interventional studies. While the human mind can make a distinction between simulated and spontaneous laughter, the human body cannot. Either way health-related outcomes are deemed to be produced. Simulated laughter is thus a relatively under-researched treatment modality with potential health benefits. The aim of this review was firstly to identify, critically evaluate and summarize the laughter literature; secondly to assess to which extent simulated laughter health-related benefits are currently sustained by empirical evidence; and lastly to provide recommendations and future directions for further research. A comprehensive laughter literature search was performed. A list of inclusion and exclusion criteria was identified. Thematic analysis was applied to summarize laughter health-related outcomes, relationships, and general robustness. Laughter has shown different physiological and psychological benefits. Adverse effects are very limited and laughter is practically lacking in counter-indications. Despite the limited number of publications, there is some evidence to suggest that simulated laughter has also some effects on certain aspects of health, though further well-designed research is warranted. Simulated laughter techniques can be easily implemented in traditional clinical settings for health and patient care. Their effective use for therapeutic purposes needs to be learned, practiced, and developed as any other medical strategy. Practical guidelines and further research are needed to help health care professionals (and others) implement laughter techniques in their health care portfolio. Copyright © 2011 Elsevier Ltd.

Excluded by laughter: laughing until it hurts someone else.

Klages, Stephanie V; Wirth, James H

Can laughter cause social pain? Given the host of ways exclusion is communicated, we examined if exclusive laughter could produce the aversive consequences accordant with social exclusion. Using a validated recall paradigm, participants recounted a time of exclusive or inclusive laughter or a typical Wednesday (control condition). Participants recalling exclusive laughter felt more ostracized, increased social pain. thwarted basic needs, worsened mood, reduced relational evaluation, and increased temptations to aggress compared to inclusive laughter or a typical Wednesday; there were generally no significant differences between the inclusive laughter and a typical Wednesday. Participants recalling exclusive laughter also felt more verbally and emotionally bullied, demonstrating empirically, for one of the first times, a link between social exclusion and bullying.

Laughter as a scientific problem: An adventure in sidewalk neuroscience.

PubMed

Provine, Robert R

2016-06-01

Laughter is a stereotyped, innate, human play vocalization that provides an ideal simple system for neurobehavioral analyses of the sort usually associated with such animal models as walking, wing-flapping, and bird song. Laughter research is in its early stages, where the frontiers are near and accessible to simple observational procedures termed "sidewalk neuroscience." The basic, nontechnical approach of describing the act of laughter and when humans do it has revealed a variety of phenomena of social and neurological significance. Findings include the acoustic structure of laughter, the minimal voluntary control of laughter, contagiousness, the "punctuation effect" that describes the placement of laughter in conversation, the dominance of speech over laughter, the role of breath control in the evolution of speech, the evolutionary trajectory of laughter in primates, and the role of laughter in human matching and mating. If one knows where to look and how to see, advances in neuroscience are accessible to anyone and require minimal resources. © 2015 Wiley Periodicals, Inc.

A comparison of the cardiovascular effects of simulated and spontaneous laughter.

Laughter has long been regarded as beneficial for health, but the mechanisms are not clearly understood. The current study aimed to compare the acute cardiovascular effects of spontaneous and simulated laughter. A mixed factorial experiment was performed to examine changes in cardiovascular variables in response to experimental tasks across conditions. A sample of 72 participants were randomised to one of three 6 min interventions. Participants in the simulated laughter condition were asked to generate fake laughter, the spontaneous laughter condition viewed a humorous video, and the control condition watched a non-humorous documentary. This was followed by a laboratory stress task. Heart rate and heart rate variability (as indexed by rMSSD) were monitored continuously throughout the experiment using ECG. The simulated laughter condition had a significantly higher heart rate (p < .001, η p 2  = .26) and lower rMSSD (p < .001, η p 2  = .13) during the laughter task compared to the other two conditions. Follow-up hierarchical regressions indicated that the difference in heart rate was due to the fact that the simulated condition produced more laughter. The difference in rMSSD, however, was unique to the simulated condition even when controlling for the amount of laughter. The simulated laughter condition had a significantly lower mean HR during the stress task but this was not significant after controlling amount of laughter produced. Laughter leads to increased heart rate and reduced heart rate variability, which is similar to the effects of exercise. This finding is more pronounced in simulated laughter.

Different Types of Laughter Modulate Connectivity within Distinct Parts of the Laughter Perception Network

PubMed Central

Ethofer, Thomas; Brück, Carolin; Alter, Kai; Grodd, Wolfgang; Kreifelts, Benjamin

2013-01-01

Laughter is an ancient signal of social communication among humans and non-human primates. Laughter types with complex social functions (e.g., taunt and joy) presumably evolved from the unequivocal and reflex-like social bonding signal of tickling laughter already present in non-human primates. Here, we investigated the modulations of cerebral connectivity associated with different laughter types as well as the effects of attention shifts between implicit and explicit processing of social information conveyed by laughter using functional magnetic resonance imaging (fMRI). Complex social laughter types and tickling laughter were found to modulate connectivity in two distinguishable but partially overlapping parts of the laughter perception network irrespective of task instructions. Connectivity changes, presumably related to the higher acoustic complexity of tickling laughter, occurred between areas in the prefrontal cortex and the auditory association cortex, potentially reflecting higher demands on acoustic analysis associated with increased information load on auditory attention, working memory, evaluation and response selection processes. In contrast, the higher degree of socio-relational information in complex social laughter types was linked to increases of connectivity between auditory association cortices, the right dorsolateral prefrontal cortex and brain areas associated with mentalizing as well as areas in the visual associative cortex. These modulations might reflect automatic analysis of acoustic features, attention direction to informative aspects of the laughter signal and the retention of those in working memory during evaluation processes. These processes may be associated with visual imagery supporting the formation of inferences on the intentions of our social counterparts. Here, the right dorsolateral precentral cortex appears as a network node potentially linking the functions of auditory and visual associative sensory cortices with those of the mentalizing-associated anterior mediofrontal cortex during the decoding of social information in laughter.

Laughter exaggerates happy and sad faces depending on visual context

2012-01-01

Laughter is an auditory stimulus that powerfully conveys positive emotion. We investigated how laughter influenced visual perception of facial expressions. We simultaneously presented laughter with a happy, neutral, or sad schematic face. The emotional face was briefly presented either alone or among a crowd of neutral faces. We used a matching method to determine how laughter influenced the perceived intensity of happy, neutral, and sad expressions. For a single face, laughter increased the perceived intensity of a happy expression. Surprisingly, for a crowd of faces laughter produced an opposite effect, increasing the perceived intensity of a sad expression in a crowd. A follow-up experiment revealed that this contrast effect may have occurred because laughter made the neutral distracter faces appear slightly happy, thereby making the deviant sad expression stand out in contrast. A control experiment ruled out semantic mediation of the laughter effects. Our demonstration of the strong context dependence of laughter effects on facial expression perception encourages a re-examination of the previously demonstrated effects of prosody, speech content, and mood on face perception, as they may similarly be context dependent.

This study aimed to evaluate the effects of a simulated laughter programme on mood, cortisol levels, and health-related quality of life among haemodialysis patients. Forty participants were randomly assigned to a laughter group (n = 20) or a control group (n = 20). Eleven participants completed the laughter programme after haemodialysis sessions and 18 control participants remained. The 4-week simulated laughter programme included weekly 60 min group sessions of simulated laughter, breathing, stretching exercises, and meditation, as well as daily 15 s individual laughter sessions administered via telephone. Mood, cortisol levels, and health-related quality of life were analysed using the rank analysis of covariance, and Wilcoxon's signed rank test. The laughter group exhibited improvements in mood, symptoms, social interaction quality, and role limitations due to physical health. The simulated laughter programme may help improve mood and health-related quality of life among haemodialysis patients. Copyright © 2016 Elsevier Ltd. All rights reserved.

Differentiation of emotions in laughter at the behavioral level.

2009-06-01

Although laughter is important in human social interaction, its role as a communicative signal is poorly understood. Because laughter is expressed in various emotional contexts, the question arises as to whether different emotions are communicated. In the present study, participants had to appraise 4 types of laughter sounds (joy, tickling, taunting, schadenfreude) either by classifying them according to the underlying emotion or by rating them according to different emotional dimensions. The authors found that emotions in laughter (a) can be classified into different emotional categories, and (b) can have distinctive profiles on W. Wundt's (1905) emotional dimensions. This shows that laughter is a multifaceted social behavior that can adopt various emotional connotations. The findings support the postulated function of laughter in establishing group structure, whereby laughter is used either to include or to exclude individuals from group coherence.

Laughter as an approach to vocal evolution: The bipedal theory.

PubMed

Provine, Robert R

2017-02-01

Laughter is a simple, stereotyped, innate, human play vocalization that is ideal for the study of vocal evolution. The basic approach of describing the act of laughter and when we do it has revealed a variety of phenomena of social, linguistic, and neurological significance. Findings include the acoustic structure of laughter, the minimal voluntary control of laughter, the punctuation effect (which describes the placement of laughter in conversation and indicates the dominance of speech over laughter), and the role of laughter in human matching and mating. Especially notable is the use of laughter to discover why humans can speak and other apes cannot. Quadrupeds, including our primate ancestors, have a 1:1 relation between breathing and stride because their thorax must absorb forelimb impacts during running. The direct link between breathing and locomotion limits vocalizations to short, simple utterances, such as the characteristic panting chimpanzee laugh (one sound per inward or outward breath). The evolution of bipedal locomotion freed the respiration system of its support function during running, permitting greater breath control and the selection for human-type laughter (a parsed exhalation), and subsequently the virtuosic, sustained, expiratory vocalization of speech. This is the basis of the bipedal theory of speech evolution.

Intense or malicious? The decoding of eyebrow-lowering frowning in laughter animations depends on the presentation mode

PubMed Central

Hofmann, Jennifer

2014-01-01

Joyful laughter is the only laughter type that has received sufficient validation in terms of morphology (i.e., face, voice). Still, it is unclear whether joyful laughter involves one prototypical facial-morphological configuration (Duchenne Display and mouth opening) to be decoded as such, or whether qualitatively distinct facial markers occur at different stages of laughter intensity. It was proposed that intense laughter goes along with eyebrow-lowering frowning, but in decoding studies of pictures, these “frowns” were associated with perceived maliciousness rather than higher intensity. Thus, two studies were conducted to investigate the influence of the presentation mode (static, dynamic) and eyebrow-lowering frowning on the perception of laughter animations of different intensity. In Study 1, participants (N = 110) were randomly assigned to two presentation modes (static pictures vs. dynamic videos) to watch animations of Duchenne laughter and laughter with added eyebrow-lowering frowning. Ratings on the intensity, valence, and contagiousness of the laughter were completed. In Study 2, participants (N = 55) saw both animation types in both presentation modes sequentially. Results confirmed that the static presentation lead to eyebrow-lowering frowning in intense laughter being perceived as more malicious, less intense, less benevolent, and less contagious compared to the dynamic presentation. This was replicated for maliciousness in Study 2, although participants could potentially infer the “frown” as a natural element of the laugh, as they had seen the video and the picture. Thus, a dynamic presentation is necessary for detecting graduating intensity markers in the joyfully laughing face. While this study focused on the decoding, future studies should investigate the encoding of frowning in laughter. This is important, as tools assessing facially expressed joy might need to account for laughter intensity markers that differ from the Duchenne Display. PMID:25477836

Laughter and MIRTH (Methodical Investigation of Risibility, Therapeutic and Harmful): narrative synthesis.

Ferner, R E; Aronson, J K

2013-12-12

To review the beneficial and harmful effects of laughter. Narrative synthesis. We searched Medline (1946 to June 2013) and Embase (1974 to June 2013) for reports of benefits or harms from laughter in humans, and counted the number of papers in each category. Benefits of laughter include reduced anger, anxiety, depression, and stress; reduced tension (psychological and cardiovascular); increased pain threshold; reduced risk of myocardial infarction (presumably requiring hearty laughter); improved lung function; increased energy expenditure; and reduced blood glucose concentration. However, laughter is no joke-dangers include syncope, cardiac and oesophageal rupture, and protrusion of abdominal hernias (from side splitting laughter or laughing fit to burst), asthma attacks, interlobular emphysema, cataplexy, headaches, jaw dislocation, and stress incontinence (from laughing like a drain). Infectious laughter can disseminate real infection, which is potentially preventable by laughing up your sleeve. As a side effect of our search for side effects, we also list pathological causes of laughter, among them epilepsy (gelastic seizures), cerebral tumours, Angelman's syndrome, strokes, multiple sclerosis, and amyotrophic lateral sclerosis or motor neuron disease. Laughter is not purely beneficial. The harms it can cause are immediate and dose related, the risks being highest for Homeric (uncontrollable) laughter. The benefit-harm balance is probably favourable. It remains to be seen whether sick jokes make you ill or jokes in bad taste cause dysgeusia, and whether our views on comedians stand up to further scrutiny.

Pathological Laughter as a Symptom of Midbrain Infarction

2004-01-01

Pathological laughter is an uncommon symptom usually caused by bilateral, diffuse cerebral lesions. It has rarely been reported in association with isolated cerebral lesions. Midbrain involvement causing pathological laughter is extremely unusual. We describe three patients who developed pathological laughter after midbrain and pontine-midbrain infarction. In two patients a small infarction in the left paramedian midbrain was detected, whereas the third one sustained a massive bilateral pontine infarction extending to the midbrain. Laughter heralded stroke by one day in one patient and occurred as a delayed phenomenon three months after stroke in another. Pathological laughter ceased within a few days in two patients and was still present at a two year follow-up in the patient with delayed-onset laughter. Pathological laughter can herald midbrain infarction or follow stroke either shortly after onset of symptoms or as a delayed phenomenon. Furthermore, small unilateral midbrain infarctions can cause this rare complication. PMID:15706050

Laughing: a demanding exercise for trunk muscles.

PubMed

Wagner, Heiko; Rehmes, Ulrich; Kohle, Daniel; Puta, Christian

2014-01-01

Social, psychological, and physiological studies have provided evidence indicating that laughter imposes an increased demand on trunk muscles. It was the aim of this study to quantify the activation of trunk muscles during laughter yoga in comparison with crunch and back lifting exercises regarding the mean trunk muscle activity. Muscular activity during laughter yoga exercises was measured by surface electromyography of 5 trunk muscles. The activation level of internal oblique muscle during laughter yoga is higher compared to the traditional exercises. The multifidus, erector spinae, and rectus abdominis muscles were nearly half activated during laughter yoga, while the activation of the external oblique muscle was comparable with the crunch and back lifting exercises. Our results indicate that laughter yoga has a positive effect on trunk muscle activation. Thus, laughter seems to be a good activator of trunk muscles, but further research is required whether laughter yoga is a good exercise to improve neuromuscular recruitment patterns for spine stability.

Social Laughter Triggers Endogenous Opioid Release in Humans.

The size of human social networks significantly exceeds the network that can be maintained by social grooming or touching in other primates. It has been proposed that endogenous opioid release after social laughter would provide a neurochemical pathway supporting long-term relationships in humans (Dunbar, 2012), yet this hypothesis currently lacks direct neurophysiological support. We used PET and the μ-opioid-receptor (MOR)-specific ligand [ 11 C]carfentanil to quantify laughter-induced endogenous opioid release in 12 healthy males. Before the social laughter scan, the subjects watched laughter-inducing comedy clips with their close friends for 30 min. Before the baseline scan, subjects spent 30 min alone in the testing room. Social laughter increased pleasurable sensations and triggered endogenous opioid release in thalamus, caudate nucleus, and anterior insula. In addition, baseline MOR availability in the cingulate and orbitofrontal cortices was associated with the rate of social laughter. In a behavioral control experiment, pain threshold-a proxy of endogenous opioidergic activation-was elevated significantly more in both male and female volunteers after watching laughter-inducing comedy versus non-laughter-inducing drama in groups. Modulation of the opioidergic activity by social laughter may be an important neurochemical pathway that supports the formation, reinforcement, and maintenance of human social bonds. SIGNIFICANCE STATEMENT Social contacts are vital to humans. The size of human social networks significantly exceeds the network that can be maintained by social grooming in other primates. Here, we used PET to show that endogenous opioid release after social laughter may provide a neurochemical mechanism supporting long-term relationships in humans. Participants were scanned twice: after a 30 min social laughter session and after spending 30 min alone in the testing room (baseline). Endogenous opioid release was stronger after laughter versus the baseline scan. Opioid receptor density in the frontal cortex predicted social laughter rates. Modulation of the opioidergic activity by social laughter may be an important neurochemical mechanism reinforcing and maintaining social bonds between humans.

Aping expressions? Chimpanzees produce distinct laugh types when responding to laughter of others.

Humans have the ability to replicate the emotional expressions of others even when they undergo different emotions. Such distinct responses of expressions, especially positive expressions, play a central role in everyday social communication of humans and may give the responding individuals important advantages in cooperation and communication. The present work examined laughter in chimpanzees to test whether nonhuman primates also use their expressions in such distinct ways. The approach was first to examine the form and occurrence of laugh replications (laughter after the laughter of others) and spontaneous laughter of chimpanzees during social play and then to test whether their laugh replications represented laugh-elicited laugh responses (laughter triggered by the laughter of others) by using a quantitative method designed to measure responses in natural social settings. The results of this study indicated that chimpanzees produce laugh-elicited laughter that is distinct in form and occurrence from their spontaneous laughter. These findings provide the first empirical evidence that nonhuman primates have the ability to replicate the expressions of others by producing expressions that differ in their underlying emotions and social implications. The data further showed that the laugh-elicited laugh responses of the subjects were closely linked to play maintenance, suggesting that chimpanzees might gain important cooperative and communicative advantages by responding with laughter to the laughter of their social partners. Notably, some chimpanzee groups of this study responded more with laughter than others, an outcome that provides empirical support of a socialization of expressions in great apes similar to that of humans.

Laughter is a complex motor behavior that, typically, expresses mirth. Despite its fundamental role in social life, knowledge about the neural basis of laughter is very limited and mostly based on a few electrical stimulation (ES) studies carried out in epileptic patients. In these studies laughter was elicited from temporal areas where it was accompanied by mirth and from frontal areas plus an anterior cingulate case where laughter without mirth was observed. On the basis of these findings, it has been proposed a dichotomy between temporal lobe areas processing the emotional content of laughter and anterior cingulate cortex (ACC) and motor areas responsible of laughter production. The present study is aimed to understand the role of ACC in laughter. We report the effects of stimulation of 10 rostral, pregenual ACC (pACC) patients in which the ES elicited laughter. In half of the patients ES elicited a clear burst of laughter with mirth, while in the other half mirth was not evident. This large dataset allow us to offer a more reliable picture of the functional contribute of this region in laughter, and to precisely localize it in the cingulate cortex. We conclude that the pACC is involved in both the motor and the affective components of emotions, and challenge the validity of a sharp dichotomy between motor and emotional centers for laughing. Finally, we suggest a possible anatomical network for the production of positive emotional expressions. Copyright © 2015 Elsevier Ltd. All rights reserved.

Laughter and MIRTH (Methodical Investigation of Risibility, Therapeutic and Harmful): narrative synthesis

Aronson, J K

2013-01-01

Objective To review the beneficial and harmful effects of laughter. Design Narrative synthesis. Data sources and review methods We searched Medline (1946 to June 2013) and Embase (1974 to June 2013) for reports of benefits or harms from laughter in humans, and counted the number of papers in each category. Results Benefits of laughter include reduced anger, anxiety, depression, and stress; reduced tension (psychological and cardiovascular); increased pain threshold; reduced risk of myocardial infarction (presumably requiring hearty laughter); improved lung function; increased energy expenditure; and reduced blood glucose concentration. However, laughter is no joke—dangers include syncope, cardiac and oesophageal rupture, and protrusion of abdominal hernias (from side splitting laughter or laughing fit to burst), asthma attacks, interlobular emphysema, cataplexy, headaches, jaw dislocation, and stress incontinence (from laughing like a drain). Infectious laughter can disseminate real infection, which is potentially preventable by laughing up your sleeve. As a side effect of our search for side effects, we also list pathological causes of laughter, among them epilepsy (gelastic seizures), cerebral tumours, Angelman’s syndrome, strokes, multiple sclerosis, and amyotrophic lateral sclerosis or motor neuron disease. Conclusions Laughter is not purely beneficial. The harms it can cause are immediate and dose related, the risks being highest for Homeric (uncontrollable) laughter. The benefit-harm balance is probably favourable. It remains to be seen whether sick jokes make you ill or jokes in bad taste cause dysgeusia, and whether our views on comedians stand up to further scrutiny. PMID:24336308

We recently treated six patients for OCD utilizing deep brain stimulation (DBS) of the anterior limb of the internal capsule and the nucleus accumbens region (ALIC-NA). We individually tested leads via a scripted intraoperative protocol designed to determine DBS-induced side effects and mood changes. We previously published qualitative data regarding our observations of induced emotional behaviors in our first five subjects. We have now studied these same behaviors in the full cohort of six patients over 2 years of follow-up and have examined the relationship of these behaviors to intraoperative mood changes and postoperative clinical outcomes. Five patients experienced at least one smile response during testing. At higher voltages of stimulation, some of these smiles progressed to natural laughter. Smiles and laughter were associated with mood elevation. At stimulation locations at which smiles were observed, voltage and mood were significantly correlated (p=0.0004 for right brain and p<0.0001 for left brain). In contrast, at contacts where smiles were not observed, mood was negatively correlated with voltage (p=0.0591 for right brain and p=0.0086 for left). Smile and laughter-inducing sites were located relatively medial, posterior, and deep in the ALIC-NA. The presence of stimulation induced laughter predicted improvement in OCD symptoms at 2 years. The higher the percentage of laugh conditions experienced in an individual patient, the greater the reduction in YBOCS (24 months, p=0.034). Other correlations between clinical outcomes and percent of smile/laugh conditions were not significant. These stimulation-induced behaviors were less frequently observed with 1 and 2-month postoperative test stimulation and were not observed at subsequent test stimulation sessions. Intraoperative stimulation-induced laughter may predict long-term OCD response to DBS. Identifying other potential response predictors for OCD will become increasingly important as more patients are implanted with DBS devices. A larger study is needed to better delineate the relationship between induced intraoperative and postoperative emotional behavior and clinical outcome in patients treated with DBS therapy.

A study of laughter and dissociation: distinct correlates of laughter and smiling during bereavement.

PubMed

Keltner, D; Bonanno, G A

1997-10-01

Laughter facilitates the adaptive response to stress by increasing the psychological distance from distress and by enhancing social relations. To test these hypotheses, the authors related measures of bereaved adults' laughter and smiling 6 months postloss to measures of their (a) subjective emotion and dissociation from distress, (b) social relations, and (c) responses they evoked in others. Duchenne laughter, which involves orbicularis oculi muscle action, related to self-reports of reduced anger and increased enjoyment, the dissociation of distress, better social relations, and positive responses from strangers, whereas non-Duchenne laughter did not. Lending credence to speculations in the ethological literature, Duchenne laughter correlated with different intrapersonal and interpersonal responses than Duchenne smiles. Discussion focuses on the relevance of these findings to theories of positive emotion.

The effects of laughter on post-prandial glucose levels and gene expression in type 2 diabetic patients.

This report mainly summarizes the results of our study in which the physiological effects of laughter--as a positive emotional expression--were analyzed with respect to gene expression changes to demonstrate the hypothesis that the mind and genes mutually influence each other. We observed that laughter suppressed 2-h postprandial blood glucose level increase in patients with type 2 diabetes and analyzed gene expression changes. Some genes showed specific changes in their expression. In addition, we revealed that laughter decreased the levels of prorenin in blood; prorenin is involved in the onset of diabetic complications. Further, laughter normalized the expression of the prorenin receptor gene on peripheral blood leukocytes, which had been reduced in diabetic patients; this demonstrated that the inhibitory effects of laughter on the onset/deterioration of diabetic complications at the gene-expression level. In a subsequent study, we demonstrated the effects of laughter by discriminating 14 genes, related to natural killer (NK) cell activity, to exhibit continuous increases in expression as a result of laughter. Our results supported NK cell-mediated improvement in glucose tolerance at the gene-expression level. In this report, we also review other previous studies on laughter.

The Informational Patterns of Laughter

Laughter is one of the most characteristic -and enigmatic- communicational traits of human individuals. Its analysis has to take into account a variety of emotional, social, cognitive, and communicational factors densely interconnected. In this article we study laughter just as an auditive signal (as a 'neutral' information carrier), and we compare its structure with the regular traits of linguistic signals. In the experimental records of human laughter that we have performed, the most noticeable trait is the disorder content of frequencies. In comparison with the sonograms of vowels, the information content of which appears as a characteristic, regular function of the first vibration modes of the dynamic system formed, for each vowel, by the vocal cords and the accompanying resonance of the vocalization apparatus, the sonograms of laughter are highly irregular. In the episodes of laughter, a highly random content in frequencies appears, reason why it cannot be considered as a genuine codification of patterned information like in linguistic signals. In order to numerically gauge the disorder content of laughter frequencies, we have performed several "entropy" measures of the spectra -trying to unambiguously identify spontaneous laughter from "faked", articulated laughter. Interestingly, Shannon's entropy (the most natural candidate) performs rather poorly.

In the medical field, laughter has been studied for its beneficial effects on health and as a therapeutic method to prevent and treat major medical diseases. However, very few works, if any, have explored the predictive potential of laughter and its potential use as a diagnostic tool. We registered laughs of depressed patients (n=30) and healthy controls (n=20), in total 934 laughs (517 from patients and 417 from controls). All patients were tested by the Hamilton Depression Rating Scale (HDRS). The processing was made in Matlab, with calculation of 8 variables per laugh plosive. General and discriminant analysis distinguished patients, controls, gender, and the association between laughter and HDRS test. Depressed patients and healthy controls differed significantly on the type of laughter, with 88% efficacy. According to the Hamilton scale, 85.47% of the samples were correctly classified in males, and 66.17% in women, suggesting a tight relationship between laughter and the depressed condition. (i) The compilation of humorous videos created to evoke laughter implied quite variable chances of laughter production. (ii) Some laughing subjects might not feel comfortable when recording. (iii) Evaluation of laughter episodes depended on personal inspection of the records. (iv) Sample size was relatively small and may not be representative of the general population afflicted by depression. Laughter may be applied as a diagnostic tool in the onset and evolution of depression and, potentially, of neuropsychiatric pathologies. The sound structures of laughter reveal the underlying emotional and mood states in interpersonal relationships. Copyright © 2014 Elsevier B.V. All rights reserved.

Insular cortex activity and the evocation of laughter.

PubMed

2016-06-01

The insular cortex is fundamentally involved in the processing of interoceptive information. It has been postulated that the integrative monitoring of the bodily responses to environmental stimuli is crucial for the recognition and experience of emotions. Because emotional arousal is known to be closely coupled to functions of the anterior insula, we suspected laughter to be associated primarily with neuronal activity in this region. An anatomically constrained re-analysis of our imaging data pertaining to ticklish laughter, to inhibited ticklish laughter, and to voluntary laughter revealed regional differences in the levels of neuronal activity in the posterior and mid-/anterior portions of the insula. Ticklish laughter was associated specifically with right ventral anterior insular activity, which was not detected under the other two conditions. Hence, apparently, only laughter that is evoked as an emotional response bears the signature of autonomic arousal in the insular cortex. © 2015 Wiley Periodicals, Inc.

Humans express laughter differently depending on the context: polite titters of agreement are very different from explosions of mirth. Using functional MRI, we explored the neural responses during passive listening to authentic amusement laughter and controlled, voluntary laughter. We found greater activity in anterior medial prefrontal cortex (amPFC) to the deliberate, Emitted Laughs, suggesting an obligatory attempt to determine others' mental states when laughter is perceived as less genuine. In contrast, passive perception of authentic Evoked Laughs was associated with greater activity in bilateral superior temporal gyri. An individual differences analysis found that greater accuracy on a post hoc test of authenticity judgments of laughter predicted the magnitude of passive listening responses to laughter in amPFC, as well as several regions in sensorimotor cortex (in line with simulation accounts of emotion perception). These medial prefrontal and sensorimotor sites showed enhanced positive connectivity with cortical and subcortical regions during listening to involuntary laughter, indicating a complex set of interacting systems supporting the automatic emotional evaluation of heard vocalizations.

Laughter Among Deaf Signers

Provine, Robert R.; Emmorey, Karen

2008-01-01

The placement of laughter in the speech of hearing individuals is not random but “punctuates” speech, occurring during pauses and at phrase boundaries where punctuation would be placed in a transcript of a conversation. For speakers, language is dominant in the competition for the vocal tract since laughter seldom interrupts spoken phrases. For users of American Sign Language, however, laughter and language do not compete in the same way for a single output channel. This study investigated whether laughter occurs simultaneously with signing, or punctuates signing, as it does speech, in 11 signed conversations (with two to five participants) that had at least one instance of audible, vocal laughter. Laughter occurred 2.7 times more often during pauses and at phrase boundaries than simultaneously with a signed utterance. Thus, the production of laughter involves higher order cognitive or linguistic processes rather than the low-level regulation of motor processes competing for a single vocal channel. In an examination of other variables, the social dynamics of deaf and hearing people were similar, with “speakers” (those signing) laughing more than their audiences and females laughing more than males.

Telling Friend from Foe: Listeners Are Unable to Identify In-Group and Out-Group Members from Heard Laughter.

Group membership is important for how we perceive others, but although perceivers can accurately infer group membership from facial expressions and spoken language, it is not clear whether listeners can identify in- and out-group members from non-verbal vocalizations. In the current study, we examined perceivers' ability to identify group membership from non-verbal vocalizations of laughter, testing the following predictions: (1) listeners can distinguish between laughter from different nationalities and (2) between laughter from their in-group, a close out-group, and a distant out-group, and (3) greater exposure to laughter from members of other cultural groups is associated with better performance. Listeners ( n = 814) took part in an online forced-choice classification task in which they were asked to judge the origin of 24 laughter segments. The responses were analyzed using frequentist and Bayesian statistical analyses. Both kinds of analyses showed that listeners were unable to accurately identify group identity from laughter. Furthermore, exposure did not affect performance. These results provide a strong and clear demonstration that group identity cannot be inferred from laughter.

Exploration of the neural correlates of ticklish laughter by functional magnetic resonance imaging.

The burst of laughter that is evoked by tickling is a primitive form of vocalization. It evolves during an early phase of postnatal life and appears to be independent of higher cortical circuits. Clinicopathological observations have led to suspicions that the hypothalamus is directly involved in the production of laughter. In this functional magnetic resonance imaging investigation, healthy participants were 1) tickled on the sole of the right foot with permission to laugh, 2) tickled but asked to stifle laughter, and 3) requested to laugh voluntarily. Tickling that was accompanied by involuntary laughter activated regions in the lateral hypothalamus, parietal operculum, amygdala, and right cerebellum to a consistently greater degree than did the 2 other conditions. Activation of the periaqueductal gray matter was observed during voluntary and involuntary laughter but not when laughter was inhibited. The present findings indicate that hypothalamic activity plays a crucial role in evoking ticklish laughter in healthy individuals. The hypothalamus promotes innate behavioral reactions to stimuli and sends projections to the periaqueductal gray matter, which is itself an important integrative center for the control of vocalization. A comparison of our findings with published data relating to humorous laughter revealed the involvement of a common set of subcortical centers.

[Laughter and depression: hypothesis of pathogenic and therapeutic correlation].

2010-01-01

Laughter is a very common behaviour in everyday life, nevertheless scientific literature is lacking in studies which examine closely its nature. The study aims are: to summarise the present knowledge about laughter and its relation with depression and to make hypotheses on its possible therapeutic function. In the first part of the review the main data existing about encephalic structures involved in laughter genesis, which show participation of cortical and subcortical regions, are reported and the effects of laughter on the organism physiologic equilibrium, particularly on the neuroendocrine and immune systems, are described. In the second part, scientific evidence about the influence of depression on the ability to laugh are referred, which suggests that reduction of laughter frequency is a symptom of the disease and that its increase may be used as a marker of clinical improvement. Finally, the main assumptions supporting the hypothesis of the therapeutic action of laughter on depression are examined: first of all, it has been demonstrated that laughter is able to improve mood directly and to moderate negative consequences of stressful events on psychological well-being; in addition, it is possible that the stimulation of particular cerebral regions, involved in depression pathogenesis, and the normalisation of the hypothalamic pituitary adrenocortical system dysfunctions, both mediated by laughter, can counteract efficiently depressive symptoms; finally, the favourable effects of laughter on social relationships and physical health may have a role in influencing the ability of depressed patients to face the disease.

Objective To measure energy expenditure (EE) and heart rate (HR) during genuine laughter. Design Experimental trial of viewing film clips in four cycles either intended to evoke laughter (humorous −10 min) or unlikely to elicit laughter (not humorous −5 min) under strictly controlled conditions of a whole-room indirect calorimeter equipped with audio recording system. Participants Forty five adult friend dyads in either same-sex male (n=7), same-sex female (n=21) and mix-sex male-female (n=17); age 18–34 years; body mass index 24.7±4.9 (range 17.9–41.1). Measurements Energy expenditure in a whole-room indirect calorimeter, HR using Polar HR monitor. Laugh rate, duration and type from digitized audio data using a computerized system and synchronized with HR and EE results. Results Laughter EE was 0.79±1.30 kJ/min (0.19±0.31 kcal/min) higher than resting EE (P<0.001, 95% confidence interval=0.75–0.88 kJ/min), ranging from −2.52 to 9.67 kJ/min (−0.60–2.31 kcal/min). Heart rate during laughter segments increased above resting by 2.1±3.8 beats/min, ranging from −7.6 to 26.8 beats/min. Laughter EE was correlated with HR (rs=0.250, P<0.01). Both laughter EE and HR were positively correlated with laughter duration (rs=0.282 and 0.337, both P<0.001) and rate (rs=0.256 and 0.298, both P<0.001). Conclusion Genuine voiced laughter causes a 10–20% increase in EE and HR above resting values, which means that 10–15 min of laughter per day could increase total EE by 40–170 kJ (10–40 kcal).

Putting Laughter in Context: Shared Laughter as Behavioral Indicator of Relationship Well-Being

Laughter is a pervasive human behavior that most frequently happens in a social context. However, data linking the behavior of laughter with psychological or social outcomes is exceptionally rare. Here, we draw attention to shared laughter as a useful objective marker of relationship well-being. Spontaneously-generated laughs of 71 heterosexual romantic couples were coded from a videorecorded conversation about how the couple first met. Multilevel models revealed that, while controlling for all other laughter present, the proportion of the conversation spent laughing simultaneously with the romantic partner was uniquely positively associated with global evaluations of relationship quality, closeness, and social support. Results are discussed with respect to methodological considerations and theoretical implications for relationships and behavioral research more broadly. PMID:26957946

Analysis and synthesis of laughter

There is much enthusiasm in the text-to-speech community for synthesis of emotional and natural speech. One idea being proposed is to include emotion dependent paralinguistic cues during synthesis to convey emotions effectively. This requires modeling and synthesis techniques of various cues for different emotions. Motivated by this, a technique to synthesize human laughter is proposed. Laughter is a complex mechanism of expression and has high variability in terms of types and usage in human-human communication. People have their own characteristic way of laughing. Laughter can be seen as a controlled/uncontrolled physiological process of a person resulting from an initial excitation in context. A parametric model based on damped simple harmonic motion to effectively capture these diversities and also maintain the individuals characteristics is developed here. Limited laughter/speech data from actual humans and synthesis ease are the constraints imposed on the accuracy of the model. Analysis techniques are also developed to determine the parameters of the model for a given individual or laughter type. Finally, the effectiveness of the model to capture the individual characteristics and naturalness compared to real human laughter has been analyzed. Through this the factors involved in individual human laughter and their importance can be better understood.

Infant laughter is a rewarding experience. It activates neural reward circuits and promotes parental proximity and care, thus facilitating parent-infant attachment. The neuropeptide oxytocin might enhance the incentive salience of infant laughter by modulating neural circuits related to the perception of infant cues. In a randomized controlled trial with functional magnetic resonance imaging we investigated the influence of intranasally administered oxytocin on functional brain connectivity in response to infant laughter. Blood oxygenation level-dependent responses to infant laughter were measured in 22 nulliparous women who were administered oxytocin and 20 nulliparous women who were administered a placebo. Elevated oxytocin levels reduced activation in the amygdala during infant laughter and enhanced functional connectivity between the amygdala and the orbitofrontal cortex, the anterior cingulate, the hippocampus, the precuneus, the supramarginal gyri, and the middle temporal gyrus. Increased functional connectivity between the amygdala and regions involved in emotion regulation may reduce negative emotional arousal while enhancing the incentive salience of the infant laughter.

The common scenario described in a few reports involved episodes of fortuitous laughter, sometimes followed by a short prodrome of lightheadedness, facial flushing, and dizziness, followed by an episode of definite syncope. There were no seizure-like movements, automatisms, or bladder or bowel incontinence. After the syncopal episodes that were seconds in length, the patients regained consciousness, and at that point were fully oriented. These episodes could recur in a similar situation with such laughter. Many of these patients subsequently underwent full syncope workups, without elucidating a primary cardiac or neurologic cause. In this review of laughter-induced syncope, we describe a patient of ours who fit these descriptions. This phenomenon is likely a subtype of benign Valsalva-related syncope, with autonomic reflex arcs coming into play that ultimately result in global cerebral hypoperfusion. Besides the Valsalva produced by a great fit of laughter, laughter itself has its own neuroendocrine and vasculature effects that may play a role.

This cross-cultural study explored along with various personality factors the relationship between laughter and disease prevalence. Previous studies have only determined the effect of laughter on various health dimensions, whereas, this study quantified the level of laughter that was beneficial or detrimental to health. There were a total of 730 participants between the ages of eighteen and thirty-nine years. 366 participants were from Aurangabad, India (AUR), and 364 participants were from Mississauga, Canada (MISS). The participants were provided a survey assessing demographics, laughter, lifestyle, subjective well-being, life satisfaction, emotional well-being and health dimensions. In AUR, a beneficial effect of laughter was mediated through moderate levels (level two) of laughter, whereas both low (level one) and high (level three) levels had no effect. Similarly, in MISS, the beneficial effect was mediated through level two, but a negative effect was also seen at level three. This could be attributable to a higher prevalence of bronchial asthma in western countries. Laughter was associated with emotional well-being in MISS and life satisfaction in AUR, providing cross cultural models to describe the interactions between laughter and disease. This study validated the correlation between emotional well-being and life satisfaction, with a stronger correlation seen in MISS, suggesting that individualists rely more on their emotional well-being to judge their life satisfaction. In conclusion, there is a benefit to clinicians to incorporate laughter history into their general medical history taking. Future research should consider developing mechanisms to explain the effects of level two, determine specific systemic effects and obtain more samples to generalize the cross cultural differences.

To assess the potential of laughter and humour interventions to increase well-being in a general population of adults aged 60 plus; and to develop a classification to compare approaches and potential benefits of different intervention types. A systematic search of Web of Science, PubMed/MEDLINE, PsychInfo, AMED, and PsychArticles used inclusive terms relating to laughter and humour interventions. A realist synthesis approach enabled heterogeneous interventions to be compared pragmatically. Five laughter interventions, and one humour intervention, using one or more outcome related to well-being, were considered for inclusion after screening 178 primary research papers. The five laughter interventions, representing a sample of 369 participants, were retained. Well-being related outcome measures reported in each intervention informed efficacy; Joanna Briggs Institute tools appraised design; and a realist approach enabled heterogeneous interventions to be measured on their overall potential to provide an evidence base. Well-being related measures demonstrated at least one significant positive effect in all interventions. Confounding factors inherent in the intervention types were observed. Individual participant laughter was not reported. Laughter and humour interventions appear to enhance well-being. There is insufficient evidence for the potential of laughter itself to increase well-being as interventions contained a range of confounding factors and did not measure participant laughter. Interventions that isolate, track, and measure the parameters of individual laughter are recommended to build evidence for these potentially attractive and low-risk interventions. The classification proposed may guide the development of both evidence-oriented and population-appropriate intervention designs. Crown Copyright © 2018. Published by Elsevier Ltd.

Although laughter forms an important part of human non-verbal communication, it has received rather less attention than it deserves in both the experimental and the observational literatures. Relaxed social (Duchenne) laughter is associated with feelings of wellbeing and heightened affect, a proximate explanation for which might be the release of endorphins. We tested this hypothesis in a series of six experimental studies in both the laboratory (watching videos) and naturalistic contexts (watching stage performances), using change in pain threshold as an assay for endorphin release. The results show that pain thresholds are significantly higher after laughter than in the control condition. This pain-tolerance effect is due to laughter itself and not simply due to a change in positive affect. We suggest that laughter, through an endorphin-mediated opiate effect, may play a crucial role in social bonding. PMID:21920973

Laughter perception in social anxiety.

PubMed

Ritter, Jan; Brück, Carolin; Jacob, Heike; Wildgruber, Dirk; Kreifelts, Benjamin

2015-01-01

Laughter is a powerful signal of social acceptance or rejection while the fear of being embarrassed and humiliated is central in social anxiety (SA). This type of anxiety is associated with cognitive biases indicating increased sensitivity to social threat as well as with deficits in emotion regulation. Both are thought to be implicated in the maintenance of social anxiety. Using laughter as a novel stimulus, we investigated cognitive biases and their modulation through emotion regulation and cue ambiguity in individuals with varying degrees of SA (N = 60). A combination of a negative laughter interpretation bias and an attention bias away from joyful/social inclusive laughter in SA was observed. Both biases were not attributable to effects of general anxiety and were closely correlated with the concept of gelotophobia, the fear of being laughed at. Thus, our study demonstrates altered laughter perception in SA. Furthermore, it highlights the usefulness of laughter as a highly prevalent social signal for future research on the interrelations of interpretation and attention biases in SA and their modulation through emotion regulation.

Laughter's influence on the intimacy of self-disclosure.

Gray, Alan W; Parkinson, Brian; Dunbar, Robin I

2015-03-01

If laughter functions to build relationships between individuals, as current theory suggests, laughter should be linked to interpersonal behaviors that have been shown to be critical to relationship development. Given the importance of disclosing behaviors in facilitating the development of intense social bonds, it is possible that the act of laughing may temporarily influence the laugher's willingness to disclose personal information. We tested this hypothesis experimentally by comparing the characteristics of self-disclosing statements produced by those who had previously watched one of three video clips that differed in the extent to which they elicited laughter and positive affect. The results show that disclosure intimacy is significantly higher after laughter than in the control condition, suggesting that this effect may be due, at least in part, to laughter itself and not simply to a change in positive affect. However, the disclosure intimacy effect was only found for observers' ratings of participants' disclosures and was absent in the participants' own ratings. We suggest that laughter increases people's willingness to disclose, but that they may not necessarily be aware that it is doing so.

Anxious laughter: Mauron's Renversement and Gogol's Overcoat.

PubMed

Bown, Alfie

2017-06-01

Inside and outside of psychoanalysis, laughter has often been thought of as relating to anxiety, with the usual line being that laughter can be a response to anxiety or a way of dealing with it. This article argues that laughter cannot be said to eradicate or 'deal with' anxiety and that laughter is always unsettling precisely because it contains anxiety and indicates its continuing threat. The article discusses Freud and Lacan on anxiety, as well as Charles Mauron, an understudied writer whose Psychocritique du Genre Comique was the only sustained study of psychoanalysis and comedy until very recently. I argue here that Mauron's idea of renversement holds a key to understanding the relationship between laughter and anxiety. Rather than using a collection of isolated examples to illustrate individual points, in the second half of the article I provide a more sustained discussion of these ideas in relation to Nicolai Gogol's short story "The Overcoat."

Formant characteristics of human laughter.

Although laughter is an important aspect of nonverbal vocalization, its acoustic properties are still not fully understood. Extreme articulation during laughter production, such as wide jaw opening, suggests that laughter can have very high first formant (F(1)) frequencies. We measured fundamental frequency and formant frequencies of the vowels produced in the vocalic segments of laughter. Vocalic segments showed higher average F(1) frequencies than those previously reported and individual values could be as high as 1100 Hz for male speakers and 1500 Hz for female speakers. To our knowledge, these are the highest F(1) frequencies reported to date for human vocalizations, exceeding even the F(1) frequencies reported for trained soprano singers. These exceptionally high F(1) values are likely to be based on the extreme positions adopted by the vocal tract during laughter in combination with physiological constraints accompanying the production of a "pressed" voice.

Transient mutism and pathologic laughter in the course of cerebellitis.

Dimova, Petia S; Bojinova, Veneta S; Milanov, Ivan G

2009-07-01

The phenomenon of cerebellar mutism with subsequent dysarthria is most commonly described as a part of posterior fossa syndrome after surgery for neoplasms in childhood. Pathologic laughter, on the other hand, is observed primarily in various neurologic diseases in adults. In the present case, a child manifested transient mutism and pathologic laughter during a severe cerebellitis. Headache, vertigo, and impaired consciousness developed during an acute respiratory infection. Thereafter, severe ataxia, mutism, and involuntary laughter became the main clinical features, as well as pyramidal signs. Magnetic resonance imaging revealed cerebellar swelling and T(2) hyperintensity. During steroid treatment, a gradual vanishing of the pathologic laughter and improvement of the motor and speech functions occurred. Recovery was slow and incomplete, and follow-up magnetic resonance imaging showed cerebellar atrophy. This case confirms that mutism is a rare, but possible, manifestation in acute parainfectious cerebellitis and provides a novel example of pathologic laughter during this disease in childhood.

Laughter as a social rejection cue: gelotophobia and transient cardiac responses to other persons' laughter and insult.

Other persons' laughter, normally perceived as a signal that persons are friendly and inviting others to approach, can also be perceived as a cue of social rejection. In this study, prerecorded laughter was placed in a realistic and personally relevant context, and participants' responses were related to gelotophobia, a trait predisposing to perceiving laughter as a cue of social rejection. Individuals with gelotophobia showed marked heart rate deceleration in response to the laughter stimulus, possibly indicating a "freezing-like" response. Moreover, cardiac responses to anger provocation by overtly insulting statements indicated heightened aggressive anger in response to cumulated social threat. The study adds to recent research showing specific cardiac responses to social rejection and to the literature on social rejection sensitivity by demonstrating the value of using well interpretable physiological measures in this research context.

Laughter in popular games and in sport. The other health of human play.

PubMed

Eichberg, Henning

2013-01-01

Hurling in Cornwall, la soule in Britanny, Shrovetide football in England: Popular games have normally been treated as forerunners of modern sport, sport having regulated the space and the time of the game, the (non-) violence of behaviour, the control of results, the planning, strategy, tactics, techniques and evaluation of the competitive action. This is told as a story of social improvement and progress--and about turning unhealthy wildness into civilized 'healthy' sport activity. What sociological analysis of game-playing tended to ignore was the laughter of the participants. With the seriousness of modern sport, as it was established in the nineteenth century, a culture of laughter disappeared. This study tries to counter this mainstream by a phenomenology of laughter in popular games. A contrasting attention is turned towards the seriousness of sporting competition, the smile in modern sport and fitness, and the 'underground' dimension of laughter in modern sports. By comparative analysis, laughter reveals as a bodily discourse about the imperfect human being. It tells an oppositional story about the perfectionism in the order of Western thinking--in sports as well as in health. The bodily 'physiology' of laughter, the exploding psychical energy, and the inter-bodily social relations in laughter and play and game point towards the multi-dimensionality of health, as it was formulated by WHO: as "physical, mental, and social well-being".

The purpose of this study was to describe humor and laughter in persons with cognitive impairment (PWCI) and caregivers who were recalling a shared experience in a focus group. Twenty participants attended an Art Engagement Activity at the Andy Warhol Art Museum, which included a guided tour and an art project. All PWCI had medically diagnosed cognitive disorders and all caregiver participants did not. Four focus groups were conducted and transcripts of audio-recorded sessions were transferred to a qualitative software program. Words, phrases, and episodes of humor and laughter were used to construct codes, which were refined during group analysis using constant comparison. Humor and laughter were present in all four focus groups. Emerging themes of humor included silliness, sarcasm, and commenting about hardships of dementia. Laughter was identified in segments with and without humor. Some PWCI were unable to follow social cues. Humor and laughter played a role in creating a safe social environment. PWCI were able to engage in humor during social interactions, yet some had difficulty recognizing social cues. Further study may reveal roles of humor and laughter in adaptation to cognitive decline and holistic interventions for improved quality of life.

Laughter differs in children with autism: an acoustic analysis of laughs produced by children with and without the disorder.

Few studies have examined vocal expressions of emotion in children with autism. We tested the hypothesis that during social interactions, children diagnosed with autism would exhibit less extreme laugh acoustics than their nonautistic peers. Laughter was recorded during a series of playful interactions with an examiner. Results showed that children with autism exhibited only one type of laughter, whereas comparison participants exhibited two types. No group differences were found for laugh duration, mean fundamental frequency (F(0)) values, change in F(0), or number of laughs per bout. Findings are interpreted to suggest that children with autism express laughter primarily in response to positive internal states, rather than using laughter to negotiate social interactions.

Abstract The aim of this study was to evaluate the association of laughter with subjective health independent of socioeconomic status and social participation among older people in Japan. We used the data of 26,368 individuals (men, 12,174; women, 14,194) 65 years or older who participated in the Japan Gerontological Evaluation Study (JAGES) in 2013. Participants provided information on laughter and self-rated health, depression, socioeconomic, and psychosocial factors. We evaluated laughter from three perspectives: frequency, opportunities, and interpersonal interactions. Even after adjustment for depression, sociodemographic factors, and social participation, the prevalence ratio for poor subjective health among women who never or almost never laugh was 1.78 (95% confidence interval, 1.48–2.15) compared with those who reported laughing every day. Similar associations were observed among men. Laughter may be an important factor for the promotion of general and mental health of older adults. The mechanisms linking laughter and health warrant further study. PMID:26649930

Synthesis of laughter by modifying excitation characteristics.

Thati, Sathya Adithya; Kumar K, Sudheer; Yegnanarayana, B

2013-05-01

In this paper, a method to synthesize laughter by modifying the excitation source information is presented. The excitation source information is derived by extracting epoch locations and instantaneous fundamental frequency using zero frequency filtering approach. The zero frequency filtering approach is modified to capture the rapidly varying instantaneous fundamental frequency in natural laugh signals. The nature of variation of excitation features in natural laughter is examined to determine the features to be incorporated in the synthesis of a laugh signal. Features such as pitch period and strength of excitation are modified in the utterance of vowel /a/ or /i/ to generate the laughter signal. Frication is also incorporated wherever appropriate. Laugh signal is generated by varying parameters at both call level and bout level. Experiments are conducted to determine the significance of different features in the perception of laughter. Subjective evaluation is performed to determine the level of acceptance and quality of synthesis of the synthesized laughter signal for different choices of parameter values and for different input types.

Towards a social functional account of laughter: Acoustic features convey reward, affiliation, and dominance.

2017-01-01

Recent work has identified the physical features of smiles that accomplish three tasks fundamental to human social living: rewarding behavior, establishing and managing affiliative bonds, and negotiating social status. The current work extends the social functional account to laughter. Participants (N = 762) rated the degree to which reward, affiliation, or dominance (between-subjects) was conveyed by 400 laughter samples acquired from a commercial sound effects website. Inclusion of a fourth rating dimension, spontaneity, allowed us to situate the current approach in the context of existing laughter research, which emphasizes the distinction between spontaneous and volitional laughter. We used 11 acoustic properties extracted from the laugh samples to predict participants' ratings. Actor sex moderated, and sometimes even reversed, the relation between acoustics and participants' judgments. Spontaneous laughter appears to serve the reward function in the current framework, as similar acoustic properties guided perceiver judgments of spontaneity and reward: reduced voicing and increased pitch, increased duration for female actors, and increased pitch slope, center of gravity, first formant, and noisiness for male actors. Affiliation ratings diverged from reward in their sex-dependent relationship to intensity and, for females, reduced pitch range and raised second formant. Dominance displayed the most distinct pattern of acoustic predictors, including increased pitch range, reduced second formant in females, and decreased pitch variability in males. We relate the current findings to existing findings on laughter and human and non-human vocalizations, concluding laughter can signal much more that felt or faked amusement.

[Dialogy of Laughter: a new concept introducing joy for health promotion based on dialogue, laughter, joy and the art of the clown].

PubMed

Matraca, Marcus Vinicius Campos; Wimmer, Gert; Araújo-Jorge, Tania Cremonini de

2011-10-01

The Dialogy of Laughter - a concept based upon the praxis of general health education performed with joy - is presented and discussed. Health is seen as a resource for life rather than a goal in life and promotion of health is a positive reaction leading to a broader, integrated and complex perception linking the environment, education, people, quality and style of life. Laughter can then be incorporated as a tool in health promotion as defended here. Considerations on dialogue, laughter, joy and the clown giving rise to the Dialogy of Laughter concept are presented. Dialogue, namely an exchange between two or more persons for the comprehension and transfer of ideas, is a methodology for joint thinking to produce new ideas and to share meaning, which is the essence of communication. Laughter is a universal phenomenon linked to aspects of culture, philosophy, history and health. It is dialogic, since through humor the comedy and the wit contained in each laugh, which is a communication code inherent to human nature, are revealed. Joy as a strategy for health promotion is highlighted and the art of the clown, using this art as an educational tool that can be integrated as a social technology, are adopted.

Although mental health problems such as depression after disasters have been reported, positive psychological factors after disasters have not been examined. Recently, the importance of positive affect to our health has been recognised. We therefore investigated the frequency of laughter and its related factors among residents of evacuation zones after the Great East Japan Earthquake of 2011. In a cross-sectional study on 52,320 participants aged 20 years and older who were included in the Fukushima Health Management Survey in Japan's fiscal year 2012, associations of the frequency of laughter with changes in lifestyle after the disaster, such as a changed work situation, the number of family members, and the number of address changes, and other sociodemographic, psychological, and lifestyle factors were examined using logistic regression analysis. The frequency of laughter was assessed using a single-item question: "How often do you laugh out loud?" The proportion of those who laugh almost every day was 27.1%. Multivariable models adjusted for sociodemographic, psychological, and lifestyle factors demonstrated that an increase in the number of family members and fewer changes of address were significantly associated with a high frequency of laughter. Mental health, regular exercise, and participation in recreational activities were also associated with a high frequency of laughter. Changes in lifestyle factors after the disaster were associated with the frequency of laughter in the evacuation zone. Future longitudinal studies are needed to examine what factors can increase the frequency of laughter.

The acoustic features of human laughter

2002-05-01

Remarkably little is known about the acoustic features of laughter, despite laughter's ubiquitous role in human vocal communication. Outcomes are described for 1024 naturally produced laugh bouts recorded from 97 young adults. Acoustic analysis focused on temporal characteristics, production modes, source- and filter-related effects, and indexical cues to laugher sex and individual identity. The results indicate that laughter is a remarkably complex vocal signal, with evident diversity in both production modes and fundamental frequency characteristics. Also of interest was finding a consistent lack of articulation effects in supralaryngeal filtering. Outcomes are compared to previously advanced hypotheses and conjectures about this species-typical vocal signal.

This study investigated which features of AVATAR laughter are perceived threatening for individuals with a fear of being laughed at (gelotophobia), and individuals with no gelotophobia. Laughter samples were systematically varied (e.g., intensity, laughter pitch, and energy for the voice, intensity of facial actions of the face) in three modalities: animated facial expressions, synthesized auditory laughter vocalizations, and motion capture generated puppets displaying laughter body movements. In the online study 123 adults completed, the GELOPH <15 > (Ruch and Proyer, 2008a,b) and rated randomly presented videos of the three modalities for how malicious, how friendly, how real the laughter was (0 not at all to 8 extremely). Additionally, an open question asked which markers led to the perception of friendliness/maliciousness. The current study identified features in all modalities of laughter stimuli that were perceived as malicious in general, and some that were gelotophobia specific. For facial expressions of AVATARS, medium intensity laughs triggered highest maliciousness in the gelotophobes. In the auditory stimuli, the fundamental frequency modulations and the variation in intensity were indicative of maliciousness. In the body, backwards and forward movements and rocking vs. jerking movements distinguished the most malicious from the least malicious laugh. From the open answers, the shape and appearance of the lips curling induced feelings that the expression was malicious for non-gelotophobes and that the movement round the eyes, elicited the face to appear as friendly. This was opposite for gelotophobes. Gelotophobia savvy AVATARS should be of high intensity, containing lip and eye movements and be fast, non-repetitive voiced vocalization, variable and of short duration. It should not contain any features that indicate a down-regulation in the voice or body, or indicate voluntary/cognitive modulation. PMID:25477803

Melatonin is involved in sleep, and the levels of blood melatonin in patients with AE are decreased in comparison to healthy subjects. However, the levels of breast-milk melatonin had only been reported in healthy subjects. Laughter increased natural killer cell activity in blood and free radical-scavenging capacity in saliva in healthy subjects. Thus, the effect of laughter on the levels of breast-milk melatonin was studied in mothers with AE. Moreover, the effect of feeding with breast milk after laughter on allergic responses in infants was studied. Forty-eight infants aged 5-6 months were enrolled. All of the infants had AE and were allergic to latex and house dust mite (HDM). Half (n=24) of the mothers of these infants were patients with AE, while another 24 mothers were healthy subjects. The mothers viewed either an 87-min humorous DVD (Modern Times, featuring Charlie Chaplin) or an 87-min nonhumorous weather information DVD at 2000 h. After viewing, breast milk was collected sequentially from 2200, 2400, 0200, 0400 to 0600 h. The levels of breast-milk melatonin were measured. In addition, skin wheal responses to HDM and histamine were studied in infants. Laughter caused by viewing a humorous DVD increased the levels of breast-milk melatonin in both mothers with AE and healthy mothers. In addition, allergic responses to latex and HDM of infants were reduced by feeding with breast milk after laughter of mothers with AE or of healthy mothers. Laughter increased the levels of breast-milk melatonin in both mothers with AE and healthy mothers, and feeding infants with increased levels of melatonin-containing milk reduced allergic responses in infants. Thus, laughter of mothers may be helpful in the treatment of infants with AE.

Increased discriminability of authenticity from multimodal laughter is driven by auditory information.

Lavan, Nadine; McGettigan, Carolyn

We present an investigation of the perception of authenticity in audiovisual laughter, in which we contrast spontaneous and volitional samples and examine the contributions of unimodal affective information to multimodal percepts. In a pilot study, we demonstrate that listeners perceive spontaneous laughs as more authentic than volitional ones, both in unimodal (audio-only, visual-only) and multimodal contexts (audiovisual). In the main experiment, we show that the discriminability of volitional and spontaneous laughter is enhanced for multimodal laughter. Analyses of relationships between affective ratings and the perception of authenticity show that, while both unimodal percepts significantly predict evaluations of audiovisual laughter, it is auditory affective cues that have the greater influence on multimodal percepts. We discuss differences and potential mismatches in emotion signalling through voices and faces, in the context of spontaneous and volitional behaviour, and highlight issues that should be addressed in future studies of dynamic multimodal emotion processing.

We present the case of a patient with ischemic heart disease and intermittent left bundle branch block, reproducibly induced by laughter. Following treatment of ischemia with successful deployment of a drug-eluting stent, no further episodes of inducible LBBB were seen. Transient ischemia, exacerbated by elevated intrathoracic pressure during laughter, may have contributed to onset of this phenomenon. © 2012 Wiley Periodicals, Inc.

Laughter, Humor, and Cancer: Delicate Moments and Poignant Interactional Circumstances.

PubMed

Beach, Wayne A; Prickett, Erin

2017-07-01

Conversation analysis is employed to examine transcribed excerpts drawn from a subsample of 75 naturally occurring and video recorded interviews between cancer patients and 30 doctors. Close examination is provided of how cancer patients initiate, and doctors respond, to laughter and humor during oncology interviews. Interactions demonstrate that communication about the disease "cancer" shares qualities similar to other medical areas (e.g., primary care): the tendency for patients to initiate laughter or humor to address troubling and challenging circumstances; and that during moments when patients address personal matters, doctors are not invited and do not reciprocate with shared laughter and humor. Prominent in talk about cancer are various precarious circumstances, awkward and delicate moments mirroring the lived experiences of cancer patients (e.g., when patients attempt to minimize fears, justify that they are well when threatened with sickness, claim normality in the midst of chronic conditions, and take stances that weight loss and gain are not problematic). These examples provide a compelling case that routine cancer care involves many poignant situations managed through laughter and humor. Implications are raised for how quality care might be improved through grounded understandings of laughter, humor, and cancer.

An acoustic analysis of laughter produced by congenitally deaf and normally hearing college students.

Makagon, Maja M; Funayama, E Sumie; Owren, Michael J

2008-07-01

Relatively few empirical data are available concerning the role of auditory experience in nonverbal human vocal behavior, such as laughter production. This study compared the acoustic properties of laughter in 19 congenitally, bilaterally, and profoundly deaf college students and in 23 normally hearing control participants. Analyses focused on degree of voicing, mouth position, air-flow direction, temporal features, relative amplitude, fundamental frequency, and formant frequencies. Results showed that laughter produced by the deaf participants was fundamentally similar to that produced by the normally hearing individuals, which in turn was consistent with previously reported findings. Finding comparable acoustic properties in the sounds produced by deaf and hearing vocalizers confirms the presumption that laughter is importantly grounded in human biology, and that auditory experience with this vocalization is not necessary for it to emerge in species-typical form. Some differences were found between the laughter of deaf and hearing groups; the most important being that the deaf participants produced lower-amplitude and longer-duration laughs. These discrepancies are likely due to a combination of the physiological and social factors that routinely affect profoundly deaf individuals, including low overall rates of vocal fold use and pressure from the hearing world to suppress spontaneous vocalizations.

Laughter education and the psycho-physical effects: introduction of smile-sun method.

PubMed

Takayanagi, Kazue

2007-12-01

With the aim of reducing cases of bully and suicide, 34 core laughter producers and 179 laughter producers were educated using Smile-Sun Messages in Aomori Prefecture. The purpose of this paper is to explore the key to spontaneous laughter for further application to healthcare settings. Andragogy is the backbone idea. The author modified as seven tools such as sharing the objective, learning by heart, concentration, focusing on points, repetition, humor and evaluation. The contents of Smile-Sun Messages are as follows: 1. I love myself, 2. I love to make you happy, 3. I sympathize, 4. "Let's think of it this way", 5. Talk in P-N-P, 6. "I" message with eye-contact and love and 7. Thanks for all. There is no curriculum on how to laugh. Participants gained self confidence by having their good points praised by others. Their depression decreased. Spontaneous laughter arose from participants. They all improved physically in terms of appearance, posture and attitude. There are some reports of better fingering in piano playing in 2 ladies, pain relief in a patient with cancer and improved walking without using a stick for 2 ladies with rheumatoid arthritis and a limp due to an unknown cause. Spontaneous laughter can be drawn when self-confidence is recognized. With Smile-Sun Messages in hospitals and healing environments, spontaneous laughter can be drawn from patients which will decrease their depression and help them recover rapidly from their illness.

Presidential laugh lines. Candidate display behavior and audience laughter in the 2008 primary debates.

PubMed

Stewart, Patrick A

2010-09-01

Political humor has long been used by candidates to mobilize supporters by enhancing status or denigrating the opposition. Research concerning laughter provides insight into the building of social bonds; however, little research has focused on the nonverbal cues displayed by the individual making humorous comments. This study first investigates whether there is a relationship between facial display behavior and the presence and strength of laughter. Next, the analysis explores whether specific candidate displays during a humorous comment depend on the target of the comment. This paper analyzes the use of humor by Republican and Democratic candidates during ten 2008 presidential primary debates. Data analyzed here employs laughter as an indicator of a successful humorous comment and documents candidate display behavior in the seconds immediately preceding and during each laughter event. Findings suggest specific facial displays play an important communication role. Different types of smiles, whether felt, false, or fear-based, are related to who laughs as well as how intensely the audience is judged to laugh.

Laughter Yoga, Adults Living With Parkinson׳s Disease, and Caregivers: A Pilot Study.

PubMed

DeCaro, Debra Swedberg; Constantine Brown, Jodi L

2016-01-01

This study explored outcomes of Laughter Yoga in adults with Parkinson׳s disease (PD) and their caregivers. Laughter has been shown to generally improve mood in physically healthy adults, and specifically in adults with heart disease or cancer, but little research exists regarding the impact of laughter in adults with Parkinson׳s disease. Low mood is frequently a co-morbid condition for adults with Parkinson׳s disease, and can negatively affect their caregivers. Pre-experimental (O1 × O2) pretest-posttest design. Data collection occurred at six unique PD support groups in Southern California. Participants (N = 85) comprised a convenience sample of adults diagnosed with Parkinson׳s disease (n = 47) and accompanying caregivers (n = 38). Subjects participated in a 45-min Laughter Yoga (LY) session conducted by a Certified Laughter Yoga Teacher. This study utilized the Laughter Yoga "How Do You Feel?" (HDYF) form. The form consists of a series of 10 scales labeled "well-being" measures including enthusiasm, energy level, mood, optimism, stress level, level of friendship with group members, level of awareness about breathing, level of muscle relaxation, level of mental relaxation, and ability to laugh without a reason. Paired sample t-tests reveal statistically significant improvements in well-being for adults with PD and their caregivers after attending an LY session. Therapists and other clinicians should consider utilizing this unique technique with adults with PD to address co-morbid low-mood conditions and include caregivers in the LY sessions for support and their own benefit.

Research shows that laughter has myriad health benefits, yet the medical community has not implemented it formally as a treatment. Patients awaiting organ transplantation have significant physical disabilities and are at risk for psychological distress. Attenuated heart rate variability (HRV) is a risk factor for a negative long-term outcome in some patients. The study intended to evaluate the clinical utility of laughter yoga in improving psychological and physiological measures in outpatients awaiting organ transplantation. Positive results would indicate promising areas to pursue in a follow-up study. Six participants met for 10 sessions over 4 weeks. The research team measured each participant's heart rate, HRV, blood pressure (BP), and immediate mood before and after the laughter and control interventions. The team assessed participants' longer-term mood (anxiety and depression) at the study's initiation, after a no-treatment control week, and at the end of the study. The study occurred at the Department of Surgery and Medicine at the University of Arizona Health Sciences Center, Tucson. Participants were patients awaiting transplants (three heart and three lung), two women and four men (ages 51-69 y). Participants had received no major surgery in the 3 months prior to the intervention, did not have a hernia or uncontrolled hypertension, and did not fall into the New York Heart Association function class 4. The 20-minute laughter intervention involved breathing and stretching exercises, simulated laughter (ie, unconditional laughter that is not contingent on the environment), chanting, clapping, and a meditation. The 20-minute control intervention involved the study's personnel discussing health and study-related topics with the participants. The research team measured BP, heart rate, and HRV and administered the Profile of Mood States, Beck Anxiety Inventory, and Beck Depression Inventory-II to evaluate immediate and longer-term mood. The team had planned quantitative statistical analysis of the data at the study's initiation but did not complete it because the number of enrolled participants was too low for the analysis to be meaningful. The team visually examined the data, however, for trends that would indicate areas to examine further in a follow-up study. Participants showed improved immediate mood (vigor-activity and friendliness) and increased HRV after the laughter intervention. Both the laughter and control interventions appeared to improve longer-term anxiety. Two participants awaiting a lung transplant dropped out of the study, and no adverse events occurred. This pilot study suggests that laughter yoga may improve HRV and some aspects of mood, and this topic warrants further research.

Pseudobulbar affect is a common symptom in neurodegenerative diseases and can also result from lesions in cortical, subcortical and brainstem regions. In Parkinson's disease (PD), pseudobulbar affect (PBA) can occur as a wearing off phenomenon, manifested usually as crying without emotionality. In addition, subthalamic (STN) deep brain stimulation (DBS) has been reported to induce PBA in PD patients with no prior history of such episodes. We present a case of inappropriate laughter lacking mirth as a levodopa OFF phenomenon in a patient with PD, whose laughter also worsened with STN-DBS in his non-medicated state. Levodopa ameliorated his PBA both with and without stimulation. The case demonstrates pseudobulbar laughter as a levodopa OFF phenomenon that is also exacerbated by STN-DBS.

Background: Promotion and provision of individuals’ health is one of the bases for development in societies. Students’ mental health is very important in each society. Students of medical sciences universities, especially nursing students, are under various stresses in clinical environment, in addition to the stress they experience in theoretical education environment. With regard to the importance of nursing students’ general health and considering the various existing strategies to promote general health components, use of complementary treatments is more considered because of their better public acceptance, low costs, and fewer complications. One of the new strategies in this regard is laughter Yoga. The present study was conducted with an aim to define the effect of laughter Yoga on general health among nursing students. Materials and Methods: This is a quasi-experimental two-group three-step study conducted on 38 male nursing students in the nursing and midwifery school of Isfahan University of Medical Sciences in 2012. In the study group, eight 1 h sessions of laughter Yoga were held (two sessions a week), and in the control group, no intervention was conducted. The data of the present study were collected by Goldberg and Hiller's General Health Questionnaire and analyzed by SPSS version 12. Results: The findings showed a significant difference in the mean scores of general health before and after laughter Yoga intervention in the two groups of study and control. Conclusions: The findings showed that laughter Yoga had a positive effect on students’ general health and improved the signs of physical and sleep disorders, lowered anxiety and depression, and promoted their social function. Therefore, laughter Yoga can be used as one of the effective strategies on students’ general health. PMID:24554958

There are few reports of laughter and/or mirth evoked by electrical stimulation of the brain. In this study, we present a patient with intractable epilepsy in whom mirth and laughter was consistently produced during stimulation of the left inferior frontal gyrus (opercular part) using stereotactically placed depth electrodes. A review of the literature shows that cortical sites that produce mirth when stimulated are located in the dominant hemisphere close to language areas or cortical negative motor areas.

Quantitative Laughter Detection, Measurement, and Classification-A Critical Survey.

Cosentino, Sarah; Sessa, Salvatore; Takanishi, Atsuo

2016-01-01

The study of human nonverbal social behaviors has taken a more quantitative and computational approach in recent years due to the development of smart interfaces and virtual agents or robots able to interact socially. One of the most interesting nonverbal social behaviors, producing a characteristic vocal signal, is laughing. Laughter is produced in several different situations: in response to external physical, cognitive, or emotional stimuli; to negotiate social interactions; and also, pathologically, as a consequence of neural damage. For this reason, laughter has attracted researchers from many disciplines. A consequence of this multidisciplinarity is the absence of a holistic vision of this complex behavior: the methods of analysis and classification of laughter, as well as the terminology used, are heterogeneous; the findings sometimes contradictory and poorly documented. This survey aims at collecting and presenting objective measurement methods and results from a variety of different studies in different fields, to contribute to build a unified model and taxonomy of laughter. This could be successfully used for advances in several fields, from artificial intelligence and human-robot interaction to medicine and psychiatry.

To investigate the effect of laughter and mental stress on arterial stiffness and central hemodynamics. Arterial stiffness and wave reflections are independent predictors of cardiovascular risk. Chronic psychological stress is an independent risk factor for cardiovascular events, whereas acute stress deteriorates vascular function. Eighteen healthy individuals were studied on three occasions, according to a randomized, single-blind, crossover, sham procedure-controlled design. The effects of viewing a 30-minute segment of two films inducing laughter or stress were assessed. Carotid-femoral pulse wave velocity was used as an index of arterial stiffness; augmentation index was used as a measure of wave reflections. Laughter decreased pulse wave velocity (by 0.30 m/sec, p = .01), and augmentation index (by 2.72%, p = .05). Conversely, stress increased pulse wave velocity (by 0.29 m/sec, p = .05) and augmentation index (by 5.1%, p = .005). Laughter decreased cortisol levels by 1.67 microg/dl (p = .02), soluble P-selectin by 26 ng/ml (p = .02) and marginally von Willebrand factor (by 2.4%, p = .07) and increased total oxidative status (by 61 micromol/L, p < .001). Stress decreased interleukin-6 (by 0.11 pg/ml, p = .04) and increased total oxidative status (by 44 micromol/L, p = .007). Soluble CD40 ligand and fibrinogen remained unchanged. Positive (laughter) and negative (stress) behavioral interventions have divergent acute effects on arterial stiffness and wave reflections. These findings have important clinical implications extending the spectrum of lifestyle modifications that can ameliorate arterial function.

Abnormal laughter-like vocalisations replacing speech in primary progressive aphasia

2009-01-01

We describe ten patients with a clinical diagnosis of primary progressive aphasia (PPA) (pathologically confirmed in three cases) who developed abnormal laughter-like vocalisations in the context of progressive speech output impairment leading to mutism. Failure of speech output was accompanied by increasing frequency of the abnormal vocalisations until ultimately they constituted the patient's only extended utterance. The laughter-like vocalisations did not show contextual sensitivity but occurred as an automatic vocal output that replaced speech. Acoustic analysis of the vocalisations in two patients revealed abnormal motor features including variable note duration and inter-note interval, loss of temporal symmetry of laugh notes and loss of the normal decrescendo. Abnormal laughter-like vocalisations may be a hallmark of a subgroup in the PPA spectrum with impaired control and production of nonverbal vocal behaviour due to disruption of fronto-temporal networks mediating vocalisation.

Laughter as a social rejection cue: Influence of prior explicit experience of social rejection on cardiac signs of "freezing".

2018-06-01

The study aimed at investigating the immediate cardiac effect of the sudden perception of other people's laughter after experimentally manipulating healthy participants' proneness to experience laughter as a cue of social threat. We expected that participants would show cardiac signs of freezing (i.e., sustained heart rate deceleration immediately after perception of the laughter) after prior social rejection but not or less so after prior acceptance, due to an increased bias to perceive the ambiguous social signal as a cue of social threat and rejection after rejection had been primed. Contrary to expectations, the perception of other people's laughter elicited a decelerative (freezing) response regardless of whether it was preceded by the experience of social rejection or acceptance. The response was prolonged in participants who had been accepted beforehand compared to those who had been rejected. The findings indicate that, given a relevant social context, other people's laughter can be a powerful cue of social threat and rejection also in healthy individuals. Prolonged heart rate deceleration after an ambiguous social signal may facilitate the processing of significant social information in the socially threatening situation. The study adds to the literature rendering the course of the immediate transient heart rate response a useful tool in social rejection research. Additionally, the findings suggested that in some cases the further progress of transient heart rate changes in more extended time-windows (about 30 s) may provide additional relevant information about the processing of social cues.

Consequences of Laughter Upon Trunk Compression and Cortical Activation: Linear and Polynomial Relations

PubMed Central

Svebak, Sven

2016-01-01

Results from two studies of biological consequences of laughter are reported. A proposed inhibitory brain mechanism was tested in Study 1. It aims to protect against trunk compression that can cause health hazards during vigorous laughter. Compression may be maximal during moderate durations and, for protective reasons, moderate in enduring vigorous laughs. Twenty-five university students volunteered to see a candid camera film. Laughter responses (LR) and the superimposed ha-responses were operationally assessed by mercury-filled strain gauges strapped around the trunk. On average, the thorax compression amplitudes exceeded those of the abdomen, and greater amplitudes were seen in the males than in the females after correction for resting trunk circumference. Regression analyses supported polynomial relations because medium LR durations were associated with particularly high thorax amplitudes. In Study 2, power changes were computed in the beta and alpha EEG frequency bands of the parietal cortex from before to after exposure to the comedy “Dinner for one” in 56 university students. Highly significant linear relations were calculated between the number of laughs and post-exposure cortical activation (increase of beta, decrease of alpha) due to high activation after frequent laughter. The results from Study 1 supported the hypothesis of a protective brain mechanism that is activated during long LRs to reduce the risk of harm to vital organs in the trunk cavity. The results in Study 2 supported a linear cortical activation and, thus, provided evidence for a biological correlate to the subjective experience of mental refreshment after laughter. PMID:27547260

Humor, laughter, learning, and health! A brief review.

Savage, Brandon M; Lujan, Heidi L; Thipparthi, Raghavendar R; DiCarlo, Stephen E

2017-09-01

Human emotions, such as anxiety, depression, fear, joy, and laughter, profoundly affect psychological and physiological processes. These emotions form a set of basic, evolved functions that are shared by all humans. Laughter is part of a universal language of basic emotions that all humans recognize. Health care providers and educators may utilize the power of laughter to improve health and enhance teaching and learning. This is an important consideration because teaching is not just about content: it is also about forming relationships and strengthening human connections. In this context, when used effectively, humor is documented to build relationships and enhance performance. Specifically, humor improves student performance by attracting and sustaining attention, reducing anxiety, enhancing participation, and increasing motivation. Moreover, humor stimulates multiple physiological systems that decrease levels of stress hormones, such as cortisol and epinephrine, and increase the activation of the mesolimbic dopaminergic reward system. To achieve these benefits, it is important to use humor that is relevant to the course content and not disparaging toward others. Self-effacing humor illustrates to students that the teacher is comfortable making mistakes and sharing these experiences with the classroom. In this brief review, we discuss the history and relationship between humor, laughing, learning, and health with an emphasis on the powerful, universal language of laughter.

Pathological laughter as prodromal manifestation of transient ischemic attacks--case report and brief review.

PubMed

Dulamea, Adriana O; Matei, Costel; Mindruta, Ioana; Ionescu, Virgil

2015-10-12

Based on a case report, the authors reviewed the data about involuntary emotional expression disorder (IEED). IEED includes the syndromes of pathological laughing and crying (PLC) and emotional lability (EL). PLC is a rare disorder of emotional expression characterized by relatively uncontrollable episodes of laughter and crying or both that do not have an apparent motivating stimulus. Authors report the case of a 59-year-old man who presented with recurrent episodes of PLC of approximately 2 min duration, consisting of accelerated breathing, emission of guttural, snoring sounds, frowning of the eyebrows, followed by laughter accompanied by motor restlessness of all four limbs. PLC episodes preceded left carotid transient ischemic attacks (TIA's) manifested by reversible aphasia and right hemiparesis. Electroencephalography performed during PLC episodes revealed no spike-wave activity. Brain magnetic resonance imaging showed lacunar infarcts in the left lenticulo-capsulo-thalamic area and multiple round lesions in the cortical-subcortical and in the deep white matter of frontal-parietal-occipital lobes bilaterally, with T2 hyperintensity, T1 isointensity and no diffusion changes. The episodes were interpreted as transient ischemic attacks although gelastic seizures could not be excluded. The etiological investigations revealed unstable plaques on the left carotid artery bulb and the aortic arch and a degenerative mitral valve stenosis. The patient was treated first with antiplatelet therapy and antiepileptic drugs but PLC stopped only after anticoagulation was started. During follow-up the patient continued to have left carotid and vertebrobasilar TIA's being on oral anticoagulation. The patient became asymptomatic only after mitral valve replacement was performed. This case illustrates the difficulty distinguishing between gelastic epilepsy and TIA's in cases of PLC episodes and discuss the neuroanatomic bases and pathophysiology of this rare condition.

Apart from vasovagal attacks, other benign, neurally mediated syncopes include "situational" syncopes, which occur after urination, coughing, swallowing, or defecation. A healthy 42-year-old male patient presented to the neurology clinic with a long history of faints triggered by spontaneous laughter, especially after funny jokes. Physical and neurological examination, and electroencephalography and magnetic resonance imaging were unremarkable. There was no evidence to suggest cardiogenic causes, epilepsy, or cataplexy and a diagnosis of laughing syncope was made. Laughter-induced syncope is usually a single event in the majority of cases, but may present as recurrent attacks as in our case. Some cases occur in association with underlying neurological conditions. Prognosis is good in the case of neurally mediated attacks. Laughter may not be recognized by physicians as a cause of syncope, which may lead to unnecessary investigations or misdiagnosis, and affect patients' quality of life.

Humor theories and the physiological benefits of laughter.

PubMed

Wilkins, Julia; Eisenbraun, Amy Janel

2009-01-01

There are 3 main theories used to explain the functions of humor: (1) the relief theory, (2) the incongruity theory, and (3) the superiority theory. While these theories focus on the specific role that humor plays for people in situations such as dealing with misfortune, making sense of rule violations, and bonding with others, we propose that underlying each of these theories are the physiological benefits of laughter. We draw on findings from empirical studies on laughter to demonstrate that these physiological benefits occur regardless of the theory that is used to explain the humor function. Findings from these studies have important implications for nurse practitioners working in hospice settings, long-term care facilities, nursing homes, and hospitals.

The Use of Humor in Serious Mental Illness: A Review

PubMed Central

Gelkopf, Marc

2011-01-01

There is now a relatively good understanding of the broad range of direct and indirect effects of humor and laughter on perceptions, attitudes, judgments and emotions, which can potentially benefit the physical and psychological state. This article presents a review and discussion of the use of humor and laughter in treating people with serious mental illness, distinguishing between clinical papers on individual and group psychotherapy, and empirical research reports describing humor and laughter interventions. In spite of the exponential growth of the field over the last 30 years, I conclude that empirical studies are still lacking, the studies that do exist have major methodological shortcomings, and the field is in dire need of further investigation.

The evolution of laughter in great apes and humans

PubMed Central

Owren, Michael J; Zimmermann, Elke

2010-01-01

It has long been claimed that human emotional expressions, such as laughter, have evolved from nonhuman displays. The aim of the current study was to test this prediction by conducting acoustic and phylogenetic analyses based on the acoustics of tickle-induced vocalizations of orangutans, gorillas, chimpanzees, bonobos and humans. Results revealed both important similarities and differences among the various species’ vocalizations, with the phylogenetic tree reconstructed based on these acoustic data matching the well-established genetic relationships of great apes and humans. These outcomes provide evidence of a common phylogenetic origin of tickle-induced vocalizations in these taxa, which can therefore be termed “laughter” across all five species. Results are consistent with the claims of phylogenetic continuity of emotional expressions. Together with observations made on the use of laughter in great apes and humans, findings of this study further indicate that there were two main periods of selection-driven evolutionary change in laughter within the Hominidae, to a smaller degree, among the great apes and, most distinctively, after the separation of hominins from the last common ancestor with chimpanzees and bonobos.

We sought to evaluate the associations between frequency of daily laughter with heart disease and stroke among community-dwelling older Japanese women and men. We analyzed cross-sectional data in 20 934 individuals (10 206 men and 10 728 women) aged 65 years or older, who participated in the Japan Gerontological Evaluation Study in 2013. In the mail-in survey, participants provided information on daily frequency of laughter, as well as body mass index, demographic and lifestyle factors, and diagnoses of cardiovascular disease, hyperlipidemia, hypertension, and depression. Even after adjustment for hyperlipidemia, hypertension, depression, body mass index, and other risk factors, the prevalence of heart diseases among those who never or almost never laughed was 1.21 (95% CI, -1.03-1.41) times higher than those who reported laughing every day. The adjusted prevalence ratio for stroke was 1.60 (95% CI, 1.24-2.06). Daily frequency of laughter is associated with lower prevalence of cardiovascular diseases. The association could not be explained by confounding factors, such as depressive symptoms.

Laughter and the Management of Divergent Positions in Peer Review Interactions

PubMed Central

Raclaw, Joshua; Ford, Cecilia E.

2017-01-01

In this paper we focus on how participants in peer review interactions use laughter as a resource as they publicly report divergence of evaluative positions, divergence that is typical in the give and take of joint grant evaluation. Using the framework of conversation analysis, we examine the infusion of laughter and multimodal laugh-relevant practices into sequences of talk in meetings of grant reviewers deliberating on the evaluation and scoring of high-level scientific grant applications. We focus on a recurrent sequence in these meetings, what we call the score-reporting sequence, in which the assigned reviewers first announce the preliminary scores they have assigned to the grant. We demonstrate that such sequences are routine sites for the use of laugh practices to navigate the initial moments in which divergence of opinion is made explicit. In the context of meetings convened for the purposes of peer review, laughter thus serves as a valuable resource for managing the socially delicate but institutionally required reporting of divergence and disagreement that is endemic to meetings where these types of evaluative tasks are a focal activity.

To examine the effects of a once-weekly laughter and exercise program on physical and psychological health among elderly people living in the community. As a regular exercise program can be difficult to maintain, we provided a more enjoyable program to enhance adherence to exercise. A total of 27 individuals aged 60 years or older, without disabilities, were randomly assigned to either an immediate treatment group (n=14) or a delayed treatment group (n=13). The intervention was a 120-min session consisting of laughter and exercise, carried out once a week for 10 consecutive weeks. Measurements taken at baseline, 3 and 6 months included bodyweight, height, body fat, lean mass, bone mineral density, hemoglobin A1c (HbA(1c)), glucose, high-density lipoprotein and low-density lipoprotein cholesterol, and triglycerides, as well as self-rated health and psychological factors. All participants completed the 3-month program. Bone mineral density increased significantly in the immediate treatment group compared with the delayed treatment group during the first 3 months (P<0.001). In addition, HbA(1c) decreased significantly (P=0.001), and self-rated health increased significantly (P=0.012). The combination of a laughter and exercise program might have physiological and psychological health benefits for the elderly. Laughter might be an effective strategy to motivate the elderly to participate in physical activity. © 2012 Japan Geriatrics Society.

[Neurology of laughter and humour: pathological laughing and crying].

PubMed

Arias, Manuel

2011-10-01

Laughter, which is usually a healthy biological phenomenon, may be also a symptom of several severe brain pathologies. To review the neurobiological bases of laughter and humour, as well as those of pathological laughing and crying syndrome. At the mesencephalic-pontine junction there is a central coordinator of the nuclei that innervate the muscles involved in laughter (facial expression, respiratory and phonatory). This centre receives connections from three systems: inhibitory (pre-motor and motor cortex), excitatory (temporal cortex, amygdala, hypothalamus) and modulator (cerebellum). Humour is a complex phenomenon with a range of components: the perception of the unexpected incongruence (occipitotemporal area, prefrontal cortex), emotional (reward circuit) and volitional (temporal and frontal cortex). Functional magnetic resonance imaging studies do not reveal a markedly prominent role of the right frontal lobe in processing humour, as had been suggested in the classical studies. The causes of pathological laughing and crying syndrome can be classified in two groups: altered behaviour with unmotivated happiness (Angelman syndrome, schizophrenia, manias, dementia) and interference with the inhibitory/excitatory mechanisms (gelastic epilepsy, fou rire prodromique in strokes, multiple sclerosis, amyotrophic lateral sclerosis, Parkinson's disease and Parkinson-plus, traumatic injuries, tumours). Serotonin and noradrenalin reuptake inhibitors, levodopa, lamotrigine and the association of dextromethorphan/quinidine can be effective in certain cases of pathological laughing and crying. As human neurobiological phenomena, laughter and humour also belong to the field of clinical neurology; their processing is affected in a number of different diseases and, in certain cases, effective treatment can be established.

Three Decades Investigating Humor and Laughter: An Interview With Professor Rod Martin.

Martin, Rod; Kuiper, Nicholas A

2016-08-01

Since the start of the 21st century, the investigation of various psychological aspects of humor and laughter has become an increasingly prominent topic of research. This growth can be attributed, in no small part, to the pioneering and creative work on humor and laughter conducted by Professor Rod Martin. Dr. Martin's research interests in humor and laughter began in the early 1980s and continued throughout his 32 year long career as a professor of clinical psychology at the University of Western Ontario. During this time, Dr. Martin published numerous scholarly articles, chapters, and books on psychological aspects of humor and laughter. Professor Martin has just retired in July 2016, and in the present interview he recounts a number of research highlights of his illustrious career. Dr. Martin's earliest influential work, conducted while he was still in graduate school, stemmed from an individual difference perspective that focused on the beneficial effects of sense of humor on psychological well-being. This research focus remained evident in many of Professor Martin's subsequent investigations, but became increasingly refined as he developed several measures of different components of sense of humor, including both adaptive and maladaptive humor styles. In this interview, Dr. Martin describes the conceptualization, development and use of the Humor Styles Questionnaire, along with suggestions for future research and development. In doing so, he also discusses the three main components of humor (i.e., cognitive, emotional and interpersonal), as well as the distinctions and similarities between humor and laughter. Further highlights of this interview include Professor Martin's comments on such diverse issues as the genetic versus environmental loadings for sense of humor, the multifaceted nature of the construct of humor, and the possible limitations of teaching individuals to use humor in a beneficial manner to cope with stress and enhance their social and interpersonal relationships.

Laughter is a nonverbal vocal expression that often communicates positive affect and cooperative intent in humans. Temporally coincident laughter occurring within groups is a potentially rich cue of affiliation to overhearers. We examined listeners’ judgments of affiliation based on brief, decontextualized instances of colaughter between either established friends or recently acquainted strangers. In a sample of 966 participants from 24 societies, people reliably distinguished friends from strangers with an accuracy of 53–67%. Acoustic analyses of the individual laughter segments revealed that, across cultures, listeners’ judgments were consistently predicted by voicing dynamics, suggesting perceptual sensitivity to emotionally triggered spontaneous production. Colaughter affords rapid and accurate appraisals of affiliation that transcend cultural and linguistic boundaries, and may constitute a universal means of signaling cooperative relationships.

We investigated the effect of laughter on salivary endocrinological stress marker chromogranin A (CgA). In saliva samples collected from 11 healthy males before and after watching a comic film or a non-humorous control film, salivary CgA levels were determined by enzyme-linked immunosorbent assay (ELISA). Samples taken after watching the comic film showed increased levels of CgA. This tendency was more pronounced in individuals with lower initial levels of stress. The control samples showed no significant change in CgA levels. Stress score, subjectively evaluated using a visual analog scale, decreased significantly after watching the comic film. These findings suggest that, in addition to a stress relief effect, laughter can bring about feeling uplifted or fulfilled.

Smile and laughter elicited by electrical stimulation of the frontal operculum.

PubMed

Caruana, F; Gozzo, F; Pelliccia, V; Cossu, M; Avanzini, P

2016-08-01

Laughter and smile are typical expressions of mirth and fundamental means of social communication. Despite their general interest, the current knowledge about the brain regions involved in the production of these expressions is still very limited, and the principal insights come from electrical stimulation (ES) studies in patients, in which, nevertheless, laughter or smile have been elicited very rarely. Previous studies showed that laughter is evoked by the stimulation of nodes of an emotional network encompassing the anterior cingulate, the superior frontal and basal temporal cortex. A common feature of these stimulation studies is that the facial expression was always accompanied by motor awareness and often by mirth, in line with the affective functions attributed to these regions. Little is known, in contrast, on the neural basis of the voluntary motor control of this expression. The objective of this study was to investigate the effect of ES of the frontal operculum (FO), which is considered a crucial node for the linkage of the voluntary motor system for emotional expression and limbic emotional network. We report the case of ES applied to the frontal operculum (FO) in four patients with drug-resistant focal epilepsy undergoing stereo-electroencephalographic (SEEG) implantation of intracerebral electrodes. In all patients, ES applied to the FO produced laughter or smile. Interestingly, in one patient, the production of a smiling expression was also clearly accompanied by the lack of motor awareness. Since the lack of motor awareness has been previously observed only after the stimulation of the voluntary motor network, we speculate that FO is involved in the voluntary control of facial expressions, and is placed at the interface with the emotional network, gating limbic information to the motor system.

Neural correlates of the affective properties of spontaneous and volitional laughter types.

Lavan, Nadine; Rankin, Georgia; Lorking, Nicole; Scott, Sophie; McGettigan, Carolyn

2017-01-27

Previous investigations of vocal expressions of emotion have identified acoustic and perceptual distinctions between expressions of different emotion categories, and between spontaneous and volitional (or acted) variants of a given category. Recent work on laughter has identified relationships between acoustic properties of laughs and their perceived affective properties (arousal and valence) that are similar across spontaneous and volitional types (Bryant & Aktipis, 2014; Lavan et al., 2016). In the current study, we explored the neural correlates of such relationships by measuring modulations of the BOLD response in the presence of itemwise variability in the subjective affective properties of spontaneous and volitional laughter. Across all laughs, and within spontaneous and volitional sets, we consistently observed linear increases in the response of bilateral auditory cortices (including Heschl's gyrus and superior temporal gyrus [STG]) associated with higher ratings of perceived arousal, valence and authenticity. Areas in the anterior medial prefrontal cortex (amPFC) showed negative linear correlations with valence and authenticity ratings across the full set of spontaneous and volitional laughs; in line with previous research (McGettigan et al., 2015; Szameitat et al., 2010), we suggest that this reflects increased engagement of these regions in response to laughter of greater social ambiguity. Strikingly, an investigation of higher-order relationships between the entire laughter set and the neural response revealed a positive quadratic profile of the BOLD response in right-dominant STG (extending onto the dorsal bank of the STS), where this region responded most strongly to laughs rated at the extremes of the authenticity scale. While previous studies claimed a role for right STG in bipolar representation of emotional valence, we instead argue that this may in fact exhibit a relatively categorical response to emotional signals, whether positive or negative.

The positive psychology movement has created more interest in examining the potential value of experiencing positive emotions (e.g. humor, laughter and happiness) during the course of bereavement. This study of 292 recently widowed (5-24 weeks) men (39%) and women (61%) age 50 and over examined both the perceived importance of and actual experience of having positive emotions in their daily lives and how they might impact bereavement adjustments. We found that most of the bereaved spouses rated humor and happiness as being very important in their daily lives and that they were also experiencing these emotions at higher levels than expected. Experiencing humor, laughter and happiness was strongly associated with favorable bereavement adjustments (lower grief and depression) regardless of the extent to which the bereaved person valued having these positive emotions.

It entails severe personal and inter-personal problems including heightened aggression and possibly violence. Individuals with gelotophobia (n=30; 24 with social phobia or Cluster A diagnosis) and matched symptom-free controls (n=30) were drawn from a large screening sample (n=1440). EEG coherences were recorded during the confrontation with other people's affect expressions, to investigate the brain's modulatory control over the emotionally laden perceptual input. Gelotophobia was associated with more loose functional coupling of prefrontal and posterior cortex during the processing of expressions of anger and aggression, thus leaving the individual relatively unprotected from becoming affected by these social signals. The brain's response to social signals of anger/aggression and the accompanied heightened permeability for this kind of information explains the particular sensitivity to actual or supposed malicious aspects of laughter (and possibly of other ambiguous social signals) in individuals with gelotophobia, which represents the core feature of the condition. Heightened perception of stimuli that could be perceived as offensive, which is inherent in several psychiatric conditions, may be particularly evident in the fear of other persons' laughter.

The fear of embarrassment and humiliation is the central element of social anxiety. This frequent condition is associated with cognitive biases indicating increased sensitivity to signals of social threat, which are assumed to play a causal role in the maintenance of social anxiety. Here, we employed laughter, a potent medium for the expression of acceptance and rejection, as an experimental stimulus in participants selected for varying degrees of social anxiety to identify cerebral mediators of cognitive biases in social anxiety using functional magnetic resonance imaging in combination with mediation analysis. We directly demonstrated that cerebral activation patterns within the dorsal attention network including the left dorsolateral and dorsomedial prefrontal cortex mediate the influence of social anxiety on laughter perception. This mediation proved to be specific for social anxiety after correction for measures of general state and trait anxiety and occurred most prominently under bimodal audiovisual laughter presentation when compared with monomodal auditory or visual laughter cues. Considering the possibility to modulate cognitive biases and cerebral activity by neuropsychological trainings, non-invasive electrophysiological stimulation and psychotherapy, this study represents a starting point for a whole line of translational research projects and identifies promising targets for electrophysiological interventions aiming to alleviate cognitive biases and symptom severity in social anxiety.

Extent of cerebellar involvement in cognition and emotion is still a topic of ongoing research. In particular, the cerebellar role in humor processing and control of laughter is not well known. A hypermetric dysregulation of affective behavior has been assumed in cerebellar damage. Thus, we aimed at investigating humor comprehension and appreciation as well as the expression of laughter in 21 patients in the acute or subacute state after stroke restricted to the cerebellum, and in the same number of matched healthy control subjects. Patients with acute and subacute cerebellar damage showed preserved comprehension and appreciation of humor using a validated humor test evaluating comprehension, funniness and aversiveness of cartoons ("3WD Humor Test"). Additionally, there was no difference when compared to healthy controls in the number and intensity of facial reactions and laughter while observing jokes, humorous cartoons, or video sketches measured by the Facial Action Coding System. However, as depression scores were significantly increased in patients with cerebellar stroke, a concealing effect of accompanying depression cannot be excluded. Current findings add to descriptions in the literature that cognitive or affective disorders in patients with lesions restricted to the cerebellum, even in the acute state after damage, are frequently mild and might only be present in more sensitive or specific tests.

Review of pseudobulbar affect including a novel and potential therapy.

PubMed

Schiffer, Randolph; Pope, Laura E

2005-01-01

Pseudobulbar affect (PBA) is an affective disinhibition syndrome associated with various neuropathologies, which is characterized by involuntary and inappropriate outbursts of laughter and/or crying. The PBA syndrome can be socially and occupationally disabling, and it is largely unrecognized in clinical settings. Validated instruments to distinguish PBA from other disorders of affective regulation exist and could be used to improve recognition of the disorder. There is no pharmacological therapy with a Food and Drug Administration indication for PBA, although antidepressants and dopaminergic agents have been reported to show varying levels of treatment success. Recent evidence suggests that treatment with a fixed combination of dextromethorphan and the cytochrome P450 2D6 enzyme inhibitor, quinidine, can improve PBA. This review describes the clinical and neuropathological features of PBA, and presents an overview of current and future treatment approaches.

Benign violations: making immoral behavior funny.

PubMed

McGraw, A Peter; Warren, Caleb

2010-08-01

Humor is an important, ubiquitous phenomenon; however, seemingly disparate conditions seem to facilitate humor. We integrate these conditions by suggesting that laughter and amusement result from violations that are simultaneously seen as benign. We investigated three conditions that make a violation benign and thus humorous: (a) the presence of an alternative norm suggesting that the situation is acceptable, (b) weak commitment to the violated norm, and (c) psychological distance from the violation. We tested the benign-violation hypothesis in the domain of moral psychology, where there is a strong documented association between moral violations and negative emotions, particularly disgust. Five experimental studies show that benign moral violations tend to elicit laughter and amusement in addition to disgust. Furthermore, seeing a violation as both wrong and not wrong mediates behavioral displays of humor. Our account is consistent with evolutionary accounts of laughter, explains humor across many domains, and suggests that humor can accompany negative emotion.

Laughter consists of both motor and emotional aspects. The emotional component, known as mirth, is usually associated with the motor component, namely, bilateral facial movements. Previous electrical cortical stimulation (ES) studies revealed that mirth was associated with the basal temporal cortex, inferior frontal cortex, and medial frontal cortex. Functional neuroimaging implicated a role for the left inferior frontal and bilateral temporal cortices in humor processing. However, the neural origins and pathways linking mirth with facial movements are still unclear. We hereby report two cases with temporal lobe epilepsy undergoing subdural electrode implantation in whom ES of the left basal temporal cortex elicited both mirth and laughter-related facial muscle movements. In one case with normal hippocampus, high-frequency ES consistently caused contralateral facial movement, followed by bilateral facial movements with mirth. In contrast, in another case with hippocampal sclerosis (HS), ES elicited only mirth at low intensity and short duration, and eventually laughter at higher intensity and longer duration. In both cases, the basal temporal language area (BTLA) was located within or adjacent to the cortex where ES produced mirth. In conclusion, the present direct ES study demonstrated that 1) mirth had a close relationship with language function, 2) intact mesial temporal structures were actively engaged in the beginning of facial movements associated with mirth, and 3) these emotion-related facial movements had contralateral dominance.

Humor in psychiatric healing.

PubMed

Saper, B

1988-01-01

The oft-quoted aphorism that "laughter is the best medicine" is examined. Specifically, three big drops in the shower of claims regarding the benefits of humor in treating physical and mental disorders are evaluated. First, studies of the effects of mirth and laughter on the physiology of the body reveal both good and bad news. The meager evidence of the salutary effects of positive emotions on the cardiovascular, respiratory, immune and neuroendocrine systems, though apparently supportable on more or less scientific, rational and subjective grounds, needs much better verification from more extensive, replicable, and empirical research. Second, despite numerous claims, in the context of behavioral or psychosomatic medicine, that a joyful, optimistic, or humorous attitude can render a salubrious effect, almost to the extent of preventing illness and curing physical disease, the jury is still out and issuing dire warnings regarding too ready acceptance of this largely anecdotal evidence. Much careful "clinical trial" research needs to be mounted to determine the conditions under which humor works best, if at all. The type of patient, the kind of humor, the type and severity of illness, the psychosocial contexts-all of these factors should be considered. Third, the infusion of humor into psychotherapy is great news for some therapists and awful news for others. A number of more balanced approaches point up the probability that when mirth is incorporated into therapy judiciously, appropriately, and meaningfully it can be of value.

I thought that I heard you laughing: Contextual facial expressions modulate the perception of authentic laughter and crying.

It is well established that categorising the emotional content of facial expressions may differ depending on contextual information. Whether this malleability is observed in the auditory domain and in genuine emotion expressions is poorly explored. We examined the perception of authentic laughter and crying in the context of happy, neutral and sad facial expressions. Participants rated the vocalisations on separate unipolar scales of happiness and sadness and on arousal. Although they were instructed to focus exclusively on the vocalisations, consistent context effects were found: For both laughter and crying, emotion judgements were shifted towards the information expressed by the face. These modulations were independent of response latencies and were larger for more emotionally ambiguous vocalisations. No effects of context were found for arousal ratings. These findings suggest that the automatic encoding of contextual information during emotion perception generalises across modalities, to purely non-verbal vocalisations, and is not confined to acted expressions.

Despite health benefits of physical activity (PA) and risks of physical inactivity, many older adults do not accumulate sufficient levels of PA to achieve associated health benefits. Lack of PA enjoyment may be a barrier to PA participation. Combining simulated laughter and PA for strength, balance, and flexibility is a potential solution for helping older adults maintain independence in activities of daily living through enjoyable participation in PA. The purpose of this study is to assess whether combining simulated laughter exercises with a moderate-intensity strength, balance, and flexibility PA program (i.e., LaughActive) increases participation in PA, health, and self-efficacy for PA among older adults residing in 4 assisted living facilities (ALFs). The 12-week wait list control pilot study used pre- and 6-week post-intervention comparisons within and between groups identified by paired sample t-test results among those who participated in twice-weekly LaughActive classes (n = 27). Significant improvements (p < .05-.10) were observed in mental health (SF-36v2), aerobic endurance (2-minute step test), and self-efficacy for exercise (OEE). PA programs that elicit positive emotions through simulated laughter have the potential to improve health, physical performance, and self-efficacy for PA among older adults and may positively influence participant adherence. © The Author 2016.

Humor and laughter in patients with cerebellar degeneration.

PubMed

Frank, B; Propson, B; Göricke, S; Jacobi, H; Wild, B; Timmann, D

2012-06-01

Humor is a complex behavior which includes cognitive, affective and motor responses. Based on observations of affective changes in patients with cerebellar lesions, the cerebellum may support cerebral and brainstem areas involved in understanding and appreciation of humorous stimuli and expression of laughter. The aim of the present study was to examine if humor appreciation, perception of humorous stimuli, and the succeeding facial reaction differ between patients with cerebellar degeneration and healthy controls. Twenty-three adults with pure cerebellar degeneration were compared with 23 age-, gender-, and education-matched healthy control subjects. No significant difference in humor appreciation and perception of humorous stimuli could be found between groups using the 3 Witz-Dimensionen Test, a validated test asking for funniness and aversiveness of jokes and cartoons. Furthermore, while observing jokes, humorous cartoons, and video sketches, facial expressions of subjects were videotaped and afterwards analysed using the Facial Action Coding System. Using depression as a covariate, the number, and to a lesser degree, the duration of facial expressions during laughter were reduced in cerebellar patients compared to healthy controls. In sum, appreciation of humor appears to be largely preserved in patients with chronic cerebellar degeneration. Cerebellar circuits may contribute to the expression of laughter. Findings add to the literature that non-motor disorders in patients with chronic cerebellar disease are generally mild, but do not exclude that more marked disorders may show up in acute cerebellar disease and/or in more specific tests of humor appreciation.

Background Pseudobulbar affect (PBA) is prevalent in amyotrophic lateral sclerosis (ALS), but there is limited information on its associations and course. Objectives Explore prevalence, associations, course and manifestations of PBA in outpatient cohort of patients with ALS and examine its relationship to depression. Methods Self-reported measures of PBA and depression (Center for Neurologic Study-Lability Scale (CNS-LS) and Patient Health Questionnaire (PHQ-9), respectively) were obtained from consecutive patients with ALS using tablet devices in waiting rooms (Knowledge Program). Results PBA (CNS-LS ≥13) was seen in 209/735 patients (28.4%). PBA was associated with bulbar onset and dysfunction, upper motor neuron dysfunction, cognitive impairment, depression and lower quality of life. A multivariable model that included lower bulbar and gross motor subscores, female gender, younger age and shorter duration of disease predicted PBA with 74% accuracy. CNS-LS scores increased only slowly with time. Women with PBA reported more crying than men. Crying (but not laughter) correlated with depression, and crying was associated with poorer quality of life. Exploratory factor analysis of pooled questions of CNS-LS and PHQ-9 identified three underlying factors (laughter, crying and depression) loaded on appropriate questions of the respective instruments. Conclusion This study identifies associations of PBA and additionally finds PBA (especially crying-predominant PBA) more prevalent in women with ALS. Although the two self-report instruments (CNS-LS and PHQ-9) discriminate well between PBA and depression, there is significant overlap between depression and crying in PBA. Studies of PBA should stratify for gender, examine crying and laughter as separate outcomes and adjust for depression. PMID:28572273

Detecting paralinguistic events in audio stream using context in features and probabilistic decisions☆

Non-verbal communication involves encoding, transmission and decoding of non-lexical cues and is realized using vocal (e.g. prosody) or visual (e.g. gaze, body language) channels during conversation. These cues perform the function of maintaining conversational flow, expressing emotions, and marking personality and interpersonal attitude. In particular, non-verbal cues in speech such as paralanguage and non-verbal vocal events (e.g. laughters, sighs, cries) are used to nuance meaning and convey emotions, mood and attitude. For instance, laughters are associated with affective expressions while fillers (e.g. um, ah, um) are used to hold floor during a conversation. In this paper we present an automatic non-verbal vocal events detection system focusing on the detect of laughter and fillers. We extend our system presented during Interspeech 2013 Social Signals Sub-challenge (that was the winning entry in the challenge) for frame-wise event detection and test several schemes for incorporating local context during detection. Specifically, we incorporate context at two separate levels in our system: (i) the raw frame-wise features and, (ii) the output decisions. Furthermore, our system processes the output probabilities based on a few heuristic rules in order to reduce erroneous frame-based predictions. Our overall system achieves an Area Under the Receiver Operating Characteristics curve of 95.3% for detecting laughters and 90.4% for fillers on the test set drawn from the data specifications of the Interspeech 2013 Social Signals Sub-challenge. We perform further analysis to understand the interrelation between the features and obtained results. Specifically, we conduct a feature sensitivity analysis and correlate it with each feature's stand alone performance. The observations suggest that the trained system is more sensitive to a feature carrying higher discriminability with implications towards a better system design. PMID:28713197

French Crossings: II. Laughing Over Boundaries

PubMed Central

Jones, Colin

2016-01-01

Under the generic title, ‘French Crossings’, this Presidential Address explores the history of laughter in French society, and humour’s potential for trangressing boundaries. It focuses on the irreverent and almost entirely unknown book of comic drawings entitled Livre de caricatures tant Bonnes que mauvaises (Book of Caricatures, both Good and Bad), that was composed between the 1740s and the mid-1770s by the luxury Parisian embroiderer and designer, Charles-Germain de Saint-Aubin, and his friends and family. The bawdy laughter that the book seems intended to provoke gave it its nickname of the Livre de culs (Book of Arses). Yet despite the scatological character of many of the drawings, the humour often conjoined lower body functions with rather cerebral and erudite wit. The laughter provoked unsparingly targeted and exposed to ridicule the social elite, cultural celebrities and political leaders of Ancien Regime France. This made it a dangerous object, which was kept strictly secret. Was this humour somehow pre- or proto-Revolutionary? In fact, the work is so embedded in the culture of the Ancien Regime that 1789 was one boundary that the work signally fails to cross. PMID:27630375

Prefrontal mediation of emotion regulation in social anxiety disorder during laughter perception.

Social anxiety disorder (SAD) is characterized by negatively biased perception of social cues and deficits in emotion regulation. While negatively biased perception is thought to maintain social anxiety, emotion regulation represents an ability necessary to overcome both biased perception and social anxiety. Here, we used laughter as a social threat in a functional magnetic resonance imaging (fMRI) study to identify cerebral mediators linking SAD with attention and interpretation biases and their modification through cognitive emotion regulation in the form of reappraisal. We found that reappraisal abolished the negative laughter interpretation bias in SAD and that this process was directly mediated through activation patterns of the left dorsolateral prefrontal cortex (DLPFC) serving as a cerebral pivot between biased social perception and its normalization through reappraisal. Connectivity analyses revealed reduced prefrontal control over threat-processing sensory cortices (here: the temporal voice area) during cognitive emotion regulation in SAD. Our results indicate a central role for the left DLPFC in SAD which might represent a valuable target for future research on interventions either aiming to directly modulate cognitive emotion regulation in SAD or to evaluate its potential as physiological marker for psychotherapeutic interventions relying on emotion regulation.

Pathological laughter and crying: A case series and proposal for a new classification.

2016-02-01

Disorders of laughter and crying (DLC) are seen in several neuropsychiatric conditions. Their nomenclature remains under debate. We present the clinical and imaging findings of 17 patients with DLC and introduce a new classification based on phenomenology and pathogenesis. According to intensity and frequency of laughter and crying (observed behavioral output), patients were divided into hypoactive or hyperactive DLC and subdivided into 5 subtypes: sensory (positive and negative), motor (positive and negative), and mixed. The sensory subtype is represented by disorders of "feeling processing," whereas the motor subtype is represented by disorders of "emotion processing." "Positive" and "negative" describe elicitation by irritative vs destructive lesions, respectively. Among the patients studied, DLC resulted from ischemic stroke (n = 12), intracerebral hemorrhage (n = 2), gunshot wound (n = 1), amyotrophic lateral sclerosis (n = 1), or vestibular migraine (n = 1). Ten patients had lesions in the brainstem, 4 in the cerebral hemispheres, and 2 in sub-cortical-diencephalic structures. Six patients had negative motor DLC, 5 had positive sensory DLC, 4 had negative sensory DLC, and 2 had positive motor DLC. Phenomenology changed or progressed to mixed DLC in 7 patients. This novel phenomenological and pathomechanistic nomenclature explains all subtypes of DLC in neurologic, medical, and psychiatric conditions. Future studies are needed to validate it prospectively.

Pseudobulbar affect: the spectrum of clinical presentations, etiologies and treatments.

PubMed

Miller, Ariel; Pratt, Hillel; Schiffer, Randolph B

2011-07-01

Pseudobulbar affect (PBA) consists of uncontrollable outbursts of laughter or crying inappropriate to the patient's external circumstances and incongruent with the patient's internal emotional state. Recent data suggest disruption of cortico-pontine-cerebellar circuits, reducing the threshold for motor expression of emotion. Disruption of the microcircuitry of the cerebellum itself may likewise impair its ability to act as a gate-control for emotional expression. Current evidence also suggests that serotonergic and glutamatergic neurotransmission play key roles. Although antidepressants have shown benefit, the supportive clinical data have often derived from small numbers of patients and unvalidated measures of PBA severity. Dextromethorphan/quinidine, the first FDA-approved PBA medication, is a novel therapy with antiglutamatergic actions. As life expectancy lengthens and the neurologic settings of PBA become more common, the need for treatment can be expected to increase.

To describe the motor pattern of cataplexy and to determine its phenomenological differences from pseudocataplexy in the differential diagnosis of episodic falls. We selected 30 video-recorded cataplexy and 21 pseudocataplexy attacks in 17 and 10 patients evaluated for suspected narcolepsy and with final diagnosis of narcolepsy type 1 and conversion disorder, respectively, together with self-reported attacks features, and asked expert neurologists to blindly evaluate the motor features of the attacks. Video documented and self-reported attack features of cataplexy and pseudocataplexy were contrasted. Video-recorded cataplexy can be positively differentiated from pseudocataplexy by the occurrence of facial hypotonia (ptosis, mouth opening, tongue protrusion) intermingled by jerks and grimaces abruptly interrupting laughter behavior (i.e. smile, facial expression) and postural control (head drops, trunk fall) under clear emotional trigger. Facial involvement is present in both partial and generalized cataplexy. Conversely, generalized pseudocataplexy is associated with persistence of deep tendon reflexes during the attack. Self-reported features confirmed the important role of positive emotions (laughter, telling a joke) in triggering the attacks, as well as the more frequent occurrence of partial body involvement in cataplexy compared with pseudocataplexy. Cataplexy is characterized by abrupt facial involvement during laughter behavior. Video recording of suspected cataplexy attacks allows the identification of positive clinical signs useful for diagnosis and, possibly in the future, for severity assessment.

Effect of laughter on salivary flow rates and levels of chromogranin A in young adults and elderly people.

PubMed

Toda, Masahiro; Ichikawa, Hiroe

2012-11-01

Salivary chromogranin A (CgA) levels and salivary flow rates were measured to evaluate the stress relief effect of laughter on the young and the elderly. Thirty healthy volunteers (15 aged 20-25 years; 15 aged 62-83 years) performed a serial arithmetic task for 15 min and then watched a comedy video for 30 min. On a different day, as a control, they watched a non-humorous video after performing a task similar to the first one. Saliva samples were collected immediately before and after the arithmetic task, 30 min after completing the task (immediately after watching the film), and 30 min after watching the film (60 min after completing mental task). Salivary CgA levels were determined by enzyme-linked immunosorbent assay. In the elderly group, salivary flow rates, which had declined by the end of the arithmetic task, were statistically significantly higher after watching the comedy video. In the young group, salivary CgA levels, which had increased by the end of the task, had statistically significantly declined after watching the comedy video. No such post-task changes were apparent in control results; in the young group, there was a statistically significant interprotocol difference in salivary CgA levels. These findings suggest that laughter may relieve stress, particularly in the young people.

Assessing Dispositions Toward Ridicule and Laughter in the Workplace: Adapting and Validating the PhoPhiKat-9 Questionnaire

Hofmann, Jennifer; Ruch, Willibald; Proyer, René T.; Platt, Tracey; Gander, Fabian

2017-01-01

The current paper addresses the measurement of three dispositions toward ridicule and laughter; i.e., gelotophobia (the fear of being laughed at), gelotophilia (the joy of being laughed at), and katagelasticism (the joy of laughing at others). These traits explain inter-individual differences in responses to humor, laughter, and social situations related to humorous encounters. First, an ultra-short form of the PhoPhiKat-45 (Ruch and Proyer, 2009) was adapted in two independent samples (Construction Sample N = 157; Replication Sample N = 1,774). Second, we tested the validity of the PhoPhiKat-9 in two further independent samples. Results showed that the psychometric properties of the ultra-short form were acceptable and the proposed factor structure could be replicated. In Validation Sample 1 (N = 246), we investigated the relation of the three traits to responses in a ridicule and teasing scenario questionnaire. The results replicated findings from earlier studies by showing that gelotophobes assigned the same emotions to friendly teasing and malicious ridicule (predominantly low joy, high fear, and shame). Gelotophilia was mainly predicted by relating joy to both, teasing and ridicule scenarios, while katagelasticism was predicted by assigning joy and contempt to ridicule scenarios. In Validation Sample 2 (N = 1,248), we investigated whether the fear of being laughed at is a vulnerability at the workplace: If friendly teasing and laughter of co-workers, superiors, or customers are misperceived as being malicious, individuals may feel less satisfied and more stressed. The results from a representative sample of Swiss employees showed that individuals with a fear of being laughed at are generally less satisfied with life and work and experience more work stress. Moreover, gelotophilia went along with positive evaluations of one's life and work, while katagelasticism was negatively related to work satisfaction and positively related to work stress. In order to establish good work practices and build procedures against workplace bullying, one needs to consider that individual differences impact on a person's perception of being bullied and assessing the three dispositions may give important insights into team processes.

Cataplexy leading to the diagnosis of Niemann-Pick disease type C.

PubMed

Smit, Liesbeth S; Lammers, Gert Jan; Catsman-Berrevoets, Coriene E

2006-07-01

Cataplexy in childhood is a rare and often misdiagnosed symptom. It is described as a brief episode of bilateral loss of muscle tone with intact consciousness, triggered by a variety of strong emotions and in particular with unexpected laughter. This report presents a 9-year old male with progressive cerebellar and pyramidal symptoms and a cognitive decline since the age of 4. His recently developed "drop attacks" on laughter were recognized as cataplexy and led to the diagnosis of Niemann-Pick type C disease. With biochemical studies this diagnosis, a lysosomal storage disease, was confirmed. With cataplexy narcolepsy, Niemann-Pick type C disease, Norrie disease, Prader-Willi syndrome, and Coffin-Lowry syndrome are associated disorders. Recognition of cataplexy in children with concomitant neurologic symptoms may lead to an early and straight diagnosis of one of these disorders.

The capacity to predict what should happen next and to minimize any discrepancy between an expected and an actual sensory input (prediction error) is a central aspect of perception. Particularly in vocal communication, the effective prediction of an auditory input that informs the listener about the emotionality of a speaker is critical. What is currently unknown is how the perceived valence of an emotional vocalization affects the capacity to predict and detect a change in the auditory input. This question was probed in a combined event-related potential (ERP) and time-frequency analysis approach. Specifically, we examined the brain response to standards (Repetition Positivity) and to deviants (Mismatch Negativity - MMN), as well as the anticipatory response to the vocal sounds (pre-stimulus beta oscillatory power). Short neutral, happy (laughter), and angry (growls) vocalizations were presented both as standard and deviant stimuli in a passive oddball listening task while participants watched a silent movie and were instructed to ignore the vocalizations. MMN amplitude was increased for happy compared to neutral and angry vocalizations. The Repetition Positivity was enhanced for happy standard vocalizations. Induced pre-stimulus upper beta power was increased for happy vocalizations, and predicted the modulation of the standard Repetition Positivity. These findings indicate enhanced sensory prediction for positive vocalizations such as laughter. Together, the results suggest that positive vocalizations are more effective predictors in social communication than angry and neutral ones, possibly due to their high social significance.

Handgrip force responses to infant signals were examined in a sample of 43 maltreating and 40 non-maltreating mothers. During a standardized handgrip paradigm, mothers were asked to squeeze a handgrip dynamometer at maximal and at half of their maximal handgrip strength while listening to infant crying and laughter sounds. Maltreating mothers used excessive force more often while listening to infant crying and laughter than non-maltreating mothers. Of the maltreating mothers, only neglectful mothers (n=20) tended to use excessive force more often during crying than non-maltreating mothers. Participants did not rate the sounds differently, indicating that maltreating mothers cannot be differentiated from non-maltreating mothers based on their perception of infant signals, but show different behavioral responses to the signals. Results imply that, in response to infant signals (i.e., crying or laughing), maltreating mothers may be insufficiently able to regulate the exertion of physical force. Copyright © 2014 Elsevier Ltd.

Background We performed an observational study of laughter during seminaturalistic conversations between patients with dementia and familial caregivers. Patients were diagnosed with (1) behavioural variant fronto-temporal dementia (bvFTD), (2) right temporal variant frontotemporal dementia (rtFTD), (3) semantic variant of primary progressive aphasia (svPPA), (4) non-fluent variant primary progressive aphasia (nfvPPA) or (5) early onset Alzheimer’s disease (eoAD). We hypothesised that those with bvFTD would laugh less in response to their own speech than other dementia groups or controls, while those with rtFTD would laugh less regardless of who was speaking. Methods Patients with bvFTD (n=39), svPPA (n=19), rtFTD (n=14), nfvPPA (n=16), eoAD (n=17) and healthy controls (n=156) were recorded (video and audio) while discussing a problem in their relationship with a healthy control companion. Using the audio track only, laughs were identified by trained coders and then further classed by an automated algorithm as occurring during or shortly after the participant’s own vocalisation (‘self’ context) or during or shortly after the partner’s vocalisation (‘partner’ context). Results Individuals with bvFTD, eoAD or rtFTD laughed less across both contexts of self and partner than the other groups. Those with bvFTD laughed less relative to their own speech compared with healthy controls. Those with nfvPPA laughed more in the partner context compared with healthy controls. Conclusions Laughter in response to one’s own vocalisations or those of a conversational partner may be a clinically useful measure in dementia diagnosis. PMID:28235777

Nonlinear Dynamics, Artificial Cognition and Galactic Export

NASA Astrophysics Data System (ADS)

Rössler, Otto E.

2004-08-01

The field of nonlinear dynamics focuses on function rather than structure. Evolution and brain function are examples. An equation for a brain, described in 1973, is explained. Then, a principle of interactional function change between two coupled equations of this type is described. However, all of this is not done in an abstract manner but in close contact with the meaning of these equations in a biological context. Ethological motivation theory and Batesonian interaction theory are reencountered. So is a fairly unknown finding by van Hooff on the indistinguishability of smile and laughter in a single primate species. Personhood and evil, two human characteristics, are described abstractly. Therapies and the question of whether it is ethically allowed to export benevolence are discussed. The whole dynamic approach is couched in terms of the Cartesian narrative, invented in the 17th century and later called Enlightenment. Whether or not it is true that a "second Enlightenment" is around the corner is the main question raised in the present paper.

Laughter is not always funny: breath-holding spells in familial dysautonomia.

PubMed

Maayan, Channa; Katz, Eliot; Begin, Michal; Yuvchev, Ivelin; Kharasch, Virginia S

2015-02-01

Familial dysautonomia (FD) is a genetic disease characterized by primary autonomic dysfunction including parasympathetic hypersensitivity. Breath-holding spells (BHS) are believed to be caused by autonomic dysregulation mediated via the vagus nerve and increased in patients with a family history of BHS. Details and understanding of its pathophysiology are lacking. In this retrospective study of patients with FD, the incidence of BHS was higher at 53.3%, compared with previous studies in normal children. Laughter as a precipitating factor for BHS has not been previously reported in FD and occurred in 10% of patients in this study. Lower lung volumes, chronic lung disease, chronic CO2 retention, and inadequate autonomic compensation occur in those with FD leading to a higher incidence and severity of BHS when crying or laughing. Thus, FD may be a good model for understanding manifestations of the autonomic nervous system dysfunction and contribute to our knowledge of BHS mechanisms. © The Author(s) 2014.

Laughter catches attention!

PubMed

Pinheiro, Ana P; Barros, Carla; Dias, Marcelo; Kotz, Sonja A

2017-12-01

In social interactions, emotionally salient and sudden changes in vocal expressions attract attention. However, only a few studies examined how emotion and attention interact in voice processing. We investigated neutral, happy (laughs) and angry (growls) vocalizations in a modified oddball task. Participants silently counted the targets in each block and rated the valence and arousal of the vocalizations. A combined event-related potential and time-frequency analysis focused on the P3 and pre-stimulus alpha power to capture attention effects in response to unexpected events. Whereas an early differentiation between emotionally salient and neutral vocalizations was reflected in the P3a response, the P3b was selectively enhanced for happy voices. The P3b modulation was predicted by pre-stimulus frontal alpha desynchronization, and by the perceived pleasantness of the targets. These findings indicate that vocal emotions may be differently processed based on task relevance and valence. Increased anticipation and attention to positive vocal cues (laughter) may reflect their high social relevance. Copyright © 2017 Elsevier B.V. All rights reserved.

2016-02-01

Working with different forms of artistic and cultural expressions has been considered a form of health intervention to enhance the understanding and thinking about the needs in this field. A group of clown doctors conducted home visits for eight months to ten families located in micro areas of two family health teams. The practice aimed at expanding the solvability of the care given to people and to communities through the intense proximity established by the art of clownery. The idea consisted of making interventions in the homes of socially vulnerable families indicated by the family health teams using joy, humor, and laughter to stimulate reflections on the daily problems. The presence of "clown doctors" in the houses built strong and free bonds with the families and enhanced the humanized and comprehensive care within the context of family health strategy. Clowns and families found a special way to find possible solutions to the difficulties faced on a daily basis. Male and female clowns were able to manage new subjective constructions for each family to deal with everyday situations.

Infant Humor Perception from 3- to 6-months and Attachment at One Year

PubMed Central

Mireault, Gina; Sparrow, John; Poutre, Merlin; Perdue, Brittany; Macke, Laura

2012-01-01

Infancy is a critical time for the development of secure attachment, which is facilitated by emotionally synchronous interactions with parents. Humor development, which includes shared laughter and joint attention to an event, emerges concurrently with attachment, but little is known regarding the relationship, if any, between humor development and attachment in the first year. Thirty 3-month-old infants were videoed at home each month until they were 6-months old while their parents attempted to amuse them. Frequency of infants’ smiles and laughs served as a measure of “state humor”, and the smiling/laughing subscale of the Infant Behavior Questionnaire-Revised served as a measure of “trait humor”. State and trait humor were not correlated. Lower trait humor as 6 months predicted higher attachment security on the Attachment Q-sort at 12-months (r=. 46), suggesting that less good-humored infants elicit greater parental engagement, which works to the benefit of attachment, or vice versa. Future studies should examine the importance of smiling and laughter as they relate to other developmental phenomena in the first year. PMID:22982281

How does psychopathy relate to humor and laughter? Dispositions toward ridicule and being laughed at, the sense of humor, and psychopathic personality traits.

PubMed

Proyer, René T; Flisch, Rahel; Tschupp, Stefanie; Platt, Tracey; Ruch, Willibald

2012-01-01

This scoping study examines the relation of the sense of humor and three dispositions toward ridicule and being laughed at to psychopathic personality traits. Based on self-reports from 233 adults, psychopathic personality traits were robustly related to enjoying laughing at others, which most strongly related to a manipulative/impulsive lifestyle and callousness. Higher psychopathic traits correlated with bad mood and it existed independently from the ability of laughing at oneself. While overall psychopathic personality traits existed independently from the sense of humor, the facet of superficial charm yielded a robust positive relation. Higher joy in being laughed at also correlated with higher expressions in superficial charm and grandiosity while fearing to be laughed at went along with higher expressions in a manipulative life-style. Thus, the psychopathic personality trait could be well described in its relation to humor and laughter. Implications of the findings are highlighted and discussed with respect to the current literature. Copyright © 2012 Elsevier Ltd. All rights reserved.

The neuropeptide oxytocin plays an important role in social behavior, parenting, and affectionate touch and there is some evidence that oxytocin release can be stimulated by massage or affectionate touch. We examined the effects of massage applied by a massage seat cover on salivary oxytocin levels in two exploratory studies using within-subject designs. In Study 1 massage effects on oxytocin levels were examined in a sample of N=20 healthy female participants. Effects of a 15-min massage session were compared to a control condition during which participants sat on a comfortable chair without a massage seat cover. Salivary oxytocin levels were measured at baseline and up to three hours after the session. We found that massage attenuated oxytocin decreases over time, indicating that massage stimulates oxytocin release. In Study 2, we examined whether effects of massage in N=46 healthy male participants depend on experiences of emotional maltreatment. In addition, we examined whether enhanced oxytocin levels after massage affect the use of excessive handgrip force in response to infant crying and laughter as measured with a handgrip dynamometer. Our findings show that massage results in elevated oxytocin levels compared to a control condition, but that the effects of massage are dependent on experiences of emotional maltreatment. Men with experiences of emotional maltreatment showed lower oxytocin levels, which did not increase after massage. Furthermore, we found that high oxytocin levels after massage were related to reduced handgrip force during exposure to infant crying and laughter, indicating that massage stimulates a sensitive response to infant signals by stimulating oxytocin release. Although massage did not affect oxytocin levels in individuals with experiences of maltreatment, it reduced the use of handgrip force in response to infant crying and laughter in these individuals. Our findings indicate that emotional maltreatment is associated with atypical responding to stimulation of endogenous oxytocin release. Copyright © 2017 Elsevier Ltd. All rights reserved.

Neural Correlates of Sex/Gender Differences in Humor Processing for Different Joke Types.

PubMed

Chan, Yu-Chen

2016-01-01

Humor operates through a variety of techniques, which first generate surprise and then amusement and laughter once the unexpected incongruity is resolved. As different types of jokes use different techniques, the corresponding humor processes also differ. The present study builds on the framework of the 'tri-component theory of humor,' which details the mechanisms involved in cognition (comprehension), affect (appreciation), and laughter (expression). This study seeks to identify differences among joke types and between sexes/genders in the neural mechanisms underlying humor processing. Three types of verbal jokes, bridging-inference jokes (BJs), exaggeration jokes (EJs), and ambiguity jokes (AJs), were used as stimuli. The findings revealed differences in brain activity for an interaction between sex/gender and joke type. For BJs, women displayed greater activation in the temporoparietal-mesocortical-motor network than men, demonstrating the importance of the temporoparietal junction (TPJ) presumably for 'theory of mind' processing, the orbitofrontal cortex for motivational functions and reward coding, and the supplementary motor area for laughter. Women also showed greater activation than men in the frontal-mesolimbic network associated with EJs, including the anterior (frontopolar) prefrontal cortex (aPFC, BA 10) for executive control processes, and the amygdala and midbrain for reward anticipation and salience processes. Conversely, AJs elicited greater activation in men than women in the frontal-paralimbic network, including the dorsal prefrontal cortex (dPFC) and parahippocampal gyrus. All joke types elicited greater activation in the aPFC of women than of men, whereas men showed greater activation than women in the dPFC. To confirm the findings related to sex/gender differences, random group analysis and within group variance analysis were also performed. These findings help further establish the mechanisms underlying the processing of different joke types for the sexes/genders and provide a neural foundation for a theory of sex/gender differences in humor.

The Effect of Mirthful Laughter on the Human Cardiovascular System

PubMed Central

Miller, Michael; Fry, William F.

2009-01-01

It has become increasingly recognized and more widely acknowledged during the past several decades, that a complex relationship exists between behavior associated with emotion and the human cardiovascular (CV) system. Early studies focused on the interplay between negative emotions and elevated CV risk, an effect that has in large part been attributed to increased adrenergic activity. Thus, a variety of adverse CV effects ranging from sudden cardiac death triggered by natural disasters such as earthquakes to transient myocardial stunning resulting from heightened sympathetic overload have been identified in response to acute emotional distress. In fact, the biologic interplay between emotion and CV health has been greatly enhanced through studies of the vascular endothelium. As the largest organ in humans, the inner blood vessel lining serves as a conduit for the transfer of blood cells, lipids and various nutrients across the lumen to neighboring tissues. Healthy endothelial cells secrete vasoactive chemicals, most notably endothelial-derived relaxing factor or nitric oxide (NO), that effects smooth muscle relaxation and vessel dilation via a cyclic guanosine monophosphate (cGMP) dependent protein kinase signaling pathway. In addition, endothelial derived NO may reduce vascular inflammation by attenuating or inhibiting leukocyte adhesion and subendothelial transmigration as well as decreasing platelet activation via cGMP mediated pathways. Taken together, studying the endothelium provides an exceptional opportunity to advance our understanding of the potentially important interrelationship between emotions and the vasculature. Premised on the identification of physiological and biochemical correlates, the former was demonstrated after intracoronary administration of acetylcholine yielded paradoxical endothelial vasoconstriction in response to mental stress exercises. More recently, the brachial artery reactivity test (BART) has permitted endothelial function to be assessed in a non-invasive manner. In addition to traditional CV risk factors, exposure to negative emotions including mental stress and depression have been associated with reduced endothelial vasoreactivity as measured by BART. Whether mirthful laughter has the opposite effect garnered consideration following the discovery that μ3 opiate receptors were expressed in the vascular endothelium. Because mirthful laughter induces the release of β-endorphins which in turn have high affinity for μ3 opiate receptors, we hypothesize that such positive emotions lead to the direct release of NO and associated biological consequences. Indeed, our studies have demonstrated opposing effects on endothelial vasoreactivity between those previously established (e.g., mental stress induced by negative visual and/ or auditory stimuli) and those induced after mirthful laughter, thereby providing a potential mechanistic link between positive emotions and beneficial effects on the vasculature. This article reviews the relevant physiology and comments on the potentially wider clinical implications in the integration of this process to improve vascular health. PMID:19477604

2010-01-01

Previous research on maternal speech and depression has focused almost exclusively on how depressed mothers talk to their infants and toddlers in the U.S. and U.K., two English-speaking countries. This study considered how depressed Spanish-speaking mothers from a Latin American country talk about their preschool-age children. Five-minute speech samples were provided by 178 Chilean mothers who were asked to talk about their 5½-year-old children to a project psychologist. Maternal depressive symptomatology was measured by the Spanish-language version of the Center for Epidemiologic Studies Depression Scale (CES-D). In multivariate analysis of covariance (MANCOVA), higher maternal depressed mood showed statistically significant associations with the following maternal speech characteristics: more criticisms, less laughter, fewer medium pauses, less positive satisfaction with the child’s behavior or characteristics, a rating of a negative overall relationship with the child, and more crying (suggestive trend). A structural equation model confirmed these findings and found an indirect effect between laughter and criticisms: mothers with higher depressed mood who laughed less criticized their children less. The findings illustrate that depressed mood adversely affects how a group of Chilean mothers speak about their children. PMID:21785514

2013-10-01

This study was conducted to determine the effects of a fall prevention program on falls, physical function, psychological function, and home environmental safety in frail elders living at home in rural communities. The design of this study was a nonequivalent control group pre posttest design. The study was conducted from July to November, 2012 with 30 participants in the experimental group and 30 in the control group. Participants were registered at the public health center of E County. The prevention program on falls consisted of laughter therapy, exercise, foot care and education. The program was provided once a week for 8 weeks and each session lasted 80 minutes. The risk score for falls and depression in the experimental group decreased significantly compared with scores for the control group. Compliance with prevention behavior related to falls, knowledge score on falls, safety scores of home environment, physical balance, muscle strength of lower extremities, and self-efficacy for fall prevention significantly increased in the experimental group compared with the control group. These results suggest that the prevention program on falls is effective for the prevention of falls in frail elders living at home.

When Is Humiliation More Intense? The Role of Audience Laughter and Threats to the Self

PubMed Central

Mann, Liesbeth; Feddes, Allard R.; Leiser, Anne; Doosje, Bertjan; Fischer, Agneta H.

2017-01-01

In personal accounts, humiliation is often reported as a very intense, painful, negative emotion. We report two scenario studies in which we explored two factors that may contribute to the intense character of humiliation: (1) unwanted, negative public exposure, and (2) a threat to central aspects of one's identity. Study 1 (N = 115) assessed emotional reactions to a public insult when an audience responded with either laughter or not and when someone from the audience offered support after the insult or no support was offered. Results showed that the intensity of humiliation increased when people laughed after the insult. However, support offered after the insult had no effect on reported humiliation. Study 2 (N = 99) focused on threats to different self-related values and showed stronger reports of humiliation when central self-related values were threatened than when less central self-related values were threatened. Study 2 also replicated the audience-effect from Study 1, but only when central self-related values were threatened and not when less central self-related values were threatened. Limitations of these studies (e.g., the use of scenarios) and potential avenues for future research, such as the (long-term) consequences of humiliation and humiliation in the context of social media, are discussed.

Unconscious presentation of fearful face modulates electrophysiological responses to emotional prosody.

PubMed

Doi, Hirokazu; Shinohara, Kazuyuki

2015-03-01

Cross-modal integration of visual and auditory emotional cues is supposed to be advantageous in the accurate recognition of emotional signals. However, the neural locus of cross-modal integration between affective prosody and unconsciously presented facial expression in the neurologically intact population is still elusive at this point. The present study examined the influences of unconsciously presented facial expressions on the event-related potentials (ERPs) in emotional prosody recognition. In the experiment, fearful, happy, and neutral faces were presented without awareness by continuous flash suppression simultaneously with voices containing laughter and a fearful shout. The conventional peak analysis revealed that the ERPs were modulated interactively by emotional prosody and facial expression at multiple latency ranges, indicating that audio-visual integration of emotional signals takes place automatically without conscious awareness. In addition, the global field power during the late-latency range was larger for shout than for laughter only when a fearful face was presented unconsciously. The neural locus of this effect was localized to the left posterior fusiform gyrus, giving support to the view that the cortical region, traditionally considered to be unisensory region for visual processing, functions as the locus of audiovisual integration of emotional signals. © The Author 2013.

Pathological Laughter and Crying and Psychiatric Comorbidity After Traumatic Brain Injury.

PubMed

Roy, Durga; McCann, Una; Han, Dingfen; Rao, Vani

2015-01-01

There are limited data regarding the incidence of pathological laughter and crying (PLC) after traumatic brain injury (TBI). This study aimed to identify the occurrence of PLC in the first year after TBI and to determine whether there is a relationship between PLC and other clinical features or demographics. Subjects who sustained a first-time TBI were recruited from acute trauma units and were assessed at 3, 6, and 12 months after TBI. Rates of PLC at 3, 6, and 12 months after TBI were 21.4%, 17.5%, and 15.5%, respectively. Patients with PLC had higher percentages of psychiatric diagnoses, including personality changes, depressive disorders, and mood disorders secondary to a general medical condition, as well as higher rates of posttraumatic stress disorder. Univariate logistic and linear regression analyses indicated a significant association between PLC and scores on the Clinical Anxiety Scale 3 months after TBI and on the Hamilton Depression Rating Scale 12 months after TBI. Individuals who have PLC during the first year after TBI are more likely to have any psychiatric diagnosis as well as higher rates of mood and anxiety symptoms. In addition, PLC in the early TBI period may serve as a predictor of depression and anxiety symptoms at 12 months after TBI.

Pathological laughing, one subgroup of psuedobulbar affect, is known as laughter inappropriate to the patient's external circumstances and unrelated to the patient's internal emotional state. The authors present the case of a 76-year-old woman with no significant medical history who experienced pathological laughing after subarachnoid hemorrhage (SAH) due to rupture of an aneurysm, which was successfully treated with craniotomy for aneurysm clipping. In the acute stage after the operation she suffered from severe vasospasm and resulting middle cerebral artery territory infarction and conscious disturbance. As she regained consciousness she was afflicted by pathological laughing 6 months after the onset of SAH. Her involuntary laughter was inappropriate to the situation and was incongruent with the emotional state, and she could not control by herself. Finally the diagnosis of pathological laughing was made and treatment with sertraline, a selective serotonin reuptake inhibitor (SSRI), effectively cured the symptoms. Her pathological laughing was estimated to be consequence of infarction in the right prefrontal cortex and/or corona radiata, resulting from vasospasm. To the authors' knowledge, this is the first report of pathological laughing after aneurysmal SAH. The authors offer insight into the pathophysiology of this rare phenomenon. Effectiveness of sertraline would widen the treatment modality against pathological laughing.

Brain networks of social action-outcome contingency: The role of the ventral striatum in integrating signals from the sensory cortex and medial prefrontal cortex.

PubMed

2017-10-01

Social interactions can be facilitated by action-outcome contingency, in which self-actions result in relevant responses from others. Research has indicated that the striatal reward system plays a role in generating action-outcome contingency signals. However, the neural mechanisms wherein signals regarding self-action and others' responses are integrated to generate the contingency signal remain poorly understood. We conducted a functional MRI study to test the hypothesis that brain activity representing the self modulates connectivity between the striatal reward system and sensory regions involved in the processing of others' responses. We employed a contingency task in which participants made the listener laugh by telling jokes. Participants reported more pleasure when greater laughter followed their own jokes than those of another. Self-relevant listener's responses produced stronger activation in the medial prefrontal cortex (mPFC). Laughter was associated with activity in the auditory cortex. The ventral striatum exhibited stronger activation when participants made listeners laugh than when another did. In physio-physiological interaction analyses, the ventral striatum showed interaction effects for signals extracted from the mPFC and auditory cortex. These results support the hypothesis that the mPFC, which is implicated in self-related processing, gates sensory input associated with others' responses during value processing in the ventral striatum.

Most research into the neural mechanisms of humor has not explicitly focused on the association between emotion and humor on the brain white matter networks mediating this connection. However, this connection is especially salient in gelotophobia (the fear of being laughed at), which is regarded as the presentation of humorlessness, and two related traits, gelotophilia (the enjoyment of being laughed at) and katagelasticism (the enjoyment of laughing at others). Here, we explored whether the topological properties of white matter networks can account for the individual differences in the laughter-related traits of 31 healthy adults. We observed a significant negative correlation between gelotophobia scores and the clustering coefficient, local efficiency and global efficiency, but a positive association between gelotophobia scores and path length in the brain's white matter network. Moreover, the current study revealed that with increasing individual fear of being laughed at, the linking efficiencies in superior frontal gyrus, anterior cingulate cortex, parahippocampal gyrus, and middle temporal gyrus decreased. However, there were no significant correlations between either gelotophilia or katagelasticism scores or the topological properties of the brain white matter network. These findings suggest that the fear of being laughed at is directly related to the level of local and global information processing of the brain network, which might provide new insights into the neural mechanisms of the humor information processing.

I Think We're Alone Now: Solitary Social Behaviors in Adolescents with Autism Spectrum Disorder.

PubMed

2017-10-10

Research into emotional responsiveness in Autism Spectrum Disorder (ASD) has yielded mixed findings. Some studies report uniform, flat and emotionless expressions in ASD; others describe highly variable expressions that are as or even more intense than those of typically developing (TD) individuals. Variability in findings is likely due to differences in study design: some studies have examined posed (i.e., not spontaneous expressions) and others have examined spontaneous expressions in social contexts, during which individuals with ASD-by nature of the disorder-are likely to behave differently than their TD peers. To determine whether (and how) spontaneous facial expressions and other emotional responses are different from TD individuals, we video-recorded the spontaneous responses of children and adolescents with and without ASD (between the ages of 10 and 17 years) as they watched emotionally evocative videos in a non-social context. Researchers coded facial expressions for intensity, and noted the presence of laughter and other responsive vocalizations. Adolescents with ASD displayed more intense, frequent and varied spontaneous facial expressions than their TD peers. They also produced significantly more emotional vocalizations, including laughter. Individuals with ASD may display their emotions more frequently and more intensely than TD individuals when they are unencumbered by social pressure. Differences in the interpretation of the social setting and/or understanding of emotional display rules may also contribute to differences in emotional behaviors between groups.

Adaptation of the Infant Behavior Questionnaire-Revised for use in Ethiopia: Expanding cross-cultural investigation of temperament development.

PubMed

Gartstein, Maria A; Bogale, Wolayte; Meehan, Courtney L

2016-11-01

Cross-cultural differences in temperament were evaluated for Ethiopian (N=109) and U.S. (N=109) samples of infants. We anticipated that the Sidama version of the Infant Behavior Questionnaire-Revised (IBQ-R; Gartstein & Rothbart, 2003) developed for use in Ethiopia would demonstrate satisfactory psychometric properties, and hypothesized significant cross-cultural differences in levels of fine-grained temperament characteristics. Interactions between culture, infant age, and sex were also considered. Internal consistency was satisfactory for 13 of the 14 IBQ-R scales (with a somewhat low estimate observed for Duration of Orienting), and an examination of the structure indicated patterns similar to those observed in the US, and elsewhere. Differences between Ethiopia and the US were noted for Activity Level, Distress to Limitations, Fear, Smiling/Laughter, Falling Reactivity, Cuddliness/Affiliation, Sadness, Approach, and Vocal Reactivity. Parents of infants in the US reported higher levels of attributes associated with Surgency/Positive Affectivity (Activity, Smiling/Laughter, Approach Vocal Reactivity), whereas Ethiopian infants' scores were higher for Distress to Limitations and Fear, linked with the over-arching temperament factor of Negative Emotionality; however, US infants received higher ratings on Sadness, also associated with this factor. Higher Falling Reactivity, a regulation-related attribute, was reported for Ethiopian infants, with US babies receiving higher Cuddliness/Affiliation scores. Significant culture*age interactions were observed for Activity and Fear, along with a significant culture*age*sex interaction for Distress to Limitations. Copyright © 2016 Elsevier Inc.

Facial Feedback and Social Input: Effects on Laughter and Enjoyment in Children with Autism Spectrum Disorders.

Helt, Molly S; Fein, Deborah A

2016-01-01

Both social input and facial feedback appear to be processed differently by individuals with autism spectrum disorder (ASD). We tested the effects of both of these types of input on laughter in children with ASD. Sensitivity to facial feedback was tested in 43 children with ASD, aged 8-14 years, and 43 typically developing children matched for mental age (6-14), in order to examine whether children with ASD use bodily feedback as an implicit source of information. Specifically, children were asked to view cartoons as they normally would (control condition), and while holding a pencil in their mouth forcing their smiling muscles into activation (feedback condition) while rating their enjoyment of the cartoons. The authors also explored the effects of social input in children with ASD by investigating whether the presence of a caregiver or friend (companion condition), or the presence of a laugh track superimposed upon the cartoon (laugh track condition) increased the children's self-rated enjoyment of cartoons or the amount of positive affect they displayed. Results showed that the group with ASD was less affected by all three experimental conditions, but also that group differences seemed to have been driven by one specific symptom of ASD: restricted range of affect. The strong relationship between restricted affect and insensitivity to facial feedback found in this study sheds light on the implications of restricted affect for social development in ASD.

Functional flexibility of infant vocalization and the emergence of language

2013-01-01

We report on the emergence of functional flexibility in vocalizations of human infants. This vastly underappreciated capability becomes apparent when prelinguistic vocalizations express a full range of emotional content—positive, neutral, and negative. The data show that at least three types of infant vocalizations (squeals, vowel-like sounds, and growls) occur with this full range of expression by 3–4 mo of age. In contrast, infant cry and laughter, which are species-specific signals apparently homologous to vocal calls in other primates, show functional stability, with cry overwhelmingly expressing negative and laughter positive emotional states. Functional flexibility is a sine qua non in spoken language, because all words or sentences can be produced as expressions of varying emotional states and because learning conventional “meanings” requires the ability to produce sounds that are free of any predetermined function. Functional flexibility is a defining characteristic of language, and empirically it appears before syntax, word learning, and even earlier-developing features presumed to be critical to language (e.g., joint attention, syllable imitation, and canonical babbling). The appearance of functional flexibility early in the first year of human life is a critical step in the development of vocal language and may have been a critical step in the evolution of human language, preceding protosyntax and even primitive single words. Such flexible affect expression of vocalizations has not yet been reported for any nonhuman primate but if found to occur would suggest deep roots for functional flexibility of vocalization in our primate heritage.

2013-12-01

One objective of this study was to assess the effects of laughter on the psychological, immunological and physiological systems of the body. Another objective was to introduce the Laughing Qigong Program (LQP), as a method of standardization for simulated laughter interventions. A randomized, prospective, experimental study of the LQP was conducted in a group of adolescents (n=67) in Taiwan. During study-hall sessions, experimental subjects (n=34) attended the LQP for eight-weeks. Simultaneously, control subjects (n=33) read or did their homework. All subjects were tested before and after the intervention on the following: Rosenberg Self-Esteem scale (RSE), Chinese Humor Scale (CHS) and Face Scale (FS) as psychological markers; saliva cortisol (CS) as an immunological marker; blood pressure (BP), heart rate (HR), and heart rate variability (HRV) as physiological markers of the body's response to stress. Mood states (FS) were measured before/after each LQP session. Mood states (p=.00) and humor (p=.004; p=.003) improved in the experimental group; no significant changes were found in the controls (p=69; p=60). The immunological marker of stress, cortisol levels, decreased significantly for those who participated in the LQP (p=.001), suggesting lower levels of stress after completion of the program. The LQP is a non-pharmacological and cost-effective means to help adolescents mitigate stresses in their everyday life. Copyright © 2013 The Authors. Published by Elsevier Ltd.. All rights reserved.

Abstract Deep brain stimulation (DBS) of the ventral capsule/ventral striatum (VC/VS) is an investigational therapy for treatment-resistant obsessive-compulsive disorder. The ability of VC/VS DBS to evoke spontaneous mirth in patients, often accompanied by smiling and laughter, is clinically well documented. However, the neural correlates of DBS-evoked mirth remain poorly characterized. Patients undergoing VC/VS DBS surgery underwent intraoperative evaluation in which mirth-inducing and non-mirth-inducing stimulation localizations were identified. Using dynamic causal modeling (DCM) for fMRI, the effect of mirth-inducing DBS on functional and effective connectivity among established nodes in limbic cortico-striato-thalamo-cortical (CSTC) circuitry was investigated. Both mirth-inducing and non-mirth-inducing VC/VS DBS consistently resulted (conjunction, global null, family-wise error-corrected P < 0.05) in activation of amygdala, ventral striatum, and mediodorsal thalamus. However, only mirth-inducing DBS resulted in functional inhibition of anterior cingulate cortex. Dynamic causal modeling revealed that mirth-inducing DBS enhanced effective connectivity from anterior cingulate to ventral striatum, while attenuating connectivity from thalamus to ventral striatum relative to non-mirth-inducing stimulation. These results suggest that DBS-evoked mood elevation is accompanied by distinct patterns of limbic thalamocortical connectivity. Using the novel combination of DBS-evoked mood alteration and functional MRI in human subjects, we provide new insights into the network-level mechanisms that influence affect. PMID:27001680

Sensing emotion in voices: Negativity bias and gender differences in a validation study of the Oxford Vocal ('OxVoc') sounds database.

Emotional expressions are an essential element of human interactions. Recent work has increasingly recognized that emotional vocalizations can color and shape interactions between individuals. Here we present data on the psychometric properties of a recently developed database of authentic nonlinguistic emotional vocalizations from human adults and infants (the Oxford Vocal 'OxVoc' Sounds Database; Parsons, Young, Craske, Stein, & Kringelbach, 2014). In a large sample (n = 562), we demonstrate that adults can reliably categorize these sounds (as 'positive,' 'negative,' or 'sounds with no emotion'), and rate valence in these sounds consistently over time. In an extended sample (n = 945, including the initial n = 562), we also investigated a number of individual difference factors in relation to valence ratings of these vocalizations. Results demonstrated small but significant effects of (a) symptoms of depression and anxiety with more negative ratings of adult neutral vocalizations (R2 = .011 and R2 = .008, respectively) and (b) gender differences in perceived valence such that female listeners rated adult neutral vocalizations more positively and infant cry vocalizations more negatively than male listeners (R2 = .021, R2 = .010, respectively). Of note, we did not find evidence of negativity bias among other affective vocalizations or gender differences in perceived valence of adult laughter, adult cries, infant laughter, or infant neutral vocalizations. Together, these findings largely converge with factors previously shown to impact processing of emotional facial expressions, suggesting a modality-independent impact of depression, anxiety, and listener gender, particularly among vocalizations with more ambiguous valence.

Manning, Jimmie

2015-01-01

This essay features typographic analysis of 258 coming-out narratives from 130 diverse lesbian, gay, or bisexual participants. Two typologies of coming-out conversations, one exploring positive communicative behaviors and another exploring negative, are offered. Positive behaviors for all members of the conversation include open communication channels, affirming direct relational statements, laughter and joking, and nonverbal immediacy. Negative behaviors for those coming out included nervous nonverbal behavior, indirectly approaching the topic, and lack of preparation. Negative behaviors for receivers include expressing denial, religious talk, inappropriate questions or comments, shaming statements, and aggressive statements. Future studies and research implications are considered.

Pathological Joking or Witzelsucht Revisited.

PubMed

Granadillo, Elias D; Mendez, Mario F

2016-01-01

Humor, or the perception or elicitation of mirth and funniness, is distinguishable from laughter and can be differentially disturbed by neuropsychiatric disease. The authors describe two patients with constant joking, or Witzelsucht, in the absence of pseudobulbar affect and review the literature on pathological humor. These patients had involvement of frontal structures, impaired appreciation of nonsimple humor, and a compulsion for disinhibited joking. Current neuroscience suggests that impaired humor integration from right lateral frontal injury and disinhibition from orbitofrontal damage results in disinhibited humor, preferentially activating limbic and subcortical reward centers. Additional frontal-subcortical circuit dysfunction may promote pathological joking as a compulsion.

Autogenic training to reduce anxiety in nursing students: randomized controlled trial.

PubMed

Kanji, Nasim; White, Adrian; Ernst, Edzard

2006-03-01

This paper reports a study to determine the effectiveness of autogenic training in reducing anxiety in nursing students. Nursing is stressful, and nursing students also have the additional pressures and uncertainties shared with all academic students. Autogenic training is a relaxation technique consisting of six mental exercises and is aimed at relieving tension, anger and stress. Meta-analysis has found large effect sizes for autogenic trainings intervention comparisons, medium effect sizes against control groups, and no effects when compared with other psychological therapies. A controlled trial with 50 nursing students found that the number of certified days off sick was reduced by autogenic training compared with no treatment, and a second trial with only 18 students reported greater improvement in Trait Anxiety, but not State Anxiety, compared with untreated controls. A randomized controlled trial with three parallel arms was completed in 1998 with 93 nursing students aged 19-49 years. The setting was a university college in the United Kingdom. The treatment group received eight weekly sessions of autogenic training, the attention control group received eight weekly sessions of laughter therapy, and the time control group received no intervention. The outcome measures were the State-Trait Anxiety Inventory, the Maslach Burnout Inventory, blood pressure and pulse rate completed at baseline, 2 months (end of treatment), and 5, 8, and 11 months from randomization. There was a statistically significantly greater reduction of State (P<0.001) and Trait (P<0.001) Anxiety in the autogenic training group than in both other groups immediately after treatment. There were no differences between the groups for the Maslach Burnout Inventory. The autogenic training group also showed statistically significantly greater reduction immediately after treatment in systolic (P<0.01) and diastolic (P<0.05) blood pressure, and pulse rate (P<0.002), than the other two groups. CONCLUSION. Autogenic training has at least a short-term effect in alleviating stress in nursing students.

Making sense of feedback experiences: a multi-school study of medical students' narratives.

Urquhart, Lynn M; Rees, Charlotte E; Ker, Jean S

2014-02-01

Until recently, the perspective of students in the feedback process has been ignored, with strategies for improvement focusing on the tutor and feedback delivery. We employed an original narrative interviewing approach to explore how medical students make sense of their experiences of feedback. A qualitative design was adopted employing three individual and 10 group interviews to elicit narratives of feedback experiences from 53 medical students at three 5-year undergraduate programmes in the UK during 2011. Thematic analysis was undertaken of students' understandings of feedback and of their narratives of positive and negative experiences of feedback at medical school. In addition, thematic and discourse analysis of the linguistic and paralinguistic features of talk within the narratives was conducted. Students typically constructed feedback as a monologic process that happened 'to' them rather than 'with' them. They shared 352 distinct narratives of feedback experiences, which were rich in linguistic and paralinguistic features of talk. Through the analysis of the interplay between the 'whats' and 'hows' of student talk, i.e. emotion, pronominal and metaphoric talk and laughter, we were able to understand how students find meaning in their experiences. Students used laughter as a coping strategy, emotion talk as a means to convince the audience of the impact of feedback, pronominal and metaphoric talk to describe their relationship (often adversarial) with their feedback providers and to communicate feelings that they might otherwise struggle to articulate. This research extends current feedback literature by focusing on medical students' lived experiences of feedback and their emotional impact through narrative. We go on to discuss the educational implications of our findings and to make recommendations for improvement of the feedback process for students, tutors and for institutions. © 2014 John Wiley & Sons Ltd.

Virtuous laughter: we should teach medical learners the art of humor.

PubMed

Oczkowski, Simon

2015-05-11

There is increasing recognition of the stress and burnout suffered by critical care workers. Physicians have a responsibility to teach learners the skills required not only to treat patients, but to cope with the demands of a stressful profession. Humor has been neglected as a strategy to help learners develop into virtuous and resilient physicians. Humor can be used to reduce stress, address fears, and to create effective health care teams. However, there are forms of humor which can be hurtful or discriminatory. In order to maximize the benefits of humor and to reduce its harms, we need to teach and model the effective and virtuous use of humor in the intensive care unit.

Consciousness and body image: lessons from phantom limbs, Capgras syndrome and pain asymbolia.

PubMed Central

Ramachandran, V S

1998-01-01

Words such as 'consciousness' and 'self' actually encompass a number of distinct phenomena that are loosely lumped together. The study of neurological syndromes allows us to explore the neural mechanisms that might underlie different aspects of self, such as body image and emotional responses to sensory stimuli, and perhaps even laughter and humour. Mapping the 'functional logic' of the many different attributes of human nature on to specific neural circuits in the brain offers the best hope of understanding how the activity of neurons gives rise to conscious experience. We consider three neurological syndromes (phantom limbs, Capgras delusion and pain asymbolia) to illustrate this idea. PMID:9854257

A study of storytelling, humour and learning in medicine.

PubMed

Calman, K

2001-01-01

Story telling is a fundamental part of clinical practice. It provides the mechanism by which doctors and patients communicate and understand the meaning of illness and possible ways of dealing with it. Humour is a particular aspect of story telling and, while there are some negative aspects, generally does have a therapeutic benefit. The physiological effects of laughter are considerable. Both story telling and humour are important for learning and are complementary to the more formal learning from text books and lectures. Stories assist in the development of emotional knowledge. The hypothesis of the contagious theory of behaviour change is presented as a way in which ideas are transmitted from one person to another.

Expressive therapies are increasingly incorporated into the management of Parkinson's disease (PD), although there are little objective data assessing their benefits. Develop and study a novel community Improvisation Theater (IT) program for PD in order to improve quality of life. A prospective, rater-blinded, modified cross-over design study of IT for PD. 22 subjects were randomized 1:1 to active-start (AS) or control-start (CS) groups, controlling for age and Hoehn and Yahr stage. Participants were recruited from the Northwestern PD and Movement Disorders Center. 60 min IT sessions were led by The Second City ® faculty weekly for 12 weeks. The primary aim was to assess feasibility, determined as 70% of participants attending at least 75% of the classes. Exploratory data were obtained comparing pre- and post-intervention outcomes using Wilcoxon signed rank test for UPDRS parts I-IV, PDQ-39, and 5 neuro-QoL measures (communication, anxiety, stigma, depression, and wellbeing). All 22 participants completed the study. 21/22 (95%) participants attended at least 80% of the classes. All participants indicated that they would recommend the class to others with PD. 21/22 participants enjoyed the class and felt it was beneficial for their symptoms. A significant improvement pre-to-post intervention was seen with the UPDRS part II ADL measure (mean -1.5, p = 0.019). A novel improvisation program can be well-attended, enjoyable, and improve ADL measures among patients with PD of varying ages and disease severity. Copyright © 2016 Elsevier Ltd.

In 2014, laughter yoga (LY) achieved the intermediate level, tier 2, under the Title III-D Evidence-based Disease Prevention and Health Promotion Program through the Administration on Aging (AOA). Further research is needed to qualify LY under the criteria for the highest tier, tier 3, to assure continued funding for LY classes at senior centers. The study intended to demonstrate further the benefits of LY and to qualify LY as tier 3 under Title III-D. Using a quasi-experimental design, the research team conducted a preintervention/postintervention study in 3 phases. The study was done in a variety of community centers. Phase 1, a pilot phase, was limited to North Carolina, and phase 2 was conducted in multiple states. Phase 3 was held at the North Carolina Area Agency on Aging's annual Volunteer Appreciation meeting. Participants in phases 1 (n = 109) and 2 (n = 247) enrolled in LY classes. Classes were advertised by fliers posted in community and in retirement centers. The ability of participants to participate in a class was based solely on their desire to participate, regardless of age, ability, health status, or physical impairment. Phase 3 (n = 23) was a convenience sample only. All phases were voluntary. The pre- and posttests for all 3 phases were Likert-scale surveys, 10 questions on the Psychological Outcomes of Well-being (POWB) survey. Pulse and other physiological measurements were also assessed pre- and postintervention. Analysis included a t test on each of the 10 POWB and physiological measures for all phases. All 10 POWB measures for phases 1 and 2 showed significant improvements between the pre- and postintervention testing (P < .001). Phase 3, the control, showed no significant improvement. The initial study demonstrated that LY meets the criteria to qualify for tier 3 under the Title III-D Evidence-based Disease Prevention and Health Promotion Program and that a large number of Americans, regardless of age and physical ability, could benefit from LY.

Laughing rats are optimistic.

Rygula, Rafal; Pluta, Helena; Popik, Piotr

2012-01-01

Emotions can bias human decisions- for example depressed or anxious people tend to make pessimistic judgements while those in positive affective states are often more optimistic. Several studies have reported that affect contingent judgement biases can also be produced in animals. The animals, however, cannot self-report; therefore, the valence of their emotions, to date, could only be assumed. Here we present the results of an experiment where the affect-contingent judgement bias has been produced by objectively measured positive emotions. We trained rats in operant Skinner boxes to press one lever in response to one tone to receive a food reward and to press another lever in response to a different tone to avoid punishment by electric foot shock. After attaining a stable level of discrimination performance, the animals were subjected to either handling or playful, experimenter-administered manual stimulation - tickling. This procedure has been confirmed to induce a positive affective state in rats, and the 50-kHz ultrasonic vocalisations (rat laughter) emitted by animals in response to tickling have been postulated to index positive emotions akin to human joy. During the tickling and handling sessions, the numbers of emitted high-frequency 50-kHz calls were scored. Immediately after tickling or handling, the animals were tested for their responses to a tone of intermediate frequency, and the pattern of their responses to this ambiguous cue was taken as an indicator of the animals' optimism. Our findings indicate that tickling induced positive emotions which are directly indexed in rats by laughter, can make animals more optimistic. We demonstrate for the first time a link between the directly measured positive affective state and decision making under uncertainty in an animal model. We also introduce innovative tandem-approach for studying emotional-cognitive interplay in animals, which may be of great value for understanding the emotional-cognitive changes associated with mood disorders.

Continuity of temperament from 6 months (the IBQ) to 5.5 years (the CBQ) was explored in Finnish children (n=231) within the theoretical framework deviced by Rothbart. Activity level, smiling and laughter, distress to limitations and fear showed significant differential homotypic and heterotypic continuity, while soothability and duration of orienting showed significant differential heterotypic continuity. On the level of latent superconstructs, infant positive and negative affectivity accounted for 4.6, 22.3, and 6.0% of the variance in childhood extraversion, effortful control and negative affectivity, respectively. Infant and childhood temperament clustered into profile types named "resilient", "undercontrolled", and "overcontrolled" mirroring ipsative continuity. These findings give empirical credence to Rothbart's theory by replicating and extending previous findings in significant ways.

Empirical categories: sound, facial, eye and body expressions. sound expressions emphasized laughter. Facial expressions communicated satisfaction and happiness. Eye contact with members stood out in visual expressions. The most frequent body expressions were head movements and indistinct touches. nursing care team members use body language to establish rapport with patients, clarify their needs and plan care. The study classified body language characteristics of humanized care, which involves, in addition to technical, non-technical issues arising from nursing communication.

Putative dopamine agonist (KB220Z) attenuates lucid nightmares in PTSD patients: role of enhanced brain reward functional connectivity and homeostasis redeeming joy.

Lucid dreams are frequently pleasant and training techniques have been developed to teach dreamers to induce them. In addition, the induction of lucid dreams has also been used as a way to ameliorate nightmares. On the other hand, lucid dreams may be associated with psychiatric conditions, including Post-Traumatic Stress Disorder (PTSD) and Reward Deficiency Syndrome-associated diagnoses. In the latter conditions, lucid dreams can assume an unpleasant and frequently terrifying character. We present two cases of dramatic alleviation of terrifying lucid dreams in patients with PTSD. In the first case study, a 51-year-old, obese woman, diagnosed with PTSD and depression, had attempted suicide and experienced terrifying lucid nightmares linked to sexual/physical abuse from early childhood by family members including her alcoholic father. Her vivid "bad dreams" remained refractory in spite of 6 months of treatment with Dialectical Behavioral Therapy (DBT) and standard pharmaceutical agents which included prazosin, clonidie and Adderall. The second 39-year-old PTSD woman patient had also suffered from lucid nightmares. The medication visit notes reveal changes in the frequency, intensity and nature of these dreams after the complex putative dopamine agonist KB220Z was added to the first patient's regimen. The patient reported her first experience of an extended period of happy dreams. The second PTSD patient, who had suffered from lucid nightmares, was administered KB220Z to attenuate methadone withdrawal symptoms and incidentally reported dreams full of happiness and laughter. These cases are discussed with reference to the known effects of KB220Z including enhanced dopamine homeostasis and functional connectivity of brain reward circuitry in rodents and humans. Their understanding awaits intensive investigation involving large-population, double-blinded studies.

A study of sound balances for the hard of hearing

NASA Astrophysics Data System (ADS)

Mathers, C. D.

Over a period of years, complaints have been received from television viewers, especially those who are hard of hearing, that background sound (e.g., audience laughter, crowd noise, mood music) is often transmitted at too high a level with respect to speech, so that information essential to the understanding of the program is lost. To consider possible solutions to the problem, a working party was set up representing both broadcasters and organizations for the hard of hearing. At early meetings, it was resolved that a series of subjective tests should be carried out to determine what reduction of background levels would be needed to provide a significant improvement in the intelligibility of television speech for viewers with hearing difficulties. The preparation of test tapes and the analysis of results are given.

Taking a breath of helium gas and then speaking or singing to the class is a favorite demonstration for an introductory physics course, as it usually elicits appreciative laughter, which serves to energize the class session. Students will usually report that the helium speech "raises the frequency" of the voice. A more accurate description of the phenomenon requires that we distinguish between the frequencies of sound produced by the larynx and the filtering of those frequencies by the vocal tract. We will describe here an experiment done by introductory physics students that uses helium speech as a context for learning about the human vocal system and as an application of the standing sound-wave concept. Modern acoustic analysis software easily obtained by instructors for student use allows data to be obtained and analyzed quickly.

In China, Mr. Chang Junjie, a retired middle school principal has personally organized and financed the "Family Planning Retired Cadre's Troupe," which travels around the countryside performing newly written costume operas. In the six years since he first began to organize the troupe, Chang's players have performed more than 1700 times for more than a million people. The operas draw their material from the real life situations faced by farmers and emphasize the importance of family planning by setting good examples. Chang's operas have been well received, and it is not unusual for his audiences to be moved to laughter and tears. Despite his widespread success, Chang is not content with what he has accomplished and is currently organizing a children's opera troupe and seeking ways to make a greater impact on the promotion of family planning.

Sandbox Tectonics As A Teaching Tool

Students are typically introduced to the relative motions of plates and its effects either through text-based descriptions, paper models, or both. However, though students may learn to repeat the description of the effects, many students still do not show a deeper understanding of the process, as shown by examinations of students before and after an introductory geology course (DeLaughter et al, 1998). This is because students are rarely affected by the information on a visceral level; because their preconceptions are never challenged, they never internalize the information as part of their model of how the world works. However, when concepts such as plate motions and their effects are presented to students as part of a tangible, physical experiment, the ideas can have a much greater impact (Carey et al, 1989). The students use the new information to build more complete mental models while learning that such models can and must change in response to new information (Herbert, 2003). When such experiments are performed in a geology class, they afford the students a direct and visceral experience that may enhance the learning process. In this exercise for middle school students, the effects of relative plate motions on overlying sediments are modeled through a simple and inexpensive set of experiments using sand and newspaper. These experiments provide qualitatively the same results as those performed by geologists researching various aspects of faulting and folding (e.g., Horsfield, 1977, Domingez et al., 2000). A secondary benefit of these experiments is that when the students do not pull the papers perfectly the combination of effects can mimic real terrains (e.g., transpressional) very closely. This intrusion of methodological errors can also lead to a lively discussion of how science is done and what the results of an experiment imply, thereby providing a pedagogical benefit as well. Thus students can be shown the effects of relative plate motions in a direct and obvious manner. Because the experiments produce tangible results, the students experience them on a more visceral level and may be able to incorporate the concepts better than they would through a description or computer simulation of the effects (Klosko et al., 2000). And, as the equipment used is very inexpensive, the experiment is well within the means of almost any school system. References Carey, S., R. Evans, M. Honda, E. Jay, C.

Pathological laughing and crying, or pseudobulbar affect (PBA), has been described in patients with neurological disorders such as multiple sclerosis, amyotrophic lateral sclerosis, Alzheimer's disease, stroke, and traumatic brain injury (TBI) since the 19th century (Schiffer 2005). The syndrome is characterized by inappropriate episodes of laughing or crying after minor stimuli. It was first coined a disinhibition of cortical control by Kinnier Wilson in 1924. It was observed in brain disease and seen with mild TBI. It can impair social and occupational function and is largely underrecognized in clinical settings. PBA is usually treated with antidepressants and dopaminergic agents. In this case we treated a military recruit with TBI with Nuedexta-a dextromethorphan/Quinidine derivative with a subsequent decrease in his episodes.

The Role of Humor in Learning Physics: a Study of Undergraduate Students

We all know that they do it, but what do students laugh about when learning science together? Although research has shown that students do use humor when they learn science, the role of humor in science education has received little attention. In this study, undergraduate students' laughter during collaborative work in physics has been investigated. In order to do this, a framework inspired by conversation analysis has been used. Empirical data was drawn from two video-recorded sessions in which first-year engineering students solved physics problems together. The analysis revealed that the students' use of humor was almost exclusively related to physics. Five themes identified summarize the role of humor in the group discussions: Something is obvious, Something is difficult, Something said might be wrong, Something is absurd, and Something said is not within informal norms.

Allergic responses are enhanced by stress, whereas they are reduced by laughter in atopic eczema patients. Emotion with tears decreases plasma IL-6 levels in patients with rheumatoid arthritis. Thus, the effect of emotion with tears on allergic responses in patients with atopic eczema was studied. Sixty patients with atopic eczema having latex allergy viewed both the weather information video and the heart-warming movie, Kramer vs. Kramer. Just before and immediately after viewing each video, allergic responses to latex were measured. Viewing the weather information video did not cause emotion with tears in any patients, and it failed to modulate allergic responses. In contrast, viewing Kramer vs. Kramer caused emotion with tears in 44 of 60 patients, and it reduced allergic skin wheal responses to latex and latex-specific IgE production in them. Emotion with tears reduced allergic responses, and it may be useful in the treatment of allergic diseases.

Daily pleasant or stressful experiences with grown children may contribute to parental well-being. This diary study focused on midlife parents' ( N = 247) reports regarding grown children for 7 days. Nearly all parents (96%) had contact with a child that week via phone, text, or in person. Nearly all parents shared laughter or enjoyable interactions with grown children during the study week. More than half of parents experienced stressful encounters (e.g., child got on nerves) or stressful thoughts about grown children (e.g., worrying, fretting about a problem). Pleasant and stressful experiences with grown children were associated with parents' positive and negative daily moods. A pleasant experience with a grown child the same day as a stressful experience mitigated effects of those stressful experiences on negative mood, however. The findings have implications for understanding intergenerational ambivalence and stress buffering in this tie.

Three Holy Men Get Haircuts: The Semiotic Analysis of a Joke

2016-01-01

This article deals with a typology of 45 techniques of humor that I found when doing research on the mechanisms that generate humor in texts, lists the techniques and applies them to a Jewish joke. It references the work of Vladimir Propp on folktales as analogous in that both are concerned with mechanisms in text that generate meaning. It also deals with four theories about why people find texts humorous, defines the joke as a short narrative with a punch line that is meant to generate mirthful laughter and defines Jewish humor as being about Jewish people and culture as told by Jewish people. It offers a paradigmatic analysis of the joke, and offers some insights into why Jewish people developed their distinctive kind of humor. This article is an enhanced and expanded version of an article which was published in a Chinese semiotics journal (doi:10.1515/css-2015-0022). PMID:27547262

Angelman syndrome with uniparental disomy due to paternal meiosis II nondisjunction.

PubMed

1999-06-01

We report a case of Angelman syndrome (AS) with paternal uniparental disomy (pUPD) of chromosome 15. This 6-year-old girl with overgrowth had frequent, but only provoked laughter, was mildly ataxic with limb hypertonia, and had no intelligible speech. She had deep-set eyes, protruding tongue, and prominent chin. The karyotype was normal. DNA analysis with microsatellites from chromosome 15 showed no inheritance of maternal alleles both within and outside the AS critical region. Proximal markers showed reduction to homozygosity of paternal alleles, intermediate markers showed nonreduction, and distal markers reduction, thus suggesting a meiosis II nondisjunction event in the father with two crossovers. This is, to our knowledge, the first reported case of AS due to meiosis II nondisjunction. We present detailed physical measurements in this patient, adding to the clinical description of the milder phenotype in AS due to pUPD.

Peer Groups as a Context for School Misconduct: The Moderating Role of Group Interactional Style.

Peer group interactional style was examined as a moderator of the relation between peer group school misconduct and group members' school misconduct. Participants were 705 students (M age  = 11.59 years, SD = 1.37) in 148 peer groups. Children reported on their school misconduct in fall and spring. In the winter, group members were observed in a limited-resource task and a group conversation task, and negative and positive group interactional styles were assessed. Multilevel modeling indicated that membership in groups that were higher on school misconduct predicted greater school misconduct only when the groups were high on negative or low on positive interactional style. Results suggest that negative laughter and a coercive interactional style may intensify group effects on children's misconduct. © 2017 The Authors.

No laughing matter: How the presence of laughing witnesses changes the perception of insults.

PubMed

Otten, Marte; Mann, Liesbeth; van Berkum, Jos J A; Jonas, Kai J

Insults always sting, but the context in which they are delivered can make the effects even worse. Here we test how the brain processes insults, and whether and how the neurocognitive processing of insults is changed by the presence of a laughing crowd. Event-related potentials showed that insults, compared to compliments, evoked an increase in N400 amplitude (indicating increased lexical-semantic processing) and LPP amplitude (indicating emotional processing) when presented in isolation. When insults were perceived in the presence of a laughing crowd, the difference in N400 amplitude disappeared, while the difference in LPP activation increased. These results show that even without laughter, verbal insults receive additional neural processing over compliments, both at the lexical-semantic and emotional level. The presence of a laughing crowd has a direct effect on the neurocognitive processing of insults, leading to stronger and more elongated emotional processing.

Bridging the bonding gap: the transition from primates to humans.

PubMed

Dunbar, R I M

2012-07-05

Primate societies are characterized by bonded social relationships of a kind that are rare in other mammal taxa. These bonded relationships, which provide the basis for coalitions, are underpinned by an endorphin mechanism mediated by social grooming. However, bonded relationships of this kind impose constraints on the size of social groups that are possible. When ecological pressures have demanded larger groups, primates have had to evolve new mechanisms to facilitate bonding. This has involved increasing the size of vocal and visual communication repertoires, increasing the time devoted to social interaction and developing a capacity to manage two-tier social relationships (strong and weak ties). I consider the implications of these constraints for the evolution of human social communities and argue that laughter was an early evolutionary innovation that helped bridge the bonding gap between the group sizes characteristic of chimpanzees and australopithecines and those in later hominins.

This interview explores how performing artist, activist, writer, director, performer Adelina Anthony stages queer women of color affects as a complex terrain to mobilize a decolonial imaginary. Anthony's characters are complex, contradictory, surly, and resilient with whom audience members connect and feel deeply. Especially for queer women of color, who rarely get to see their own experiences on film or on stage, Anthony's work provides a critical forum for discussing, imagining, naming, and envisioning the connections between our personal struggles and broader forces of imperialism, heterosexual capitalism, and settler colonialism. Through the "medicina" of gritty truth-telling and side-splitting laughter, Anthony discusses her own positionality as a coyote curandera. Through the exploratory genre of the interview, Anthony helps readers palpably engage a queer woman of color "theory in the flesh" to imagine their own creative potentialities through a compassionate lens of humility and humor.

Effects of noise from non-traffic-related ambient sources on sleep: review of the literature of 1990-2010.

2011-01-01

This article reviews the literature about the effects of specific non-traffic-related ambient noise sources on sleep that appeared in the last two decades. Although everybody is faced with noise of non-traffic and non-industry origin (e.g. sounds made by neighbors, talk, laughter, music, slamming doors, structural equipment, ventilation, heat pumps, noise from animals, barking dogs, outdoor events etc.), little scientific knowledge exists about its effects on sleep. The findings of the present extensive literature search and review are as follows: Only a small number of surveys, laboratory and field studies about mainly neighborhood, leisure and animal noise have been carried out. Most of them indicate that ambient noise has some effect on human sleep. However, a quantitative meta-analysis and comparison is not possible due to the small number of studies available and at times large differences in quality.

Behavior and neuropsychiatric manifestations in Angelman syndrome

PubMed Central

Pelc, Karine; Cheron, Guy; Dan, Bernard

2008-01-01

Angelman syndrome has been suggested as a disease model of neurogenetic developmental condition with a specific behavioral phenotype. It is due to lack of expression of the UBE3A gene, an imprinted gene located on chromosome 15q. Here we review the main features of this phenotype, characterized by happy demeanor with prominent smiling, poorly specific laughing and general exuberance, associated with hypermotor behavior, stereotypies, and reduced behavioral adaptive skills despite proactive social contact. All these phenotypic characteristics are currently difficult to quantify and have been subject to some differences in interpretation. For example, prevalence of autistic disorder is still debated. Many of these features may occur in other syndromic or nonsyndromic forms of severe intellectual disability, but their combination, with particularly prominent laughter and smiling may be specific of Angelman syndrome. Management of problematic behaviors is primarily based on behavioral approaches, though psychoactive medication (eg, neuroleptics or antidepressants) may be required. PMID:18830393

Context matters: the benefits and costs of expressing positive emotion among survivors of childhood sexual abuse.

Positive emotions promote adjustment to aversive life events. However, evolutionary theory and empirical research on trauma disclosure suggest that in the context of stigmatized events, expressing positive emotions might incur social costs. To test this thesis, the authors coded genuine (Duchenne) smiling and laughter and also non-Duchenne smiling from videotapes of late-adolescent and young adult women, approximately half with documented histories of childhood sexual abuse (CSA), as they described the most distressing event of their lives. Consistent with previous studies, genuine positive emotional expression was generally associated with better social adjustment two years later. However, as anticipated, CSA survivors who expressed positive emotion in the context of describing a past CSA experience had poorer long-term social adjustment, whereas CSA survivors who expressed positive emotion while describing a nonabuse experience had improved social adjustment. These findings suggest that the benefits of positive emotional expression may often be context specific.

Background Lucid dreams are frequently pleasant and training techniques have been developed to teach dreamers to induce them. In addition, the induction of lucid dreams has also been used as a way to ameliorate nightmares. On the other hand, lucid dreams may be associated with psychiatric conditions, including Post-Traumatic Stress Disorder (PTSD) and Reward Deficiency Syndrome-associated diagnoses. In the latter conditions, lucid dreams can assume an unpleasant and frequently terrifying character. Case Presentations We present two cases of dramatic alleviation of terrifying lucid dreams in patients with PTSD. In the first case study, a 51-year-old, obese woman, diagnosed with PTSD and depression, had attempted suicide and experienced terrifying lucid nightmares linked to sexual/physical abuse from early childhood by family members including her alcoholic father. Her vivid “bad dreams” remained refractory in spite of 6 months of treatment with Dialectical Behavioral Therapy (DBT) and standard pharmaceutical agents which included prazosin, clonidie and Adderall. The second 39-year-old PTSD woman patient had also suffered from lucid nightmares. Results The medication visit notes reveal changes in the frequency, intensity and nature of these dreams after the complex putative dopamine agonist KB220Z was added to the first patient’s regimen. The patient reported her first experience of an extended period of happy dreams. The second PTSD patient, who had suffered from lucid nightmares, was administered KB220Z to attenuate methadone withdrawal symptoms and incidentally reported dreams full of happiness and laughter. Conclusions These cases are discussed with reference to the known effects of KB220Z including enhanced dopamine homeostasis and functional connectivity of brain reward circuitry in rodents and humans. Their understanding awaits intensive investigation involving large-population, double-blinded studies. PMID:26132915

A qualitative cancer screening study with childhood sexual abuse survivors: experiences, perspectives and compassionate care.

Gesink, Dionne; Nattel, Lilian

2015-08-05

The childhood sexual abuse (CSA) survivor population is substantial and survivors have been identified as part of the population who were under-screened or never-screened for breast, cervical and colon cancer. Our objective was to learn CSA survivor perspectives on, and experiences with, breast, cervical and colon cancer screening with the intention of generating recommendations to help healthcare providers improve cancer screening participation. A pragmatic constructivist qualitative study involving individual, semistructured, in-depth interviews was conducted in January 2014. Thematic analysis was used to describe CSA survivor perspectives on cancer screening and identify potential facilitators for screening. A diverse purposive sample of adult female CSA survivors was recruited. The inclusion criteria were: being a CSA survivor, being in a stable living situation, where stable meant able to meet one's financial needs independently, able to maintain supportive relationships, having participated in therapy to recover from past abuse, and living in a safe environment. 12 survivors were interviewed whose ages ranged from the early 40s to mid-70s. Descriptive saturation was reached after 10 interviews. Interviews were conducted over the phone or Internet. CSA survivors were primarily from urban and rural Ontario, but some resided elsewhere in Canada and the USA. The core concept that emerged was that compassionate care at every level of the healthcare experience could improve cancer screening participation. Main themes included: desire for holistic care; unique needs of patients with dissociative identity disorder; the patient-healthcare provider relationship; appointment interactions; the cancer screening environment; and provider assumptions about patients. Compassionate care can be delivered by: building a relationship; practising respect; focusing attention on the patient; not rushing the appointment; keeping the environment positive and comfortable; maintaining patient dignity; sharing control whenever possible; explaining procedures; and using laughter to reduce power imbalance through shared humanity.

Despite the great advances in chemotherapeutics, infectious diseases are still one of the leading causes of death worldwide. Among some of the clinically relevant pathogens, methicillin-resistant Staphylococcus aureus (MRSA) ranks as one of the most difficult bacteria to treat. It is a common cause of skin, soft-tissue, and endovascular infections, as well as pneumonia, septic arthritis, endocarditis, osteomyelitis, and sepsis. The research on Basidiomycota is extensive; many species show a broad spectrum of pharmacological activities, including antimicrobial activity. The vast majority of the literature to date generally focuses on screening the antibacterial properties of mushroom extracts. A gap still exists in the identification of the individual compounds responsible for these properties, and few low molecular weight compounds have been described. Gymnopilus junonius, the big laughter mushroom, grows wild in Uruguay, especially on Eucalyptus spp. plantations; it is known as the "eucalyptus fungus." In this work, we report the bioguided isolation, structural elucidation, and antistaphylococcal activity of the main antimicrobial components of fresh basidiocarps of G. junonius.

Brain Activity while Reading Sentences with Kanji Characters Expressing Emotions

NASA Astrophysics Data System (ADS)

Yuasa, Masahide; Saito, Keiichi; Mukawa, Naoki

In this paper, we describe the brain activity associated with kanji characters expressing emotion, which are places at the end of a sentence. Japanese people use a special kanji character in brackets at the end of sentences in text messages such as those sent through e-mail and messenger tools. Such kanji characters plays a role to expresses the sender's emotion (such as fun, laughter, sadness, tears), like emoticons. It is a very simple and effective way to convey the senders' emotions and his/her thoughts to the receiver. In this research, we investigate the effects of emotional kanji characters by using an fMRI study. The experimental results show that both the right and left inferior frontal gyrus, which have been implicated on verbal and nonverbal information, were activated. We found that we detect a sentence with an emotional kanji character as the verbal and nonverval information, and a sentence with emotional kanji characters enrich communication between the sender and the reciever.

Central nervous system control of the laryngeal muscles in humans

PubMed Central

Ludlow, Christy L.

2005-01-01

Laryngeal muscle control may vary for different functions such as: voice for speech communication, emotional expression during laughter and cry, breathing, swallowing, and cough. This review discusses the control of the human laryngeal muscles for some of these different functions. Sensori-motor aspects of laryngeal control have been studied by eliciting various laryngeal reflexes. The role of audition in learning and monitoring ongoing voice production for speech is well known; while the role of somatosensory feedback is less well understood. Reflexive control systems involving central pattern generators may contribute to swallowing, breathing and cough with greater cortical control during volitional tasks such as voice production for speech. Volitional control is much less well understood for each of these functions and likely involves the integration of cortical and subcortical circuits. The new frontier is the study of the central control of the laryngeal musculature for voice, swallowing and breathing and how volitional and reflexive control systems may interact in humans.

Does gender make a difference in the way politicians speak and are spoken to in public? This paper examines perspective in three television interviews and two radio interviews with Bill Clinton in June 2004 and in three television interviews and two radio interviews with Hillary Clinton in June 2003 with the same interviewers. Our perspectival approach assumes that each utterance has a dialogically constructed point of view. Earlier research has shown that markers of conceptual orality and literacy as well as referencing (name and pronoun use for self and other reference) do reflect perspective. This paper asks whether perspective is gendered. Our data analysis demonstrates that some markers of perspective show gender differences while others do not. Those that do include the number of syllables spoken by each interlocutor, referencing, the use of the intensifier so, the use of the hedge you know, the use of non-standard pronunciations, turn transitions, and lastly the use of laughter.

Peripherally Restricted Cannabinoids for the Treatment of Pain.

2015-10-01

The use of cannabinoids for the treatment of chronic diseases has increased in the United States, with 23 states having legalized the use of marijuana. Although currently available cannabinoid compounds have shown effectiveness in relieving symptoms associated with numerous diseases, the use of cannabis or cannabinoids is still controversial mostly due to their psychotropic effects (e.g., euphoria, laughter) or central nervous system (CNS)-related undesired effects (e.g., tolerance, dependence). A potential strategy to use cannabinoids for medical conditions without inducing psychotropic or CNS-related undesired effects is to avoid their actions in the CNS. This approach could be beneficial for conditions with prominent peripheral pathophysiologic mechanisms (e.g., painful diabetic neuropathy, chemotherapy-induced neuropathy). In this article, we discuss the scientific evidence to target the peripheral cannabinoid system as an alternative to cannabis use for medical purposes, and we review the available literature to determine the pros and cons of potential strategies that can be used to this end. © 2015 Pharmacotherapy Publications, Inc.

Patterns of Weakness, Classification of Motor Neuron Disease & Clinical Diagnosis of Sporadic ALS

PubMed Central

Statland, Jeffrey M.; Barohn, Richard J.; McVey, April L.; Katz, Jonathan; Dimachkie, Mazen M.

2015-01-01

Synopsis When approaching the patient with suspected motor neuron disease (MND) the pattern of weakness on exam helps distinguish MND from other diseases of peripheral nerves, the neuromuscular junction, or muscle. MND is a clinical diagnosis supported by findings on electrodiagnostic testing, in the absence of other abnormalities on neuroimaging or serological testing. MNDs exist on a spectrum: from a pure lower motor neuron; to mixed upper and lower motor neuron; to a pure upper motor neuron variant in addition to regional variants restricted to the arms, legs or bulbar region. Amyotrophic lateral sclerosis (ALS) is a progressive mixed upper and lower motor neuron disorder, most commonly sporadic (~85%), which is invariably fatal. The only FDA approved treatments for ALS are riluzole, which prolongs life by about 3 months, and dextromethorphan/quinidine which provides symptomatic relief for pseudobulbar affect (inappropriate bouts of laughter or crying). Here we describe a pattern approach to identifying motor neuron disease, and clinical features of sporadic ALS. PMID:26515618

How Was the Weekend? How the Social Context Underlies Weekend Effects in Happiness and Other Emotions for US Workers.

Helliwell, John F; Wang, Shun

2015-01-01

In this paper we estimate the size of weekend effects for seven emotions and then explore their main determinants for the working population in the United States, using the Gallup/Healthways US Daily Poll 2008-2012. We first find that weekend effects exist for all emotions, and that these effects are not explained by sample selection bias. Full-time workers have larger weekend effects than do part-time workers. We then explore the sources of weekend effects and find that workplace trust and workplace social relations, combined with differences in social time spent with family and friends, together almost fully explain the weekend effects for happiness, laughter, enjoyment and sadness, for both full-time and part-time workers, with significant but smaller proportions explained for the remaining three emotions-worry, anger and stress. Finally, we show that workplace trust and social relations significantly improve emotions and life evaluations on both weekends and weekdays for all workers.

Development of mother-infant interaction in tickling play: The relationship between infants' ticklishness and social behaviors.

PubMed

Ishijima, Konomi; Negayama, Koichi

2017-11-01

This study examined the development of mother-infant tickling interaction and the relationship between infants' ticklishness and social behaviors including infants' looking at mothers' face, mothers' narrative tickling, and mothers' laughter. Twenty-two Japanese infants aged 5 months (n=10, five girls) and 7 months (n=12, four girls) and their mothers were videotaped. Results revealed that the mothers' narrative tickling was more frequent at 7 than at 5 months and the infants' strong ticklishness showed the same tendency. The infants' strong ticklishness was linked with the occurrence of other social behaviors. In conclusion, infants' ticklishness was heavily connected with social behaviors. The mode of the tickling interaction at 7 months was different from that at 5 months especially in the increase of mother's narrative tickling. A possible function of such mother's narrative tickling to facilitate infant active communication at a higher cognitive level including anticipation, was discussed. Copyright © 2017 Elsevier Inc.

Why did the proton cross the road? Humour and science communication.

PubMed

Riesch, Hauke

2015-10-01

The use of humour in public discourse about science has grown remarkably over the past few years, and when used in science communication activities is being seen as a great way to bring science to the public through laughter. However, barely any research has been published either on the often-assumed beneficial learning effects of humour in informal science education, or on the wider social functions and effects of humour about science and how humorous public discourse about science can influence the public understanding of science and the science-society relationship. This research note reviews some of the literature on the psychology and sociology of humour and comedy and tries to apply some of its insights to the effects humour might have when used in science communication. Although not intended to be anti-humour, this note attempts at least to start a more critical conversation on the value of humour in the communication of science. © The Author(s) 2014.

The essence of humour and its effects and functions: a qualitative study.

Humour is one of the innate abilities that an individual develops whilst growing up and which is affected by his/her experiences in life. The purpose of this study was to describe which categories can be included in the term 'humour' and to describe the effects and functions that humour has on people. The study was exploratory. The data were based on 20 interviews, nine of which were made with women and 11 with men who had no formal connection to health services or nursing. Ages ranged from 17 to 75 years and all the interviewees were from Sweden. The research question was: 'what does humour mean to you?'. The answers given were labelled as: laughter, happiness, unforeseen events/situations, real humour/art form, jokes, plays on words/puns, situation comedy and political satire. The categories were: possibilities/obstacles and weapon/protection. We conclude that the essence of humour can be categorized as possibilities/obstacles and weapon/protection. Humour has effects and functions on individuals. Empathy is a prerequisite for the use of humour in the context of health services and nursing.

The transformative power of story for healing.

Profeit-LeBlanc, Louise

2003-01-01

One of our goals in this session was, not just to talk about the healing power of narrative, but to experience it as well. Louise Profeit-LeBlanc is one of the presenters we invited specifically because of her skills as a storyteller. She has been heavily involved for several years as both an organizer and a participant in the Yukon Storytelling Festival, held every year in late May in Whitehorse. Woven into her presentation is a useful framework for differentiating various kinds of stories. As she tells us a series of stories, she takes us through a wide range of emotions from grief and loss to laughter and awe. For each of her stories, she gives us some personal contextual information that adds to the story’s meaning and helps us appreciate its significance. Her final story, in particular, is the kind of traditional story that has probably existed for a very long time. Such stories may be told with slightly different emphases, depending on the occasion, but they carry wisdom and value for every generation that hears them.

Neural markers of a greater female responsiveness to social stimuli

Background There is fMRI evidence that women are neurally predisposed to process infant laughter and crying. Other findings show that women might be more empathic and sensitive than men to emotional facial expressions. However, no gender difference in the brain responses to persons and unanimated scenes has hitherto been demonstrated. Results Twenty-four men and women viewed 220 images portraying persons or landscapes and ERPs were recorded from 128 sites. In women, but not in men, the N2 component (210–270) was much larger to persons than to scenes. swLORETA showed significant bilateral activation of FG (BA19/37) in both genders when viewing persons as opposed to scenes. Only women showed a source of activity in the STG and in the right MOG (extra-striate body area, EBA), and only men in the left parahippocampal area (PPA). Conclusion A significant gender difference was found in activation of the left and right STG (BA22) and the cingulate cortex for the subtractive condition women minus men, thus indicating that women might have a greater preference or interest for social stimuli (faces and persons).

Wigs, laughter, and subversion: Charles Busch and strategies of drag performance.

PubMed

Niles, Richard

2004-01-01

This paper examines the strategies of drag performer/ playwright Charles Busch. His performance aesthetic is explored and shown to be subversive even though its initial impulse is to entertain. Basing my arguments on the work of Judith Butler, Elin Diamond, and others, I argue that drag queens like Busch can not only entertain but also make audiences question and criticize through drag's power to create a Brechtian alienation effect and historicize the subject. After showing how he can be viewed as a drag queen, I give a brief biography and discuss such contested terms as "camp" and "gay sensibility." I then focus on Busch's staged reading of Ibsen's Hedda Gahler andA Doll's House, both done in one afternoon at Theatre for The New City (6 May 2000). By examining the performance of Busch and his fellow actors, I demonstrate how a contemporary relevancy is achieved by having the roles played by a female impersonator whose acting choices are filtered through a gay sensibility. The ongoing dialectic between spectator and performer creates a historicized moment in performance that underscores the gender dynamics in unexpected and stimulating ways.

Oxytocin decreases handgrip force in reaction to infant crying in females without harsh parenting experiences.

Infant crying can elicit sensitive caregiving as well as hostility and harsh parenting responses. In the current study (N = 42 females) with a double-blind experimental design, we tested the effect of intranasal oxytocin administration on the use of excessive force using a hand-grip dynamometer during listening to infant cry sounds. Participants' experiences with harsh parental discipline during childhood were found to moderate the effect of oxytocin administration on the use of excessive force. Participants' whose parents did not discipline them harshly used less excessive force in the oxytocin condition, but for participants who were disciplined harshly there was no difference between the oxytocin and placebo condition. Such effects were not found during listening to infant laughter. We conclude that early caregiving experiences constitute an important moderator of the prosocial and/or stress-reducing effects of oxytocin. Oxytocin administration may increase trust and cooperation in individuals with supportive backgrounds, but not generate this effect in individuals who as a consequence of unfavorable early caregiving experiences may have a bias toward negative interpretation of social cues.

Humour between nurse and patient, and among staff: analysis of nurses' diaries.

Astedt-Kurki, P; Isola, A

2001-08-01

The aim of this study was to investigate the occurrence of humour both between nurses and patients and among nursing staff. Humour has positive effects on both a person's physiology and the psyche. Laughter signifies positive things to people; it may add to feelings of togetherness, closeness and friendliness. The use of humour is an indication of mental well-being and it minimizes the effect of negative factors and protects from difficulties. The data consisted of diaries written by nurses (n=16), which were analysed inductively using content analysis. The main categories of humour between nurse and patient were nurse-based humour, co-operation-orientated humour and patient-orientated humour. Humour among staff consisted of the main category of resource-orientated humour. The consequences of humour between nurse and patient enabled them both to cope with various unpleasant procedures. It helped them to manage difficult situations and led to an improvement in the working climate. Humour among staff helped nurses to cope with their work and created a better atmosphere on the ward.

Laughing as a manifestation of rapid eye movement sleep behavior disorder.

Among the range of sleep-related behavior displayed by patients with rapid eye movement (REM) sleep behavior disorder (RBD), aggressive acts are particularly common, while pleasant behaviors have rarely been reported. We aimed at identifying the frequency and characteristics of patients who displayed laughing as a pleasant, nonviolent manifestation of RBD. We reviewed 67 consecutive polysomnographic recordings of patients with RBD, obtained in our sleep laboratory between July 2004 and July 2009. We identified 14 patients (21% of our RBD patients with degenerative parkinsonism: 10 males, mean age 63 ± 11 years) who repeatedly laughed during REM sleep. Ten patients had idiopathic Parkinson's disease, 3 suffered from multisystem atrophy and 1 patient was diagnosed with dementia with Lewy bodies. Other RBD-associated behaviors included smiling, crying, aggressive behavior, screaming, and somniloquia. Nine of the 14 patients were depressed during daytime. Laughing belongs to the spectrum of behavioral manifestations of RBD. Many of our patients with RBD-associated laughter were depressed, suggesting a dissociation between emotional expression during daytime and REM sleep. Copyright © 2011 Elsevier Ltd.

Positive attitude towards life and emotional expression as personality phenotypes for centenarians

2012-01-01

Centenarians have been reported to share particular personality traits including low neuroticism and high extraversion and conscientiousness. Since these traits have moderate to high heritability and are associated with various health outcomes, personality appears linked to bio-genetic mechanisms which may contribute to exceptional longevity. Therefore, the present study sought to detect genetically-based personality phenotypes in a genetically homogeneous sample of centenarians through developing and examining psychometric properties of a brief measure of the personality of centenarians, the Personality Outlook Profile Scale (POPS). The results generated two personality characteristics/domains, Positive Attitude Towards Life (PATL: optimism, easygoing, laughter, and introversion/outgoing) and Emotional Expression (EE: expressing emotions openly and not bottling up emotions). These domains demonstrated acceptable concurrent validity with two established personality measures, the NEO-Five Factor Inventory and Life Orientation Test-Revised. Additionally, centenarians in both groups had lower neuroticism and higher conscientiousness than the US adult population. Findings suggest that the POPS is a psychometrically sound measure of personality in centenarians and capture personality aspects of extraversion, neuroticism, and conscientiousness, as well as dispositional optimism which may contribute to successful aging.

2016-01-01

Animal studies and preliminary clinical trials have shown that cannabidiol (CBD)-enriched extracts may have beneficial effects for children with treatment-resistant epilepsy. However, these compounds are not yet registered as medicines by regulatory agencies. We describe the cases of two children with treatment-resistant epilepsy (Case A with left frontal dysplasia and Case B with Dravet Syndrome) with initial symptom improvement after the introduction of CBD extracts followed by seizure worsening after a short time. The children presented typical signs of intoxication by Δ9-THC (inappropriate laughter, ataxia, reduced attention, and eye redness) after using a CBD-enriched extract. The extract was replaced by the same dose of purified CBD with no Δ9-THC in both cases, which led to improvement in intoxication signs and seizure remission. These cases support pre-clinical and preliminary clinical evidence suggesting that CBD may be effective for some patients with epilepsy. Moreover, the cases highlight the need for randomized clinical trials using high-quality and reliable substances to ascertain the safety and efficacy of cannabinoids as medicines.

Gelastic seizures with dancing arising from the anterior prefrontal cortex.

This case report provides insight into the function of the anterior prefrontal cortex (aPFC), specifically Brodmann Area 10 (BA10), and its interconnectivity. We present a 10-year-old patient with lesional epilepsy and ictal onset, localised to BA10 in the aPFC. Thirty-four seizures were recorded. All seizures involved a demonstration of elation with laughter that was associated with a variety of different patterns of complex motor behaviour that included performing specific celebratory movements and acting out a Michael Jackson dance move. Electrographically, the seizures were all stereotyped and arose from the right frontal region, followed by a distinct left temporal ictal rhythm that corresponded with the onset of the behaviours. The lesion in the right aPFC was identified as a mixed lesion with both dysembryoplastic neuroepithelial tumour cells and type II cortical dysplasia. The electrographic analysis and unique seizure semiology suggest a connection between the aPFC and the contralateral temporal lobe. This neural pathway appears to be involved in the activation of previously formed procedural memories, creating an intensely positive emotional experience.

Genetic and Environmental Contributions to the Development of Positive Affect in Infancy

2016-01-01

We studied developmental changes in infant positive affect from 6 to 12 months of age, a time marked by increasing use of positive vocalizations, laughter, and social smiles. We estimated the magnitude of genetic and environmental influences on observed and parent reported infant positive affect across development. Participants were drawn from a longitudinal twin study of infancy and toddlerhood (N=536 twin pairs). Mothers and fathers reported on infant temperament and infants were videotaped during two observational tasks assessing positive affect. Parents also reported on their own affect and emotional expression within the family. Biometric models examined genetic and environmental influences that contribute to the developmental continuity of positive affect. Infant positive affect was associated with increased parent positive affect and family expressions of positive affect although not with family expressions of negative affect. In addition, the shared environment accounted for a large portion of variation in infant positive affect and continuity over time. These findings highlight the importance of the family environment in relation to infant positive emotional development. PMID:27797564

Explaining cooperation between non-relatives is a puzzle for both evolutionary biology and the social sciences. In humans, cooperation is often studied in a laboratory setting using economic games such as the prisoners' dilemma. However, such experiments are sometimes criticized for being played for low stakes and by misrepresentative student samples. Golden balls is a televised game show that uses the prisoners' dilemma, with a diverse range of participants, often playing for very large stakes. We use this non-experimental dataset to investigate the factors that influence cooperation when “playing” for considerably larger stakes than found in economic experiments. The game show has earlier stages that allow for an analysis of lying and voting decisions. We found that contestants were sensitive to the stakes involved, cooperating less when the stakes were larger in both absolute and relative terms. We also found that older contestants were more likely to cooperate, that liars received less cooperative behavior, but only if they told a certain type of lie, and that physical contact was associated with reduced cooperation, whereas laughter and promises were reliable signals or cues of cooperation, but were not necessarily detected.

Although there are many clinical programs designed to bring humor into pediatric hospitals, there has been very little research with children or adolescents concerning the specific utility of humor for children undergoing stressful or painful procedures. Rx Laughter™, a non-profit organization interested in the use of humor for healing, collaborated with UCLA to collect preliminary data on a sample of 18 children aged 7–16 years. Participants watched humorous video-tapes before, during and after a standardized pain task that involved placing a hand in cold water. Pain appraisal (ratings of pain severity) and pain tolerance (submersion time) were recorded and examined in relation to humor indicators (number of laughs/smiles during each video and child ratings of how funny the video was). Whereas humor indicators were not significantly associated with pain appraisal or tolerance, the group demonstrated significantly greater pain tolerance while viewing funny videos than when viewing the videos immediately before or after the cold-water task. The results suggest that humorous distraction is useful to help children and adolescents tolerate painful procedures. Further study is indicated to explore the specific mechanism of this benefit.

Ontogenetic Trajectories of Chimpanzee Social Play: Similarities with Humans

2011-01-01

Social play, a widespread phenomenon in mammals, is a multifunctional behavior, which can have many different roles according to species, sex, age, relationship quality between playmates, group membership, context, and habitat. Play joins and cuts across a variety of disciplines leading directly to inquiries relating to individual developmental changes and species adaptation, thus the importance of comparative studies appears evident. Here, we aim at proposing a possible ontogenetic pathway of chimpanzee play (Pan troglodytes) and contrast our data with those of human play. Chimpanzee play shows a number of changes from infancy to juvenility. Particularly, solitary and social play follows different developmental trajectories. While solitary play peaks in infancy, social play does not show any quantitative variation between infancy and juvenility but shows a strong qualitative variation in complexity, asymmetry, and playmate choice. Like laughter in humans, the playful expressions in chimpanzees (at the different age phases) seem to have a role in advertising cooperative dispositions and intentions thus increasing the likelihood of engaging in solid social relationships. In conclusion, in chimpanzees, as in humans, both play behavior and the signals that accompany play serve multiple functions according to the different age phases. PMID:22110630

Spasmodic Dysphonia: a Laryngeal Control Disorder Specific to Speech

PubMed Central

Ludlow, Christy L.

2016-01-01

Spasmodic dysphonia (SD) is a rare neurological disorder that emerges in middle age, is usually sporadic, and affects intrinsic laryngeal muscle control only during speech. Spasmodic bursts in particular laryngeal muscles disrupt voluntary control during vowel sounds in adductor SD and interfere with voice onset after voiceless consonants in abductor SD. Little is known about its origins; it is classified as a focal dystonia secondary to an unknown neurobiological mechanism that produces a chronic abnormality of laryngeal motor neuron regulation during speech. It develops primarily in females and does not interfere with breathing, crying, laughter, and shouting. Recent postmortem studies have implicated the accumulation of clusters in the parenchyma and perivascular regions with inflammatory changes in the brainstem in one to two cases. A few cases with single mutations in THAP1, a gene involved in transcription regulation, suggest that a weak genetic predisposition may contribute to mechanisms causing a nonprogressive abnormality in laryngeal motor neuron control for speech but not for vocal emotional expression. Research is needed to address the basic cellular and proteomic mechanisms that produce this disorder to provide intervention that could target the pathogenesis of the disorder rather than only providing temporary symptom relief.

Automatic facial mimicry in response to dynamic emotional stimuli in five-month-old infants.

2016-12-14

Human adults automatically mimic others' emotional expressions, which is believed to contribute to sharing emotions with others. Although this behaviour appears fundamental to social reciprocity, little is known about its developmental process. Therefore, we examined whether infants show automatic facial mimicry in response to others' emotional expressions. Facial electromyographic activity over the corrugator supercilii (brow) and zygomaticus major (cheek) of four- to five-month-old infants was measured while they viewed dynamic clips presenting audiovisual, visual and auditory emotions. The audiovisual bimodal emotion stimuli were a display of a laughing/crying facial expression with an emotionally congruent vocalization, whereas the visual/auditory unimodal emotion stimuli displayed those emotional faces/vocalizations paired with a neutral vocalization/face, respectively. Increased activation of the corrugator supercilii muscle in response to audiovisual cries and the zygomaticus major in response to audiovisual laughter were observed between 500 and 1000 ms after stimulus onset, which clearly suggests rapid facial mimicry. By contrast, both visual and auditory unimodal emotion stimuli did not activate the infants' corresponding muscles. These results revealed that automatic facial mimicry is present as early as five months of age, when multimodal emotional information is present. © 2016 The Author(s).

Narcolepsy is characterized by excessive daytime somnolence associated with sleep paralysis, hallucinations when falling asleep or awakening, and cataplexy. Early recognition of pediatric narcolepsy is essential for growth and development. We experienced a case of narcolepsy in a three-year-old girl. The patient underwent brain MRI and 24h video-electroencephalogram (EEG) monitoring. Polysomnography (PSG) with multiple sleep latency test (MSLT) and human leukocyte antigen (HLA) DQ typing was performed. The brain MRI was normal. 24h video-EEG monitoring revealed no abnormal slow or epileptiform discharge on interictal EEG, and no EEG change during tongue thrusting, dropping head with laughter, or flopping down, which was consistent with cataplexy associated with narcolepsy. A mean sleep latency of 2.5 min and four episodes of sleep-onset REM periods in five naps were observed in PSG with MSLT. She was positive in HLA-DQB1*0602. Based on these findings, she was diagnosed as narcoleptic with cataplexy. The history, combined with PSG and MSLT, was helpful in the diagnosis of narcolepsy. We report a case of early-onset narcolepsy presenting with excessive sleepiness and cataplexy. Copyright © 2015 The Japanese Society of Child Neurology. Published by Elsevier B.V.

The Complexity of Jokes Is Limited by Cognitive Constraints on Mentalizing

PubMed Central

Launay, Jacques; Curry, Oliver

2016-01-01

Although laughter is probably of deep evolutionary origin, the telling of jokes, being language-based, is likely to be of more recent origin within the human lineage. In language-based communication, speaker and listener are engaged in a process of mutually understanding each other’s intentions (mindstates), with a conversation minimally requiring three orders of intentionality. Mentalizing is cognitively more demanding than non-mentalizing cognition, and there is a well-attested limit at five orders in the levels of intentionality at which normal adult humans can work. Verbal jokes commonly involve commentary on the mindstates of third parties, and each such mindstate adds an additional level of intentionality and its corresponding cognitive load. We determined the number of mentalizing levels in a sample of jokes told by well-known professional comedians and show that most jokes involve either three or five orders of intentionality on the part of the comedian, depending on whether or not the joke involves other individuals’ mindstates. Within this limit there is a positive correlation between increasing levels of intentionality and subjective ratings of how funny the jokes are. The quality of jokes appears to peak when they include five to six levels of intentionality, which suggest that audiences appreciate higher mentalizing complexity whilst working within their natural cognitive constraints.

2017-01-01

Abstract The study aimed to explore the humor processing elicited through the manipulation of artistic drawings. Using the Comprehension–Elaboration Theory of humor as the main research background, the experiment manipulated the head portraits of celebrities based on the independent variables of facial deformation (large/small) and addition of affective features (positive/negative). A 64-channel electroencephalography was recorded in 30 participants while viewing the incongruous drawings of celebrities. The electroencephalography temporal and spectral responses were measured during the three stages of humor which included incongruity detection, incongruity comprehension and elaboration of humor. Analysis of event-related potentials indicated that for humorous vs non-humorous drawings, facial deformation and the addition of affective features significantly affected the degree of humor elicited, specifically: large > small deformation; negative > positive affective features. The N170, N270, N400, N600-800 and N900-1200 components showed significant differences, particularly in the right prefrontal and frontal regions. Analysis of event-related spectral perturbation showed significant differences in the theta band evoked in the anterior cingulate cortex, parietal region and posterior cingulate cortex; and in the alpha and beta bands in the motor areas. These regions are involved in emotional processing, memory retrieval, and laughter and feelings of amusement induced by elaboration of the situation. PMID:28402573

This was a prospective longitudinal multisite study of the effects of prenatal cocaine and/or opiate exposure on temperament in 4-month-olds of the Maternal Lifestyle Study (N = 958: 366 cocaine exposed, 37 opiate exposed, 33 exposed to both drugs, 522 matched comparison). The study evaluated positivity and negativity during The Behavior Assessment of Infant Temperament (Garcia Coll et al., 1988). Parents rated temperament (Infant Behavior Questionnaire; Rothbart, 1981). Cocaine-exposed infants showed less positivity overall, mainly during activity and threshold items, more negativity during sociability items, and less negativity during irritability and threshold items. Latent profile analysis indicated individual temperament patterns were best described by three groups: low/moderate overall reactivity, high social negative reactivity, and high nonsocial negative reactivity. Infants with heavy cocaine exposure were more likely in high social negative reactivity profile, were less negative during threshold items, and required longer soothing intervention. Cocaine- and opiate-exposed infants scored lower on Infant Behavior Questionnaire smiling and laughter and duration of orienting scales. Opiate-exposed infants were rated as less respondent to soothing. By including a multitask measure of temperament we were able to show context-specific behavioral dysregulation in prenatally cocaine-exposed infants. The findings indicate flatter temperament may be specific to nonsocial contexts, whereas social interactions may be more distressing for cocaine-exposed infants.

We designed algorithms which (1) determine the electrode contacts that induce STPSs and (2) provide a programming protocol to eliminate STPS and maintain the optimal motor functions. Our objective is to test the effectiveness of these algorithms. Materials and Methods 454 PD patients who underwent programming sessions after STN-DBS implantations were retrospectively analyzed. Only STPS patients were enrolled. In these patients, the contacts inducing STPS were found and the programming protocol algorithms used. Results Eleven patients were diagnosed with STPS. Of these patients, two had four episodes of crying, and two had four episodes of mirthful laughter. In one patient, two episodes of abnormal sense of spatial orientation were observed. Hallucination episodes were observed twice in one patient, while five patients recorded eight episodes of hypomania. There were no statistical differences between the UPDRS-III under the final stimulation parameter (without STPS) and previous optimum UPDRS-III under the STPSs (p = 1.000). Conclusion The flow diagram used for determining electrode contacts that induce STPS and the programming protocol employed in the treatment of these symptoms are effective. PMID:28894620

We hypothesized that gelotophobia (the fear of being laughed at), gelotophilia (the joy of being laughed at), and katagelasticism (the joy of laughing at others) relate differently to character strengths. In Study 1 (N = 5,134), self-assessed gelotophobia was primarily negatively related to strengths (especially to lower hope, zest, and love), whereas only modesty yielded positive relations. Gelotophilia demonstrated mainly positive relations with humor, zest, and social intelligence. Katagelasticism existed widely unrelated from character strengths with humor demonstrating the comparatively highest coefficients. Study 2 consisted of N = 249 participants who provided self- and peer-ratings of strengths and self-reports on the three dispositions. The results converged well with those from Study 1. When comparing self- and peer-reports, those higher in gelotophobia under-estimated and those higher in gelotophilia over-estimated their virtuousness, whereas those higher in katagelasticism seemed to have a realistic appraisal of their strengths. Peer-rated (low) hope and modesty contributed to the prediction of gelotophobia beyond self-reports. The same was true for low modesty, creativity, low bravery, and authenticity for gelotophilia and for low love of learning regarding katagelasticism. Results suggest that there is a stable relation between the way people deal with ridicule and laughing and their virtuousness.

The prevalence of pathological laughing and crying in multiple sclerosis (MS) is 10%. It has been speculated that the anatomical lesion responsible for the pathological laughing is located in the pontine base, prefrontal cortex, and cerebellum. We report an 18-year-old male patient presenting with pathological laughing and hypomania. In his neurological examination, he had a euphoric effect with ataxic walking and dysarthria speech. He had a bilateral conjugated gaze limitation, with a prominent bilateral horizontal nystagmus on left gaze, dysmetria, dysdiadokokinesia, and remarkable dysfunction in a heel-to-shin test on the left. The IgG index in cerebrospinal fluid was normal with an oligoclonal band was present. In cranial MRI, there was a lesion on central pons which was hypointense in T1 images with contrast enhancement and hyperintense in T2 and flair images. Also another lesion in right brachium pontis which did not contrast enhancement but was hyperintense on T2 and flair images was present. There was an elevation of myoinositol/creatine ratio and choline and a reduction of NAA in proton MR spectroscopy. MR spectroscopic evaluation of the patient demonstrated the demyelination process. There has been no report of patients in whom pathological laughter was the presenting symptom of clinically isolated brainstem syndrome.

The ways in which humour can be used are related to the manifold interpersonal functions humour can serve, some of which are positive, and some negative. In the present study, phasic changes in the functional coupling of prefrontal and posterior cortex (EEG coherence) during other people’s auditory displays of happy and sad mood were recorded to predict people’s typical use of humour in social interactions. Greater use of benevolent humour, the intentions of which are in keeping with the characteristics of “laughing-with” humour, was associated with greater decreases of prefrontal-posterior coupling during the processing of happy laughter. More loose prefrontal-posterior coupling indicates loosening of control of the prefrontal cortex over the incoming perceptual information, thereby opening up the perceptual gate and allowing the brain to become more affected by the social-emotional signals. Greater use of humour styles linked to malicious intentions of “laughing-at” humour was associated with responses indicating a wider opened perceptual gate during the processing of other people’s crying. The findings are consistent with the idea that typical humour styles develop in line with the rewarding values of their outcomes (e.g., interaction partners are happy or hurt), which in turn are defined through the individuals’ latent interpersonal goals.

Patients' and Caregivers' Attributes in a Meaningful Care Encounter: Similarities and Notable Differences

2012-01-01

In today's healthcare system, there is an imbalance between what patients expect of caregivers' care and their perception of the care they get. How is it possible to reduce this imbalance? The aim of this paper was to describe attributes associated with meaningful encounters in the Swedish healthcare system based on patients' and caregivers' written narratives and to note the differences and similarities between the attributes identified by the two groups. This paper is a qualitative descriptive study. The analysis was guided by qualitative content analyses. Based on patients' narratives, attributes associated with a meaningful encounter fell into four categories: the kind-hearted caregiver, the thoughtful caregiver, the mutually oriented caregiver, and the helpful caregiver. Based on caregivers' narratives, the attributes were categorized as being humane, caring through physical contact, caring by nurturing communication, joy and laughter in care, and a sense of mutuality. The results show that there are both similarities and differences in patients' and caregivers' opinions about the attributes of a meaningful encounter. Knowing more about the attributes associated with meaningful encounters makes it possible for caregivers to individualize care for patients and makes it easier to help and support patients in what they most need support with.

New surgical concepts: nasal tip function.

Since the birth of plastic surgery, rhinoplasty has been an outstanding chapter. Facial balance has been endeavoured with two parameters: size and shape. Now, however, the criterion for harmony has involved two more parameters; position and function. Position is related to other facial elements, such as, upper maxilla, upper lip, forehead, and frontonasal sulcus. Function is important because nasal superficial musculoaponeurotic system (SMAS) muscles are important for Nasal tip movement. To understand this better, we must analyze the nasal SMAS, which consists of primary or intrinsic and secondary or extrinsic muscles. When the extrinsics contract, they allow function of the intrinsics. They are the ala nasalis dilator, the ala nasalis elevator, the tranversus, and the tip depressor. Obvious hypertrophies of the dilator and the elevator has been observed in young athletes. Our method combines conventional, new, and modern aspects. It is conventional because the alar cartilages have been completely freed by intercartilaginous and marginal approaches, and the upper or lower border trimmed according to the case. It is more important to measure how much cartilage is left, than how much is removed. The new aspect is consideration of nasal SMAS to treat short noses that display a tendency to descend with laughter, and the modern aspect is the evaluation of dynamic surgical results, apart from the static.

Phenotype of a child with Angelman syndrome born to a woman with Prader-Willi syndrome.

This report describes the phenotype, from early childhood to adolescence, of a girl with Angelman syndrome (AS) born following a maternal transmission of a germline paternal 15q11.2-q13 deletion. During early childhood, she showed a typical AS phenotype, such as jerky movements, poor sleep, high voltage electroencephalography pattern, epilepsy, and a severe developmental disability. As she grew older, indications of phenotypical traits similar to Prader-Willi syndrome (PWS) appeared, in particular hyperphagic behavior and a body fat distribution similar to that reported in PWS. She generally showed cheerful AS behavior and had the characteristic outbursts of laughter, but her attitude to other people did not reflect the usual shared enjoyment of interaction seen in children with AS. In unfamiliar surroundings, she withdrew socially, similar to children with PWS, and her insistence on the same, rigid routines was similar to behavior patterns in PWS. The dysmorphic facial features that characterize AS were blurred in adolescence. The specified features that this AS patient had in common with PWS were hardly incidental and, if verified by upcoming case reports of children born to women with a paternal 15q11.2-q13 deletion, they may show new aspects of genetic imprinting. © 2015 Wiley Periodicals, Inc.

To evaluate the psychometric properties of the Norwegian version of the Patient Competency Rating Scale (PCRS) in patients with traumatic brain injury (TBI) at 12 months post-injury. Demographic and injury-related data were registered upon admission to the hospital in 148 TBI patients with mild, moderate, or severe TBI. At 12 months post-injury, competency in activities and global functioning were measured using the PCRS patient version and the Glasgow Outcome Scale-Extended (GOSE). Descriptive reliability statistics, factor analysis and Rasch modeling were applied to explore the psychometric properties of the PCRS. External validity was evaluated using the GOSE. The PCRS can be divided into three subscales that reflect interpersonal/emotional, cognitive, and activities of daily living competency. The three-factor solution explained 56.6% of the variance in functioning. The internal consistency was very good, with a Cronbach's α of 0.95. Item 30, "controlling my laughter", did not load above 0.40 on any factors and did not fit the Rasch model. The external validity of the subscales was acceptable, with correlations between 0.50 and 0.52 with the GOSE. The Norwegian version of the PCRS is reliable, has an acceptable construct and external validity, and can be recommended for use during the later phases of TBI.

Thyrotoxic periodic paralysis (TPP) is an uncommon complication of Graves' disease, characterized by the triad of acute hypokalemia without total body potassium deficit, episodic muscle paralysis, and thyrotoxicosis. Graves' encephalopathy is an extremely rare form of encephalopathy associated with autoimmune thyroid disease (EAATD), characterized by neuropsychiatric symptoms, increased antithyroid antibodies and cerebrospinal fluid protein concentration, nonspecific electroencephalogram abnormalities, and cortico-responsiveness. Coexistence of both these complications in the same patient has not been reported before. We herein present a 48-year-old white male patient with TPP and encephalopathy as initial presentations of Graves' disease. Flaccid tetraparesis was reversed a few hours after potassium level correction and the patient did not suffer any relapse with the successful pharmaceutical management of the thyroid function. One month later, the patient presented with dizziness and behavioral symptoms, such as inappropriate laughter and anger. Brain magnetic resonance imaging revealed meningeal enhancement and cerebrospinal fluid analysis showed a mild protein increase, with a blood-brain barrier disruption. With the suspicion of EAATD, the patient was treated with high doses of corticosteroids and improved dramatically. To our knowledge this is the first reported coexistence of potentially treatable TPP and EAATD as initial neurological manifestations of Graves' disease, thereby underscoring the necessity of suspicion of possible underlying Graves' disease in patients with acute paralysis and encephalopathy of unclear origin.

Music and social bonding: “self-other” merging and neurohormonal mechanisms

Tarr, Bronwyn; Launay, Jacques; Dunbar, Robin I. M.

2014-01-01

It has been suggested that a key function of music during its development and spread amongst human populations was its capacity to create and strengthen social bonds amongst interacting group members. However, the mechanisms by which this occurs have not been fully discussed. In this paper we review evidence supporting two thus far independently investigated mechanisms for this social bonding effect: self-other merging as a consequence of inter-personal synchrony, and the release of endorphins during exertive rhythmic activities including musical interaction. In general, self-other merging has been experimentally investigated using dyads, which provide limited insight into large-scale musical activities. Given that music can provide an external rhythmic framework that facilitates synchrony, explanations of social bonding during group musical activities should include reference to endorphins, which are released during synchronized exertive movements. Endorphins (and the endogenous opioid system (EOS) in general) are involved in social bonding across primate species, and are associated with a number of human social behaviors (e.g., laughter, synchronized sports), as well as musical activities (e.g., singing and dancing). Furthermore, passively listening to music engages the EOS, so here we suggest that both self-other merging and the EOS are important in the social bonding effects of music. In order to investigate possible interactions between these two mechanisms, future experiments should recreate ecologically valid examples of musical activities. PMID:25324805

Science Is A Laughing Matter

NASA Astrophysics Data System (ADS)

Weissman, P. R.

2017-12-01

Humor can be a powerful tool in communicating science to a professional or lay audience. Humor relaxes the audience and encourages them to pay better attention, lest they miss the next funny comment or slide (and be sure that you provide it for them). Humor sends the message that the speaker is so confident in his/her material that the speaker can joke about it; this tends to deter spurious or trivial questions after the talk. But humor is not for the faint of heart. It requires planning, practice, and especially, good timing. Good humorists are always on the lookout for new material that they can use in a talk, be it a funny image, a cartoon, or a quip from a movie or from a professional comedian. But the humorist must also be a strict self-censor. Politically incorrect material can be extremely dangerous and can backfire on the speaker. Don't ever use material that insults some faction in the audience, even if that faction is not present at the moment or too stupid to notice. Don't include so much humor that the science in your talk gets lost in the laughter. Lastly, speakers who are not funny, should never attempt humor. There is nothing so damaging to a talk as poor humor that falls flat on its face. But if you have a good sense of humor, go for it. Life should be fun and so should science.

Supernumerary psu dic(15;15) chromosomes make up approximately 40% of livebirths possessing marker chromosomes. Markers with various chromosomal contents as well as a spectrum of phenotypes have been described. A few individuals with Angelman syndrome (AS) who have paternal uniparental disomy (UPD) for chromosome 15 or a 15q12 deletion in addition to a supernumerary psu dic(15;15) have been reported. We studied a patient who had a clinical phenotype consistent with AS including ataxic gait, severe mental retardation, absent speech and inappropriate laughter. Cytogenetic and FISH analysis showed a 47,XX,+psu dic(15q12;15q12) karyotype in which the supernumerary chromosome was positive for DNA probesmore » in the AS critical region. Additional molecular analyses confirmed the presence of four copies of the 15q11{r_arrow}13 segment and that the psu dic(15;15) was maternal in origin. Two distal chromosome 15 markers showed normal, biparental inheritance for the two normal 15 homologues. A patient similar to ours was outlined by Stupca et al., although results of DNA analyses and parental origin were not given. In both patients, tetrasomy 15q12 resulted in an AS phenotype. The significance of the ratio of maternally:paternally derived sequences, 3:1 in our case, is unknown at present.« less

Prevalence of Pseudobulbar Affect following Stroke: A Systematic Review and Meta-Analysis.

Several studies have reported that emotional lability is a common consequence of stroke. However, there is uncertainty about the "true" prevalence of the condition because, across these studies, patients have been recruited at different stages of recovery, from different settings, and using different diagnostic methods. There have been no systematic reviews of the published evidence to ascertain how the prevalence of poststroke pseudobulbar affect (PBA) might vary according to these factors. A systematic review and meta-analysis of the published literature were undertaken. A total of 15 studies (n = 3391 participants) met inclusion criteria for the review. Meta-analysis estimated that the prevalence of PBA was 17% (95% confidence interval 12%-24%) acutely (<1 month post stroke), 20% (14%-29%) post acutely (1-6 months post stroke), and 12% (8%-17%) in the medium to longer term (>6 months post stroke). The evidence from the published literature, although limited, is that crying is a more common PBA presentation following stroke than laughter. PBA is a common condition that affects approximately 1 in 5 stroke survivors at the acute and postacute phases, and 1 in 8 survivors beyond 6 months post stroke. These prevalence data are very important for clinicians and the commissioners of services. Copyright © 2016 National Stroke Association. Published by Elsevier Inc. All rights reserved.

Auditory to Visual Cross-Modal Adaptation for Emotion: Psychophysical and Neural Correlates.

Adaptation is fundamental in sensory processing and has been studied extensively within the same sensory modality. However, little is known about adaptation across sensory modalities, especially in the context of high-level processing, such as the perception of emotion. Previous studies have shown that prolonged exposure to a face exhibiting one emotion, such as happiness, leads to contrastive biases in the perception of subsequently presented faces toward the opposite emotion, such as sadness. Such work has shown the importance of adaptation in calibrating face perception based on prior visual exposure. In the present study, we showed for the first time that emotion-laden sounds, like laughter, adapt the visual perception of emotional faces, that is, subjects more frequently perceived faces as sad after listening to a happy sound. Furthermore, via electroencephalography recordings and event-related potential analysis, we showed that there was a neural correlate underlying the perceptual bias: There was an attenuated response occurring at ∼ 400 ms to happy test faces and a quickened response to sad test faces, after exposure to a happy sound. Our results provide the first direct evidence for a behavioral cross-modal adaptation effect on the perception of facial emotion, and its neural correlate. © The Author 2016.

Seizure-like activity in a juvenile Angelman syndrome mouse model is attenuated by reducing Arc expression

Angelman syndrome (AS) is a neurodevelopmental disorder arising from loss-of-function mutations in the maternally inherited copy of the UBE3A gene, and is characterized by an absence of speech, excessive laughter, cognitive delay, motor deficits, and seizures. Despite the fact that the symptoms of AS occur in early childhood, behavioral characterization of AS mouse models has focused primarily on adult phenotypes. In this report we describe juvenile behaviors in AS mice that are strain-independent and clinically relevant. We find that young AS mice, compared with their wild-type littermates, produce an increased number of ultrasonic vocalizations. In addition, young AS mice have defects in motor coordination, as well as abnormal brain activity that results in an enhanced seizure-like response to an audiogenic challenge. The enhanced seizure-like activity, but not the increased ultrasonic vocalizations or motor deficits, is rescued in juvenile AS mice by genetically reducing the expression level of the activity-regulated cytoskeleton-associated protein, Arc. These findings suggest that therapeutic interventions that reduce the level of Arc expression have the potential to reverse the seizures associated with AS. In addition, the identification of aberrant behaviors in young AS mice may provide clues regarding the neural circuit defects that occur in AS and ultimately allow new approaches for treating this disorder.

Emotional voices in context: A neurobiological model of multimodal affective information processing

2011-12-01

Just as eyes are often considered a gateway to the soul, the human voice offers a window through which we gain access to our fellow human beings' minds - their attitudes, intentions and feelings. Whether in talking or singing, crying or laughing, sighing or screaming, the sheer sound of a voice communicates a wealth of information that, in turn, may serve the observant listener as valuable guidepost in social interaction. But how do human beings extract information from the tone of a voice? In an attempt to answer this question, the present article reviews empirical evidence detailing the cerebral processes that underlie our ability to decode emotional information from vocal signals. The review will focus primarily on two prominent classes of vocal emotion cues: laughter and speech prosody (i.e. the tone of voice while speaking). Following a brief introduction, behavioral as well as neuroimaging data will be summarized that allows to outline cerebral mechanisms associated with the decoding of emotional voice cues, as well as the influence of various context variables (e.g. co-occurring facial and verbal emotional signals, attention focus, person-specific parameters such as gender and personality) on the respective processes. Building on the presented evidence, a cerebral network model will be introduced that proposes a differential contribution of various cortical and subcortical brain structures to the processing of emotional voice signals both in isolation and in context of accompanying (facial and verbal) emotional cues.

Patterns of Negotiation

NASA Astrophysics Data System (ADS)

Sood, Suresh; Pattinson, Hugh

Traditionally, face-to-face negotiations in the real world have not been looked at as a complex systems interaction of actors resulting in a dynamic and potentially emergent system. If indeed negotiations are an outcome of a dynamic interaction of simpler behavior just as with a complex system, we should be able to see the patterns contributing to the complexities of a negotiation under study. This paper and the supporting research sets out to show B2B (business-to-business) negotiations as complex systems of interacting actors exhibiting dynamic and emergent behavior. This paper discusses the exploratory research based on negotiation simulations in which a large number of business students participate as buyers and sellers. The student interactions are captured on video and a purpose built research method attempts to look for patterns of interactions between actors using visualization techniques traditionally reserved to observe the algorithmic complexity of complex systems. Students are videoed negotiating with partners. Each video is tagged according to a recognized classification and coding scheme for negotiations. The classification relates to the phases through which any particular negotiation might pass, such as laughter, aggression, compromise, and so forth — through some 30 possible categories. Were negotiations more or less successful if they progressed through the categories in different ways? Furthermore, does the data depict emergent pathway segments considered to be more or less successful? This focus on emergence within the data provides further strong support for face-to-face (F2F) negotiations to be construed as complex systems.

The aim of the study is to investigate if the presence of medical clowns during painful procedures in the emergency department (ED) affects children's anxiety and pain. Forty children (4-11 years) admitted to the ED with the need of painful procedures were prospectively enrolled. They were randomly assigned to the clown group, where children interacted with clowns or to the control group in which they were entertained by parents and ED nurses. The children's anxiety was assessed by the Children's Anxiety and Pain Scales; pain was evaluated with the Numerical Rating Scale and Wong-Backer Scale, according to the children's age. Staff and clown's opinions were evaluated by means of dedicated questionnaires. Children's anxiety levels in the clown group were significantly lower than those compared with the control group, while children's pain levels did not change between the two groups. The presence of clowns in the ED before and during painful procedures was effective in reducing children's anxiety. • Anxiety and fear caused by medical procedures exacerbate children's pain and may interfere with the procedure. • To reduce anxiety, fear, and pain and to facilitate patient's evaluation, different non-pharmacological approaches have been proposed and positive effects of laughter and humor have been reported. What is New: • The presence of clowns in the waiting room and in the ED during medical evaluation and painful procedures helps to reduce children's anxiety.

“The Bitter Laughter”. When Parody Is a Moral and Affective Priming in Political Persuasion

PubMed Central

D’Errico, Francesca; Poggi, Isabella

2016-01-01

Research on socially aware systems requires fine-grained knowledge of the mechanisms of persuasion in order to promote civic knowledge and aware political participation. Within humor studies, political parody is generally considered a simple pleasant weapon for political evaluation, currently explained by referring to the so called “just a joke effect” (Nabi et al., 2007). Indeed the funny side of parody can induce positive emotions, but it also includes a discrediting act that sometimes produces a “bitter laughter.” The present study aims to understand the role played by negative and moral emotions aroused by parody. A parody is defined as a communicative behavior (a discourse, text, body movement, song) that imitates a communicative behavior or trait displayed by some Target by reproducing it in a distorted way, with the aim of making fun of the Target. Based on a socio-cognitive approach, a distinction is made between “surface” and “deep” parody (Poggi and D’Errico, 2013), with the former simply imitating behaviors actually displayed by the Target, and the latter implying a (humorous) re-categorization of the Target. The paper studies the effect of these two different types of parody on persuasion processes. Results show that the deep parody, as opposed to surface parody, triggers more negative emotions, and in particular indignation, that in turn lead to more negative evaluations of the Target. Moreover, the moral priming of parody is influenced by the Target politician’s gender. PMID:27555825

A meta-analytic investigation of the relation between interpersonal attraction and enacted behavior.

We present a meta-analysis that investigated the relation between self-reported interpersonal attraction and enacted behavior. Our synthesis focused on (a) identifying the behaviors related to attraction; (b) evaluating the efficacy of models of the relation between attraction and behavior; (c) testing the impact of several moderators, including evaluative threat salience, cognitive appraisal salience, and the sex composition of the social interaction; and (d) investigating the degree of agreement between the meta-analytic findings and an ethnographic analysis. Using a multilevel modeling approach, an analysis of 309 effect sizes (N = 5,422) revealed a significant association (z = .20) between self-reported attraction and enacted behavior. Key findings include: (a) that the specific behaviors associated with attraction (e.g., eye contact, smiling, laughter, mimicry) are those behaviors research has linked to the development of trust/rapport; (b) direct behaviors (e.g., physical proximity, talking to), compared with indirect behaviors (e.g., eye contact, smiling, mimicry), were more strongly related to self-reported attraction; and (c) evaluative threat salience (e.g., fear of rejection) reduced the magnitude of the relation between direct behavior and affective attraction. Moreover, an ethnographic analysis revealed consistency between the behaviors identified by the meta-analysis and those behaviors identified by ethnographers as predictive of attraction. We discuss the implications of our findings for models of the relation between attraction and behavior, for the behavioral expressions of emotions, and for how attraction is measured and conceptualized.

A visit to the village of Saye.

PubMed

1992-01-01

This brief article describes the changes in the village of Saye, Burkina Faso which were recognizable after 20 years absence. Rainfall was plentiful and it was the best season for agriculture in 20 years; the sorghum swayed in the breezes ready for harvest. There are 28 women and village elders who still recognized their visitor, Ramata. The changes in family planning attitudes and sexuality were evident in the way men and women freely joke and laugh about sexual issues in a good humored but not superficial way. The respected El Hadj (meaning that he had visited Mecca) Sawadogo, president of the local Naam group, was the one who cracked jokes which brought laughter to the audience. The taboos are still there, but everyone agrees that family planning is a good idea because it reduces suffering and the people do not still have enough food to eat. Birth spacing is generally accepted, but there is resistance to stopping births. There is growing tolerance toward premarital pregnancies, and polygamy among younger women, which leads to fractious polygamous wives. 20 years ago it was a radical act to show a film on sex education, where pen and ink outlines gave shape to a naked teenaged boy and girl next to each other on the screen. The audience response was a roar of disbelief and the author feared that the local prefet would put him in jail for disturbing public order and violating a taboo.

Narcolepsy is characterized by chronic excessive daytime sleepiness with episodic sleep attacks. There are several associated symptoms of narcolepsy: cataplexy (bilateral muscle weakness without loss of consciousness provoked by an emotional trigger, e.g. laughter), sleep paralysis and hypnagogic-hypnopompic hallucinations. Most cases are sporadic; familial narcolepsy contributes to only 1-5% of all cases. While most cases of narcolepsy are idiopathic and are not associated with clinical or radiographic evidence of brain pathology, symptomatic or secondary narcolepsy may occur occasionally in association with lesions caused by tumours, demyelination or strokes of the diencephalon, midbrain, and pons. There are some examples of non-specific brainstem lesions found in magnetic resonance imaging (MRI) in patients with idiopathic narcolepsy. The authors present eleven patients from a five-generation family with many members who suffer from episodic excessive daytime sleepiness. Narcolepsy was diagnosed in 9 patients. Sleepiness was frequently associated with cataplexy, hypnagogic-hypnopompic hallucinations and sleep paralysis. Improvement in their clinical state was observed during the treatment with modafinil. All probands had MRI of the brain, routine blood tests, EEG, polysomnography, examination of the level of hypocretin in cerebrospinal fluid and evaluation by means of Epworth and Stanford Sleepiness Scales. In 9 patients with narcolepsy, decreased thickness of the substantia nigra was found and in six of them degenerative lesions in the pontine substantia nigra were also noticed. The significance of these changes remains unclear. No data have been published until now concerning the presence of any brain lesions in patients with familial narcolepsy.

In the ear of the beholder: how age shapes emotion processing in nonverbal vocalizations.

It is well established that emotion recognition of facial expressions declines with age, but evidence for age-related differences in vocal emotions is more limited. This is especially true for nonverbal vocalizations such as laughter, sobs, or sighs. In this study, 43 younger adults (M = 22 years) and 43 older ones (M = 61.4 years) provided multiple emotion ratings of nonverbal emotional vocalizations. Contrasting with previous research, which often includes only one positive emotion (happiness) versus several negative ones, we examined 4 positive and 4 negative emotions: achievement/triumph, amusement, pleasure, relief, anger, disgust, fear, and sadness. We controlled for hearing loss and assessed general cognitive decline, cognitive control, verbal intelligence, working memory, current affect, emotion regulation, and personality. Older adults were less sensitive than younger ones to the intended vocal emotions, as indicated by decrements in ratings on the intended emotion scales and accuracy. These effects were similar for positive and negative emotions, and they were independent of age-related differences in cognitive, affective, and personality measures. Regression analyses revealed that younger and older participants' responses could be predicted from the acoustic properties of the temporal, intensity, fundamental frequency, and spectral profile of the vocalizations. The two groups were similarly efficient in using the acoustic cues, but there were differences in the patterns of emotion-specific predictors. This study suggests that ageing produces specific changes on the processing of nonverbal vocalizations. That decrements were not attenuated for positive emotions indicates that they cannot be explained by a positivity effect in older adults. PsycINFO Database Record (c) 2014 APA, all rights reserved.

Angelman syndrome: A review highlighting musculoskeletal and anatomical aberrations.

Sachdeva, Rohit; Donkers, Sarah J; Kim, Soo Y

Angelman's syndrome (AS) is a genetic neurodevelopment disorder. The cause is a known abnormality involving the maternal inherited ubiquitin-protein ligase (UBE3A) gene. Clinical characteristics universal to the disorder are well documented in the literature and include developmental delay, seizures, ataxia, altered tone, severely impaired speech and intellect, as well as an overall happy demeanor, frequent bouts of laughter, and hypermotoric behavior. Associated with this disorder are several musculoskeletal aberrations. To date, a review of case studies reporting on these musculoskeletal changes has not been carried out. Thus, the purpose of this paper was to provide an overview of the musculoskeletal changes present in individuals with AS. In our review of 21 case reports from 1965-2013, the most consistently reported anatomical changes were of the craniofacial region. These include microcephaly, brachycephaly, a palpable occipital groove, prognathism, and wide spaced teeth. Other musculoskeletal abnormalities less frequently reported in the literature include scoliosis, excessive lumbar lordosis, and pes planus. Given that the majority of the case reports reviewed was of young children, the possibility of underreporting musculoskeletal changes which may manifest in the later years of life may be present. Early diagnosis and interventions to minimize secondary complications are crucial to maintain quality of life. An overall multidisciplinary approach is emphasized to maximize developmental potential for these individuals. Future prospective studies that follow patients into adulthood are needed to better understand the prevalence and development of secondary musculoskeletal changes, which in turn can inform intervention techniques and preventative measures.

2009-01-01

The purpose of this pilot study was to test a dance intervention and explore the role of peer support to improve the diabetes outcomes of A1C, weight, body fat, and blood pressure in African American women with type 2 diabetes. This study was conducted in a community-based outpatient clinic. A mixed methods design was used. A total of 46 women, 26 to 83 years of age, were randomized to either the 12-week dance group or usual care group. Both between group and intraindividual group differences were analyzed from baseline to 12 weeks. Focus group interviews explored the role of peer support through semistructured discussions for the women enrolled in the dance group. Results showed significant group mean differences in systolic blood pressure (BP) and body fat. Paired t tests showed significant reductions in all the diabetes outcomes for the dance group and significant increases in glycolated hemoglobin (A1C) and systolic BP for the usual care group. The emergent themes of the focus groups were that a diabetes diagnosis was devastating, and changing eating habits and taking medications was often difficult. Peer support in the dance group was expressed as camaraderie, enjoyment, and laughter, which fostered attendance. Dancing 2 times per week for 12 weeks produced significant group differences in systolic BP and body fat and significant intraindividual changes. The implications are that dancing in a supportive environment with peers may be an effective strategy for diabetes educators to help those with diabetes to become more physically active and improve diabetes outcomes and overall health.

The aim of this study is to evaluate and quantify dynamic soft-tissue strain in the human face using real-time 3-dimensional imaging technology. Thirteen subjects (8 women, 5 men) between the ages of 18 and 70 were imaged using a dual-camera system and 3-dimensional optical analysis (ARAMIS, Trilion Quality Systems, Pa.). Each subject was imaged at rest and with the following facial expressions: (1) smile, (2) laughter, (3) surprise, (4) anger, (5) grimace, and (6) pursed lips. The facial strains defining stretch and compression were computed for each subject and compared. The areas of greatest strain were localized to the midface and lower face for all expressions. Subjects over the age of 40 had a statistically significant increase in stretch in the perioral region while lip pursing compared with subjects under the age of 40 (58.4% vs 33.8%, P = 0.015). When specific components of lip pursing were analyzed, there was a significantly greater degree of stretch in the nasolabial fold region in subjects over 40 compared with those under 40 (61.6% vs 32.9%, P = 0.007). Furthermore, we observed a greater degree of asymmetry of strain in the nasolabial fold region in the older age group (18.4% vs 5.4%, P = 0.03). This pilot study illustrates that the face can be objectively and quantitatively evaluated using dynamic major strain analysis. The technology of 3-dimensional optical imaging can be used to advance our understanding of facial soft-tissue dynamics and the effects of animation on facial strain over time.

This study provides updated information regarding the prevalence and characteristics of weight stigma in popular adolescent television programming, using a sample of favorite shows named by diverse adolescents. Participants in a large, population-based study of Minnesota adolescents (N = 2,793, mean age = 14.4) listed their top three favorite television shows. A coding instrument was developed to analyze randomly selected episodes from the most popular 10 programs. Weight-stigmatizing incidents were compared across television show characteristics and characters' gender and weight status. Half (50%) of the 30 episodes analyzed contained at least one weight-stigmatizing incident. Both youth- and adult-targeted shows contained weight-stigmatizing comments, but the percent of these comments was much higher for youth-targeted (55.6%) than general audience-targeted shows (8.3%). Male characters were more likely than females to engage in (72.7% vs. 27.3%), and be the targets of, weight stigma (63.6% vs. 36.4%), and there was no difference in the amount of weight stigmatizing directed at average weight females compared to overweight females. Targets of these instances showed a negative response in only about one-third of cases, but audience laughter followed 40.9% of cases. The portrayal of weight stigmatization on popular television shows-including targeting women of average weight-sends signals to adolescents about the wide acceptability of this behavior and the expected response, which may be harmful. Prevention of weight stigmatization should take a multi-faceted approach and include the media. Future research should explore the impact that weight-related stigma in television content has on viewers. © 2014 Wiley Periodicals, Inc.

Transforming a conservative company--one laugh at a time.

PubMed

Hudson, K M

2001-01-01

You wouldn't think of Brady Corporation as an obvious place in which to find a fun culture. This traditional Midwestern company, a manufacturer of industrial signs and other identification products, didn't even allow employees to have coffee at their desks until 1989. But when Katherine Hudson became CEO in 1994, she and her executive team determined that injecting some fun into the company's serious culture could create positive effects within the organization and contribute to increased performance and sales. In this article, Hudson distills her approach to overhauling Brady's culture into six principles of serious fun: More people than you might think are comfortable having fun at work; used with an awareness of cultural sensitivities, fun and laughter really are well-understood international languages; humor can help companies get through tough times; fun can be embodied in formal programs; spontaneous efforts at humor can also be effective; and encouraging fun should begin at the top. She richly illustrates each principle with examples. At Brady, getting people to loosen up and enjoy themselves has fostered a company esprit de corps and greater team camaraderie. It has started conversations that have sparked innovation, helped to memorably convey corporate messages to employees, and increased productivity by reducing stress, among other benefits. And the company has doubled its sales and almost tripled its net income and market capitalization over the past seven years. Brady's experience suggests that promoting fun within the workplace can lead not only to a robust corporate culture but also to improved business performance.

Infants laugh by 4 months, but whether they understand humour based on social or cognitive factors is unclear. We conducted two longitudinal studies of 4-, 6-, and 8-month-olds (N = 60), and 5-, 6-, and 7-month-olds (N = 53) to pinpoint the onset of independent humour perception and determine when social and cognitive factors are most salient. Infants were shown six events in randomized repeated-measures designs: two ordinary events and two absurd iterations of those events, with parents' affect manipulated (laugh or neutral) during the latter. Four-month-olds did not smile/laugh more at absurd events, but exhibited a significant heart rate deceleration. Five-month-olds independently appraised absurd events as humorous, smiling/laughing despite their parents' neutrality. Parent laughter did not influence infants of any age to smile more, but captured 4-month-olds' attention. Results suggest that 4-month-olds laugh in response to social cues, while 5-month-olds' can laugh in response to cognitive features. Statement of contribution What is already known on this subject? By 6 months, infants can independently appraise absurd events as humorous, but it is not known whether younger infants can. What does this study add? This study replicated the finding on younger infants, showing that 5-month-olds are similarly capable of independent humour appraisal. These studies also found that although 4-month-olds do not respond to absurd events with positive affect, they do exhibit a heart rate decrease that is unrelated to looking. These studies help delineate when social and cognitive factors contribute to infant humour perception. © 2017 The British Psychological Society.

Current concepts in the pharmacotherapy of pseudobulbar affect.

PubMed

Pioro, Erik P

2011-06-18

Arising in settings of CNS insult, pseudobulbar affect (PBA) consists of uncontrollable episodes of crying or laughter incongruent to the patient's mood. The syndrome has been described by a plethora of names, including pathological laughing and crying, emotional lability, emotionalism and emotional incontinence, which hampers efforts to survey published assessments of pharmacological intervention. Still, until quite recently, all treatment has unavoidably been off-label, chiefly involving antidepressants. Using PBA and other syndrome names as search terms, a PubMed search for English-language case reports and therapeutic trials involving at least five patients identified 22 such publications from 1980 through to 2010. Among the seven randomized, double-blind, antidepressant studies with placebo control, two trials assessed 106 and 123 subjects, respectively. However, the other five assessed only 12-28 subjects, and only one of these seven trials (with 28 subjects) measured change in syndrome severity using a validated scale. The three randomized, double-blind studies of dextromethorphan plus quinidine assessed 129, 150 and 326 subjects. Among these studies, two were placebo-controlled and all three used a validated severity scale. Across all placebo-controlled trials, response to active treatment - either an antidepressant or dextromethorphan/quinidine - has in general been significantly greater than response to placebo, but placebo response has sometimes been substantial, suggesting caution in interpreting uncontrolled findings. In October 2010, dextromethorphan/quinidine received approval from the US FDA as first-in-class PBA pharmacotherapy. Advocates of a continuing role for antidepressants, notably selective serotonin reuptake inhibitors, can point to numerous positive case reports and trials, the potential benefit of attempting to treat PBA and concomitant depression without using multiple drugs, and the ever-present need to tailor treatment to the individual patient.

Pseudobulbar Affect Correlates With Mood Symptoms in Parkinsonian Disorders but Not Amyotrophic Lateral Sclerosis.

Pseudobulbar affect (PBA) is a syndrome of affective disturbance associated with inappropriate laughter and crying, independent of mood. PBA is common in amyotrophic lateral sclerosis (ALS) and increasingly recognized in Parkinson's disease (PD) and atypical parkinsonism (aP). Correlates of PBA have not been systematically studied. The purpose of this study was to determine whether cognitive and psychiatric comorbidities correlated with patient-reported symptoms of PBA by using the Center for Neurological Study-Lability Scale among patients with ALS, PD, and aP. A total of 108 patients (PD, N=53; aP, N=29; ALS, N=26) completed a cognitive screener and self-reported measures of lability, depression, anxiety, apathy, and quality of life. Statistical analyses included one- and two-way analyses of covariance to evaluate group differences, Pearson's correlations to determine relationships between PBA symptoms and comorbidities, multiple regression for predicting PBA symptom severity in clinical correlates, and chi-square t tests for predicting demographic variables. PBA symptom severity did not vary between the three groups. Younger age and worse anxiety correlated with PBA symptom severity in all three groups, whereas depression and poor mental health/quality of life only correlated with PBA symptom severity in the PD and aP groups. PD and aP patients may be more likely to benefit from treatment with antidepressants. Increased PBA symptoms were associated with declines in cognitive functioning in the aP group, but sufficient numbers of PD and ALS patients with cognitive dysfunction may not have been recruited. The results suggest the possibility of an alternate pathophysiologic mechanism for PBA, which may vary between neurological disorders and disease progression. Mood and cognition are of particular relevance and should be evaluated when symptoms of PBA are suspected.

Behavioural symptoms are common in moderate to severe Alzheimer's disease (AD) and are improved by memantine with the most pronounced effect on agitation/aggression. Dextromethorphan in combination with quinidine is the only drug approved by US Food and Drug Administration for the treatment of pseudobulbar affect (PBA) on the basis of efficacy in patients with multiple sclerosis or amyotrophic lateral sclerosis. The aim of our study was to evaluate the efficacy of memantine on PBA in patients with AD. In a prospective, double-blind, case-control study to assess PBA with pathological laughter and crying scale patients were administered memantine (final dose of 20 mg daily) or citalopram (20 mg once daily), each for 10 weeks. The number of episodes of involuntary emotional expression, Neuropsychiatric Inventory (NPI) and Overt Aggression Scale-Modified (OAS-M) total scores were also recorded. Furthermore, the platelet serotonin (5-HT) concentration was measured. Although memantine had beneficial effects on PBA, it also had a crucial impact on behavioural symptoms, especially aggression and agitation (to an average of 3.5 times higher end-point scores on OAS-M and increase of NPI total scores for an average of 114% of initial value). Therefore, the study was prematurely stopped. In addition, we had evidenced a drop of platelet 5-HT concentration (to an average of 73% of initial value). Surprisingly, our research showed the opposite action of memantine on neuropsychiatric symptoms as expected. In a limited number of AD patients with PBA, memantine had a beneficial effect on involuntary emotional expression, but it potentiated agitation/aggression, irritability and caused a crucial drop of the platelet 5-HT concentration.

The construction of power in family medicine bedside teaching: a video observation study.

Bedside teaching is essential for helping students develop skills, reasoning and professionalism, and involves the learning triad of student, patient and clinical teacher. Although current rhetoric espouses the sharing of power, the medical workplace is imbued with power asymmetries. Power is context-specific and although previous research has explored some elements of the enactment and resistance of power within bedside teaching, this exploration has been conducted within hospital rather than general practice settings. Furthermore, previous research has employed audio-recorded rather than video-recorded observation and has therefore focused on language and para-language at the expense of non-verbal communication and human-material interaction. A qualitative design was adopted employing video- and audio-recorded observations of seven bedside teaching encounters (BTEs), followed by short individual interviews with students, patients and clinical teachers. Thematic and discourse analyses of BTEs were conducted. Power is constructed by students, patients and clinical teachers throughout different BTE activities through the use of linguistic, para-linguistic and non-verbal communication. In terms of language, participants construct power through the use of questions, orders, advice, pronouns and medical/health belief talk. With reference to para-language, participants construct power through the use of interruption and laughter. In terms of non-verbal communication, participants construct power through physical positioning and the possession or control of medical materials such as the stethoscope. Using this paper as a trigger for discussion, we encourage students and clinical teachers to reflect critically on how their verbal and non-verbal communication constructs power in bedside teaching. Students and clinical teachers need to develop their awareness of what power is, how it can be constructed and shared, and what it means for the student-patient-doctor relationship within bedside teaching. © Blackwell Publishing Ltd 2013.

Cough in children is a common reason for medical consultations and affects quality of life. There are little population-based data on the epidemiology of recurrent cough in children and how this varies by age and sex, or between children with and without wheeze. We determined the prevalence of cough throughout childhood, comparing several standardised cough questions. We did this for the entire population and separately for girls and boys, and for children with and without wheeze. In a population-based prospective cohort from Leicestershire, UK, we assessed prevalence of cough with repeated questionnaires from early childhood to adolescence. We asked whether the child usually coughed more than other children, with or without colds, had night-time cough or cough triggered by various factors (triggers, related to increased breathing effort, allergic or food triggers). We calculated prevalence from age 1 to 18 years using generalised estimating equations for all children, and for children with and without wheeze. Of 7670 children, 10% (95% CI 10-11%) coughed more than other children, 69% (69-70%) coughed usually with a cold, 34% to 55% age-dependently coughed without colds, and 25% (25-26%) had night-time cough. Prevalence of coughing more than peers, with colds, at night, and triggered by laughter varied little throughout childhood, while cough without colds and cough triggered by exercise, house dust or pollen became more frequent with age. Cough was more common in boys than in girls in the first decade of life, differences got smaller in early teens and reversed after the age of 14 years. All symptoms were more frequent in children with wheeze. Prevalence of cough in children varies with age, sex and with the questions used to assess it, suggesting that comparisons between studies are only valid for similar questions and age groups.

Harsh humour: a therapeutic discourse.

McCreaddie, May

2010-11-01

Humour research in healthcare has tended to focus on rehearsed as opposed to spontaneous humour. This paper reports an empirical example of spontaneous humour in healthcare interactions: a negative case analysis from a constructivist grounded theory study. Twenty Clinical Nurse Specialist (CNS)-patient interactions and CNS pre- and postinteraction audio diaries provided the baseline data corpus. Follow-up interviews, field notes, focus groups and observations serviced theory generation with a constant comparison approach to data collection and analyses. Interpretative and illustrative frameworks incorporating humour theories, non-laughter humour support, discursive features and prosodical features of speech were applied to all data. This paper is based upon the negative case comprising a 90-minute follow-up interview and 10 hours of field note observations. The negative case - a CNS working with female drug users' sexual and reproductive health needs - contradicted emerging findings from the baseline data corpus. First, the negative case had greater awareness of humour, deliberately initiated humour and recognised parameters and exclusion zones. Second, a good patient personal was evident in the baseline data corpus but the negative case worked with 'bad' patients. Accordingly, a specific type of humour - harsh humour - was evident in the negative case. Harsh humour used areas of potential discord (e.g. drug use) as a focus of humour creation and maintenance. The deliberate initiation of harsh humour enabled the negative case and her colleagues to achieve their aims by engaging effectively with unpredictable, reluctant and recalcitrant patients. The negative case demonstrates how humour can be used to therapeutically enhance healthcare interactions with disenfranchised individuals. Humour is not superficial but integral to the accomplishment of key aspects of interactions. Health and social care workers should consider the potential for therapeutic humour to engage and maintain all patients - disenfranchised or otherwise - in healthcare interactions. © 2010 Blackwell Publishing Ltd.

To investigate the physiological and psychological effects of windows and daylight on registered nurses. To date, evidence has indicated that appropriate environmental lighting with characteristics similar to natural light can improve mood, alertness, and performance. The restorative effects of windows also have been documented. Hospital workspaces generally lack windows and daylight, and the impact of the lack of windows and daylight on healthcare employees' well being has not been thoroughly investigated. Data were collected using multiple methods with a quasi-experimental approach (i.e., biological measurements, behavioral mapping, and analysis of archival data) in an acute-care nursing unit with two wards that have similar environmental and organizational conditions, and similar patient populations and acuity, but different availability of windows in the nursing stations. Findings indicated that blood pressure (p < 0.0001) decreased and body temperature increased (p = 0.03). Blood oxygen saturation increased (p = 0.02), but the difference was clinically insignificant. Communication (p < 0.0001) and laughter (p = 0.03) both increased, and the subsidiary behavior indicators of sleepiness and deteriorated mood (p = 0.02) decreased. Heart rate (p = 0.07), caffeine intake (p = 0.3), self-reported sleepiness (p = 0.09), and the frequency of medication errors (p = 0.14) also decreased, but insignificantly. The findings support evidence from laboratory and field settings of the benefits of windows and daylight. A possible micro-restorative effect of windows and daylight may result in lowered blood pressure and increased oxygen saturation and a positive effect on circadian rhythms (as suggested by body temperature) and morning sleepiness.

Intellectual disability inherited in an autosomal-recessive fashion represents an important fraction of severe cognitive-dysfunction disorders. Yet, the extreme heterogeneity of these conditions markedly hampers gene identification. Here, we report on eight affected individuals who were from three consanguineous families and presented with severe intellectual disability, absent speech, shy character, stereotypic laughter, muscular hypotonia that progressed to spastic paraplegia, microcephaly, foot deformity, decreased muscle mass of the lower limbs, inability to walk, and growth retardation. Using a combination of autozygosity mapping and either Sanger sequencing of candidate genes or next-generation exome sequencing, we identified one mutation in each of three genes encoding adaptor protein complex 4 (AP4) subunits: a nonsense mutation in AP4S1 (NM_007077.3: c.124C>T, p.Arg42∗), a frameshift mutation in AP4B1 (NM_006594.2: c.487_488insTAT, p.Glu163_Ser739delinsVal), and a splice mutation in AP4E1 (NM_007347.3: c.542+1_542+4delGTAA, r.421_542del, p.Glu181Glyfs∗20). Adaptor protein complexes (AP1-4) are ubiquitously expressed, evolutionarily conserved heterotetrameric complexes that mediate different types of vesicle formation and the selection of cargo molecules for inclusion into these vesicles. Interestingly, two mutations affecting AP4M1 and AP4E1 have recently been found to cause cerebral palsy associated with severe intellectual disability. Combined with previous observations, these results support the hypothesis that AP4-complex-mediated trafficking plays a crucial role in brain development and functioning and demonstrate the existence of a clinically recognizable syndrome due to deficiency of the AP4 complex.

Angelman syndrome (AS) is characterized by severe psychomotor retardation, speech impairment, happy disposition with bursts of laughter, ataxia, convulsions, and some distinct physical anomalies. Correct diagnosis of AS is important because of its clinical implications, and once the disease is confirmed, familial genetic counseling becomes crucial. We evaluated 22 patients with a putative diagnosis of AS by both clinical and molecular cytogenetic analysis. A deletion of the region 15q11-13 could be identified cytogenetically in 11 cases by high-resolution technique (group I). Four additional cases were confirmed by fluorescence in situ hybridization (FISH) study with D15S11, SNRPN, D15S10, and GABRB 3 [Prader-Willi syndrome (PWS)/AS region probes] (group II). The common deletion of GABRB 3 was documented in those AS cases (n = 15) by FISH. The other 7 cases exhibited no deletion over 15q11-13 at either the cytogenetic or molecular level (group III). We compared the following associated neurological disorders: convulsions and abnormal EEG, microcephaly, sleep and behavior problems, brain anomalies proved by image studies, sexual precocity with pineal tumor among the three groups, as well as other clinical conditions including congenital heart disease, obesity, scoliosis, and hypopigmentation. In the present study, the differences in neurological and facial characteristics were not distinct among these groups. However, the associated conditions were more frequently observed in the patients with deletion than in those without deletion. The EEG features of AS appear to be less sufficient in helping identify patients at an early age before the clinical features become obvious. Therefore, a region involved in the major As phenotypes may contain only one or more tightly contiguous genes around the GABRB 3 locus, which may explain the clinical heterogeneity in AS.

Cataplexy is the sudden muscle weakness brought on by strong emotions, particularly joking, laughter, or anger. Cataplexy may involve only certain group of muscles or the entire voluntary musculature. In rare cases, symptoms of cataplexy can be seen during the course of some inherited diseases (Niemann-Pick type C (NPC), Prader-Willi syndrome, myotonic dystrophy, Norrie disease). We report the successful use of miglustat, a reversible inhibitor of the enzyme glucosylceramide synthase, approved for use in Gaucher's disease, and which catalyses the first step in the biosynthesis of most glycosphingolipid, in a boy with NPC with cataplexy. A 9-year-old boy was admitted for assessments of frequent "drop attacks" while laughing. The filipin fluorescence tests of cultured skin fibroblasts revealed massive accumulation of unesterified cholesterol, confirming the diagnosis of NPC disease. Molecular studies confirmed the diagnosis of NPC too. After approval from the bioethics committee, miglustat was initiated on the child at 100mg three times a day. Cataplectic attacks disappeared completely after 6 months on treatment, and patient continues to be in remission from the cataplectic attacks at 16 months follow-up. There was no further progression of neurological signs or symptoms or splenomegaly, with some improvement in cognitive function as well as social, affective and attention problems, up-gaze, and gait. Miglustat was well tolerated with no side effects observed. In summary, this is the first report of miglustat treatment of cataplexy in NPC. Long-term follow-up for continuing efficacy and tolerability in a larger cohort with NPC is needed to substantiate our observation. © 2010 European Paediatric Neurology Society.

With aging, the detrimental effects of stress can impair a person's ability to learn and sustain memory. Humor and its associated mirthful laughter can reduce stress by decreasing the hormone cortisol. Chronic release of cortisol can damage hippocampal neurons, leading to impairment of learning and memory. Objectives • The study intended to examine the effect of watching a humor video on short-term memory in older adults. Design • The research team designed a randomized, controlled trial. The study took place at Loma Linda University in Loma Linda, CA, USA. The study included 30 participants: 20 normal, healthy, older adults-11 males and 9 females-and 10 older adults with type 2 diabetes mellitus (T2DM)-6 males and 4 females. The study included 2 intervention groups of older adults who viewed humorous videos, a healthy group (humor group), aged 69.9 ± 3.7 y, and the diabetic group, aged 67.1 ± 3.8 y. Each participant selected 1 of 2 humorous videos that were 20 min in length, either a Red Skeleton comedy or a montage of America's Funniest Home Videos. The control group, aged 68.7 ± 5.5 y, did not watch a humor video and sat in quiescence. A standardized, neuropsychological, memory-assessment tool, the Rey Auditory Verbal Learning Test (RAVLT), was used to assess the following abilities: (1) learning, (2) recall, and (3) visual recognition. The testing occurred twice, once before (RAVLT1) and once after (RAVLT2) the humorous video for the humor and diabetic groups, and once before (RAVLT1) and once after (RAVLT2) the period of quiescence for the control group. At 5 time points, measurements of salivary cortisol were also obtained. The Kruskal-Wallis test was used to measure significance of the data based on the 3 groups. In the humor, diabetic, and control groups, (1) learning ability improved by 38.5%, 33.4%, and 24.0%, respectively (P = .025); (2) delayed recall improved by 43.6%, 48.1%, and 20.3%, respectively (P = .064); and (3) visual recognition increased by 12.6%, 16.7%, and 8.3%, respectively (P = .321). For levels of salivary cortisol, the research team found significant and borderline decreases for the humor group between baseline and (1) post-RAVLT1 (P = .047), (2) postvideo (P = .046), and (3) post-RAVLT2 (P = .062). The diabetic group showed significant decreases between baseline and (1) post-RAVLT1 (P = .047), (2) postvideo (P = .025), and (3) post-RAVLT2 (P = .034). The study found no significant changes for the control group. The research findings supported potential clinical and rehabilitative benefits for humor that can be applied to whole-person wellness programs for older adults. The cognitive components-learning ability and delayed recall-become more challenging as individuals age and are essential to older adults for providing a high quality of life: mind, body, and spirit. Because older adults can experience age-related memory deficits, complementary, enjoyable, and beneficial humor therapies should be implemented for them.

A Vicious Cycle: A Cross-Sectional Study of Canine Tail-Chasing and Human Responses to It, Using a Free Video-Sharing Website

PubMed Central

Burn, Charlotte C.

2011-01-01

Tail-chasing is widely celebrated as normal canine behaviour in cultural references. However, all previous scientific studies of tail-chasing or ‘spinning’ have comprised small clinical populations of dogs with neurological, compulsive or other pathological conditions; most were ultimately euthanased. Thus, there is great disparity between scientific and public information on tail-chasing. I gathered data on the first large (n = 400), non-clinical tail-chasing population, made possible through a vast, free, online video repository, YouTube™. The demographics of this online population are described and discussed. Approximately one third of tail-chasing dogs showed clinical signs, including habitual (daily or ‘all the time’) or perseverative (difficult to distract) performance of the behaviour. These signs were observed across diverse breeds. Clinical signs appeared virtually unrecognised by the video owners and commenting viewers; laughter was recorded in 55% of videos, encouragement in 43%, and the commonest viewer descriptors were that the behaviour was ‘funny’ (46%) or ‘cute’ (42%). Habitual tail-chasers had 6.5+/−2.3 times the odds of being described as ‘Stupid’ than other dogs, and perseverative dogs were 6.8+/−2.1 times more frequently described as ‘Funny’ than distractible ones were. Compared with breed- and age-matched control videos, tail-chasing videos were significantly more often indoors and with a computer/television screen switched on. These findings highlight that tail-chasing is sometimes pathological, but can remain untreated, or even be encouraged, because of an assumption that it is ‘normal’ dog behaviour. The enormous viewing figures that YouTube™ attracts (mean+/−s.e. = 863+/−197 viewings per tail-chasing video) suggest that this perception will be further reinforced, without effective intervention.

The aims of this study are: (1) to describe language and temperament characteristics of one group of low risk preterm (PR) children and a group of full-term (FT) children and (2) to identify those factors which can predict language outcomes at 30 months of age, with special attention on temperament. There is evidence of differences between very or extremely PR and FT children in relation to characteristics of temperament and language development. However, not many studies have been carried out with healthy PR children. The participants were 142 low risk PR children (mean gestational age (GA): 32.60 weeks) and 49 FT children (mean GA 39.84 weeks). The temperament of the children was assessed at 10 months of age through the Infant Behavior Questionnaire-Revised (IBQ-R). At 22 months of age the cognitive development of the children was assessed through the Spanish adaptation of the Batelle Developmental Inventory (BDI). In order to assess the children's language development the Galician adaptation of the MacArthur-Bates CDI was applied at 30 months of age. In addition, socio-demographic information about the children and their families was gathered at birth. The results indicate that there were no significant differences in the language measures of interest (word production, MLU3, and sentence complexity) between groups. The only differences found between the PR and the FT children in the IBQ-R were restricted to the smiling and laughter and the fear subscales. Hierarchical regression analyses performed indicate that GA did not have any predictive effect on language measures taken at 30 months. Cognitive scores were an important predictor of language measures, although certain temperament subscales contributed in a significant way to the variance of language measures, particularly low intensity pleasure, approach, high intensity pleasure, sadness, and vocal reactivity. Therefore, extroverted (positive affectivity) temperament seems to be beneficial for language development. Copyright © 2015 Elsevier Inc. All rights reserved.

Further contributions to the understanding of stage fright: narcissistic issues.

PubMed

Gabbard, G O

1983-01-01

Stage fright is an overdetermined symptom of all persons who must perform before an audience. The performer may experience disintegration anxiety as he searches for a mirroring or an idealized object to make him feel complete and loved. Anxiety may be generated by his fantasy that he is stirring up the envy and persecution of others as a defense against his own envy. He also may develop anxiety over his fear that his success is depriving others and harming them. The performer's concern over his greed may activate unconscious anxieties about depleting the very object he seeks of all it has to give. Conversely, if he projects the greediness onto the audience, he may fear that he will be devoured. Finally, he may become extraordinarily anxious over the thrust toward autonomy that his assertive act of performing represents to him. He may feel that if he does not perform according to the expectations of his audience-mother, he will lose the audience's love and admiration. Although it is a potentially disabling problem, stage fright adds a unique dimension to the vitality of live performance. It is emblematic of the electric interaction between the performer and the audience that makes the theater a place of magic. Audience members bring a certain degree of reality to the performer's fears: they may cheer him on, but they may also secretly hope for disaster. If a faux pas occurs, they may ridicule him with laughter, and a poorly executed performance may result in fidgeting, at least, and hurling of vegetables, at worst. As the performer balances on the razor's edge of the audience's ambivalent empathy for him, a sense of dangerous excitement is created. This interactional tension makes live performance a unique medium that can never be replaced by film or recording. As one performer put it, "It creates a feeling of delicious dread, a mixture of horror and anticipation."

Central pontine myelinolysis (CPM) usually occurs with rapid correction of severe chronic hyponatremia. Despite the pronounced fluctuations in serum osmolality, CPM is rarely seen in diabetics. This is a case report of CPM associated with hyperglycemia. A 45-year-old non-smoking and non-alcoholic African American male with past medical history of type 2 diabetes, hypertension, stage V chronic kidney disease and hypothyroidism presented with a two-week history of intermittent episodes of gait imbalance, slurred speech and inappropriate laughter. Physical examination including complete neurological assessment and fundoscopic examination were unremarkable. Laboratory evaluation was significant for serum sodium: 140 mmol/L, potassium: 3.9 mmol/L, serum glucose: 178 mg/dL and serum osmolality: 317 mosmol/kg. His ambulatory blood sugars fluctuated between 100 and 600 mg/dL in the six weeks prior to presentation, without any significant or rapid changes in his corrected serum sodium or other electrolyte levels. MRI brain demonstrated a symmetric lesion in the central pons with increased signal intensity on T2- and diffusion-weighted images. After neurological consultation and MRI confirmation, the patient was diagnosed with CPM secondary to hyperosmolar hyperglycemia. Eight-week follow-up with neurology was notable for near-complete resolution of symptoms. This case report highlights the importance of adequate blood glucose control in diabetics. Physicians should be aware of complications like CPM, which can present atypically in diabetics and is only diagnosed in the presence of a high index of clinical suspicion.

IMPORTANCE The literature on cingulate gyrus epilepsy in the magnetic resonance imaging era is limited to case reports and small case series. To our knowledge, this is the largest study of surgically confirmed epilepsy arising from the anterior or posterior cingulate region. OBJECTIVE To characterize the clinical and electrophysiological findings of epilepsies arising from the anterior and posterior cingulate gyrus. DESIGN, SETTING, AND PARTICIPANTS We studied consecutive cingulate gyrus epilepsy cases identified retrospectively from the Cleveland Clinic and University of Texas Southwestern Medical Center epilepsy databases from 1992 to 2009. Participants included 14 consecutive cases of cingulate gyrus epilepsies confirmed by restricted magnetic resonance image lesions and seizure freedom or marked improvement following lesionectomy. MAIN OUTCOMES AND MEASURES The main outcome measure was improvement in seizure frequency following surgery. The clinical, video electroencephalography, neuroimaging, pathology, and surgical outcome data were reviewed. RESULTS All 14 patients had cingulate epilepsy confirmed by restricted magnetic resonance image lesions and seizure freedom or marked improvement following lesionectomy. They were divided into 3 groups based on anatomical location of the lesion and corresponding seizure semiology. In the posterior cingulate group, all 4 patients had electroclinical findings suggestive of temporal origin of the epilepsy. The anterior cingulate cases were divided into a typical (Bancaud) group (6 cases with hypermotor seizures and infrequent generalization with the presence of fear, laughter, or severe interictal personality changes) and an atypical group (4 cases presenting with simple motor seizures and a tendency for more frequent generalization and less-favorable long-term surgical outcome). All atypical cases were associated with an underlying infiltrative astrocytoma. CONCLUSIONS AND RELEVANCE Posterior cingulate gyrus epilepsy may present with electroclinical findings that are suggestive of temporal lobe epilepsy and can be considered as another example of pseudotemporal epilepsies. The electroclinical presentation and surgical outcome of lesional anterior cingulate epilepsy is possibly influenced by the underlying pathology. This study highlights the difficulty in localizing seizures arising from the cingulate gyrus in the absence of a magnetic resonance image lesion. PMID:23753910

"Did You Climax or Are You Just Laughing at Me?" Rare Phenomena Associated With Orgasm.

2017-07-01

The study of the human orgasm has shown a core set of physiologic and psychological symptoms experienced by most individuals. The study of normal sheds light on the abnormal and has spotlighted rare physical and psychological symptoms experienced by some individuals in association with orgasm. These phenomena are rare and, as is typical of rare phenomena, their documentation in the medical literature is largely confined to case studies. To identify peri-orgasmic phenomena, defined as unusual physical or psychological symptoms subjectively experienced by some individuals as part of the orgasm response, distinct from the usual or normal orgasm response. A list of peri-orgasmic phenomena was made with help from sexual health colleagues and, using this list as a foundation, a literature search was performed of articles published in English. Publications included in this review report on physical or psychological phenomena at the time of orgasm that are distinct from psychological, whole-body, and genito-pelvic sensations commonly experienced at the time of orgasm. Cases of physical symptoms related to the physiology of sexual intercourse and not specifically to orgasm were excluded. Case studies of peri-orgasmic phenomena were reviewed, including cases describing cataplexy (weakness), crying, dysorgasmia, dysphoria, facial and/or ear pain, foot pain, headache, pruritus, laughter, panic attack, post-orgasm illness syndrome, seizures, and sneezing. The literature review confirms the existence of diverse and frequently replicated peri-orgasmic phenomena. The value of case studies is in the collection and recording of observations so that hypotheses can be formed about the observed phenomena. Accordingly, this review could inspire further research on the neurophysiologic mechanisms of orgasm. Reinert AE, Simon JA. "Did You Climax or Are You Just Laughing at Me?"

Background Cough in children is a common reason for medical consultations and affects quality of life. There are little population-based data on the epidemiology of recurrent cough in children and how this varies by age and sex, or between children with and without wheeze. We determined the prevalence of cough throughout childhood, comparing several standardised cough questions. We did this for the entire population and separately for girls and boys, and for children with and without wheeze. Methods In a population-based prospective cohort from Leicestershire, UK, we assessed prevalence of cough with repeated questionnaires from early childhood to adolescence. We asked whether the child usually coughed more than other children, with or without colds, had night-time cough or cough triggered by various factors (triggers, related to increased breathing effort, allergic or food triggers). We calculated prevalence from age 1 to 18 years using generalised estimating equations for all children, and for children with and without wheeze. Results Of 7670 children, 10% (95% CI 10–11%) coughed more than other children, 69% (69–70%) coughed usually with a cold, 34% to 55% age-dependently coughed without colds, and 25% (25–26%) had night-time cough. Prevalence of coughing more than peers, with colds, at night, and triggered by laughter varied little throughout childhood, while cough without colds and cough triggered by exercise, house dust or pollen became more frequent with age. Cough was more common in boys than in girls in the first decade of life, differences got smaller in early teens and reversed after the age of 14 years. All symptoms were more frequent in children with wheeze. Conclusions Prevalence of cough in children varies with age, sex and with the questions used to assess it, suggesting that comparisons between studies are only valid for similar questions and age groups.

The biology and evolution of music: a comparative perspective.

PubMed

Fitch, W Tecumseh

2006-05-01

Studies of the biology of music (as of language) are highly interdisciplinary and demand the integration of diverse strands of evidence. In this paper, I present a comparative perspective on the biology and evolution of music, stressing the value of comparisons both with human language, and with those animal communication systems traditionally termed "song". A comparison of the "design features" of music with those of language reveals substantial overlap, along with some important differences. Most of these differences appear to stem from semantic, rather than structural, factors, suggesting a shared formal core of music and language. I next review various animal communication systems that appear related to human music, either by analogy (bird and whale "song") or potential homology (great ape bimanual drumming). A crucial comparative distinction is between learned, complex signals (like language, music and birdsong) and unlearned signals (like laughter, ape calls, or bird calls). While human vocalizations clearly build upon an acoustic and emotional foundation shared with other primates and mammals, vocal learning has evolved independently in our species since our divergence with chimpanzees. The convergent evolution of vocal learning in other species offers a powerful window into psychological and neural constraints influencing the evolution of complex signaling systems (including both song and speech), while ape drumming presents a fascinating potential homology with human instrumental music. I next discuss the archeological data relevant to music evolution, concluding on the basis of prehistoric bone flutes that instrumental music is at least 40,000 years old, and perhaps much older. I end with a brief review of adaptive functions proposed for music, concluding that no one selective force (e.g., sexual selection) is adequate to explaining all aspects of human music. I suggest that questions about the past function of music are unlikely to be answered definitively and are thus a poor choice as a research focus for biomusicology. In contrast, a comparative approach to music promises rich dividends for our future understanding of the biology and evolution of music.

Chimpanzees (Pan troglodytes) Produce the Same Types of ‘Laugh Faces’ when They Emit Laughter and when They Are Silent

The ability to flexibly produce facial expressions and vocalizations has a strong impact on the way humans communicate, as it promotes more explicit and versatile forms of communication. Whereas facial expressions and vocalizations are unarguably closely linked in primates, the extent to which these expressions can be produced independently in nonhuman primates is unknown. The present work, thus, examined if chimpanzees produce the same types of facial expressions with and without accompanying vocalizations, as do humans. Forty-six chimpanzees (Pan troglodytes) were video-recorded during spontaneous play with conspecifics at the Chimfunshi Wildlife Orphanage. ChimpFACS was applied, a standardized coding system to measure chimpanzee facial movements, based on FACS developed for humans. Data showed that the chimpanzees produced the same 14 configurations of open-mouth faces when laugh sounds were present and when they were absent. Chimpanzees, thus, produce these facial expressions flexibly without being morphologically constrained by the accompanying vocalizations. Furthermore, the data indicated that the facial expression plus vocalization and the facial expression alone were used differently in social play, i.e., when in physical contact with the playmates and when matching the playmates’ open-mouth faces. These findings provide empirical evidence that chimpanzees produce distinctive facial expressions independently from a vocalization, and that their multimodal use affects communicative meaning, important traits for a more explicit and versatile way of communication. As it is still uncertain how human laugh faces evolved, the ChimpFACS data were also used to empirically examine the evolutionary relation between open-mouth faces with laugh sounds of chimpanzees and laugh faces of humans. The ChimpFACS results revealed that laugh faces of humans must have gradually emerged from laughing open-mouth faces of ancestral apes. This work examines the main evolutionary changes of laugh faces since the last common ancestor of chimpanzees and humans. PMID:26061420

Seizure ending signs in patients with dyscognitive focal seizures.

Signs indicating the end of a focal seizure with loss of awareness and/or responsiveness but without progression to focal or generalized motor symptoms are poorly defined and can be difficult to determine. Not recognizing the transition from ictal to postictal behaviour can affect seizure reporting accuracy by family members and may lead to delayed or a lack of examination during EEG monitoring, erroneous seizure localization and inadequate medical intervention for prolonged seizure duration. Our epilepsy monitoring unit database was searched for focal seizures without secondary generalization for the period from 2007 to 2011. The first focal seizure in a patient with loss of awareness and/or responsiveness and/or behavioural arrest, with or without automatisms, was included. Seizures without objective symptoms or inadequate video-EEG quality were excluded. A total of 67 patients were included, with an average age of 41.7 years. Thirty-six of the patients had seizures from the left hemisphere and 29 from the right. All patients showed an abrupt change in motor activity and resumed contact with the environment as a sign of clinical seizure ending. Specific ending signs (nose wiping, coughing, sighing, throat clearing, or laughter) were seen in 23 of 47 of temporal lobe seizures and 7 of 20 extra-temporal seizures. Seizure ending signs are often subtle and the most common finding is a sudden change in motor activity and resumption of contact with the environment. More distinct signs, such as nose wiping, coughing or throat clearing, are not specific to temporal lobe onset. A higher proportion of seizures during sleep went unexamined, compared to those during wakefulness. This demonstrates that seizure semiology can be very subtle and arousals from sleep during monitoring should alert staff. Patient accounts of seizure frequency appear to be unreliable and witness reports need to be taken into account. [Published with video sequences].

To develop a behavioural observation method to simultaneously assess distractors and communication/teamwork during surgical procedures through direct, on-site observations; to establish the reliability of the method for long (>3 h) procedures. Observational categories for an event-based coding system were developed based on expert interviews, observations and a literature review. Using Cohen's κ and the intraclass correlation coefficient, interobserver agreement was assessed for 29 procedures. Agreement was calculated for the entire surgery, and for the 1st hour. In addition, interobserver agreement was assessed between two tired observers and between a tired and a non-tired observer after 3 h of surgery. The observational system has five codes for distractors (door openings, noise distractors, technical distractors, side conversations and interruptions), eight codes for communication/teamwork (case-relevant communication, teaching, leadership, problem solving, case-irrelevant communication, laughter, tension and communication with external visitors) and five contextual codes (incision, last stitch, personnel changes in the sterile team, location changes around the table and incidents). Based on 5-min intervals, Cohen's κ was good to excellent for distractors (0.74-0.98) and for communication/teamwork (0.70-1). Based on frequency counts, intraclass correlation coefficient was excellent for distractors (0.86-0.99) and good to excellent for communication/teamwork (0.45-0.99). After 3 h of surgery, Cohen's κ was 0.78-0.93 for distractors, and 0.79-1 for communication/teamwork. The observational method developed allows a single observer to simultaneously assess distractors and communication/teamwork. Even for long procedures, high interobserver agreement can be achieved. Data collected with this method allow for investigating separate or combined effects of distractions and communication/teamwork on surgical performance and patient outcomes.

Intellectual disability inherited in an autosomal-recessive fashion represents an important fraction of severe cognitive-dysfunction disorders. Yet, the extreme heterogeneity of these conditions markedly hampers gene identification. Here, we report on eight affected individuals who were from three consanguineous families and presented with severe intellectual disability, absent speech, shy character, stereotypic laughter, muscular hypotonia that progressed to spastic paraplegia, microcephaly, foot deformity, decreased muscle mass of the lower limbs, inability to walk, and growth retardation. Using a combination of autozygosity mapping and either Sanger sequencing of candidate genes or next-generation exome sequencing, we identified one mutation in each of three genes encoding adaptor protein complex 4 (AP4) subunits: a nonsense mutation in AP4S1 (NM_007077.3: c.124C>T, p.Arg42(∗)), a frameshift mutation in AP4B1 (NM_006594.2: c.487_488insTAT, p.Glu163_Ser739delinsVal), and a splice mutation in AP4E1 (NM_007347.3: c.542+1_542+4delGTAA, r.421_542del, p.Glu181Glyfs(∗)20). Adaptor protein complexes (AP1-4) are ubiquitously expressed, evolutionarily conserved heterotetrameric complexes that mediate different types of vesicle formation and the selection of cargo molecules for inclusion into these vesicles. Interestingly, two mutations affecting AP4M1 and AP4E1 have recently been found to cause cerebral palsy associated with severe intellectual disability. Combined with previous observations, these results support the hypothesis that AP4-complex-mediated trafficking plays a crucial role in brain development and functioning and demonstrate the existence of a clinically recognizable syndrome due to deficiency of the AP4 complex.

An investigation into vocal expressions of emotions: the roles of valence, culture, and acoustic factors

NASA Astrophysics Data System (ADS)

Sauter, Disa

This PhD is an investigation of vocal expressions of emotions, mainly focusing on non-verbal sounds such as laughter, cries and sighs. The research examines the roles of categorical and dimensional factors, the contributions of a number of acoustic cues, and the influence of culture. A series of studies established that naive listeners can reliably identify non-verbal vocalisations of positive and negative emotions in forced-choice and rating tasks. Some evidence for underlying dimensions of arousal and valence is found, although each emotion had a discrete expression. The role of acoustic characteristics of the sounds is investigated experimentally and analytically. This work shows that the cues used to identify different emotions vary, although pitch and pitch variation play a central role. The cues used to identify emotions in non-verbal vocalisations differ from the cues used when comprehending speech. An additional set of studies using stimuli consisting of emotional speech demonstrates that these sounds can also be reliably identified, and rely on similar acoustic cues. A series of studies with a pre-literate Namibian tribe shows that non-verbal vocalisations can be recognized across cultures. An fMRI study carried out to investigate the neural processing of non-verbal vocalisations of emotions is presented. The results show activation in pre-motor regions arising from passive listening to non-verbal emotional vocalisations, suggesting neural auditory-motor interactions in the perception of these sounds. In sum, this thesis demonstrates that non-verbal vocalisations of emotions are reliably identifiable tokens of information that belong to discrete categories. These vocalisations are recognisable across vastly different cultures and thus seem to, like facial expressions of emotions, comprise human universals. Listeners rely mainly on pitch and pitch variation to identify emotions in non verbal vocalisations, which differs with the cues used to comprehend speech. When listening to others' emotional vocalisations, a neural system of preparatory motor activation is engaged.

Production Transcript for Ep31_The James Webb Space Telescope.mp3 [00:00:00] >> Houston! We have a podcast. Welcome to the official podcast of the NASA Johnson Space Center, Episode 31, the James Webb Space Telescope. I'm Gary Jordan, and I'll be your host today. So on this podcast, we bring in the experts, NASA scientists, engineers, astronauts, bring them right here on the show to tell you everything about NASA. So today we are talking about the James Webb Space Telescope with Jonathan Homan. He's the Johnson Space Center Project Manager for Webb's Chamber A testing. Chamber A is the giant vacuum chamber that we have here in Texas. So Jonathan and I had a great discussion about what the James Webb Space Telescope is. Some of the testing that was actually done actually wrapped up two weeks ago here in Houston, but also some of the testing in other centers, as well as what the telescope is destined to find. So with no further delay, let's go light speed and jump right ahead to our talk with Mr. Jonathan Homan. Enjoy. [00:00:53] [ Music ] [00:01:01] >> T minus five seconds and counting... [inaudible]. [00:01:08] >> Houston! We have a podcast. [00:01:12] [ Music ] [00:01:17] >> Jonathan, thanks so much for coming today on the podcast. I know you are a very busy man right now, especially because the James Webb is kind of wrapping up its testing operations here at Johnson, is that right? [00:01:29] >> That is correct. No, I'm glad to be here, and yeah, we wrapped up the testing probably right before Thanksgiving. [00:01:38] >> All right. [00:01:38] >> And now we're in kind of what we're calling like the de-integration phase from how we had to test it to packaging it up so it can get ready for its next step of its project, getting ready for launch. [00:01:50] >> And that's happening soon, right? [00:01:51] >> Oh yeah. No, it's-- we're actually putting it in its shipping container tomorrow and-- [00:01:56] >> Yeah! [00:01:57] >> It will be leaving the Johnson Space Center late Monday night, probably Tuesday morning. [00:02:05] >> Okay. [00:02:05] >> And leaving Ellington on Thursday. [00:02:07] >> Sweet! All right! So that's it! [00:02:09] >> That's it! [00:02:10] >> Go out for a drink after that, celebrate, I am done! [00:02:13] >> Correct [laughs]. [00:02:13] >> And then head off to the next guy. Where's it going next actually? [00:02:17] >> So it's flying to Los Angeles, and will be at the Northup Bremen facility in Redondo Beach, south of LAX, where it gets integrated with the sun shield and the spacecraft bus, so the, you know, the sun shield has been, you know, one of the huge parts of the telescope and one of the most important parts, so it has a series of testing once its fully integrated, mostly deployments and some acoustic testing. [00:02:46] >> All right, well fantastic. That's why I think you're the perfect person to have here, since you've been here working with the James Webb Space Telescope for quite some time now, so you kind of have a good sense of not only the testing, but a little bit more about just what is this telescope and what is it going to do? So I kind of want to just kind of dive into that, just the whole overview of what is the James Webb space telescope? So let's start with that. What is it? [00:03:12] >> Okay so you know James Webb is kind of a general purpose science tool. It is part of the next generation of great observatories NASA is working on, so if you think of like the Hubble, Hubble was probably the biggest known great observatory of its generation, so you think like, you know, you had Chandah, Hubble, Spitzer, and I think a few other ones that were, you know, smaller, but Hubble was the big one. [00:03:38] >> Yeah. [00:03:39] >> And that's kind of NASA's plan for, you know, the science mission and some of their observations and James Webb is that big, big observatory, so it is not a replacement for Hubble, but a successor. [00:03:56] >> Okay. So from what I know about the telescopes, and I'm definitely not a scientist or physicist or anything, so this is kind of, like Hubble can read things in the visual spectrum, and then Chandra is more kind of x-ray, and Spitzer is more infrared. [00:04:12] >> Correct. [00:04:12] >> Or did I mix those up? [00:04:13] >> No, you're absolutely correct, very good yeah. [00:04:15] >> So then Webb would be the visual spectrum then? [00:04:18] >> No, no, Webb is infrared. [00:04:20] >> I see, okay, infrared. [00:04:22] >> So Hubble is known for being a little bit of ultraviolet, visible was kind of its main spectrum, but it also has a deep field, so it did some infrared type imaging, so if you think of the deep field image it took, where you look at a black spot, and all of a sudden, all these galaxies showed up over time-- [00:04:39] >> Yes, it was like if this really small spot in the sky zoomed in super far, and got-- [00:04:44] >> Yes, that's kind of where James Webb is picking up. [00:04:46] >> Okay, I see. [00:04:47] >> So it is definitely looking at the deeper, further, older light of the universe, so... [00:04:53] >> Fantastic. So what is the benefit of infrared over visual light? [00:04:57] >> Well your infrared, because of its mission objectives, you know, it really needs to be in the infrared spectrum. You know, those objectives are the first light of the universe, when, you know-- [00:05:08] >> Okay, pretty good objective [laughter]. [00:05:10] >> Yeah, yeah, where you have stars and galaxies first pulling things together, lighting up, you know, looking for the-- how the evolution of galaxies and star systems, the birth of stars, you think of things like the Eagle Nebula, that you know, Hubble has given us these great images of, but when you see the infrared, you can start seeing through it, and you see stars actually forming, stabilizing, or possibly even lighting up sometimes in there. And James Webb can look right through those types of dust clouds and see, you know, what's going on with young stars, because they haven't cleared their space around them, like our star of course has. Or you've got a clear kind of open area, and it's a little bit older system than a younger area where there's still lots of mass and gravity or mass and elements that can pull stars together that are available. [00:06:04] >> There you go. So it's kind of more like pulling back the curtains and saying okay what is going on, what can't we see with the visual spectrum? [00:06:11] >> That, and also, yeah, as we note, with the universe expanding, you get the red shift, and because infrared is the red shift. That's why it's so cold, that's why we tested it here at Johnson, at these really cold temperatures, because you need the observatory to be as cold or colder than the light you're trying to look at. Because everything, you know, our bodies give off an infrared spectrum, so if you're trying to detect something else, you don't want the observatory itself to be warmer, and that's why it's designed the say it is, why we tested it the way it is, and of course, you know, like I said, you're looking at really old, light, old, old galaxies and stars. [00:06:50] >> Yeah, you're looking at the history of the universe just by going farther and farther out. [00:06:54] >> Yes. [00:06:54] >> Fantastic. So, kind of, I mean, I really want to get into the testing too because that's like, just the kind of testing that we're doing here is phenomenal, and you're the project manager for it, so perfect person to have here, but kind of-- I wanted to, before that, go into a little bit of the history, just, you know, where this all came up, because apparently, like you said, you have Hubble, you have Spitzer, you have Chandra, you have all these great telescopes that are looking out, but this was the next step. So when did this start coming together, the James Webb? [00:07:23] >> So it used to be called the Next Generation Space Telescope. [00:07:26] >> Okay. [00:07:27] >> And it probably started like pulling together ideas, what we could do, how, what kind of requirements we needed, probably in the 90s. [00:07:39] >> Oh right! [00:07:40] >> Yeah, I would say soon after possibly the first Hubble repair mission, I want to say 95, 96 was kind of the first really pulling together of here's an architecture that we think would work for the next great observatory and then I think in 2002, they actually awarded the first big contract, north of Bremen, to be the prime contractor for delivering this telescope to NASA. [00:08:06] >> There you go, to build it. Sweet! [00:08:07] >> Yeah, to build it and of course, you know the telescope portion of it was actually managed a lot through-- by Goddard and NASA, and is being delivered to them. So I mean kind of the high risk instruments and all that was kind of a collaboration of the different contractors, but also really managed tightly by NASA and with a partnership of both ESA and Canada. [00:08:31] >> So I mean, like you said, it came shortly after Hubble, was it kind of the excitement of Hubble? And just like, whoa, these are the images we're seeing? We want more, right now, and that's what kind of sped up the process maybe? [00:08:44] >> I wish I knew the actual answer [laughter], I don't know the actual answer, but I could definitely see that that is probably, you know, a good logical reasoning, and yeah, and definitely Hubble just-- I think people were blown away even when it wasn't totally in focus, with the lens that had the astigmatism that it had. [00:09:01] >> Right. [00:09:01] >> You know, we're-- so just started looking and going hey, you know, we could spread the light out and get some great science off things we didn't know about, and then once you had the repair mission, what a, you know, huge testimony it was to the Johnson Space Center, working with other centers to, you know, go up there and repair, and now we've got a-- probably at the time, and you know, the best telescope there is, because of its location being outside of the atmosphere, and the size that it was at the time so-- [00:09:27] >> Yes! And the James Webb is going to kind of take that a step further, and we can kind of go into like, how this thing looks, because when you think about Hubble, it's like this school bus sized tube, right? That is kind of orbiting outside a little bit higher than the international space station is right now, in terms of an orbit, but James Webb is going to go further out, and it looks very different. So what's like, the make up of how James Webb looks? This is an audio podcast, so kind of describe it? I guess one of the first features that would be prominent are these shiny mirrors, right? [00:10:00] >> Yeah, so if you see the entire space craft when it's fully deployed, it has the three big segments to it. [00:10:04] >> Yes. [00:10:05] >> One they call the spacecraft bus, which is like most satellites, it's got all the communications, the power, the cooling, everything that is requiring a lot of energy, and it is facing the sun and earth, and then of course, you have the separation of that huge sunshield. The sunshield is like the size of a tennis court when it's fully deployed. You know, bigger, it's got five layers of aluminized Kapton, and that separates of course the sun and earth and moon from the last part, which is the telescope element, which we call Otis right now, which stands for OTE and ISIM, OTE being Optical Telescope Element, and ISIM being Integrated Science Instrument Module, and the two of them make OTE, because at NASA just love to take acronyms and turn them into more acronyms. [00:10:50] >> Yeah, why not [laughter]. [00:10:51] >> So that is the portion that actually has the primary mirror. So OTE is the optics. So the primary mirror. That is 18 large hexagonal segments. The secondary mirror, which is a smaller, probably still almost size of Hubble, but you know, a large-- no, not that, sorry about a two foot in diameter, another brilliant mirror that all the light is focused on, and then it goes through the center, and has a tertiary mirror. From there, it goes back and is the-- that tertiary mirror will send it to one of the science instruments. [00:11:27] >> Okay. [00:11:27] >> And so you have five different science instruments, one delivered by the Canadians, the fine guidance system, two delivered by the Europeans, and then two were developed by NASA in the United States, so... [00:11:38] >> All right, so very international kind of collaboration going on, and behind the scenes there, so it goes, tertiary right? So mirror, mirror, mirror, and then it's sending it to all of these great instruments to measure different things. [00:11:51] >> Yeah. So it's a reflective mirror. So all the lights collected on the primary, focused off a secondary and passed back through, versus like the old tube style, where it's strictly just lights coming through and passing from one to the next, and focused on a final source, you know. [00:12:05] >> Okay. So that first set of mirrors is like you said there, that hexagonal shape, they're just a series of gold-looking hexagons all kind of fitted together. [00:12:13] >> Correct. [00:12:13] >> So what was the design logic behind that? Why the hexagons? [00:12:17] >> It looks super cool, but-- when you need a mirror that big, it's really hard to produce a single monolith. [00:12:24] >> Ah. [00:12:25] >> So, even on the ground, there's like if you go to some other observatories that are more modern, that they're segmented, even, you know, ground things out like a Keck observatory in Hawaii, they have large mirrors that they've patched together, and hexagons make nice ability to kind of fit things in a nice shape, and essentially get, not necessarily a circle, but you can get the area you want covered pretty well, and make them in segments that are large, but not so big that they're difficult to manufacture. [00:13:01] >> Okay. [00:13:02] >> And then the other big thing is you know, Hubble is like two and a half meters in diameter, 2.4, or something. [00:13:09] >> Okay. [00:13:09] >> I don't know, it's larger than 2 meters. [00:13:12] >> Yeah. [00:13:13] >> And like James Webb is like six and a half meters in diameter. So it's significantly bigger you know, Hubble was all polished glass. This one is a, you know, lightweight beryllium. They used beryllium because it's really stiff, it has a great thermal performance, so you know, you know it has to get cold, beryllium tends to be very consistent as it cools down or heats up and to go to the right shape, where you think like, an aluminum pan, heating, cooling, it might bend and warp. [00:13:44] >> Yeah. [00:13:45] >> Beryllium, you know, all metals kind of change shape a little bit, but beryllium is very consistent in holding its shape, so we know they're actually perfect mirrors when they're cryogenic, and they're not perfect mirrors right now at room temperature, and that was one of the things we had to do here at Johnson was to test it that way, but-- so you know, that was one of the reasons for using the beryllium, and then of course, the gold coating was put on there, because gold does a great job of reflecting infrared light. So... [00:14:13] >> Okay. [00:14:14] >> Yeah, not absorbing the wavelength they're really looking for. So. [00:14:17] >> All right. So that's an interesting point, the way that they're designed is to be imperfect here, so when you're testing it, they're imperfect because you know once it gets to space where you want it to do all of its work is actually going to form into the mirror that you want it to be. [00:14:33] >> Correct. When it gets down to below, you know, 40 Kelvin it's essentially a perfect mirror, and that was one of the technologies that was developed on that, was you know, they polished them as perfect mirrors. They were tested at Huntsville, at the XRS CF chamber, which is where Chandah was originally tested, which wasn't big enough to test the entire telescope like we had at Johnson, but it was big enough that they could test the mirror segments. [00:15:00] >> Okay. [00:15:00] >> And map them, when they mapped them at cold temperatures, you could see, oh yeah, now it warped and moved, and is imperfect. They took it back. Purposefully polished in the imperfections. Took them back to Huntsville, and tested them again, and showed that once they got to temperature, that imperfection they put into the mirror turned out to be a perfect mirror at the right temperature, if that makes sense. [00:15:23] >> [Laughs] Yeah, no totally makes sense, you've got to design it for, you know, its ultimate destination and right now I'm sure you're looking at it just like, ah, I want you to be perfect, but-- [00:15:31] >> The other, sorry, going back to your first question-- [00:15:33] >> Yeah, sure. [00:15:34] >> About the hexagonal shape, the other big part of that is also, you know, it's launching in a rocket ferring. [00:15:39] >> Yeah. [00:15:39] >> You know, you've got an area in 5, it's a 5 meter ferring, and you've got a primary mirror that is six and a half meters in diameter so it's bigger than the rocket it's going on, and the ferring, so you had to be able to come up with a design where you would fold those wings in, and fold the whole telescope up, so that it would fit in the rocket ferring, and then of course deploy in space, so... [00:16:01] >> That's actually an interesting topic, is just the whole deployment secrets because it's kind of-- it's going to, like you said, fold in on itself, and then you're going to put it in this rocket and launch it, so actually before I go into the unfolding, where is it going to go? [00:16:14] >> So after it leaves Northrup Grumman, part of the European agreement is they're providing the rocket, which is an Arian 5, it's launching out of French Guyana in South America. [00:16:25] >> Okay. [00:16:26] >> So that's its next last destination here on earth. [00:16:30] >> Yeah. [00:16:31] >> And before it starts observing the cosmos. [00:16:34] >> Yeah [laughs], and then go out to is it-- a Lagrange Point? Or... [00:16:37] >> Correct. [00:16:38] >> And which one? [00:16:39] >> So it's an earth sun Lagrange Point 2. [00:16:41] >> Okay. [00:16:42] >> So that is about a million miles, about a million and a half kilometers on the backside of the earth, away from the sun. So it will orbit the sun with the earth. And it has about a half million mile diameter loop that it's doing. I think about 8,000 kilometers around that gravitational point. So it looks like, from the earth, it's doing this small circle, but from the sun, it's kind of doing a small sign wave. [00:17:05] >> Oh, okay. [00:17:06] >> If you see it. And so it does require a little bit of energy, but it's not perfectly staying out at one spot. It's kind of doing this really slow orbit around that Lagrange point. [00:17:18] >> Okay. [00:17:18] >> And it's a great place to be, because one, you're way out there, they're very thermally stable, because your view of the earth and the moon and the sun don't really affect its thermal performance much like you would if you're low earth orbit and once side you're on the sun, and the next time you're pretty well shaded. Basic, you know, this thing is pretty well, the part that is looking at Earth, we know the thermal input that it's going to see, in solar and then we know the backside of that sun shield, so it's also very clean. Much cleaner than, you know, low earth orbit in terms of micro meteoroids and objects like that. [00:17:53] >> Ah, right. [00:17:54] >> And it's very stable, you know, and of course the big thing too is now we're not orbiting the earth and having to protect the optics, you're just looking for as long as you want to look, and so, you know, you have to-- you're going around the sun and have to decide, okay what's my next object I'm going to look at, so-- [00:18:10] >> That's right because that sun shield is just going to be facing, you know, towards the sun the whole time, kind of blocking the light coming straight from the sun, so you've got this nice, clear view, nothing, nothing obstructing your view, and then you can kind of point it wherever you need, as long as it's not, you know, directly at the sun [laughs]. [00:18:25] >> Correct, correct, yeah. [00:18:28] >> So, but that unfolding sequence is going to be kind of cool, right, because if you look at it, it's just like this giant mirror kind of hexagon, gold thing, and it's going to unfold into that shape, and then the pole comes out, the sunshields deploy. That's going to be quite a sequence, right? [00:18:46] >> Yeah, actually the sun shields are some of the early large deployments that happen. [00:18:50] >> Sweet. [00:18:51] >> So yeah, launches, you know, first thing it does is it deploys its solar panels, starts making sure it has got plenty of energy for the rest of the trip and for the rest of the actuations, and then you know, antennas and stuff like that deploy pretty early on as well for communication purposes, and then you know, yeah, you've got that sunshield, that's, like I said, probably the size of a basketball court, tennis court, it's massive when it's fully deployed. All folded up into something that is, you know, probably less than, like I said, three or four meters in diameter, and you're going, you know, so you know, has to unfold, deploy all the sunshields, then because of the temperature difference, we actually have a deployable tower that separates the mirror from the spacecraft bus, and then it helps provide, again, a long length for some thermal isolation there. [00:19:46] >> Oh! [00:19:46] >> And then once all that is done then, you know, the secondary mirror would deploy, and the primary mirror would finish out. And then there's a few more radiators on the actual spacecraft by the science instrument, on the telescope portion that would continue to do some deployments until it's out there. But there's about two weeks of deployments. I think there's 183 actuators that are going off, I mean it's a lot. [00:20:14] >> Yeah. [00:20:15] >> Things happening and a lot of anxiety [laughter] to go out there, it takes about 30 days to actually get from French Guyana to L2. [00:20:24] >> Okay. [00:20:25] >> So it's like 29-- [00:20:26] >> Thirty days to get to L2, and then-- [00:20:29] >> Yeah, about a month. [00:20:30] >> And then you've got another how long until it's fully deployed? [00:20:34] >> So on its way out there it is deploying. [00:20:36] >> Oh, I see. [00:20:36] >> So yeah, it's doing most of its major deployments on its way out there, allowing the mirrors to cool, and-- [00:20:42] >> Okay. [00:20:43] >> And so yeah, you've got about two weeks of hoping everything goes well, and then like I said, another month to make sure it's actually getting into the right orbit, or about a month to make sure it's in the right orbit, and then from there it starts taking images, and then hopefully the scientists will tell us when they think they've seen the first light of the universe and start sending back really cool pictures. [00:21:09] >> Yes, I'm very excited for that for sure, but I'm sure that whole trip is going to be very, very stressful [laughter]. [00:21:15] >> Yeah. [00:21:16] >> A lot going on there. But just the mission itself is just phenomenal, like what it's trying to do, and then the amount of work going into it, just all over the U.S. and is it being tested outside the U.S. too, or is it just being launched from outside the U.S.? [00:21:32] >> It's just being launched from outside the U.S., so like I said, two of the science instruments were delivered by corporations under ESO, so European companies, and so they were-- you know, they had to go through their own certification program, but they were eventually all integrated into the final science package, and that went through its thermal document testing up by Goddard-- [00:21:55] >> Oh, okay. [00:21:55] >> So yeah, they're SES chamber there, and like I said, a lot of the meter development work was done using Hubble, I mean, excuse me, the Chandah facility there, the XRCF at Huntsville. [00:22:06] >> Okay. [00:22:07] >> The mirrors have traveled all over the United States, you know, mirrors, technology was really, I think developed by Ball Aerospace in Boulder, Colorado. They did testing there as well. So, I mean the mirrors went from the company that polished them in California and San Francisco to testing at Huntsville, to be back to California to be re-polished, to testing in Huntsville, to be fully integrated with all their actuators to be tested at Huntsville, to be, you know, sent to Goddard, to be integrated as a system, then, you know, down here to Johnson, out to Northrup Grumman, and so I mean, the mirrors have traveled the United States, and you know, quite a bit, and like I said, then like I said the science instruments, some were from Germany, the Netherlands, and Ireland, were all in collaboration as part-- under ESA to deliver stuff, and then the Canadian space agency delivered a fine guidance system. Those parts were tested up in Ottawa, at their CSA facility there, in their chamber, so-- [00:23:12] >> Wow. [00:23:13] >> So a lot of work throughout the United States on this. [00:23:17] >> Yes. [00:23:17] >> KPL is managing the cryocooler that is used for the mirror instrument, and that is the longest wavelength that they're going to be looking at. [00:23:24] >> Okay. [00:23:25] >> And so it's the coldest, so it actually runs about 5, 6, 7 degrees Kelvin. [00:23:30] >> Whew! All right! [00:23:30] >> And yeah, when we were doing our testing we were at 20 degrees, so you know it's like minus 4, 23 Fahrenheit, there, really close to absolute zero. [00:23:38] >> Yeah! [00:23:38] >> So yeah, looking at really long, older wavelengths. And you know, that's stuff that has never been observed before, would be really interesting to see what shows up in that spectra, so. [00:23:48] >> Exactly. It's just amazing what you can find just from some of these telescopes now, I mean, they're discovering planets just by these small dips in light and you can discover, you know, planets now, there's hundreds of exoplanets that have been discovered all over the universe, so looking at the beginning of the universe and things that have not been looked at before, it's just an exciting concept. [00:24:09] >> Yeah, you know, and speaking of that, of course, one of the science objectives of James Webb now is looking at planets. Not necessarily looking for planets, but it would look at planets, be able to-- it's going to look within our solar system for traces of water, and carbon type structures, on the different planets, and how, you know, maybe some type of ring that maybe exists within our solar system, then be able to look for that in other solar systems, and go oh! There's signs of, you know, life-giving properties around the solar system, and then it can also look at planets, and look at the spectra around that, and tell you maybe what an atmosphere is made of, and hopefully, like I said, maybe discover a planet that has water, nitrogen, oxygen, type of you know, things that would show signs of life, you know, carbon dioxide and things like that. [00:24:55] >> Okay that's exciting [laughter]. [00:24:57] >> It's really exciting, yeah, yeah. So yeah, so it's, you know, it's got that kind of the four major science objectives, you know, the first light, the evolution of galaxies, birth of stars, and the existence of possible life on exoplanets, and stuff like that. [00:25:18] >> Wow. Yeah! [00:25:18] >> So science tool, really, hopefully will expand our human knowledge of what our universe is and what's around us and our solar system and galaxy and beyond, so-- [00:25:30] >> Unbelievable. What a resume for the James Webb space telescope [laughter] to say what you're going to accomplish. But you kind of hinted toward some of the testing already, and just all these parts coming, you know, first of all, traveling all over the U.S., but then all coming together. You know, what's the story there? You have all these different places, I'm sure they're manufactured in different places, right? [00:25:52] >> Correct, so yeah, so you know, Goddard is where the program is managed out of, the project office is managed out of. [00:26:01] >> Okay. [00:26:02] >> You know, they're responsible for pulling it all together. Well they, again, this telescope element, they pulled all that together, so you know, all the science instruments and the ISIM package was delivered to Goddard, they tested it. And then all the components that make up the telescope were delivered there, and our [inaudible] facility, which is their huge clean room, they assembled James Webb. So it's got the carbon fiber back plane, all the radiators, all the wiring was done, you know, everything was finally assembled there, and they'd all been tested at component level, but never tested at a system level. So, they did test it at a system level, in terms of just its vibe and acoustic, to make sure it could survive, you know, launch-- [00:26:42] >> Yes. [00:26:43] >> But they could never test a full optical path and everything like that. So that was one of the main reasons of coming to the Johnson Space Center, as here is where you could actually simulate where it's going to be out in orbit, and now that you've tested all these other smaller components, and smaller chambers, you know, you could test a full system in a large thermal vacuum chamber, and still get to the deep space thermal conditions and vacuum conditions, and so-- [00:27:08] >> Yeah, so it got all assembled, all these different components tested, you know, use that other component levels, constructed at Goddard, and then from Goddard it was tested, and then it went to Johnson or did it kind of go around from there? If it's-- so it's right from Goddard to Johnson. [00:27:22] >> So yeah, so this large portion of the telescope went from Goddard to Johnson and from Johnson it's going to Northrup Grumman, so this is its last time it is with NASA when it leaves here. [00:27:33] >> Oh really? [00:27:34] >> Yeah, from there it goes to Northrup Grumman, who is the prime contractor, to be integrated with the rest of it, and like I said, it goes from there to the European space agency's launch facility at French Guyana, but yeah, so it's kind of a mixed feelings, I mean, you know, it has been nice having it here at two different NASA centers for the last few years, but it's-- [00:27:56] >> All right so it did, you said, acoustic testing at Goddard, right? [00:28:00] >> Correct. [00:28:01] >> And just to make sure the launch is going to be okay and everything kind of checked out there, right? So-- [00:28:05] >> Yeah, the vibe and acoustic was a very big deal, you spend lots of money then shake something really hard that you treat with, you know, kid gloves [laughter] for all the rest of the time, and now you're-- you see this test where you're actually just shaking it, and parts are just going all over and then you at least do some type of verification to make sure everything looks like it has survived and ready to go, so-- [00:28:26] >> All right, and they got the thumbs up, and then it came here. [00:28:29] >> Then it came here. [00:28:29] >> All right, so then what the big question, you know, your area of expertise, what was the testing that went on here? How did that, when did it come in and all that kind of stuff? [00:28:38] >> I'm not sure how far back you want to go but [laughter]-- [00:28:41] >> Be here forever. [00:28:42] >> Yeah, so the flight article got here in May of last year. [00:28:46] >> Okay. [00:28:46] >> May 2017, but we had been working with Goddard probably from 2004 in terms of hey this looks like the right chamber to do what we need to do for a thermal vacuum test, you know, but they had really different requirements from what the chamber was originally designed for, which was Apollo. [00:29:06] >> Yeah. [00:29:06] >> They've got contamination, vibration, and the thermal and test duration were way different than what Apollo needed, which was fast, fairly quick, redundant type of testing with human rated, you know, really protecting the crew and the capsule, and doing a thermal simulation of going to the moon and back. And you know, here, they're like, you know, they don't care about the heat. I mean, we did, because we did need to test the sunshield and some of those thermal paths, and we did do that in Chamber A, but for the most part, the telescope all have seen just the cold of space, and that's what we simulated for that. [00:29:45] >> Okay, I should probably ask, what's Chamber A? [00:29:48] >> So, yeah, Chamber A is a large thermal vacuum chamber here at the Johnson Space Center, in Building 32. So there's two chambers in that building, A and B, you know, both were Apollo era chambers, and have continued to serve NASA over the years. Chamber A is ten times the volumetric size of Chamber B, and it's about 65 feet in diameter, about 120 feet from top to bottom. [00:30:15] >> Wow, it's huge! [00:30:16] >> Yeah, it's huge! So James Webb was in a shroud that was about 45 feet in diameter, and about 70 feet tall. That put it in the thermal conditions it needed. Like I said, in there, we made a lot of modifications, both from the Johnson side, and from Harris, which was formerly kind of Kodak was responsible for the optical testing, so we integrated all kinds of optical test equipment into the chamber as we were constructing some of that and testing it through the years, so that we are kind of starting about 14 really commissioning the chamber, and starting to integrate the-- in commissioning the GSC, and then doing a test series we call the pathfinder, from in 15 and 16, that really had a-- the engineering unit of James Webb, with the two primary mirrors, secondary mirror, and a way to kind of at least pick up light where the science instruments were. [00:31:14] >> So we could do a full series of testing to test the system, and verify that we were going to be testing the telescope and not the equipment we designed to test the telescope. [00:31:26] >> Yes! [00:31:27] >> So yeah, it kind of was a shakedown series of tests. We learned a lot from that too. To really kind of reduce risk, change our plans of operations, and just improve our system reliability and stuff like that. [00:31:41] >> Yeah! [00:31:41] >> So it was really helpful! [00:31:43] >> [Laughs] So you kind of put this sort of, I guess "pretend" James Webb inside to see, all right, let's see how this reacts and get it ready for the real James Webb, because like you said, Chamber A was not designed to test James Webb, it was designed for human missions, and they put human vehicles in there, I think the lunar module, and stuff like that, right? They actually tested? [00:32:07] >> In Chamber B, yeah. [00:32:08] >> In Chamber B, they tested? The lunar module? [00:32:10] >> Yeah, Chamber A was the service command module so that's where you had, yeah, but Skylab was in Chamber A as well. [00:32:15] >> Oh, okay. [00:32:15] >> And then of course it has continued its use for just, you know, development of shuttle and space station and stuff like that, in terms of more hardware than human testing, so-- [00:32:26] >> Yeah. [00:32:26] >> So you know, whenever you need a large thermal vacuum chamber, it's one of the very few that exists, so you know, it's a great asset for NASA to have something like that. [00:32:36] >> So you started gearing it up for James Webb testing in 2014 you said or was it before that? [00:32:42] >> So we had to modify the chamber quite a bit. And the big years for that were in 2009, through about 2012. [00:32:48] >> Oh okay. [00:32:48] >> We actually replaced the pumping systems, especially the high vacuum systems, because all of them were, had oil type of system, or oil within them or an oil pumping system. Everything, we couldn't have any type of oils around James Webb. So everything went through like a real clean, newer technologies. Our thermal systems used to only kind of get to about 100 Kelvin, and we needed to be able to get to about 15 Kelvin, and then, of course, we ended up just testing at 20 Kelvin for James Webb, but still we wanted to be able to, you know, kind of exceed that requirement or meet it, so 15 was kind of what we thought we'd need to-- so we had to put a different shroud in, and use helium as the cryogen for cooling it down instead of like the 100 Kelvin that is probably more liquid nitrogen type stuff, but with that, too, you know, the chamber had no vibration isolation, so at the top of the chamber now, we have a series of vibration isolators, everything was suspended in the chamber, so when we were testing James Webb, all its primary optical test equipment was sitting above it that was mapping the mirrors, that was reflecting the light, and then the telescope was hanging below, and then all that was in a single kind of optical bench system that was supported outside the chamber on these vibration isolators, and the nice thing is that sitting down below that, so the mass is well below the vibration isolation, and one of the nice things, still about Houston is we didn't have zero issues with vibration. [00:34:20] We definitely had some issues with vibration, but because we're not on bedrock, we sit on like [chuckling] you know, mud and gumbo. Yeah, you know, we can park a tractor trailer on the backside of the building and take LM2, and we don't tend to see any of those vibrations carrying through to the chamber, so-- [00:34:39] >> Oh! [00:34:40] >> So that was a, you know, a big, kind of deciding factor versus a facility that is built on bedrock, and you can feel things from all over and miles and miles away, and it's really hard to get a quiet environment. We kind of-- there's not a lot of benefits, I think, like I said yeah, swamp, but it worked really good in terms of creating a real quiet atmosphere for testing. [00:35:02] >> Yeah, so that was one of the selling points, then for bringing it to Johnson was, you know the fact that it's not sitting on Bedrock, the fact that it can provide a quieter and less vibrating kind of environment. [00:35:13] >> Yeah, absolutely, I think that you know, the quiet environment, the size of the chamber was this Goldilocks in terms of the focal points, focal length of the primary mirror system, so we were able to design reflective mirrors at the top of the chamber, and have what we call the center of curvature optical assembly, which was the main piece of test hardware in the chamber, that did the mapping using interferometry of the primary mirrors, and make sure that, yeah, like I said, these 18 segments that are-- we started them all in like a launch lock position, they have to release, and they have to kind of move and act as a monolithic mirror, so you got-- that was a big thing we had to test is, hey, will this thing go to its right shape and make sure that it looks like a monolithic mirror, and not a bunch of individual mirrors or ones out of phase, or something like that. Yeah, because then you won't get a clear image, right? [00:36:06] >> Yeah, clear image, or you're losing some of the capacity of like some of the mirrors are not, you know, reacting correctly, so-- [00:36:13] >> So a lot of new technology was developed on those algorithms, and the software to position and tell the mirror like how to behave, so it was, it was very successful. Like I said, it was very successful, but really extremely complex, probably one of the most complex thermal vacuum tests that have ever been carried out. [00:36:33] >> Yeah, like you said, years in the making, you started conversations in 2004, and by 2009, you were already getting this thing ready to go for James Webb, right? [00:36:41] >> Yeah, we were, yeah tons of metal was cut and thrown away and new [laughter] equipment was coming in so... [00:36:47] >> Yeah, and not just the thermal vacuum chamber, right? You were also doing the area outside to be a clean room too. [00:36:56] >> Correct, so that kind of started right after we finished the chamber in 12, kind of the clean room picked up in early 13, and well, that happened pretty fast. I think by sometime in the middle of 14 that was done. And like I said, really has been an exceptional clean room, we were given a certain, you know, budget for how dirty the mirrors could get while they're sitting here, you know the longer something sits around, it's going to just collect, and you know, you're given this budget, and we actually stayed well under that budget. Of course we were able to use this last, probably week and a half to do a final cleaning of the mirrors prior to it being shipped to Northrup Grumman, so it's leaving Johnson cleaner than when it arrived, so that's pretty amazing. [00:37:39] >> That's awesome. [00:37:40] >> Yeah. [00:37:40] >> I'm sure, well, so I'm trying to imagine the environment that you guys are in, so you're testing it, you're in this clean room, everything is like super spotless, probably one of the cleanest places in the known universe [laughter], I don't know but it's super clean. You guys are kind of outfitted with these white garments, right, that are head to toe, make sure no dust or hair or anything is getting on these mirrors. [00:38:02] >> Yeah and usually, you know, human, you know dust, is typically like, you know, some type of human fallout type of thing, so you know, hair, skin cells, and other things like that, are probably the major sources of dust, so yeah, reducing that and monitoring that is a big deal, and of course everything on the spacecraft is real ESD, so everybody is outfitted with, you know, electrostatic type of wristbands when they're working on anything around there. You know, so yeah, it's a full head to toe garment that are [laughter] quite a bit, you know, it takes a good amount of time to get suited up when you go in there. [00:38:45] >> Yeah, I can imagine! Especially because of the requirements, that it has to be, you know, what's the level of, like you said, the level of clean that is acceptable. So and I'm sure that cleaning the mirrors is a whole process in and of itself, right? You're not just going to be spraying it with Windex and kind of wiping it down, right? [00:38:58] >> Not that was, you know, the contamination team led out of Goddard, you know, managed that effort, and it was very arduous task, that they mapped each of the mirrors, and you're mapping probably like a few inches at a time, so-- [00:39:14] >> Oh wow! [00:39:14] >> Yeah, they're cleaning a very small area, black light it, high resolution light it, and look for any type of, you know smudge or any dust particles, and they carefully, like, anytime you could, you know, get a dust particle, try to remove it and with a small brush or something like that, but it was really, I was surprised at how detailed they were and how they handled it, but we're done now, and like I said, all the mirrors are actually quite a bit cleaner now than when it first got here, so. [00:39:46] >> All right. So you said now it's kind of wrapped up and ready to ship off to the next place, right? Or are you still in the process of wrapping it up? [00:39:53] >> No, no, we completed all the-- so you know, we had the big family day [laughter], that was a huge success and-- [00:39:58] >> Yeah. [00:39:59] >> The 20th, then we repeat it on the second. But on the third we really started doing the stowing, you know, the opposite of deployment. So we stowed the mirror wings. Stowed the deployable tower, and really got it ready for shipment soon after that, so when once all those stowing sequences were done, we began the cleaning process so really there is not a lot left to do except for take it off its turnover fixture and get it into a shipping container, and that is planned for tomorrow. [00:40:36] >> Wow, this is exciting! All this kind of [laughter] preparation you know, you said, talking so early, then kind of preparing the chamber, you did it, you tested it, you did it, you know, like you said under budget, and it was successful so, I mean, actually that is a good question, how did the tests go? [00:40:52] >> Oh, the tests went really well [laughter], so the thermal vacuum test, the main part test, we call it, the Otis Cryovac Test. Started in early July and we were under vacuum for about a little over 100 days, so yeah, we had people round the clock. Even before then, but you know, the people operating our chamber from Johnson were probably on shift for about 102, 103 days. Took about 30 days to cool the spacecraft down to its flight like-- took 30 days for the chamber to get down to temperature, it could have gotten much faster, but this provided the profile they needed. [00:41:36] >> Okay. [00:41:36] >> It took about 40 some days for the telescope to really start getting down to its flight like temperatures and start doing, start firing up the science instruments, which were really sensitive to heat, and stuff like that. [00:41:49] >> Yes. [00:41:50] >> Of course once we were down and just get cold, you know, Harvey shows up and-- [00:41:57] >> Oh! That beast! [00:41:58] >> Yeah, so, but it was-- we had a lot of plans in place, and we executed those plans, and got a lot of support from the center to keep things going and a lot of support from Goddard. Everybody kind of pulled together, unfortunately. Some people didn't get to go home for many, many days-- [00:42:15] >> Oh no! [00:42:16] >> Because they couldn't find a path to their home or-- [00:42:20] >> That's right, a lot of the gates were-- [00:42:22] >> Yeah, relief could not leave their homes and get to work, so, but we had a lot of preparations for people to be able to do that, and from the Goddard perspective, you know, their team was here, locally and in hotels, and they were able to get some of the best optical testing done during that time, so-- [00:42:39] >> Wow! [00:42:40] >> Yeah, yeah, so all the optical tests were done, I think they exceeded their requirements on all their stuff as well, so they really feel like the performance of the telescope is great. They're delivering a product now that they really believe is going to do its mission. [00:42:56] >> Fantastic, yeah, you have been kind of through the wringer since it's been here, huh? You had Harvey and just like last week we had that ice storm, so yeah, you've really encountered a couple challenges, but you did it. That's-- that's quite an accomplishment. That's really cool. [00:43:09] >> Thank you. Yeah, it's been a huge-- the team here at Johnson has been very dedicated to the success of the mission and the team that has been down here, the international team, we've had hundreds of people from ESA and stuff supporting this, and everyone is extremely dedicated and really believes in what they're doing, so. [00:43:29] >> All right. That is so awesome, so I kind of wanted to clarify one point is, you know, I think we kind of just sort of skipped over it, but Chamber A is unique in the fact that, or maybe not unique and you can clarify this, it's a thermal vacuum chamber. [00:43:44] >> Correct. [00:43:44] >> So not only does it bring it down to, you know, the pressure of space, but it's also bringing it down like you said 15 Kelvin, but I guess you're testing it at 20 Kelvin. [00:43:52] >> Yeah. [00:43:53] >> Super cold. I don't think people understand how cold that is, 20 Kelvin. [00:43:58] >> Yeah so 20 Kelvin is about -423 Fahrenheit, I mean, it's cold enough that the only molecules that are moving are probably some hydrogen and helium and maybe some neon, and there is not much of that, because we have some pumps that work really well to try to get rid of that, those molecules, so there's not a lot of-- we just tell people like, when we're at room-- sea level pressure, there is about 30,000 pounds of air in that chamber, so you know, you think air doesn't have that much mass, when we're down at test temperatures, there is the mass of about a half staple in the chamber [laughter], that's what the mass of all that air is remining, so to create that space-like environment. And then like I said temperature wise, like I said all the nitrogen, oxygen are normal air you breathe, instantly freezes out when it comes in contact with the surface that cold. [00:44:57] >> Whoa! [00:44:57] >> So it's just really cold [laughter], it's hard to imagine, you know, yeah, there's not much moving around at those temperatures. [00:45:06] >> Yeah, it's just kind of when you say it the way that you say it, it's kind of surprising to think that anything works in that kind of environment, but if you think about it, there is, you know, satellites and probes all over the solar system that we've been sending, and now we are just, this is just, this is another one that is a little bit, you know it's big, and it's got a lot of-- it's got a lot of elements to it, but the fact that it is, you know, you can fire up the instruments and they worked, right? [00:45:29] >> Oh yeah. [00:45:30] >> The instruments-- [00:45:32] >> Yeah, all the instruments worked. [00:45:34] >> Yeah. [00:45:35] >> You know, so a lot of the instruments had been tested, the package was tested at Goddard, like I said, but you know, never tested as a system where, and same with the primary optics, they'd never been fully assembled and tested as a system so it was really a big deal to be able to test the primary mirror, make sure the primary mirror is acting correctly, then the secondary mirror, then actually send light all the way to the science instruments, and you know, oh yeah, you had a simulated star, and it is tracking it correctly, and it is what you simulate and are sending is what is being received, and so now you know all the elements are where they're supposed to be, and in focus, and you know, because you're talking a little, you know, probably...the thickness of a hair was way out of focus for a mirror like this, you know, so everything has got to be really tight alignment, so. [00:46:26] >> Yeah, yeah. Like literally 99% on this test is an F, so yeah [laughter]. [00:46:32] >> Yeah, that's a good way of putting it. [00:46:33] >> Yeah, so that's kind of cool, you simulated it looking at a star, as like you kind of, all right, put it through this pretend environment. Not only are you testing if it can survive the pressure and the cold, but also let's fire everything up and see if this thing can actually see stars. [00:46:50] >> Correct, yeah, yeah. You know, like I said, the first thing we had to do is of course make sure the primary mirrors look like a monolith. [00:46:58] >> Yes. [00:46:58] >> And then once those things we know, yeah, okay that looks right now, the primary mirrors and secondary mirror, are they aligned together, and then the tertiary mirror, then the science instruments, you know, and the thing has got a small amount of movement to be able to correct, you know, that type of stuff, because everything is moving a little bit, and with the temperature, so that's a big difference between this and Hubble. This, all the mirrors have some degrees of freedom to be able to slightly move, so they've got actuators on them, allowing you to adjust their focus, or adjust their position slightly. And so that was part of the testing was being able to make sure that all that does, works, and then some of the more challenging testing is what we, you know, would be like a pass and a half where we actually had like a fiberoptic that would simulate like a star, a point of light, and you would bounce that off the primary mirror or off the secondary mirror, back off the primary mirror, off our test mirrors, at the top of the chamber called auto-collimating flats, and then back through that entire path, then to a science instrument [laughter], so everything had to pass at least the primary optics twice, and some of the, you know, off the science instruments you know, once, and like I said any slight vibration or anything like that disturbs the image, and so you know, you had that-- everything worked really well, like I said, you don't realize hoe a little bit of shaking or something like that can really blur a point of light when you're trying to look at a few photons and stuff like that, that the telescope is supposed to be observing, so. [00:48:31] >> Yeah, that's right, and you got an A on that test right [laughter]. [00:48:34] >> Yeah, I mean, everything-- I'm not an optical guy, but it was kind of fun to come in every day, we had typically every afternoon we had meetings, and we could hear the optical guys, like that's the first time we ever tested this? Yeah! And you're like almost every day was like a party during the test because [laughter] it was the first time they had done system level tests and completed an objective that, you know, they're very excited, like the performance. [00:49:00] >> All right, I should have been hanging out with you guys every day as a party, that's pretty cool [laughter]. Cool. But yeah, just to see the things, like you said, that you've been working on for so long, to come together, and you fire them up and they work, I can see that being like oh my gosh, yes! Yes! This is doing what I wanted it to do! [00:49:15] >> Yeah! And that was like, so on the from the Johnson Space Center standpoint, it's kind of almost a little bit benign, because we had already wrung out our chamber and created-- got rid of a lot of issues we had there, so you know, we were able to create this environment, like when we had the hurricane came, and all the rains and floods, we had some issues with the building, but the telescope never knew anything was going on [laughter] because all the facility systems operated as we wanted them to, and we really never lost anything, so you know, it wasn't the same excitement for us as it was for the telescope, because we had ben doing a series of testing, and got rid of all our bugs, so it's almost like one of those things, like boring testing from creating the environment, and doing all that is a good thing because we don't want to be testing any of our stuff out, or having any issues with our stuff, when we're really trying to test the telescope at this point, so it was great to ring all that out, and see their excitement, as they were able to test the telescope and really get to an understanding to really prove that optically it is working as they expected, and all the little requirements that pass down from some type of science objective, were met. [00:50:23] So-- [00:50:23] >> Yes, and that means that you did your job, right? You provided the environment for these guys. So. [00:50:29] >> Yeah, the team here at Johnson did. [00:50:31] >> Yes, you and your team. Absolutely. Fantastic. Very exciting! So you're wrapping up testing, it's all wrapped up and ready to go off to its next point, so what are the next steps until it is launched? It's going to Northrup Grumman next? [00:50:44] >> Yeah, it goes to Northrup Grumman, and at Northrup Grumman it would be integrated with the sunshield and the spacecraft bus. Once it's integrated, I think it there goes through a series of vibe and acoustic tests, then they have to do a deployment test, one more time, they really want to make sure that after they simulate a launch, you can do the deployments. The sad thing about it is that it probably takes about two months to re-stow everything, you know, it's really, you know, a lot of inspections along the way to make sure that everything is folded back correctly. [00:51:20] >> Yes. [00:51:20] >> And all the actuators are reset correctly and then it should be ready to ship out to the launch pad from there. [00:51:29] >> All right, so one more stop and then it goes off to launch. And when are we ending for again? [00:51:33] >> We are no earlier than March of 19, which would probably be more like summer time I'm thinking and 19 is probably where it's landing. [00:51:42] >> Okay, all right. Very exciting! Yes! [00:51:44] >> It is, it is. [00:51:45] >> Then it's going to go out to L2, and we're going to see the beginnings of the universe, and all those, that awesome resume of cool things [laughter] exoplanets, the formations of galaxies, and you said stars too right? [00:51:56] >> Yeah, I'm expecting to see, like same things you saw from Hubble. [00:52:00] >> Yeah. [00:52:00] >> You're going to start seeing coming from James Webb, and lots of physicists are going to hopefully just see stuff that they didn't even expect to see [laughter] and try to explain it to us, so I'm really excited about what it's going to do, and-- [00:52:14] >> Fantastic. Well, Jonathan thank you so much for coming on, I know this is kind of at the end of your testing cycle, and you just have a couple more days until you can say yes! Done! [Laughter] And hands off! So I really appreciate you coming in while it's still here, and you are kind of, I can see the excitement where you're like yes! We did it! I mean, there's still steps to go, but congratulations to you and your team for the successful testing here, and I just can't wait to see this thing launch, and see the beautiful images come back. [00:52:42] >> Thank you, I'm excited as well. [00:52:44] >> Awesome. [00:52:45] [ Music and Inaudible Speaking ] [00:53:09] >> Hey! Thanks for sticking around. So today we talked about the James Webb space telescope that was here just about two weeks ago at this point, and we just wrapped up testing here in Houston, but it's off to Northrup Grumman, and there's a lot of testing ahead, but eventually it will be launching into space, and sending some beautiful images back to earth. So if you want to see some of the cool testing going on with Webb throughout its journey until its launch next year, you can go to NASA.gov/web. That's a great resource for all the testing and all of the latest checkmarks and milestones that we're crossing as we get toward that launch point. You can also go to wwww.jwst.nasa.gov, that is Goddard Space Flight Center, but like Jonathan said, that is where the project was managed out of, so there is pretty cool stuff in there, and it's actually a pretty interactive site. It's pretty cool. On social media, we are pretty active, too, in the James Webb space telescope as well, on Facebook, it's NASA's James Webb Space Telescope, or at web telescope. On Twitter, it's at NASA web, and on Instagram, it's also at NASA web. [00:54:14] You can find out some of the latest updates there as well, otherwise you can go to the NASA Johnson Space Center sites on any one of those platforms. We see these all the time, guys, you should be following us by now. I know you are, because you love us, and we love you. So here's the hashtag ask NASA on the Johnson Space Center accounts, to submit question or idea for the podcast, and we will make sure to mention it in one of the later episodes. Just make sure to mention it's for Houston We Have a Podcast. So this podcast was recorded on January 25, 2018. Thanks to Alex Perryman, Kelly Humphries, and Jenny Knotts. Thanks again to Mr. Jonathan Homan for coming on the show. We'll be back next week.

In this issue, ASK writers explore ways to maintain their balance in their field of Project Management, and even what happens when they don't. From his own experiences. Colby Africa learned that pushing too hard can take a personal toll, even though his project was a success in the end. He looked back and asked himself. At what personal cost? Sometimes one of the most simple - and the most human way - of keeping oneself grounded is not to lose your sense of humor. Ray Morgan's story about a test flight gone bad tells how the sound of their model crashing to the ground was followed by the test team's hysterical laughter. The story, you will see, is much deeper. But the message in the example? Sometimes for no fault of our own. things just don t go as planned. One way of dealing with it is to be able to laugh at ourselves. Of course. a setback itself is not to be taken lightly, but a leader capable of lightening the moment is more likely to set a positive tone for the try, try again. Staying optimistic is important for team morale. specifically when a project is dealt a huge downsizing blow. After his project was cut significantly, Tom Sutliff was able to show his team that all was not lost and to help them focus on the fact that they still had a job to do. He had to balance the new project requirements with the fact that his team had been committed to the original prcject and would be personally affected. He stood back, got a new perspective. and upheld the positivity needed to lead them effectively. Even when you keep your chin up and work to the best of your ability, things still go wrong. It's human nature. People train for years to make it to the Olympics and blow their shot during one crucial second in the spotlight. For Marty Davis, his crucial second was when the contractor dropped his 3,000 pound spacecraft. Rather than point the finger at those around him. Marty stood up like a true leader and acknowledged what he could do better if ever in this situation again.

Relations of Dispositions toward Ridicule and Histrionic Self-Presentation with Quantitative and Qualitative Humor Creation Abilities.

PubMed

Renner, Karl-Heinz; Manthey, Leonie

2018-01-01

Previous research has shown that humor and self-presentation are linked in several ways. With regard to individual differences, it turned out that gelotophilia (the joy of being laughed at) and katagelasticism (the joy of laughing at others) are substantially associated with the histrionic self-presentation style that is characterized by performing explicit As-If-behaviors (e.g., irony, parodying others) in everyday interactions. By contrast, gelotophobia (the fear of being laughed at) shows a negative correlation with histrionic self-presentation. In order to further contribute to the nomological network, we have explored whether the three dispositions toward ridicule and laughter as well as histrionic self-presentation are related to humor creation abilities. In doing so, we have assessed the four constructs in a study with 337 participants that also completed the Cartoon Punch line Production Test (CPPT, Köhler and Ruch, 1993, unpublished). In the CPPT, subjects were asked to generate as many funny punch lines as possible for six caption-removed cartoons. The created punch lines were then analyzed with regard to quantitative (e.g., number of punch lines) and qualitative (e.g., wittiness of the punch lines and overall wittiness of the person as evaluated by three independent raters) humor creation abilities. Results show that both gelotophilia and histrionic self-presentation were positively correlated with quantitative and qualitative humor creation abilities. By contrast, gelotophobia showed slightly negative and katagelasticism no associations with the assessed humor creation abilities. These findings especially apply to the subgroup of participants that created punch lines for each of the six cartoons and partly replicate and extend the results of a previous study by Ruch et al. (2009). Altogether, the results of our study show that individual differences in humor-related traits are associated with the quantity and quality of humorous punch lines. It is argued that behavior-related or performative humor creation tasks should be considered in addition to the CPPT in order to open up new avenues that can cross-fertilize research on individual differences in humor and self-presentation.

Common psychotic symptoms can be explained by the theory of ecological perception.

PubMed

Golembiewski, Jan Alexander

2012-01-01

The symptoms of psychiatric illness are diverse, as are the causes of the conditions that cause them. Yet, regardless of the heterogeneity of cause and presentation, a great deal of symptoms can be explained by the failure of a single perceptual function--the reprocessing of ecological perception. It is a central tenet of the ecological theory of perception that we perceive opportunities to act. It has also been found that perception automatically causes actions and thoughts to occur unless this primary action pathway is inhibited. Inhibition allows perceptions to be reprocessed into more appropriate alternative actions and thoughts. Reprocessing of this kind takes place over the entire frontal lobe and it renders action optional. Choice about what action to take (if any) is the basis for the feeling of autonomy and ultimately for the sense-of-self. When thoughts and actions occur automatically (without choice) they appear to originate outside of the self, thereby providing prima facie evidence for some of the bizarre delusions that define schizophrenia such as delusional misidentification, delusions of control and Cotard's delusion. Automatic actions and thoughts are triggered by residual stimulation whenever reprocessing is insufficient to balance automatic excitatory cues (for whatever reason). These may not be noticed if they are neutral and therefore unimportant or where actions and thoughts have a positive bias and are desirable. Responses to negative stimulus, on the other hand, are always unwelcome, because the actions that are triggered will carry the negative bias. Automatic thoughts may include spontaneous positive feelings of love and joy, but automatic negative thoughts and visualisations are experienced as hallucinations. Not only do these feel like they emerge from elsewhere but they carry a negative bias (they are most commonly critical, rude and are irrationally paranoid). Automatic positive actions may include laughter and smiling and these are welcome. Automatic behaviours that carry a negative bias, however, are unwelcome and like hallucinations, occur without a sense of choice. These include crying, stereotypies, perseveration, ataxia, utilization and imitation behaviours and catatonia. Copyright © 2011 Elsevier Ltd. All rights reserved.

The making of female fertility. Anthropological perspectives on a bodily issue.

Talle, A

1994-04-01

The cultural and social context of sexuality among the Maasai of Tanzania was described based on case studies, focus groups, interviews, and observation. There were about 300,000 Maasai concentrated along the border with Kenya who engaged in livestock herding. Distinctive features of this agricultural group were age hierarchies and power relations between men of various ages. The formal system determined gender relations and the passage into womanhood. Boys were circumcised at about 16-18 years of age, which marked their entry into the warrior age set system. During the next 7-8 years these young adults lived separate lives in all ways (location, dress, diet, and code of conduct) and were under the authority of the elders. Young men were not allowed to marry or to engage in sexual activity with married women. Through rituals, the young men developed strong bonds. The cultural meaning of sexuality emphasized physical strength, nutritious food, and good health. Premarital sexual activity occurred between warriors and prepubescent girls aged 10 years and older at special homes or in secret places. The aim was not pleasure but experience. The emphasis was on the number of partners and the number of ejaculations. Penetration was achieved gradually and under the direction of mothers; care was taken not to physically harm the girls. Girls selected their sexual partners and publicly announced their selection at a ritual milk drinking occasion. Girls without male partners were subjected to forced penetration amid laughter. There was never any shame or guilt, unless brothers were present. There was genital openness, but not lewdness or depreciation. Virginity was not important, not considered an embarrassment, and signified someone without interest in the opposite sex. The early sexual debut was considered necessary for the girls' health and breast development. Girls were circumcised at 13-15 years of age. After circumcision, the girl was allowed to marry, which brought with it restricted sexual behavior. Many married girls have revolted against the patriarchal system and engaged in secret, illicit sexual relations. Uncircumcision was construed to mean infertility and the possibility of deformed children. The womb was considered the source of life.

The effect of medical clowns on performance of spirometry among preschool aged children.

Medical clowns (MCs) are known to assist in reducing pain and alleviating anxiety. The objective of this study is to evaluate the ability of MCs to assist preschoolers in performing spirometry. A prospective, randomized controlled trial. Children aged 3-6 years participated. After a first spirometry, children were divided into two groups: the first performed a second spirometry with an MC. The second repeated spirometry with the technician. Primary outcome was second spirometry values compared between the groups. Secondary outcome were change in spirometry values within groups, and difference between the groups. A total of 140 children participated. The groups did not differ in age, sex, mother tongue, or weight. Nor in mean FVC (MC 89.2% ± 16.7, control 89.5% ± 16.3) mean FEV1 (MC 91.3% ± 15.6, control 94.2% ± 16.8), and expiratory time (MC 1.58 ± 0.43, control 1.7 ± 0.44) in first spirometry. In second spirometry the control group had a similar FVC, FEV1, and expiratory time. The MC group had a significant improvement in all parameters: FVC: MC 95.3% ± 15.5, control 89.3% ± 19.1, FEV1: MC 98.0% ± 15.6, control 91.8% ± 19.3, and expiratory time MC 1.96 ± 0.55, control 1.84 ± 0.52. The differences between the groups between first and second attempt were significant (P-value FVC 0.000, FEV1 0.000, expiratory time 0.003). MCs improved performance of spirometry among preschoolers. It is possible that laughter and relief of stress had a physiological effect. Further studies are required to better establish the ability of MCs to improve active participation and to better understand whether the mechanism of the improvement is better cooperation or true physiological change. © 2018 Wiley Periodicals, Inc.

In this review, the most important complementary und alternative therapies are discussed, focusing particularly on their use in otorhinolaryngology. These therapies include balneology, Kneipp therapy, microbiological therapy, fasting, excretion therapy, different oxygen therapies, hydro-colon therapy, urine therapy, own-blood therapy, Bach therapy, orthomolecular therapy, order therapy, environmental medicine, phytotherapy, homeopathy, complex homeopathy, anthroposophy, neural therapy, electroaccupuncture according to Voll and similar therapies, nasal reflex therapy, reflex-zone massage, manual therapy, massage, lymph drainage, aroma therapy, thermotherapy, bioresonance, kinesiology, hopi candles, and dietetics. Some of these methods and regimens can be recommended, but others should be rejected. In universities, these methods are only represented to a minor extend, but are more accepted by otorhinolaryngologists in practice. This paper provides a guide to which alternative therapies are sensible and possible in otorhinolaryngology. The aim is to stimulate interest in these methods. It is necessary to discuss these alternative methods reasonably and credibly with patients.

Personal therapy for undergraduate music therapy students: a survey of AMTA program coordinators.

PubMed

Gardstrom, Susan C; Jackson, Nancy A

2011-01-01

The primary purpose of this study was to gather information in order to understand if and how various modalities of personal therapy are employed with undergraduate music therapy students in the United States. AMTA degree program coordinators were asked about 3 therapy modalities, in particular: verbal therapy, music therapy, and expressive arts therapy (excluding music therapy). It was predicted that less than a quarter of the respondents would indicate that personal therapy of any modality was required in their undergraduate curricula, but that a larger percentage would indicate that it was encouraged. Both hypotheses were supported, with just over 14% of the respondents indicating that they require some form of personal therapy and 32% indicating that they encourage it, with 73% of this latter subgroup encouraging verbal therapy and 46% encouraging music therapy. It was further predicted that, when therapy was required or encouraged, it was most often provided by an individual who was associated with the college/university and that therapy was usually provided in a group format. Respondent comments related to these 2 questions revealed considerable confusion between experiential exercises and personal therapy, leading to dubious validity of some of the numerical data. Qualitative treatment of narrative responses illuminated 4 salient issues regarding personal therapy for undergraduate music therapy students, as follows: (a) the legal and ethical feasibility of making personal therapy a requirement; (b) the cost and availability of qualified professionals; (c) the benefits of personal therapy as an integral facet of undergraduate music therapy training and education; and (d) the appropriateness of personal therapy at the undergraduate level of training.

The Incremental Effects of Manual Therapy or Booster Sessions in Addition to Exercise Therapy for Knee Osteoarthritis: A Randomized Clinical Trial.

2015-12-01

A factorial randomized controlled trial. To investigate the addition of manual therapy to exercise therapy for the reduction of pain and increase of physical function in people with knee osteoarthritis (OA), and whether "booster sessions" compared to consecutive sessions may improve outcomes. The benefits of providing manual therapy in addition to exercise therapy, or of distributing treatment sessions over time using periodic booster sessions, in people with knee OA are not well established. All participants had knee OA and were provided 12 sessions of multimodal exercise therapy supervised by a physical therapist. Participants were randomly allocated to 1 of 4 groups: exercise therapy in consecutive sessions, exercise therapy distributed over a year using booster sessions, exercise therapy plus manual therapy without booster sessions, and exercise therapy plus manual therapy with booster sessions. The primary outcome measure was the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC score; 0-240 scale) at 1-year follow-up. Secondary outcome measures were the numeric pain-rating scale and physical performance tests. Of 75 participants recruited, 66 (88%) were retained at 1-year follow-up. Factorial analysis of covariance of the main effects showed significant benefit from booster sessions (P = .009) and manual therapy (P = .023) over exercise therapy alone. Group analysis showed that exercise therapy with booster sessions (WOMAC score, -46.0 points; 95% confidence interval [CI]: -80.0, -12.0) and exercise therapy plus manual therapy (WOMAC score, -37.5 points; 95% CI: -69.7, -5.5) had superior effects compared with exercise therapy alone. The combined strategy of exercise therapy plus manual therapy with booster sessions was not superior to exercise therapy alone. Distributing 12 sessions of exercise therapy over a year in the form of booster sessions was more effective than providing 12 consecutive exercise therapy sessions. Providing manual therapy in addition to exercise therapy improved treatment effectiveness compared to providing 12 consecutive exercise therapy sessions alone.

2016-01-01

AIM: To evaluate the applicability of nonbismuth concomitant quadruple therapy for Helicobacter pylori (H. pylori) eradication in Chinese regions. METHODS: A systematic review and meta-analysis of randomized controlled trials was performed to evaluate the efficacy of nonbismuth concomitant quadruple therapy between sequential therapy or triple therapy for H. pylori eradication in Chinese regions. The defined Chinese regions include China, Hong Kong, Taiwan, and Singapore. The primary outcome was the H. pylori eradication rate; the secondary outcome was the compliance with therapy. The PubMed, Embase, Scopus, and Cochrane databases were searched for studies published in the period up to March 2016 with no language restriction. RESULTS: We reviewed six randomized controlled trials and 1616 patients. In 3 trials comparing concomitant quadruple therapy with triple therapy, the H. pylori eradication rate was significantly higher for 7-d nonbismuth concomitant quadruple therapy than for 7-d triple therapy (91.2% vs 77.9%, risk ratio = 1.17, 95%CI: 1.09-1.25). In 3 trials comparing quadruple therapy with sequential therapy, the eradication rate was not significant between groups (86.9% vs 86.0%). However, higher compliance was achieved with concomitant therapy than with sequential therapy. CONCLUSION: The H. pylori eradication rate was higher for nonbismuth concomitant quadruple therapy than for triple therapy. Moreover, higher compliance was achieved with nonbismuth concomitant quadruple therapy than with sequential therapy. Thus, nonbismuth concomitant quadruple therapy should be the first-line treatment in Chinese regions. PMID:27340362

Can we predict failure in couple therapy early enough to enhance outcome?

PubMed

Pepping, Christopher A; Halford, W Kim; Doss, Brian D

2015-02-01

Feedback to therapists based on systematic monitoring of individual therapy progress reliably enhances therapy outcome. An implicit assumption of therapy progress feedback is that clients unlikely to benefit from therapy can be detected early enough in the course of therapy for corrective action to be taken. To explore the possibility of using feedback of therapy progress to enhance couple therapy outcome, the current study tested whether weekly therapy progress could detect off-track clients early in couple therapy. In an effectiveness trial of couple therapy, 136 couples were monitored weekly on relationship satisfaction and an expert derived algorithm was used to attempt to predict eventual therapy outcome. As expected, the algorithm detected a significant proportion of couples who did not benefit from couple therapy at Session 3, but prediction was substantially improved at Session 4 so that eventual outcome was accurately predicted for 70% of couples, with little improvement of prediction thereafter. More sophisticated algorithms might enhance prediction accuracy, and a trial of the effects of therapy progress feedback on couple therapy outcome is needed. Copyright © 2015 Elsevier Ltd.

A wide array of new forms and combinations of play therapy have been developed. The aim of the second part of this paper is to present an overview of these newer approaches, including: focussed therapies for specific disorders; behavioural approaches like the Cognitive-Behavioral Play Therapy and the Parent-Child Interaction Therapy; various combinations with family therapy; and therapies especially for preschool children like Filial Therapy, Developmental Play Therapy and Thera-play. Following a phase of experiments and combinations, the empirical evaluation of many play-therapy forms is needed. Especially questions of the differential indication of specific play-therapies and their effectiveness in the therapeutical practice need to be studied.

Patients have to discontinue the use of oral iron therapy due to the development of side effects and lack of long-term adherence to medication for iron deficiency anemia. This study aimed to evaluate the therapeutic effectiveness, safety, and cost of intravenous iron sucrose therapy. The computerized database and medical records of 453 patients diagnosed with iron deficiency anemia who received intravenous iron sucrose therapy for iron deficiency anemia between 2004 and 2008 were reviewed. The improvement of hematologic parameters and cost of therapy were evaluated 4 weeks after therapy. 453 patients (443 females, 10 males; age: 44.2 +/- 12.3 years) received iron sucrose therapy. Mean hemoglobin, hematocrit, and mean corpuscular volume values were 8.2 +/- 1.4 g/dL, 26.9 +/- 3.8%, and 66.1 +/- 7.8 fL, respectively, before therapy and 11.5 +/- 1.0 g/dL, 35.8 +/- 2.5%, 76.5 +/- 6.1 fL, respectively, after therapy (P < 0.001). A mean ferritin level of 3.4 +/- 2.4 ng/mL before therapy increased to 65.9 +/- 40.6 ng/mL after therapy (P < 0.001). All patients responded to intravenous iron therapy (transferrin saturation values of the patients were >50%). The mean cost of therapy was 143.07 +/- 29.13 US dollars. The therapy was well tolerated. Although the cost of intravenous iron sucrose therapy may seem high, a lack of adherence to therapy and side effects including gastrointestinal irritation during oral iron therapy were not experienced during intravenous therapy.

Art therapy, psychodrama, and verbal therapy. An integrative model of group therapy in the treatment of adolescents with anorexia nervosa and bulimia nervosa.

Anorexia nervosa and bulimia nervosa typically afflict individuals in adolescence. Given the intractability of these diseases in combination with the natural recalcitrance of adolescence, treatment with this population presents a daunting challenge. Traditional group therapy that focuses on verbal therapy is often not effective with this population, particularly in the acute stages of the diseases. A group therapy approach that integrates art therapy, psychodrama, and verbal therapy offers an innovative alternative to traditional group therapy.

The primary aim was to investigate the comparative effects of massage therapy and exercise therapy on patients with multiple sclerosis. The secondary aim was to investigate whether combination of both massage and exercise has an additive effect. Randomized controlled pilot trial with repeated measurements and blinded assessments. Local Multiple Sclerosis Society. A total of 48 patients with multiple sclerosis were randomly assigned to four equal subgroups labelled as massage therapy, exercise therapy, combined massage-exercise therapy and control group. The treatment group received 15 sessions of supervised intervention for five weeks. The massage therapy group received a standard Swedish massage. The exercise therapy group was given a combined set of strength, stretch, endurance and balance exercises. Patients in the massage-exercise therapy received a combined set of massage and exercise treatments. Patients in the control group were asked to continue their standard medical care. Pain, fatigue, spasticity, balance, gait and quality of life were assessed before and after intervention. Massage therapy resulted in significantly larger improvement in pain reduction (mean change 2.75 points, P = 0.001), dynamic balance (mean change, 3.69 seconds, P = 0.009) and walking speed (mean change, 7.84 seconds, P = 0.007) than exercise therapy. Patients involved in the combined massage-exercise therapy showed significantly larger improvement in pain reduction than those in the exercise therapy (mean change, 1.67 points, P = 0.001). Massage therapy could be more effective than exercise therapy. Moreover, the combination of massage and exercise therapy may be a little more effective than exercise therapy alone.

Ultimately, the outcome of therapy is to enable the PWA to…

Empirically-supported and non-empirically supported therapies for bulimia nervosa: retrospective patient ratings

PubMed Central

2013-01-01

Background Empirically supported therapies for bulimia nervosa include cognitive behaviour therapy and interpersonal therapy. Whilst these treatments have been shown to be effective in multiple randomised controlled trials, little research has investigated how they are perceived by patients who receive them. This study investigated whether empirically-supported psychological therapies (ESTs) are associated with superior self-rated treatment outcomes in clients with Bulimia Nervosa (BN). Results 98 adults who had received psychological therapy for BN in the United Kingdom completed a questionnaire which retrospectively assessed the specific contents of their psychological therapy and self-rated treatment outcomes. Around half the sample, fifty three participants reported receiving an EST. Fifty of these received Cognitive Behaviour Therapy (CBT) and three Interpersonal Therapy (IPT). Where therapy met expert criteria for Cognitive Behaviour Therapy for Bulimia Nervosa (CBT-BN, an EST) participants reported superior treatment outcomes than those who appeared to receive non-specialist cognitive-behavioural therapy. However, self-rated treatment outcomes were similar overall between those whose therapy met criteria for ESTs and those whose therapy did not. Conclusions The findings offer tentative support for the perceived helpfulness of CBT-BN as evaluated in controlled research trials. Cognitive-behavioural therapies for BN, as they are delivered in the UK, may not necessarily be perceived as more beneficial by clients with BN than psychological therapies which currently have less empirical support.

Gene therapy is divided into somatic and germ line therapy. The latter involves reproductive cells or their stem cells, and its results are heritable. The effects of somatic gene therapy are generally restricted to a single tissue of the patient in question. Until now, all gene therapies in the world have belonged to the regime of somatic therapy, germ line therapy having been a theoretical possibility only. Very recently, however, a method has been developed which is applicable to germ line therapy as well. In addition to technical challenges, severe ethical problems are associated with germ line therapy, demanding opinion statement.

Design Prospective observational cohort. Setting Inpatient rehabilitation. Participants 2,130 consecutive admissions for initial TBI rehabilitation at 10 inpatient rehabilitation facilities (9 in US and 1 Canada) from October 2008 to September 2011. Interventions n/a Main Outcome Measure(s) proportion of sessions that were group therapy (two or more patients were treated simultaneously by one or more clinicians); proportion of patients receiving group therapy; type of activity performed and amount of time spent in group therapy, by discipline; rehabilitation length of stay (RLOS); discharge location; FIM Cognitive and Motor scores at discharge. Results 79% of patients received at least 1 session of group therapy, with group therapy accounting for 13.7% of all therapy sessions and 15.8% of therapy hours. On average, patients spent 2.9 hours per week in group therapy. The greatest proportion of treatment time in group format was in Therapeutic Recreation (25.6%), followed by Speech Therapy (16.2%), Occupational Therapy (10.4%), Psychology (8.1%), and Physical Therapy (7.9%). Group therapy time and type of treatment activities varied among admission FIM cognitive subgroups and treatment sites. Several factors appear to be predictive of receiving group therapy, with treatment site being a major influence. However, group therapy as a whole offered little explanation of differences in the outcomes studied. Conclusion(s) Group therapy is commonly used in TBI rehabilitation, to varying degrees among disciplines, sites, and cognitive impairment subgroups. Various therapeutic activities take place in group therapy, indicating its perceived value in addressing many domains of functioning. Variation in outcomes is not explained well by overall percent of therapy time delivered in groups. PMID:26212404

Intra-articular therapies for osteoarthritis.

PubMed

Yu, Shirley P; Hunter, David J

2016-10-01

Conventional medical therapies for osteoarthritis are mainly palliative in nature, aiming to control pain and symptoms. Traditional intra-articular therapies are not recommended in guidelines as first line therapy, but are potential alternatives, when conventional therapies have failed. Current and future intra-articular drug therapies for osteoarthritis are highlighted, including corticosteroids, hyaluronate, and more controversial treatments marketed commercially, namely platelet rich plasma and mesenchymal cell therapy. Intraarticular disease modifying osteoarthritis drugs are the future of osteoarthritis treatments, aiming at structural modification and altering the disease progression. Interleukin-1β inhibitor, bone morphogenic protein-7, fibroblast growth factor 18, bradykinin B2 receptor antagonist, human serum albumin, and gene therapy are discussed in this review. The evolution of drug development in osteoarthritis is limited by the ability to demonstrate effect. High quality trials are required to justify the use of existing intra-articular therapies and to advocate for newer, promising therapies. Challenges in osteoarthritis therapy research are fundamentally related to the complexity of the pathological mechanisms of osteoarthritis. Novel drugs offer hope in a disease with limited medical therapy options. Whether these future intra-articular therapies will provide clinically meaningful benefits, remains unknown.

A history of music therapy journal articles published in the English language.

2003-01-01

Music therapists have had an interest in bibliographic research for over 20 years, beginning with Jellison's 1973 analysis of the frequency and types of articles appearing in the existing music therapy literature. Since then, several other researchers have continued in this line of inquiry. The purpose of this study was to (a) identify historical trends in the types of articles that have been published in major music therapy periodicals in the English language, (b) identify historical trends for each type of article within each music therapy journal, (c) to compare percentages of article types within each music therapy journal and (d) to compare percentages of article types across journals. Specifically, how many quantitative, qualitative, historical, philosophical/theoretical, clinical and professional articles have been published throughout the history of the following journals: Journal of Music Therapy, Music Therapy: Journal of the American Association for Music Therapy, Music Therapy Perspectives, The Arts in Psychotherapy, Journal of the Association for Music & Imagery, The Australian Journal of Music Therapy, The Nordic Journal of Music Therapy, The British Journal of Music Therapy, and The New Zealand Society for Music Therapy Journal.

The number of studies evaluating the efficacy and safety of third-line molecular-targeted therapy for metastatic renal cell carcinoma (mRCC) is limited. The data for 48 patients with disease progression after first-line vascular endothelial growth factor receptor tyrosine kinase inhibitor (TKI) and second-line targeted therapy were evaluated. Patients with prior cytokine therapy were excluded. Overall survival (OS) after first- and second-line therapy initiation was compared between patients with and without third-line therapy. In addition, dose-limiting toxicities (DLTs) were evaluated. Twenty-two of 48 patients (45.8%) received third-line therapy, and TKI and mammalian target of rapamycin inhibitor were each administered in 11 patients (50%). Patients with third-line therapy had significantly longer median OS after first-line therapy (26.6 vs. 14.6 months, p = 0.0010) and second-line therapy (18.2 vs. 7.4 months, p < 0.0001) compared to those without third-line therapy. Multivariate analysis showed that the use of third-line therapy following second-line therapy was an independent prognosticator for longer OS (hazard ratio 0.29, 95% confidence interval 0.14-0.58, p = 0.0005). The median progression-free survival and OS after third-line therapy was 2.76 and 8.71 months, respectively. Although a high frequency of DLTs was observed (n = 10, 45.5%), the frequencies were similar among the sequential therapies. Third-line therapy has a beneficial therapeutic effect in patients with mRCC that is resistant to previous therapies. However, there is a need to evaluate in detail the high frequency of adverse events, including DLTs.

Music therapy is increasingly used to help heal patients. However, there is a significant gap in the literature about nurses' attitudes toward and need for education in music therapy for nursing practice. This cross-sectional study was conducted to describe nurses' attitudes toward music therapy and determine their need for education in music therapy. Participants included 1,197 nurses who were recruited from hospitals in different regions of Taiwan. Participants expressed positive attitudes toward music therapy. Most participants were willing to learn about music therapy. "Skill in using musical instruments" was the most frequently identified educational need. Further study of the discrepancy between the attitudes toward "performing music therapy" and "learning music therapy" is needed to clarify why nurses expected that they would receive no support for attending music therapy education. Given participants' attitudes toward music therapy and their motivation for learning, nursing administrators and educators may consider developing policies to further the advancement of music therapy in educational programs and practice.

Objective Psychological treatments for posttraumatic stress disorder (PTSD) are usually delivered once or twice weekly over several months. It is unclear whether they can be successfully delivered over a shorter period of time. This clinical trial had two goals, (1) to investigate the acceptability and efficacy of a 7-day intensive version of cognitive therapy for PTSD, and (2) to investigate whether cognitive therapy has specific treatment effects by comparing intensive and standard weekly cognitive therapy with an equally credible alternative treatment. Method Patients with chronic PTSD (N=121) were randomly allocated to 7-day intensive or standard 3-month weekly cognitive therapy for PTSD, 3-month weekly emotion-focused supportive therapy, or a 14-week waitlist condition. Primary outcomes were PTSD symptoms and diagnosis as assessed by independent assessors and self-report. Secondary outcomes were disability, anxiety, depression, and quality of life. Measures were taken at initial assessment, 6 weeks and 14 weeks (post-treatment/wait). For groups receiving treatment, measures were also taken at 3 weeks, and follow-ups at 27 and 40 weeks after randomization. All analyses were intent-to-treat. Results At post-treatment/wait assessment, 73%, 77%, 43%, 7% of the intensive cognitive therapy, standard cognitive therapy, supportive therapy, and waitlist groups, respectively, had recovered from PTSD. All treatments were well tolerated and were superior to waitlist on all outcome measures, with the exception of no difference between supportive therapy and waitlist on quality of life. For primary outcomes, disability and general anxiety, intensive and standard cognitive therapy were superior to supportive therapy. Intensive cognitive therapy achieved faster symptom reduction and comparable overall outcomes to standard cognitive therapy. Conclusions Cognitive therapy for PTSD delivered intensively over little more than a week is as effective as cognitive therapy delivered over 3 months. Both had specific effects and were superior to supportive therapy. Intensive cognitive therapy for PTSD is a feasible and promising alternative to traditional weekly treatment. PMID:24480899

Does prior psychotherapy experience affect the course of cognitive-behavioural group therapy for social anxiety disorder?

PubMed

Delsignore, Aba

2008-08-01

To examine whether and how different patterns of psychotherapy history (no prior therapy, successful therapy experience, and unsuccessful therapy experience) affect the outcome of future treatment among patients undergoing cognitive-behavioural group therapy for social anxiety disorder. Fifty-seven patients with varying histories of psychotherapy participating in cognitive-behavioural group treatment for social anxiety disorder were included in the study. Symptom severity (including anxiety, depression, self-efficacy, and global symptom severity) was assessed at pre- and posttreatment. A therapist-rated measure of patient therapy engagement was included as a process variable. First-time therapy patients showed more favourable pretreatment variables and achieved greater benefit from group therapy. Among patients with unsuccessful therapy experience, substantial gains were attained by those who were able to actively engage in the therapy process. Patients rating previous therapies as successful could benefit the least and tended to stagnate. Possible explanations for group differences and clinical implications are discussed. Prior psychotherapy experience affects the course of cognitive-behavioural group therapy in patients with social phobias. While patients with negative therapy experience may need extensive support in being and remaining actively engaged, those rating previous therapies as successful should be assessed very carefully and may benefit from a major focus on relational aspects.

[Conservative therapy of cartilage defects of the upper ankle joint].

PubMed

Smolenski, U C; Best, N; Bocker, B

2008-03-01

Cartilage defects of the upper ankle joint reflect the problem that great force is transmitted and balanced out over a relatively small surface area. As a pathophysiological factor, cartilage-bone contusions play a significant role in the development of cartilage defects of the upper ankle joint. Physiotherapeutic procedures belong to the standard procedures of conservative therapy. The use and selection of the type of therapy is based on empirical considerations and experience and investigations on effectiveness of particular therapies are relatively rare. At present a symptom-oriented therapy of cartilage defects of the upper ankle joint seems to be the most sensible approach. It can be assumed that it makes sense that the symptomatic treatment of cartilage defects or initial stages of arthritis also includes the subsequent symptoms of pain, irritated condition and limited function. This leads to starting points for physiotherapy with respect to pain therapy, optimisation of pressure relationships, avoidance of pressure points, improvement of diffusion and pressure release. In addition to the differential physiotherapeutic findings, the determination of a curative, preventive or rehabilitative procedure is especially important. In physical therapy special importance is placed on a scheduled serial application corresponding to the findings, employing the necessary methods, such as physiotherapy, sport therapy, medical mechanics, manual therapy, massage, electrotherapy and warmth therapy. From this the findings-related therapy is proposed as a practical therapy concept: locomotive apparatus pain therapy, optimisation of pressure relationships, improvement of diffusion and decongestion therapy. Therapy options have been selected base on the current literature and are summarised in tabular form. The art of symptomatic therapy of cartilage defects of the upper ankle joint does not lie in the multitude of sometimes speculative procedures, but in the targeted selection of a therapy regime based on the therapeutic goal, a corresponding application dose and serial design.

Cognitive impairment after critical illness is common and debilitating. We developed a cognitive therapy program for critically ill patients and assessed the feasibility and safety of administering combined cognitive and physical therapy early during a critical illness. We randomized 87 medical and surgical ICU patients with respiratory failure and/or shock in a 1:1:2 manner to three groups: usual care, early once-daily physical therapy, or early once-daily physical therapy plus a novel, progressive, twice-daily cognitive therapy protocol. Cognitive therapy included orientation, memory, attention, and problem-solving exercises, and other activities. We assessed feasibility outcomes of the early cognitive plus physical therapy intervention. At 3 months, we also assessed cognitive, functional, and health-related quality of life outcomes. Data are presented as median (interquartile range) or frequency (%). Early cognitive therapy was a delivered to 41/43 (95%) of cognitive plus physical therapy patients on 100% (92-100%) of study days beginning 1.0 (1.0-1.0) day following enrollment. Physical therapy was received by 17/22 (77%) of usual care patients, by 21/22 (95%) of physical therapy only patients, and 42/43 (98%) of cognitive plus physical therapy patients on 17% (10-26%), 67% (46-87%), and 75% (59-88%) of study days, respectively. Cognitive, functional, and health-related quality of life outcomes did not differ between groups at 3-month follow-up. This pilot study demonstrates that early rehabilitation can be extended beyond physical therapy to include cognitive therapy. Future work to determine optimal patient selection, intensity of treatment, and benefits of cognitive therapy in the critically ill is needed.

Data on inappropriate implantable cardioverter-defibrillator (ICD) therapy and effects of programming by heart rate are lacking. We aimed to characterize inappropriate ICD therapy and assess the effects of novel programming by heart rate. Incidence and causes of inappropriate therapy by heart rate range (below or above 200 bpm) were assessed. Predictors of inappropriate therapy and effects of programming by heart rate were evaluated with multivariate Cox regression models. Crossovers were excluded. Inappropriate therapy occurred in 9.2% of the total patient population, with 19% of patients randomized to study arm A, 3.6% in arm B, and 4.7% in arm C. Inappropriate therapies <200 bpm were attributable to supraventricular tachycardia (SVT)/sinus tachycardia (78%) or atrial fibrillation/flutter (20%). Inappropriate therapy ≥200 bpm occurred because of SVT (47%), atrial fibrillation/flutter (41%), or electromagnetic interference (13%). Conventional ICD programming was associated with more inappropriate therapy <200 bpm than high-rate or delayed therapy, as were younger age, history of atrial arrhythmia, advanced New York Heart Association functional class, ICD versus cardiac resynchronization therapy with defibrillator, and absence of diabetes. High-rate and long-delay therapy significantly reduced the risk of inappropriate therapy in the <200 bpm range. Long delay was associated with further reduction of fast (≥200 bpm) inappropriate therapy (P = .032) and a reduction in subsequent inappropriate episodes (P = .006). In MADIT-RIT, inappropriate ICD therapy is most frequent at rates below 200 bpm and can be predicted, and effectively prevented, with high-rate cutoff programming. Long-delay therapy effectively reduces fast inappropriate therapy ≥200 bpm and subsequent events. [ http://clinicaltrials.gov/ct2/show/NCT00947310]. Copyright © 2015 Heart Rhythm Society.

Background: Occupational therapy is an important co-therapy in psychiatric therapy. It is a common belief that no risks are associated with occupational therapy. Negative effects caused by group therapy, especially occupational therapy, have not been in the focus of research yet. In this study we want to illustrate possible types and intensities of group side effects through occupational therapy. Patients and Methods: Patients of an inpatient rehabilitation facility filled out the Adverse Treatment Reaction Group Checklist. The checklist contains 47 items divided in six dimensions: group size, content, group participants, group outcome and global. The self-rating used a 5-point likert scale (0 = not at all; 4 = very much, extremely stressful) and gives information about types and intensities of the side effects. Results: 88.9 % of 45 patients reported negative effects of occupational group therapy. 28.9 % of the patients rated the side effect as at least severe. Discussion: Occupational therapy is associated with side effects as every other group therapy. Possible side effects caused by group therapy should be considered while planning and implementing occupational therapy. © Georg Thieme Verlag KG Stuttgart · New York.

Carbon nanotubes (CNTs) have shown great potential in both photothermal therapy and drug delivery. In this study, a CNT derivative, hyaluronic acid-derivatized CNTs (HA-CNTs) with high aqueous solubility, neutral pH, and tumor-targeting activity, were synthesized and characterized, and then a new photodynamic therapy agent, hematoporphyrin monomethyl ether (HMME), was adsorbed onto the functionalized CNTs to develop HMME-HA-CNTs. Tumor growth inhibition was investigated both in vivo and in vitro by a combination of photothermal therapy and photodynamic therapy using HMME-HA-CNTs. The ability of HMME-HA-CNT nanoparticles to combine local specific photodynamic therapy with external near-infrared photothermal therapy significantly improved the therapeutic efficacy of cancer treatment. Compared with photodynamic therapy or photothermal therapy alone, the combined treatment demonstrated a synergistic effect, resulting in higher therapeutic efficacy without obvious toxic effects to normal organs. Overall, it was demonstrated that HMME-HA-CNTs could be successfully applied to photodynamic therapy and photothermal therapy simultaneously in future tumor therapy. PMID:23843694

The use of manual therapies (chiropractic manipulation, massage) and movement therapies (yoga, tai chi) by people with arthritis may relate to their personal characteristics, and the reported emotional and physical health outcomes may differ by type of therapy. To describe personal characteristics and predictors of manual and movement therapy use for people with arthritis, and to compare the use of manual versus movement therapy to improve physical and emotional health outcomes for people with arthritis. CAM respondents with arthritis were identified from the 2012 National Health Interview Survey (n = 8229). Data were analyzed to determine the overall percentages of CAM users, and to examine the associations between use/nonuse using multivariable linear regressions. White, well-educated, physically active females were more likely to use both types of therapy. Movement therapy users reported positive emotional health outcomes twice as much as manual therapy users and 10% more reported positive physical health outcomes. While both movement and manual therapies can have positive effects on people with arthritis, it appears that active therapies are more beneficial than passive therapies.

From hypertension to diabetes, cancer to HIV, stroke to memory loss and learning disorders to septic shock, male impotence to tuberculosis, there is probably no pathological condition where nitric oxide does not play an important role. Nitric oxide is an analgesic, immune-modulator, vasodilator, anti-apoptotic, growth modulator, angiogenetic, anti-thrombotic, anti-inflammatory and neuro-modulator. Because of the above actions of nitric oxide, many clinical conditions associated with abnormal Nitric oxide (NO) production and bioavailability. Our novel therapeutic approach is to restore the homeostasis of nitric oxide and replace the lost cells by combining nitric oxide therapy, anti-oxidative therapy, low level laser therapy, plasma rich platelet therapy and stem cell therapy.

2015-06-01

The rejection of an application for ambulant geriatric rehabilitation (AGRV) is usually justified by the argument that non-pharmaceutical therapy prescribed by doctors accredited by social housing institutions (SHI) would suffice. The reality in healthcare during the 6 months following an application is unknown. In this study 203 patients who had made an application for AGRV in the second half of 2010 in Flensburg, Lübeck or Ratzeburg were interviewed by telephone. The survey revealed that 25.7% of the applications for AGRV had been rejected. The majority of these patients received no ambulant non-pharmaceutical therapy (e.g. physical therapy, physiotherapy, occupational therapy, speech therapy or psychological therapy), less than 20% received more than 12 therapy sessions and in most cases exclusively physiotherapy. The 141 successful AGRV applicants received additional ambulant therapies of a similar magnitude. The difference between the intensified interdisciplinary therapy offered in the AGRV and additionally and the offer to rejected applicants is substantial.

Cell therapy has been shown to be a key clinical therapeutic option for central nervous system diseases or damage. Standardization of clinical cell therapy procedures is an important task for professional associations devoted to cell therapy. The Chinese Branch of the International Association of Neurorestoratology (IANR) completed the first set of guidelines governing the clinical application of neurorestoration in 2011. The IANR and the Chinese Association of Neurorestoratology (CANR) collaborated to propose the current version “Clinical Cell Therapy Guidelines for Neurorestoration (IANR/CANR 2017)”. The IANR council board members and CANR committee members approved this proposal on September 1, 2016, and recommend it to clinical practitioners of cellular therapy. These guidelines include items of cell type nomenclature, cell quality control, minimal suggested cell doses, patient-informed consent, indications for undergoing cell therapy, contraindications for undergoing cell therapy, documentation of procedure and therapy, safety evaluation, efficacy evaluation, policy of repeated treatments, do not charge patients for unproven therapies, basic principles of cell therapy, and publishing responsibility.

Variation in the Use of Therapy following Distal Radius Fractures in the United States

PubMed Central

Waljee, Jennifer F.; Zhong, Lin; Shauver, Melissa

2014-01-01

Background: Distal radius fractures (DRFs) are one of the most common injuries among the elderly, resulting in significant expense and disability. The specific aims of this study are (1) to examine rates of therapy following DRFs and (2) to identify those factors that influence utilization of therapy and time span between DRF treatment and therapy among a national cohort of elderly patients. Methods: We examined national use of physical and occupational therapy among all Medicare beneficiaries who suffered DRFs between January 1, 2007, and October 1, 2007, and assessed the effect of treatment, patient-related, and surgeon-related factors on utilization of therapy. Results: Overall, 20.6% of patients received either physical or occupational therapy following DRF. Use of therapy varied by DRF treatment, and patients who underwent open reduction and internal fixation were more likely to receive therapy compared with patients who received closed reduction. Patients who received open reduction and internal fixation were also referred to therapy earlier compared with patients who received external fixation, percutaneous pinning, and closed reduction. Surgeon specialization is associated with greater use of postoperative therapy. Patient predictors of therapy use include younger age, female sex, higher socioeconomic status, and fewer comorbidity conditions. Conclusion: Use of therapy following DRF varies significantly by both patient- and surgeon-related factors. Identifying patients who benefit from postinjury therapy can allow for better resource utilization following these common injuries. PMID:25289323

To determine the effectiveness of a manual therapy program compared with an exercise therapy program in patients with osteoarthritis (OA) of the hip. A single-blind, randomized clinical trial of 109 hip OA patients was carried out in the outpatient clinic for physical therapy of a large hospital. The manual therapy program focused on specific manipulations and mobilization of the hip joint. The exercise therapy program focused on active exercises to improve muscle function and joint motion. The treatment period was 5 weeks (9 sessions). The primary outcome was general perceived improvement after treatment. Secondary outcomes included pain, hip function, walking speed, range of motion, and quality of life. Of 109 patients included in the study, 56 were allocated to manual therapy and 53 to exercise therapy. No major differences were found on baseline characteristics between groups. Success rates (primary outcome) after 5 weeks were 81% in the manual therapy group and 50% in the exercise group (odds ratio 1.92, 95% confidence interval 1.30, 2.60). Furthermore, patients in the manual therapy group had significantly better outcomes on pain, stiffness, hip function, and range of motion. Effects of manual therapy on the improvement of pain, hip function, and range of motion endured after 29 weeks. The effect of the manual therapy program on hip function is superior to the exercise therapy program in patients with OA of the hip.

2018-05-01

Acute course of electroconvulsive therapy is effective in inducing remission from depression, but recurrence rate is unacceptably high following termination of electroconvulsive therapy despite continued pharmacotherapy. Continuation electroconvulsive therapy and maintenance electroconvulsive therapy have been studied for their efficacy in preventing relapse and recurrence of depression. The purpose of this meta-analysis was to examine the efficacy of continuation electroconvulsive therapy and maintenance electroconvulsive therapy in preventing relapse and recurrence of depression in comparison to antidepressant pharmacotherapy alone. We searched MEDLINE, Embase, PsycINFO, clinicaltrials.gov and Cochrane register of controlled trials from the database inception to December 2016 without restriction on language or publication status for randomized trials of continuation electroconvulsive therapy and maintenance electroconvulsive therapy. Two independent Cochrane reviewers extracted the data in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines for systematic reviews and meta-analyses. The risk of bias was assessed using four domains of the Cochrane Collaboration Risk of Bias Tool. Outcomes were pooled using random effect model. The primary outcome was relapse or recurrence of depression. Five studies involving 436 patients were included in the meta-analysis. Analysis of the pooled data showed that continuation electroconvulsive therapy and maintenance electroconvulsive therapy, both with pharmacotherapy, were associated with significantly fewer relapses and recurrences than pharmacotherapy alone at 6 months and 1 year after a successful acute course of electroconvulsive therapy (risk ratio = 0.64, 95% confidence interval = [0.41, 0.98], p = 0.04, risk ratio = 0.46, 95% confidence interval = [0.21, 0.98], p = 0.05, respectively). There was insufficient data to perform a meta-analysis of stand-alone continuation electroconvulsive therapy or maintenance electroconvulsive therapy beyond 1 year. There are only a few randomized trials of continuation electroconvulsive therapy and maintenance electroconvulsive therapy. The preliminary and limited evidence suggests the modest efficacy of continuation electroconvulsive therapy and maintenance electroconvulsive therapy with concomitant pharmacotherapy in preventing relapse and recurrence of depressive episodes for 1 year after the remission of index episode with the acute course of electroconvulsive therapy.

There is limited data regarding the relationship between age and inappropriate therapy among patients with an implantable cardioverter-defibrillator (ICD) and resynchronization therapy. We aimed to investigate this relationship and the effect of ICD programming on inappropriate therapy by age. In the Multicenter Automatic Defibrillator Implantation Trial-Reduce Inappropriate Therapy (MADIT-RIT) 1500 patients were randomized to 3 ICD programming arms: (A) conventional with ventricular tachycardia (VT) therapy ≥170; (B) high-rate cutoff with VT therapy ≥200, and (C) prolonged 60-second delay for VT therapy ≥170. We investigated the relationship between age, the risk of inappropriate ICD therapy (including antitachycardia pacing [ATP] or shock), and ICD programming. Cumulative incidence function Kaplan-Meier graphs showed an inverse relationship between increasing quartiles of age (Q1: ≤55, Q2: 56-64, Q3: 65-71, and Q4: ≥72 years) and the risk for inappropriate therapy. Multivariate analyses showed that each increasing decade of life was associated with 34% (P < .001), 27% (P < .001), and 26% (P < .001) reduction in the risk of inappropriate shock, inappropriate ATP, and any inappropriate therapy, respectively. Treatment arms B and C as compared with arm A were associated with a significant reduction in the risk of inappropriate therapies across all age quartiles (P < .001 for all). Among patients with a primary prevention indication for an ICD, there is an inverse relationship between age and inappropriate ICD therapy. Innovative ICD programming of high-rate cutoff or prolonged delay for VT therapy is associated with significant reductions in inappropriate therapy among all age groups.

This study aims to investigate whether 2-week spa therapy, as an adjunct to usual pharmacological therapy, has any beneficial effect in patients with rheumatoid arthritis (RA). In this single-blind crossover study, 50 patients were randomly assigned in a 1:1 manner to receive usual pharmacological therapy plus 2-week spa therapy or usual pharmacological therapy alone (period 1.6 months); after a 9-month washout, patients were crossed over to the opposite assignment (period 2.6 months). Spa therapy program included a daily saline balneotherapy session at 36-37 °C for 20 min except Sundays. The clinical outcomes were evaluated at baseline, after spa therapy (2 weeks) and 3 and 6 months after the spa therapy in both period and were pain (Visual Analogue Scale (VAS)), patient and physician global assessments (VAS), Health Assessment Questionnaire (HAQ), and Disease Activity Score (DAS28). Spa therapy was superior to control therapy in improving all the assessed clinical outcomes at the end of the spa therapy. This superiority persisted significantly in physician global assessment ( p = 0.010) and with a trend in favor of spa group in patient global assessment ( p = 0.058), function ( p = 0.092), and disease activity ( p = 0.098) at 3 months. Statistically significant improvements were found in spa therapy compared to control in disease activity ( p = 0.006) and patient ( p = 0.020) and physician global ( p = 0.011) assessments, and a trend toward improvements in pain ( p = 0.069) and swollen joints ( p = 0.070) at 6 months. A 2-week spa therapy adjunct to usual pharmacological therapy provided beneficial clinical effects compared to usual pharmacological therapy alone, in RA patients treated with traditional disease-modifying antirheumatic drugs. These beneficial effects may last for 6 months.

Perspectives of medical oncologists regarding music therapy for patients with cancer in Turkey - can musicology be integrated into psycho-oncology?

Music therapy is a common complementary and alternative therapy in addition to medical treatment for patients with cancer. If music therapy, which is known has a positive effect on human emotions and behaviors, is a useful additional therapy, it should be more integrated into pyscho-oncology. In this study, we aimed to determine medical oncologist attitudes to music therapy for patients with cancer and knowledge about musicology and music therapy in Turkey. This survey study included questions about participant attitudes and knowledge regarding music therapy as well as demographic characteristics. The population of the study were 402 physicians working in medical oncology in Turkey and the sample covered 112 participants in the the survey. For statistical analyses the chi-square test, Fischer exact test, and Mann-Whitney U analysis are applied. In our study the rate for medical oncologists who were interested in music therapy was 28% (n=112). Some 30% (n=34) of medical oncologists recommended music therapy for their patients and 55% (n=61) recommended music therapy to prevent anxiety in patients with cancer. In this study, for more harmony with patients and in order to ensure management of adverse effect, it was concluded that music therapy should be regrded as an additional therapy in oncology clinics.

Occupational therapy practitioners play an important role in improving the health of populations through the development of occupational therapy interventions at the population level and through advocacy to address occupational participation and the multiple determinants of health. This article defines and explores population health as a concept and describes the appropriateness of occupational therapy practice in population health. Support of population health practice as evidenced in the official documents of the American Occupational Therapy Association and the relevance of population health for occupational therapy as a profession are reviewed. Recommendations and directions for the future are included related to celebration of the achievements of occupational therapy practitioners in the area of population health, changes to the Occupational Therapy Practice Framework and educational accreditation standards, and the importance of supporting, recognizing, rewarding, and valuing occupational therapy practitioners who assume roles in which direct care is not their primary function.

Ethical issues in growth hormone therapy.

PubMed

Lantos, J; Siegler, M; Cuttler, L

1989-02-17

Pediatricians face clinical and ethical dilemmas about therapy to augment growth in short children who do not meet classic criteria for growth hormone (GH) deficiency. Biologic norms of health are unhelpful because of the uncertain relationship between stature, GH secretion, health, and disease. Instead, we suggest that GH therapy be evaluated from the perspective of cultural norms. We compare GH therapy for short normal children with currently accepted therapies for non--life-threatening pediatric conditions such as well-child care, cosmetic therapy, treatment of psychological problems, and invasive outpatient therapy for chronic conditions. Based on this analysis, we argue that the burdens of therapy, the uncertainty about long-term risks and benefits, the unclear therapeutic end point, and the implications for child health policy place routine GH therapy for children without documented deficiency of GH secretion outside current pediatric ethical norms. Such therapy is properly administered within a comprehensive clinical research protocol.

This summary provides an overview of how new therapies or new aspects of established therapies relate to the latest findings. Neoadjuvant therapy, local therapy, new aspects of systemic therapy, and prognostic and predictive factors are presented. In the neoadjuvant setting, the association between pathological complete response (pCR) and prognosis is still of interest as is the identification of new molecular predictors for new therapies such as CDK4/6 inhibitors. As regards surgical treatment, the target is still to reduce the aggressiveness of surgery. To achieve this, a better understanding particularly of ductal carcinoma in situ is required. With regard to systemic therapy, more data on the best combinations and therapy sequences for existing therapies is available. Finally, the use of prognostic and predictive factors may help to avoid overtreatment and ensure that patients only receive therapies which have been shown to be effective for their specific condition and have fewer side effects.

Predictors of change in music therapy with children and adolescents: the role of therapeutic techniques.

PubMed

Gold, Christian; Wigram, Tony; Voracek, Martin

2007-12-01

Music therapy has been shown to be efficacious in experimental studies. However, there is little empirical research knowledge about what elements of music therapy influence its effectiveness in clinical practice. Children and adolescents with psychopathology (N=75) were assessed before and after participating in individual music therapy with 1 out of 15 music therapists in the Vienna region. Relationships between outcomes (as evaluated by parents) and therapy contents (as reported by therapists) were examined using general linear modelling. Results indicated that clients' symptoms and burdens on their social environment showed greater improvement when music therapy was limited to discipline-specific music therapy techniques and did not include other media such as play therapy elements. The findings indicate the importance of being aware of a therapy method's specific strengths and limitations. More research on the indicated specific ingredients of music therapy intervention is needed.

Sarcomas comprise approximately one-third of canine intranasal tumors, however few veterinary studies have described survival times of dogs with histologic subtypes of sarcomas separately from other intranasal tumors. One objective of this study was to describe median survival times for dogs treated with radiation therapy for intranasal sarcomas. A second objective was to compare survival times for dogs treated with three radiation therapy protocols: daily-fractionated radiation therapy; Monday, Wednesday, and Friday fractionated radiation therapy; and palliative radiation therapy. Medical records were retrospectively reviewed for dogs that had been treated with radiation therapy for confirmed intranasal sarcoma. A total of 86 dogs met inclusion criteria. Overall median survival time for included dogs was 444 days. Median survival time for dogs with chondrosarcoma (n = 42) was 463 days, fibrosarcoma (n = 12) 379 days, osteosarcoma (n = 6) 624 days, and undifferentiated sarcoma (n = 22) 344 days. Dogs treated with daily-fractionated radiation therapy protocols; Monday, Wednesday and Friday fractionated radiation therapy protocols; and palliative radiation therapy protocols had median survival times of 641, 347, and 305 days, respectively. A significant difference in survival time was found for dogs receiving curative intent radiation therapy vs. palliative radiation therapy (P = 0.032). A significant difference in survival time was also found for dogs receiving daily-fractionated radiation therapy vs. Monday, Wednesday and Friday fractionated radiation therapy (P = 0.0134). Findings from this study support the use of curative intent radiation therapy for dogs with intranasal sarcoma. Future prospective, randomized trials are needed for confirmation of treatment benefits. © 2012 Veterinary Radiology & Ultrasound.

The Japanese Society of Gastroenterology (JSGE) revised the evidence-based clinical practice guidelines for peptic ulcer disease in 2014 and has created an English version. The revised guidelines consist of seven items: bleeding gastric and duodenal ulcers, Helicobacter pylori (H. pylori) eradication therapy, non-eradication therapy, drug-induced ulcer, non-H. pylori, non-nonsteroidal anti-inflammatory drug (NSAID) ulcer, surgical treatment, and conservative therapy for perforation and stenosis. Ninety clinical questions (CQs) were developed, and a literature search was performed for the CQs using the Medline, Cochrane, and Igaku Chuo Zasshi databases between 1983 and June 2012. The guideline was developed using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) system. Therapy is initially provided for ulcer complications. Perforation or stenosis is treated with surgery or conservatively. Ulcer bleeding is first treated by endoscopic hemostasis. If it fails, surgery or interventional radiology is chosen. Second, medical therapy is provided. In cases of NSAID-related ulcers, use of NSAIDs is stopped, and anti-ulcer therapy is provided. If NSAID use must continue, the ulcer is treated with a proton pump inhibitor (PPI) or prostaglandin analog. In cases with no NSAID use, H. pylori-positive patients receive eradication and anti-ulcer therapy. If first-line eradication therapy fails, second-line therapy is given. In cases of non-H. pylori, non-NSAID ulcers or H. pylori-positive patients with no indication for eradication therapy, non-eradication therapy is provided. The first choice is PPI therapy, and the second choice is histamine 2-receptor antagonist therapy. After initial therapy, maintenance therapy is provided to prevent ulcer relapse.
