Hybrid discourse practice and science learning

Kamberelis, George; Wehunt, Mary D.
2012-09-01
In this article, we report on a study of how creative linguistic practices (which we call hybrid discourse practices) were enacted by students in a fifth-grade science unit on barn owls and how these practices helped to produce a synergistic micro-community of scientific practice in the classroom that constituted a fertile space for students (and the teacher) to construct emergent but increasingly legitimate and dynamic disciplinary knowledges and identities. Our findings are important for the ways in which they demonstrate (a) how students use hybrid discourse practices to self-scaffold their work within complex curricular tasks and when they are not completely sure about how to enact these tasks (b) how hybrid discourse practices can promote inquiry orientations to science, (c) how hybrid discourse practices index new and powerful forms of science pedagogy, and (d) how hybrid discourse practices are relevant to more global issues such as the crucial roles of language fluency and creativity, which are known prerequisites for advanced science learning and which aid students in developing skills that are necessary for entry into science and technology careers.

Verbal play, or the playful manipulation of elements of language, is a pervasive component of social interaction, serving important interpersonal functions. We analyzed verbal play in the interactional discourse of ten healthy younger pairs and ten healthy older pairs as they completed a collaborative referencing task. A total of 1,893 verbal play episodes were coded. While there were no group differences in verbal play frequency, age-related differences in the quality and function of these episodes emerged. While older participants engaged in more complex, extended, and reciprocal episodes that supported the social nature of communicative interactions (e.g., teasing), younger participants were more likely to engage in verbal play episodes for the purpose of successful task completion. Despite these age-related variations in the deployment of verbal play, verbal play is a robust interactional discourse resource in healthy aging, highlighting an element of human cognition that does not appear to decline with age.

Use of Referential Discourse Contexts in L2 Offline and Online Sentence Processing.
Yang, Pi-Lan
2016-10-01
The present study aimed to investigate (a) the extent to which Chinese-speaking learners of English in Taiwan use referential noun phrase (NP) information contained in discourse contexts to complete ambiguous noun/verb fragments in a sentence completion task, and (b) whether and when they use the contexts to disambiguate main verb versus reduced relative clause (MV/RRC) ambiguities in real time. Results showed that unlike native English speakers, English learners did not create a marked increase in RRC completions in biasing two-NP-referent discourse contexts except for advanced learners. Nevertheless, like native speakers, the learners at elementary, intermediate, and advanced English proficiency levels all used the information in a later stage of resolving the MV/RRC ambiguities in real time. The delayed effect of referential context information observed suggests that L2 learners, like native speakers, are able to construct syntax-to-discourse mappings in real time. It also suggests that processing of syntactic information takes precedence over integration of syntactic information with discourse information during L1 and L2 online sentence processing.

Vocative intonation preferences are sensitive to politeness factors.
Borràs-Comes, Joan; Sichel-Bazin, Raféu; Prieto, Pilar
2015-03-01
Although intonation has been traditionally associated with the expression of attitudes and intentions on the part of the speaker, little is known about whether sociopragmatic factors, such as power or social distance, or situational ones, like physical distance or insistence, can constrain the use and felicity of pitch contours. This article investigates the felicity conditions underlying the choice of three vocative pitch contours in Central Catalan by means of two experiments, namely a production experiment based on the Discourse Completion Task (320 vocative contours produced by 20 speakers), and an acceptability judgment task in which 72 listeners were asked to rate the appropriateness match between a set of vocative contours and a previous discourse context (3,456 responses). The results from the two experiments show that both situational and social politeness factors govern the choice of vocative intonation. Finally, the results are discussed in line with the traditional classification of politeness strategies defined by Brown and Levinson, in the sense that the three intonation contours can be linked to negative, positive, and bald on-record politeness strategies.
Co-speech iconic gestures and visuo-spatial working memory.
Wu, Ying Choon; Coulson, Seana
2014-11-01
Three experiments tested the role of verbal versus visuo-spatial working memory in the comprehension of co-speech iconic gestures. In Experiment 1, participants viewed congruent discourse primes in which the speaker's gestures matched the information conveyed by his speech, and incongruent ones in which the semantic content of the speaker's gestures diverged from that in his speech. Discourse primes were followed by picture probes that participants judged as being either related or unrelated to the preceding clip. Performance on this picture probe classification task was faster and more accurate after congruent than incongruent discourse primes. The effect of discourse congruency on response times was linearly related to measures of visuo-spatial, but not verbal, working memory capacity, as participants with greater visuo-spatial WM capacity benefited more from congruent gestures. In Experiments 2 and 3, participants performed the same picture probe classification task under conditions of high and low loads on concurrent visuo-spatial (Experiment 2) and verbal (Experiment 3) memory tasks. Effects of discourse congruency and verbal WM load were additive, while effects of discourse congruency and visuo-spatial WM load were interactive. Results suggest that congruent co-speech gestures facilitate multi-modal language comprehension, and indicate an important role for visuo-spatial WM in these speech-gesture integration processes.

Verbal Play as an Interactional Discourse Resource in Early Stage Alzheimer’s Disease
Shune, Samantha; Duff, Melissa C.
2012-01-01
Background Verbal play, the creative and playful use of language to make puns, rhyme words, and tease, is a pervasive and enjoyable component of social communication and serves important interpersonal functions. The current study examines the use of verbal play in the communicative interactions of individuals with Alzheimer’s disease as part of a broader program of research on language-and-memory-in-use. Aims To document the frequency of verbal play in the communicative interactions of individuals with very mild Alzheimer’s disease (AD) and their familiar communication partners. To characterize the interactional forms, resources, and functions of playful episodes. Methods Using quantitative group comparisons and detailed discourse analysis, we analyzed verbal play in the interactional discourse of five participants with very mild AD and five healthy (demographically matched) comparison participants. Each participant interacted with a familiar partner while completing a collaborative referencing task, and with a researcher between task trials. Results A total of 1,098 verbal play episodes were coded. Despite being in the early stages of AD, all the AD participants used verbal play. There were no significant group differences in the frequency of verbal play episodes or in the interactional forms, resources, or functions of those playful episodes between AD and healthy comparison pair sessions. Conclusions The successful use of verbal play in the interactions of individuals with very mild AD and their partners highlights an area of preserved social communication. These findings represent an important step, both clinically and for research, in documenting the rich ways that individuals with early stage AD orchestrate interactionally meaningful communication with their partners through the use of interactional discourse resources like verbal play. This work also offers a promising clinical tool for tracking and targeting verbal play across disease progression. PMID:23129879

Mothers read stories to their children (N=41) aged between 3.3 years and 5.11 years old, and children then completed two false-belief tasks. One year later, mothers read a story to 37 of those children who were also given four tasks to assess their advanced understanding of mental states. Mothers' early use of cognitive verbs in picture-book reading correlated with their children's later understanding of mental states. Some pragmatic aspects of maternal input correlated with children's later outcomes. Two different factors in mothers' cognitive discourse were identified, suggesting a zone of proximal development in children's understanding of mental states.

Alzheimer's disease (AD) is characterized by impairments in memory and other cognitive functions such as language, which can be affected in all aspects including discourse. A picture description task is considered an effective way of obtaining a discourse sample whose key feature is the ability to retrieve appropriate lexical items. There is no consensus on findings showing that performance in content processing of spoken discourse deteriorates from the mildest phase of AD. To compare the quantity and quality of discourse among patients with mild to moderate AD and controls. A cross-sectional study was designed. Subjects aged 50 years and older of both sexes, with one year or more of education, were divided into three groups: control (CG), mild AD (ADG1) and moderate AD (ADG2). Participants were asked to describe the "cookie theft" picture. The total number of complete words spoken and information units (IU) were included in the analysis. There was no significant difference among groups in terms of age, schooling and sex. For number of words spoken, the CG performed significantly better than both the ADG 1 and ADG2, but no difference between the two latter groups was found. CG produced almost twice as many information units as the ADG1 and more than double that of the ADG2. Moreover, ADG2 patients had worse performance on IUs compared to the ADG1. Decreased performance in quantity and content of discourse was evident in patients with AD from the mildest phase, but only content (IU) continued to worsen with disease progression.

Most studies on bilingual language development focus on children’s second language (L2). Here, we investigated first language (L1) development of Polish-English early migrant bilinguals in four domains: vocabulary, grammar, phonological processing, and discourse. We first compared Polish language skills between bilinguals and their Polish non-migrant monolingual peers, and then investigated the influence of the cumulative exposure to L1 and L2 on bilinguals’ performance. We then examined whether high exposure to L1 could possibly minimize the gap between monolinguals and bilinguals. We analyzed data from 233 typically developing children (88 bilingual and 145 monolingual) aged 4;0 to 7;5 (years;months) on six language measures in Polish: receptive vocabulary, productive vocabulary, receptive grammar, productive grammar (sentence repetition), phonological processing (non-word repetition), and discourse abilities (narration). Information about language exposure was obtained via parental questionnaires. For each language task, we analyzed the data from the subsample of bilinguals who had completed all the tasks in question and from monolinguals matched one-on-one to the bilingual group on age, SES (measured by years of mother’s education), gender, non-verbal IQ, and short-term memory. The bilingual children scored lower than monolinguals in all language domains, except discourse. The group differences were more pronounced on the productive tasks (vocabulary, grammar, and phonological processing) and moderate on the receptive tasks (vocabulary and grammar). L1 exposure correlated positively with the vocabulary size and phonological processing. Grammar scores were not related to the levels of L1 exposure, but were predicted by general cognitive abilities. L2 exposure negatively influenced productive grammar in L1, suggesting possible L2 transfer effects on L1 grammatical performance. Children’s narrative skills benefitted from exposure to two languages: both L1 and L2 exposure influenced story structure scores in L1. Importantly, we did not find any evidence (in any of the tasks in which the gap was present) that the performance gap between monolinguals and bilinguals could be fully closed with high amounts of L1 input.

[Discourse analysis: research potentialities to gender violence].

2009-01-01
In the last few years we see the growing use of the terms 'discourse' and 'discourses analysis' in academic and research contexts, frequently without a precise definition. This fact opens space for critics and mistakes. The aim of this paper is to show a brief contextualization of discursive studies, as well as tasks/steps to Discourse Analysis process by the Social Construcionism perspective. As examples we used fragments of an interview with a Family Doctor about gender violence. In the results we detach the potential of Discourse Analysis to deconstruct the existing discourses to subsequently (re)construction in the way to a more holistic view about gender violence problem.

This study examined whether young children with typical language development (TL) and children with language impairment (LI) make emotion inferences online during the process of discourse comprehension, identified variables that predict emotion inferencing, and explored the relationship of these variables to social competence. Preschool children (16 TL and 16 LI) watched narrated videos designed to activate knowledge about a particular emotional state. Following each story, children named a facial expression that either matched or did not match the anticipated emotion. Several experimental tasks examined linguistic and nonlinguistic abilities. Finally, each child's teacher completed a measure of social competence. Children with TL named expressions significantly more slowly in the mismatched condition than in the matched condition, whereas children with LI did not differ in response times between the conditions. Language and vocal response time measures were related to emotion inferencing ability, and this ability predicted social competence scores. The findings suggest that children with TL are inferring emotions during the comprehension process, whereas children with LI often fail to make these inferences. Making emotion inferences is related to discourse comprehension and to social competence in children. The current findings provide evidence that language and vocal response time measures predicted inferencing ability and suggest that additional factors may influence discourse inferencing and social competence.

Patient or consumer? The colonization of the psychiatric clinic.
Evans, Alicia M
2005-12-01
Information is given a privileged place in the psychiatric clinic, as illustrated by the prevalence and volume of data to be collected and forms to be completed by psychiatric nurses. Information though is different to knowledge. The present paper argues that information is part of a managerial discourse that implies commodification whereas knowledge is part of a clinical discourse that allows room for the suffering of the patient. Information belongs to the discourse of managerialism, one that positions the patient as customer/consumer and in doing so renders them unsuffering. The patient's suffering is silenced by their construction as a consumer. The discourse of managerialism seeks a complete data set of information. By way of contrast, another discourse, that of psychoanalysis offers the institution the idea that there are always holes, gaps, and uncertainty. The idea of uncertainty, gaps, things remaining unknown and a limit sits uncomfortably with the dominant discourse of managerialism; one that demands no limits, complete data sets, and many satisfied customers. This market model of managerialism denies the potential of the therapeutic relationship; that something curative might be produced via the transference. In addition, the managerialist discourse potentially positions the patient as both illegitimate and unsuffering.

Neuroimaging studies have found that theory of mind (ToM) and discourse comprehension involve similar brain regions. These brain regions may be associated with three cognitive components that are necessarily or frequently involved in ToM and discourse comprehension, including social concept representation and retrieval, domain-general semantic integration, and domain-specific integration of social semantic contents. Using fMRI, we investigated the neural correlates of these three cognitive components by exploring how discourse topic (social/nonsocial) and discourse processing period (ending/beginning) modulate brain activation in a discourse comprehension (and also ToM) task. Different sets of brain areas showed sensitivity to discourse topic, discourse processing period, and the interaction between them, respectively. The most novel finding was that the right temporoparietal junction and middle temporal gyrus showed sensitivity to discourse processing period only during social discourse comprehension, indicating that they selectively contribute to domain-specific semantic integration. Our finding indicates how different domains of semantic information are processed and integrated in the brain and provides new insights into the neural correlates of ToM and discourse comprehension.

Purpose The discourse of healthy older adults is commonly described as being lengthy and off-topic and is thought to be associated with a general cognitive decline that accompanies healthy aging. The purpose of this preliminary study was to investigate the overall decline in attention associated with healthy aging and its relationship to instances of off-topic speech (OTS). Method Thirty cognitively healthy adults divided into 5 age cohorts (40–80) completed cognitive measures of attention and several discourse tasks that included recounting personal events. Results Cohorts differed significantly with respect to the measures of attention. However, no significant differences in the incidence of OTS were detected between the cohorts. Attention and the incidence of OTS were not significantly correlated within any of the cohorts. Conclusion No significant differences in the incidence of OTS and its relation to attention measures were found. However, the relationship between age-related declines in attention and increased OTS approached significance, suggesting the need for further study. PMID:23420319

In both vocal and sign languages, we can distinguish word-, sentence-, and discourse-level integration in terms of hierarchical processes, which integrate various elements into another higher level of constructs. In the present study, we used magnetic resonance imaging and voxel-based morphometry (VBM) to test three language tasks in Japanese Sign Language (JSL): word-level (Word), sentence-level (Sent), and discourse-level (Disc) decision tasks. We analyzed cortical activity and gray matter (GM) volumes of Deaf signers, and clarified three major points. First, we found that the activated regions in the frontal language areas gradually expanded in the dorso-ventral axis, corresponding to a difference in linguistic units for the three tasks. Moreover, the activations in each region of the frontal language areas were incrementally modulated with the level of linguistic integration. These dual mechanisms of the frontal language areas may reflect a basic organization principle of hierarchically integrating linguistic information. Secondly, activations in the lateral premotor cortex and inferior frontal gyrus were left-lateralized. Direct comparisons among the language tasks exhibited more focal activation in these regions, suggesting their functional localization. Thirdly, we found significantly positive correlations between individual task performances and GM volumes in localized regions, even when the ages of acquisition (AOAs) of JSL and Japanese were factored out. More specifically, correlations with the performances of the Word and Sent tasks were found in the left precentral/postcentral gyrus and insula, respectively, while correlations with those of the Disc task were found in the left ventral inferior frontal gyrus and precuneus. The unification of functional and anatomical studies would thus be fruitful for understanding human language systems from the aspects of both universality and individuality. PMID:24155706

This case study aimed to determine the nature of student interactions in small groups in an elementary classroom utilizing the Science Writing Heuristic approach. Fifth grade students were audio-recorded over four units of study while working in small groups to generate knowledge claims after conducting student-directed investigations. Analysis consisted of (1) identifying amount of on/off task talk, (2) categorizing on-task talk as generative (talk associated with generating an argument) or representational (talk associated with representing an argument in a final written form), (3) characterizing the generative components of argument, and (4) determining the functions of language used. Results indicate that students were on task 98% of the time. Students engaged in generative talk an average of 25% of the time and representational talk an average of 71% of the time. Students engaged in components of Toulmin's model of argument, but challenging of each other's ideas was not commonplace. Talk was dominated by the informative function (representing one's ideas) of language as it was found 78.3% of the time and to a lesser extent (11.7%) the heuristic function (inquiring through questions). These functions appear to be intimately tied to the task of generating knowledge claims in small groups. The results suggest that both talking and writing are critical to using science discourse as an embedded strategy to learning science. Further, nature and structure of the task are important pedagogical considerations when moving students toward participation in science discourse.

This study evaluates how proposition density can differentiate between persons with aphasia (PWA) and individuals in a control group, as well as among subtypes of aphasia, on the basis of procedural discourse and personal narratives collected from large samples of participants. Participants were 195 PWA and 168 individuals in a control group from the AphasiaBank database. PWA represented 6 aphasia types on the basis of the Western Aphasia Battery-Revised (Kertesz, 2006). Narrative samples were stroke stories for PWA and illness or injury stories for individuals in the control group. Procedural samples were from the peanut-butter-and-jelly-sandwich task. Language samples were transcribed using Codes for the Human Analysis of Transcripts (MacWhinney, 2000) and analyzed using Computerized Language Analysis (MacWhinney, 2000), which automatically computes proposition density (PD) using rules developed for automatic PD measurement by the Computerized Propositional Idea Density Rater program (Brown, Snodgrass, & Covington, 2007; Covington, 2007). Participants in the control group scored significantly higher than PWA on both tasks. PD scores were significantly different among the aphasia types for both tasks. Pairwise comparisons for both discourse tasks revealed that PD scores for the Broca's group were significantly lower than those for all groups except Transcortical Motor. No significant quadratic or linear association between PD and severity was found. Proposition density is differentially sensitive to aphasia type and most clearly differentiates individuals with Broca's aphasia from the other groups.

Who's Who? Memory updating and character reference in children's narratives.
Whitely, Cristy; Colozzo, Paola
2013-10-01
The capacity to update and monitor the contents of working memory is an executive function presumed to play a critical role in language processing. The current study used an individual differences approach to consider the relationship between memory updating and accurate reference to story characters in the narratives of typically developing children. English-speaking children from kindergarten to grade 2 ( N = 63; M age = 7.0 years) completed updating tasks, short-term memory tasks, and narrative productions. The authors used multiple regression to test whether updating accounted for independent variability in referential adequacy. The capacity to update working memory was related to adequate character reference beyond the effects of age and of short-term memory capacity, with the strongest relationship emerging for maintaining reference over multiple utterances. This individual differences study is the first to show a link between updating and performance in a discourse production task for young school-age children. The findings contribute to the growing body of research investigating the role of working memory in shaping language production. This study invites extension to children of different ages and language abilities as well as to other language production tasks.

Purpose: The current study sought to investigate the separate effects of dysarthria and cognitive status on global speech timing, speech hesitation, and linguistic complexity characteristics and how these speech behaviors impose on listener impressions for three connected speech tasks presumed to differ in cognitive-linguistic demand for four carefully defined speaker groups; 1) MS with cognitive deficits (MSCI), 2) MS with clinically diagnosed dysarthria and intact cognition (MSDYS), 3) MS without dysarthria or cognitive deficits (MS), and 4) healthy talkers (CON). The relationship between neuropsychological test scores and speech-language production and perceptual variables for speakers with cognitive deficits was also explored. Methods: 48 speakers, including 36 individuals reporting a neurological diagnosis of MS and 12 healthy talkers participated. The three MS groups and control group each contained 12 speakers (8 women and 4 men). Cognitive function was quantified using standard clinical tests of memory, information processing speed, and executive function. A standard z-score of ≤ -1.50 indicated deficits in a given cognitive domain. Three certified speech-language pathologists determined the clinical diagnosis of dysarthria for speakers with MS. Experimental speech tasks of interest included audio-recordings of an oral reading of the Grandfather passage and two spontaneous speech samples in the form of Familiar and Unfamiliar descriptive discourse. Various measures of spoken language were of interest. Suprasegmental acoustic measures included speech and articulatory rate. Linguistic speech hesitation measures included pause frequency (i.e., silent and filled pauses), mean silent pause duration, grammatical appropriateness of pauses, and interjection frequency. For the two discourse samples, three standard measures of language complexity were obtained including subordination index, inter-sentence cohesion adequacy, and lexical diversity. Ten listeners judged each speech sample using the perceptual construct of Speech Severity using a visual analog scale. Additional measures obtained to describe participants included the Sentence Intelligibility Test (SIT), the 10-item Communication Participation Item Bank (CPIB), and standard biopsychosocial measures of depression (Beck Depression Inventory-Fast Screen; BDI-FS), fatigue (Fatigue Severity Scale; FSS), and overall disease severity (Expanded Disability Status Scale; EDSS). Healthy controls completed all measures, with the exception of the CPIB and EDSS. All data were analyzed using standard, descriptive and parametric statistics. For the MSCI group, the relationship between neuropsychological test scores and speech-language variables were explored for each speech task using Pearson correlations. The relationship between neuropsychological test scores and Speech Severity also was explored. Results and Discussion: Topic familiarity for descriptive discourse did not strongly influence speech production or perceptual variables; however, results indicated predicted task-related differences for some spoken language measures. With the exception of the MSCI group, all speaker groups produced the same or slower global speech timing (i.e., speech and articulatory rates), more silent and filled pauses, more grammatical and longer silent pause durations in spontaneous discourse compared to reading aloud. Results revealed no appreciable task differences for linguistic complexity measures. Results indicated group differences for speech rate. The MSCI group produced significantly faster speech rates compared to the MSDYS group. Both the MSDYS and the MSCI groups were judged to have significantly poorer perceived Speech Severity compared to typically aging adults. The Task x Group interaction was only significant for the number of silent pauses. The MSDYS group produced fewer silent pauses in spontaneous speech and more silent pauses in the reading task compared to other groups. Finally, correlation analysis revealed moderate relationships between neuropsychological test scores and speech hesitation measures, within the MSCI group. Slower information processing and poorer memory were significantly correlated with more silent pauses and poorer executive function was associated with fewer filled pauses in the Unfamiliar discourse task. Results have both clinical and theoretical implications. Overall, clinicians should demonstrate caution when interpreting global measures of speech timing and perceptual measures in the absence of information about cognitive ability. Results also have implications for a comprehensive model of spoken language incorporating cognitive, linguistic, and motor variables.

Coarse coding and discourse comprehension in adults with right hemisphere brain damage
Tompkins, Connie A.; Scharp, Victoria L.; Meigh, Kimberly M.; Fassbinder, Wiltrud
2009-01-01
Background Various investigators suggest that some discourse-level comprehension difficulties in adults with right hemisphere brain damage (RHD) have a lexical-semantic basis. As words are processed, the intact right hemisphere arouses and sustains activation of a wide-ranging network of secondary or peripheral meanings and features—a phenomenon dubbed “coarse coding”. Coarse coding impairment has been postulated to underpin some prototypical RHD comprehension deficits, such as difficulties with nonliteral language interpretation, discourse integration, some kinds of inference generation, and recovery when a reinterpretation is needed. To date, however, no studies have addressed the hypothesised link between coarse coding deficit and discourse comprehension in RHD. Aims The current investigation examined whether coarse coding was related to performance on two measures of narrative comprehension in adults with RHD. Methods & Procedures Participants were 32 adults with unilateral RHD from cerebrovascular accident, and 38 adults without brain damage. Coarse coding was operationalised as poor activation of peripheral/weakly related semantic features of words. For the coarse coding assessment, participants listened to spoken sentences that ended in a concrete noun. Each sentence was followed by a spoken target phoneme string. Targets were subordinate semantic features of the sentence-final nouns that were incompatible with their dominant mental representations (e.g., “rotten” for apple). Targets were presented at two post-noun intervals. A lexical decision task was used to gauge both early activation and maintenance of activation of these weakly related semantic features. One of the narrative tasks assessed comprehension of implied main ideas and details, while the other indexed high-level inferencing and integration. Both comprehension tasks were presented auditorily. For all tasks, accuracy of performance was the dependent measure. Correlations were computed within the RHD group between both the early and late coarse coding measures and the two discourse measures. Additionally, ANCOVA and independent t-tests were used to compare both early and sustained coarse coding in subgroups of good and poor RHD comprehenders. Outcomes & Results The group with RHD was less accurate than the control group on all measures. The finding of coarse coding impairment (difficulty activating/sustaining activation of a word’s peripheral features) may appear to contradict prior evidence of RHD suppression deficit (prolonged activation for context-inappropriate meanings of words). However, the sentence contexts in this study were unbiased and thus did not provide an appropriate test of suppression function. Correlations between coarse coding and the discourse measures were small and nonsignificant. There were no differences in coarse coding between RHD comprehension subgroups on the high-level inferencing task. There was also no distinction in early coarse coding for subgroups based on comprehension of implied main ideas and details. But for these same subgroups, there was a difference in sustained coarse coding. Poorer RHD comprehenders of implied information from discourse were also poorer at maintaining activation for semantically distant features of concrete nouns. Conclusions This study provides evidence of a variant of the postulated link between coarse coding and discourse comprehension in RHD. Specifically, adults with RHD who were particularly poor at sustaining activation for peripheral semantic features of nouns were also relatively poor comprehenders of implied information from narratives.

Referential choice across the lifespan: why children and elderly adults produce ambiguous pronouns
Hendriks, Petra; Koster, Charlotte; Hoeks, John C.J.
2013-01-01
In this study, children, young adults and elderly adults were tested in production and comprehension tasks assessing referential choice. Our aims were (1) to determine whether speakers egocentrically base their referential choice on the preceding linguistic discourse or also take into account the perspective of a hypothetical listener and (2) whether the possible impact of perspective taking on referential choice changes with increasing age, with its associated changes in cognitive capacity. In the production task, participants described picture-based stories featuring two characters of the same gender, making it necessary to use unambiguous forms; in the comprehension task, participants interpreted potentially ambiguous pronouns at the end of similar orally presented stories. Young adults (aged 18–35) were highly sensitive to the informational needs of hypothetical conversational partners in their production and comprehension of referring expressions. In contrast, children (aged 4–7) did not take into account possible conversational partners and tended to use pronouns for all given referents, leading to the production of ambiguous pronouns that are unrecoverable for a listener. This was mirrored in the outcome of the comprehension task, where children were insensitive to the shift of discourse topic marked by the speaker. The elderly adults (aged 69–87) behaved differently from both young adults and children. They showed a clear sensitivity to the other person's perspective in both production and comprehension, but appeared to lack the necessary cognitive capacities to keep track of the prominence of discourse referents, producing more potentially ambiguous pronouns than young adults, though fewer than children. In conclusion then, referential choice seems to depend on perspective taking in language, which develops with increasing linguistic experience and cognitive capacity, but also on the ability to keep track of the prominence of discourse referents, which is gradually lost with older age.

This study investigated the impact of the use of computer technology on the enactment of inquiry in a sixth grade science classroom. Participants were 42 students (38% female) enrolled in two sections of the classroom and taught by a technology-enthusiast instructor. Data were collected over the course of 4 months during which several inquiry activities were completed, some of which were supported with the use of technology. Non-participant observation, classroom videotaping, and semi-structured and critical-incident interviews were used to collect data. The results indicated that the technology in use worked to restrict rather than promote inquiry in the participant classroom. In the presence of computers, group activities became more structured with a focus on sharing tasks and accounting for individual responsibility, and less time was dedicated to group discourse with a marked decrease in critical, meaning-making discourse. The views and beliefs of teachers and students in relation to their specific contexts moderate the potential of technology in supporting inquiry teaching and learning and should be factored both in teacher training and attempts to integrate technology in science teaching.

The establishment of reference is essential to language comprehension. The goal of this study was to examine listeners’ sensitivity to referential ambiguity as a function of individual variation in attention, working memory capacity, and verbal ability. Participants listened to stories in which two entities were introduced that were either very similar (e.g., two oaks) or less similar (e.g., one oak and one elm). The manipulation rendered an anaphor in a subsequent sentence (e.g., oak) ambiguous or unambiguous. EEG was recorded as listeners comprehended the story, after which participants completed tasks to assess working memory, verbal ability, and the ability to use context in task performance. Power in the alpha and theta frequency bands when listeners received critical information about the discourse entities (e.g., oaks) was used to index attention and the involvement of the working memory system in processing the entities. These measures were then used to predict an ERP component that is sensitive to referential ambiguity, the Nref, which was recorded when listeners received the anaphor. Nref amplitude at the anaphor was predicted by alpha power during the earlier critical sentence: Individuals with increased alpha power in ambiguous compared with unambiguous stories were less sensitive to the anaphor's ambiguity. Verbal ability was also predictive of greater sensitivity to referential ambiguity. Finally, increased theta power in the ambiguous compared with unambiguous condition was associated with higher working-memory span. These results highlight the role of attention and working memory in referential processing during listening comprehension. PMID:26401815

In order to reflect the research achievements of acupuncture on international academic community and study the acupuncture international discourse power from 2007 through 2017, we used text analysis software to analyze 5668 papers that focusing on acupuncture research in the recent 10 years. The results show that international acupuncture research trend has been formed, the research force diverges to the rest of the world with "China-America" as the center, and the study focuses on its sight and the interaction between China and foreign countries is good. Under the perspective of international discourse power, the construction of the national communication platform, the cultivation of academic centers and research fields, and the interaction with international research forces will enhance the quality of Chinese acupuncture research, and these will become an important task in enhancing the international discourse power of Chinese acupuncture.

This longitudinal study investigated the developmental trajectory of discourse skills and theory of mind in 57 children with autism. Children were tested at two time points spaced 1 year apart. Each year they provided a natural language sample while interacting with one parent, and were given standardized vocabulary measures and a developmentally sequenced battery of theory of mind tasks. The language samples were coded for conversational skills, specifically the child's use of topic-related contingent utterances. Children with autism made significant gains over 1 year in the ability to maintain a topic of discourse. Hierarchical regression analyses demonstrated that theory of mind skills contributed unique variance to individual differences in contingent discourse ability and vice versa, when measured concurrently; however, they did not predict longitudinal changes. The findings offer some empirical support for the hypothesis that theory of mind is linked to communicative competence in children with autism.

This is the first study of the effect of topiramate on linguistic behavior and verbal recall using a computational linguistics system for automated language and speech analysis to detect and quantify drug-induced changes in speech recorded during discourse-level tasks. Healthy volunteers were administered a single, 100-mg oral dose of topiramate in two double-blind, randomized, placebo-controlled, crossover studies. Subjects' topiramate plasma levels ranged from 0.23 to 2.81 μg/mL. We found a significant association between topiramate levels and impairment on measures of verbal fluency elicited during a picture description task, correct number of words recalled on a paragraph recall test, and reaction time recorded during a working memory task. Using the tools of clinical pharmacology and computational linguistics, we elucidated the relationship between the determinants of a drug's disposition as reflected in plasma concentrations and their impact on cognitive functioning as reflected in spoken language discourse.

The insatisfactory completeness of the variables in the Death Certificate (DC) makes it difficult to obtain specific perinatal mortality indicators. To assess the social representation of physicians about the perinatal DC. Twenty-five physicians were interviewed in 15 hospitals in the city of São Paulo, in 2009. Qualitative analysis was performed with the Collective Subject Discourse technique. The DC is primarily considered according to its legal aspect. Physicians feel responsible for fulfilling the cause of death. The majority of them reported receiving help from other professionals to complete information on maternal characteristics and identification variables. There is lack of information on the mother's pre-natal conditions, which can make it difficult to identify the perinatal cause of death, mainly in the Unified Health System (SUS) hospitals. Some participants received specific DC training only when attending medical schools. The organization of medical work may affect the completion of the DC, especially in hospitals from SUS. Other professionals contributed to this task and their training can improve the quality of information.

During a narrative discourse, accessibility of the referents is rarely fixed once and for all. Rather, each referent varies in accessibility as the discourse unfolds, depending on the presence and prominence of the other referents. This leads the speaker to use various referential expressions to refer to the main protagonists of the story at different moments in the narrative. This study relies on a new, collaborative storytelling in sequence task designed to assess how speakers adjust their referential choices when they refer to different characters at specific discourse stages corresponding to the introduction, maintaining, or shift of the character in focus, in increasingly complex referential contexts. Referential complexity of the stories was manipulated through variations in the number of characters (1 vs. 2) and, for stories in which there were two characters, in their ambiguity in gender (different vs. same gender). Data were coded for the type of reference markers as well as the type of reference content (i.e., the extent of the information provided in the referential expression). Results showed that, beyond the expected effects of discourse stages on reference markers (more indefinite markers at the introduction stage, more pronouns at the maintaining stage, and more definite markers at the shift stage), the number of characters and their ambiguity in gender also modulated speakers' referential choices at specific discourse stages, For the maintaining stage, an effect of the number of characters was observed for the use of pronouns and of definite markers, with more pronouns when there was a single character, sometimes replaced by definite expressions when two characters were present in the story. For the shift stage, an effect of gender ambiguity was specifically noted for the reference content with more specific information provided in the referential expression when there was referential ambiguity. Reference content is an aspect of referential marking that is rarely addressed in a narrative context, yet it revealed a quite flexible referential behavior by the speakers.

Today, a considerable proportion of the public political discourse on nationwide elections proceeds in Online Social Networks. Through analyzing this content, we can discover the major themes that prevailed during the discussion, investigate the temporal variation of positive and negative sentiment and examine the semantic proximity of these themes. According to existing studies, the results of similar tasks are heavily dependent on the quality and completeness of dictionaries for linguistic preprocessing, entity discovery and sentiment analysis. Additionally, noise reduction is achieved with methods for sarcasm detection and correction. Here we report on the application of these methods on the complete corpus of tweets regarding two local electoral events of worldwide impact: the Greek referendum of 2015 and the subsequent legislative elections. To this end, we compiled novel dictionaries for sentiment and entity detection for the Greek language tailored to these events. We subsequently performed volume analysis, sentiment analysis, sarcasm correction and topic modeling. Results showed that there was a strong anti-austerity sentiment accompanied with a critical view on European and Greek political actions. PMID:29088263

Discourse from speakers with dementia and aphasia is associated with comparable but not identical deficits, necessitating appropriate methods to differentiate them. The current study aims to validate the Main Concept Analysis (MCA) to be used for eliciting and quantifying discourse among native typical English speakers and to establish its norm, and investigate the validity and sensitivity of the MCA to compare discourse produced by individuals with fluent aphasia, non-fluent aphasia, or dementia of Alzheimer's type (DAT), and unimpaired elderly. Discourse elicited through a sequential picture description task was collected from 60 unimpaired participants to determine the MCA scoring criteria; 12 speakers with fluent aphasia, 12 with non-fluent aphasia, 13 with DAT, and 20 elderly participants from the healthy group were compared on the finalized MCA. Results of MANOVA revealed significant univariate omnibus effects of speaker group as an independent variable on each main concept index. MCA profiles differed significantly between all participant groups except dementia versus fluent aphasia. Correlations between the MCA performances and the Western Aphasia Battery and Cognitive Linguistic Quick Test were found to be statistically significant among the clinical groups. The MCA was appropriate to be used among native speakers of English. The results also provided further empirical evidence of discourse deficits in aphasia and dementia. Practitioners can use the MCA to evaluate discourse production systemically and objectively.
The influence of democratic racism in nursing inquiry.
Hilario, Carla T; Browne, Annette J; McFadden, Alysha
2018-01-01
Neoliberal ideology and exclusionary policies based on racialized identities characterize the current contexts in North America and Western Europe. Nursing knowledge cannot be abstracted from social, political and historical contexts; the task of examining the influence of race and racial ideologies on disciplinary knowledge and inquiry therefore remains an important task. Contemporary analyses of the role and responsibility of the discipline in addressing race-based health and social inequities as a focus of nursing inquiry remain underdeveloped. In this article, we examine nursing's engagement with ideas about race and racism and explore the ways in which nursing knowledge and inquiry have been influenced by race-based ideological discourses. Drawing on Henry and Tator's framework of democratic racism, we consider how strategic discursive responses-the discourses of individualism, multiculturalism, colour-blindness, political correctness and denial-have been deployed within nursing knowledge and inquiry to reinforce the belief in an essentially fair and just society while avoiding the need to acknowledge the persistence of racist discourses and ideologies. Greater theoretical, conceptual and methodological clarity regarding race, racialization and related concepts in nursing inquiry is needed to address health and social inequities. © 2017 John Wiley & Sons Ltd.

Although the positive effects of iconic gestures on word recall and comprehension by children have been clearly established, less is known about the benefits of beat gestures (rhythmic hand/arm movements produced together with prominent prosody). This study investigated (a) whether beat gestures combined with prosodic information help children recall contrastively focused words as well as information related to those words in a child-directed discourse (Experiment 1) and (b) whether the presence of beat gestures helps children comprehend a narrative discourse (Experiment 2). In Experiment 1, 51 4-year-olds were exposed to a total of three short stories with contrastive words presented in three conditions, namely with prominence in both speech and gesture, prominence in speech only, and nonprominent speech. Results of a recall task showed that (a) children remembered more words when exposed to prominence in both speech and gesture than in either of the other two conditions and that (b) children were more likely to remember information related to those words when the words were associated with beat gestures. In Experiment 2, 55 5- and 6-year-olds were presented with six narratives with target items either produced with prosodic prominence but no beat gestures or produced with both prosodic prominence and beat gestures. Results of a comprehension task demonstrated that stories told with beat gestures were comprehended better by children. Together, these results constitute evidence that beat gestures help preschoolers not only to recall discourse information but also to comprehend it. Copyright © 2018 Elsevier Inc.

2012-01-01
Purpose The purpose of the study was to examine the relationships among measures of comprehension and production for stories depicted in wordless pictures books and measures of memory and attention for 2 age groups. Method Sixty cognitively healthy adults participated. They consisted of two groups—young adults (20–29 years of age) and older adults (70–89 years of age). Participants completed cognitive measures and several discourse tasks; these included telling stories depicted in wordless picture books and answering multiple-choice comprehension questions pertaining to the story. Results The 2 groups did not differ significantly for proportion of story propositions conveyed; however, the younger group performed significantly better on the comprehension measure as compared with the older group. Only the older group demonstrated a statistically significant relationship between the story measures. Performance on the production and comprehension measures significantly correlated with performance on the cognitive measures for the older group but not for the younger group. Conclusions The relationship between adults’ comprehension of stimuli used to elicit narrative production samples and their narrative productions differed across the life span, suggesting that discourse processing performance changes in healthy aging. Finally, the study’s findings suggest that memory and attention contribute to older adults’ story processing performance. PMID:21106701

Discourse comprehension is at the core of communication capabilities, making it an important component of elderly populations' quality of life. The aim of this study is to evaluate changes in discourse comprehension and the underlying brain activity. Thirty-six participants read short stories and answered related probes in three conditions: micropropositions, macropropositions and situation models. Using near-infrared spectroscopy (NIRS), the variation in oxyhemoglobin (HbO 2 ) and deoxyhemoglobin (HbR) concentrations was assessed throughout the task. The results revealed that the older adults performed with equivalent accuracy to the young ones at the macroproposition level of discourse comprehension, but were less accurate at the microproposition and situation model levels. Similar to what is described in the compensation-related utilization of neural circuits hypothesis (CRUNCH) model, older participants tended to have greater activation in the left dorsolateral prefrontal cortex while reading in all conditions. Although it did not enable them to perform similarly to younger participants in all conditions, this over-activation could be interpreted as a compensation mechanism.

The role of linguistic experience in the processing of probabilistic information in production.
Gustafson, Erin; Goldrick, Matthew
2018-01-01
Speakers track the probability that a word will occur in a particular context and utilize this information during phonetic processing. For example, content words that have high probability within a discourse tend to be realized with reduced acoustic/articulatory properties. Such probabilistic information may influence L1 and L2 speech processing in distinct ways (reflecting differences in linguistic experience across groups and the overall difficulty of L2 speech processing). To examine this issue, L1 and L2 speakers performed a referential communication task, describing sequences of simple actions. The two groups of speakers showed similar effects of discourse-dependent probabilistic information on production, suggesting that L2 speakers can successfully track discourse-dependent probabilities and use such information to modulate phonetic processing.
Using NIAM to capture time dependencies in a domain of discourse

Becker, S.D.
1994-07-01
This paper addresses the issues surrounding the use of NIAM to capture time dependencies in a domain of discourse. The NIAM concepts that support capturing time dependencies are in the event and process portions of the NIAM metamodel, which are the portions most poorly supported by a well-established methodology. This lack of methodological support is a potentially serious handicap in any attempt to apply NIAM to a domain of discourse in which time dependencies are a central issue. However, the capability that NIAM provides for validating and verifying the elementary facts in the domain may reduce the magnitude of themore » event/process-specification task to a level at which it could be effectively handled even without strong methodological support.« less

The purpose of this study was to examine the preliminary efficacy of Attentive Reading and Constrained Summarization-Written (ARCS-W) in people with mild aphasia. ARCS-W adapts an existing treatment, ARCS (Rogalski & Edmonds, 2008), to address discourse level writing in mild aphasia. ARCS-W focuses on the cognitive and linguistic skills required for discourse production. This study was a within-subject pre-postdesign. Three people with mild aphasia participated. ARCS-W integrates attentive reading or listening with constrained summarization of discourse level material in spoken and written modalities. Outcomes included macro- (main concepts) and microlinguistic (correct information units, complete utterances) discourse measures, confrontation naming, aphasia severity, and functional communication. All 3 participants demonstrated some generalization to untrained spoken and written discourse at the word, sentence, and text levels. Reduced aphasia severity and/or increased functional communication and confrontation naming were also observed in some participants. The findings of this study provide preliminary evidence of the efficacy of ARCS-W to improve spoken and written discourse in mild aphasia. Different generalization patterns suggest different mechanisms of improvement. Further research and replication are required to better understand how ARCS-W can impact discourse abilities.

The purpose of this study was to investigate the relationship between prospective teachers' (PTs) instructional practises and their efficacy beliefs in classroom management and mathematics teaching. A sequential, explanatory mixed-methods design was employed. Results from efficacy surveys, implemented with 54 PTs were linked to a sample of teachers' instructional practises during the qualitative phase. In this phase, video-recorded lessons were analysed based on tasks, representations, discourse, and classroom management. Findings indicate that PTs with higher levels of mathematics teaching efficacy taught lessons characterised by tasks of higher cognitive demand, extended student explanations, student-to-student discourse, and explicit connections between representations. Classroom management efficacy seems to bear influence on the utilised grouping structures. These findings support explicit attention to PTs' mathematics teaching and classroom management efficacy throughout teacher preparation and a need for formative feedback to inform development of beliefs about teaching practises.

Patients with schizophrenia (SZ) often display social cognition disorders, including Theory of Mind (ToM) impairments and communication disruptions. Thought language disorders appear to be primarily a disruption of pragmatics, SZ can also experience difficulties at other linguistic levels including the prosodic one. Here, using an interactive paradigm, we showed that SZ individuals did not use prosodic phrasing to encode the contrastive status of discourse referents in French. We used a semi-spontaneous task to elicit noun-adjective pairs in which the noun in the second noun-adjective fragment was identical to the noun in the first fragment (e.g., BONBONS marron “brown candies” vs. BONBONS violets “purple candies”) or could contrast with it (e.g., BOUGIES violettes “purple candles” vs. BONBONS violets “purple candies”). We found that healthy controls parsed the target noun in the second noun-adjective fragment separately from the color adjective, to warn their interlocutor that this noun constituted a contrastive entity (e.g., BOUGIES violettes followed by [BONBONS] [violets]) compared to when it referred to the same object as in the first fragment (e.g., BONBONS marron followed by [BONBONS violets]). On the contrary, SZ individuals did not use prosodic phrasing to encode contrastive status of target nouns. In addition, SZ's difficulties to use prosody of contrast were correlated to their score in a classical ToM task (i.e., the hinting task). Taken together, our data provide evidence that SZ patients exhibit difficulties to prosodically encode discourse statuses and sketch a potential relationship between ToM and the use of linguistic prosody.

Previous studies have suggested that focusing an element can enhance the activation of the focused element and bring about a number of processing benefits. However, whether and how this local prominence of information interacts with global discourse organization remains unclear. In the present study, we addressed this issue in two experiments. Readers were presented with four-sentence discourses. The first sentence of each discourse contained a critical word that was either focused or unfocused in relation to a wh-question preceding the discourse. The second sentence either maintained or shifted the topic of the first sentence. Participants were told to read for comprehension and for a probe recognition task in which the memory of the critical words was tested. In Experiment 1, when the probe words were tested immediately after the point of topic shift, we found shorter response times for the focused critical words than the unfocused ones regardless of topic manipulation. However, in Experiment 2, when the probe words were tested two sentences away from the point of topic shift, we found the facilitation effect of focus only in the topic-maintained discourses, but not in the topic-shifted discourses. This suggests that the facilitation effect of focus was not immediately suppressed at the point of topic shifting, but when additional information was added to the new topic. Our findings provide evidence for the dynamic interplay between global topic structure and local salience of information and have important implications on how activation of information fluctuates in mental representation.

Working in small groups to solve problems is an instructional strategy that allows university students in science, technology, engineering, and mathematics disciplines the opportunity to practice interpersonal and professional skills while gaining and applying discipline-specific content knowledge. Previous research indicates that not all group work prompts result in the same experiences for students. In this study we posed two types of prompts (guided and open) to undergraduate engineering students in a statics course as they participated in group work projects. We measured student discourse, student performance, and perceptions of group work. We found that guided prompts were associated with higher-level discourse and higher performance (project scores) than open prompts. Students engaged in guided prompts were more likely to discuss distribution of labour and design/calculation details of their projects than when students responded to open prompts. We posit that guided prompts, which more clearly articulate expectations of students, help students determine how to divide tasks amongst themselves and, subsequently, jump to higher levels of discourse.
What happened (and what didn’t): Discourse constraints on encoding of plausible alternatives
Fraundorf, Scott H.; Benjamin, Aaron S.; Watson, Duane G.
2013-01-01
Three experiments investigated how font emphasis influences reading and remembering discourse. Although past work suggests that contrastive pitch contours benefit memory by promoting encoding of salient alternatives, it is unclear both whether this effect generalizes to other forms of linguistic prominence and how the set of alternatives is constrained. Participants read discourses in which some true propositions had salient alternatives (e.g., British scientists found the endangered monkey when the discourse also mentioned French scientists) and completed a recognition memory test. In Experiments 1 and 2, font emphasis in the initial presentation increased participants’ ability to later reject false statements about salient alternatives but not about unmentioned items (e.g., Portuguese scientists). In Experiment 3, font emphasis helped reject false statements about plausible alternatives, but not about less plausible alternatives that were nevertheless established in the discourse. These results suggest readers encode a narrow set of only those alternatives plausible in the particular discourse. They also indicate that multiple manipulations of linguistic prominence, not just prosody, can lead to consideration of alternatives. PMID:24014934

Despite recent interest in cognitive changes in patients with amyotrophic lateral sclerosis (ALS), investigations of language function looking at the level of word, sentence and discourse processing are relatively scarce. Data were obtained from 26 patients with sporadic ALS and 26 healthy controls matched for age, education, gender, anxiety, depression and executive function performance. Standardized language tasks included confrontation naming, semantic access, and syntactic comprehension. Quantitative production analysis (QPA) was used to analyse connected speech samples of the Cookie Theft picture description task. Results showed that the ALS patients were impaired on standardized measures of grammatical comprehension and action/verb semantics. At the level of discourse, ALS patients were impaired on measures of syntactic complexity and fluency; however, the latter could be better explained by disease related factors. Discriminant analysis revealed that syntactic measures differentiated ALS patients from controls. In conclusion, patients with ALS exhibit deficits in receptive and expressive language on tasks of comprehension and connected speech production, respectively. Our findings suggest that syntactic processing deficits seem to be the predominant feature of language impairment in ALS and that these deficits can be detected by relatively simple language tests.

Scientific literacy is the foundation on which both California's currently adopted science standards and the recommended new standards for science are based (CDE, 2000; NRC, 2011). The Writing for Science Literacy (WSL) curriculum focuses on a series of writing and discussion tasks aimed at increasing students' scientific literacy. These tasks are based on three teaching and learning constructs: thought and language, scaffolding, and meta-cognition. To this end, WSL is focused on incorporating several strategies from the Rhetorical Approach to Reading, Writing, Listening and Speaking to engage students in activities designed to increase their scientific literacy; their ability to both identify an author's claim and evidence and to develop their own arguments based on a claim and evidence. Students participated in scaffolded activities designed to strengthen their written and oral discourse, hone their rhetorical skills and improve their meta-cognition. These activities required students to participate in both writing and discussion tasks to create meaning and build their science content knowledge. Students who participated in the WSL curriculum increased their written and oral fluency and were able to accurately write an evidence-based conclusion all while increasing their conceptual knowledge. This finding implies that a discourse rich curriculum can lead to an increase in scientific knowledge.

The growing numbers of seniors worldwide and the need for support and services that follow from a higher standard of living have led to an increased focus on scarce benefits and limited human resources. At the same time, many western countries have had to make welfare cuts to balance budgets. This has brought the contributions of informal carers to the fore. Thus far, the focus has generally been on the need for the informal carers to receive information and support; to enable them to contribute. The study is designed as an institutional ethnography. The article describes the social processes of informal caregiving and how it interacts with formal caregiving, from the perspective of informal carers. The research question for the study is How do institutional discourses on the work of informal carers influence informal carework? Data for the article comes from qualitative semi-structured interviews with 26 informal carers caring for persons with dementia in Norway, and with 7 administrators working in the allocation divisions of five different municipalities. The results demonstrate how three institutional discourses of informal carers' work influence the allocation divisions' practices and the work of informal carers in caring for their next of kin. The three discourses are categorised as moral and family obligation, shared care and task specificity. The informal carers want to contribute, as they feel a family and moral obligation to their next of kin. In the interaction with the allocation division, they find that the expectation that they will share in the carework and perform specific tasks forces them to perform care within a framework set by the public services. The findings suggest that further research should challenge how services are distributed and allocated rather than focus on how to enable informal carers to fulfil their role better. Because of their moral and family obligation, the informal carers do not have to be forced to perform certain tasks or parts of the shared care. To maintain the informal carers' carework and to fully utilise their contributions, public services would benefit from collaborating with the informal carers to fulfil the total care need of the person with dementia.
How Cognitive Load Influences Speakers' Choice of Referring Expressions.
Vogels, Jorrig; Krahmer, Emiel; Maes, Alfons
2015-08-01
We report on two experiments investigating the effect of an increased cognitive load for speakers on the choice of referring expressions. Speakers produced story continuations to addressees, in which they referred to characters that were either salient or non-salient in the discourse. In Experiment 1, referents that were salient for the speaker were non-salient for the addressee, and vice versa. In Experiment 2, all discourse information was shared between speaker and addressee. Cognitive load was manipulated by the presence or absence of a secondary task for the speaker. The results show that speakers under load are more likely to produce pronouns, at least when referring to less salient referents. We take this finding as evidence that speakers under load have more difficulties taking discourse salience into account, resulting in the use of expressions that are more economical for themselves. © 2014 Cognitive Science Society, Inc.

Interest in inquiry-based science education (IBSE) often pays little heed to the complex power relations that exist within classrooms. A common obstacle to inquiry is that it strongly diverges from current classroom culture and hence, is outside the sphere of teachers' and students' experiences. Teachers and students bring expectations to the classroom that are entrenched in traditional practices and influenced by dynamics of power that exist within all teacher-student relationships. This study, which emerged during a wider study of the use of a Virtual Chemistry Lab in supporting IBSE, explores how classroom discourse constructs and maintains power relations that either stifle or facilitate inquiry-based approaches in two science lessons. Research methods included teacher interviews, student focus groups, video-recorded lessons, and student self-assessments. Findings indicate distinctive features of power inside the classroom that impact on inquiry-based instruction, such as predominant teacher monitoring on task completion over task understanding, lack of student engagement in ownership of scientific ideas, and prevailing norms of what effective teacher questioning is. We discuss implications for IBSE change efforts, highlighting that well-established power relations currently represent an important limiting factor in the capacity of teachers' IBSE implementation.

The article by Goodrich-Hunsaker and Hopkins (2010, this issue) takes up an important place among in the recent contributions on the role of the hippocampus in memory. They evaluate the effect of bilateral damage to the hippocampus on performance by human participants in a virtual 8-arm radial maze. The hippocampal damage appears to be highly selective and nearly complete. Exactly as with selective hippocampal damage in rats, the human participants showed a deficit in accurately choosing rewarded versus never-rewarded arms and a deficit in avoiding reentering recently visited arms. The results are triply significant: (1) They provide good support for the idea that the wealth of neurobiological information, from network to synapse to gene, on spatial memory in the rat may apply as a whole to the human hippocampal memory system; (2) They affirm the utility of human virtual task models of rat spatial memory tasks; (3) They support one interpretation of the dampening of the hippocampal functional MRI (fMRI) blood oxygen level-dependent (BOLD) signal during performance of the virtual radial arm maze observed by Astur et al. (2005).

Discourse Factors Influencing Spatial Descriptions in English and German
NASA Astrophysics Data System (ADS)
Vorwerg, Constanze; Tenbrink, Thora
The ways in which objects are referred to by using spatial language depend on many factors, including the spatial configuration and the discourse context. We present the results of a web experiment in which speakers were asked to either describe where a specified item was located in a picture containing several items, or which item was specified. Furthermore, conditions differed as to whether the first six configurations were specifically simple or specifically complex. Results show that speakers' spatial descriptions are more detailed if the question is where rather than which, mirroring the fact that contrasting the target item from the others in which tasks may not always require an equally detailed spatial description as in where tasks. Furthermore, speakers are influenced by the complexity of initial configurations in intricate ways: on the one hand, individual speakers tend to self-align with respect to their earlier linguistic strategies; however, also a contrast effect could be identified with respect to the usage of combined projective terms.

Early science instruction is important in order to lay a firm basis for learning scientific concepts and scientific thinking. In addition, young children enjoy science. However, science plays only a minor role in the kindergarten curriculum. It has been reported that teachers feel they need to prioritize language and literacy practices over science. In this paper, we investigate whether science lessons might be integrated with learning the language functional for school: academic language. The occurrence of scientific reasoning and sophisticated vocabulary in brief science lessons with 5-year-olds is evaluated. The aim of the study was twofold: first, to explore the nature of kindergarten science discourse without any researcher directions (pre-intervention observation). Second, in a randomized control trial, we evaluated the effect on science discourse of a brief teacher training session focused on academic language awareness. The science lessons focussed on air pressure and mirror reflection. Analyses showed that teachers from the intervention group increased their use of scientific reasoning and of domain-specific academic words in their science discourse, compared to the control group. For the use of general academic words and for lexical diversity, the effect was task-specific: these dependent measures only increased during the air pressure task. Implications of the study include the need to increase teachers' awareness of possibilities to combine early science instruction and academic language learning.

Prior studies of mind wandering find the default network active during mind wandering, but these studies have yielded mixed results concerning the role of cognitive control brain regions during mind wandering. Mind wandering often interferes with reading comprehension, and prior neuroimaging studies of discourse comprehension and strategic reading comprehension have shown that there are at least two networks of brain regions that support strategic discourse comprehension: a domain-general control network and a network of regions supporting coherence-building comprehension processes. The present study was designed to further examine the neural correlates of mind wandering by examining mind wandering during strategic reading comprehension. Participants provided ratings of mind wandering frequency that were used to investigate interactions between the strategy being performed and brain regions whose activation was modulated by wind wandering. The results support prior findings showing that cognitive control regions are at times more active during mind wandering than during a task with low control demands, such as rereading. This result provides an initial examination of the neural correlates of mind wandering during discourse comprehension and shows that the processes being engaged by the primary task need to be considered when studying mind wandering. The results also replicate, in a different learning domain, prior findings of key brain areas associated with different reading strategies. © 2013 Published by Elsevier B.V.

Better dual-task processing in simultaneous interpreters
Strobach, Tilo; Becker, Maxi; Schubert, Torsten; Kühn, Simone
2015-01-01
Simultaneous interpreting (SI) is a highly complex activity and requires the performance and coordination of multiple, simultaneous tasks: analysis and understanding of the discourse in a first language, reformulating linguistic material, storing of intermediate processing steps, and language production in a second language among others. It is, however, an open issue whether persons with experience in SI possess superior skills in coordination of multiple tasks and whether they are able to transfer these skills to lab-based dual-task situations. Within the present study, we set out to explore whether interpreting experience is associated with related higher-order executive functioning in the context of dual-task situations of the Psychological Refractory Period (PRP) type. In this PRP situation, we found faster reactions times in participants with experience in simultaneous interpretation in contrast to control participants without such experience. Thus, simultaneous interpreters possess superior skills in coordination of multiple tasks in lab-based dual-task situations. PMID:26528232

Collaborative teamwork is a common practice in both science and engineering schools and workplaces. This study, using a mixed-methods approach, was designed to identify which team discourse characteristics are correlated with changes in student self-efficacy and achievement. Bandura's self-efficacy theory constitutes the theoretical framework. Seven teams, consisting of first-year engineering students, took the pre- and post-surveys and were video- and audio-recorded during a semester-long Introduction to Engineering Design course. Three instruments were developed: a self-efficacy survey, a team interaction observation protocol, and a team interaction self-report survey. The reliability and validity of these instruments were established. An iterative process of code development and refinement led to the development of thirty-five discourse types, which were grouped under six discourse categories: task-oriented, response-oriented, learning-oriented, support-oriented, challenge-oriented, and disruptive. The results of the quantitative data analysis showed that achievement and gain in self-efficacy were significantly correlated ( r=.55, p<.01). There was also a positive correlation between support-orientated discourse and post self-efficacy scores ( r=.43, p<.05). Negative correlations were observed between disruptive discourse behaviors and post self-efficacy (r=-.48, p<.05). Neither being challenged by peers nor receiving negative feedback revealed significant correlations with student self-efficacy. In addition, no direct correlations between the team discourse characteristics and achievement were found. These findings suggest that collaborative teamwork can lead to achievement to the extent that it supports self-efficacy. They also suggest that interactions such as receiving positive or negative feedback have less impact on self-efficacy than does the overall constructive behavior of the group. The qualitative component of the study, which focused on three case studies, presents how supportive and disruptive interactions occurred during team discourse. Discussion includes recommendations for educators on how to help teams build supportive environments as well as what to look for when forming teams and evaluating student team interactions.

The goal of this study was to determine whether variability in working memory (WM) capacity and cognitive control affects the processing of global discourse congruence and local associations among words when participants listened to short discourse passages. The final, critical word of each passage was either associated or unassociated with a preceding prime word (e.g., “He was not prepared for the fame and fortune/praise”). These critical words were also either congruent or incongruent with respect to the preceding discourse context [e.g., a context in which a prestigious prize was won (congruent) or in which the protagonist had been arrested (incongruent)]. We used multiple regression to assess the unique contribution of suppression ability (our measure of cognitive control) and WM capacity on the amplitude of individual N400 effects of congruence and association. Our measure of suppression ability did not predict the size of the N400 effects of association or congruence. However, as expected, the results showed that high WM capacity individuals were less sensitive to the presence of lexical associations (showed smaller N400 association effects). Furthermore, differences in WM capacity were related to differences in the topographic distribution of the N400 effects of discourse congruence. The topographic differences in the global congruence effects indicate differences in the underlying neural generators of the N400 effects, as a function of WM. This suggests additional, or at a minimum, distinct, processing on the part of higher capacity individuals when tasked with integrating incoming words into the developing discourse representation.

This study reveals that the entry into World War I in 1917 indexed the decisive transition to the modern period in American political consciousness, ushering in new objects of political discourse, a more rapid pace of change of those objects, and a fundamental reframing of the main tasks of governance. We develop a strategy for identifying meaningful categories in textual corpora that span long historic durées, where terms, concepts, and language use changes. Our approach is able to account for the fluidity of discursive categories over time, and to analyze their continuity by identifying the discursive stream as the object of interest. PMID:26261302

The intraprofessional discourse about economical aspects in nursing from an ethical point of view has not taken place yet. To cope with the increasing restriction of resources, some preconditions have to be met: It is necessary to communicate issues in rationalizing and rationing in nursing openly. Person-oriented criteria in the nursing process indicate a high level of competence and user-oriented quality in nursing care. But nursing professionals do not decide in favor or against resources to perform this task on a high or poor quality level. Democratic decision-making on providing nursing services depends on a continuous societal discourse about allocation criteria.

For more than 30 years, the term "palliative care" has been used. From the outset, the term has undergone a series of transformations in its definitions and consequently in its tasks and goals. There remains a lack of consensus on a definition. The aim of this article is to analyse the definitions of palliative care in the specialist literature and to identify the key elements of palliative care using discourse analysis: a qualitative methodology. The literature search focused on definitions of the term 'palliative medicine' and 'palliative care' in the World Wide Web and medical reference books in English and German. A total of 37 English and 26 German definitions were identified and analysed. Our study confirmed the lack of a consistent meaning concerning the investigated terms, reflecting on-going discussion about the nature of the field among palliative care practitioners. Several common key elements were identified. Four main categories emerged from the discourse analysis of the definition of palliative care: target groups, structure, tasks and expertise. In addition, the theoretical principles and goals of palliative care were discussed and found to be key elements, with relief and prevention of suffering and improvement of quality of life as main goals. The identified key elements can contribute to the definition of the concept 'palliative care'. Our study confirms the importance of semantic and ethical influences on palliative care that should be considered in future research on semantics in different languages.

We investigated direct and indirect effects of component skills on writing (DIEW) using data from 193 children in Grade 1. In this model, working memory was hypothesized to be a foundational cognitive ability for language and cognitive skills as well as transcription skills, which, in turn, contribute to writing. Foundational oral language skills (vocabulary and grammatical knowledge) and higher-order cognitive skills (inference and theory of mind) were hypothesized to be component skills of text generation (i.e., discourse-level oral language). Results from structural equation modeling largely supported a complete mediation model among four variations of the DIEW model. Discourse-level oral language, spelling, and handwriting fluency completely mediated the relations of higher-order cognitive skills, foundational oral language, and working memory to writing. Moreover, language and cognitive skills had both direct and indirect relations to discourse-level oral language. Total effects, including direct and indirect effects, were substantial for discourse-level oral language (.46), working memory (.43), and spelling (.37), followed by vocabulary (.19), handwriting (.17), theory of mind (.12), inference (.10), and grammatical knowledge (.10). The model explained approximately 67% of variance in writing quality. These results indicate that multiple language and cognitive skills make direct and indirect contributions, and it is important to consider both direct and indirect pathways of influences when considering skills that are important to writing.

The rules of the game: properties of a database of expository language samples.
Heilmann, John; Malone, Thomas O
2014-10-01
The authors created a database of expository oral language samples with the aims of describing the nature of students' expository discourse and providing benchmark data for typically developing preteen and teenage students. Using a favorite game or sport protocol, language samples were collected from 235 typically developing students in Grades 5, 6, 7, and 9. Twelve language measures were summarized from this database and analyses were completed to test for differences across ages and topics. To determine whether distinct dimensions of oral language could be captured with language measures from these expository samples, a factor analysis was completed. Modest differences were observed in language measures across ages and topics. The language measures were effectively classified into four distinct dimensions: syntactic complexity, expository content, discourse difficulties, and lexical diversity. Analysis of expository data provides a functional and curriculum-based assessment that has the potential to allow clinicians to document multiple dimensions of children's expressive language skills. Further development and testing of the database will establish the feasibility of using it to compare individual students' expository discourse skills to those of their typically developing peers.

Long-term Recovery in Stroke Accompanied by Aphasia: A Reconsideration.
Holland, Audrey; Fromm, Davida; Forbes, Margaret; MacWhinney, Brian
2017-01-01
This work focuses on the twenty-six individuals who provided data to AphasiaBank on at least two occasions, with initial testing between 6 months and 5.8 years post-onset of aphasia. The data are archival in nature and were collected from the extensive database of aphasic discourse in AphasiaBank. The aim is to furnish data on the nature of long-term changes in both the impairment of aphasia as measured by the Western Aphasia Battery-Revised (WAB-R) and its expression in spoken discourse. AphasiaBank's demographic database was searched to discover all individuals who were tested twice at an interval of at least a year with either: 1) the AphasiaBank protocol; or 2) the AphasiaBank protocol at first testing, and the Famous People Protocol (FPP) at second testing. The Famous People Protocol is a measure developed to assess the communication strategies of individuals whose spoken language limitations preclude full participation in the AphasiaBank protocol. The 26 people with aphasia (PWA) who were identified had completed formal speech therapy before being seen for AphasiaBank. However, all were participants in aphasia centers where at least three hours of planned activities were available, in most cases, twice weekly. WAB-R Aphasia Quotient scores (AQ) were examined, and in those cases where AQ scores improved, changes were assessed on a number of measures from the AphasiaBank discourse protocol. Sixteen individuals demonstrated improved WAB-R AQ scores, defined as positive AQ change scores greater than the WAB-R AQ standard error of the mean (WAB-SEM); seven maintained their original WAB quotients, defined as AQ change scores that were not greater than the WAB-SEM; and the final three showed negative WAB-R change scores, defined as a negative WAB-R AQ change score greater than the WAB-SEM. Concurrent changes on several AphasiaBank tasks were also found, suggesting that the WAB-R improvements were noted in more natural discourse as well. These data are surprising, since conventional wisdom suggests that spontaneous improvement in language is unlikely to occur beyond one year. Long-term improvement or maintenance of early test scores, such as that shown here, has seldom been demonstrated in the absence of formal treatment. Speculations about why these PWA improved, maintained or declined in their scores are considered.
Responses on a lateralized lexical decision task relate to both reading times and comprehension.
Michael, Mary
2009-12-01
Research over the last few years has shown that the dominance of the left hemisphere in language processing is less complete than previously thought [Beeman, M. (1993). Semantic processing in the right hemisphere may contribute to drawing inferences from discourse. Brain and Language, 44, 80-120; Faust, M., & Chiarello, C. (1998). Sentence context and lexical ambiguity resolution by the two hemispheres. Neuropsychologia, 36(9), 827-835; Weems, S. A., & Zaidel, E. (2004). The relationship between reading ability and lateralized lexical decision. Brain and Cognition, 55(3), 507-515]. Engaging the right brain in language processing is required for processing speaker/writer intention, particularly in those subtle interpretive processes that help in deciphering humor, irony, and emotional inference. In two experiments employing a divided field or lateralized lexical decision task (LLDT), accuracy and reaction times (RTs) were related to reading times and comprehension on sentence reading. Differences seen in RTs and error rates by visual fields were found to relate to performance. Smaller differences in performance between fields tended to be related to better performance on the LLDT in both experiments and, in Experiment 1, to reading measures. Readers who can exploit both hemispheres for language processing equally appear to be at an advantage in lexical access and possibly also in reading performance.

Language acquisition: hesitations in the question/answer dialogic pair.
Chacon, Lourenço; Villega, Cristyane de Camargo Sampaio
2015-01-01
(1) To verify the existence (or not) of hesitation marks in the beginning of utterances in children's discourse; and (2) to determine to what extent the presence/absence of these marks could be explained by retrievable facts in the production conditions of their discourses. Interview situations with four children aged 5-6 years attending Kindergarten level II in a public preschool at the time of the data collection were analyzed. The interviews were recorded on audio and video, inside a soundproof booth, with high fidelity equipment. Afterwards, the recordings were transcribed by six transcribers that were specially trained for this task. Transcription rules that prioritized the analyses of hesitations were used. For the analysis of retrievable facts in the production conditions of children's discourse, the dialogic pair question-answer was adopted. A correlation between presence/absence of hesitation in the beginning of utterances in children and type of question (open/closed) made by the collocutor was observed. When the question was closed ended, the utterances were preferably initiated without hesitation marks, and when the question was open ended, the utterances were preferably initiated with hesitation marks. The presence/absence of hesitation marks in the beginning of utterances in children was found to be dependent on the production conditions of their discourses.

The challenge of attracting and retaining the next generation of teachers who are skilled and committed to meeting the growing demands of the profession is of increasing concern to researchers and policy makers, particularly since 45--50% of beginning teachers leave the profession within five years (Ingersoll & Smith, 2003). Reasons for such attrition include compensation, status and working conditions; however, there is growing evidence that a critical factor in new teacher retention hinges on teachers' ability to accomplish the difficult task of forming a workable professional identity in the midst of competing discourses about teaching (Alsup, 2006; Britzman, 2003). There is little research on professional identity development among those beginning teachers at highest risk for attrition (secondary math and science teachers, and those with strong academic backgrounds). This study explores the professional identity development of early-career math and science teachers who are part of the Knowles Science Teaching Foundation's (KSTF) teaching fellowship program, an external support network that aims to address many of the issues leading to high attrition among this particular population of teachers. Using narrative research methods, I examine three case studies of beginning teachers, exploring how they construct professional identity in relation to various discourse communities and negotiate tensions across multiple discourses. The cases identify both dominant discourses and counter-discourses that the teachers draw upon for important identity development resources. They also demonstrate that the way a teacher manages tensions across competing discourses is important to how well one can negotiate a workable professional identity. In particular, they emphasize the importance of engaging in borderland discourses (Gee, 1996) as a way of taking agency in one's own identity development as well as in transforming one's discourse communities. These cases shed light on how these beginning teachers work to negotiate a workable professional identity that may sustain them in a teaching career. In addition, they help us understand how a support network like KSTF can serve as a resource for helping new teachers construct professional identities, therefore addressing some of the issues that may lead to attrition among this population of new teachers.
Enhancing ASTRO101 Student Engagement Using Student-Created ScienceSKETCHES

Slater, Timothy F.; Slater, Stephanie
2016-01-01
As astronomy teaching faculty are changing their teaching strategies from those less desirable approaches that allow students to passively listen to professor-centered, information-lectures to more desirable, active-student engagement classrooms characterized by active learning, ASTRO 101 professors are looking for more ways to help students learn to participate in authentic scientific practices. This is consistent with notion advocated by the NRC that students should practice scientific thinking, scientific discourse, and scientific practices while learning science. Noticing that much informal scientific discussion is mediated by sketches—such as those occasionally lively discussions held after hours during scientific conferences—scholars at the CAPER Center for Astronomy & Physics Education Research have been piloting a series of active learning tasks where students are challenged to create scientific drawings to illustrate their understanding of astronomical phenomena or structures. Known informally as ScienceSKETCHES, examples of these tasks challenge students to illustrate: the spectral curve differences between high and low mass stars; the differences among galaxy shapes; the distribution of stars for the Andromeda Galaxy in terms of luminosity versus temperature; old and young planetary surfaces; or the relationships between distances and speeds of orbiting objects. Although our initial testing has focused on predominately on paper and pencil tasks, with the occasional cell phone picture of a ScienceSKETCH being texted to the professor, the electronic-based teaching world is nearly ready to support these sorts of drawing tasks. Already, the ability to complete and submit scientific sketches is becoming commonplace across electronic learning platforms, including shared white-boarding in many desktop videoconferencing systems, and handheld device learning systems for interactive classrooms, like those from Learning Catalytics, among many others. Our initial results suggest that this strategy is worthwhile line of research and development for a wide range of astronomy education researchers and curriculum developers.

This study examined interrelations among different types of parental emotion socialization behaviors in 88 mothers and 76 fathers (co-residing with participating mothers) of 8-year-old children. Parents completed questionnaires assessing emotion socialization behaviors, emotion-related attitudes, and their children’s social functioning. An observed parent-child emotion discourse task and a child social-problem solving interview were also performed. Parent gender differences and concordance within couples in emotion socialization behaviors were identified for some but not all behaviors. Fathers’ reactions to child emotion, family expressiveness, and fathers’ emotion coaching during discussion cohered, and a model was supported in which the commonality among these behaviors was predicted by fathers’ emotion-coaching attitudes, and was associated with children’s social competence. A cohesive structure for the emotion socialization construct was less clear for mothers, although attitudes predicted all three types of emotion socialization behavior (reactions, expressiveness, and coaching). Implications for developmental theory and for parent-focused interventions are discussed. PMID:21532915
The epistemological significance of possession entering the DSM.
Stephenson, Craig
2015-09-01
The discourse of the American Psychiatric Association's DSM reflects the inherently dialogic or contradictory nature of its stated mandate to demonstrate both 'nosological completeness' and cultural 'inclusiveness'. Psychiatry employs the dialogic discourse of the DSM in a one-sided, positivistic manner by identifying what it considers universal mental disease entities stripped of their cultural context. In 1992 the editors of the Diagnostic and Statistical Manual of Mental Disorders proposed to introduce possession into their revisions. A survey of the discussions about introducing 'possession' as a dissociative disorder to be listed in the DSM-IV indicates a missed epistemological break. Subsequently the editors of the DSM-5 politically 'recuperated' possession into its official discourse, without acknowledging the anarchic challenges that possession presents to psychiatry as a cultural practice. © The Author(s) 2015.
Drawing the line between constituent structure and coherence relations in visual narratives.
Cohn, Neil; Bender, Patrick
2017-02-01
Theories of visual narrative understanding have often focused on the changes in meaning across a sequence, like shifts in characters, spatial location, and causation, as cues for breaks in the structure of a discourse. In contrast, the theory of visual narrative grammar posits that hierarchic "grammatical" structures operate at the discourse level using categorical roles for images, which may or may not co-occur with shifts in coherence. We therefore examined the relationship between narrative structure and coherence shifts in the segmentation of visual narrative sequences using a "segmentation task" where participants drew lines between images in order to divide them into subepisodes. We used regressions to analyze the influence of the expected constituent structure boundary, narrative categories, and semantic coherence relationships on the segmentation of visual narrative sequences. Narrative categories were a stronger predictor of segmentation than linear coherence relationships between panels, though both influenced participants' divisions. Altogether, these results support the theory that meaningful sequential images use a narrative grammar that extends above and beyond linear semantic shifts between discourse units.

Three mathematics teachers in secondary education were confronted with the question of how to encourage students to discuss their work with each other in the daily practice of their mathematical lessons. In response to this question the teachers devised three different approaches to encourage student discourse. One of the teachers chose to experiment with another setting to perform mathematical tasks that involved students working together on a group test. The second teacher experimented with a new kind of help when students were working on their maths tasks and asked for assistance. The third created a new setting in which the teacher (temporarily) did not provide mathematical hints and the students had to solve their own problems. The three teachers were very motivated, but they all had difficulties in not giving explanations themselves when supporting their students in their collaborative mathematical learning. They found that temporarily diminishing their product help stimulated discussion between students. It also became clear that the process of teacher reflection and follow-up discussions with the researcher/observers promoted changes of practice.

Uncertainty is ubiquitous in life, and learning is an activity particularly likely to be fraught with uncertainty. Previous research suggests that students and teachers struggle in their attempts to manage the psychological experience of uncertainty and that students often fail to experience uncertainty when uncertainty may be warranted. Yet, few educational researchers have explicitly and systematically observed what students do, their behaviors and strategies, as they attempt to manage the uncertainty they experience during academic tasks. In this study I investigated how students in one fifth grade class managed uncertainty they experienced while engaged in collaborative robotics engineering projects, focusing particularly on how uncertainty management was influenced by task structure and students' interactions with their peer collaborators. The study was initiated at the beginning of instruction related to robotics engineering and preceded through the completion of several long-term collaborative robotics projects, one of which was a design project. I relied primarily on naturalistic observation of group sessions, semi-structured interviews, and collection of artifacts. My data analysis was inductive and interpretive, using qualitative discourse analysis techniques and methods of grounded theory. Three theoretical frameworks influenced the conception and design of this study: community of practice, distributed cognition, and complex adaptive systems theory. Uncertainty was a pervasive experience for the students collaborating in this instructional context. Students experienced uncertainty related to the project activity and uncertainty related to the social system as they collaborated to fulfill the requirements of their robotics engineering projects. They managed their uncertainty through a diverse set of tactics for reducing, ignoring, maintaining, and increasing uncertainty. Students experienced uncertainty from more different sources and used more and different types of uncertainty management strategies in the less structured task setting than in the more structured task setting. Peer interaction was influential because students relied on supportive social response to enact most of their uncertainty management strategies. When students could not garner socially supportive response from their peers, their options for managing uncertainty were greatly reduced.
The development of discourse referencing in Cantonese-speaking children.
Wong, Anita M Y; Johnston, Judith R
2004-08-01
The ability to make clear reference in connected discourse was examined in children learning Cantonese, a Chinese language where noun phrase constituents, whatever their grammatical role, are omissible from sentences under discourse conditions that are not well-understood. Forty-three typically developing children aged 3 ; 0, 5 ; 0, 7 ; 0 and 12 ; 0 told 16 stories based on picture sequences. A panel of adult native Cantonese speakers was asked to judge the referential adequacy of each child's stories by identifying the character the child was talking about in 32 targeted referential acts. The targeted acts were of three sorts: MAINTENANCE of a known character, INTRODUCTION of a second new character, and REINTRODUCTION of a known character. Reference was judged to be adequate when 3 out of 4 'listeners' could successfully identify the character. Children's referential expressions were most adequate for Maintenance, less adequate for Introduction, and least adequate for Reintroduction. The twelve- and seven-year-olds approached ceiling on all three functions. The five-year-olds scored poorly on Reintroduction, and the three-year-olds failed both Introduction and Reintroduction, despite knowledge of at least one of the possible linguistic forms required for these acts as evidenced in a sentence imitation task. Viewed within the framework of Levelt's (1989) discourse model, the data improve our understanding of the developmental period during which children learn to make appropriate presuppositions about the listener's knowledge and attentional states.

Engineering design challenges offer important opportunities for students to learn science and engineering knowledge and practices. This study examines how students' engineering notebooks across four units of the curriculum Engineering is Elementary (EiE) support student work during design challenges. Through educational ethnography and discourse analysis, transcripts of student talk and action were created and coded around the uses of notebooks in the accomplishment of engineering tasks. Our coding process identified two broad categories of roles of the notebooks: they scaffold student activity and support epistemic practices of engineering. The study showed the importance of prompts to engage students in effective uses of writing, the roles the notebook assumes in the students' small groups, and the ways design challenges motivate children to write and communicate.

Doing and learning science are social activities that require certain language, activities, and values. Both constitute what Gee (2005) calls Discourses. The language of learning science varies with the learning context (Lemke, 2001,1990). Science for All Americans (AAAS, 1990) and Inquiry and the National Science Education Standards (NRC, 2000) endorse inquiry science learning. In the United States, most science learning is teacher-centered; inquiry science learning is rare (NRC, 2000). This study focused on 12 high school students from two suburban high schools, their three faculty mentors, and two engineering mentors during an extracurricular robotics activity with FIRST Robotics Competition (FRC). FRC employed student-centered inquiry focus to teach science principles integrating technology. Research questions were (a) How do science teachers and their students enact Discourses as they teach and learn science? and (b) How does the pedagogical approach of a learning activity facilitate the Discourses that are enacted by students and teachers as they learn and teach science? Using Critical Discourse Analysis (CDA), the study examined participants' language during robotic activities to determine how language used in learning science shaped the learning and vice versa. Data sources included videorecordings of participant language and semi-structured interviews with study participants. Transcribed recordings were coded initially using Gee's (2005) linguistic Building Tasks as a priori codes. CDA was applied to code transcripts, to construct Discourses enacted by the participants, and to determine how context facilitated their enactment. Findings indicated that, for the students, FRC facilitated elements of Science Discourse. Wild About Robotics (W.A.R.) team became, through FRC, part of a community similar to scientists' community that promoted knowledge and sound practices, disseminated information, supported research and development and encouraged interaction of its members. The public school science classroom in the U.S. is inimical to inquiry learning because of practices and policies associated with the epistemological stance that spawned the standards and/or testing movement and No Child Left Behind (Baez & Boyles, 2009). The findings of this study provided concrete ideas to accommodate the recommendations by NRC (1996) and NSES (2000) for creating contexts that might lead to inquiry science learning for meaningful student engagement.

Purpose To examine children’s comprehension of verb phrase (VP) ellipsis constructions in light of their automatic, online structural processing abilities and conscious, metalinguistic reflective skill. Method Forty-two children ages 5 through 12 years listened to VP ellipsis constructions involving the strict/sloppy ambiguity (e.g., “The janitor untangled himself from the rope and the fireman in the elementary school did too after the accident.”) in which the ellipsis phrase (“did too”) had 2 interpretations: (a) strict (“untangled the janitor”) and (b) sloppy (“untangled the fireman”). We examined these sentences at a normal speech rate with an online cross-modal picture priming task (n = 14) and an offline sentence–picture matching task (n = 11). Both tasks were also given with slowed speech input (n = 17). Results Children showed priming for both the strict and sloppy interpretations at a normal speech rate but only for the strict interpretation with slowed input. Offline, children displayed an adultlike preference for the sloppy interpretation with normal-rate input but a divergent pattern with slowed speech. Conclusions Our results suggest that children and adults rely on a hybrid syntax-discourse model for the online comprehension and offline interpretation of VP ellipsis constructions. This model incorporates a temporally sensitive syntactic process of VP reconstruction (disrupted with slow input) and a temporally protracted discourse effect attributed to parallelism (preserved with slow input).

Stable aesthetic standards delusion: changing 'artistic quality' by elaboration.
Carbon, Claus-Christian; Hesslinger, Vera M
2014-01-01
The present study challenges the notion that judgments of artistic quality are based on stable aesthetic standards. We propose that such standards are a delusion and that judgments of artistic quality are the combined result of exposure, elaboration, and discourse. We ran two experiments using elaboration tasks based on the repeated evaluation technique in which different versions of the Mona Lisa had to be elaborated deeply. During the initial task either the version known from the Louvre or an alternative version owned by the Prado was elaborated; during the second task both versions were elaborated in a comparative fashion. After both tasks multiple blends of the two versions had to be evaluated concerning several aesthetic key variables. Judgments of artistic quality of the blends were significantly different depending on the initially elaborated version of the Mona Lisa, indicating experience-based aesthetic processing, which contradicts the notion of stable aesthetic standards.
Power in clinical teachers' discourses of a curriculum-in-action. Critical discourse analysis.
Graham, Jennifer; Dornan, Tim
2013-12-01
"Curricula-in-action" generally differ from "official" curricula. That is particularly true of clerkship curricula because the practising doctors who supervise medical students' clinical activities are only secondarily educators. Clerkship education is evaluated, however, according to benchmarks set by official curricula. As a result, clerkship evaluations are important points of contact between clinical teachers and medical schools. We reasoned that an evaluation instrument is part of a medical school's official curriculum discourse and clinical teachers' reactions to it are a discourse of curriculum-in-action. We set out to answer the questions: What are clinical teachers' discourses of curriculum-in-action and how do they relate to an official curriculum discourse? Nineteen clerkship placement leads from two hospitals contributing to a single undergraduate medical programme participated. The evaluation instrument was the Manchester Clinical Placement Index, for which validity evidence has been published. Respondents were asked to say how they would react to junior students giving their placements low or high scores for each of 12 items from the Index. After transcription, we conducted a critical discourse analysis (CDA) of their audio-recorded answers. We purposefully selected the six items that elicited the widest spectrum of responses for analysis because quantity of material can compromise the quality of CDA. A dominant discourse of curriculum-in-action defined how teachers should "really" teach and junior students should learn. It deconstructed the need for teachers to be present when students performed clinical tasks because teachers' role was to give critical feedback on case presentations that were coincidental to clinical care. It positioned students at the bottom of a power hierarchy so they had to "struggle" to be taught. It placed respondents in a powerful position relative to "the hospital" and "the university", though there were tensions between respondents, patients, and nurses. Respondents dismissed criticism that was invalid according to their curriculum-in-action, which included most items in an evaluation instrument. There was a contrasting, non-dominant discourse of responding reflectively to feedback, which generated realistic ways of improving students' learning. The strength of respondents' emotions shows just how committed doctors are to students' learning. The strength of their expressions of power, however, explains why many of them teach in their own way rather than according to official curricula. Changes to clinical curricula, our findings suggest, will not be successful unless they are carefully negotiated with practising doctors.
The modality effect of ego depletion: Auditory task modality reduces ego depletion.
Li, Qiong; Wang, Zhenhong
2016-08-01
An initial act of self-control that impairs subsequent acts of self-control is called ego depletion. The ego depletion phenomenon has been observed consistently. The modality effect refers to the effect of the presentation modality on the processing of stimuli. The modality effect was also robustly found in a large body of research. However, no study to date has examined the modality effects of ego depletion. This issue was addressed in the current study. In Experiment 1, after all participants completed a handgrip task, one group's participants completed a visual attention regulation task and the other group's participants completed an auditory attention regulation task, and then all participants again completed a handgrip task. The ego depletion phenomenon was observed in both the visual and the auditory attention regulation task. Moreover, participants who completed the visual task performed worse on the handgrip task than participants who completed the auditory task, which indicated that there was high ego depletion in the visual task condition. In Experiment 2, participants completed an initial task that either did or did not deplete self-control resources, and then they completed a second visual or auditory attention control task. The results indicated that depleted participants performed better on the auditory attention control task than the visual attention control task. These findings suggest that altering task modality may reduce ego depletion. © 2016 Scandinavian Psychological Associations and John Wiley & Sons Ltd.

2010-01-01
Science literacy leading to fuller and informed participation in the public debate about science, technology, society, and environmental (STSE) issues that produce justified decisions and sustainable actions is the shared and central goal of the Pacific CRYSTAL Project. There is broad agreement by science education researchers that learners need to be able to construct and interpret specific scientific discourses and texts to be literate in science. We view these capabilities as components in the fundamental sense of science literacy and as interactive and synergetic to the derived sense of science literacy, which refers to having general knowledge about concepts, principles, and methods of science. This article reports on preliminary findings from Years 1, 2, and 3 of the 5-year Pacific CRYSTAL project that aims to identify, develop, and embed explicit literacy instruction in science programs to achieve both senses of science literacy. A community-based, opportunistic, engineering research and development approach has been utilized to identify problems and concerns and to design instructional solutions for teaching middle school (Grades 6, 7, and 8) science. Initial data indicate (a) opportunities in programs for embedding literacy instruction and tasks; (b) difficulties generalist teachers have with new science curricula; (c) difficulties specialist science teachers have with literacy activities, strategies, genre, and writing-to-learn science tasks; and (d) potential literacy activities (vocabulary, reading comprehension, visual literacy, genre, and writing tasks) for middle school science. Preinstruction student assessments indicate a range of challenges in achieving effective learning in science and the need for extensive teacher support to achieve the project’s goals. Postinstructional assessments indicate positive changes in students’ ability to perform target reading and writing tasks. Qualitative data indicate teachers’ desire for external direction and the need for researchers to expand the literacy framework to include oral discourse. A case study of teachers’ use of a specific literacy task and its influence on students revealed indications of robustness and effectiveness. Experiences revealed procedural difficulties and insights regarding community-based research and development approaches.

Background In recent years, biological event extraction has emerged as a key natural language processing task, aiming to address the information overload problem in accessing the molecular biology literature. The BioNLP shared task competitions have contributed to this recent interest considerably. The first competition (BioNLP'09) focused on extracting biological events from Medline abstracts from a narrow domain, while the theme of the latest competition (BioNLP-ST'11) was generalization and a wider range of text types, event types, and subject domains were considered. We view event extraction as a building block in larger discourse interpretation and propose a two-phase, linguistically-grounded, rule-based methodology. In the first phase, a general, underspecified semantic interpretation is composed from syntactic dependency relations in a bottom-up manner. The notion of embedding underpins this phase and it is informed by a trigger dictionary and argument identification rules. Coreference resolution is also performed at this step, allowing extraction of inter-sentential relations. The second phase is concerned with constraining the resulting semantic interpretation by shared task specifications. We evaluated our general methodology on core biological event extraction and speculation/negation tasks in three main tracks of BioNLP-ST'11 (GENIA, EPI, and ID). Results We achieved competitive results in GENIA and ID tracks, while our results in the EPI track leave room for improvement. One notable feature of our system is that its performance across abstracts and articles bodies is stable. Coreference resolution results in minor improvement in system performance. Due to our interest in discourse-level elements, such as speculation/negation and coreference, we provide a more detailed analysis of our system performance in these subtasks. Conclusions The results demonstrate the viability of a robust, linguistically-oriented methodology, which clearly distinguishes general semantic interpretation from shared task specific aspects, for biological event extraction. Our error analysis pinpoints some shortcomings, which we plan to address in future work within our incremental system development methodology. PMID:22759461
The importance of source and cue type in time-based everyday prospective memory.
Oates, Joyce M; Peynircioğlu, Zehra F
2014-01-01
We examined the effects of the source of a prospective memory task (provided or generated) and the type of cue (specific or general) triggering that task in everyday settings. Participants were asked to complete both generated and experimenter-provided tasks and to send a text message when each task was completed. The cue/context for the to-be-completed tasks was either a specific time or a general deadline (time-based cue), and the cue/context for the texting task was the completion of the task itself (activity-based cue). Although generated tasks were completed more often, generated cues/contexts were no more effective than provided ones in triggering the intention. Furthermore, generated tasks were completed more often when the cue/context comprised a specific time, whereas provided tasks were completed more often when the cue/context comprised a general deadline. However, texting was unaffected by the source of the cue/context. Finally, emotion modulated the effects. Results are discussed within a process-driven framework.
Dynamics of Cooperation in a Task Completion Social Dilemma
Passino, Kevin M.
2017-01-01
We study the situation where the members of a community have the choice to participate in the completion of a common task. The process of completing the task involves only costs and no benefits to the individuals that participate in this process. However, completing the task results in changes that significantly benefit the community and that exceed the participation efforts. A task completion social dilemma arises when the short-term participation costs dissipate any interest in the community members to contribute to the task completion process and therefore to obtain the benefits that result from completing the task. In this work, we model the task completion problem using a dynamical system that characterizes the participation dynamics in the community and the task completion process. We show how this model naturally allows for the incorporation of several mechanisms that facilitate the emergence of cooperation and that have been studied in previous research on social dilemmas, including communication across a network, and indirect reciprocity through relative reputation. We provide mathematical analyses and computer simulations to study the qualitative properties of the participation dynamics in the community for different scenarios. PMID:28125721

Elementary science education: Dilemmas facing preservice teachers
NASA Astrophysics Data System (ADS)
Sullivan, Sherry Elaine
Prospective teachers are involved in a process of induction into a culture of teaching that has rules, or codes of conduct for engaging in teaching practice. This same culture of teaching exists within a larger culture of schooling that also has values and norms for behaviors, that over time have become institutionalized. Teacher educators are faced with the challenging task of preparing preservice teachers to resolve dilemmas that arise from conflicts between the pressure to adopt traditional teaching practices of schooling, or to adopt inquiry-based teaching practices from their university methods classes. One task for researchers in teacher education is to define with greater precision what factors within the culture of schooling hinder or facilitate implementation of inquiry-based methods of science teaching in schools. That task is the focus of this study. A qualitative study was undertaken using a naturalistic research paradigm introduced by Lincoln and Guba in 1985. Participant observation, interviews, discourse analysis of videotapes of lessons from the methods classroom and written artifacts produced by prospective teachers during the semester formed the basis of a grounded theory based on inductive analysis and emergent design. Unstructured interviews were used to negotiate outcomes with participants. Brief case reports of key participants were also written. This study identified three factors that facilitated or hindered the prospective teachers in this research success in implementing inquiry-based science teaching in their field placement classrooms: (a) the culture of teaching/teacher role-socialization, (b) the culture of schooling and its resistance to change, and (c) the culture of teacher education, especially in regards to grades and academic standing. Some recommendations for overcoming these persistent obstacles to best practice in elementary science teaching include: (a) preparing prospective teachers to understand and cope with change processes, (b) to understand the nature of teaching and schooling, and (c) to understand the nature of teacher education itself through explicit discourse about these topics. In addition, development of greater partnerships among university faculty and schools though Partnership School models and other community-building efforts can afford prospective teachers more opportunities to enter the discourse; perhaps even as change agents.

The main objective of this case study was to understand the construction of care in the Homecare Program for Bedridden Patients (PADA) of a basic health unit (UBS) in Porto Alegre, RS. Data were obtained from 13 caretaker groups in the UBS, and participating observation recorded in field diary in the patient's homes. An analysis of the discourse practices was performed inspired in Foucault's discourse concepts speeches and in studies on ethics and self-care. In the groups, the caretaker occupied a space that we metaphorically called the Delphic Oracle, a place for acceptance, listening and support. Hearing the dialogues that took place between the team and the caretakers made us face the contradiction present in the institutional discourse, which both stimulates self-care, and imposes rules, duties, tasks. Care as a citizenship right opposite to care as submission and subjugation created tension inside the group several times. Foucault's notion of care comprises a synthesis of the exercise of a person over his- or herself, making him or her better as a human being and, at the same time, capacitating him or her to become a better citizen.

Empirical analysis of secondary biology classrooms revealed that, on average, 68% of teaching time in Germany revolved around processing tasks. Quality of instruction can thus be assessed by analyzing the quality of tasks used in classroom discourse. This quasi-experimental study analyzed how teachers used tasks in 38 videotaped biology lessons pertaining to the topic 'blood and circulatory system'. Two fundamental characteristics used to analyze tasks include: (1) required cognitive level of processing (e.g. low level information processing: repetiition, summary, define, classify and high level information processing: interpret-analyze data, formulate hypothesis, etc.) and (2) complexity of task content (e.g. if tasks require use of factual, linking or concept level content). Additionally, students' cognitive knowledge structure about the topic 'blood and circulatory system' was measured using student-drawn concept maps (N = 970 students). Finally, linear multilevel models were created with high-level cognitive processing tasks and higher content complexity tasks as class-level predictors and students' prior knowledge, students' interest in biology, and students' interest in biology activities as control covariates. Results showed a positive influence of high-level cognitive processing tasks (β = 0.07; p < .01) on students' cognitive knowledge structure. However, there was no observed effect of higher content complexity tasks on students' cognitive knowledge structure. Presented findings encourage the use of high-level cognitive processing tasks in biology instruction.
Is Mandarin Chinese a Truth-Based Language? Rejecting Responses to Negative Assertions and Questions
Li, Feifei; González-Fuente, Santiago; Prieto, Pilar; Espinal, M.Teresa
2016-01-01
This paper addresses the central question of whether Mandarin Chinese (MC) is a canonical truth-based language, a language that is expected to express the speaker's disagreement to a negative proposition by means of a negative particle followed by a positive sentence. Eight native speakers of MC participated in an oral Discourse Completion Task that elicited rejecting responses to negative assertions/questions and broad focus statements (control condition). Results show that MC speakers convey reject by relying on a combination of lexico-syntactic strategies (e.g., negative particles such as bù, méi(yǒu), and positive sentences) together with prosodic (e.g., mean pitch) and gestural strategies (mainly, the use of head nods). Importantly, the use of a negative particle, which was the expected outcome in truth-based languages, only appeared in 52% of the rejecting answers. This system puts into question the macroparametric division between truth-based and polarity-based languages and calls for a more general view of the instantiation of a reject speech act that integrates lexical and syntactic strategies with prosodic and gestural strategies.

Science education reforms of the last two decades have focused on raising the bar for ALL students which includes students with mild to moderate disabilities. Formative assessment can be used to assess the progress of these students to inquire, understand scientific concepts, reason scientifically, make decisions, and communicate effectively in science. The purpose of this study is to examine the use of science journals as a formative assessment in a guided inquiry unit of study for students with learning disabilities. Two normally achieving students (NA) and five students with learning disabilities (SLD) participated in a study of mammals that utilized journals to record the development of student knowledge through the course of study. Students were interviewed after the lessons were complete using the same prompts required in the journals. Themes were developed from the student writings and their verbal discourse using Grounded Theory. Journals and verbal discourse were rated following the themes of Knowledge Telling (KT) and Knowledge Transformation (KTR). Concept maps were developed for the Pre and Post test lessons (written and verbal discourses) by the raters in an attempt to further explain the knowledge that the students conveyed. The results of this study suggest that SLD are able to demonstrate knowledge about mammals better through verbal discourse than written discourse. While the NA students wrote more and used more technical discourse than did their SLD peers, the conceptual understanding of the topic by the SLD was no less inclusive than their NA peers when accessed verbally. The journals demonstrated limited conceptual growth for the SLD. Further, while lexical density is important to the development of knowledge in science, this study suggests the "conceptual density" may be another important indicator to examine.
Social discourses of healthy eating. A market segmentation approach.
Chrysochou, Polymeros; Askegaard, Søren; Grunert, Klaus G; Kristensen, Dorthe Brogård
2010-10-01
This paper proposes a framework of discourses regarding consumers' healthy eating as a useful conceptual scheme for market segmentation purposes. The objectives are: (a) to identify the appropriate number of health-related segments based on the underlying discursive subject positions of the framework, (b) to validate and further describe the segments based on their socio-demographic characteristics and attitudes towards healthy eating, and (c) to explore differences across segments in types of associations with food and health, as well as perceptions of food healthfulness.316 Danish consumers participated in a survey that included measures of the underlying subject positions of the proposed framework, followed by a word association task that aimed to explore types of associations with food and health, and perceptions of food healthfulness. A latent class clustering approach revealed three consumer segments: the Common, the Idealists and the Pragmatists. Based on the addressed objectives, differences across the segments are described and implications of findings are discussed.

Discourse analysis following the work of Michel Foucault has become a valuable methodology in the critical analysis of a broad range of topics relating to health. However, it can be a daunting task, in that there seems to be both a huge number of possible approaches to carrying out this type of project, and an abundance of different, often conflicting, opinions about what counts as 'Foucauldian'. This article takes the position that methodological design should be informed by ongoing discussion and applied as appropriate to a particular area of inquiry. The discussion given offers an interpretation and application of Foucault's methodological principles, integrating a reading of Foucault with applications of his work by other authors, showing how this is then applied to interrogate the practice of vocational rehabilitation. It is intended as a contribution to methodological discussion in this area, offering an interpretation of various methodological elements described by Foucault, alongside specific application of these aspects.
Quantifiers are incrementally interpreted in context, more than less

Language interpretation is often assumed to be incremental. However, our studies of quantifier expressions in isolated sentences found N400 event-related brain potential (ERP) evidence for partial but not full immediate quantifier interpretation (Urbach & Kutas, 2010). Here we tested similar quantifier expressions in pragmatically supporting discourse contexts (Alex was an unusual toddler. Most/Few kids prefer sweets/vegetables…) while participants made plausibility judgments (Experiment 1) or read for comprehension (Experiment 2). Control Experiments 3A (plausibility) and 3B (comprehension) removed the discourse contexts. Quantifiers always modulated typical and/or atypical word N400 amplitudes. However, only the real-time N400 effects only in Experiment 2 mirrored offline quantifier and typicality crossover interaction effects for plausibility ratings and cloze probabilities. We conclude that quantifier expressions can be interpreted fully and immediately, though pragmatic and task variables appear to impact the speed and/or depth of quantifier interpretation.

We examined the progression of lexical-retrieval deficits in individuals with neuropathologically determined Alzheimer's disease (AD; n = 23) and a comparison group without criteria for AD (n = 24) to determine whether linguistic changes were a significant marker of the disease. Our participants underwent multiple administrations of a neuropsychological battery, with initial administration occurring on average 16 years prior to death. The battery included the Boston Naming Test (BNT), a letter fluency task (FAS), and written description of the Cookie Theft Picture (CTP). Repeated measures analysis revealed that the AD-group showed progressively greater decline in FAS and CTP lexical performance than the comparison group. Cross-sectional time-specific group comparisons indicated that the CTP differentiated performance between the two groups at 7–9 years prior to death and FAS and BNT only at 2–4 years. These results suggest that lexical-retrieval deficits in written discourse serve as an early indicator of AD. PMID:23985011

Current reforms in mathematics education advocate the development of mathematical learning communities in which students have opportunities to engage in mathematical discourse and classroom practices which underlie algebraic reasoning. This article specifically addresses the pedagogical actions teachers take which structure student engagement in dialogical discourse and activity which facilitates early algebraic reasoning. Using videotaped recordings of classroom observations, the teacher and researcher collaboratively examined the classroom practices and modified the participatory practices to develop a learning environment which supported early algebraic reasoning. Facilitating change in the classroom environment was a lengthy process which required consistent and ongoing attention initially to the social norms and then to the socio-mathematical norms. Specific pedagogical actions such as the use of specifically designed tasks, materials and representations and a constant press for justification and generalisation were required to support students to link their numerical understandings to algebraic reasoning.

This research examines the interplay of scientific discourse and students' sense of self among four Navajo (Dine) women as they major in science at a university in the southwestern United States. This dissertation research is an ethnographic case study of Navajo women as they were completing their final year of undergraduate study in the life sciences at a university. How do Navajo women express their identity in Western science at the university? What role does scientific discourse play in this process? This research employs a feminist poststructural approach to language and expands the way discourse has typically been addressed in science education. I expand the notion of discourse through poststructuralism by recognizing the co-constitutive role of language in fashioning realities and generating meaning. Data sources in this study included transcripts from one-on-one interviews, electronic correspondence (e-mail), observations of social contexts on campus, students' writing for science courses, university policy statements, departmental outcomes assessments, web profiles of student research in science, and a researcher's reflective journal. This study took place beginning in January 2002 and continued through May of 2003 at the University of New Mexico. After completing the thematic (constant comparative analysis) and an analysis of metaphors, I "retold" or "restoried" the narratives collected during interviews. In the cross case analysis, I compared each participant's description of those discursive spaces that afforded engagement with science, and those locations where their awareness of academic language was heightened in a process of metadiscourse. I identified these spaces as locations of possibility in which students and their mentors (or instructors) valued connected knowing, acknowledged each other's history, culture, and knowledge, and began speaking to each other subject-to-subject to challenge normative views of schooling. The participants in this research located spaces in which they authored themselves: study groups, a research project on invasive plants, the American Indian Medial Association, and a community college. The women in this study selectively accommodated elements of Western science that were consistent with their identity as they positioned themselves in service to family, community, and tribe, and also sought positions beyond the objectified gaze of the institution.
Anticipating explanations in relative clause processing.

2011-03-01
We show that comprehenders' expectations about upcoming discourse coherence relations influence the resolution of local structural ambiguity. We employ cases in which two clauses share both a syntactic relationship and a discourse relationship, and hence in which syntactic and discourse processing might be expected to interact. An off-line sentence-completion study and an on-line self-paced reading study examined readers' expectations for high/low relative-clause attachments following implicit-causality and non-implicit causality verbs (John detests/babysits the children of the musician who…). In the off-line study, the widely reported low-attachment preference for English is observed in the non-implicit causality condition, but this preference gives way to more high attachments in the implicit-causality condition in cases in which (i) the verb's causally implicated referent occupies the high-attachment position and (ii) the relative clause provides an explanation for the event described by the matrix clause (e.g., …who are arrogant and rude). In the on-line study, a similar preference for high attachment emerges in the implicit-causality context-crucially, before the occurrence of any linguistic evidence that the RC does in fact provide an explanation-whereas the low-attachment preference is consistent elsewhere. These findings constitute the first demonstration that expectations about ensuing discourse coherence relationships can elicit full reversals in syntactic attachment preferences, and that these discourse-level expectations can affect on-line disambiguation as rapidly as lexical and morphosyntactic cues.

The Effect of Task Instructions on Students' Use of Repetition in Argumentative Discourse
NASA Astrophysics Data System (ADS)
Gilabert, Sandra; Garcia-Mila, Merce; Felton, Mark K.
2013-11-01
The reasoning belief of argumentum ad nauseam assumes that when someone repeats something often enough, he or she becomes more convincing. The present paper analyses the use of this strategy by seventh-grade students in an argumentation task. Sixty-five students (mean age: 12.2, SD = 0.4) from a public school in a mid-sized urban environment took part in the study. The students were asked to either argue to convince an opposing partner or argue to reach consensus with an opposing partner on three dilemmas that dealt with energy sources. Data were gathered according to a between-groups design that included one independent variable (argumentative goal: to convince vs. to reach consensus) and one dependent variable (the degree of argumentative repetitions). We predicted that in the condition to convince their partner, the students would use the repetition strategy more often in their attempts to be persuasive. Our findings show that the mean number of argumentative repetitions was significantly higher for the persuasion group for both of the most frequent argumentative structures (claim and claim data). The mean percentage of repeated claims for the persuasion condition was 86.2 vs. 69.0 for the consensus condition. For the claim data, the mean percentage for the persuasion group was 35.2 vs. 24.3 for the consensus group. Also, students in the persuasion group tended to repeat one idea many times rather than repeating many ideas a few times within the same argumentative structure. The results of our study support the hypothesis that the goal of the argumentative task mediates argumentative discourse and, more concretely, the rate of repetitions and the conceptual diversity of the statements. These differences in rates of repetition and conceptual diversity are related to the amount of learning produced by the instructional goal. We apply Mercer's idea that not all classroom argumentation tasks promote learning equally.

Computer templates in chronic disease management: ethnographic case study in general practice.
Swinglehurst, Deborah; Greenhalgh, Trisha; Roberts, Celia

To investigate how electronic templates shape, enable and constrain consultations about chronic diseases. Ethnographic case study, combining field notes, video-recording, screen capture with a microanalysis of talk, body language and data entry-an approach called linguistic ethnography. Two general practices in England. Ethnographic observation of administrative areas and 36 nurse-led consultations was done. Twenty-four consultations were directly observed and 12 consultations were video-recorded alongside computer screen capture. Consultations were transcribed using conversation analysis conventions, with notes on body language and the electronic record. The analysis involved repeated rounds of viewing video, annotating field notes, transcription and microanalysis to identify themes. The data was interpreted using discourse analysis, with attention to the sociotechnical theory. Consultations centred explicitly or implicitly on evidence-based protocols inscribed in templates. Templates did not simply identify tasks for completion, but contributed to defining what chronic diseases were, how care was being delivered and what it meant to be a patient or professional in this context. Patients' stories morphed into data bytes; the particular became generalised; the complex was made discrete, simple and manageable; and uncertainty became categorised and contained. Many consultations resembled bureaucratic encounters, primarily oriented to completing data fields. We identified a tension, sharpened by the template, between different framings of the patient-as 'individual' or as 'one of a population'. Some clinicians overcame this tension, responding creatively to prompts within a dialogue constructed around the patient's narrative. Despite their widespread implementation, little previous research has examined how templates are actually used in practice. Templates do not simply document the tasks of chronic disease management but profoundly change the nature of this work. Designed to assure standards of 'quality' care they contribute to bureaucratisation of care and may marginalise aspects of quality care which lie beyond their focus. Creative work is required to avoid privileging 'institution-centred' care over patient-centred care.

In this study an interpretive learning framework that aims to measure learning on the classroom level is introduced. In order to develop and evaluate the value of the framework, a theoretical/empirical study is designed. The researcher attempted to illustrate how the proposed framework provides insights on the problem of classroom-level learning. The framework is developed by construction of connections between the current literature on science learning and Wittgenstein's language-game theory. In this framework learning is defined as change of classroom language-game or discourse. In the proposed framework, learning is measured by analysis of classroom discourse. The empirical explanation power of the framework is evaluated by applying the framework in the analysis of learning in a fifth-grade science classroom. The researcher attempted to analyze how students' colloquial discourse changed to a discourse that bears more resemblance to science discourse. The results of the empirical part of the investigation are presented in three parts: first, the gap between what students did and what they were supposed to do was reported. The gap showed that students during the classroom inquiry wanted to do simple comparisons by direct observation, while they were supposed to do tool-assisted observation and procedural manipulation for a complete comparison. Second, it was illustrated that the first attempt to connect the colloquial to science discourse was done by what was immediately intelligible for students and then the teacher negotiated with students in order to help them to connect the old to the new language-game more purposefully. The researcher suggested that these two events in the science classroom are critical in discourse change. Third, it was illustrated that through the academic year, the way that students did the act of comparison was improved and by the end of the year more accurate causal inferences were observable in classroom communication. At the end of the study, the researcher illustrates that the application of the proposed framework resulted in an improved version of the framework. The improved version of the proposed framework is more connected to the topic of science learning, and is able to measure the change of discourse in higher resolution.

Task allocation model for minimization of completion time in distributed computer systems

1993-08-01
A task in a distributed computing system consists of a set of related modules. Each of the modules will execute on one of the processors of the system and communicate with some other modules. In addition, precedence relationships may exist among the modules. Task allocation is an essential activity in distributed-software design. This activity is of importance to all phases of the development of a distributed system. This paper establishes task completion-time models and task allocation models for minimizing task completion time. Current work in this area is either at the experimental level or without the consideration of precedence relationships among modules. The development of mathematical models for the computation of task completion time and task allocation will benefit many real-time computer applications such as radar systems, navigation systems, industrial process control systems, image processing systems, and artificial intelligence oriented systems.

Pragmatic language impairments are nearly universal in autism spectrum disorders (ASD). Discourse requires that we monitor information that is shared or mutually known, called "common ground." While many studies have examined the role of Theory of Mind (ToM) in such impairments, few have examined working memory (WM). Common ground impairments in ASD could reflect limitations in both WM and ToM. This study explored common ground use in youth ages 8-17 years with high-functioning ASD (n = 13) and typical development (n = 22); groups did not differ on age, gender, IQ, or standardized language. We tracked participants' eye movements while they performed a discourse task in which some information was known only to the participant (e.g., was privileged; a manipulation of ToM). In addition, the amount of privileged information varied (a manipulation of WM). All participants were slower to fixate the target when considering privileged information, and this effect was greatest during high WM load trials. Further, the ASD group was more likely to fixate competing (non-target) shapes. Predictors of fixation patterns included ASD symptomatology, language ability, ToM, and WM. Groups did not differ in ToM. Individuals with better WM fixated the target more rapidly, suggesting an association between WM capacity and efficient discourse. In addition to ToM knowledge, WM capacity constrains common ground representation and impacts pragmatic skills in ASD. Social impairments in ASD are thus associated with WM capacity, such that deficits in domain-general, nonsocial processes such as WM exert an influence during complex social interactions.

Objective This paper presents a coreference resolution system for clinical narratives. Coreference resolution aims at clustering all mentions in a single document to coherent entities. Materials and methods A knowledge-intensive approach for coreference resolution is employed. The domain knowledge used includes several domain-specific lists, a knowledge intensive mention parsing, and task informed discourse model. Mention parsing allows us to abstract over the surface form of the mention and represent each mention using a higher-level representation, which we call the mention's semantic representation (SR). SR reduces the mention to a standard form and hence provides better support for comparing and matching. Existing coreference resolution systems tend to ignore discourse aspects and rely heavily on lexical and structural cues in the text. The authors break from this tradition and present a discourse model for “person” type mentions in clinical narratives, which greatly simplifies the coreference resolution. Results This system was evaluated on four different datasets which were made available in the 2011 i2b2/VA coreference challenge. The unweighted average of F1 scores (over B-cubed, MUC and CEAF) varied from 84.2% to 88.1%. These experiments show that domain knowledge is effective for different mention types for all the datasets. Discussion Error analysis shows that most of the recall errors made by the system can be handled by further addition of domain knowledge. The precision errors, on the other hand, are more subtle and indicate the need to understand the relations in which mentions participate for building a robust coreference system. Conclusion This paper presents an approach that makes an extensive use of domain knowledge to significantly improve coreference resolution. The authors state that their system and the knowledge sources developed will be made publicly available. PMID:22781192
Delegation of clinical dietetic tasks in military and civilian hospitals: implications for practice.
Myers, M E; Gregoire, M B; Spears, M C
1991-12-01
The purposes of our research were two-fold: to determine perceptions of the quality of task performance and to identify dietetic personnel currently performing clinical dietetic tasks in military and civilian hospitals. Questionnaires were returned from 309 dietitians and 208 dietetic support personnel at 151 military and civilian hospitals (73% response overall). For tasks completed by support personnel, no task was rated as having optimum quality, 1 was rated as highly acceptable, 6 as acceptable, 19 as somewhat unacceptable, and 4 as unacceptable. Current performance ratings indicated that 1 task was performed solely by dietitians, 21 were completed by dietitians with assistance, 6 were completed jointly by dietitians and support personnel, 2 were completed by support personnel with supervision by dietitians, and no task was completed independently by support personnel. Tasks were grouped into four categories: basic clinical dietetics (11 tasks), intermediate and in-depth clinical dietetics (12 tasks), outpatient nutrition clinic (5 tasks), and nutrition education (community) (4 tasks). Quality scores for the US Air Force (USAF) hospitals were higher for all task categories except intermediate and in-depth clinical dietetic tasks. The quality scores of support personnel were higher than those of dietitians for all task categories. The USAF performance scores indicated significantly more involvement of support personnel. Generally, the performance scores of dietitians increased with experience; the scores of support personnel decreased with experience. Correlations between quality and performance ratings for individual tasks revealed low to moderate relationships. Our results suggest that additional delegation of tasks to dietetic support personnel may be possible without negatively affecting perceptions of the quality of task outcome.(ABSTRACT TRUNCATED AT 250 WORDS)
Color adaptation induced from linguistic description of color
Zheng, Liling; Huang, Ping; Zhong, Xiao; Li, Tianfeng; Mo, Lei
2017-01-01
Recent theories propose that language comprehension can influence perception at the low level of perceptual system. Here, we used an adaptation paradigm to test whether processing language caused color adaptation in the visual system. After prolonged exposure to a color linguistic context, which depicted red, green, or non-specific color scenes, participants immediately performed a color detection task, indicating whether they saw a green color square in the middle of a white screen or not. We found that participants were more likely to perceive the green color square after listening to discourses denoting red compared to discourses denoting green or conveying non-specific color information, revealing that language comprehension caused an adaptation aftereffect at the perceptual level. Therefore, semantic representation of color may have a common neural substrate with color perception. These results are in line with the simulation view of embodied language comprehension theory, which predicts that processing language reactivates the sensorimotor systems that are engaged during real experience.

Biopolitics and the `subject' of labor in science education
NASA Astrophysics Data System (ADS)
Bazzul, Jesse
2017-12-01
Viewing science education as a site of biopolitical engagement—intervention into forces that seek to define, control, and exploit life (biopower)—requires that science educators ask after how individuals and populations are governed by technologies of power. In this paper, I argue that microanalyses, the analysis of everyday practices and discourses, are integral to biopolitical engagement, are needed to examine practices that constitute subjectivities and maintain oppressive social conditions. As an example of a microanalysis I will discuss how repetitive close-ended lab/assessment tasks, as well as discourses surrounding careers in science, can work to constitute students as depoliticized, self-investing subjects of human capital. I also explore the relationship between science education, (bio)labor and its relation to biopolitics, which remains an underdeveloped area of science education. This paper, part of my doctoral work, began to take shape in 2011, shortly after the 2008 economic crisis achieved a tiny breached in the thick neoliberal stupor of everyday (educational) life.

After prolonged exposure to a color linguistic context, which depicted red, green, or non-specific color scenes, participants immediately performed a color detection task, indicating whether they saw a green color square in the middle of a white screen or not. We found that participants were more likely to perceive the green color square after listening to discourses denoting red compared to discourses denoting green or conveying non-specific color information, revealing that language comprehension caused an adaptation aftereffect at the perceptual level. Therefore, semantic representation of color may have a common neural substrate with color perception. These results are in line with the simulation view of embodied language comprehension theory, which predicts that processing language reactivates the sensorimotor systems that are engaged during real experience.
Eugenics, medicine and psychiatry in Peru.
Stucchi-Portocarrero, Santiago
2018-03-01
Eugenics was defined by Galton as 'the science which deals with all influences that improve the inborn qualities of a race'. In Peru, eugenics was related to social medicine and mental hygiene, in accordance with the neo-Lamarckian orientation, that predominated in Latin America. Peruvian eugenists assumed the mission of fighting hereditary and infectious diseases, malnutrition, alcoholism, drug addiction, prostitution, criminality and everything that threatened the future of the 'Peruvian race'. There were some enthusiastic advocates of 'hard' eugenic measures, such as forced sterilization and eugenic abortion, but these were never officially implemented in Peru (except for the compulsory sterilization campaign during the 1995-2000 period). Eugenics dominated scientific discourse during the first half of the twentieth century, but eugenic discourse did not disappear completely until the 1970s.
Reading comprehension in Parkinson's disease.
Murray, Laura L; Rutledge, Stefanie
2014-05-01
Although individuals with Parkinson's disease (PD) self-report reading problems and experience difficulties in cognitive-linguistic functions that support discourse-level reading, prior research has primarily focused on sentence-level processing and auditory comprehension. Accordingly, the authors investigated the presence and nature of reading comprehension in PD, hypothesizing that (a) individuals with PD would display impaired accuracy and/or speed on reading comprehension tests and (b) reading performances would be correlated with cognitive test results. Eleven adults with PD and 9 age- and education-matched control participants completed tests that evaluated reading comprehension; general language and cognitive abilities; and aspects of attention, memory, and executive functioning. The PD group obtained significantly lower scores on several, but not all, reading comprehension, language, and cognitive measures. Memory, language, and disease severity were significantly correlated with reading comprehension for the PD group. Individuals in the early stages of PD without dementia or broad cognitive deficits can display reading comprehension difficulties, particularly for high- versus basic-level reading tasks. These reading difficulties are most closely related to memory, high-level language, and PD symptom severity status. The findings warrant additional research to delineate further the types and nature of reading comprehension impairments experienced by individuals with PD.
Negative emotion impacts memory for verbal discourse in pediatric bipolar disorder.

2011-05-01
Cognitive and emotional deficits have been documented in youth with pediatric bipolar disorder (PBD); however, to date, a systematic evaluation of comprehension and memory for verbally presented information has not been conducted. The effect of emotion on comprehension and memory for verbally presented material also has not been examined. We examined whether youth with PBD have difficulty recalling the big picture (macrostructure) as well as the story details (microstructure). A total of 35 youth with PBD and 25 healthy controls completed an Affective Story Task. A psychological processing model allowed for the examination of both the macrostructure and microstructure of language comprehension. Youth with PBD were capable of comprehending the gist of the stories and were not impaired by emotion when comprehending and remembering macrostructure. However, negative emotional material was found to proactively interfere with the encoding and recall of microstructure. Level of depression appeared to impact recall of microstructure, but not macrostructure. Negatively valenced material may impair subsequent comprehension and memory for details among youth with PBD. This deficit could impact the daily functioning of these youth, as the perception of negative affect may derail aspects of successful comprehension and learning. © 2011 John Wiley and Sons A/S.

Factors influencing the academic motivation of individual college students.
Yoshida, Masahiro; Tanaka, Masaaki; Mizuno, Kei; Ishii, Akira; Nozaki, Kumi; Urakawa, Ayako; Cho, Yuki; Kataoka, Yosky; Watanabe, Yasuyoshi
2008-10-01
Motivation is an important psychological concept in academic learning. Subjects performed jigsaw puzzle and square puzzle sessions (as difficulty variant task) and 80%, 50%, and 20% completion sessions (as completion variant task). After square puzzle or 20% completion sessions, subjective motivation decreased. Although baseline scores on an academic motivation scale were negatively correlated with changes in subjective motivation for the square puzzle session, a positive correlation was observed for the 20% completion session. These suggest that while continual completion of facile task trials may support the motivation of college students with lower academic motivation, attempting difficult task trials may sustain that of those with higher academic motivation.
Knowledge-rich temporal relation identification and classification in clinical notes
D’Souza, Jennifer; Ng, Vincent
2014-01-01
Motivation: We examine the task of temporal relation classification for the clinical domain. Our approach to this task departs from existing ones in that it is (i) ‘knowledge-rich’, employing sophisticated knowledge derived from discourse relations as well as both domain-independent and domain-dependent semantic relations, and (ii) ‘hybrid’, combining the strengths of rule-based and learning-based approaches. Evaluation results on the i2b2 Clinical Temporal Relations Challenge corpus show that our approach yields a 17–24% and 8–14% relative reduction in error over a state-of-the-art learning-based baseline system when gold-standard and automatically identified temporal relations are used, respectively.

Sustainable management of marine resources raises great challenges. Working with this socio-scientific issue in the classroom requires students to apply complex models about energy flow and trophic pyramids in order to understand that food chains represent transfer of energy, to construct meanings for sustainable resources management through discourse, and to connect them to actions and decisions in a real-life context. In this paper we examine the process of elaboration of plans for resources management in a marine ecosystem by 10th grade students (15-16 year) in the context of solving an authentic task. A complete class ( N = 14) worked in a sequence about ecosystems. Working in small groups, the students made models of energy flow and trophic pyramids, and used them to solve the problem of feeding a small community for a long time. Data collection included videotaping and audiotaping of all of the sessions, and collecting the students' written productions. The research objective is to examine the process of designing a plan for sustainable resources management in terms of the discursive moves of the students across stages in contextualizing practices, or different degrees of complexity (Jiménez-Aleixandre & Reigosa International Journal of Science Education, 14(1): 51-61 2006), understood as transformations from theoretical statements to decisions about the plan. The analysis of students' discursive moves shows how the groups progressed through stages of connecting different models, between them and with the context, in order to solve the task. The challenges related to taking this sustainability issue to the classroom are discussed.

Posture, vision, and instrumentation limitations are the main predicaments of conventional laparoscopy. To combine the ETHOS surgical chair, the three-dimensional laparoscope, and the Radius Surgical System manipulators, and compare the system with conventional laparoscopy and da Vinci in terms of task completion times and discomfort. Fifteen trainees performed the three main laparoscopic suturing tasks of the Heilbronn training program (IV: simulation of dorsal venous complex suturing; V: circular suturing of tubular structure; and VI: urethrovesical anastomosis) in a pelvi trainer. The tasks were performed conventionally, utilizing the three devices, and robotically. Task completion times were recorded and the surgeon discomfort was evaluated using questionnaires. Task completion times were compared using nonparametric Wilcoxon signed rank test and ergonomic scores were compared using Pearson chi-square test. The use of the full laparoscopic set (ETHOS chair, three-dimensional laparoscopic camera, Radius Surgical System needle holders), resulted in a significant improvement of the completion time of the three tested tasks compared with conventional laparoscopy (p<0.001) and similar to da Vinci surgery. After completing Tasks IV, V, and VI conventionally, 12 (80%), 13 (86.7%), and 13 (86.7%) of the 15 trainees, respectively, reported heavy total discomfort. The full laparoscopic system nullified heavy discomfort for Tasks IV and V and minimized it (6.7%) for the most demanding Task VI. Especially for Task VI, all trainees gained benefit, by using the system, in terms of task completion times and discomfort. The limited trainee robotic experience and the questionnaire subjectivity could be a potential limitation. The ergonomic laparoscopic system offers significantly improved task completion times and ergonomy than conventional laparoscopy. Furthermore, it demonstrates comparable results to robotic surgery. The study was conducted in a pelvi trainer and no patients were recruited. Copyright © 2016 European Association of Urology. Published by Elsevier B.V. All rights reserved.

In this paper, we introduce an agent-based simulation for investigating the impact of social factors on the formation and evolution of task-oriented groups. Task-oriented groups are created explicitly to perform a task, and all members derive benefits from task completion. However, even in cases when all group members act in a way that is locally optimal for task completion, social forces that have mild effects on choice of associates can have a measurable impact on task completion performance. In this paper, we show how our simulation can be used to model the impact of stereotypes on group formation. In our simulation, stereotypes are based on observable features, learned from prior experience, and only affect an agent's link formation preferences. Even without assuming stereotypes affect the agents' willingness or ability to complete tasks, the long-term modifications that stereotypes have on the agents' social network impair the agents' ability to form groups with sufficient diversity of skills, as compared to agents who form links randomly. An interesting finding is that this effect holds even in cases where stereotype preference and skill existence are completely uncorrelated.

We introduce a novel paradigm for studying the cognitive processes used by listeners within interactive settings. This paradigm places the talker and the listener in the same physical space, creating opportunities for investigations of attention and comprehension processes taking place during interactive discourse situations. An experiment was conducted to compare results from previous research using videotaped stimuli to those obtained within the live face-to-face task paradigm. A headworn apparatus is used to briefly display LEDs on the talker's face in four locations as the talker communicates with the participant. In addition to the primary task of comprehending speeches, participants make a secondary task light detection response. In the present experiment, the talker gave non-emotionally-expressive speeches that were used in past research with videotaped stimuli. Signal detection analysis was employed to determine which areas of the face received the greatest focus of attention. Results replicate previous findings using videotaped methods.

The invention is an apparatus and method of biofeedback training for attaining a physiological state optimally consistent with the successful performance of a task, wherein the probability of successfully completing the task is made is inversely proportional to a physiological difference value, computed as the absolute value of the difference between at least one physiological signal optimally consistent with the successful performance of the task and at least one corresponding measured physiological signal of a trainee performing the task. The probability of successfully completing the task is made inversely proportional to the physiological difference value by making one or more measurable physical attributes of the environment in which the task is performed, and upon which completion of the task depends, vary in inverse proportion to the physiological difference value.
Socialization into science: An ethnographic study in a field research station
NASA Astrophysics Data System (ADS)
Calovini, Theresa Ann
While the place of language in building the tasks and activities of the science classroom has received attention in the education literature, how students do the work of affiliation building through language remains poorly understood. This dissertation is based on ethnographic research in an apprenticeship learning situation at a biological field research station. I carried out this research with five undergraduates apprentices. I focus on how the language used in this apprenticeship situation positioned the apprentices with science. Issues of access and diversity in science education have motivated this research but this point can be missed because the five apprentices were all fairly successful in university science. They had all secured their job for the summer as paid research assistants. Yet, even with these successful students, science had a complicated place in their lives. I draw on Gee's (1999) notion of Discourse to understand this complexity. I focus on four Discourses--- Science, Knowing about the Animals, Senior Projects and RAships, and Relationships ---which were important in the apprentices' learning about and socialization with science. I try to understand the inter-workings of these four Discourses through a detailed analysis of three conversations involving one of the participants, Michelle. Michelle's use of narrative emerged as a linguistic resource which she used to explore dilemmas she experienced in the tensions between these four Discourses. Michelle was in many ways an ideal apprentice. She did her job well and she sought and received expert advice on her Senior project. Nonetheless, Michelle faced obstacles in her pursuit of a career in science and these obstacles related to language use and her use of narrative. I show how her use of narrative either facilitated or impeded her learning, depending on the context of the interaction. My analysis of Discourse points to important issues in language use by both students and teachers, with broad implications across a range of teaching/learning contexts. I describe multi-genre science reports as a pedagogy that might allow flexibility for students' representations with science, a flexibility that might be necessary given the complicated ways science plays out in the lives of students.

Naturalistic Assessment of Executive Function and Everyday Multitasking in Healthy Older Adults
McAlister, Courtney; Schmitter-Edgecombe, Maureen
2013-01-01
Everyday multitasking and its cognitive correlates were investigated in an older adult population using a naturalistic task, the Day Out Task. Fifty older adults and 50 younger adults prioritized, organized, initiated and completed a number of subtasks in a campus apartment to prepare for a day out (e.g., gather ingredients for a recipe, collect change for a bus ride). Participants also completed tests assessing cognitive constructs important in multitasking. Compared to younger adults, the older adults took longer to complete the everyday tasks and more poorly sequenced the subtasks. Although they initiated, completed, and interweaved a similar number of subtasks, the older adults demonstrated poorer task quality and accuracy, completing more subtasks inefficiently. For the older adults, reduced prospective memory abilities were predictive of poorer task sequencing, while executive processes and prospective memory were predictive of inefficiently completed subtasks. The findings suggest that executive dysfunction and prospective memory difficulties may contribute to the age-related decline of everyday multitasking abilities in healthy older adults. PMID:23557096

Dissociating word stem completion and cued recall as a function of divided attention at retrieval.
Clarke, A J Benjamin; Butler, Laurie T
2008-10-01
The aim of this study was to investigate the widely held, but largely untested, view that implicit memory (repetition priming) reflects an automatic form of retrieval. Specifically, in Experiment 1 we explored whether a secondary task (syllable monitoring), performed during retrieval, would disrupt performance on explicit (cued recall) and implicit (stem completion) memory tasks equally. Surprisingly, despite substantial memory and secondary costs to cued recall when performed with a syllable-monitoring task, the same manipulation had no effect on stem completion priming or on secondary task performance. In Experiment 2 we demonstrated that even when using a particularly demanding version of the stem completion task that incurred secondary task costs, the corresponding disruption to implicit memory performance was minimal. Collectively, the results are consistent with the view that implicit memory retrieval requires little or no processing capacity and is not seemingly susceptible to the effects of dividing attention at retrieval.
Analysis of film cooling in rocket nozzles

This report summarizes the findings on the NASA contract NAG8-212, Task No. 3. The overall project consists of three tasks, all of which have been successfully completed. In addition, some supporting supplemental work, not required by the contract, has been performed and is documented herein. Task 1 involved the modification of the wall functions in the code FDNS (Finite Difference Navier-Stokes) to use a Reynolds Analogy-based method. This task was completed in August, 1992. Task 2 involved the verification of the code against experimentally available data. The data chosen for comparison was from an experiment involving the injection of helium from a wall jet. Results obtained in completing this task also show the sensitivity of the FDNS code to unknown conditions at the injection slot. This task was completed in September, 1992. Task 3 required the computation of the flow of hot exhaust gases through the P&W 40K subscale nozzle. Computations were performed both with and without film coolant injection. This task was completed in July, 1993. The FDNS program tends to overpredict heat fluxes, but, with suitable modeling of backside cooling, may give reasonable wall temperature predictions. For film cooling in the P&W 40K calorimeter subscale nozzle, the average wall temperature is reduced from 1750R to about 1050R by the film cooling. The average wall heat flux is reduced by a factor of 3.

To understand the influence of academic discourses about family medicine on medical students' professional identity construction during undergraduate training. The authors used a multiple case study research design involving international medical schools, one each from Canada, France, Spain, and the United Kingdom (UK). The authors completed the fieldwork between 2007 and 2009 by conducting 18 focus groups (with 132 students) and 67 semistructured interviews with educators and by gathering pertinent institutional documents. They carried out discursive thematic analyses of the verbatim transcripts and then performed within- and cross-case analyses. The most striking finding was the diverging responses between those at the UK school and those at the other schools. In the UK case, family medicine was recognized as a prestigious academic discipline; students and faculty praised the knowledge and skills of family physicians, and students more often indicated their intent to pursue family medicine. In the other cases, family medicine was not well regarded by students or faculty. This was expressed overtly or through a paradoxical academic discourse that stressed the importance of family medicine to the health care system while decrying its lack of innovative technology and the large workload-to-income ratio. Students at these schools were less likely to consider family medicine. These results stress the influence of academic discourses on medical students' ability to identify with the practice of family medicine. Educators must consider processes of professional identity formation during undergraduate medical training as they develop and reform medical education.

The present article investigates explanations for gendered trends in Physics and Engineering access, reporting findings from a large-scale study funded by the UK Economic and Social Research Council and drawing primarily on data from interviews with 132 15-16 year-old adolescents and their parents. Survey results in our study and elsewhere show strong gender disparities in anticipated pursuit of Physics after completion of compulsory education. In order to explore the constructions of gender and Physics underlying these trends, we focus on qualitative interview data, applying Foucaultian analysis of discourse to investigate gendered narratives underpinning adolescents' and their parents' articulations. This analysis reveals three key discourses at work on the topic of women's access to Physics: (a) equality of opportunity, (b) continued gender discrimination in and around Physics, and (c) Physics as quintessentially masculine. We additionally identify five distinct narratives supporting the discourse of physics as masculine. These various discourses and narratives are interrogated, and their implications explored. We conclude that it is only by disrupting prevalent constructions of the Physical sciences as a masculine and "hard" domain will we increase the presence of women in the sector. Working with young people to analyse and deconstruct the discursive assumptions made in relation to gender and Physics, as well as further work to increase accessibility and broaden representation in Physics, may be fruitful ways to challenge these longstanding associations between Physics and masculinity.

Craving among smokers is increased by stress and exposure to smoking-related visual cues. However, few experimental studies have tested both elicitors concurrently and considered how exposures may interact to influence craving. The current study examined craving in response to stress and visual cue exposure, separately and in succession, in order to better understand the relationship between craving elicitation and the elicitor. Thirty-nine smokers (21 males) who forwent smoking for 30 minutes were randomized to complete a stress task and a visual cue task in counterbalanced orders (creating the experimental groups); for the cue task, counterbalanced blocks of neutral, motivational control, and smoking images were presented. Self-reported craving was assessed after each block of visual stimuli and stress task, and after a recovery period following each task. As expected, the stress and smoking images generated greater craving than neutral or motivational control images (p < .001). Interactions indicated craving in those who completed the stress task first differed from those who completed the visual cues task first (p < .05), such that stress task craving was greater than all image type craving (all p's < .05) only if the visual cue task was completed first. Conversely, craving was stable across image types when the stress task was completed first. Findings indicate when smokers are stressed, visual cues have little additive effect on craving, and different types of visual cues elicit comparable craving. These findings may imply that once stressed, smokers will crave cigarettes comparably notwithstanding whether they are exposed to smoking image cues.
Communication as group process mediator of aircrew performance

Kanki, Barbara G.; Foushee, H. Clayton
1989-01-01
Considering recent operating experience as a group-level input factor, aspects of the communication process between crewmembers (captain and first officer) were explored as a possible mediator to performance. Communication patterns were defined by a speech-act typology adapted for the flight-deck setting and distinguished crews that had previously flown together (FT) from those that had not flown together (NFT). A more open communication channel and greater first officer participation in task-related topics was shown by FT crews, while NFT crews engaged in more nontask discourse.
Filling the gaps: A speeded word fragment completion megastudy.
Heyman, Tom; Van Akeren, Liselotte; Hutchison, Keith A; Storms, Gert
2016-12-01
In the speeded word fragment completion task, participants have to complete fragments such as tom_to as quickly and accurately as possible. Previous work has shown that this paradigm can successfully capture subtle priming effects (Heyman, De Deyne, Hutchison, & Storms Behavior Research Methods, 47, 580-606, 2015). In addition, it has several advantages over the widely used lexical decision task. That is, the speeded word fragment completion task is more efficient, more engaging, and easier. Given its potential, we conducted a study to gather speeded word fragment completion norms. The goal of this megastudy was twofold. On the one hand, it provides a rich database of over 8,000 stimuli, which can, for instance, be used in future research to equate stimuli on baseline response times. On the other hand, the aim was to gain insight into the underlying processes of the speeded word fragment completion task. To this end, item-level regression and mixed-effects analyses were performed on the response latencies using 23 predictor variables. Since all items were selected from the Dutch Lexicon Project (Keuleers, Diependaele, & Brysbaert Frontiers in Psychology, 1, 174, 2010), we ran the same analyses on lexical decision latencies to compare the two tasks. Overall, the results revealed many similarities, but also some remarkable differences, which are discussed. We propose that both tasks are complementary when examining visual word recognition. The article ends with a discussion of potential process models of the speeded word fragment completion task.
Mission control of multiple unmanned aerial vehicles: a workload analysis.
Dixon, Stephen R; Wickens, Christopher D; Chang, Dervon
2005-01-01
With unmanned aerial vehicles (UAVs), 36 licensed pilots flew both single-UAV and dual-UAV simulated military missions. Pilots were required to navigate each UAV through a series of mission legs in one of the following three conditions: a baseline condition, an auditory autoalert condition, and an autopilot condition. Pilots were responsible for (a) mission completion, (b) target search, and (c) systems monitoring. Results revealed that both the autoalert and the autopilot automation improved overall performance by reducing task interference and alleviating workload. The autoalert system benefited performance both in the automated task and mission completion task, whereas the autopilot system benefited performance in the automated task, the mission completion task, and the target search task. Practical implications for the study include the suggestion that reliable automation can help alleviate task interference and reduce workload, thereby allowing pilots to better handle concurrent tasks during single- and multiple-UAV flight control.

“Survivor” has become a ubiquitous and largely unquestioned term in culture and cancer discourse. While anecdotal evidence suggests women with breast cancer find fault with survivor images and discourse, the extent to which women identify with or reject the survivor identity has not been empirically studied. This paper examines whether women treated for breast cancer embrace survivorship. Data come from 39 in-depth interviews with women in the United States who completed treatment for breast cancer 3 to 18 months prior to the interview. Despite the positive meanings attached to survivorship, many women altered the meaning of survivorship or rejected survivorship. In particular, the survivor discourse alienated women who struggle with the threat of recurrence, who feel their cancer experience was not severe enough to merit this title, or who desire a private disease experience. These findings illustrate the failure of our cultural conceptions of cancer to adequately reflect lived experience and highlight how individuals actively “craft” illness meanings. “I woke up, still alive. Does that mean ‘cured’?”Marilyn Hacker, 1994 (cited in Bahar, 2003) PMID:18450347

Selective alignment of brain responses by task demands during semantic processing.
Baggio, Giosuè
2012-04-01
The way the brain binds together words to form sentences may depend on whether and how the arising cognitive representation is to be used in behavior. The amplitude of the N400 effect in event-related brain potentials is inversely correlated with the degree of fit of a word's meaning into a semantic representation of the preceding discourse. This study reports a double dissociation in the latency characteristics of the N400 effect depending on task demands. When participants silently read words in a sentence context, without issuing a relevant overt response, greater temporal alignment over recording sites occurs for N400 onsets than peaks. If however a behavior is produced - here pressing a button in a binary probe selection task - exactly the opposite pattern is observed, with stronger alignment of N400 peaks than onsets. The peak amplitude of the N400 effect correlates best with the latency characteristic showing less temporal dispersion. These findings suggest that meaning construction in the brain is subtly affected by task demands, and that there is complex functional integration between semantic combinatorics and control systems handling behavioral goals.

Previous research has suggested that the topography of instructions (general vs. specific) may influence the likelihood that young children comply with instructions. The purpose of the current study was to compare the rates of task completion of a young man diagnosed with Asperger syndrome when provided with general and specific instructions pertaining to the task. The results showed that specific instructions occasioned higher levels of task completion, even when no differential reinforcement contingencies were in place.
Lessons learned from the usability assessment of home-based telemedicine systems.

At-home telemedicine visits are quickly becoming an acceptable alternative for in-person patient visits. However, little work has been done to understand the usability of these home-based telemedicine solutions. It is critical for user acceptance and real-world applicability to evaluate available telemedicine solutions within the context-specific needs of the users of this technology. To address this need, this study evaluated the usability of four home-based telemedicine software platforms: Doxy.me, Vidyo, VSee, and Polycom. Using a within-subjects experimental design, twenty participants were asked to complete a telemedicine session involving several tasks using the four platforms. Upon completion of these tasks for each platform, participants completed the IBM computer system usability questionnaire (CSUQ) and the NASA Task Load Index test. Upon completing the tasks on all four platforms, the participants completed a final post-test subjective questionnaire ranking the platforms based on their preference. Of the twenty participants, 19 completed the study. Statistically significant differences among the telemedicine software platforms were found for task completion time, total workload, mental demand, effort, frustration, preference ranking and computer system usability scores. Usability problems with installation and account creation led to high mental demand and task completion time, suggesting the participants preferred a system without such requirements. Majority of the usability issues were identified at the telemedicine initiation phase. The findings from this study can be used by software developers to develop user-friendly telemedicine systems.

What role does socialization play in the origins of prosocial behavior? We examined one potential socialization mechanism, parents' discourse about others' emotions with very young children in whom prosocial behavior is still nascent. Two studies are reported, one of sharing in 18- and 24-month-olds (n = 29), and one of instrumental and empathy-based helping in 18- and 30-month-olds (n = 62). In both studies, parents read age-appropriate picture books to their children and the content and structure of their emotion-related and internal state discourse were coded. Results showed that children who helped and shared more quickly and more often, especially in tasks that required more complex emotion understanding, had parents who more often asked them to label and explain the emotions depicted in the books. Moreover, it was parents' elicitation of children's talk about emotions rather than parents' own production of emotion labels and explanations that explained children's prosocial behavior, even after controlling for age. Thus, it is the quality, not the quantity, of parents' talk about emotions with their toddlers that matters for early prosocial behavior.
Job stability in skilled work and communication ability after moderate-severe traumatic brain injury
Meulenbroek, Peter; Turkstra, Lyn S.
2016-01-01
Purpose Communication deficits may play a critical role in maintaining employment after traumatic brain injury (TBI), but links between specific communication deficits and employment outcomes have not been determined. This study identified communication measures that distinguished stably employed versus unstably employed adults with TBI. Methods Participants were 31 adults with moderate-severe TBI who were employed full-time for at least 12 consecutive months before injury in skilled jobs and had attempted return to skilled jobs after injury. Sixteen had achieved stable employment (SE) post-injury, defined as full-time employment for ≥12 consecutive months; and 15 had unstable (UE) employment. Participants completed a battery of communication tests identified in a prior qualitative study of communication skills required for skilled work. Results Measures of spoken language comprehension, verbal reasoning, social inference, reading, and politeness in spoken discourse significantly discriminated between SE and UE groups. Two nested models were completed and compared. The first model excluded discourse data because of missing data for two UE and one SE participant. This model revealed that measures of verbal reasoning speed (β = −0.18, p = 0.05) and social inference (β = 0.19, p = 0.05) were predictive independent of the overall model. The second model included discourse data and was a better overall predictor of group membership (Likelihood ratio test, Model 1: 3.824, Model 2: 2.865). Conclusion Communication measures were positively associated with stable employment in skilled jobs after TBI. Clinicians should include assessment of communication for adults attempting return to work after TBI, paying specific attention to social inference and speed of verbal reasoning skills. PMID:25958999

Turkey has maintained liberal contraception and abortion policies since the 1980s. In 2012, the government proposed to restrict abortion; a bill limiting abortion was later drafted but never passed into law. Since the proposed restriction, women have reported difficulty accessing abortion services across Turkey. We aimed to better understand the current availability of abortion and reproductive health services in Istanbul and explore whether access to services has changed since 2012. In 2015, we completed 14 in-depth interviews with women and 11 semi-structured interviews with key informants. We transcribed all interviews and completed content and thematic analyses of the data. Key informants had good knowledge about the political discourse and the current abortion law. In contrast, women were familiar with the political discourse but had mixed information about the current status of abortion and were unsure about the legality of their own abortions. There was consensus that access to services has become more limited in the last five years due to the political climate, thus advocacy to prioritize reproductive health services, and abortion care in particular, in the public health system are needed.

Neural correlate of human inductive reasoning process is still unclear. Number series and letter series completion are two typical inductive reasoning tasks, and with a common core component of rule induction. Previous studies have demonstrated that different strategies are adopted in number series and letter series completion tasks; even the underlying rules are identical. In the present study, we examined cortical activation as a function of two different reasoning strategies for solving series completion tasks. The retrieval strategy, used in number series completion tasks, involves direct retrieving of arithmetic knowledge to get the relations between items. The procedural strategy, used in letter series completion tasks, requires counting a certain number of times to detect the relations linking two items. The two strategies require essentially the equivalent cognitive processes, but have different working memory demands (the procedural strategy incurs greater demands). The procedural strategy produced significant greater activity in areas involved in memory retrieval (dorsolateral prefrontal cortex, DLPFC) and mental representation/maintenance (posterior parietal cortex, PPC). An ACT-R model of the tasks successfully predicted behavioral performance and BOLD responses. The present findings support a general-purpose dual-process theory of inductive reasoning regarding the cognitive architecture. Copyright © 2014 Elsevier B.V. All rights reserved.
A usability evaluation of four commercial dental computer-based patient record systems
Thyvalikakath, Thankam P.; Monaco, Valerie; Thambuganipalle, Hima Bindu; Schleyer, Titus
2008-01-01
Background The usability of dental computer-based patient record (CPR) systems has not been studied, despite early evidence that poor usability is a problem for dental CPR system users at multiple levels. Methods The authors conducted formal usability tests of four dental CPR systems by using a purposive sample of four groups of five novice users. The authors measured task outcomes (correctly completed, incorrectly completed and incomplete) in each CPR system while the participants performed nine clinical documentation tasks, as well as the number of usability problems identified in each CPR system and their potential relationship to task outcomes. The authors reviewed the software application design aspects responsible for these usability problems. Results The range for correctly completed tasks was 16 to 64 percent, for incorrectly completed tasks 18 to 38 percent and for incomplete tasks 9 to 47 percent. The authors identified 286 usability problems. The main types were three unsuccessful attempts, negative affect and task incorrectly completed. They also identified six problematic interface and interaction designs that led to usability problems. Conclusion The four dental CPR systems studied have significant usability problems for novice users, resulting in a steep learning curve and potentially reduced system adoption. Clinical Implications The significant number of data entry errors raises concerns about the quality of documentation in clinical practice. PMID:19047669
Does the generation effect occur for pictures?
Kinjo, H; Snodgrass, J G
2000-01-01
The generation effect is the finding that self-generated stimuli are recalled and recognized better than read stimuli. The effect has been demonstrated primarily with words. This article examines the effect for pictures in two experiments: Subjects named complete pictures (name condition) and fragmented pictures (generation condition). In Experiment 1, memory was tested in 3 explicit tasks: free recall, yes/no recognition, and a source-monitoring task on whether each picture was complete or fragmented (the complete/incomplete task). The generation effect was found for all 3 tasks. However, in the recognition and source-monitoring tasks, the generation effect was observed only in the generation condition. We hypothesized that absence of the effect in the name condition was due to the sensory or process match effect between study and test pictures and the superior identification of pictures in the name condition. Therefore, stimuli were changed from pictures to their names in Experiment 2. Memory was tested in the recognition task, complete/incomplete task, and second source-monitoring task (success/failure) on whether each picture had been identified successfully. The generation effect was observed for all 3 tasks. These results suggest that memory of structural and semantic characteristics and of success in identification of generated pictures may contribute to the generation effect.

A growing body of literature suggests that parents socialize early-emerging prosocial behavior across varied contexts and in subtle yet powerful ways. We focus on discourse about emotions and mental states as one potential socialization mechanism given its conceptual relevance to prosocial behavior and its known positive relations with emotion understanding and social-cognitive development, as well as parents' frequent use of such discourse beginning in infancy. Specifically, we ask how parents' emotion and mental state talk (EMST) with their toddlers relates to toddlers' helping and how these associations vary by context. Children aged 18- to 30-months (n = 38) interacted with a parent during book reading and joint play with toys, two everyday contexts that afford parental discussion of emotions and mental states. Children also participated in instrumental and empathic helping tasks. Results revealed that although parents discuss mental states with their children in both contexts, the nature of their talk differs: during book reading parents labeled emotions and mental states significantly more often than during joint play, especially simple affect words (e.g., happy, sad) and explanations or elaborations of emotions; whereas they used more desire talk and mental state words (e.g., think, know) in joint play. Parents' emotion and mental state discourse related to children's empathic, emotion-based helping behavior; however, it did not relate to instrumental, action-based helping. Moreover, relations between parent talk and empathic helping varied by context: children who helped more quickly had parents who labeled emotion and mental states more often during joint play and who elicited this talk more often during book reading. As EMST both varies between contexts and exhibits context-specific associations with empathic prosocial behavior early in development, we conclude that such discourse may be a key form of socialization in emerging prosociality.
The comprehension and production of quantifiers in isiXhosa-speaking Grade 1 learners
Southwood, Frenette
2016-01-01
Background Quantifiers form part of the discourse-internal linguistic devices that children need to access and produce narratives and other classroom discourse. Little is known about the development - especially the prodiction - of quantifiers in child language, specifically in speakers of an African language. Objectives The study aimed to ascertain how well Grade 1 isiXhosa first language (L1) learners perform at the beginning and at the end of Grade 1 on quantifier comprehension and production tasks. Method Two low socioeconomic groups of L1 isiXhosa learners with either isiXhosa or English as language of learning and teaching (LOLT) were tested in February and November of their Grade 1 year with tasks targeting several quantifiers. Results The isiXhosa LOLT group comprehended no/none, any and all fully either in February or then in November of Grade 1, and they produced all assessed quantifiers in February of Grade 1. For the English LOLT group, neither the comprehension nor the production of quantifiers was mastered by the end of Grade 1, although there was a significant increase in both their comprehension and production scores. Conclusion The English LOLT group made significant progress in comprehension and production of quantifiers, but still performed worse than peers who had their L1 as LOLT. Generally, children with no or very little prior knowledge of the LOLT need either, (1) more deliberate exposure to quantifier-rich language or, (2) longer exposure to general classroom language before quantifiers can be expected to be mastered sufficiently to allow access to quantifier-related curriculum content.

The disruptive effects of pain on multitasking in a virtual errands task.
Moore, David J; Law, Anna S
2017-07-01
Pain is known to have a disruptive effect on cognitive performance, but prior studies have used highly constrained laboratory tasks that lack ecological validity. In everyday life people are required to complete more complex sets of tasks, prioritising task completion and recalling lists of tasks which need to be completed, and these tasks continue to be attempted during episodes or states of pain. The present study therefore examined the impact of thermal induced pain on a simulated errand task. Fifty-five healthy adults (36 female) performed the Edinburgh Virtual Errands Task (EVET) either during a painful thermal sensation or with no concurrent pain. Participants also completed the Experience of Cognitive Intrusion of Pain (ECIP) questionnaire to measure their self-reported cognitive impact of pain in general life. Participants who completed the EVET task in pain and who self-reported high intrusion of pain made significantly more errors than those who reported lower intrusion on the ECIP. Findings here support the growing literature that suggests that pain has a significant impact on cognitive performance. Furthermore, these findings support the developing literature suggesting that this relationship is complex when considering real world cognition, and that self-report on the ECIP relates well to performance on a task designed to reflect the complexities of everyday living. If extrapolated to chronic pain populations, these data suggest that pain during complex multitasking performance may have a significant impact on the number of errors made. For people highly vulnerable to cognitive intrusion by pain, this may result in errors such as selecting the wrong location or item to perform tasks, or forgetting to perform these tasks at the correct time. If these findings are shown to extend to chronic pain populations then occupational support to manage complex task performance, using for example diaries/electronic reminders, may help to improve everyday abilities.

Time crawls when you're not having fun: feeling entitled makes dull tasks drag on.
O'Brien, Edward H; Anastasio, Phyllis A; Bushman, Brad J
2011-10-01
All people have to complete dull tasks, but individuals who feel entitled may be more inclined to perceive them as a waste of their "precious" time, resulting in the perception that time drags. This hypothesis was confirmed in three studies. In Study 1, participants with higher trait entitlement (controlling for related variables) thought dull tasks took longer to complete; no link was found for fun tasks. In Study 2, participants exposed to entitled messages thought taking a dull survey was a greater waste of time and took longer to complete. In Study 3, participants subliminally exposed to entitled words thought dull tasks were less interesting, thought they took longer to complete, and walked away faster when leaving the laboratory. Like most resources, time is a resource valued more by entitled individuals. A time-entitlement link provides novel insight into mechanisms underlying self-focus and prosocial dynamics.

2018-01-01
Natural Language Processing - Patient Information Extraction for Researchers (NLP-PIER) was developed for clinical researchers for self-service Natural Language Processing (NLP) queries with clinical notes. This study was to conduct a user-centered analysis with clinical researchers to gain insight into NLP-PIER's usability and to gain an understanding of the needs of clinical researchers when using an application for searching clinical notes. Clinical researcher participants (n=11) completed tasks using the system's two existing search interfaces and completed a set of surveys and an exit interview. Quantitative data including time on task, task completion rate, and survey responses were collected. Interviews were analyzed qualitatively. Survey scores, time on task and task completion proportions varied widely. Qualitative analysis indicated that participants found the system to be useful and usable in specific projects. This study identified several usability challenges and our findings will guide the improvement of NLP-PIER 's interfaces.

Students in grades 5 to 9 (ages 10 to 14; 6 girls, 27 boys) who had persisting specific learning disabilities in transcription (handwriting and spelling) completed three kinds of composition tasks requiring translation (thought to written language) on iPads using alternating transcription modes (stylus or keyboard) across every three lessons: personal narratives (6 lessons) and written summaries about read source material (integrated reading-writing) and heard source material (integrated listening-writing) (12 lessons). Before composing summaries, students clicked sequentially one at a time onto translation strategies, which they read and heard through earphones, and could click on again as needed during summary writing: (a) Level I composing of the very next sentence, and (b) Level II composing of a higher-level discourse structure. ANOVAs showed that Level I strategies were used significantly more often than Level II strategies; but the main effect for transcription mode was not significant. Written summaries of read source material had more errors in main ideas and factual details than heard source materials, but not more irrelevant statements. Applications of results are discussed for using computers for writing instruction, not just accommodations, for students with persisting transcription disabilities. PMID:28670103
The Phonetics and Phonology of the Polish Calling Melodies.
Arvaniti, Amalia; Żygis, Marzena; Jaskuła, Marek
2016-01-01
Two calling melodies of Polish were investigated, the routine call, used to call someone for an everyday reason, and the urgent call, which conveys disapproval of the addressee's actions. A Discourse Completion Task was used to elicit the two melodies from Polish speakers using twelve names from one to four syllables long; there were three names per syllable count, and speakers produced three tokens of each name with each melody. The results, based on eleven speakers, show that the routine calling melody consists of a low F0 stretch followed by a rise-fall-rise; the urgent calling melody, on the other hand, is a simple rise-fall. Systematic differences were found in the scaling and alignment of tonal targets: the routine call showed late alignment of the accentual pitch peak, and in most instances lower scaling of targets. The accented vowel was also affected, being overall louder in the urgent call. Based on the data and comparisons with other Polish melodies, we analyze the routine call as LH* !H-H% and the urgent call as H* L-L%. We discuss the results and our analysis in light of recent findings on calling melodies in other languages, and explore their repercussions for intonational phonology and the modeling of intonation. © 2017 S.

Cognitive Modeling of Individual Variation in Reference Production and Comprehension

A challenge for most theoretical and computational accounts of linguistic reference is the observation that language users vary considerably in their referential choices. Part of the variation observed among and within language users and across tasks may be explained from variation in the cognitive resources available to speakers and listeners. This paper presents a computational model of reference production and comprehension developed within the cognitive architecture ACT-R. Through simulations with this ACT-R model, it is investigated how cognitive constraints interact with linguistic constraints and features of the linguistic discourse in speakers’ production and listeners’ comprehension of referring expressions in specific tasks, and how this interaction may give rise to variation in referential choice. The ACT-R model of reference explains and predicts variation among language users in their referential choices as a result of individual and task-related differences in processing speed and working memory capacity. Because of limitations in their cognitive capacities, speakers sometimes underspecify or overspecify their referring expressions, and listeners sometimes choose incorrect referents or are overly liberal in their interpretation of referring expressions.

This study of group process was motivated by a high-fidelity flight simulator project in which aircrew performance was found to be better when the crew had recently flown together. Considering recent operating experience as a group-level input factor, aspects of the communication process between crewmembers (Captain and First Officer), were explored as a possible mediator to performance. Communication patterns were defined by a speech act typology adapted for the flightdeck setting and distinguished crews that had previously flown together (FT) from those that had not flown together (NFT). A more open communication channel with respect to information exchange and validation and greater First Officer participation in task-related topics was shown by FT crews while NFT crews engaged in more non-task discourse, a speech mode less structured by roles and probably serving a more interpersonal function. Relationships between the speech categories themselves, representing linguistic, and role-related interdependencies provide guidelines for interpreting the primary findings.
Impact of police body armour and equipment on mobility.
Dempsey, Paddy C; Handcock, Phil J; Rehrer, Nancy J
2013-11-01
Body armour is used widely by law enforcement and other agencies but has received mixed reviews. This study examined the influence of stab resistant body armour (SRBA) and mandated accessories on physiological responses to, and the performance of, simulated mobility tasks. Fifty-two males (37 ± 9.2 yr, 180.7 ± 6.1 cm, 90.2 ± 11.6 kg, VO2max 50 ± 8.5 ml kg(-1) min(-1), BMI 27.6 ± 3.1, mean ± SD) completed a running VO2max test and task familiarisation. Two experimental sessions were completed (≥4 days in between) in a randomised counterbalanced order, one while wearing SRBA and appointments (loaded) and one without additional load (unloaded). During each session participants performed five mobility tasks: a balance task, an acceleration task that simulated exiting a vehicle, chin-ups, a grappling task, and a manoeuvrability task. A 5-min treadmill run (zero-incline at 13 km·h(-1), running start) was then completed. One min after the run the five mobility tasks were repeated. There was a significant decrease in performance during all tasks with loading (p < 0.001). Participants were off-balance longer; slower to complete the acceleration, grapple and mobility tasks; completed fewer chin-ups; and had greater physiological cost (↑ %HRmax, ↑ %VO2max, ↑ RER) and perceptual effort (↑ RPE) during the 5-min run. Mean performance decreases ranged from 13 to 42% while loaded, with further decreases of 6-16% noted after the 5-min run. Unloaded task performance was no different between phases. Wearing SRBA and appointments significantly reduced mobility during key task elements and resulted in greater physiological effort. These findings could have consequences for optimal function in the working environment and therefore officer and public safety. Copyright © 2013 Elsevier Ltd and The Ergonomics Society.

The fate of completed intentions.
Anderson, Francis T; Einstein, Gilles O
2017-04-01
The goal of this research was to determine whether and how people deactivate prospective memory (PM) intentions after they have been completed. One view proposes that PM intentions can be deactivated after completion, such that they no longer come to mind and interfere with current tasks. Another view is that now irrelevant completed PM intentions exhibit persisting activation, and continue to be retrieved. In Experiment 1, participants were given a PM intention embedded within the ongoing task during Phase 1, after which participants were told either that the PM task had been completed or suspended until later. During Phase 2, participants were instructed to perform only the ongoing task and were periodically prompted to report their thoughts. Critically, the PM targets from Phase 1 reappeared in Phase 2. All of our measures, including thoughts reported about the PM task, supported the existence of persisting activation. In Experiment 2, we varied conditions that were expected to mitigate persisting activation. Despite our best attempts to promote deactivation, we found evidence for the persistence of spontaneous retrieval in all groups after intentions were completed. The theoretical and practical implications of this potential dark side to spontaneous retrieval are discussed.

Capitalist Discourse, Subjectivity and Lacanian Psychoanalysis
Vanheule, Stijn
2016-01-01
This paper studies how subjectivity in capitalist culture can be characterized. Building on Lacan's later seminars XVI, XVII, XVIII, and XIX, the author first outlines Lacan's general discourse theory, which includes four characteristic discourses: the discourse of the master, the discourse of the university, the discourse of the hysteric and the discourse of the analyst. Next, the author explores the subjectivity and the mode of dealing with jouissance and semblance, which is entailed in a fifth type of discourse, the capitalist discourse, discussed by Lacan (1972). Indeed, like the other discourses that Lacan discerns, the discourse of the capitalist can be thought of as a mode of dealing with the sexual non-rapport. It is argued that in the case of neurosis the discourse of the capitalist functions as an attempt to ignore the sexual non-rapport and the dimension of the unconscious. Psychosis, by contrast, is marked by an a priori exclusion from discourse. In that case, consumerist ways of relating to the other might offer a semblance, and thus the possibility of inventing a mode of relating to the other. Two clinical vignettes are presented to illustrate this perspective: one concerning the neurotic structure and one concerning the psychotic structure. PMID:28018280

Health care systems increasingly rely on patients' data entry efforts to organize and assist in care delivery through health information exchange. We sought to determine (1) the variation in burden imposed on parents by data entry efforts across paper-based and computer-based environments, and (2) the impact, if any, of parents' health literacy on the task burden. We completed a randomized controlled trial of parent-completed data entry tasks. Parents of children with attention deficit hyperactivity disorder (ADHD) were randomized based on the Test of Functional Health Literacy in Adults (TOFHLA) to either a paper-based or computer-based environment for entry of health information on their children. The primary outcome was the National Aeronautics and Space Administration Task Load Index (TLX) total weighted score. We screened 271 parents: 194 (71.6%) were eligible, and 180 of these (92.8%) constituted the study cohort. We analyzed 90 participants from each arm. Parents who completed information tasks on paper reported a higher task burden than those who worked in the computer environment: mean (SD) TLX scores were 22.8 (20.6) for paper and 16.3 (16.1) for computer. Assignment to the paper environment conferred a significant risk of higher task burden (F(1,178) = 4.05, P = .046). Adequate literacy was associated with lower task burden (decrease in burden score of 1.15 SD, P = .003). After adjusting for relevant child and parent factors, parents' TOFHLA score (beta = -.02, P = .02) and task environment (beta = .31, P = .03) remained significantly associated with task burden. A tailored computer-based environment provided an improved task experience for data entry compared to the same tasks completed on paper. Health literacy was inversely related to task burden.

This research studies the neural systems underlying two integration processes that take place during natural discourse comprehension: consistency evaluation and passive comprehension. Evaluation was operationalized with a consistency judgment task and passive comprehension with a passive listening task. Using fMRI, the experiment examined the integration of incoming sentences with more recent, local context and with more distal, global context in these two tasks. The stimuli were stories in which we manipulated the consistency of the endings with the local context and the relevance of the global context for the integration of the endings. A whole-brain analysis revealed several differences between the two tasks. Two networks previously associated with semantic processing and attention orienting showed more activation during the judgment than the passive listening task. A network previously associated with episodic memory retrieval and construction of mental scenes showed greater activity when global context was relevant, but only during the judgment task. This suggests that evaluation, more than passive listening, triggers the reinstantiation of global context and the construction of a rich mental model for the story. Finally, a network previously linked to fluent updating of a knowledge base showed greater activity for locally consistent endings than inconsistent ones, but only during passive listening, suggesting a mode of comprehension that relies on a local scope approach to language processing. Taken together, these results show that consistency evaluation and passive comprehension weigh differently on distal and local information and are implemented, in part, by different brain networks.

Formalized Epistemology, Logic, and Grammar
NASA Astrophysics Data System (ADS)
Bitbol, Michel
The task of a formal epistemology is defined. It appears that a formal epistemology must be a generalization of "logic" in the sense of Wittgenstein's Tractatus. The generalization is required because, whereas logic presupposes a strict relation between activity and language, this relation may be broken in some domains of experimental enquiry (e.g., in microscopic physics). However, a formal epistemology should also retain a major feature of Wittgenstein's "logic": It must not be a discourse about scientific knowledge, but rather a way of making manifest the structures usually implicit in knowledge-gaining activity. This strategy is applied to the formalism of quantum mechanics.

There is currently limited research evaluating planning abilities, a core subcomponent of executive functioning, in individuals with mild cognitive impairment (MCI). In the present study, we utilized the "Amap Task," an open-ended problem-solving task, to separately evaluate the formulation and execution components of planning ability in individuals with MCI. Thirty-seven cognitively healthy older adults and 37 individuals with MCI used a map layout of a university apartment to develop and write out a strategy (formulation stage) to successfully complete a list of tasks (e.g., retrieve and fill a water pitcher before placing it in the refrigerator). Subsequently, participants carried out the tasks in the apartment with the aid of their formulated plan (execution stage). MCI participants performed more poorly than older adult (OA) controls during both the formulation and execution stages on measures of task accuracy and task efficiency. However, both groups were able to adjust and improve task accuracy and efficiency from formulation to task execution. Finally, MCI participants took significantly longer to complete the task and adhered less to their formulated plans during task completion. Using an open-ended problem-solving task, the findings revealed that individuals with MCI experienced difficulties with both the formulation and execution components of planning. Like controls, participants with MCI were able to successfully modify their plan online, improving their performance from task formulation to task execution.

This study evaluates whether surgical experience influences technical competence using the Flinders sinus surgery simulator, a virtual environment designed to teach nasal endoscopic surgical skills. Ten experienced sinus surgeons (five consultants and five registrars) and 14 novices (seven resident medical officers and seven interns/medical students) completed three simulation tasks using haptic controllers. Task 1 required navigation of the sinuses and identification of six anatomical landmarks, Task 2 required removal of unhealthy tissue while preserving healthy tissue and Task 3 entailed backbiting within pre-set lines on the uncinate process and microdebriding tissue between the cuts. Novices were compared with experts on a range of measures, using Mann-Whitney U -tests. Novices took longer on all tasks (Task 1: 278%, P < 0.005; Task 2: 112%, P < 0.005; Task 3: 72%, P < 0.005). In Task 1, novices' instruments travelled further than experts' (379%, P < 0.005), and provided greater maximum force (12%, P < 0.05). In Tasks 2 and 3 novices performed more cutting movements to remove the tissue (Task 2: 1500%, P < 0.005; Task 3: 72%, P < 0.005). Experts also completed more of Task 3 (66%, P < 0.05). The study demonstrated the Flinders sinus simulator's construct validity, differentiating between experts and novices with respect to procedure time, instrument distance travelled and number of cutting motions to complete the task. © 2015 Royal Australasian College of Surgeons.

To define the time needed by urology residents to attain proficiency in computer-aided robotic surgery to aid in the refinement of a robotic surgery simulation curriculum. We undertook a retrospective review of robotic skills training data acquired during January 2012 to December 2014 from junior (postgraduate year [PGY] 2-3) and senior (PGY4-5) urology residents using the da Vinci Skills Simulator. We determined the number of training sessions attended and the level of proficiency achieved by junior and senior residents in attempting 11 basic or 6 advanced tasks, respectively. Junior residents successfully completed 9.9 ± 1.8 tasks, with 62.5% completing all 11 basic tasks. The maximal cumulative success rate of junior residents completing basic tasks was 89.8%, which was achieved within 7.0 ± 1.5 hours of training. Of senior residents, 75% successfully completed all six advanced tasks. Senior residents attended 6.3 ± 3.5 hours of training during which 5.1 ± 1.6 tasks were completed. The maximal cumulative success rate of senior residents completing advanced tasks was 85.4%. When designing and implementing an effective robotic surgical training curriculum, an allocation of 10 hours of training may be optimal to allow junior and senior residents to achieve an acceptable level of surgical proficiency in basic and advanced robotic surgical skills, respectively. These data help guide the design and scheduling of a residents training curriculum within the time constraints of a resident's workload.
Eye Movement Evidence for Hierarchy Effects on Memory Representation of Discourses.
Wu, Yingying; Yang, Xiaohong; Yang, Yufang
2016-01-01
In this study, we applied the text-change paradigm to investigate whether and how discourse hierarchy affected the memory representation of a discourse. Three kinds of three-sentence discourses were constructed. In the hierarchy-high condition and the hierarchy-low condition, the three sentences of the discourses were hierarchically organized and the last sentence of each discourse was located at the high level and the low level of the discourse hierarchy, respectively. In the linear condition, the three sentences of the discourses were linearly organized. Critical words were always located at the last sentence of the discourses. These discourses were successively presented twice and the critical words were changed to semantically related words in the second presentation. The results showed that during the early processing stage, the critical words were read for longer times when they were changed in the hierarchy-high and the linear conditions, but not in the hierarchy-low condition. During the late processing stage, the changed-critical words were again found to induce longer reading times only when they were in the hierarchy-high condition. These results suggest that words in a discourse have better memory representation when they are located at the higher rather than at the lower level of the discourse hierarchy. Global discourse hierarchy is established as an important factor in constructing the mental representation of a discourse.

Mind wandering and retrieval from episodic memory: a pilot event-related potential study.
Riby, Leigh Martin; Smallwood, Jonathan; Gunn, Valerie P
2008-06-01
The present study investigated the effects of mind wandering (task-unrelated thought) on the subcomponents of episodic memory as reflected by event-related potentials (ERPs). Specifically, individual differences in the pattern of ERP episodic 'old/new' effects (left-parietal, right-frontal and central-negativity effects) were examined across groups of participants experiencing either high or low frequencies of task-unrelated thought during encoding. Twenty participants studied lists of words and line drawings in one of two contexts (red versus green coloured boxes). At test, participants discriminated between target (old words or line drawings presented in one colour) and nontargets (old items from the other colour and new items). On completion of the memory task, participants completed the 'thinking' component of the Dundee Stress State Questionnaire to provide a retrospective measure of task-unrelated thought. Behavioural data indicated that irrespective of the presence of task-unrelated thought, participants were able to complete the memory task equally well. However, an analysis of ERPs across High and Low task-unrelated thought groups revealed differences in retrieval strategy. Those individuals with infrequent episodes of task-unrelated thought at study used a 'pure' recollection strategy (left-parietal effect only). Conversely, those participants experiencing frequent episodes of task-unrelated thought were unable to recollect the stimuli with ease, as indexed by a diminished parietal effect. As a consequence, these participants employed additional strategic processes for task completion, as indexed by an elevated amplitude of central negativity effects. These data are consistent with the decoupling hypothesis of mind wandering which suggests impaired recollection when attention becomes directed away from the task.

The conflicting influences of religiosity on attitude toward torture.
Malka, Ariel; Soto, Christopher J
2011-08-01
This research examines the thesis that religiosity has conflicting influences on Americans' attitudes about the use of torture on terrorism suspects: an organic influence favoring opposition to torture and a discursively driven influence favoring support of torture. In each of two national samples, religiosity had both a direct effect toward opposition to torture and an indirect effect-via conservative political alignment-toward support of torture. Multiple-group analyses revealed that the direct effect toward opposition to torture did not vary across Americans with differing levels of exposure to political discourse, whereas the indirect effect toward support of torture via conservative political alignment was much stronger among Americans highly exposed to political discourse. Among such individuals, the indirect effect was so strong that it completely counteracted the competing direct effect. Discussion focuses on the competing influences that a single nonpolitical psychological characteristic may have on a political preference.
Biological Discourses on Human Races and Scientific Racism in Brazil (1832-1911).
Arteaga, Juanma Sánchez
2017-05-01
This paper analyzes biological and scientific discourses about the racial composition of the Brazilian population, between 1832 and 1911. The first of these dates represents Darwin's first arrival in the South-American country during his voyage on H.M.S. Beagle. The study ends in 1911, with the celebration of the First universal Races congress in London, where the Brazilian physical anthropologist J.B. Lacerda predicted the complete extinction of black Brazilians by the year 2012. Contemporary European and North-American racial theories had a profound influence in Brazilian scientific debates on race and miscegenation. These debates also reflected a wider political and cultural concern, shared by most Brazilian scholars, about the future of the Nation. With few known exceptions, Brazilian evolutionists, medical doctors, physical anthropologists, and naturalists, considered that the racial composition of the population was a handicap to the commonly shared nationalistic goal of creating a modern and progressive Brazilian Republic.
Negotiating competing discourses in narratives of midwifery leadership in the English NHS.
Divall, Bernie
2015-11-01
to explore midwifery leaders' narratives of identity, within the context of one region of England. a qualitative study using narrative identity theory. Data were collected using in-depth, loosely structured narrative interviews. the study was undertaken in the Midlands region of England, in the context of a midwifery-specific leadership development programme. Participants were located in local NHS organisations and higher education institutions. the interviewees were midwives currently in one of a variety of formal leadership roles, who had recently completed a midwifery leadership development programme. Nine leaders were interviewed for the study. two central themes emerged: 'I am still a midwife' showed interviewees' continued self-identification according to their professional identity, despite the majority no longer holding a clinical role; 'Between a rock and a hard place' showed the challenges of maintaining a professionally-based identity narrative in the face of group and organisational discourses. among the midwifery leaders interviewed, narratives centred on a continued midwife self-identification. However, participants faced a number of challenges in maintaining this narrative, within the context of wider professional group and organisational discourses. midwifery leaders require the support of their professional group and organisational structures if they are to maintain a positive self- and social-identity.

Sort-Mid tasks scheduling algorithm in grid computing.
Reda, Naglaa M; Tawfik, A; Marzok, Mohamed A; Khamis, Soheir M
2015-11-01
Scheduling tasks on heterogeneous resources distributed over a grid computing system is an NP-complete problem. The main aim for several researchers is to develop variant scheduling algorithms for achieving optimality, and they have shown a good performance for tasks scheduling regarding resources selection. However, using of the full power of resources is still a challenge. In this paper, a new heuristic algorithm called Sort-Mid is proposed. It aims to maximizing the utilization and minimizing the makespan. The new strategy of Sort-Mid algorithm is to find appropriate resources. The base step is to get the average value via sorting list of completion time of each task. Then, the maximum average is obtained. Finally, the task has the maximum average is allocated to the machine that has the minimum completion time. The allocated task is deleted and then, these steps are repeated until all tasks are allocated. Experimental tests show that the proposed algorithm outperforms almost other algorithms in terms of resources utilization and makespan.

A temporary deficiency in self-control: Can heightened motivation overcome this effect?
Kelly, Claire L; Crawford, Trevor J; Gowen, Emma; Richardson, Kelly; Sünram-Lea, Sandra I
2017-05-01
Self-control is important for everyday life and involves behavioral regulation. Self-control requires effort, and when completing two successive self-control tasks, there is typically a temporary drop in performance in the second task. High self-reported motivation and being made self-aware somewhat counteract this effect-with the result that performance in the second task is enhanced. The current study explored the relationship between self-awareness and motivation on sequential self-control task performance. Before employing self-control in an antisaccade task, participants initially applied self-control in an incongruent Stroop task or completed a control task. After the Stroop task, participants unscrambled sentences that primed self-awareness (each started with the word "I") or unscrambled neutral sentences. Motivation was measured after the antisaccade task. Findings revealed that, after exerting self-control in the incongruent Stroop task, motivation predicted erroneous responses in the antisaccade task for those that unscrambled neutral sentences, and high motivation led to fewer errors. Those primed with self-awareness were somewhat more motivated overall, but motivation did not significantly predict antisaccade performance. Supporting the resource allocation account, if one was motivated-intrinsically or via the manipulation of self-awareness-resources were allocated to both tasks leading to the successful completion of two sequential self-control tasks. © 2017 The Authors.

Using a Dialogical Approach to Examine Peer Feedback During Chemistry Investigative Task Discussion

Peer feedback is an inherent feature of classroom collaborative learning. Students invariably turn to their peers for feedback when carrying out an investigative task, and this feedback is usually implicit, unstructured and may positively or negatively influence students' learning when they work on a task. This study explored the characteristics of verbal peer feedback during a collaborative investigative chemistry task involving New Zealand Year 13 students. During the planning stage of the students' investigation, the discussions of five pairs of students were recorded and then transcribed. Analysis of transcribed verbal data focused on interactions that involved peer feedback along two dimensions, interactive/non-interactive and dialogic/authoritative (Mortimer and Scott, 2003). The findings indicated that although students adopted a predominantly interactive/authoritative communicative approach, with peer feedback as confirmation or evaluation, they are also capable of a more interactive/dialogic exchange, characterised by elaborative peer feedback. We discuss how this dialogic perspective on peer feedback provides an alternative approach to the analysis and study of student-student interactions during science investigations. The findings should be interpreted in light of the limitations in terms of sample size, grouping and specificity of the coding scheme. Implications for teacher practice are discussed in relation to facilitating peer feedback discourse in the science classroom.

The goal of this study was to design and implement a novel surgical telementoring system called the System for Telementoring with Augmented Reality (STAR) that uses a virtual transparent display to convey precise locations in the operating field to a trainee surgeon. This system was compared with a conventional system based on a telestrator for surgical instruction. A telementoring system was developed and evaluated in a study which used a 1 × 2 between-subjects design with telementoring system, that is, STAR or conventional, as the independent variable. The participants in the study were 20 premedical or medical students who had no prior experience with telementoring. Each participant completed a task of port placement and a task of abdominal incision under telementoring using either the STAR or the conventional system. The metrics used to test performance when using the system were placement error, number of focus shifts, and time to task completion. When compared with the conventional system, participants using STAR completed the 2 tasks with less placement error (45% and 68%) and with fewer focus shifts (86% and 44%), but more slowly (19% for each task). Using STAR resulted in decreased annotation placement error, fewer focus shifts, but greater times to task completion. STAR placed virtual annotations directly onto the trainee surgeon's field of view of the operating field by conveying location with great accuracy; this technology helped to avoid shifts in focus, decreased depth perception, and enabled fine-tuning execution of the task to match telementored instruction, but led to greater times to task completion.

Motion as motivation: using repetitive flexion movements to stimulate the approach system.
Haeffel, Gerald J
2011-12-01
Research suggests that having a healthy approach system is critical for adaptive emotional functioning. The goal of the current study (n=186 undergraduates) was to determine the efficacy of an easy-to-disseminate and cost-efficient strategy for stimulating this system. The experiment tested the effects of repeated flexion movements (rFM) on approach system activation as measured by both self-report (BAS scales) and behavior. The results showed that rFM increased approach system motivation in men but not women. Men who completed the rFM task reported significantly greater levels of fun-seeking motivation than men in the control task. Moreover, the rFM task led to changes in actual behavior. Men who completed the rFM task exhibited significantly greater persistence on a difficult laboratory task than men in the control task. In contrast, women who completed the rFM task reported significantly lower levels of fun seeking and tended to exhibit less persistence on a difficult laboratory task than women in the control task. These results provide support for embodied theories of emotion as well as additional evidence for a gender difference in approach-avoidance tendencies. Copyright © 2011. Published by Elsevier Ltd.
An emerging discourse: toward epistemic diversity in nursing.
Georges, Jane M
2003-01-01
Grounded in a postmodern feminist methodology, this article undertakes an initial analysis of a newly emerging discourse in contemporary nursing academia in the United States. Two currently prominent discourses in nursing, a dominant discourse informed by the processes and values of "science" in the Enlightenment sense and a concurrent marginalized discourse informed by postmodernism, are described as a context for the emerging discourse. A genealogy informed by the work of Foucault is presented as a basis for an analysis of the power effects resulting from the conflict between these 2 discourses. Finally, 3 recent texts in nursing are analyzed and common themes identified as indicative of a new intertextual discourse, termed "epistemic diversity," emerging from this discursive conflict.
Model construction of “earning money by taking photos”
NASA Astrophysics Data System (ADS)
Yang, Jingmei
2018-03-01
In the era of information, with the increasingly developed network, “to earn money by taking photos” is a self-service model under the mobile Internet. The user downloads the APP, registers as a member of the APP, and then takes a task that needs to take photographs from the APP and earns the reward of the task on the APP. The article uses the task data and membership information data of an already completed project, including the member’s location and reputation value. On the basis of reasonable assumption, the data was processed with the MATLAB, SPSS and Excel software. This article mainly studied problems of the function relationship between the task performance, task position (GPS latitude and GPS longitude) and task price of users, analyzed the project’s task pricing rules and the reasons why the task is not completed, and applied multivariate regression function and GeoQ software to analyze the data, studied the task pricing rules, applied the chart method to solve the complex data, clear and easy to understand, and also reality simulation is applied to analyze why the tasks are not completed. Also, compared with the previous program, a new task pricing program is designed for the project to obtain the confidence level by means of the SPSS software, to estimate the reasonable range of the task pricing, predict and design a new pricing program on the reasonable price range.
The importance of causal connections in the comprehension of spontaneous spoken discourse.
Cevasco, Jazmin; van den Broek, Paul
2008-11-01
In this study, we investigated the psychological processes in spontaneous discourse comprehension through a network theory of discourse representation. Existing models of narrative comprehension describe the importance of causality processing for forming a representation of a text, but usually in the context of deliberately composed texts rather than in spontaneous, unplanned discourse. Our aim was to determine whether spontaneous discourse components with many causal connections are represented more strongly than components with few connections--similar to the findings in text comprehension literature--and whether any such effects depend on the medium in which the spontaneous discourse is presented (oral vs. written). Participants either listened to or read a transcription of a section of a radio transmission. They then recalled the spontaneous discourse material and answered comprehension questions. Results indicate that the processing of causal connections plays an important role in the comprehension of spontaneous spoken discourse, and do not indicate that their effects on recall are weaker in the comprehension of oral discourse than in the comprehension of written discourse.
Does order matter? Investigating the effect of sequence on glance duration during on-road driving
Roberts, Shannon C.; Reimer, Bryan; Mehler, Bruce
2017-01-01
Previous literature has shown that vehicle crash risks increases as drivers’ off-road glance duration increases. Many factors influence drivers’ glance duration such as individual differences, driving environment, or task characteristics. Theories and past studies suggest that glance duration increases as the task progresses, but the exact relationship between glance sequence and glance durations is not fully understood. The purpose of this study was to examine the effect of glance sequence on glance duration among drivers completing a visual-manual radio tuning task and an auditory-vocal based multi-modal navigation entry task. Eighty participants drove a vehicle on urban highways while completing radio tuning and navigation entry tasks. Forty participants drove under an experimental protocol that required three button presses followed by rotation of a tuning knob to complete the radio tuning task while the other forty participants completed the task with one less button press. Multiple statistical analyses were conducted to measure the effect of glance sequence on glance duration. Results showed that across both tasks and a variety of statistical tests, glance sequence had inconsistent effects on glance duration—the effects varied according to the number of glances, task type, and data set that was being evaluated. Results suggest that other aspects of the task as well as interface design effect glance duration and should be considered in the context of examining driver attention or lack thereof. All in all, interface design and task characteristics have a more influential impact on glance duration than glance sequence, suggesting that classical design considerations impacting driver attention, such as the size and location of buttons, remain fundamental in designing in-vehicle interfaces.

Direct real-time neural evidence for task-set inertia.
Evans, Lisa H; Herron, Jane E; Wilding, Edward L
2015-03-01
One influential explanation for the costs incurred when switching between tasks is that they reflect interference arising from completing the previous task-known as task-set inertia. We report a novel approach for assessing task-set inertia in a memory experiment using event-related potentials (ERPs). After a study phase, participants completed a test block in which they switched between a memory task (retrieving information from the study phase) and a perceptual task. These tasks alternated every two trials. An ERP index of the retrieval of study information was evident in the memory task. It was also present on the first trial of the perceptual task but was markedly attenuated on the second. Moreover, this task-irrelevant ERP activity was positively correlated with a behavioral cost associated with switching between tasks. This real-time measure of neural activity thus provides direct evidence of task-set inertia, its duration, and the functional role it plays in switch costs. © The Author(s) 2015.
[Textual research on the time of completion of XU Shuwei' books on exo-pathogenic cold diseases].
Lu, Mingxin
2015-11-01
Shang han bai zheng ge (Poets of Syndromes of Exo-pathogenic Cold Disease), Shang han fa wei lun (Discourse on Elucidation of Exo-pathogenic Cold Disease), Shang han jiu shi lun (90 Discourses on Exo-pathogenic Cold Disease) were the three extant books on exo-pathogenic cold disease written by Xu Shuwei among his other works of its kind. Although there were carved editions of the Yuan and Ming Dynasties, these books were gradually paid attention for citations by other physicians till the Qing Dynasty. Through comparison of its texts, it can be found that the title of Shang han bai zheng ge was mentioned in his other medical works. While Shang han fa wei lun and Shang han jiu shi lun contained some overlapping contents, some even carrying concept contradictory to each other. According to historical materials, Xu Shuwei began to write the above-mentioned 3 books in the Northern Song Dynasty. In the several early years of the Southern Song Dynasty after crossing the Yangtze River, he collected the remained manuscripts and continued to write. Among them, Shang han bai zheng ge was completed first, followed by Shang han fa wei lun, with Shang han jiu shi lun came as the last.
A Taiwanese Mandarin Main Concept Analysis (TM-MCA) for quantification of aphasic oral discourse.
Kong, Anthony Pak-Hin; Yeh, Chun-Chih
2015-01-01
Various quantitative systems have been proposed to examine aphasic oral narratives in English. A clinical tool for assessing discourse produced by Cantonese-speaking persons with aphasia (PWA), namely Main Concept Analysis (MCA), was developed recently for quantifying the presence, accuracy and completeness of a narrative. Similar tools for Mandarin speakers are currently absent. The first aim is to develop and establish the validity of the Taiwanese Mandarin Main Concept Analysis (TM-MCA) for the Mandarin-speaking population in Taiwan, given the paucity of related investigations. Another aim is to establish the influence of age and education level on Taiwanese Mandarin speakers' oral narrative abilities. The third purpose is to examine how well the TM-MCA could distinguish between native speakers with and without aphasia in Taiwan. The final aim is to examine the reliability and validity of the TM-MCA. Eight speech-language pathologists (SLPs) and eight neurologically intact participants were involved to establish the TM-MCA main concepts. Another 36 neurologically intact participants and 10 PWA participated to validate the TM-MCA by contrasting their performance. Both age and educational level affected the oral discourse performance among the neurologically intact adults. Significant differences on the TM-MCA measures were noted between the control group and the group with aphasia. Moreover, the degree of aphasia significantly affected the oral discourse of PWA. The TM-MCA is a culturally appropriate quantitative system for the Taiwanese Mandarin population. It can be used to supplement standardized aphasia tests to help SLPs make more informative decisions not only on clinical diagnosis but also on treatment planning. © 2015 Royal College of Speech and Language Therapists.

Effects of anxiety on task switching: evidence from the mixed antisaccade task.
Ansari, Tahereh L; Derakshan, Nazanin; Richards, Anne
2008-09-01
According to the attentional control theory of anxiety (Eysenck, Derakshan, Santos, & Calvo, 2007), anxiety impairs performance on cognitive tasks that involve the shifting function of working memory. This hypothesis was tested using a mixed antisaccade paradigm, in which participants performed single-task and mixed-task versions of the paradigm. The single task involved the completion of separate blocks of anti- and prosaccade trials, whereas in the mixed task, participants completed anti- and prosaccade trials in a random order within blocks. Analysis of switch costs showed that high-anxious individuals did not exhibit the commonly reported paradoxical improvement in saccade latency, whereas low-anxious individuals did. The findings are discussed within the framework of attentional control theory.
Student leadership in small group science inquiry

Oliveira, Alandeom W.; Boz, Umit; Broadwell, George A.; Sadler, Troy D.
2014-09-01
Background: Science educators have sought to structure collaborative inquiry learning through the assignment of static group roles. This structural approach to student grouping oversimplifies the complexities of peer collaboration and overlooks the highly dynamic nature of group activity. Purpose: This study addresses this issue of oversimplification of group dynamics by examining the social leadership structures that emerge in small student groups during science inquiry. Sample: Two small student groups investigating the burning of a candle under a jar participated in this study. Design and method: We used a mixed-method research approach that combined computational discourse analysis (computational quantification of social aspects of small group discussions) with microethnography (qualitative, in-depth examination of group discussions). Results: While in one group social leadership was decentralized (i.e., students shared control over topics and tasks), the second group was dominated by a male student (centralized social leadership). Further, decentralized social leadership was found to be paralleled by higher levels of student cognitive engagement. Conclusions: It is argued that computational discourse analysis can provide science educators with a powerful means of developing pedagogical models of collaborative science learning that take into account the emergent nature of group structures and highly fluid nature of student collaboration.
Working Memory and Speech Comprehension in Older Adults With Hearing Impairment.
Nagaraj, Naveen K
2017-10-17
This study examined the relationship between working memory (WM) and speech comprehension in older adults with hearing impairment (HI). It was hypothesized that WM would explain significant variance in speech comprehension measured in multitalker babble (MTB). Twenty-four older (59-73 years) adults with sensorineural HI participated. WM capacity (WMC) was measured using 3 complex span tasks. Speech comprehension was assessed using multiple passages, and speech identification ability was measured using recall of sentence final-word and key words. Speech measures were performed in quiet and in the presence of MTB at + 5 dB signal-to-noise ratio. Results suggested that participants' speech identification was poorer in MTB, but their ability to comprehend discourse in MTB was at least as good as in quiet. WMC did not explain significant variance in speech comprehension before and after controlling for age and audibility. However, WMC explained significant variance in low-context sentence key words identification in MTB. These results suggest that WMC plays an important role in identifying low-context sentences in MTB, but not when comprehending semantically rich discourse passages. In general, data did not support individual variability in WMC as a factor that predicts speech comprehension ability in older adults with HI.

This multiple case study examined the coauthorship process in research laboratories of different university departments. The study focused on two cases comprising five writing teams, one in biochemistry and microbiology and four in earth and ocean sciences. The role of the research supervisor, the role of the student (graduate and postgraduate), the interaction of the supervisor and the student, the activities and processes inherent in the coauthorship process, and the student's beliefs, expertise, scientific writing, and entry into an academic discourse community were documented utilizing multiple sources of data and methods. Several activities and processes were found to be common across all coauthorship teams, including aspects of planning, drafting, and revising. Elements of scientific and writing expertise, facets of enculturation into scientific research and discourse communities, academic civility, and the dynamics of collaborative groups also were apparent. There was healthy tension and mutual respect in the research groups as they attempted to make sense of science, report their results clearly and persuasively, and share the responsibilities of expertise. The novice scientists came to appreciate that the writing, editing, and revising process influenced the quality of the science as well as the writing.

While universal literacy is one of the most pervasive targets of today's educational systems, it is at the same time perhaps the narrowest of all goals. Standardised testing reduces language and literacy to tasks associated with reading and writing. As learning communities become increasingly diverse, teachers, administrators and policy makers are finding themselves in a position where in order to maximise student development they need to broaden their conceptualisations of literacy, merge curricular areas and implement inclusive practices. Addressing literacy instructors and policy makers in particular, the authors of this article present a WORLD view of literacy (Word, Orality, Re-vision, Literacies, Discourses) towards making sense of contemporary literacy research. The purpose of this paper is multi-layered in terms of theory and practice. On the philosophical and theoretical level, it is intended to extend our understanding of literacy in view of both historical conceptualisations and contemporary views of literacy. On the reflective and practical level, it offers a unique way to assess our literacy practice and re-vision what we do. Demonstrating the universality of this approach, this is illustrated by a few ideas from a poem, a children's book, a dystopian novel for teenagers and a film.

In the 19th century, fervid debates arose in the young psychiatric science about how to deal with and to scientifically categorize human behaviour which was perceived as dangerous to society, and as criminal. There were two concepts that stood out in these transnationally held discussions; namely moral insanity and later on, psychopathy. Following recent approaches in the cultural and social history of psychiatry, we understand moral insanity and psychopathy as social constructs, which are determined by the evolution in psychiatric knowledge, and also by laws, codes and social norms of particular historical timeframes. Our task is to discuss the evolution and adoption of these concepts in two linguistically different, but still historically profoundly entangled regions, namely in Italian and Croatian psychiatric discourses at the turn from the 19th to the 20th century. Our analysis of two of the most important medical and psychiatric journals of the time shows that psychiatric debates on antisocial and criminal behaviour were in numerous ways entangled and shaped by the way the two societies scientifically, legally, and institutionally struggled over the question of how to detect and control the mentally incapacitated criminal offender.
The teacher's role in promoting collaborative dialogue in the classroom.
Webb, Noreen M
2009-03-01
Research on student-led small-group learning in schools going back nearly four decades has documented many types of student participation that promote learning. Less is known about how the teacher can foster effective groupwork behaviours. This paper reviews research that explores the role of the teacher in promoting learning in small groups. The focus is on how students can learn from their peers during small-group work, how teachers can prepare students for collaborative group work, and the role of teacher discourse and classroom norms in small-group dialogue. Studies selected for review focused on student-led small-group contexts for learning in which students were expected to collaborate, reported data from systematic observations of group work, and linked observational data to teacher practices and student learning outcomes. This review uncovered multiple dimensions of the teacher's role in fostering beneficial group dialogue, including preparing students for collaborative work, forming groups, structuring the group-work task, and influencing student interaction through teachers' discourse with small groups and with the class. Common threads through the research are the importance of students explaining their thinking, and teacher strategies and practices that may promote student elaboration of ideas.

What role does socialization play in the origins of prosocial behavior? We examined one potential socialization mechanism, parents’ discourse about others’ emotions with very young children in whom prosocial behavior is still nascent. Two studies are reported, one of sharing in 18- and 24-month-olds (n = 29), and one of instrumental and empathy-based helping in 18- and 30-month-olds (n = 62). In both studies, parents read age-appropriate picture books to their children and the content and structure of their emotion-related and internal state discourse were coded. Results showed that children who helped and shared more quickly and more often, especially in tasks that required more complex emotion understanding, had parents who more often asked them to label and explain the emotions depicted in the books. Moreover, it was parents’ elicitation of children’s talk about emotions rather than parents’ own production of emotion labels and explanations that explained children’s prosocial behavior, even after controlling for age. Thus, it is the quality, not the quantity, of parents’ talk about emotions with their toddlers that matters for early prosocial behavior. PMID:23264753

Grief following child loss is profoundly destabilizing with serious long-term repercussions for bereaved parents. Employed parents may need time away from work to deal with this loss. The purpose of this study was to reflect upon the ways labour policies and practices respond to parental bereavement. Critical discourse analysis was used to examine labour policies and practices related to employment leave for bereaved parents in Canada. Results were compared to international labour standards. Universally, employment policies provide only for the practical issues of bereavement. Commonly, leave is three days, unpaid, and meant to enable ceremonial obligations. Policies do not acknowledge the long-term suffering caused by grief or the variable intensity of different kinds of loss. Managerial, moral, normative and neoliberal values embedded in these policies efface the intensely personal experience of grief, thereby leaving employees at risk for serious health and workplace safety issues. Bereavement leave currently understands grief as a generic, time-limited state with instrumental tasks and ceremonial obligations. In contrast, research characterizes responses to child loss as intense, highly personal experiences for which healing and recovery can take years. This disconnect is especially problematic when viewed through the lens of employee wellbeing, reintegration and workplace productivity.

Impact of Frequent Interruption on Nurses' Patient-Controlled Analgesia Programming Performance.
Campoe, Kristi R; Giuliano, Karen K
2017-12-01
The purpose was to add to the body of knowledge regarding the impact of interruption on acute care nurses' cognitive workload, total task completion times, nurse frustration, and medication administration error while programming a patient-controlled analgesia (PCA) pump. Data support that the severity of medication administration error increases with the number of interruptions, which is especially critical during the administration of high-risk medications. Bar code technology, interruption-free zones, and medication safety vests have been shown to decrease administration-related errors. However, there are few published data regarding the impact of number of interruptions on nurses' clinical performance during PCA programming. Nine acute care nurses completed three PCA pump programming tasks in a simulation laboratory. Programming tasks were completed under three conditions where the number of interruptions varied between two, four, and six. Outcome measures included cognitive workload (six NASA Task Load Index [NASA-TLX] subscales), total task completion time (seconds), nurse frustration (NASA-TLX Subscale 6), and PCA medication administration error (incorrect final programming). Increases in the number of interruptions were associated with significant increases in total task completion time ( p = .003). We also found increases in nurses' cognitive workload, nurse frustration, and PCA pump programming errors, but these increases were not statistically significant. Complex technology use permeates the acute care nursing practice environment. These results add new knowledge on nurses' clinical performance during PCA pump programming and high-risk medication administration.

Background Health care systems increasingly rely on patients’ data entry efforts to organize and assist in care delivery through health information exchange. Objectives We sought to determine (1) the variation in burden imposed on parents by data entry efforts across paper-based and computer-based environments, and (2) the impact, if any, of parents’ health literacy on the task burden. Methods We completed a randomized controlled trial of parent-completed data entry tasks. Parents of children with attention deficit hyperactivity disorder (ADHD) were randomized based on the Test of Functional Health Literacy in Adults (TOFHLA) to either a paper-based or computer-based environment for entry of health information on their children. The primary outcome was the National Aeronautics and Space Administration Task Load Index (TLX) total weighted score. Results We screened 271 parents: 194 (71.6%) were eligible, and 180 of these (92.8%) constituted the study cohort. We analyzed 90 participants from each arm. Parents who completed information tasks on paper reported a higher task burden than those who worked in the computer environment: mean (SD) TLX scores were 22.8 (20.6) for paper and 16.3 (16.1) for computer. Assignment to the paper environment conferred a significant risk of higher task burden (F1,178 = 4.05, P = .046). Adequate literacy was associated with lower task burden (decrease in burden score of 1.15 SD, P = .003). After adjusting for relevant child and parent factors, parents’ TOFHLA score (beta = -.02, P = .02) and task environment (beta = .31, P = .03) remained significantly associated with task burden. Conclusions A tailored computer-based environment provided an improved task experience for data entry compared to the same tasks completed on paper. Health literacy was inversely related to task burden.

Cognitive Fatigue Influences Time-On-Task during Bodyweight Resistance Training Exercise
Head, James R.; Tenan, Matthew S.; Tweedell, Andrew J.; Price, Thomas F.; LaFiandra, Michael E.; Helton, William S.
2016-01-01
Prior investigations have shown measurable performance impairments on continuous physical performance tasks when preceded by a cognitively fatiguing task. However, the effect of cognitive fatigue on bodyweight resistance training exercise task performance is unknown. In the current investigation 18 amateur athletes completed a full body exercise task preceded by either a cognitive fatiguing or control intervention. In a randomized repeated measure design, each participant completed the same exercise task preceded by a 52 min cognitively fatiguing intervention (vigilance) or control intervention (video). Data collection sessions were separated by 1 week. Participants rated the fatigue intervention with a significantly higher workload compared to the control intervention (p < 0.001). Additionally, participants self-reported significantly greater energetic arousal for cognitively fatiguing task (p = 0.02). Cognitive fatigue did not significantly impact number of repetitions completed during the exercise task (p = 0.77); however, when cognitively fatigued, participants had decreased percent time-on-task (57%) relative to the no fatigue condition (60%; p = 0.04). RPE significantly changed over time (p < 0.001), but failed to show significant differences between the cognitive fatigue intervention and control intervention (p > 0.05). There was no statistical difference for heart rate or metabolic expenditure as a function of fatigue intervention during exercise. Cognitively fatigued athletes have decreased time-on-task in bodyweight resistance training exercise tasks. PMID:27635122

The purpose of this phenomenological study was to examine the perceptions of elementary teachers who teach science as opposed to science teacher specialists regarding their efforts to help students use student-to-student discourse for improving science learning. A growing body of research confirms the importance of a) student-to-student discourse for making meaning of science ideas and b) moving students' conceptual development towards a more scientific understanding of the natural world. Based on those foundations, the three research questions that guided this study examined the value elementary teachers place on student-to-student discourse, the various approaches teachers employ to promote the use of student-to-student discourse for learning science, and the factors and conditions that promote and inhibit the use of student-to-student discourse as an effective pedagogical strategy in elementary science. Data were gathered from 23 elementary teachers in a single district using an on-line survey and follow-up interviews with 8 teachers. All data were analyzed and evolving themes led to the following findings: (1) elementary teachers value student-to-student discourse in science, (2) teachers desire to increase time using student-to-student discourse, (3) teachers use a limited number of student-to-student discourse strategies to increase student learning in science, (4) teachers use student-to-student discourse as formative assessment to determine student learning in science, (5) professional development focusing on approaches to student-to-student discourse develops teachers' capacity for effective implementation, (6) teachers perceive school administrators' knowledge of and support for student-to-student discourse as beneficial, (7) time and scheduling constraints limit the use of student-to-student discourse in science. Implications of this study included the necessity of school districts to focus on student-to-student discourse in science, provide teacher and administrator professional development regarding student-to-student discourse instructional strategies, and promote collaboration across disciplines. This study suggests that future research be conducted regarding the role of administrators in fostering student-to-student discourse, the perspectives of secondary teachers implementing student-to-student discourse, the use of student-to-student discourse in other subjects, and leadership approaches to broadening the study across districts.
On the road to DSM-V and ICD-11.
Kupfer, David J; Regier, Darrel A; Kuhl, Emily A
2008-11-01
Development of the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-V) has been ongoing since 1994, though official release will not occur for another 4 years. Potential revisions are being derived from multiple sources, including building on perceived limitations of DSM-IV; broad-based literature reviews; secondary and primary data analyses; and discussions between global members of the mental health community. The current focus on aligning DSM with the International Classification of Diseases-11 (ICD-11) speaks to the importance of creating a unified text that embraces cross-cutting issues of diagnostics, such as developmental, age-related, and cultural phenomena. International discourse is vital to this process and has been fostered by a National Institutes of Health-sponsored conference series on diagnosis-specific topics. From this series, the DSM-V Task Force developed the following set of revision principals to guide the efforts of the DSM-V Work Groups: grounding recommendations in empirical evidence; maintaining continuity with previous editions of DSM; removing a priori limitations on the amount of changes DSM-V may incur; and maintaining DSM's status as a living document. With work group formation complete, members are currently carrying out the research and revision recommendations proposed during the conference series. Ongoing activities include adding specialized advisors to each work group; completing literature reviews and planning data analyses; and forming study groups to discuss integration of cross-cutting issues (e.g., developmental lifespan factors; formation of diagnostic spectra). The road to DSM-V and ICD-11 has been challenging, but members continue to work diligently in their goal of constructing the most harmonious, scientifically sound, and clinically relevant DSM to date.
Discourse analysis: towards an understanding of its place in nursing.
Crowe, Marie
2005-07-01
This paper describes how discourse analysis, and in particular critical discourse analysis, can be used in nursing research, and provides an example to illustrate the techniques involved. Discourse analysis has risen to prominence in the 1980s and 1990s in disciplines such as the social sciences, literary theory and cultural studies and is increasingly used in nursing. This paper investigates discourse analysis as a useful methodology for conducting nursing research. Effective clinical reasoning relies on employing several different kinds of knowledge and research that draw on different perspectives, methodologies and techniques to generate breadth of knowledge and depth of understanding of clinical practices and patients' experiences of those practices. The steps in a discourse analysis include: choosing the text, and identifying the explicit purpose of the text, the processes used for claiming authority connections to other discourses, construction of major concepts, processes of naming and categorizing, construction of subject positions, construction of reality and social relations and implications for the practice of nursing. The limitations of discourse analysis, its relationship to other qualitative approaches and questions for evaluating the rigour of research using discourse analysis are also explored. The example of discourse analysis shows how a text influences the practice of nursing by shaping knowledge, values and beliefs. Discourse analysis can make a contribution to the development of nursing knowledge by providing a research strategy to examine dominant discourses that influence nursing practice.

To explore the feasibility of using a touch screen assessment tool to measure cognitive capacity in toddlers. 112 typically developing children with a median age of 31 months (IQR: 26-34) interacted with a touch screen cognitive assessment tool. We examined the sensitivity of the tool to age-related changes in cognition by comparing the number of items completed, speed of task completion and accuracy in two age groups; 24-29 months versus 30-36 months. Children aged 30-36 months completed more tasks (median: 18, IQR: 18-18) than those aged 24-29 months (median: 17, IQR: 15-18). Older children also completed two of the three working memory tasks and an object permanence task faster than their younger peers. Children became faster at completing the working memory items with each exposure and registered similar completion times on the hidden object retrieval items, despite task demands being twofold on the second exposure. A novel item required children to integrate what they had learnt on preceding items. The older group was more likely to complete this item and to do so faster than the younger group. Children as young as 24 months can complete items requiring cognitive engagement on a touch screen device, with no verbal instruction and minimal child-administrator interaction. This paves the way for using touch screen technology for language and administrator independent developmental assessment in toddlers. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

We investigated whether and how student performance on three types of spatial cognition tasks differs when worked with two-dimensional or stereoscopic representations. We recruited nineteen middle school students visiting a planetarium in a large Midwestern American city and analyzed their performance on a series of spatial cognition tasks in terms of response accuracy and task completion time. Results show that response accuracy did not differ between the two types of representations while task completion time was significantly greater with the stereoscopic representations. The completion time increased as the number of mental manipulations of 3D objects increased in the tasks. Post-interviews provide evidence that some students continued to think of stereoscopic representations as two-dimensional. Based on cognitive load and cue theories, we interpret that, in the absence of pictorial depth cues, students may need more time to be familiar with stereoscopic representations for optimal performance. In light of these results, we discuss potential uses of stereoscopic representations for science learning.
Forced Aerobic Exercise Preceding Task Practice Improves Motor Recovery Poststroke.
Linder, Susan M; Rosenfeldt, Anson B; Dey, Tanujit; Alberts, Jay L
To understand how two types of aerobic exercise affect upper-extremity motor recovery post-stroke. Our aims were to (1) evaluate the feasibility of having people who had a stroke complete an aerobic exercise intervention and (2) determine whether forced or voluntary exercise differentially facilitates upper-extremity recovery when paired with task practice. Seventeen participants with chronic stroke completed twenty-four 90-min sessions over 8 wk. Aerobic exercise was immediately followed by task practice. Participants were randomized to forced or voluntary aerobic exercise groups or to task practice only. Improvement on the Fugl-Meyer Assessment exceeded the minimal clinically important difference: 12.3, 4.8, and 4.4 for the forced exercise, voluntary exercise, and repetitive task practice-only groups, respectively. Only the forced exercise group exhibited a statistically significant improvement. People with chronic stroke can safely complete intensive aerobic exercise. Forced aerobic exercise may be optimal in facilitating motor recovery associated with task practice. Copyright © 2017 by the American Occupational Therapy Association, Inc.

Modeling discourse management compared to other classroom management styles in university physics

Desbien, Dwain Michael
2002-01-01
A classroom management technique called modeling discourse management was developed to enhance the modeling theory of physics. Modeling discourse management is a student-centered management that focuses on the epistemology of science. Modeling discourse is social constructivist in nature and was designed to encourage students to present classroom material to each other. In modeling discourse management, the instructor's primary role is of questioner rather than provider of knowledge. Literature is presented that helps validate the components of modeling discourse. Modeling discourse management was compared to other classroom management styles using multiple measures. Both regular and honors university physics classes were investigated. This style of management was found to enhance student understanding of forces, problem-solving skills, and student views of science compared to traditional classroom management styles for both honors and regular students. Compared to other reformed physics classrooms, modeling discourse classes performed as well or better on student understanding of forces. Outside evaluators viewed modeling discourse classes to be reformed, and it was determined that modeling discourse could be effectively disseminated.
Topic Structure Affects Semantic Integration: Evidence from Event-Related Potentials

2013-01-01
This study investigated whether semantic integration in discourse context could be influenced by topic structure using event-related brain potentials. Participants read discourses in which the last sentence contained a critical word that was either congruent or incongruent with the topic established in the first sentence. The intervening sentences between the first and the last sentence of the discourse either maintained or shifted the original topic. Results showed that incongruent words in topic-maintained discourses elicited an N400 effect that was broadly distributed over the scalp while those in topic-shifted discourses elicited an N400 effect that was lateralized to the right hemisphere and localized over central and posterior areas. Moreover, a late positivity effect was only elicited by incongruent words in topic-shifted discourses, but not in topic-maintained discourses. This suggests an important role for discourse structure in semantic integration, such that compared with topic-maintained discourses, the complexity of discourse structure in topic-shifted condition reduces the initial stage of semantic integration and enhances the later stage in which a mental representation is updated.

Sullivan, Florence R.; Kapur, Manu; Madden, Sandra; Shipe, Stefanie
2015-02-01
In this study, we examined whether gendered discourse styles were evidenced in online, synchronous, physics collaborative learning group discussions, and the extent to which such discourse patterns were related to the uptake of ideas within the group. We defined two discourse styles: the oppositional/direct style, theorized to be the socialized discourse pattern typically used by males, and the aligned/indirect style, theorized to be the socialized discourse pattern typically used by females. Our analysis indicates the presence of both styles in these chats and the styles were generally utilized along theorized, gendered lines. However, we also observed male use of the stereotypically 'feminine' discourse style and female use of the stereotypically 'masculine' discourse style. Moreover, we found no main effect for discourse style on the uptake of ideas. The findings indicate that, contrary to prior research in both face-to-face science classroom settings and online physics settings, ideas were taken up at relatively similar rates regardless of the gendered discourse style employed. Design implications of this study are discussed and suggestions for future research are made.

What makes up good consultations? A qualitative study of GPs' discourses.
Van Roy, Kaatje; Vanheule, Stijn; Deveugele, Myriam
2013-05-16
In medical literature, several principles that define 'good consultations' have been outlined. These principles tend to be prescriptive in nature, overlooking the complexity of general practitioners (GPs)' perspectives of everyday practice. Focusing on perspectives might be particularly relevant, since they may affect decisions and actions. Therefore, the present study adopts a bottom-up approach, analyzing GPs' narratives about 'good' and 'bad' consultations. We aimed at describing the range of discourses GPs use in relating on their practice. Semi-structured interviews were conducted with 19 Belgian GPs. By means of a qualitative analysis, the authors mapped patterns in the interview narratives and described the range of different discourses. Four discourses were identified: a biomedically-centered discourse, a communication-focused discourse, a problem-solving discourse and a satisfaction-oriented discourse. Each discourse was further specified in terms of predominant themes, problems the GPs prefer to deal with and inherent difficulties. Although most participants used elements from all four discourses, the majority of the GPs relied on an individual set of predominant discourses and focused on a limited number of themes. This study clearly indicates that there is no uniform way in which GPs perceive clinical practice. Each of the participants used a subtle mix of different criteria to define good and bad medical consultations. Some discourse elements appear to be rooted in medical literature, whereas others are of a more personal nature. By focusing on the limitations of each discourse, this study can shed new light on some of the difficulties GPs encounter in their daily practice: being confronted with specific problems might be an effect of adhering to a specific discourse. The typification of different discourses on consultations may function as a framework to help GPs reflect on how they perceive their practice, and help them manage some of the challenges met in daily practice.
Climates of risk: a field analysis of global climate change in US media discourse, 1997-2004.
Sonnett, John
2010-11-01
How are industry and environmentalist discourses of climate risk related to dominant scientific and political discourses? This study operationalizes Bourdieu's concept of symbolic capital in order to map dimensions of risk description and prescription onto a journalistic field of industry, environmentalist, scientific, and political media. Results show that conventional definitions of risk mirror an opposition between scientific and political discourses. Prescriptions for action on risk are partly autonomous from definitions however. Environmentalist and scientific media feature more proactive discourse, and industry and political media feature more reactive discourse. Implications for future research on climate risk and relational studies of media discourse are discussed.

To examine and describe disciplinary discourses conducted through professional policy and regulatory documents in nursing and midwifery in Ireland. A key tenet of discourse theory is that group identities are constructed in public discourses and these discursively-constructed identities become social realities. Professional identities can be extracted from both the explicit and latent content of discourse. Studies of nursing's disciplinary discourse have drawn attention to a dominant discourse that confers nursing with particular identities, which privilege the relational and affective aspects of nursing and in the process, marginalise scientific knowledge and the technical and body work of nursing. We used critical discourse analysis to analyse a purposive sample of nursing and midwifery regulatory and policy documents. We applied a four-part, sequential approach to analysing the selected texts. This involved identifying key words, phrases and statements that indicated dominant discourses that, in turn, revealed latent beliefs and assumptions. The focus of our analysis was on how the discourses construct professional identities. Our analysis indicated recurring narratives that appeared to confer nurses and midwives with three dominant identities: 'the knowledgeable practitioner', the 'interpersonal practitioner' and the 'accountable practitioner'. The discourse also carried assumptions about the form and content of disciplinary knowledge. Academic study of identity construction in discourse is important to disciplinary development by raising nurses' and midwives' consciousness, alerting them to the ways that their own discourse can shape their identities, influence public and political opinion and, in the process, shape public policy on their professions.

Experimentally-induced learned helplessness in adolescents with type 1 diabetes.
McLaughlin, Elizabeth; Lefaivre, Marie-josée; Cummings, Elizabeth
2010-05-01
To determine whether adolescents with type 1 diabetes are more at risk for learned helplessness than their healthy peers. Twenty-three adolescents with diabetes and 25 controls completed a solvable or unsolvable concept formation task. All completed pre- and post-task performance and attribution ratings, and later completed an anagram-solving task to determine if perceived helplessness on the first task would negatively impact performance on the second. Participants in the unsolvable condition solved fewer anagrams; those with diabetes did not show weaker performance than controls. Participants in the solvable condition (diabetes and controls) showed an increase in internal attributions from before the concept formation task to after. In the unsolvable condition, only participants with diabetes made more external attributions for their failure. Contrary to the only other controlled study to use this paradigm in youth with chronic illness, adolescents with diabetes were not more susceptible to learned helplessness.

This is an ethnographic case study of one urban high school science teacher who was attempting to use inquiry-based teaching in her practice. Rather than focusing on pedagogy, the study examines the social networks and communities of practice in which Marie Gonzalez participated. I make the argument that science teaching is a Discourse (Gee, 1990), and that teaching inquiry science means constructing an identity as a participant in what I call the Discourse of Inquiry. I also use discourse analysis to tease out a Discourse of Traditional Science Teaching. I conclude that the Traditional and Inquiry Discourses mediate a teacher's ideas of what it means to teach, and that, while Inquiry teachers are "bilingual", that is, able to participate in both Discourses, Traditional teachers are deaf to the Discourse of Inquiry. Moreover, in my study there is convincing evidence that administrators charged with evaluation were also unfamiliar with the Discourse of Inquiry and were therefore unable to provide support for Marie's inquiry practice. In light of these findings, it is not at all surprising that Marie found it quite difficult to use inquiry-based pedagogy. In order for teachers to adopt discourse-based reforms such as inquiry, the Discourse must be available to teachers in their workplaces.

Background This article considers how health services access and equity documents represent the problem of access to health services and what the effects of that representation might be for lesbian, gay, bisexual and transgender (LGBT) communities. We conducted a critical discourse analysis on selected access and equity documents using a gender-based diversity framework as determined by two objectives: 1) to identify dominant and counter discourses in health services access and equity literature; and 2) to develop understanding of how particular discourses impact the inclusion, or not, of LGBT communities in health services access and equity frameworks.The analysis was conducted in response to public health and clinical research that has documented barriers to health services access for LGBT communities including institutionalized heterosexism, biphobia, and transphobia, invisibility and lack of health provider knowledge and comfort. The analysis was also conducted as the first step of exploring LGBT access issues in home care services for LGBT populations in Ontario, Canada. Methods A critical discourse analysis of selected health services access and equity documents, using a gender-based diversity framework, was conducted to offer insight into dominant and counter discourses underlying health services access and equity initiatives. Results A continuum of five discourses that characterize the health services access and equity literature were identified including two dominant discourses: 1) multicultural discourse, and 2) diversity discourse; and three counter discourses: 3) social determinants of health (SDOH) discourse; 4) anti-oppression (AOP) discourse; and 5) citizen/social rights discourse. Conclusions The analysis offers a continuum of dominant and counter discourses on health services access and equity as determined from a gender-based diversity perspective. The continuum of discourses offers a framework to identify and redress organizational assumptions about, and ideological commitments to, sexual and gender diversity and health services access and equity. Thus, the continuum of discourses may serve as an important element of a health care organization's access and equity framework for the evaluation of access to good quality care for diverse LGBT populations. More specfically, the analysis offers four important points of consideration in relation to the development of a health services access and equity framework. PMID:21957894

When cognition kicks in: working memory and speech understanding in noise.
Rönnberg, Jerker; Rudner, Mary; Lunner, Thomas; Zekveld, Adriana A
2010-01-01
Perceptual load and cognitive load can be separately manipulated and dissociated in their effects on speech understanding in noise. The Ease of Language Understanding model assumes a theoretical position where perceptual task characteristics interact with the individual's implicit capacities to extract the phonological elements of speech. Phonological precision and speed of lexical access are important determinants for listening in adverse conditions. If there are mismatches between the phonological elements perceived and phonological representations in long-term memory, explicit working memory (WM)-related capacities will be continually invoked to reconstruct and infer the contents of the ongoing discourse. Whether this induces a high cognitive load or not will in turn depend on the individual's storage and processing capacities in WM. Data suggest that modulated noise maskers may serve as triggers for speech maskers and therefore induce a WM, explicit mode of processing. Individuals with high WM capacity benefit more than low WM-capacity individuals from fast amplitude compression at low or negative input speech-to-noise ratios. The general conclusion is that there is an overarching interaction between the focal purpose of processing in the primary listening task and the extent to which a secondary, distracting task taps into these processes.
Single-task and dual-task tandem gait test performance after concussion.
Howell, David R; Osternig, Louis R; Chou, Li-Shan
2017-07-01
To compare single-task and dual-task tandem gait test performance between athletes after concussion with controls on observer-timed, spatio-temporal, and center-of-mass (COM) balance control measurements. Ten participants (19.0±5.5years) were prospectively identified and completed a tandem gait test protocol within 72h of concussion and again 1 week, 2 weeks, 1 month, and 2 months post-injury. Seven uninjured controls (20.0±4.5years) completed the same protocol in similar time increments. Tandem gait test trials were performed with (dual-task) and without (single-task) concurrently performing a cognitive test as whole-body motion analysis was performed. Outcome variables included test completion time, average tandem gait velocity, cadence, and whole-body COM frontal plane displacement. Concussion participants took significantly longer to complete the dual-task tandem gait test than controls throughout the first 2 weeks post-injury (mean time=16.4 [95% CI: 13.4-19.4] vs. 10.1 [95% CI: 6.4-13.7] seconds; p=0.03). Single-task tandem gait times were significantly lower 72h post-injury (p=0.04). Dual-task cadence was significantly lower for concussion participants than controls (89.5 [95% CI: 68.6-110.4] vs. 127.0 [95% CI: 97.4-156.6] steps/minute; p=0.04). Moderately-high to high correlations between tandem gait test time and whole-body COM medial-lateral displacement were detected at each time point during dual-task gait (r s =0.70-0.93; p=0.03-0.001). Adding a cognitive task during the tandem gait test resulted in longer detectable deficits post-concussion compared to the traditional single-task tandem gait test. As a clinical tool to assess dynamic motor function, tandem gait may assist with return to sport decisions after concussion. Copyright © 2017 Sports Medicine Australia. Published by Elsevier Ltd.

Improving older adults' memory performance using prior task success.
Geraci, Lisa; Miller, Tyler M
2013-06-01
Holding negative aging stereotypes can lead older adults to perform poorly on memory tests. We attempted to improve older adults' memory performance by giving them task experience that would counter their negative performance expectations. Before participating in a memory experiment, younger and older adults were given a cognitive task that they could either successfully complete, not successfully complete, or they were given no prior task. For older adults, recall was significantly higher and self-reported anxiety was significantly lower for the prior task success group relative to the other groups. There was no effect of prior task experience on younger adults' memory performance. Results suggest that older adults' memory can be improved with a single successful prior task experience.

Communication deficits may play a critical role in maintaining employment after traumatic brain injury (TBI), but links between specific communication deficits and employment outcomes have not been determined. This study identified communication measures that distinguished stably employed versus unstably employed adults with TBI. Participants were 31 adults with moderate-severe TBI who were employed full-time for at least 12 consecutive months before injury in skilled jobs and had attempted return to skilled jobs after injury. Sixteen had achieved stable employment (SE) post-injury, defined as full-time employment for ≥12 consecutive months; and 15 had unstable employment (UE). Participants completed a battery of communication tests identified in a prior qualitative study of communication skills required for skilled work. Measures of spoken language comprehension, verbal reasoning, social inference, reading and politeness in spoken discourse significantly discriminated between SE and UE groups. Two nested models were completed and compared. The first model excluded discourse data because of missing data for two UE and one SE participant. This model revealed that measures of verbal reasoning speed (β = -0.18, p = 0.05) and social inference (β = 0.19, p = 0.05) were predictive independent of the overall model. The second model included discourse politeness data and was a better overall predictor of group membership (Likelihood ratio test, Model 1: 3.824, Model 2: 2.865). Communication measures were positively associated with SE in skilled jobs after TBI. Clinicians should include assessment of communication for adults attempting return to work after TBI, paying specific attention to social inference and speed of verbal reasoning skills. Traumatic brain injury (TBI) often results in communication impairments associated with the cognitive skills underlying interpersonal skills. Communication impairment after TBI has been anecdotally associated with job instability. This research associate communication functioning with work stability after TBI in skilled jobs. These findings indicate that communication impairment should be assessed in persons with TBI returning to skilled employment after injury.

Aim This study aims to discuss current perceptions of rehabilitation and how present rehabilitation practice is affected by dominating discourses in Danish society by exploring discourses expressed in official publications and the constructed journal notes of occupational and physiotherapists' practice of stroke rehabilitation. Method The frame of reference is Fairclough's critical discourse analysis. The analysis comprises seven official documents relevant to stroke rehabilitation provided in Danish health services in 2012-2013. Also, notes written by occupational therapists and physiotherapists in medical records of 10 patients with a stroke diagnosis admitted to hospital in 2012. The documents included were read thoroughly. The texts were analyzed deductively, focusing on discursive practice on articulated understandings of rehabilitation, health practice approaches, and social practice. Results The dominating discourses seem to be Western neoliberalism organizational, medical and ethical discourses. The macro level of discourses consisted of political documents addressing rehabilitation nationally. The meso level mainly concerned medical discourses within stroke rehabilitation whereas the micro level represented local medical and ethical discourses. Conclusion The neoliberal discourse supports the medical discourse with strong emphasis on evidence-based interventions. In contrast to ethical discourses, documentation of rehabilitation practice marked more attention being paid to facilitating the patient's independence than to enabling the regaining of meaningful activities and participation. Implications for Rehabilitation Individualized rehabilitation must be organized with flexibility as it is a complex process Critical reflectiveness among health professionals is needed to provide individualized rehabilitation of high quality A broader range of stake holders, including patient organizations, are in demand within health policy making The discourses that construct rehabilitation policy and practices are sometimes in conflict, which may impact on, and impede, the rehabilitation for the individual patient.
Commentary: Forks in the road: disruption and transformation in professional development.
Kumagai, Arno K
2010-12-01
The dynamic influences underlying the development of the professional identity of physicians are not completely understood; however, one can easily imagine that the transition from the supervised work of the resident to the relative autonomy and increased authority of the attending physician is a watershed moment in this developmental process. In this issue of Academic Medicine, Westerman and colleagues present a qualitative, interview-based study exploring the experiences of newly appointed attending physicians during this transition, and from the participants' responses, they construct a conceptual model in which the new attending physicians' attempts to understand and cope with novel disruptive elements (i.e., new and unfamiliar tasks, roles, and settings) eventually give rise to a sense of mastery and personal and professional development. Although the authors use the literature of transition psychology and organizational social theory to support their model, valuable lessons may be learned from looking at the processes from an educational perspective as well. The disruptions which the authors describe find resonance in Piaget's state of "cognitive disequilibrium" or Dewey's "forked road situation," both of which link the experience of challenging or ambiguous situations with the act of reflection. Disruptive influences may stimulate explorations of self, others, and the world during this critical transition, and educational efforts in mentorship and in the creation of thoughtful discourse about these critical explorations may ultimately contribute to the development of a reflective professional self.

Retaining blood donors is a cost-effective way of ensuring a safe blood supply, yet despite the plethora of research, only 5.1% of the eligible population in Australia donate blood and 40% of these do not make a second donation. We offer an alternative to traditional approaches by conceptualizing blood donation within social representations theory as socially derived symbolic knowledge with a specific focus on cognitive polyphasia and Guimelli's (1998) normative and functional dimensions. An online survey, completed by 703 residents from NSW Australia, comprised a blood donation word association task, Likert-style questions constructed from previous word association data and contextualized blood donation statements. Individual difference scaling analysis revealed all donor groups (including non-donors) associated blood donation with a few central, albeit contradictory ideas/beliefs. Exploratory factor analysis and confirmatory factor analysis performed on a split data set of the Likert-style items reiterated this finding. Interpreted through Guimelli's dichotomy, all donor groups were aware of these contradictory normative and functional ideas/beliefs but when explicitly asked, it was the functional aspect that differentiated the groups. We argue the key to retaining donors is understanding the interdependence between how blood donation is socially understood at the societal level of discourse and donor behaviour. Translational strategies for recruitment and retention are discussed. © 2017 The British Psychological Society.
Processing and memory of information presented in narrative or expository texts.
Wolfe, Michael B W; Woodwyk, Joshua M
2010-09-01
Previous research suggests that narrative and expository texts differ in the extent to which they prompt students to integrate to-be-learned content with relevant prior knowledge during comprehension. We expand on previous research by examining on-line processing and representation in memory of to-be-learned content that is embedded in narrative or expository texts. We are particularly interested in how differences in the use of relevant prior knowledge leads to differences in terms of levels of discourse representation (textbase vs. situation model). A total of 61 university undergraduates in Expt 1, and 160 in Expt 2. In Expt 1, subjects thought out loud while comprehending circulatory system content embedded in a narrative or expository text, followed by free recall of text content. In Expt 2, subjects read silently and completed a sentence recognition task to assess memory. In Expt 1, subjects made more associations to prior knowledge while reading the expository text, and recalled more content. Content recall was also correlated with amount of relevant prior knowledge for subjects who read the expository text but not the narrative text. In Expt 2, subjects reading the expository text (compared to the narrative text) had a weaker textbase representation of the to-be-learned content, but a marginally stronger situation model. Results suggest that in terms of to-be-learned content, expository texts trigger students to utilize relevant prior knowledge more than narrative texts.
Probing quantum state space: does one have to learn everything to learn something?
Carmeli, Claudio; Heinosaari, Teiko; Schultz, Jussi; Toigo, Alessandro

Determining the state of a quantum system is a consuming procedure. For this reason, whenever one is interested only in some particular property of a state, it would be desirable to design a measurement set-up that reveals this property with as little effort as possible. Here, we investigate whether, in order to successfully complete a given task of this kind, one needs an informationally complete measurement, or if something less demanding would suffice. The first alternative means that in order to complete the task, one needs a measurement which fully determines the state. We formulate the task as a membership problem related to a partitioning of the quantum state space and, in doing so, connect it to the geometry of the state space. For a general membership problem, we prove various sufficient criteria that force informational completeness, and we explicitly treat several physically relevant examples. For the specific cases that do not require informational completeness, we also determine bounds on the minimal number of measurement outcomes needed to ensure success in the task.

Virtual Reality (VR) Head-Mounted Displays (HMDs) are on the verge of becoming commodity hardware available to the average user and feasible to use as a tool for 3D work. Some HMDs include front-facing cameras, enabling Augmented Reality (AR) functionality. Apart from avoiding collisions with the environment, interaction with virtual objects may also be affected by seeing the real environment. However, whether these effects are positive or negative has not yet been studied extensively. For most tasks it is unknown whether AR has any advantage over VR. In this work we present the results of a user study in which we compared user performance measured in task completion time on a 9 degrees of freedom object selection and transformation task performed either in AR or VR, both with a 3D input device and a mouse. Our results show faster task completion time in AR over VR. When using a 3D input device, a purely VR environment increased task completion time by 22.5 percent on average compared to AR ( ). Surprisingly, a similar effect occurred when using a mouse: users were about 17.3 percent slower in VR than in AR ( ). Mouse and 3D input device produced similar task completion times in each condition (AR or VR) respectively. We further found no differences in reported comfort.

Impact of induced joy on literacy in children: does the nature of the task make a difference?
Tornare, Elise; Cuisinier, Frédérique; Czajkowski, Nikolai O; Pons, Francisco
2017-04-01
This research examined whether induced joy influences fifth graders' performance in literacy tasks. Children were asked to recall a joyful experience, used as a joy induction, before completing either a grammar (Study 1) or textual comprehension task (Study 2). The grammar task involved understanding at the surface level and retrieval of appropriate declarative and procedural knowledge, but limited elaboration unlike the textual comprehension task, which tackled inference generation. By differentiating tasks based on depth of processing required for completion we aimed at testing the validity of two concurrent hypotheses: that of a facilitating effect and that of a detrimental effect of induced joy. Compared to controls, joy induced children showed better performance on the grammar task - specifically children with lower language ability. No differences across groups emerged as a function of joy induction on the text comprehension task. Results are discussed with respect to emotion effects on cognition.
Homework setting in cognitive behavioral therapy: A study of discursive strategies.
Beckwith, Andrew; Crichton, Jonathan
2014-01-01
In recent years cognitive behavioral therapy (CBT), a form ofpsychotherapy, has risen to prominence due to a large number of studies attesting to its efficacy. A crucial part of the model of CBT is the use of the therapeutic strategy, homework, in which the client undertakes therapeutic tasks between sessions. The focus of this study is on how homework is implemented in sessions of CBT. This is undertaken through an analysis utilizing theme-orientated discourse analysis of video recorded sessions of CBT of one therapist and a client. Through tracking the focal theme of homework, the analysis focuses on homework as a face-threatening act (Brown and Levinson 1987) and how discursive strategies are employed to manage this issue. Other analytic themes include the use of frames (Goffman 1974) and constructed dialogue (Tannen 2007). It is the expertise of the therapist in putting into practice the therapeutic task of homework that is the subject of this study.

Our study explores inhibitory control across a range of widely recognised memory and behavioural tasks. Eighty-seven never-depressed participants completed a series of tasks designed to measure inhibitory control in memory and behaviour. Specifically, a variant of the selective retrieval-practice and the Think/No-Think tasks were employed as measures of memory inhibition. The Stroop-Colour Naming and the Go/No-Go tasks were used as measures of behavioural inhibition. Participants completed all 4 tasks. Task presentation order was counterbalanced across 3 separate testing sessions for each participant. Standard inhibitory forgetting effects emerged on both memory tasks but the extent of forgetting across these tasks was not correlated. Furthermore, there was no relationship between memory inhibition tasks and either of the main behavioural inhibition measures. At a time when cognitive inhibition continues to gain acceptance as an explanatory mechanism, our study raises fundamental questions about what we actually know about inhibition and how it is affected by the processing demands of particular inhibitory tasks.

This study investigated the relationship of locus-of-control orientations and task structure to the science problem-solving performance of 100 same-sex, sixth-grade student pairs. Pairs performed a four-variable problem-solving task, racing cylinders down a ramp in a series of trials to determine the 3 fastest of 18 different cylinders. The task was completed in one of two treatment conditions: the structured condition with moderate cuing and the unstructured condition with minimal cuing. Pairs completed an after-task assessment, predicting the results of proposed cylinder races, to measure the ability to understand and apply task concepts. Overall conclusions were: (1) There was no relationship between locus-of-control orientation and effectiveness of problem-solving strategy; (2) internality was significantly related to higher accuracy on task solutions and on after-task predictions; (3) there was no significant relationship between task structure and effectiveness of problem-solving strategy; (4) solutions to the task were more accurate in the unstructured task condition; (5) internality related to more accurate solutions in the unstructured task condition.

Unfinished care has a strong relationship with quality of nursing care. Most issues related to tasks incompletion arise from staffing and workload. This study was conducted to assess the workload of nurses, the nursing activities (tasks) nurses commonly performed on medical and surgical wards, elements of nursing care activities left incomplete by nurses during a shift, factors contributing to task incompletion and the relationship between staffing, demographic variables and task incompletion. Exploratory survey using a self-administered questionnaire developed from IHOC survey, USA. All full time registered nurses working on the general medical and surgical wards of five government general hospitals in Kuwait. Research assistants distributed and collected back the questionnaires. Four working days were given to participants to complete and return the questionnaires. A total of 820 questionnaires were distributed and 95% were returned. Descriptive and inferential analysis using SPSS-11. The five most frequently performed nursing activities were: administration of medications, assessing patient condition, preparing/updating nursing care plans, close patient monitoring and client health teaching. The most common nursing activities nurses were unable to complete were: comfort talk with patient and family, adequate documentation of nursing care, oral hygiene, routine catheter care and starting or changing IV fluid on time. Tasks were more complete when the nurse-patient load was less than 5. Nurses' age and educational background influenced task completion while nurses' gender had no influence on it. Increased patient loads, resulting in increased frequency of nursing tasks and non-nursing tasks, were positively correlated to incompletion of nursing activities during the shift. Emphasis should be given to maintaining the optimum nurse-patient load and decreasing the non-nursing workload of nurses to enhance the quality of nursing care.

Despite growing interest in developing ecological assessment of difficulties in patients with Alzheimer's disease new methods assessing the cognitive difficulties related to functional activities are missing. To complete current evaluation, the use of Serious Games can be a promising approach as it offers the possibility to recreate a virtual environment with daily living activities and a precise and complete cognitive evaluation. The aim of the present study was to evaluate the usability and the screening potential of a new ecological tool for assessment of cognitive functions in patients with Alzheimer's disease. Eighteen patients with Alzheimer's disease and twenty healthy controls participated to the study. They were asked to complete six daily living virtual tasks assessing several cognitive functions: three navigation tasks, one shopping task, one cooking task and one table preparation task following a one-day scenario. Usability of the game was evaluated through a questionnaire and through the analysis of the computer interactions for the two groups. Furthermore, the performances in terms of time to achieve the task and percentage of completion on the several tasks were recorded. Results indicate that both groups subjectively found the game user friendly and they were objectively able to play the game without computer interactions difficulties. Comparison of the performances between the two groups indicated a significant difference in terms of percentage of achievement of the several tasks and in terms of time they needed to achieve the several tasks. This study suggests that this new Serious Game based assessment tool is a user-friendly and ecological method to evaluate the cognitive abilities related to the difficulties patients can encounter in daily living activities and can be used as a screening tool as it allowed to distinguish Alzheimer's patient's performance from healthy controls.

Single-limb stance is maintained via the integration of visual, vestibular and somatosensory afferents. Musculoskeletal injury challenges the somatosensory system to reweight distorted sensory afferents. This investigation supplements kinetic analysis of eyes-open and eyes-closed single-limb stance tasks with a kinematic profile of lower limb postural orientation in an acute lateral ankle sprain group to assess the adaptive capacity of the sensorimotor system to injury. Sixty-six participants with first-time acute lateral ankle sprain completed a 20-second eyes-open single-limb stance task on their injured and non-injured limbs (task 1). Twenty-three of these participants successfully completed the same 20-second single-limb stance task with their eyes closed (task 2). A non-injured control group of 19 participants completed task 1, with 16 completing task 2. 3-dimensional kinematics of the hip, knee and ankle joints, as well as associated fractal dimension of the center-of-pressure path were determined for each limb during these tasks. Between trial analyses revealed significant differences in stance limb kinematics and fractal dimension of the center-of-pressure path for task 2 only. The control group bilaterally assumed a position of greater hip flexion compared to injured participants on their side-matched "involved"(7.41 [6.1°] vs 1.44 [4.8]°; η(2)=.34) and "uninvolved" (9.59 [8.5°] vs 2.16 [5.6°]; η(2)=.31) limbs, with a greater fractal dimension of the center-of-pressure path (involved limb=1.39 [0.16°] vs 1.25 [0.14°]; uninvolved limb=1.37 [0.21°] vs 1.23 [0.14°]). Bilateral impairment in postural control strategies present following a first time acute lateral ankle sprain. Copyright © 2014 Elsevier Ltd. All rights reserved.
Selecting Tasks for Evaluating Human Performance as a Function of Gravity

A challenge in understanding human performance as a function of gravity is determining which tasks to research. Initial studies began with treadmill walking, which was easy to quantify and control. However, with the development of pressurized rovers, it is less important to optimize human performance for ambulation as rovers will likely perform gross translation for them. Future crews are likely to spend much of their extravehicular activity (EVA) performing geology, construction and maintenance type tasks, for which it is difficult to measure steady-state-workloads. To evaluate human performance in reduced gravity, we have collected metabolic, biomechanical and subjective data for different tasks at varied gravity levels. Methods: Ten subjects completed 5 different tasks including weight transfer, shoveling, treadmill walking, treadmill running and treadmill incline walking. All tasks were performed shirt-sleeved at 1-g, 3/8-g and 1/6-g. Off-loaded conditions were achieved via the Active Response Gravity Offload System. Treadmill tasks were performed for 3 minutes with reported oxygen consumption (VO2) averaged over the last 2 minutes. Shoveling was performed for 3 minutes with metabolic cost reported as ml O2 consumed per kg material shoveled. Weight transfer reports metabolic cost as liters O2 consumed to complete the task. Statistical analysis was performed via repeated measures ANOVA. Results: Statistically significant metabolic differences were noted between all 3 gravity levels for treadmill running and incline walking. For the other 3 tasks, there were significant differences between 1-g and each reduced gravity, but not between 1/6-g and 3/8-g. For weight transfer, significant differences were seen between gravities in both trial-average VO2 and time-to-completion with noted differences in strategy for task completion. Conclusion: To determine if gravity has a metabolic effect on human performance, this research may indicate that tasks should be selected that require the subject to work vertically against the force of gravity.

Fuzzy System has demonstrated their ability to solve different kinds of problem in various application domains. There is an increasing interest to apply fuzzy concept to improve tasks of any system. Here case study of a thermal power plant is considered. Existing time estimation represents time to complete tasks. Applying fuzzy linear approach it becomes clear that after each confidence level least time is taken to complete tasks. As time schedule is less than less amount of cost is needed. Objective of this paper is to show how one system becomes more efficient in applying Fuzzy Linear approach. In this paper we want to optimize the time estimation to perform all tasks in appropriate time schedules. For the case study, optimistic time (to), pessimistic time (tp), most likely time(tm) is considered as data collected from thermal power plant. These time estimates help to calculate expected time(te) which represents time to complete particular task to considering all happenings. Using project evaluation and review technique (PERT) and critical path method (CPM) concept critical path duration (CPD) of this project is calculated. This tells that the probability of fifty percent of the total tasks can be completed in fifty days. Using critical path duration and standard deviation of the critical path, total completion of project can be completed easily after applying normal distribution. Using trapezoidal rule from four time estimates (to, tm, tp, te), we can calculate defuzzyfied value of time estimates. For range of fuzzy, we consider four confidence interval level say 0.4, 0.6, 0.8,1. From our study, it is seen that time estimates at confidence level between 0.4 and 0.8 gives the better result compared to other confidence levels.

Objective. One strategy to improve the effectiveness of prosthetic vision devices is to process incoming images to ensure that key information can be perceived by the user. This paper presents the first comprehensive results of vision function testing for a suprachoroidal retinal prosthetic device utilizing of 20 stimulating electrodes. Further, we investigate whether using image filtering can improve results on a light localization task for implanted participants compared to minimal vision processing. No controlled implanted participant studies have yet investigated whether vision processing methods that are not task-specific can lead to improved results. Approach. Three participants with profound vision loss from retinitis pigmentosa were implanted with a suprachoroidal retinal prosthesis. All three completed multiple trials of a light localization test, and one participant completed multiple trials of acuity tests. The visual representations used were: Lanczos2 (a high quality Nyquist bandlimited downsampling filter); minimal vision processing (MVP); wide view regional averaging filtering (WV); scrambled; and, system off. Main results. Using Lanczos2, all three participants successfully completed a light localization task and obtained a significantly higher percentage of correct responses than using MVP (p≤slant 0.025) or with system off (p\\lt 0.0001). Further, in a preliminary result using Lanczos2, one participant successfully completed grating acuity and Landolt C tasks, and showed significantly better performance (p=0.004) compared to WV, scrambled and system off on the grating acuity task. Significance. Participants successfully completed vision tasks using a 20 electrode suprachoroidal retinal prosthesis. Vision processing with a Nyquist bandlimited image filter has shown an advantage for a light localization task. This result suggests that this and targeted, more advanced vision processing schemes may become important components of retinal prostheses to enhance performance.

Patient education materials have the potential to strengthen the health literacy of patients. Previous studies indicate that readability and suitability may be improved. The aim of this study was to explore and analyze discourses inherent in patient education materials since analysis of discourses could illuminate values and norms inherent in them. Clinics in Sweden that provided colorectal cancer surgery allowed access to written information and 'welcome letters' sent to patients. The material was analysed by means of discourse analysis, embedded in Derrida's approach of deconstruction. The analysis revealed a biomedical discourse and a hospitality discourse. In the biomedical discourse, the subject position of the personnel was interpreted as the messenger of medical information while that of the patients as the carrier of diagnoses and recipients of biomedical information. In the hospitality discourse, the subject position of the personnel was interpreted as hosts who invite and welcome the patients as guests. The study highlights the need to eliminate paternalism and fosters a critical reflective stance among professionals regarding power and paternalism inherent in health care communication. © 2015 John Wiley & Sons Ltd.
Task rotation in an underground coal mine: A pilot study.
Jones, Olivia F; James, Carole L
2018-01-01
Task rotation is used to decrease the risk of workplace injuries and improve work satisfaction. To investigate the feasibility, benefits and challenges of implementing a task rotation schedule within an underground coalmine in NSW, Australia. A mixed method case control pilot study with the development and implementation of a task rotation schedule for 6 months with two work crews. A questionnaire including The Nordic Musculoskeletal Questionnaire, The Need for Recovery after Work Scale, and The Australian WHOQOL- BREF Australian Edition was used to survey workers at baseline, 3 and 6 months. A focus group was completed with the intervention crew and management at the completion of the study. In total, twenty-seven participants completed the survey. Significant improvements in the psychological and environmental domains of the WHOQOL-BREF questionnaire were found in the intervention crew. Musculoskeletal pain was highest in the elbow, lower back and knee, and fatigue scores improved, across both groups. The intervention crew felt 'mentally fresher', 'didn't do the same task twice in a row', and 'had more task variety which made the shift go quickly'. Task rotation was positively regarded, with psychological benefits identified. Three rotations during a 9-hour shift were feasible and practical in this environment.

Both empirical and anecdotal evidence supports the idea that choice is preferred by humans. Previous research has demonstrated that this preference extends to nonhuman animals, but it remains largely unknown whether animals will actively seek out or prefer opportunities to choose. Here we explored the issue of whether capuchin and rhesus monkeys choose to choose. We used a modified version of the SELECT task-a computer program in which monkeys can choose the order of completion of various psychomotor and cognitive tasks. In the present experiments, each trial began with a choice between two icons, one of which allowed the monkey to select the order of task completion, and the other of which led to the assignment of a task order by the computer. In either case, subjects still had to complete the same number of tasks and the same number of task trials. The tasks were relatively easy, and the monkeys responded correctly on most trials. Thus, global reinforcement rates were approximately equated across conditions. The only difference was whether the monkey chose the task order or it was assigned, thus isolating the act of choosing. Given sufficient experience with the task icons, all monkeys showed a significant preference for choice when the alternative was a randomly assigned order of tasks. To a lesser extent, some of the monkeys maintained a preference for choice over a preferred, but computer-assigned, task order that was yoked to their own previous choice selection. The results indicated that monkeys prefer to choose when all other aspects of the task are equated.
Untying the Gordian knot of creation: metaphors for the Human Genome Project in Greek newspapers.
Gogorosi, Eleni
2005-12-01
This article studies the metaphorical expressions used by newspapers to present the near completion of the Human Genome Project (HGP) to the Greek public in the year 2000. The analysis, based on cognitive metaphor theory, deals with the most frequent or captivating metaphors used to refer to the human genome, which give rise to both conventional and novel expressions. The majority of creative metaphorical expressions participate in the discourse of hope and promise propagated by the Greek media in an attempt to present the HGP and its outcome in a favorable light. Instances of the competing discourse of fear and danger are much rarer but can also be found in creative metaphorical expressions. Metaphors pertaining to the Greek culture or to ancient Greek mythology tend to carry a special rhetorical force. However, it will be shown that the Greek press strategically used most of the metaphors that circulated globally at the time, not only culture specific ones.

Qualitative analysis of videotapes of three algebra teachers' instruction focused on different categories thought to influence teaching representations with technology: representations, discourse, technology, and decisions. Models for rating teachers low, medium, or high for each of these categories were created using a priori codes and grounded methodology. A cross case analysis was conducted after the completion of the case studies by comparing and contrasting the three cases. Data revealed that teachers' decisions shifted to incorporate the difference in student ideas/representations made visible by the CCT into their instruction and ultimately altered their orientation to mathematics teaching. The shift in orientation seemed to lead to the teachers' growth with regards to representations, discourse, and technology.
Politics of change: the discourses that inform organizational change and their capacity to silence.
McMillan, Kim
2016-09-01
Changes in healthcare organizations are inevitable and occurring at unprecedented rates. Such changes greatly impact nurses and their work, yet these experiences are rarely explored. Organizational change discourses remain grounded in perspectives that explore and explain systems, often not the people within them. Change processes in healthcare organizations informed by such organizational discourses validate only certain perspectives and forms of knowledge. This fosters exclusionary practices, limiting the capacity of certain individuals or groups of individuals to effectively contribute to change discourses and processes. The reliance on mainstream organizational discourses in healthcare organizations has left little room for the exploration of diverse perspectives on the subject of organizational change, particularly those of nurses. Michel Foucault's work challenges dominant discourse and suggest that strong reliance's on specific discourses effectively disqualify certain forms of knowledge. Foucault's writings on disqualified knowledge and parrhesia (truth telling and frank speech) facilitate the critical exploration of discourses that inform change in healthcare organizations and nurses capacities to contribute to organizational discourses. This paper explores the capacity of nurses to speak their truths within rapidly and continuously changing healthcare organizations when such changes are often driven by discourses not derived from nursing knowledge or experience. © 2016 John Wiley & Sons Ltd.

Prior research has suggested that emotion and working memory domains are integrated, such that positive affect enhances verbal working memory, whereas negative affect enhances spatial working memory (Gray, 2004; Storbeck, 2012). Simon (1967) postulated that one feature of emotion and cognition integration would be reciprocal connectedness (i.e., emotion influences cognition and cognition influences emotion). We explored whether affective judgments and attention to affective qualities are biased by the activation of verbal and spatial working memory mind-sets. For all experiments, participants completed a 2-back verbal or spatial working memory task followed by an endorsement task (Experiments 1 & 2), word-pair selection task (Exp. 3), or attentional dot-probe task (Exp. 4). Participants who had an activated verbal, compared with spatial, working memory mind-set were more likely to endorse pictures (Exp. 1) and words (Exp. 2) as being more positive and to select the more positive word pair out of a set of word pairs that went 'together best' (Exp. 3). Additionally, people who completed the verbal working memory task took longer to disengage from positive stimuli, whereas those who completed the spatial working memory task took longer to disengage from negative stimuli (Exp. 4). Interestingly, across the 4 experiments, we observed higher levels of self-reported negative affect for people who completed the spatial working memory task, which was consistent with their endorsement and attentional bias toward negative stimuli. Therefore, emotion and working memory may have a reciprocal connectedness allowing for bidirectional influence.

With the increase of tablet usage in both office and industrial workplaces, it is critical to investigate the influence of tablet usage on spine posture and movement. To quantify spine kinematics while participants interacted with a tablet or desktop computer. Fourteen participants volunteered for this study. Marker clusters were fixed onto body regions to analyze cervical and lumbar spine posture and sampled at 32 Hz (Optotrak Certus, NDI, Waterloo, Canada). Participants sat for one hour in total. Cervical and lumbar median angles and range of motion (10th to 90th % ile angles) were extracted from amplitude probability distribution functions performed on the angle data. Using a sloped desk surface at 15°, compared to a flat desk, influenced cervical flexion (p = 0.0228). Completing the form fill task resulted in the highest degree of cervical flexion (p = 0.0008) compared to the other tasks completed with cervical angles between 6.1°-8.5° higher than emailing and reading respectively. An interaction between device and task (p = 0.0061) was found for relative lumbar median spine angles. Increased lumbar flexion was recorded when using a computer versus a tablet to complete various tasks. Task influenced both cervical and lumbar spine posture with the highest cervical flexion occurring while completing a simulated data entry task. A work surface slope of 15° decreased cervical spine flexion compared to a horizontal work surface slope.

The purpose of this analysis was to compare observer-rated tasks in patients implanted with the Argus II Retinal Prosthesis System, when the device is ON versus OFF. The Functional Low-Vision Observer Rated Assessment (FLORA) instrument was administered to 26 blind patients implanted with the Argus II Retinal Prosthesis System at a mean follow-up of 36 months. FLORA is a multi-component instrument that consists in part of observer-rated assessment of 35 tasks completed with the device ON versus OFF. The ease with which a patient completes a task is scored using a four-point scale, ranging from easy (score of 1) to impossible (score of 4). The tasks are evaluated individually and organised into four discrete domains, including 'Visual orientation', 'Visual mobility', 'Daily life and 'Interaction with others'. Twenty-six patients completed each of the 35 tasks. Overall, 24 out of 35 tasks (69 per cent) were statistically significantly easier to achieve with the device ON versus OFF. In each of the four domains, patients' performances were significantly better (p < 0.05) with the device ON versus OFF, ranging from 19 to 38 per cent improvement. Patients with an Argus II Retinal Prosthesis implanted for 18 to 44 months (mean 36 months), demonstrated significantly improved completion of vision-related tasks with the device ON versus OFF. © 2016 The Authors Clinical and Experimental Optometry published by John Wiley & Sons Australia, Ltd on behalf of Optometry Australia.

The present study investigated whether developmental changes in cognitive control may underlie improvements of time-based prospective memory. Five-, 7-, 9-, and 11-year-olds (N = 166) completed a driving simulation task (ongoing task) in which they had to refuel their vehicle at specific points in time (PM task). The availability of cognitive control resources was experimentally manipulated by imposing a secondary task that required divided attention. Children completed the driving simulation task both in a full-attention condition and a divided-attention condition where they had to carry out a secondary task. Results revealed that older children performed better than younger children on the ongoing task and PM task. Children performed worse on the ongoing and PM tasks in the divided-attention condition compared to the full-attention condition. With respect to time monitoring in the final interval prior to the PM target, divided attention interacted with age such that older children's time monitoring was more negatively affected by the secondary task compared to younger children. Results are discussed in terms of developmental shifts from reactive to proactive monitoring strategies.

As a discipline, neuroethics addresses a range of questions and issues generated by basic neuroscientific research (inclusive of studies of putative neurobiological processes involved in moral and ethical cognition and behavior), and its use and meanings in the clinical and social spheres. Here, we present Part 4 of a four-part bibliography of the neuroethics literature focusing on clinical and social applications of neuroscience, to include: the treatment-enhancement discourse; issues arising in neurology, psychiatry, and pain care; neuroethics education and training; neuroethics and the law; neuroethics and policy and political issues; international neuroethics; and discourses addressing "trans-" and "post-" humanity. To complete a systematic survey of the literature, 19 databases and 4 individual open-access journals were employed. Searches were conducted using the indexing language of the U.S. National Library of Medicine (NLM). A Python code was used to eliminate duplications in the final bibliography. When taken with Parts 1-3, this bibliography aims to provide a listing of international peerreviewed papers, books, and book chapters published from 2002 through 2016. While seeking to be as comprehensive as possible, it may be that some works were inadvertently and unintentionally not included. We therefore invite commentary from the field to afford completeness and contribute to this bibliography as a participatory work-in-progress.

Bedtime worry, including worrying about incomplete future tasks, is a significant contributor to difficulty falling asleep. Previous research showed that writing about one's worries can help individuals fall asleep. We investigated whether the temporal focus of bedtime writing-writing a to-do list versus journaling about completed activities-affected sleep onset latency. Fifty-seven healthy young adults (18-30) completed a writing assignment for 5 min prior to overnight polysomnography recording in a controlled sleep laboratory. They were randomly assigned to write about tasks that they needed to remember to complete the next few days (to-do list) or about tasks they had completed the previous few days (completed list). Participants in the to-do list condition fell asleep significantly faster than those in the completed-list condition. The more specifically participants wrote their to-do list, the faster they subsequently fell asleep, whereas the opposite trend was observed when participants wrote about completed activities. Therefore, to facilitate falling asleep, individuals may derive benefit from writing a very specific to-do list for 5 min at bedtime rather than journaling about completed activities.

The purpose of this study was to determine the sensitivity of discourse gist measures to the early cognitive-linguistic changes in Alzheimer disease (AD) and in the preclinical stages. Differences in discourse abilities were examined in 25 cognitively normal adults, 24 adults with mild probable AD, and 20 adults with mild cognitive impairment (MCI) at gist and detail levels of discourse processing. The authors found that gist and detail levels of discourse processing were significantly impaired in persons with AD and MCI as compared with normal control subjects. Gist-level discourse processing abilities showed minimal overlap between cognitively normal control subjects and those with mild AD. Moreover, the majority of the persons with MCI performed in the range of AD on gist measures. These findings indicate that discourse gist measures hold promise as a diagnostic complement to enhance early detection of AD. Further studies are needed to determine how early the discourse gist deficits arise in AD.
Discourse analysis and the impact of the philosophy of Enlightenment in nursing research.
Beedholm, Kirsten; Lomborg, Kirsten; Frederiksen, Kirsten
2014-06-01
Discourse analysis has been introduced into nursing research as an approach which has the potential to offer new perspectives and to pose new questions to taken-for-granted assumptions. However, critique has arisen that when applied to nursing studies, the epistemological foundation of the discourse analysis is often overlooked. It is furthermore claimed that the methodological inspiration does not lead to any new insights and that these studies can hardly be differentiated from more traditional studies. This study supports this critique, arguing that the challenges of implementing discourse analysis in nursing research reflect a dominant pattern of thought in the discourse of the nursing profession that have held sway throughout the last century. We argue that this pattern of thought stems from the Western philosophy of consciousness and the conception of the sovereign subject. By applying a discourse analytical perspective to the discourse of the nursing profession itself, this study elucidates the challenges of applying discourse analysis in nursing research. © 2013 John Wiley & Sons Ltd.

Activities designed to be performed outside of the intervention are considered an essential aspect of the effectiveness of cognitive-behavioral therapy. However, these have received little attention in interventions aimed at individuals with subclinical depressive symptoms who do not yet meet diagnostic criteria for depression (indicated prevention). In this study, the completion of tasks given as homework and their relationship with post-treatment depressive symptoms was with relation to an indicated prevention of depression intervention. Eighty-nine female non-professional caregivers recruited from an official registry completed an intervention involving 11 homework tasks. Tasks performed were recorded and depressive symptoms were assessed with the Center for Epidemiologic Studies Depression Scale (CES-D). Among caregivers, 80.9% completed 9-11 tasks. The number of tasks performed was associated with post-treatment depressive symptoms, with 9 being optimal for clinically significant improvement. These findings highlight the relationship between homework and post-treatment depressive symptoms.

Previous studies have shown that completed prospective memory (PM) intentions entail aftereffects in terms of ongoing-task-performance decrements in trials containing repeated PM cues which previously served as PM cues triggering the intended action. Previous research reported that PM aftereffects decrease over time, thus revealing a specific time course of PM aftereffects. In the present study, we tested two accounts for this pattern, assuming either that the decline of aftereffects is related to the temporal distance to PM task completion or may be a result of the repeated exposure of repeated PM cues in the ongoing task. In three experiments, we manipulated both the temporal distance to PM task completion and the frequency of repeated PM cues and demonstrated that aftereffects of completed intentions declined with repeated exposure of formerly relevant PM cues. In addition, effects of repeated exposure were not only limited to the repetition of specific PM-cue exemplars but also generalized to other semantically related PM cues within the PM-cue category. Together, findings show that decreased aftereffects of completed intentions are not related to the temporal duration of the subsequent test block, but crucially depend on the repeated exposure of the previously relevant PM cues.

This study explored whether shared self-control across a family system, including adolescent, mother, and father self-control, as well as the interaction of mother and father self-control, was associated with ease of completing adherence tasks and the completion of adherence behaviors related to the Type 1 diabetes (T1D) regimen. One hundred thirty-seven adolescents (M = 13.48 years), mothers, and fathers completed a self-report measure of self-control, while adolescents also self-reported on ease of completing adherence tasks and the frequency with which they completed adherence tasks. Higher adolescent, mother, father, and the interaction of mother and father self-control were each associated with greater adolescent perceptions of ease of completing adherence tasks. Also, greater adolescent perception of ease of adherence mediated the association of higher adolescent, father, and the interaction of mother and father self-control on more frequent adherence behaviors. The results are consistent with the idea that family members may share the load of self-control within the family system. The results point to the importance of assessing and intervening within the entire family system to support improved quality of life and better adherence to the medical regimen in adolescents with Type 1 diabetes.

To increase quantified information about the effectiveness and subjective workload of force information relayed through manipulator input control devices, a space related task was performed by eight subjects with kinesthetic force feedback and/or local force accommodation through three different input control devices (i.e., hand controllers) operating in rate control mode. Task completion time, manipulator work, and subjective responses were measured. Results indicated a difference among the hand controllers. For the Honeywell six degree-of-freedom hand controller, the overall task completion times were shortest, the amount of work exerted was the least, and was the most preferred by test subjects. Neither force accommodation with or without reflection resulted in shorter task completion times or reduced work although those conditions were better than no force information for some aspects. Comparisons of results from previous studies are discussed.
Elementary students' engagement in failure-prone engineering design tasks
NASA Astrophysics Data System (ADS)
Andrews, Chelsea Joy
Although engineering education has been practiced at the undergraduate level for over a century, only fairly recently has the field broadened to include the elementary level; the pre-college division of the American Society of Engineering Education was established in 2003. As a result, while recent education standards require engineering in elementary schools, current studies are still filling in basic research on how best to design and implement elementary engineering activities. One area in need of investigation is how students engage with physical failure in design tasks. In this dissertation, I explore how upper elementary students engage in failure-prone engineering design tasks in an out-of-school environment. In a series of three empirical case studies, I look closely at how students evaluate failed tests and decide on changes to their design constructions, how their reasoning evolves as they repeatedly encounter physical failure, and how students and facilitators co-construct testing norms where repetitive failure is manageable. I also briefly investigate how students' engagement differs in a task that features near-immediate success. By closely examining student groups' discourse and their interactions with their design constructions, I found that these students: are able to engage in iteration and see failure-as-feedback with minimal externally-imposed structure; seem to be designing in a more sophisticated manner, attending to multiple causal factors, after experiencing repetitive failure; and are able to manage the stress and frustration of repetitive failure, provided the co-constructed testing norms of the workshop environment are supportive of failure management. These results have both pedagogical implications, in terms of how to create and facilitate design tasks, and methodological implications--namely, I highlight the particular insights afforded by a case study approach for analyzing engagement in design tasks.

This article examines how discourses on mental illness are negotiated in mental health practice and their implications for the subjective experiences of psychiatric patients. Based on a Foucauldian analysis of ethnographic data from two mental health institutions in Denmark--an outpatient clinic and an inpatient ward--this article identifies three discourses in the institutions: the instability discourse, the discourse of "really ill," and the lack of insight discourse. This article indicates that patients were required to develop a finely tuned and precise sense of the discourses and ways to appear in front of professionals if they wished to have a say in their treatment. We suggest that the extent to which an individual patient was positioned as ill seemed to rely more on his or her ability to navigate the discourses and the psychiatric setting than on any objective diagnostic criteria. Thus, we argue that illness discourses in mental health practice are not just materialized as static biomedical understandings, but are complex and diverse--and have implications for patients' possibilities to understand themselves and become understandable to professionals. © The Author(s) 2015.
