In adolescence, a component of a successful identity quest consists in elaborating the aggressiveness, be it endured or acted out, in an imaginary and symbolic manner. We will present a comparative study between anxious and violent adolescents, based on the Rorschach test. As the handling of aggressiveness by means of various defense mechanisms and coping strategies contributes to the construction of a sense of reality and of coherent representations of oneself and the others, the Rorschach test is a pertinent tool to study the vicissitudes of the identity quest of medium adolescence. On the other hand, many studies demonstrate that it is also a precious tool allowing diagnosis of the risks of evolution towards character pathology and personality disorders belonging to cluster B of the DSM, or towards emotional disorders and suicidal tendencies. Thus, it can help initiating appropriate therapeutic measures in a spirit of tertiary prevention. We present a comparative study between a sample of 20 adolescents suffering from anxiety and inhibition of aggressiveness (subgroup anxiety) and a second sample of 20 adolescents suffering from exteriorized aggressiveness and violent behavior (subgroup violence). The inclusion into the subgroups was based on clinical interviews and a thorough psychological assessment, using the criteria of categorical psychopathology. The comparative study between the two subgroups is based on an original rating scale constructed in the phenomenological and structural tradition, reflecting the global judgment of the experienced clinical psychologist. It permits using the Rorschach test as a research tool by making the step from qualitative analysis towards quantification and the use of inferential and multidimensional statistics. It also allows computing correlations between the Rorschach test and psychometric scales or other projective tests, using specific rating scales of the same type. After showing the descriptive demographic data, we

Relationship of Pretreatment Rorschach Factors to Symptoms, Quality of Life, and Real-Life Functioning in a 3-Year Follow-Up of Traumatized Refugee Patients

ABSTRACT Response to mental health treatment varies highly among refugee patients. Research has not established which factors relate to differences in outcome. This study is a follow-up of Opaas and Hartmann's (2013) Rorschach Inkblot Method (RIM; Exner, 2003) pretreatment study of traumatized refugees, where 2 RIM principal components, Trauma Response and Reality Testing, were found descriptive of participants’ trauma-related personality functioning. This study's aims were to examine relationships of the RIM components with measures of anxiety, depression, posttraumatic stress, quality of life (QOL), employment, and exile language skills throughout 3 years. We found that impaired Reality Testing was related to more mental health symptoms and poorer QOL; furthermore, individuals with adequate Reality Testing improved in posttraumatic stress symptoms the first year and retained their improvement. Individuals with impaired Reality Testing deteriorated the first year and improved only slightly the next 2 years. The results of this study imply that traumatized refugee patients with impaired Reality Testing might need specific treatment approaches. Research follow-up periods should be long enough to detect changes. The reality testing impairment revealed by the RIM, mainly perceptual in quality, might not be easily detected by diagnostic interviews and self-report. PMID:26528822

The effects of violent media on adolescent inkblot responses: implications for clinical and forensic assessments.

PubMed

Hess, T H; Hess, K D; Hess, A K

1999-04-01

Two experiments were conducted to assess the degree to which violent media stimulate violent fantasy as depicted on inkblot responses. In Experiment I, 41 gifted high school students were exposed to a bucolic or violent film clip and then were asked to produce inkblot responses. In Experiment II, a second sample of 43 additional students were exposed to a verbal description of the bucolic or violent scene to assess whether the "hot" or "cooler" media (McLuhan, 1964) had different effects on the inkblot responses. In both experiments, the media exposure led to increased levels of violent responses, and in both cases males produced more violent responses. There was no sex by media interaction effect. Implications for clinical and forensic assessments are presented.

Cognitive mediational deficits and the role of coping styles in pedophile and ephebophile Roman Catholic clergy.

This study was designed to examine hypothesized differences between sex offending and nonoffending Roman Catholic clergy on cognitive mediation abilities as measured by the Rorschach Inkblot Test (H. Rorschach, 1921/1942). This study compared 78 priest pedophiles and 77 priest ephebophiles with 80 nonoffending priest controls on the Inkblot test using J. E. Exner's (2003) Comprehensive System. The three groups were compared on seven variables that constitute Exner's Cognitive Mediation cluster. Additionally, the groups' coping styles were compared to examine the interaction of coping style and cognitive mediational abilities. We found interactions between coping style and offending status across most of the cognitive variables indicating impairment in the mild to pathological ranges. Moreover, significantly higher unusual thinking styles (Xu%) and significantly lower conventional thinking styles (X+%) in offenders compared to nonoffenders. Those with an Extratensive style (n=31) showed significantly higher distorted thinking when compared to the Introversive (n=81), Ambitent (n=73), and Avoidant (n=50) coping styles. This study suggests that offenders display significantly higher distorted thinking styles than do nonoffenders. Possible reasons for these discrepancies and the role of coping styles in abusive behaviors were discussed. (c) 2007 Wiley Periodicals, Inc.

The author offers an account of his evolving relationship with the Rorschach test which for over 20 years as a private practice psychologist, he used in his clinical practice with the intent of mining patients' psyches for useful information about personality organization and functioning. Coinciding with having found himself on the homestretch of analytic training and during a time when he desired clarity on how Rorschach assessment and Jungian analysis could fruitfully merge, there was an unexpected shift in emphasis wherein the Rorschach suddenly became a method for looking at himself as well. This challenge to identify and integrate aspects of self hitherto neglected was found to enrich his clinical practice. An historical perspective on this experience is offered which highlights the enigmatic relationship that existed between Carl Jung and Hermann Rorschach. The proverbial question of 'What might this be?' has been asked when administering the Rorschach for nearly a century. From an analytic perspective, the question is more fully and meaningfully asked when the person doing the asking has also been willing to step in, look around, and take notice of what happens. © 2018, The Society of Analytical Psychology.

Recently, Hartmann and Hartmann (2014) found that psychiatric outpatients, both with and without access to Internet-based information about the Rorschach Inkblot Method (RIM; Weiner, 2003 ) and the MMPI-2 (Butcher, Dahlstrom, Graham, Tellegen, & Kaemmer, 1989 ), were unable to imitate healthy test performance on these tests. We replicated the study by administering the RIM and the MMPI-2 to 63 incarcerated violent offenders using similar testing conditions. As in the previous study, comparisons were made not only among the 3 subgroups of incarcerated offenders, but also between these offender groups and the group of nonpatients examined in the previous study. On the RIM, Internet-coached and uncoached "faking good" offenders produced records with significantly higher F% and X-% and significantly lower M, m, SumC, X+%, P, AG, and COP than nonoffenders under standard instructions (effect sizes between d = 0.24 and d = 2.39). For AgC, AgPot, AgPast, and TCI% there were no significant differences between the faking offenders and the nonoffenders under standard instructions. On the MMPI-2 clinical scales, there were no significant differences between the faking good groups and the nonoffenders under standard instructions, except on Hs, Pd, and Sc. Both faking groups were identifiable by their high L scale scores. Although both faking groups managed to avoid giving responses with aggressive and generally psychopathological content on the RIM, they were unable to produce test profiles demonstrating healthy test performance on any of the tests; nevertheless, Internet-based test information might weaken test validity.

Results of post-test psychological examinations of the crewmen from the 90-day manned test of an advanced regenerative life support system

The following material presents the results of two temporally remote administrations of an identical projective personality assessment device (Rorschach Inkblot) using crew members aboard the 90-day test. The first administration took place during preselection crew psychodiagnostic testing in the period extending from mid-December 1969 through mid-January 1970. Second administration took place in late May and early June, 1971, approximately one year after termination of the test. During the 90-day program duration, the subjects participated in the crew training program, were selected and served as onboard crew during the 90-day test. The testing was undertaken in order to determine the character and extent of change (if any) in basic personality dynamics accompanying or caused by participation in the 90-day test program. Results indicate that significant personality changes occurred in three of the four onboard crew members. A detailed discussion of the results is provided. Objective scores which served as the basis for the discussion are presented in the Appendix.

Constructivism and the projective assessment of meaning in Rorschach administration.

PubMed

Raskin, J D

2001-08-01

Constructivist perspectives on the Rorschach are outlined. I discuss ways in which constructivism complements and adds to existing Rorschach methodologies. It is suggested hat the constructivist emphasis on personally and socially constructed meanings is very consistent with many of the ways the Rorschach has been used and resonates with recent emphases on the Rorschach as a representational task. Furthermore, constructivist perspectives on Rorschach also provide an opportunity to supplement Exner's (1993, 1995) efforts to standardize and norm the Rorschach in a way that maintains the instrument's historic and admirable attention to relational elements of assessment and psychotherapy. I present a variety of meaning-based techniques for conducting Rorschach assessment, incorporating both the constructivist and social constructionist perspective.

A sample (n = 141) of Danish nonpatients 25-50 years of age, never hospitalized with a psychiatric diagnosis and currently employed, was demographically representative of two geographical areas of Copenhagen with different social strain. The sample, as well as 45 persons not currently employed, was tested with the Rorschach (Exner, 1995), MMPI-2 (Butcher, Dahlstrom, Graham, Tellegen, & Kaemmer, 1989), Word Association Test (Ivanouw, 1999b), WAIS Comprehension subtest (Hess, 1974), and SCL-90-R (Olsen, Mortenson, & Bech, 2006). Half of the persons contacted volunteered for the study. There was no difference in rate of volunteering between a standard no-feedback condition and a feedback condition; the latter, however, tended to attract more psychologically resourceful persons. The employed persons tended to appear healthier than the not employed. Response style of the subjects, quality of the Rorschach protocols, reliability of scoring, and the effect of the data being grouped on geographical area and examiner were examined. Form level, color, texture, cooperative movement, and EA were lower than in the Comprehensive System (CS; n = 450) sample, but higher than in nine international nonpatient Rorschach studies. Unique for the Danish sample was a low number of animal movement answers. The Rorschach data showed women to be healthier than men. Differences in Rorschach variables based on educational level were small.

Psychoanalytic theories suggest that color perception on the Rorschach relates to affective modulation. However, this idea has minimal empirical support. Using a clinical sample, the authors explored the cognitive and clinical correlates of Rorschach color determinants and differences among four affective modulation subtypes: Controlled, Balanced, Under-Controlled, and Flooded. Subtypes were differentiated by measures of affective regulation, reality testing/confusion, and personality traits. Initial support for the relationship of chromatic color response styles and affective modulation was found.

This study examined the possible influence of audio and video recording of personality assessment measures on anxiety. Undergraduate students in psychology were randomly assigned to Audiotape, Videotape, or Control conditions and given the State-Trait Anxiety Inventory and Rorschach Inkblot Method. A one-way multivariate analysis of variance indicated no significant differences among these conditions on the Spielberger, et al. State-Trait Anxiety Inventory, A-State scale, and five Rorschach measures of situational anxiety. Tape-recording itself did not seem to affect the anxiety indices of these frequently used personality assessments.

The role of verbalization in the Rorschach response process: a review.

Gold, J M

1987-01-01

Traditional Rorschach theory has consistently overlooked the linguistic aspect of the response process. Most conceptualizations focus on the perceptual and cognitive aspects of the process, never examining the subject's need to find a linguistic representation for the inner, perceptual process. This review examines the traditional formulations and suggests that new research from information-processing, neuropsychological, and dual-coding memory theory paradigms offer new possibilities for Rorschach research that would incorporate an appreciation of the unique cognitive demand of the test--the linking of percept with language.

Convergence of self-report scales and Rorschach indexes of psychological distress: the moderating role of self-disclosure.

2008-01-01

In this study, we addressed the weak associations found in research between self-report measures and the Rorschach test (Exner, 1978, 1991), from the perspective of Bornstein's (2002) "process dissociation framework." Specifically, in the study, we focused on the associations between self-report measures of psychological distress and their corresponding Rorschach indexes while inspecting the moderating role of self-disclosure. A total of 59, nonpatient Israeli adults participated in a 2-session study. In the first session, they completed self-report scales measuring self-disclosure and psychological distress (suicidality, depression, and loneliness). In the second session, the Rorschach test was administered and coded. The participants were divided into high and low self-disclosure groups. A convergence between self-report and Rorschach measures of psychological distress was found only among high self-disclosers. In the discussion, we address the theoretical and clinical implications of these findings.

Malingering dissociative identity disorder: objective and projective assessment.

Labott, Susan M; Wallach, Heather R

2002-04-01

Verification of dissociative identity disorder presents challenges given the complex nature of the illness. This study addressed the concern that this disorder can be successfully malingered on objective and projective psychological tests. 50 undergraduate women were assigned to a Malingering or a Control condition, then completed the Rorschach Inkblot Test and the Dissociative Experiences Scale II. The Malingering group were asked to simulate dissociative identity disorder; controls received instructions to answer all materials honestly. Analysis indicated that malingerers were significantly more likely to endorse dissociative experiences on the Dissociative Experiences Scale II in the range common to patients with diagnosed dissociative identity disorder. However, on the Rorschach there were no significant differences between the two groups. Results suggest that the assessment of dissociative identity disorder requires a multifaceted approach with both objective and projective assessment tools. Research is needed to assess these issues in clinical populations.

Gender identity disorder (GID) is a mental disorder in which gender identity is incongruent with the anatomical sex, in the absence of any clear and defined genetic or biological alteration. The diagnosis of GID as well as the assessment of patient eligibility for sex reassignment surgery (SRS) are prerequisite to the legal recognition procedure. The aim of this study was to evaluate the usefulness of the Rorschach test in differential diagnosis determination and primarily in providing information on patient eligibility for SRS, in the framework of the clinical, therapeutic and forensic psychometric and psychodiagnostic assessment, and according to the World Professional Association for Transgender Health (WPATH) criteria. For this purpose we analysed the Rorschach test of 47 patients (33 GID and 14 GID NAS). Results show that GID NAS patients have greater difficulties in stress control and less adaptability, which could lead to disorganisation, impulsiveness, behavioural disorders, as well as higher levels of situational and chronic stress, with altered thought patterns and uncontrolled ideation, a higher frequency of thought disorders and disturbed relations, with lower quality and less adaptive interpersonal relationships, which are characterized by dependency and aggressive behaviours. This research shows that the Rorschach test cannot be used alone in the determination of the differential diagnosis between GID and GID NAS in the diagnosis and evaluation of patient eligibility for SRS, especially when comparing groups which do not shows significant differences in the prevalence of the main psychopathological disorders.

Rorschach assessment of cognitive impairment from an object relations perspective.

PubMed

Lerner, P M

1996-01-01

In 1986, H. Lerner and P. Lerner proposed an object relations model of thinking that integrated Piaget's theory of early cognitive development with Mahler's theory of separation-individuation. They identified three distinct, interdigitated stages, outlined the cognitive task for each stage, detailed the necessary role and function of the stage-specific caregiving object, and suggested potential cognitive impairments associated with the object not fulfilling its function. Herein, this conceptual model is extended to the Rorschach. Rorschach indices of cognitive impairments associated with each stage were developed. The indices are then applied to the Rorschach records of children who were selected as prototypical of specific developmental disorders.

Rorschach missing responses--is this more than nothing?

PubMed

King, M G

2014-01-01

The Rorschach has been demonstrated as a suitable tool for investigating otherwise hidden psychological aspects of sex offenders: sex-related responses are more common. The present paper looks at the established tendency of some clients to minimise their overall Rorschach responding, the linking of this response restraint to particular Rorschach profiles, and the sparse but consistent literature which casts doubt on the proposition that Examiner enthusiasm will cause the minimising client to provide more responses which divulge additional information. In the case of sex offenders, with so much to hide, it is proposed that there may be extensive filtering of responses even among those giving more than "normal" sex-related responses. "What the client did not say", and the corresponding "missing" Rorschach responses in the case of sex offenders is discussed in the light of an individual case: (a sex offender with undue interest in young boys' penii) where "sex-like" images were specifically targeted, but never named as such. The exciting prospect of inferring what the client could have said and thus generating the content of missing responses, whether or not response filtering produced numerical minimisation, must be balanced against the risk of naked men and women (and their genitalia) representing nothing more than an artefact of the clinician's own making--"ce qui n' est pas le cas".

Clinical utility of the Rorschach with African Americans.

Presley, G; Smith, C; Hilsenroth, M; Exner, J

2001-12-01

In this study we sought to identify Rorschach differences between African Americans and White Americans and to understand these differences within a social and cultural framework. Data from the Exner (1993) Comprehensive System normative sample (N = 700) was used to form a group of 44 African Americans and 44 White Americans matched for age, sex, education, and socioeconomic status. Twenty-three Rorschach variables were chosen a priori and group differences were analyzed. The only clinically significant difference found was that African Americans offered significantly less cooperative movement. This lower frequency of cooperative movement may suggest African Americans do not anticipate cooperative interactions with others as a routine event. This may reflect a shared feeling among African Americans that most members of our society are less likely to be sensitive to or responsive to their needs relative to others. However, the study demonstrates a striking similarity between the groups, supporting the clinical use of the Rorschach with African Americans.

2002-08-01

In order to understand relationships between scanning behaviors, characteristics of visual stimuli and the clinical symptoms in schizophrenia, eye movements of 37 schizophrenic patients and 36 controls were recorded using an eye-mark recorder during a free-response period in a Rorschach test. Four cards (I, II, V and VIII) were used. Data were analyzed during 15 s from the presentation of each card. For all cards, the number of eye fixations and the number of eye fixation areas were fewer, and total scanning length and mean scanning length were shorter for schizophrenic patients than for controls. For card II, in the non-popular response group, eye fixation frequency upon area 5 + 6 (red) was higher for schizophrenic patients. For card VIII, in the popular response group, eye fixation frequency upon area 5 + 6 (pink) was lower for schizophrenic patients. For cards II and VIII, the number of eye fixations was inversely correlated with negative symptoms. For card II, total scanning length tended to be inversely correlated with negative symptoms, and mean eye fixation time was correlated with negative symptoms. The number of eye fixation areas was inversely correlated with positive symptoms. For card VIII, eye fixation frequency in a stimulative area tended to be correlated with positive symptoms. Scanning behaviors in schizophrenic patients are affected by characteristics of visual stimuli, and partially by clinical symptoms.

The aim of this study was to analyze the role of the imaginary and its link with reality among 30 subjects treated by methadone. The Rorschach test was proposed to 30 heroin addicts treated by methadone, over an average 7 months. The formal answers (used preferentially in the 30 results, though often inappropriately) and socializing landmarks involving considerable individual investment, we were able to identify two ways of working within the same protocol. The first relies most on conformity and adaptation and tries to put the imaginary aside. The second is a more projective, unorganized approach evidencing the influence of the imaginary. This specific imaginary activity could not be assimilated with the traditional "lack of fantasy" observed in heroin addicts. It would be interesting to examine the course of this approach over a longer period.

PubMed

Kostogianni, N; Andronikof, A

2014-02-01

According to empirical literature, low self-esteem is highly correlated to behavioural and emotional problems in gifted children and adolescents. Since self-esteem is an indicator of social and emotional adjustment, it would be interesting to better understand the meaning of this construct, as it is evaluated explicitly with the use of self-report questionnaires. In order to explore the psychological processes underlying the explicit self-esteem, we studied the relation of a self-report questionnaire and an indirect measure of self and interpersonal perception using the Rorschach Comprehensive System (CS). The participants were 93 children, aged between 9 and 15 years old, with an IQ≥130. They were attending regular classes (no curriculum difference). Self-esteem was evaluated using the Coopersmith Self-Esteem Inventory (SEI). We used the Rorschach CS measures of self and interpersonal perception. The results showed no significant correlation between self-esteem and high IQ. A negative correlation between self-esteem evaluated on the SEI and the Rorschach Vista responses was found, which reflected self-critical introspection and painful self-appraisal. Then a positive correlation was observed between self-esteem and reflection answers on the Rorschach (Fr+rF>0), which are related to narcissistic-like features of personality. We also found a positive correlation between self-esteem and the Rorschach egocentricity index (EGO), which provides an estimate of self-concern. Finally, the strongest correlation was found between self-esteem and the dominance of good over poor human representations (GHR>PHR), which reveals effective interpersonal behaviour. The psychological processes which seem to be related to low self-esteem in gifted children and adolescents are maladaptive interpersonal behaviours, painful experience of introspection focusing on perceived negative aspects of the self, absence of narcissistic-like features of the personality and low self-concern.

This study is a part of our series of studies of nonpatient, Japanese children. In total, 346 children were administered the Rorschach. Thirty-two children had fewer than 10 responses, 112 children had more than 10 but fewer than 14 responses, and 12 children were maladjusted or mentally retarded, for a total of 156. In this study, we analyzed the remaining 190 children not excluded by the above criteria in the following age groups: 5 years (n = 24), 8 years (n = 43), 9 years (n = 42), 12 years (n = 42), and 14 years (n = 39). Japanese children showed few responses generally, with an average of 18 ~ 20 responses. In addition to having fewer responses, other features of Japanese children are high Lambda, low EA, very high X-%, and low X+%. The fact that the Rorschach test depends on verbal expression may be one factor in all these features, and we should consider this study in view of these Japanese cultural factors. Interrater reliability findings and Rorschach Comprehensive System (CS; Exner, 1995; Matsumoto, 2003; Matsumoto et al., 2002) data are presented.

The Rorschach texture response: a construct validation study using attachment theory.

Cassella, Michael J; Viglione, Donald J

2009-11-01

Using attachment theory, in this research, we explored the construct validity of the Rorschach (Exner, 1974) Texture (T) response as a measure of interpersonal closeness and contact. A total of 40 men and 39 women completed the Rorschach and 2 attachment inventories. Their romantic partners also completed an informant version of the attachment measures. Attachment styles were measured by factor scores involving both self-report and partner report. Results indicate that attachment theory, as a broad conceptual framework, is associated with T. Specifically, T = 1 is most closely associated with a secure attachment style, T > 1 with aspects of the preoccupied style, and T = 0 with aspects of the avoidant style and an absence of secure attachment. Needs for closeness and contact associated with T can be couched within an adult attachment theory, but in this study, we did not test for problematic aspects of insecure attachment. Gender is a complicating factor and deserves more study.

The Scientific Status of Projective Techniques.

PubMed

Lilienfeld, S O; Wood, J M; Garb, H N

2000-11-01

Although projective techniques continue to be widely used in clinical and forensic settings, their scientific status remains highly controversial. In this monograph, we review the current state of the literature concerning the psychometric properties (norms, reliability, validity, incremental validity, treatment utility) of three major projective instruments: Rorschach Inkblot Test, Thematic Apperception Test (TAT), and human figure drawings. We conclude that there is empirical support for the validity of a small number of indexes derived from the Rorschach and TAT. However, the substantial majority of Rorschach and TAT indexes are not empirically supported. The validity evidence for human figure drawings is even more limited. With a few exceptions, projective indexes have not consistently demonstrated incremental validity above and beyond other psychometric data. In addition, we summarize the results of a new meta-analysis intended to examine the capacity of these three instruments to detect child sexual abuse. Although some projective instruments were better than chance at detecting child sexual abuse, there were virtually no replicated findings across independent investigative teams. This meta-analysis also provides the first clear evidence of substantial file drawer effects in the projectives literature, as the effect sizes from published studies markedly exceeded those from unpublished studies. We conclude with recommendations regarding the (a) construction of projective techniques with adequate validity, (b) forensic and clinical use of projective techniques, and (c) education and training of future psychologists regarding projective techniques. © 2000 Association for Psychological Science.

On the integration of personality assessment methods: the Rorschach and MMPI.

PubMed

Meyer, G J

1997-04-01

Despite being the most studied and used personality assessment tools, data from the Rorschach and MMPI generally disagree (Archer & Krishnamurthy, 1993a, 1993b). Independence is proposed to result from at least 3 factors: (a) the methods tap unique levels of personality, (b) personality has a complex organization, and (c) response styles generate considerable method variance that must be considered in nomothetic research. These ideas led to 5 hypotheses, each of which received support. Rorschach and MMPI response styles are uncorrelated, although response styles are quite consistent within a method family. MMPI-2 and Rorschach constructs of dysphoria, psychosis, or wariness are uncorrelated when response styles are ignored. However, robust convergent validity is evident when patients have similar response styles on each method (e.g., for dysphoria, M r = .59) and dysphoria is expressed in opposing ways on each method when response styles are discordant (i.e., M r = -.54). Data from the latter analyses were correlated with genuine clinical phenomena and implications were discussed for clinical practice and research.

Differentiating psychotic patients from nonpsychotic patients with the MMPI-2 and Rorschach.

The goal of this study was to examine the incremental validity and the clinical utility of the Minnesota Multiphasic Personality Inventory-2 (MMPI-2; (Butcher, Dahlstrom, Graham, Tellegen, & Kaemmer, 1989) and Rorschach (Rorschach, 1942) with regard to differential diagnosis in a sample of adult inpatients with a primary psychotic disorder or a primary mood disorder without psychotic features. Diagnostic efficiency statistics have suggested that the Rorschach Perceptual Thinking Index (PTI; Exner, 2000a, 2000b) was better than MMPI-2 scales in discriminating psychotic patients from nonpsychotic patients. We compared the 84% overall correct classification rate (OCC) for the PTI to an OCC of 70% for the MMPI-2 scales. Adding the MMPI-2 scales to the PTI resulted in a decrease in OCC of 1%, whereas adding the PTI to the MMPI-2 resulted in an increase in OCC of 14%. Sensitivity, specificity, positive predictive power, negative predictive power, and kappa were equal or higher with only the PTI in the model.

Are Rorschach Responses Influenced by Society's Change?

Based on the general belief that people "normally" see male figures on Rorschach Card III and females on Card VII; to see the opposite, according to some, would indicate a confusing of sex roles. This study makes two comparisons: age and time changes of individual responses to these cards in different decades. (DEP)

A Rorschach investigation of defensiveness, self-perception, interpersonal relations, and affective states in incarcerated pedophiles.

PubMed

Bridges, M R; Wilson, J S; Gacono, C B

1998-04-01

Rorschach protocols of 60 incarcerated men who met the Diagnostic and Statistical Manual of Mental Disorders (4th ed. [DSM-IV]; American Psychiatric Association, 1994) criteria for Pedophilia were compared to those of 60 incarcerated men with no history of sex offenses (matched for age, education, and race). Comprehensive System Rorschach variables (Exner, 1991) were selected based on both psychodynamic and cognitive-behavioral models of pedophilia. Pedophiles' Rorschachs (a) contained significantly more responses and were more likely to reveal signs of (b) anxiety and helplessness, (c) painful introspection, (d) distorted views of others, and (e) primitive dependency needs than the comparison group's Rorschachs. Like other incarcerated men, the pedophiles exhibited disturbances in self-worth (either poor self-esteem or excessive self-focus), tendencies to abuse fantasy and avoid emotionally tinged stimuli, and chronic oppositionality and hostility. Pedophiles possess many core personality features associated with Narcissistic Personality Disorders, but are less well defended against feelings of vulnerability and painful introspection than other incarcerated men. Like Antisocial Personality Disorder patients (Gacono & Meloy, 1994), our pedophiles and nonpedophile offenders showed signs of impaired attachment and, in the context of incarceration, failed narcissism.

The laugh of Satan: a study of a familial murderer.

PubMed

McCully, R S

1978-02-01

A teenage murderer who killed his mother, his tiny half-brother, and his step-father was studied through the imagery he associated to three different editions of inkblots. These sets included the Rorschach, Behn-Rorschach, and Ka-Ro plates. The data were used to theorize about clues, dynamics, and diagnosis in this extreme case of adolescent violence. Family background and developmental history are included. The author takes the position that a conventional analysis of these data alone is not sufficient to fully understand familial murderers. Several of C.G. Jung's concepts, notably his view about the power of shadow-projections to influence conscious percepts and his philosophy about evil as a collective phenomenon, were used to speculate about ways we might extend our understanding of this subject's extreme form of violence. Defining the archetype as an energy-complex, the discussion theorized about possible ways different forms of paranoid ideation may arise.

Solomon design analysis of multiple-choice Rorschach animal content.

PubMed

Feigenbaum, D; Costello, R M

1975-10-01

The Solomon four-group design was used to study the effects of a persuasive message on a selected multiple-choice Rorschach index--animal content. The independent variable elicited behavior in a predictable manner. Pretesting as a main effect was not significant, but as an interactional effect obviated the effect of the persuasive message. Although knowledge of test rationale can elicit behavior that conforms to experimental demand characteristics, some subjects nonetheless acted in defiance of such information. A condition for defiance in this experimental arrangement, however, was pretesting. Other possibilities regarding the study of compliance behavior and the use of pathognomonic indicators were suggested. Ethical issues were raised.

A Rorschach comparison of psychopaths, sexual homicide perpetrators, and nonviolent pedophiles: where angels fear to tread.

PubMed

Gacono, C B; Meloy, J R; Bridges, M R

2000-06-01

Nonsexually offending psychopaths (N = 32) were compared to sexual homicide perpetrators (N = 38) and nonviolent pedophiles (N = 39) on select Comprehensive System Rorschach variables (Exner et al., 1993). Results indicate similarities among the groups in pathological narcissism, formal thought disorder, and borderline level reality testing. Nonsexually offending psychopaths are distinguished by their lack of interest in and attachment to others and their seemingly conflict-free internal world. While both sexually deviant groups evidenced interest in others and appear to experience a very dysphoric internal world, the sexual homicide perpetrators are distinguished by high levels of obsessional thought and an inability to disengage from environmental stimuli. Pedophiles show significantly more characterological anger, which may stem from their general inadequacy, cognitive rigidness, less alloplastic (acting out) style, and their introversive inability to gratify their needs. Rorschach differences add to our understanding of sexual deviation and violence among these three groups.

Rorschach oral dependency in psychopaths, sexual homicide perpetrators, and nonviolent pedophiles.

Huprich, Steven K; Gacono, Carl B; Schneider, Robert B; Bridges, Michael R

Rorschach Oral Dependency scores (Masling, Rabie, & Blondheim, 1967) were compared among nonsexually offending psychopaths (NSOPs, n = 32), sexual homicide perpetrators (SHPs, n = 38), and non-violent pedophiles (NVPs, n = 39) as initially reported by Gacono, Meloy, and Bridges (2000). The aggressive special scores of Gacono and Meloy (1994; Gacono, unpublished doctoral dissertation, 1998) were also scored and compared with ROD scores. Consistent with theory and predictions, NVPs were found to have significantly higher levels of oral dependency scores than NSOPs or SHPs. Additionally, there was a high degree of association between oral dependency and aggression in the SHP and NSOP groups. These Rorschach differences support the validity of the ROD as an implicit measure of dependency and add to the understanding of the dynamics that fuel sexually deviant violence.

A commentary on Adolf Eichmann's Rorschach.

McCully, R S

1980-06-01

A Rorschach was administered to Adolf Eichmann in Jerusalem in 1961 at the time of his trial for war crimes. The recent publication of this protocol offers an opportunity to compare his personal world against opinions formed about him by observers at his trial. Various professionals certified Eichmann as a banal, ordinary man, and a societal theory was proposed about Nazism based in part on impressions of Eichmann as an uncomplicated man. This commentary examines Eichmann's protocol and provides an opinion that in several important respects his record includes features uncharacteristic of an ordinary, banal mind.

Self-reported attachment patterns and Rorschach-related scores of ego boundary, defensive processes, and thinking disorders.

PubMed

Berant, Ety; Wald, Yaarit

2009-07-01

In this study, we addressed associations between self-reported attachment scales (anxiety and avoidance) and Rorschach (1921/1942) indexes indicating ego-boundary perception (barrier and penetration), use of projective identification, devaluation and splitting defenses, and Comprehensive System (Exner, 2005) scores that represent boundary blurring (incongruous and fabulized combinations). In this study, we extended the sample and findings described by Berant, Mikulincer, Shaver, and Segal (2005) using a nonclinical sample of 89 Israeli adults. We found significant associations between attachment orientations and Rorschach indexes dynamically related to anxiety. We also found a trend toward association between attachment orientation and avoidance. We discuss the theoretical and clinical implications of these findings.

Schultz, Douglas S; Brabender, Virginia M

2013-01-01

To determine the effects of reading the Wikipedia article on the Rorschach on Comprehensive System variables, participants in this study (recruited from parent-teacher associations, online message boards, and graduate schools; N = 50) were provided with either a copy of the Wikipedia article on the Rorschach (from April 2010) or an irrelevant article, then administered the Rorschach and instructed to "fake good." Monetary incentives were used to increase motivation to dissimulate. Initial results indicated that participants given the Wikipedia article produced a lower number of responses (R) and had higher scores on Populars, X+%, XA%, and WDA% as compared to controls. However, post-hoc analyses revealed that when the influence of Populars was controlled, significant differences for X+%, XA%, and WDA% disappeared. No significant differences were found for Form%, Zf, Blends, or PER, although post-hoc analyses controlling for differences in R revealed a significant difference between groups on Zf%. Limitations of the study and implications for clinical and forensic practice are discussed.

In this study, we examined global treatment outcomes during 16 months of intensive, psychodynamic treatment for 77 inpatients suffering from treatment-refractory disorders. Hypotheses based on the phase model of treatment change (Howard, Lueger, Maling, & Martinovich, 1993; Howard, Moras, Brill, Martinovich, & Lutz, 1996) were supported in the study results. Diagnostic and Statistical Manual of Mental Disorders (4th ed.; American Psychiatric Association, 1994) Axis V scales assessing behavioral functioning demonstrated large and medium effect size change, whereas stable, enduring personality functioning assessed by psychoanalytic Rorschach scales and the Social Cognition and Object Relations Scale (Westen, 1995) for the Thematic Apperception Test (Murray, 1943) demonstrated small and medium effect size change. We also report assessment of reliable change index and clinical significance. The ecological validity of Rorschach measures is supported by significant validity coefficients (in the hypothesized directions) between implicit measures of personality functioning and behavioral ratings.

Objective: This study aimed to provide a normative study documenting how 114 five-seven year-old non-‎patient Iranian children respond to the Rorschach test. We compared this especial sample to ‎international normative reference values for the Comprehensive System (CS).‎ Method: One hundred fourteen 5- 7- year-old non-patient Iranian children were recruited from public ‎schools. Using five child and adolescent samples from five countries, we compared Iranian ‎Normative Reference Data- based on reference means and standard deviations for each sample.‎ Results: Findings revealed that how the scores in each sample were distributed and how the samples were ‎compared across variables in eight Rorschach Comprehensive System (CS) clusters. We reported ‎all descriptive statistics such as reference mean and standard deviation for all variables.‎ Conclusion: Iranian clinicians could rely on country specific or “local norms” when assessing children. We ‎discourage Iranian clinicians to use many CS scores to make nomothetic, score-based inferences ‎about psychopathology in children and adolescents.‎ PMID:27928247

Potential Projective Material on the Rorschach: Comparing Comprehensive System Protocols to Their Modeled R-Optimized Administration Counterparts.

PubMed

Pianowski, Giselle; Meyer, Gregory J; Villemor-Amaral, Anna Elisa de

2016-01-01

Exner ( 1989 ) and Weiner ( 2003 ) identified 3 types of Rorschach codes that are most likely to contain personally relevant projective material: Distortions, Movement, and Embellishments. We examine how often these types of codes occur in normative data and whether their frequency changes for the 1st, 2nd, 3rd, 4th, or last response to a card. We also examine the impact on these variables of the Rorschach Performance Assessment System's (R-PAS) statistical modeling procedures that convert the distribution of responses (R) from Comprehensive System (CS) administered protocols to match the distribution of R found in protocols obtained using R-optimized administration guidelines. In 2 normative reference databases, the results indicated that about 40% of responses (M = 39.25) have 1 type of code, 15% have 2 types, and 1.5% have all 3 types, with frequencies not changing by response number. In addition, there were no mean differences in the original CS and R-optimized modeled records (M Cohen's d = -0.04 in both databases). When considered alongside findings showing minimal differences between the protocols of people randomly assigned to CS or R-optimized administration, the data suggest R-optimized administration should not alter the extent to which potential projective material is present in a Rorschach protocol.

Rorschach cognitive developmental indices of mentally retarded persons: a comparison with scores on Wechsler Intelligence Scale for children-revised.

1997-08-01

In a sample of 55 mentally retarded subjects (M age = 14 yr., 1 mo.) the relations between some perceptual and cognitive Rorschach indices, including the Becker's Genetic Level Score, and Wechsler Scale scores were studied. The mean Developmental Score did not increase across ages and was higher for girls than for boys, while Verbal and Performance IQs were lower for girls. The correlations confirm the hypothesis that for mentally retarded persons WISC-R scaled scores and Rorschach cognitive indices are different measures of intellective functioning. The findings are discussed with reference to the assessment and rehabilitation of retarded subjects.

Degree of body weight in obesity and Rorschach personality aspects of mental distress.

Elfhag, K; Rössner, S; Carlsson, A M

2004-03-01

To study the relationship between degree of obesity and personality measures of mental distress. The Rorschach method (Comprehensive System) and the Beck Depression Inventory. General descriptors were also included. Participants were 120 obese patients with a mean body mass index (BMI) of 41 (+/- SD 6) kg/m2. Depression, stress or psychopathology such as distortions in perception and cognitions were not related to the degree of obesity. Body concern and body-related anxiety (An+Xy) were more common in relatively lower degrees of obesity. According to general descriptors heavier patients had lower educational and socio-economic level, and more bodily pain problems. Depression was not related to body weight, in spite of findings of more depression in obesity compared to normal weights. Other factors than severity of obesity would account for the mental distress in obese patients. The differences in body concern and anxiety in varying degrees of obesity could be related to the social and educational context, where attitudes toward obesity differ. Less Rorschach signs of body concern in the morbidly obese contrasted with more self-reported bodily pain problems.

Concurrent validity of the Wheeler signs of homosexuality in the Rorschach: P (Ci/Rj).

Stone, N M; Schneider, R E

1975-12-01

The Rorschach protocols of 43 males consecutively admitted to a university outpatient clinic were scored for frequency of the 20 Wheeler signs of homosexuality. Based on case history data, patients were assigned to homosexual, sex-role disturbed, or normal-control groups. In addition to the traditional group comparison the results were analyzed to yield P (Ci/Rj); that is, the probability of criterion group membership given test indicator. Both the homosexual and sex-role disturbed group displayed significantly more Wheeler signs than normals. Furthermore, given a Wheeler sign score of 15%, .75 of the predicted-homosexual group would be correctly classified compared to a .21 baserate prediction. It was suggested that expressing results as P (Ci/Rj) provides information more relevant to the clinician than is provided by the traditional practice of reporting significant differences between groups.

The effect of color on the production of responses to Rorschach cards VIII, IX, and X in age groups of 11-12 and 15-16 years.

PubMed

Silva, Danilo R; Ferreira, Ana Sousa

2014-01-01

The effect of color on the production of responses to the Rorschach task has been considered by investigators from 2 different positions: (a) that color has little effect on the production of responses, and (b) that color increases the number of responses. Some previous results found by the current investigators have supported the first position for the last 3 fully colored Rorschach cards (VIII, IX, and X), in children from 5 to 12 years old. Other studies of ours, however, have confirmed the second position for these same cards with a group of young adults 17 to 23 years old. As there was no increase of responses up to age 12, for this study we hypothesized a developmental effect in adolescence such that there would be an increase in the production of responses to the colored Rorschach cards at the age of 15 to 16 years, and this is what the results indicate. From a pragmatic standpoint, these results imply a revision of interpretive meaning for the Color and Affective Ratio variables in children's protocols. Our results also indicate that color cannot be regarded as a means of expression of affect at age 11 to 12 like it will be from age 15 to 16 and on.

Extrasensory Perception Experiences and Childhood Trauma: A Rorschach Investigation.

Scimeca, Giuseppe; Bruno, Antonio; Pandolfo, Gianluca; La Ciura, Giulia; Zoccali, Rocco A; Muscatello, Maria R A

2015-11-01

This study investigated whether people who report recurrent extrasensory perception (ESP) experiences (telepathy, clairvoyance, and precognition) have suffered more traumatic experiences and traumatic intrusions. Thirty-one nonclinical participants reporting recurrent ESP experiences were compared with a nonclinical sample of 31 individuals who did not report recurrent ESP phenomena. Past traumatic experiences were assessed via a self-report measure of trauma history (Childhood Trauma Questionnaire); traumatic intrusions were assessed via a performance-based personality measure (Rorschach Traumatic Content Index). Participants also completed the Anomalous Experience Inventory, the Minnesota Multiphasic Personality Inventory-2, the Dissociative Experience Scale, and the Revised Paranormal Belief Scale. The ESP group reported higher levels of emotional abuse, sexual abuse, emotional neglect, physical neglect, and traumatic intrusions. The association between ESP experiences and trauma was partly mediated by the effects of dissociation and emotional distress. Implications for health professionals are discussed. Results also showed the reliability of the twofold method of assessment of trauma.

Rorschach Assessment of Two Distinctive Personality States of a Person With Dissociative Identity Disorder.

Hartmann, Ellen; Benum, Kirsten

2017-12-13

This case study used test data from a patient with Dissociative Identity Disorder (DID; American Psychiatric Association, 2013 ) to illustrate how two main personality states of the patient ("Ann" and "Ben") seemed to function. The Rorschach Performance Assessment System (R-PAS; Meyer, Viglione, Mihura, Erard, & Erdberg, 2011 ) and the Inventory of Interpersonal Problems-Circumplex (IIP-64; Horowitz, Alden, Wiggins, & Pincus, 2000 ), administered to Ann and Ben in separate settings, exposed two diverse R-PAS and IIP-64 profiles. Ann's R-PAS profile suggested an intellectualized style of information processing with few indications of psychological problems. Ben's profile indicated severe perceptual, cognitive, and interpersonal difficulties combined with suspicion and anxiety. Ann's IIP-64 profile suggested minor interpersonal problems, whereas Ben's indicated serious relational difficulties. The findings were discussed in relation to the theory of trauma-related structural dissociation of the personality (van der Hart, Nijenhuis, & Steele, 2006 ), which implies an enduring split in the organization of the personality with more or less separate entities with their own sense of self, perception of the world, and ways of organizing emotional, cognitive, and social functions. The DID personality structure is seen as a defense strategy and as a pathway in the personality development producing serious psychological pain and symptoms.

Resiliency characteristics and Rorschach variables in children and adolescents with severe burns.

1994-01-01

Three raters classified 40 children and adolescents (ages 8 to 19 years) with severe burns who were placed in two groups designated as Resilient (N = 28) and Nonresilient (N = 12). Nine hypothesized differences in Rorschach responding between groups were developed through a review of the literature and operationalized through descriptive statements from a rating scale now being developed. The Resilient group gave more Cooperative Movement responses than the Nonresilient group (p = 0.0270), and they were more likely to have D scores that were within the normal range (p = 0.0700). The Nonresilient group had lower Egocentricity Index scores than the Resilient group (p = 0.0368) and more often had a positive Coping Deficit Index (p = 0.1285). Texture, Diffuse Shading, and Passive: Active responses appeared similar between groups. Differences found concerning Experience Actual and Z frequency were not statistically significant. Possible interventions addressing the emotional needs of burned children and adolescents such as strengthening certain personality characteristics are noted.

Nowadays, it is becoming increasingly difficult to clearly classify the issues associated with the phenomenon of gender dysphoria due to the fact that one identifies oneself in the context of increasingly fluid categories of gender identity-- an intrinsic sense of being a woman or a man. The authors present a woman whose internal problems connected with her sexuality and incomplete identification with the role attributed to her gender originate from her family history. Long-lasting, traumatic experiences of incestuous abuse and violence on the part of close relatives disturbed her development in many areas of personality and functioning. The aim of the study was to verify the hypothesis of the existence of gender identity disorder accompanied by depressive disorders. In addition to the medical history, the study of patient's problems included the following diagnostic tools: the Minnesota Multiphasic Personality Inventory (MMPI) and the Rorschach Inkblot Test in a CSR Exner system (TPA). The study revealed that as for sexual identification, the patient unambiguously identifies herself as a woman. Her behaviour to become like a man does not deny her sex, or even involve a temporary need of belonging to the opposite sex. It should be interpreted in the broader context of her traumatic experiences, not just sexual, but also concerning different aspects of a female gender role.

2017-05-01

The Rorschach-based Perceptual Thinking Index (PTI) is used to identify and rate features of psychotic disorders, but effects of antipsychotic treatment on such ratings is not clear. Accordingly, we examined potential effects of antipsychotic drugs on PTI measures in 114 patients with a psychotic or bipolar-I disorder. Use and doses of antipsychotic drugs (as chlorpromazine-equivalent [CPZ-eq] mg/day) were unrelated to PTI total or subscale scores in any diagnostic group. PTI scores were independently and significantly associated with psychotic symptomatic severity (PANSS score) and less with female sex. These findings support the validity and value of the PTI in identifying features of psychosis even in the presence of antipsychotic treatment. Copyright © 2017 Elsevier Ireland Ltd.

The literature examining primary headache, including migraine, in adolescents, has pointed out the key role played by a wide range of psychiatric disorders in reducing the patients’ quality of life. Moreover, pioneering studies showed that preexisting personality characteristics, specific emotion regulation styles and psychological-psychiatric difficulties are likely to increase the risk of the onset, maintenance, and outcome of headache. Still personality issues in migraine have been poorly studied, in particular in children and adolescents. This study aims, therefore, to investigate the specific characteristics of personality, and in particular emotion regulation and coping strategies, in adolescent with migraine, comparing them with age-matched patients with idiopathic epilepsy and healthy adolescents. 52 adolescents (age: 11–17) were assessed using a multi-method test battery, which included a self-report questionnaire (the youth self-report), a proxy-report (child behavior checklist) along with a projective personality test, the Rorschach Test, administered and scored according to the Exner comprehensive system. The results showed specific personality characteristics in adolescents with migraine, revealing a marked difficulty in modulating and regulating affections through thoughts and reflections, resorting instead to impulsive acts and maladaptive coping strategies, thus revealing a vague and immature perception of reality. Differently from adolescents belonging to the general population, but similarly to patients with epilepsy, adolescents with migraine perceive a high situational stress, probably related to the condition of suffering from chronic disease. They have, therefore, a lower self-consideration and self-esteem along with a poorer insight regarding themselves as well as the relations with others. In line with previous findings, these preliminary results suggest the need for further research on ample samples, using also standardized projective

The use of projective and psychometric psychological tests at the Department of Forensic Psychiatry in Stockholm (Huddinge), Sweden, was studied for a population of 60 men, including many patients with neuropsychological disabilities and multiple psychiatric disorders. The results showed that the use of projective tests like Rorschach, Object Relations Test, and House-Tree-Person was more frequent than the use of objective psychometric tests. Neuropsychological test batteries like the Halstead-Reitan Neuropsychological Test Battery or Luria-Nebraska Neuropsychological Battery were not used. The majority of patients were, however, assessed by intelligence scales like the WAIS-R. The questionable reliability and validity of the projective tests, and the risk of subjective interpretations, raise a problem when used in a forensic setting, since the courts' decisions about a sentence to prison or psychiatric care is based on the forensic psychiatric assessment. The use of objective psychometric neuropsychological tests and personality tests is recommended.

Personality Dimensions as Assessed by Projective and Verbal Instruments

This study aimed to define personality dimensions when assessed by projective and verbal instruments. The Holtzman Inkblot Test was selected to represent projective tests. The 18 scales of the California Personality Inventory (CPI) and the Rokeach Dogmatism Scale (RDS) were the objective tests used. (Author/RK)

Association between the Rorschach Ego Impairment Index and the Level of Personality Organization interview assessment in depressive and anxiety disorder patients.

The level of personality functioning, relevant for treatment planning, can be evaluated by the Rorschach Comprehensive System (CS) Ego Impairment Index-2 (EII-2) and by interview assessment of the severity of personality pathology. However, few studies on the association between these assessment methods have been reported. This study examines the strength of association between the EII-2 and its subcomponents with the interview-based Level of Personality Organization (LPO) assessment scale, and investigates their mutual associations with psychiatric symptoms, diagnoses, and history. Altogether, 315 mood or anxiety disorder outpatients without severe personality pathology were assessed with the LPO and tested with the CS, on which the EII-2 and its subcomponents (FQ-, WSum6, Critical contents, M-, PHR, GHR, and R) were calculated. Significant, but weak association between the EII-2 and the LPO was found. The WSum6, a measure of thought disorder, was the only EII-2 subcomponent significantly associated with the LPO. Both measures were consistently associated with psychiatric symptoms, diagnoses and history. The findings partially support the EII-2 and the LPO as consistently associated, relatively independent measures of the severity of personality pathology. More research on the incremental benefits of the measures is needed in clinical populations, covering non-severe and complex psychopathology. Copyright © 2012 Elsevier Ireland Ltd.

What psychological testing and neuroimaging tell us about the treatment of Posttraumatic Stress Disorder by Eye Movement Desensitization and Reprocessing.

PubMed

Levin, P; Lazrove, S; van der Kolk, B

1999-01-01

To better understand the pathophysiology and treatment of Posttraumatic Stress Disorder (PTSD), standard psychological testing, Rorschach Ink Blot testing, and neuroimaging using Single Photon Emission Computed Tomography (SPECT) were administered to subjects with PTSD prior to and following three sessions of Eye Movement Desensitization and Reprocessing (EMDR). Using this within-subject design, data from one of six subjects in our series is presented as a case report. Following EMDR, the subject experienced improvement in his level of distress, which correlated with decrements in PTSD and depressive symptomatology on psychological testing. Analysis of the Rorschach data corroborated these changes. Among other findings, the Hypervigilance Index went from positive to negative, indicating that the subject was spending less time scanning the environment for threats, and available ego resources also increased, as measured by the Experience Actual variable. Upon recall of the traumatic memory during SPECT scanning, two areas of the brain were hyperactive post-EMDR treatment relative to pretreatment: the anterior cingulate gyrus and the left frontal lobe. These changes were consistent with summed data from four out of six subjects in the ongoing study. An important implication of these findings is that successful treatment of PTSD does not reduce arousal at the limbic level, but instead, enhances the ability to differentiate real from imagined threat. The psychology and neurophysiology of PTSD are discussed in greater detail.

Extending the Rorschach trauma content index and aggression indexes to dream narratives of children exposed to enduring violence: an exploratory study.

PubMed

Kamphuis, Jan H; Tuin, Nynke; Timmermans, Marieke; Punamäki, Raija-Leena

2008-11-01

In this study, we compared dream narratives of children and adolescents living under conditions of enduring interpersonal violence (n = 220) versus those living in peaceful surroundings (n = 99) on content variables that have been associated with traumatic experiences in Rorschach (Exner, 1995) imagery. As predicted, children and adolescents living in circumstances of enduring violence reported a higher proportion of content scorable by Armstrong and Loewenstein's (1990) Trauma Content Index and a much higher proportion of aggressive objects in their dreams (AgC; Gacono & Meloy, 1994). In support of discriminant validity, no consistent group differences were observed for the relative frequencies of Animal (A), Clothing (Cg), or Cooperative movement (COP) content. The modest association between manifest dream content and psychological symptom scales suggests that the former may alternatively reflect adaptive or psychopathological processes. Our findings suggest that content analysis of dreams may be a valuable adjunct in tapping the psychological state of children traumatized by violence.

On Conducting Construct Validity Meta-Analyses for the Rorschach: A Reply to Tibon Czopp and Zeligman (2016).

2016-01-01

We respond to Tibon Czopp and Zeligman's (2016) critique of our systematic reviews and meta-analyses of 65 Rorschach Comprehensive System (CS) variables published in Psychological Bulletin (2013). The authors endorsed our supportive findings but critiqued the same methodology when used for the 13 unsupported variables. Unfortunately, their commentary was based on significant misunderstandings of our meta-analytic method and results, such as thinking we used introspectively assessed criteria in classifying levels of support and reporting only a subset of our externally assessed criteria. We systematically address their arguments that our construct label and criterion variable choices were inaccurate and, therefore, meta-analytic validity for these 13 CS variables was artificially low. For example, the authors created new construct labels for these variables that they called "the customary CS interpretation," but did not describe their methodology nor provide evidence that their labels would result in better validity than ours. They cite studies they believe we should have included; we explain how these studies did not fit our inclusion criteria and that including them would have actually reduced the relevant CS variables' meta-analytic validity. Ultimately, criticisms alone cannot change meta-analytic support from negative to positive; Tibon Czopp and Zeligman would need to conduct their own construct validity meta-analyses.

Clinical identification of compensatory structures on projective tests: a self psychological approach.

PubMed

Silverstein, M L

2001-06-01

In this article I discuss compensatory structure, a concept from Kohut's (1971, 1977) psychology of the self that is not as familiar as Kohut's other views about the self. Compensatory structures are attempts to repair selfobject failure, usually by strengthening idealization or twinship in the face of mirroring deficits. Compensatory structures, particularly their early indications, can be detected on projective tests for identifying adaptive resources and treatment potential. The clinical identification of compensatory structures on test findings is described using Rorschach and Thematic Apperception Test (Murray, 1943) content. Particular attention is devoted to the 2-part process of demonstrating first, an injury to the self, and second, how attempts to recover from such injuries can be detected on projective tests. Clinical examples are provided, and the differentiation between compensatory structures and defenses and sublimation is discussed.

A critique of Lilienfeld et al.'s (2000) "The scientific status of projective techniques".

PubMed

Hibbard, Stephen

2003-06-01

Lilienfeld, Wood, and Garb (2000) published a largely negative critique of the validity and reliability of projective methods, concentrating on the Comprehensive System for the Rorschach (Exner, 1993), 3 systems for coding the Thematic Apperception Test (TAT; Murray, 1943) cards, and human figure drawings. This article is an effort to document and correct what I perceive as errors of omission and commission in the Lilienfeld et al. article. When projective measures are viewed in the light of these corrections, the evidence for the validity and clinical usefulness of the Rorschach and TAT methods is more robust than Lilienfeld et al. represented.

Hemispheric resource limitations in comprehending ambiguous pictures.

PubMed

White, H; Minor, S W

1990-03-01

Ambiguous pictures (Roschach inkblots) were lateralized for 100 msec vs. 200 msec to the right and left hemispheres (RH and LH) of 32 normal right-handed males who determined which of two previously presented words (an accurate or inaccurate one) better described the inkblot. Over the first 32 trials, subjects receiving each stimulus exposure duration were less accurate when the hemisphere receiving the stimulus also controlled the hand used to register a keypress response (RH-left hand and LH-right hand trials) than when hemispheric resources were shared, i.e., when one hemisphere controlled stimulus processing and the other controlled response programming. These differences were eliminated when the 32 trials were repeated.

Queer signs: The women of the British projective test movement.

PubMed

Hubbard, Katherine

2017-07-01

As queer history is often hidden, historians must look for "signs" that hint at queer lives and experiences. When psychologists use projective tests, the search for queer signs has historically been more literal, and this was especially true in the homophobic practices of Psychology in the mid-twentieth century. In this paper, I respond to Elizabeth Scarborough's call for more analytic history about the lesser known women in Psychology's history. By focusing on British projective research conducted by lesbian psychologist June Hopkins, I shift perspective and consider, not those who were tested (which has been historically more common), but those who did the testing, and position them as potential queer subjects. After briefly outlining why the projective test movement is ripe for such analysis and the kinds of queer signs that were identified using the Rorschach ink blot test in the mid-twentieth century, I then present June Hopkins' (1969, 1970) research on the "lesbian personality." This work forms a framework upon which I then consider the lives of Margaret Lowenfeld, Ann Kaldegg, and Effie Lillian Hutton, all of whom were involved in the British projective test movement a generation prior to Hopkins. By adopting Hopkins' research to frame their lives, I present the possibility of this ambiguous history being distinctly queer. © 2017 Wiley Periodicals, Inc.

The affective dimension of response elicitation data: a projective measure.

PubMed

Tibon, S; Blumberg, H H

2000-03-01

In this research, the Rorschach Affective Ratio, a measure for frequency of response elicitation, was used to examine the affective dimension of response elicitation data. The purpose of this study was to apply the Rorschach Affective Ratio to an examination of the psychodynamic roots of political behavior. This measure compares the number of responses to colored cards, considered as emotional stimuli, with those revealed by the other (black and white) cards of the test. Israeli undergraduates (N = 26) completed a questionnaire composed of 20 questions about peace. Participants who were more supportive of the peace process in the Middle East were found to have a lower Affective Ratio than those who were less supportive. This result suggests that measurable affective aspects may be as important as cognitive aspects of response elicitation in understanding an individual's political attitudes.

Personality and Psychiatric Disorders in Women Affected by Polycystic Ovary Syndrome

PubMed Central

Scaruffi, Elisabetta; Gambineri, Alessandra; Cattaneo, Stefania; Turra, Jenni; Vettor, Roberto; Mioni, Roberto

2014-01-01

Background: Polycystic ovary syndrome (PCOS) is the most prevalent endocrine disorder among fertile women. Studies show reduced quality of life, anxiety, depression, body dissatisfaction, eating disorder, and sexual dysfunction, but the etiology of these disturbs remains still debated. The aim of our study is to verify whether this hyperandrogenic syndrome characterizes a strong psycho(patho)logical personality. Method: Sixty PCOS subjects (mean age 25.8 ± 4.7 years) were evaluated by anthropometric, metabolic, hormonal, clinical, and psychological parameters. After the certainty of the diagnosis of PCOS, the Rorschach test, according to Exner’s comprehensive system (CS) and the Millon Clinical Multiaxial Inventory-III (MCMI-III) were administered to each patient. The control group, on which the comparison was carried out, was composed by 40 healthy and aged compared women who were exclusively administered the Rorschach test according to CS. Results: MCMI-III evidenced axis II DSM-IV personality disorders [4.1% schizoid, depressive, sadistic, negativistic (passive–aggressive), and masochistic, 6.1% avoiding, 12.2% dependent, 20.4% histrionic, 16.3% narcissistic, 2.0% obsessive–compulsive], and axis I DSM-IV psychiatric disorders: 10.2% anxiety, 2.0% somatoform disorder and bipolar disorder, 16.3% major depressive disorder. Finally, we found 44.9% delusional disorder and 4.1% thought disorder. Rorschach test’s results show 53.1% reduced coping abilities and social skills, 55.1% depression, 30.6% perceptual distortion and cognitive slippage, 24.5% constantly alert and worry, 8.1% at risk for suicide, and finally about 50% of our patients had chronic stress. Conclusion: PCOS women have relevant personality and psychiatric disorders, when compared with normal subjects. PMID:25429283

The Impact of an Ego Depletion Manipulation on Performance-Based and Self-Report Assessment Measures.

PubMed

Charek, Daniel B; Meyer, Gregory J; Mihura, Joni L

2016-10-01

We investigated the impact of ego depletion on selected Rorschach cognitive processing variables and self-reported affect states. Research indicates acts of effortful self-regulation transiently deplete a finite pool of cognitive resources, impairing performance on subsequent tasks requiring self-regulation. We predicted that relative to controls, ego-depleted participants' Rorschach protocols would have more spontaneous reactivity to color, less cognitive sophistication, and more frequent logical lapses in visualization, whereas self-reports would reflect greater fatigue and less attentiveness. The hypotheses were partially supported; despite a surprising absence of self-reported differences, ego-depleted participants had Rorschach protocols with lower scores on two variables indicative of sophisticated combinatory thinking, as well as higher levels of color receptivity; they also had lower scores on a composite variable computed across all hypothesized markers of complexity. In addition, self-reported achievement striving moderated the effect of the experimental manipulation on color receptivity, and in the Depletion condition it was associated with greater attentiveness to the tasks, more color reactivity, and less global synthetic processing. Results are discussed with an emphasis on the response process, methodological limitations and strengths, implications for calculating refined Rorschach scores, and the value of using multiple methods in research and experimental paradigms to validate assessment measures. © The Author(s) 2015.

Basso, Elisabetta

In March 1954, Foucault visited the psychiatric asylum of Münsterlingen (Canton Thurgau), on the Swiss side of Lake Constance. Münsterlingen was the chosen place of activity for well-known psychiatrists, including Hermann Rorschach (1910-1913), and it became famous in the history of psychiatry especially through the work of Roland Kuhn, who was active in the asylum from 1939 to 1979. Kuhn was an expert in the Rorschach psycho-diagnostic test, as well as the discoverer of the first antidepressant in the early 1950s. He was also very close to Ludwig Binswanger, whose anthropological approach to mental illness had a strong influence on his own psychiatric practice. It is precisely in order to meet Kuhn and Binswanger that the young Foucault went to Switzerland, at a time when he was interested in philosophical anthropology and "existential psychopathology". Foucault's visit took place during the Carnival at the asylum, when the patients leave the hospital wearing the masks that they have made up and created. © 2017 médecine/sciences – Inserm.

An empirical study of Freud's penis-baby equation.

PubMed

Jones, R L

1994-03-01

One hypothesis of traditional psychoanalytic theory holds that a cardinal aspect of the "natural" development of femininity involves the woman's substitution of the wish for a baby in place of her original wish for a penis. The current study modified and extended earlier research examining the validity of Freud's this "penis-baby" theory. College-aged women and men were presented with either subliminal or supraliminal auditory messages concerned with either pregnancy or penetration themes. Subjects' written responses to Holtzman ink-blots, obtained both before and after exposure to an auditory message, were content-coded for phallic imagery and sexual imagery. Consistent with Freud's speculations about the phallic significance of pregnancy for women, female subjects who were exposed to the subliminal pregnancy message produced significantly more phallic imagery responses to ink-blots than did women in any of the other experimental conditions (p < .01). The phallic imagery production of males did not vary significantly as a function of message condition. Implications of these findings are discussed in the context of modern revisions to Freud's psychology of women and the current psychoanalytic conceptualization of penis envy as a highly condensed mental product with many layers of meaning.

Projective techniques and the detection of child sexual abuse.

Garb, H N; Wood, J M; Nezworski, M T

2000-05-01

Projective techniques (e.g., the Rorschach, Human Figure Drawings) are sometimes used to detect child sexual abuse. West recently conducted a meta-analysis on this topic, but she systematically excluded nonsignificant results. In this article, a reanalysis of her data is presented. The authors conclude that projective techniques should not be used to detect child sexual abuse. Many of the studies purportedly demonstrating validity are flawed, and none of the projective test scores have been well replicated.

Communication Deviance in parents of families with adoptees at a high or low risk of schizophrenia-spectrum disorders and its associations with attributes of the adoptee and the adoptive parents.

2011-01-30

Communication Deviance (CD) in rearing parents is a known indicator of a psychopathology risk in the offspring, but the direction of the effects of these two factors on each other has remained an unresolved question. The purpose of the present study was to clarify this issue by assessing the relationship of CD in adoptive parents with certain attributes of the adoptee and adoptive parents themselves. The subjects were 109 adoptees at a high or low risk of schizophrenia-spectrum disorders and their adoptive parents. Communication Deviance was measured in individual, spouse and family Rorschach situations. Thought disorders in the adoptees were assessed using the Thought Disorder Index. The variability of CD in the adoptive parents in individual Rorschach situations was not significantly explained by any characteristics of the child. The variability in parental CD in family Rorschach situations was most closely associated with the characteristics of the parents themselves. The results strongly support the hypotheses that the frequency of Communication Deviance is an enduring trait rather than a fluctuating state and that frequent CD in parent's speech may impair the growing child's cognitive development and predispose him/her to schizophrenia-spectrum disorders.

Posttraumatic stress disorder in former 'comfort women'.

This study investigated the mental health of former 'comfort women' who serviced the Japanese Imperial Military during the Second World War. We evaluated 26 former comfort women's life histories, cognitive functioning, DSM-IV diagnosis of posttraumatic stress disorder (PTSD), depression, paranoid state, anger, and Rorschach test results, and compared the data with those of 24 healthy women. Cognitive functioning was not significantly different between former comfort women and the comparison group. All 26 former comfort women had undergone traumatic experiences such as sexual slavery and had suffered PTSD symptoms at least once in their lives. Of the 26, 8 (30.8%) were diagnosed as having PTSD, as opposed to none in the comparison group. The women's PTSD symptoms were characterized by avoidance behavior, intrusive and distressing recollections, and anger. There were no significant differences in depression or paranoid state between the two groups, but former comfort women had impairments in anger control. Former comfort women with PTSD were more depressed. On the Rorschach test, former comfort women revealed characteristic responses related not only to sex and morbidity but also to anger and violence. The small number of subjects might not represent all former comfort women. Some data collected by self report might limit the objectivity of the results. The results suggest that former comfort women are still suffering from traumatic memories, symptoms of PTSD, including avoidant behavior, and anger control impairment, even 60 years after the end of the war.

The Potato Chip Really Does Look Like Elvis! Neural Hallmarks of Conceptual Processing Associated with Finding Novel Shapes Subjectively Meaningful

2012-01-01

Clouds and inkblots often compellingly resemble something else—faces, animals, or other identifiable objects. Here, we investigated illusions of meaning produced by novel visual shapes. Individuals found some shapes meaningful and others meaningless, with considerable variability among individuals in these subjective categorizations. Repetition for shapes endorsed as meaningful produced conceptual priming in a priming test along with concurrent activity reductions in cortical regions associated with conceptual processing of real objects. Subjectively meaningless shapes elicited robust activity in the same brain areas, but activity was not influenced by repetition. Thus, all shapes were conceptually evaluated, but stable conceptual representations supported neural priming for meaningful shapes only. During a recognition memory test, performance was associated with increased frontoparietal activity, regardless of meaningfulness. In contrast, neural conceptual priming effects for meaningful shapes occurred during both priming and recognition testing. These different patterns of brain activation as a function of stimulus repetition, type of memory test, and subjective meaningfulness underscore the distinctive neural bases of conceptual fluency versus episodic memory retrieval. Finding meaning in ambiguous stimuli appears to depend on conceptual evaluation and cortical processing events similar to those typically observed for known objects. To the brain, the vaguely Elvis-like potato chip truly can provide a substitute for the King himself. PMID:22079921

The role of the right hemisphere in form perception and visual gnosis organization.

PubMed

Belyi, B I

1988-06-01

Peculiarities of series of picture interpretations and Rorschach test results in patients with unilateral benign hemispheric tumours are discussed. It is concluded that visual perception in the right hemisphere has hierarchic structure, i.e., each successive area from the occipital lobe towards the frontal having a more complicated function. Visual engrams are distributed over the right hemisphere in a manner similar to the way the visual information is recorded in holographic systems. In any impairment of the right hemisphere a tendency towards whole but unclear vision arises. The preservation of lower levels of visual perception provides for clear vision only of small parts of the image. Thus, confabulatory phenomena arises, which are specific for right hemispheric lesions.

Who has nightmares? The personality of the lifelong nightmare sufferer.

1987-01-01

Twelve lifelong nightmare sufferers, 12 vivid dreamers who had no nightmares, and 12 persons who had neither nightmares nor vivid dreams were studied in a series of structured interviews, psychological tests, and other tests. The group with nightmares had significantly higher scores on the "psychotic" side of the Minnesota Multiphasic Personality Inventory profile than the other two groups, scored higher on a "boundary deficit" score of the Rorschach test, and had more first- and second-degree relatives with nightmares, psychological problems, and psychiatric hospitalization. There were no significant differences between the groups with vivid and nonvivid dreams. On interview, the frequent nightmare sufferers were a group of sensitive, open persons who had features of the "schizophrenic spectrum disorders," but who also had artistic and creative tendencies and interests, in contrast to the other groups. These results confirm and extend our previous findings in a group of 38 frequent nightmare sufferers.

This presentation will review the life and contributions of Dr. Edgar Parker, the infamous and controversial pioneer who specialized in a precarious straddling of the ethics of the commercial marketplace and the ethics of care. Something of a Rorschach test, he was alternatively referred to as a charlatan, the first people's dentist, a renegade, a crusader, a quack, the Henry Ford of dentistry, and "a menace to the dignity of the profession". He eventually owned and managed thirty dental offices, several in San Francisco, as well as the Parker Dental Circus. Because many young, twenty-first century practitioners have little problem with slick advertising, it seems appropriate to revisit Painless Parker's career and contribution to the current state of affairs.

Identifying dissociative identity disorder: a self-report and projective study.

Scroppo, J C; Drob, S L; Weinberger, J L; Eagle, P

1998-05-01

This study compared 21 female adult psychiatric patients diagnosed with dissociative identity disorder (DID) with 21 female adult nondissociative psychiatric patients to determine whether DID patients exhibit a distinguishing set of clinical features, and perceptual, attentional, and cognitive processes. Participants were assessed with the Dissociative Disorders Interview Schedule to assess diagnostic status. Group scores on the Dissociative Experiences Scale, Tellegen Absorption Scale, Childhood Trauma Questionnaire, Brief Symptom Inventory, and the Rorschach test were compared. DID participants reported earlier and more severe childhood trauma, more dissociative symptoms, and a greater propensity for altered states of consciousness. The DID participants also exhibited increased projective and imaginative activity, a diminished ability to integrate mental contents, a complex and driven cognitive style, and a highly unconventional view of reality.

The nonlinear, complex sequential organization of behavior in schizophrenic patients: neurocognitive strategies and clinical correlations.

PubMed

Paulus, M P; Perry, W; Braff, D L

1999-09-01

Thought disorder is a hallmark of schizophrenia and can be inferred from disorganized behavior. Measures of the sequential organization of behavior are important because they reflect the cognitive processes of the selection and sequencing of behavioral elements, which generate observable and analyzable behavioral patterns. In this context, sequences of choices generated by schizophrenic patients in a two-choice guessing task fluctuate significantly, which reflects an "oscillating dysregulation" between highly predictable and highly unpredictable subsequences within a single test session. In this study, we aimed to clarify the significance of dysregulation by seeing whether demographic, clinical, neuropsychological, and psychological measures predict the degree of dysregulation observed on this two-choice task. Thirty schizophrenic patients repeatedly performed a LEFT or RIGHT key press that was followed by a stimulus, which occurred randomly on the left or right side of the computer screen. Thus, the stimulus location had nothing to do with the key press behavior. The range of key press sequence predictabilities as measured by the dynamical entropy was used to quantify the dysregulation of response sequences and reflects the range of fixity and randomness of the responses. A factor analysis was performed and step-wise multiple regression analyses were used to relate the factor scores to demographic, clinical, symptomatic, Wisconsin Card Sorting Test (WCST), and Rorschach variables. The LEFT/RIGHT key press sequences were determined by three factors: 1) the degree of win-stay/lose-shift strategy; 2) the degree of contextual influence on the current choice; and 3) the degree of dysregulation on the choice task. Demographic and clinical variables did not predict any of the three response patterns on the choice task. In contrast, the WCST and Rorschach test predicted performance on various factors of choice task response patterns. Schizophrenic patients employ several

Background One of the clinically relevant problems of Internet use is the phenomenon of Internet addiction. Considering the fact that there is ample evidence for the relationship between attachment style and substance abuse, it stands to reason that attachment theory can also make an important contribution to the understanding of the pathogenesis of Internet addiction. Objective The aim of this study was to examine people’s tendency toward pathological Internet usage in relation to their attachment style. Methods An online survey was conducted. Sociodemographic data, attachment style (Bielefeld questionnaire partnership expectations), symptoms of Internet addiction (scale for online addiction for adults), used Web-based services, and online relationship motives (Cyber Relationship Motive Scale, CRMS-D) were assessed. In order to confirm the findings, a study using the Rorschach test was also conducted. Results In total, 245 subjects were recruited. Participants with insecure attachment style showed a higher tendency to pathological Internet usage compared with securely attached participants. An ambivalent attachment style was particularly associated with pathological Internet usage. Escapist and social-compensatory motives played an important role for insecurely attached subjects. However, there were no significant effects with respect to Web-based services and apps used. Results of the analysis of the Rorschach protocol with 16 subjects corroborated these results. Users with pathological Internet use frequently showed signs of infantile relationship structures in the context of social groups. This refers to the results of the Web-based survey, in which interpersonal relationships were the result of an insecure attachment style. Conclusions Pathological Internet use was a function of insecure attachment and limited interpersonal relationships. PMID:28526662

Munczek, D S; Tuber, S

1998-12-01

This paper, based on an exploratory study in Honduras, examines the psychological effects of political disappearance and assassination on surviving child family members. There are few, if any, comparative field studies of non-immigrant, non-refugee or non-clinical populations of children with forcibly disappeared and assassinated parents. In Latin America, violent state power has been exercised in a number of ways, including physical intimidation, jailing, murder and "disappearance". This research compares 16 Honduran children who have experienced the loss of a parent through forced disappearance with 11 Honduran children who suffered a similar loss from a political assassination. Surviving parents or caretakers of these children were also interviewed. Differences between children of the disappeared and assassinated were analyzed using a Rorschach object relations scale, post-traumatic stress and symptom and behavior scales and interviews with the children and the surviving parents. Both groups of children have symptoms of traumatic stress, depression, anxiety and aggressive feelings. Children of both groups remain symptomatic for many years after their loss and children with disappeared parents present more unconscious emotional disturbance in the Rorschach object relations scale than children with assassinated parents. The lack of physical, emotional and legal resolution in forced disappearance appears to impede mourning and a return to age-appropriate concerns.

A study was carried out under the aegis of Indian Council of Medical Research, New Delhi with objectives to identify psychosocial, physical, psychiatric, anthropometric and psychometric risk factors in recidivistic criminals, which could predict a future recidivistic criminal. The paper presents study observations on 250 experimental, 250 control-1 and 250 control-2 subjects. Experimental and control-1 subjects were recruited from district jails of Uttar Pradesh and control-2 from the community. Pretested Semi-structured proformae, Verghese and Beig Symptoms Checklist, International Personality Disorder Examination module, Hostility and Direction of Hostility Questionnaire, Rorschach Ink Blot Test and Standard Anthropometric instruments were used to collect data on study probands. All the three groups were compared using Analysis of Variance and Chi-Square Test. The results highlight a number of psycho-social, psychiatric, psychometric and anthropometric factors which were found to have significant association with recidivistic criminal behaviour. The findings would not only help in identifying future recidivistic criminals but can also be used for legal, judicial, interventional and corrective purposes. PMID:21408043

Sexual abuse, family environment, and psychological symptoms: on the validity of statistical control.

PubMed

Briere, J; Elliott, D M

1993-04-01

M. R. Nash, T. L. Hulsey, M. C. Sexton, T. L. Harralson, and W. Lambert (1993) reported on the effects of controlling for family environment when studying sexual abuse sequelae. Sexual abuse history was associated with elevated Minnesota Multiphasic Personality Inventory and Rorschach scores in a sample of 105 women, but many of the reported differences disappeared when a Family Functioning Scale score was used as a covariate. The present article considers the findings of Nash et al. in terms of the theoretical and statistical constraints placed on analysis of covariance and other partializing procedures. Because family dysfunction is not always causally antecedent to sexual abuse, and given the quasi-experimental quality of most abuse research, the use of covariate techniques to test hypotheses about the causal role of family environment in the impacts of sexual abuse may be ill advised. Analyses of a 2,964-subject data set illustrate these concerns.

Personality, especially emotional reactions of two solvent exposed groups and a nonexposed reference group were described by means of 20 formal, content and check-list type of Rorschach variables. Another objective of the study was to explore the suitability and psychological meaning of other types of Rorschach variables than those applied earlier in the field of behavioral toxicology. The factor analyses grouped the applied variables into factors of Productivity, Ego Strength, Control of Emotionality, Defensive Introversion and Aggressiveness. One solvent group, a patient groups (N.53), was characterized by a high number of Organic signs and a low Genetic Level, indicating possiblemore » psychoorganic deterioration. The other solvent group, styrene exposed but subjectively healthy (N.98), was characterized by few emotional reactions, low Anxiety and a low number of Neurotic Signs. the long duration of exposure of the solvent patient group (mean 10.2 +/- 8.7 years) was related to variables of the Productivity factor, a finding that indicates a possible better adjustment of those exposed for a longer time. The duration of exposure of the styrene exposed group (mean 4.9 +/- 3.2 years) revealed a very slight relation to personality variables, but the mean urinary mandelic acid concentration, indicating the level of styrene exposure, correlated with increased emotional reactions. For the most part definite causal conclusions could not be drawn because of the cross-sectional design of the study.« less

Psychological Assessment Training in Clinical Psychology Doctoral Programs.

PubMed

Mihura, Joni L; Roy, Manali; Graceffo, Robert A

2017-01-01

We surveyed American Psychological Association-accredited clinical psychology doctoral programs' (n = 83) training in psychological assessment-specifically, their coverage of various assessment topics and tests in courses and practica, and whether the training was optional or required. We report results overall and separately per training model (clinical science, scientist-practitioner, and practitioner-focused). Overall, our results suggest that psychological assessment training is as active, or even more active, than in previous years. Areas of increased emphasis include clinical interviewing and psychometrics; multimethod, outcomes, health, and collaborative or therapeutic assessment; and different types of cognitive and self-report personality tests. All or almost all practice-focused programs offered training with the Thematic Apperception Test and Rorschach compared to about half of the scientist-practitioner programs and a third of the clinical science programs. Although almost all programs reported teaching multimethod assessment, what constitutes different methods of assessing psychopathology should be clarified in future studies because many programs appear to rely on one method-self-report (especially clinical science programs). Although doctoral programs covered many assessment topics and tests in didactic courses, there appears to be a shortage of program-run opportunities for students to obtain applied assessment training. Finally, we encourage doctoral programs to be familiar with (a) internships' assessment expectations and opportunities, (b) the professional guidelines for assessment training, and (c) the American Psychological Association's requirements for preinternship assessment competencies.

Blunted vocal affect and expression is not associated with schizophrenia: A computerized acoustic analysis of speech under ambiguous conditions.

PubMed

Meaux, Lauren T; Mitchell, Kyle R; Cohen, Alex S

2018-05-01

Patients with schizophrenia are consistently rated by clinicians as having high levels of blunted vocal affect and alogia. However, objective technologies have often failed to substantiate these abnormalities. It could be the case that negative symptoms are context-dependent. The present study examined speech elicited under conditions demonstrated to exacerbate thought disorder. The Rorschach Test was administered to 36 outpatients with schizophrenia and 25 nonpatient controls. Replies to separate "perceptual" and "memory" phases were analyzed using validated acoustic analytic methods. Compared to nonpatient controls, schizophrenia patients did not display abnormal speech expression on objective measure of blunted vocal affect or alogia. Moreover, clinical ratings of negative symptoms were not significantly correlated with objective measures. These findings suggest that in patients with schizophrenia, vocal affect/alogia is generally unremarkable under ambiguous conditions. Clarifying the nature of blunted vocal affect and alogia, and how objective measures correspond to what clinicians attend to when making clinical ratings are important directions for future research.

The cognitive, behavioral, and personality profiles of a male monozygotic triplet set discordant for sexual orientation.

PubMed

Hershberger, Scott L; Segal, Nancy L

2004-10-01

The neurohormonal theory of sexual orientation proposes that homosexual men and homosexual women are exposed prenatally to a hormonal environment that is similar to that of the other sex. Prenatal exposure to an opposite-sex hormonal environment may lead the nervous system to develop in a manner consistent with the opposite sex. If this cross-sex exposure occurs, one prediction would be that the cognitive ability profile of homosexual men would be similar to that of heterosexual women. This study examined a set of male monozygotic triplets, aged 21 years, discordant for sexual orientation: 2 of the triplets were heterosexual, 1 was homosexual. The triplets were administered measures of 23 domains of cognitive ability, as well as measures of sexual orientation and masculinity/femininity. On the measures of cognitive ability, the triplets performed similarly, yet consistent differences were found between the 2 heterosexual triplets and the 1 homosexual cotriplet. Differences having the same pattern were found for the number of Schafer homosexuality signs on the Rorschach, and on a homosexuality scale derived from items on the Minnesota Multiphasic Personality Inventory--2 (MMPI-2). Responses from the homosexual triplet were in a more feminine direction than responses from his 2 heterosexual cotriplets on measures of masculinity-femininity, which included measures derived from Rorschach responses, the MMPI-2 Masculinity-Femininity scale, the Bem Sex Role Inventory, and the Boyhood Gender Conformity Scale. Responses to the 16 Personality Factor Questionnaire also distinguished the 1 homosexual triplet from the 2 heterosexual cotriplets. These findings support the view that the prenatal hormonal environment may have enduring effects on selected behavioral traits. Copyright 2004 Springer Science + Business Media, Inc.

Assessment of self-perception of transsexual persons: pilot study of 15 patients.

There have been few studies in the area of Self-Perception in transsexual persons, except for the population of transsexual adolescents. Bearing in mind its importance not only in the assessment of personality but also in predicting adaptive capacity, the goal of our research is based on the examination of Self-Perception of adult transsexual persons. The study was conducted using a Rorschach test, which provides an insight into various aspects of Self-Perception. The sample consisted of 15 transsexual persons, who passed the standard diagnostic procedure. The results suggest that transsexual persons manage to maintain Adequate Self-Esteem. Hypervigilance Index and Obsessive Style Index are negative, while the values showing a negative quality of Self-Regard and the capacity for introspection tend to increase. In the process of Self-Introspection, negative and painful emotional states are often perceived. The estimation of Self-Perception in adult transsexual persons indicates a trend of subjective perception of a personal imperfection or inadequacy. This is probably the result of experiencing discomfort for a number of years due to gender incongruence and dysphoria, in particular in persons who enter the sex reassignment procedure later in their adulthood.

Numerous studies have explored how patients and their caregivers cope with amyotrophic lateral sclerosis (ALS), but the literature completely lacks research on the psychological impact of the disease on patients' children. The aim of our study was to investigate the emotional and psychological impact of a parent with ALS on school-age children and adolescents in terms of problem behavior, adjustment, and personality characteristics. The study involved 23 children (mean age = 10.62 years, six females) with a parent suffering from ALS, and both their parents. Children were matched for age, gender, and birth-order with a control group of children with healthy parents. They were administered the Youth Self Report (YSR) questionnaire and the Rorschach Comprehensive System, and their healthy parent completed the Child Behavior Checklist (CBCL). Findings clearly showed that, compared with controls, children with a parent who had ALS had several clinically significant adverse emotional and behavioral consequences, with emotional and behavioral problems, internalizing problems, anxiety and depressive symptoms. Children of a parent with ALS scored higher than controls for the Total Problems, Internalizing Problems, Anxious/Depressed and Withdrawn/Depressed scales in the YSR. A relevant percentage of children fell within the clinical range (42.9%) and borderline range (28.6%) for Internalizing Problems. The Rorschach CS confirmed the substantial impact of ALS in a parent on their offspring in terms of internalizing behavior and depression, with adjustment difficulties, psychological pain, and thought problems. Our findings indicate that school-aged children and adolescents with a parent who has ALS are vulnerable and carry a substantially higher risk of internalizing behavior, depressive symptoms, and reactive problems than children with healthy parents. Families affected may need support to cope with such an overwhelming disease.

Attachment patterns and personality dimensions have always been considered important to the development and adaptation of the individual. The first aim of this article was to address some basic questions about the place of attachment in a multimethod assessment when compiling a complete picture of the patient's personality functioning. The second aim was to present the Adult Attachment Projective Picture System (AAP; George & West, 2001) as a valid and productive assessment measure. Based on a single case study of an anorexic young woman, the article demonstrates how the AAP is integrated with the Rorschach Comprehensive System (Exner, 1991, 1993) and other assessment tools in both the assessment and in developing a treatment plan.

Changes in implicit and explicit measures of ego functions and distress among two eating disorder subgroups: outcomes of integrative treatment.

The study examined changes in ego functions and mental distress among eating disorder (ED) adolescent inpatients following integrative treatment. Participants included 31 restricting anorexia nervosa and 25 bingeing/purging spectrum ED inpatients. Rorschach Comprehensive System (CS; Exner, 2003) and self-report measures were administered on admission and discharge. We found that improvement in ego functions, mental distress and ED symptomatology occurred in both ED groups at discharge. Nevertheless, the two ED subgroups exhibited different configurations of change as well as varying patterns of relations between changes in mental distress and ego functions and improvement in ED symptoms. These data further indicate that the restricting and bingeing/purging patients may require different treatment approaches.

In this study, we investigated evidence for reliability and validity of the Perceptual Thinking Index (PTI; Exner, 2000a, 2000b) among an adult inpatient population. We conducted reliability and validity analyses on 107 patients who met the Diagnostic and Statistical Manual of Mental Disorders (4th ed., text revision; American Psychiatric Association, 2000) criteria for a schizophrenia-spectrum disorder (SSD) or mood disorder with no psychotic features (MD). Results provided support for interrater reliability as well as internal consistency of the PTI. Furthermore, the PTI was an effective index in differentiating SSD patients from patients diagnosed with an MD. Finally, the PTI demonstrated adequate diagnostic statistics that can be useful in the classification of patients diagnosed with SSD and MD. We discuss methodological issues, implications for assessment practice, and directions for future research.

The expert and the foreigner: Reflections of forensic transcultural psychopathology on a total of 86 reports by experts on criminal liability.

PubMed

Merzagora, Isabella; Amadasi, Alberto; Blandino, Alberto; Travaini, Guido

In recent times Italy has been experiencing massive migration flows, therefore the attention on the issue of crimes committed by foreigners is increasing. But within trials, in the evaluation of criminal liability of foreigners, how do experts deal with them? Do the performed evaluations take cultural diversity into account? The present study took origin from these questions and examined a total of 86 reports by experts on criminal liability of foreign persons (16 females and 70 males). Examinees have been declared indictable in 31 cases (36%), totally mentally ill in 40 cases (45%) and with diminished liability in 15 cases (17%); when liability was excluded, examinees were diagnosed in 11 cases with mood disorders, in 23 cases with personality disorders, in 4 cases with adaptation disorders and post-traumatic stress disorder and in 10 cases with different diagnoses (in some cases more than one diagnosis was present). None of the reports used the section of the DSM concerning "cultural framing". Tests were used in 48 surveys (56% of cases), with more tests for each examinee, for a total of 39 Rorschach, 14 Raven test, 8 Minnesota Multiphasic Personality Inventory - MMPI - 4 Wechsler Adult Intelligence Scale - WAIS - level test, 8 Thematic Apperception test. When subjects were diagnosed with mental disorder and with diminished liability, 42 (79%) were also socially dangerous. Results highlight the importance of the relationship between the expert and the foreigner. Many factors ought to be critically considered by experts dealing with foreigners, like cultural awareness, knowledge of verbal communication, critical consideration of meanings and diagnosis, knowledge of the foreigners' personal story, presence of tests with inexact information and cultural fallacy.

A meta-analysis of an implicit measure of personality functioning: the Mutuality of Autonomy Scale.

PubMed

Graceffo, Robert A; Mihura, Joni L; Meyer, Gregory J

2014-01-01

The Mutuality of Autonomy scale (MA) is a Rorschach variable designed to capture the degree to which individuals mentally represent self and other as mutually autonomous versus pathologically destructive (Urist, 1977). Discussions of the MA's validity found in articles and chapters usually claim good support, which we evaluated by a systematic review and meta-analysis of its construct validity. Overall, in a random effects analysis across 24 samples (N = 1,801) and 91 effect sizes, the MA scale was found to maintain a relationship of r =.20, 95% CI [.16,.25], with relevant validity criteria. We hypothesized that MA summary scores that aggregate more MA response-level data would maintain the strongest relationship with relevant validity criteria. Results supported this hypothesis (aggregated scoring method: r =.24, k = 57, S = 24; nonaggregated scoring methods: r =.15, k = 34, S = 10; p =.039, 2-tailed). Across 7 exploratory moderator analyses, only 1 (criterion method) produced significant results. Criteria derived from the Thematic Apperception Test produced smaller effects than clinician ratings, diagnostic differentiation, and self-attributed characteristics; criteria derived from observer reports produced smaller effects than clinician ratings and self-attributed characteristics. Implications of the study's findings are discussed in terms of both research and clinical work.

This study was designed to study patients with intolerance to pesticide smells. Ten subjects chosen were complaining of vague symptoms such as headache, dizziness, fatigue, nausea, vomiting, abdominal pain, myalgia, flu-like symptoms, etc., whenever exposed to the pesticide smells even at low intensity. To determine whether the etiology of this kind of pesticide hypersensitivity was of organic or psychiatric nature, all the subjects underwent tests as follows: complete blood cell count, urinalysis, and blood chemistry as routine tests; esophogastroduodenoscopy and abdomen ultrasonography for the gastrointestinal symptoms; chest x-ray, pulmonary function tests, and electrocardiography for the respiratory and/or cardiac symptoms; nerve conduction velocity and brain magnetic resonance imaging (MRI) for peripheral and central nerve system symptoms; and K-WAIS, Rey-Kim memory test, Rorschach, Mini Mental State Examination (MMSE), and Minnesota Multiphasic Personality Inventory (MMPI) for psychoanalysis. Of the 10 cases in which the chief complaint was headache, symptoms of two cases were caused by maxillary sinusitis. Another two showed typical multiple chemical sensitivity (MCS) or idiopathic environmental intolerance (IEI). Six out of the 10 cases, whose symptoms closely resembled the others, did not conclusively meet the criteria of classic MCS or IEI. The subjects of this case shared vague fears, both fear of pesticides and hypochondriasis. Some subjects faced financial insecurity and social uncertainty; others felt uneasy about the future of their farming life. Thus, to help verify the causes of MCS or IEI, which is strongly suggestive of pesticide smells, diagnosis needs a dual approach: on the anima and soma. Psychoanalysis can delve into the mental status of the patients to see whether the patients are aware of their symptoms. Clinical tests can see through the physical structure and functions of the organs on which patients' complaints are centered.

2012-01-01

Evidence has started to accumulate that relates pedophilia to a history of being a victim of sexual abuse as well as to comorbidity with organic vulnerabilities. During a naturalistic study regarding treatment of pedophilia, the authors had access to clinical and psychodiagnostic evaluations of Israeli Jewish ultraorthodox male pedophiles outside the forensic system. Using psychiatric examination as well as a battery of psychological tests, presence of history of trauma as well as comorbidity with organic vulnerabilities among this unique sub-group was examined. This survey was part of a larger scale research on the effectiveness of Decapeptyl injections as treatment for pedophilia. All participants in the original research underwent comprehensive psychological assessment including an extensive clinical interview as well as psychological tests (Bender, Rorschach and TAT). Of the patients participating in the research, this survey focused on the group of 46 ultra-orthodox male pedophiles. Cross-tabs analyses were conducted in order to examine prevalence of history of trauma and organic vulnerabilities in this specific group. Based on self reports combined with corroborating reports (obtained from parents, educators and medical staff), together with indications in psychological tests, we found that 82.6% of participants were victims of sexual trauma as children and 87% suffer from some kind of organic vulnerability (learning disabilities, disinhibitions, etc.). LIMITATIONS of this small convenience sample that influence ability to generalize are discussed. The current survey indicates that in this sample, the ultra-orthodox male pedophile was frequently a victim of childhood sexual trauma, and exhibited indications of organic vulnerabilities. This is more pronounced than findings in previous studies, and calls for further research in order to understand the underlying causes.

This paper is an outline of a wide program that is currently under development in the large territory of Argentina. The Director of the Program is Dr. Fernando Pagés Larraya; it is supported by the National Council of Scientific Researches (CONICET) and the National Board of Mental Health. The general purpose of the program is to study the prevalence of mental disorders in different ethnographic areas within the country. Epidemiology allows the forecasting of disease occurence. A research work this area may be qualified "effective" if it provides useful data for prevention programs. Therefore, it is necessary that researches and professional responsibles of Mental Health Governmental decissions work together. This rapprochment is being attempted in developing the Argentine research program. It has a cross-cultural approach. It can be called "a way of thinking" as opposed to a precise methodology. A considerable variety of research tools are being used, depending on the specific purposes and the characteristics of the ethnographic areas. One of the main difficulties in choosing a technique for "case-finding" is uncertainty about where to place the "cut-off point" between presence and absence of illness. In this program the Present State Examination (PSE) is used in population surveys of large urban centers. It is a semi-structured interview that has been extensively tested. In small rural communities, the work is done using "key-informants" and applying the snow-ball sample technique. One specific purpose of the research is the study of the modal personality structure in each ethnographic area, formulated in terms of the Holtzman Inkblot Test. The paper shows the relationships between purposes, research tools and responsible professionals. There is hardly time or surplus intellectual energy for polemic and alienation between clinicians and social scientists. Theories, methodologies, research data and prevention programs have not developed harmoniously. We need to

Nocturnal enuresis in a longitudinal perspective. A primary problem of maturity and/or a secondary environmental reaction?

PubMed

Klackenberg, G

1981-07-01

The study is part of a prospective longitudinal investigation, involving annual somatic, psychological and social check-ups in a random sample of 212 children. Data are presented on the gradual achievement of bladder control, with relapses into wetting. Information is provided on relationships with training, with behavioural variables, with emotional maturity (Rorschach) and with sleep. It seems probable that primary enuresis usually ceases by the age of 8 at the latest and that enuresis in older children is a secondary emotional disorder which may, however, have started at an earlier age. The 6-year-old enuretic shows signs of delayed emotional maturity. The relation with somnambulism is ambiguous. Enuresis is not significantly related to training. None of the data obtained in this study conflict with the theory that primary enuresis is chiefly a maturity problem, the nature of which can be emotional. The neurophysiological aspect has not been investigated.

Do pedophiles have a weaker identity structure compared with nonsexual offenders?

Tardi, M; Van Gijseghem, H

2001-10-01

The aim of this study was to determine whether pedophiles have a weaker identity structure compared with nonsexual offenders. The recruitment process secured the participation of 87 male adult subjects, divided into three groups: 27 pedophiles who abused male victims (X = 38.6 years), 30 pedophiles who abused female victims (X = 35.5 years), 30 nonsexual offenders (X = 29.8 years). The concept of identity was examined on the basis of two factors: body image limits and ego identity. Two objective tests, the Minnesota Multiphasic Personality Inventory (MMPI) and the Ego Identity Scale, and one projective test, the Rorschach scored according to the Fisher and Cleveland method, were used. A multivariate analysis of covariance, at a significance threshold of p < .05, indicated that pedophiles who abused female victims and pedophiles who abused male victims have more fragile body image limits, as measured by the penetration score, and present a higher level of social introversion (Si scale) than do nonsexual offenders. Moreover, pedophiles who abused male victims have a weaker ego (Es scale) than do pedophiles who abused female victims and nonsexual offenders. In other respects, no significant intergroup difference emerged in terms of body image limits as measured by the barrier score and of strength of ego identity (Ego Identity Scale). Conceptual and empirical elements related to body image and ego identity are addressed to shed light on the potential disturbances in the identity of pedophile subjects. These results imply not only that certain impairments exist at the level of the basis structures of the personality, but also that these impairments should be taken into account in formulating a program and devising a therapeutic process for pedophiles.

To report concomitant macular hole and central serous chorioretinopathy after blunt trauma. Case presentation. A 31-year-old man presented with a complaint of a reduction in visual acuity and blurred vision in the right eye after blunt eye trauma. The patient did not have a history of any systemic disorders and drug administration. On ocular examination, best corrected visual acuity was 2/20 in the right eye and 20/20 in the left eye. His intraocular pressures were 14 mmHg right eye and 13 mmHg left eye by applanation tonometry. Dilated fundus examination of the right eye showed macular hole and serous macular detachment, whereas the left eye was completely normal. Optical coherence tomography confirmed the full-thickness macular hole and subretinal fluid in the right eye, and ink-blot leakage pattern was determined in fundus fluorescein angiography. The patient was followed up without systemic therapy. Three months later, the vision was 10/20 in the right eye with completely closed macular hole and complete resolution of subretinal fluid. This is the first case which describes concomitant macular hole and central serous chorioretinopathy after blunt eye trauma. This presentation demonstrates that macular hole and central serous chorioretinopathy can be developed after blunt trauma. Both pathology may result with spontaneous closure of macular hole and spontaneous resolution of subretinal fluid within 3 months.

Transient Pressure Test Article Test Program

NASA Technical Reports Server (NTRS)

Vibbart, Charles M.

1989-01-01

The Transient Pressure Test Article (TPTA) test program is being conducted at a new test facility located in the East Test Area at the National Aeronautics and Space Administration's (NASA's) Marshall Space Flight Center (MSFC) in Huntsville, Alabama. This facility, along with the special test equipment (STE) required for facility support, was constructed specifically to test and verify the sealing capability of the Redesigned Solid Rocket Motor (RSRM) field, igniter, and nozzle joints. The test article consists of full scale RSRM hardware loaded with inert propellant and assembled in a short stack configuration. The TPTA is pressurized by igniting a propellant cartridge capable of inducing a pressure rise rate which stimulates the ignition transient that occurs during launch. Dynamic loads are applied during the pressure cycle to simulate external tank attach (ETA) strut loads present on the ETA ring. Sealing ability of the redesigned joints is evaluated under joint movement conditions produced by these combined loads since joint sealing ability depends on seal resilience velocity being greater than gap opening velocity. Also, maximum flight dynamic loads are applied to the test article which is either pressurized to 600 psia using gaseous nitrogen (GN2) or applied to the test article as the pressure decays inside the test article on the down cycle after the ignition transient cycle. This new test facility is examined with respect to its capabilities. In addition, both the topic of test effectiveness versus space vehicle flight performance and new aerospace test techniques, as well as a comparison between the old SRM design and the RSRM are presented.

Prevention of traffic accidents: the assessment of perceptual-motor alterations before obtaining a driving license. A longitudinal study of the first years of driving.

PubMed

Martín, Fermina Sánchez; Estévez, M Angeles Quiroga

2005-03-01

A longitudinal study was designed with two objectives: first, to provide a wide cognitive, personality and social description of new drivers before they started to drive cars. Second, to examine the relationship between cognitive and other characteristics drivers had before obtaining their driving license and the number and type of accidents they were involved in during the first years as drivers. The longitudinal study started in 1997 and ended in 2002. The first assessment was made up of 241 individuals at the time they enrolled on the driving course. The follow-up evaluation in the year 2002 was carried out on 144 components of the initial sample after five years driving. Age, gender and education level were matched to represent the population of Spain. Participants were assessed with the Bender Test for visual-motor ability, the B101 Test for practical intelligence, the B19 Test for visual-motor bi-manual coordination, and the TKK-1108 for speed anticipation. Personality was also evaluated with the Rorschach test and the PSY (Psychological Assessment Questionnaire). Five years later, a new examination of all those variables was made as well as a structured interview with each participant in order to collect data relating to significant life events during that time, driving habits, opinions in relation to certain traffic rules and information on accidents, incidents and/or sanctions. Serious and/or minor accidents are concentrated on a few drivers. Accidentality is not related to gender or age, but educational level is related to serious accidents. The number of accidents (severe or minor ones) cannot be predicted if considered as a continuous variable, but it is possible if considered as a discrete variable. In this case two different cognitive profiles account for the number and type of accidents. The number and type of accidents during their first years of driving are related to the cognitive profiles of drivers assessed before they obtained their driving

Dickinson, D.; Schlemmer, J.; Hicks, F.; Michel, F.; Moog, R. D.

1972-01-01

Balloon Launched Decelerator Test (BLDT) flights were conducted during the summer of 1972 over the White Sands Missile Range. The purpose of these tests was to qualify the Viking disk-gap band parachute system behind a full-scale simulator of the Viking Entry Vehicle over the maximum range of entry conditions anticipated in the Viking '75 soft landing on Mars. Test concerns centered on the ability of a minimum weight parachute system to operate without structural damage in the turbulent wake of the blunt-body entry vehicle (140 deg, 11.5 diameter cone). This is the first known instance of parachute operation at supersonic speeds in the wake of such a large blunt body. The flight tests utilized the largest successful balloon-payload weight combination known to get to high altitude (120kft) where rocket engines were employed to boost the test vehicle to supersonic speeds and dynamic pressures simulating the range of conditions on Mars.

Personality: individual differences and clinical assessment.

PubMed

Butcher, J N; Rouse, S V

1996-01-01

Research in clinical personality assessment continues to be produced at a high rate. The MMPI/MMPI-2 remains the most popular instrument for both clinical application and psychopathology research. Two other clinical personality instruments, the Rorschach and TAT, continue to find a place in research and clinical assessment. Some new instruments have surfaced recently to deal with areas, such as personality disorders, that have been considered inadequately addressed. There is a growing recognition that the Five-Factor Model is too superficial for clinical assessment that requires more refined and broadened patient information. Clinical personality assessment has successfully survived a number of past challenges. The newest challenge stems from the health-care revolution, in which managed-care providers are reluctant to pay for assessment because of shrinking funds. Psychologists need to develop models for incorporating assessment information into the treatment process. The future is likely to see more extensive research and theoretical development in this endeavor.

Fortenberry, J.; Brownlee, G. R.

1974-01-01

The Viking Mars Lander 1975 dynamic test model and orbiter developmental test model were subjected to forced vibration sine tests. Flight acceptance (FA) and type approval (TA) test levels were applied to the spacecraft structure in a longitudinal test configuration using a 133,440-N (30,000-lb) force shaker. Testing in the two lateral axes (X, Y) was performed at lower levels using four 667-N (150-lb) force shakers. Forced vibration qualification (TA) test levels were successfully imposed on the spacecraft at frequencies down to 10 Hz. Measured responses showed the same character as analytical predictions, and correlation was reasonably good. Because of control system test tolerances, orbiter primary structure generally did not reach the design load limits attained in earlier static testing. A post-test examination of critical orbiter structure disclosed no apparent damage to the structure as a result of the test environment.

Meta-analysis of studies assessing the efficacy of projective techniques in discriminating child sexual abuse.

PubMed

West, M M

1998-11-01

This meta-analysis of 12 studies assesses the efficacy of projective techniques to discriminate between sexually abused children and nonsexually abused children. A literature search was conducted to identify published studies that used projective instruments with sexually abused children. Those studies that reported statistics that allowed for an effect size to be calculated, were then included in the meta-analysis. There were 12 studies that fit the criteria. The projectives reviewed include The Rorschach, The Hand Test, The Thematic Apperception Test (TAT), the Kinetic Family Drawings, Human Figure Drawings, Draw Your Favorite Kind of Day, The Rosebush: A Visualization Strategy, and The House-Tree-Person. The results of this analysis gave an over-all effect size of d = .81, which is a large effect. Six studies included only a norm group of nondistressed, nonabused children with the sexual abuse group. The average effect size was d = .87, which is impressive. Six studies did include a clinical group of distressed nonsexually abused subjects and the effect size lowered to d = .76, which is a medium to large effect. This indicates that projective instruments can discriminate distressed children from nondistressed subjects, quite well. In the studies that included a clinical group of distressed children who were not sexually abused, the lower effect size indicates that the instruments were less able to discriminate the type of distress. This meta-analysis gives evidence that projective techniques have the ability to discriminate between children who have been sexually abused and those who were not abused sexually. However, further research that is designed to include clinical groups of distressed children is needed in order to determine how well the projectives can discriminate the type of distress.

Buehrle, Ralph D.; Templeton, Justin D.; Reaves, Mercedes C.; Horta, Lucas G.; Gaspar, James L.; Bartolotta, Paul A.; Parks, Russel A.; Lazor, Daniel R.

2010-01-01

The first test flight of NASA's Ares I crew launch vehicle, called Ares I-X, was launched on October 28, 2009. Ares I-X used a 4-segment reusable solid rocket booster from the Space Shuttle heritage with mass simulators for the 5th segment, upper stage, crew module and launch abort system. Flight test data will provide important information on ascent loads, vehicle control, separation, and first stage reentry dynamics. As part of hardware verification, a series of modal tests were designed to verify the dynamic finite element model (FEM) used in loads assessments and flight control evaluations. Based on flight control system studies, the critical modes were the first three free-free bending mode pairs. Since a test of the free-free vehicle was not practical within project constraints, modal tests for several configurations during vehicle stacking were defined to calibrate the FEM. Test configurations included two partial stacks and the full Ares I-X flight test vehicle on the Mobile Launcher Platform. This report describes the test requirements, constraints, pre-test analysis, test execution and results for the Ares I-X flight test vehicle modal test on the Mobile Launcher Platform. Initial comparisons between pre-test predictions and test data are also presented.

[Self-esteem, self-centeredness and social-emotional adjustment of gifted children and adolescents].

PubMed

Kostogianni, N; Andronikof, A

2009-10-01

There is an ongoing debate of how giftedness affects social-emotional adjustment. Self-esteem may be an indicator of social-emotional adjustment but insufficient in its explanatory capacity, especially high self-esteem which tends to produce opposite responses in regards to adjustment. A distinction between defensive and genuine high self-esteem could account for these results. In order to understand how self-esteem operates on social-emotional adjustment, it should be associated with other measurements relating to self-concern. In the Rorschach comprehensive system (CS), egocentricity index measures self-centeredness, which can be defined as the balance between self-concern and concern for others. High self-concern is associated with a neglect of the others. Operationalized here, as the interaction of high self-esteem and excessive self-concern, defensive high self-esteem should predict maladaptive outcomes. Participants were aged from 9 to 15 years old, with an IQ greater or equal to 130 on the WISC-III. They were attending regular classes and were not in counseling or psychotherapy. Children and adolescents were administrated the Rorschach CS and the Coopersmith self-esteem inventory. Parents completed the child behaviour checklist (CBCL) which assesses general psychopathology. Seventy-eight subjects' data satisfy the conditions of validity of the instruments used. Gifted boys present more behavior and emotional problems than gifted girls in this study. Self-esteem predicts social-emotional adjustment. There is an interaction between self-esteem and self-concern on psychopathology only for high values of self-esteem. Gifted with high self-esteem associated with high self-concern are more vulnerable to maladjustment than high self-esteem associated with low self-concern. Gifted children and adolescents with low self-esteem experience more problems anyhow. These findings reinforce the view that the gifted are a diverse group in terms of social-emotional adjustment

Reliability of the anterior drawer test, the pivot shift test, and the Lachman test.

Kim, S J; Kim, H K

1995-08-01

In 147 patients with arthroscopically proved chronic injuries of the anterior cruciate ligament, the anterior drawer test, the Lachman test, and the pivot shift test were done before operation under general or spinal anesthesia. Results of the anterior drawer test were positive in 79.6% of the patients, in 98.6% patients having the Lachman test, and in 89.8% of patients having the pivot shift test. In 19 cases (12.9%), arthroscopic examination showed reattachment of the proximally torn end of the anterior cruciate ligament to the posterior cruciate ligament. In these cases, results of the anterior drawer test were positive in 13 patients (68.4%), in 17 (89.5%) patients having the Lachman test, and in 12 patients (63.2%) having the pivot shift test. In 15 cases with a false negative pivot shift test, arthroscopy showed blockage of anterior subluxation of the lateral tibial condyle by a partially functioning portion of the anterior cruciate ligament, which was reattached to the posterior cruciate ligament in 7 cases. In 2 cases with a false negative Lachman test, there was firm reattachment of the torn end of the anterior cruciate ligament to the proximal portion of the posterior cruciate ligament combined with a bucket handle tear of the medial meniscus. The Lachman test was most sensitive in diagnosing chronic injuries of the anterior cruciate ligament. The pivot shift test was also sensitive but was influenced by many factors.

Role of test motivation in intelligence testing.

PubMed

Duckworth, Angela Lee; Quinn, Patrick D; Lynam, Donald R; Loeber, Rolf; Stouthamer-Loeber, Magda

Intelligence tests are widely assumed to measure maximal intellectual performance, and predictive associations between intelligence quotient (IQ) scores and later-life outcomes are typically interpreted as unbiased estimates of the effect of intellectual ability on academic, professional, and social life outcomes. The current investigation critically examines these assumptions and finds evidence against both. First, we examined whether motivation is less than maximal on intelligence tests administered in the context of low-stakes research situations. Specifically, we completed a meta-analysis of random-assignment experiments testing the effects of material incentives on intelligence-test performance on a collective 2,008 participants. Incentives increased IQ scores by an average of 0.64 SD, with larger effects for individuals with lower baseline IQ scores. Second, we tested whether individual differences in motivation during IQ testing can spuriously inflate the predictive validity of intelligence for life outcomes. Trained observers rated test motivation among 251 adolescent boys completing intelligence tests using a 15-min "thin-slice" video sample. IQ score predicted life outcomes, including academic performance in adolescence and criminal convictions, employment, and years of education in early adulthood. After adjusting for the influence of test motivation, however, the predictive validity of intelligence for life outcomes was significantly diminished, particularly for nonacademic outcomes. Collectively, our findings suggest that, under low-stakes research conditions, some individuals try harder than others, and, in this context, test motivation can act as a third-variable confound that inflates estimates of the predictive validity of intelligence for life outcomes.

Managing laboratory test ordering through test frequency filtering.

PubMed

Janssens, Pim M W; Wasser, Gerd

2013-06-01

Modern computer systems allow limits to be set on the periods allowed for repetitive testing. We investigated a computerised system for managing potentially overtly frequent laboratory testing, calculating the financial savings obtained. In consultation with hospital physicians, tests were selected for which 'spare periods' (periods during which tests are barred) might be set to control repetitive testing. The tests were selected and spare periods determined based on known analyte variations in health and disease, variety of tissues or cells giving rise to analytes, clinical conditions and rate of change determining analyte levels, frequency with which doctors need information about the analytes and the logistical needs of the clinic. The operation and acceptance of the system was explored with 23 analytes. Frequency filtering was subsequently introduced for 44 tests, each with their own spare periods. The proportion of tests barred was 0.56%, the most frequent of these being for total cholesterol, uric acid and HDL-cholesterol. The financial savings were 0.33% of the costs of all testing, with HbA1c, HDL-cholesterol and vitamin B12 yielding the largest savings. Following the introduction of the system the number of barred tests ultimately decreased, suggesting accommodation by the test requestors. Managing laboratory testing through computerised limits to prevent overtly frequent testing is feasible. The savings were relatively low, but sustaining the system takes little effort, giving little reason not to apply it. The findings will serve as a basis for improving the system and may guide others in introducing similar systems.

Integrated Test and Evaluation Flight Test 3 Flight Test Plan

NASA Technical Reports Server (NTRS)

Marston, Michael Lawrence

2015-01-01

The desire and ability to fly Unmanned Aircraft Systems (UAS) in the National Airspace System (NAS) is of increasing urgency. The application of unmanned aircraft to perform national security, defense, scientific, and emergency management are driving the critical need for less restrictive access by UAS to the NAS. UAS represent a new capability that will provide a variety of services in the government (public) and commercial (civil) aviation sectors. The growth of this potential industry has not yet been realized due to the lack of a common understanding of what is required to safely operate UAS in the NAS. NASA's UAS Integration into the NAS Project is conducting research in the areas of Separation Assurance/Sense and Avoid Interoperability, Human Systems Integration (HSI), and Communication to support reducing the barriers of UAS access to the NAS. This research is broken into two research themes namely, UAS Integration and Test Infrastructure. UAS Integration focuses on airspace integration procedures and performance standards to enable UAS integration in the air transportation system, covering Sense and Avoid (SAA) performance standards, command and control performance standards, and human systems integration. The focus of Test Infrastructure is to enable development and validation of airspace integration procedures and performance standards, including the integrated test and evaluation. In support of the integrated test and evaluation efforts, the Project will develop an adaptable, scalable, and schedulable relevant test environment capable of evaluating concepts and technologies for unmanned aircraft systems to safely operate in the NAS. To accomplish this task, the Project will conduct a series of Human-in-the-Loop and Flight Test activities that integrate key concepts, technologies and/or procedures in a relevant air traffic environment. Each of the integrated events will build on the technical achievements, fidelity and complexity of the previous tests and

Morpheus Vertical Test Bed Flight Testing

Hart, Jeremy; Devolites, Jennifer

2014-01-01

NASA's Morpheus Project has developed and tested a prototype planetary lander capable of vertical takeoff and landing, that is designed to serve as a testbed for advanced spacecraft technologies. The lander vehicle, propelled by a LOX/Methane engine and sized to carry a 500kg payload to the lunar surface, provides a platform for bringing technologies from the laboratory into an integrated flight system at relatively low cost. Morpheus onboard software is autonomous from ignition all the way through landing, and is designed to be capable of executing a variety of flight trajectories, with onboard fault checks and automatic contingency responses. The Morpheus 1.5A vehicle performed 26 integrated vehicle test flights including hot-fire tests, tethered tests, and two attempted freeflights between April 2011 and August 2012. The final flight of Morpheus 1.5A resulted in a loss of the vehicle. In September 2012, development began on the Morpheus 1.5B vehicle, which subsequently followed a similar test campaign culminating in free-flights at a simulated planetary landscape built at Kennedy Space Center's Shuttle Landing Facility. This paper describes the integrated test campaign, including successes and setbacks, and how the system design for handling faults and failures evolved over the course of the project.

Coverage of the Test of Memory Malingering, Victoria Symptom Validity Test, and Word Memory Test on the Internet: is test security threatened?

PubMed

Bauer, Lyndsey; McCaffrey, Robert J

2006-01-01

In forensic neuropsychological settings, maintaining test security has become critically important, especially in regard to symptom validity tests (SVTs). Coaching, which can entail providing patients or litigants with information about the cognitive sequelae of head injury, or teaching them test-taking strategies to avoid detection of symptom dissimulation has been examined experimentally in many research studies. Emerging evidence supports that coaching strategies affect psychological and neuropsychological test performance to differing degrees depending on the coaching paradigm and the tests administered. The present study sought to examine Internet coverage of SVTs because it is potentially another source of coaching, or information that is readily available. Google searches were performed on the Test of Memory Malingering, the Victoria Symptom Validity Test, and the Word Memory Test. Results indicated that there is a variable amount of information available about each test that could threaten test security and validity should inappropriately interested parties find it. Steps that could be taken to improve this situation and limitations to this exploration are discussed.

Multi-axis transient vibration testing of space objects: Test philosophy, test facility, and control strategy

NASA Technical Reports Server (NTRS)

Lachenmayr, Georg

1992-01-01

IABG has been using various servohydraulic test facilities for many years for the reproduction of service loads and environmental loads on all kinds of test objects. For more than 15 years, a multi-axis vibration test facility has been under service, originally designed for earthquake simulation but being upgraded to the demands of space testing. First tests with the DFS/STM showed good reproduction accuracy and demonstrated the feasibility of transient vibration testing of space objects on a multi-axis hydraulic shaker. An approach to structural qualification is possible by using this test philosophy. It will be outlined and its obvious advantages over the state-of-the-art single-axis test will be demonstrated by example results. The new test technique has some special requirements to the test facility exceeding those of earthquake testing. Most important is the high reproduction accuracy demanded for a sophisticated control system. The state-of-the-art approach of analog closed-loop control circuits for each actuator combined with a static decoupling network and an off-line iterative waveform control is not able to meet all the demands. Therefore, the future over-all control system is implemented as hierarchical full digital closed-loop system on a highly parallel transputer network. The innermost layer is the digital actuator controller, the second one is the MDOF-control of the table movement. The outermost layer would be the off-line iterative waveform control, which is dedicated only to deal with the interaction of test table and test object or non-linear effects. The outline of the system will be presented.

Galileo battery testing and the impact of test automation

NASA Technical Reports Server (NTRS)

Pertuch, W. T.; Dils, C. T.

1985-01-01

Test complexity, changes of test specifications, and the demand for tight control of tests led to the development of automated testing used for Galileo and other projects. The use of standardized interfacing, i.e., IEEE-488, with desktop computers and test instruments, resulted in greater reliability, repeatability, and accuracy of both control and data reporting. Increased flexibility of test programming has reduced costs by permitting a wide spectrum of test requirements at one station rather than many stations.

2015-01-01

This document is a flight test report from the Operational perspective for Flight Test Series 3, a subpart of the Unmanned Aircraft System (UAS) Integration in the National Airspace System (NAS) project. Flight Test Series 3 testing began on June 15, 2015, and concluded on August 12, 2015. Participants included NASA Ames Research Center, NASA Armstrong Flight Research Center, NASA Glenn Research Center, NASA Langley Research center, General Atomics Aeronautical Systems, Inc., and Honeywell. Key stakeholders analyzed their System Under Test (SUT) in two distinct configurations. Configuration 1, known as Pairwise Encounters, was subdivided into two parts: 1a, involving a low-speed UAS ownship and intruder(s), and 1b, involving a high-speed surrogate ownship and intruder. Configuration 2, known as Full Mission, involved a surrogate ownship, live intruder(s), and integrated virtual traffic. Table 1 is a summary of flights for each configuration, with data collection flights highlighted in green. Section 2 and 3 of this report give an in-depth description of the flight test period, aircraft involved, flight crew, and mission team. Overall, Flight Test 3 gathered excellent data for each SUT. We attribute this successful outcome in large part from the experience that was acquired from the ACAS Xu SS flight test flown in December 2014. Configuration 1 was a tremendous success, thanks to the training, member participation, integration/testing, and in-depth analysis of the flight points. Although Configuration 2 flights were cancelled after 3 data collection flights due to various problems, the lessons learned from this will help the UAS in the NAS project move forward successfully in future flight phases.

Gender, Thomas K. (Inventor)

2006-01-01

An error response test system and method with increased functionality and improved performance is provided. The error response test system provides the ability to inject errors into the application under test to test the error response of the application under test in an automated and efficient manner. The error response system injects errors into the application through a test mask variable. The test mask variable is added to the application under test. During normal operation, the test mask variable is set to allow the application under test to operate normally. During testing, the error response test system can change the test mask variable to introduce an error into the application under test. The error response system can then monitor the application under test to determine whether the application has the correct response to the error.

Test Stand at the Rocket Engine Test Facility

NASA Image and Video Library

1973-02-21

The thrust stand in the Rocket Engine Test Facility at the National Aeronautics and Space Administration (NASA) Lewis Research Center in Cleveland, Ohio. The Rocket Engine Test Facility was constructed in the mid-1950s to expand upon the smaller test cells built a decade before at the Rocket Laboratory. The $2.5-million Rocket Engine Test Facility could test larger hydrogen-fluorine and hydrogen-oxygen rocket thrust chambers with thrust levels up to 20,000 pounds. Test Stand A, seen in this photograph, was designed to fire vertically mounted rocket engines downward. The exhaust passed through an exhaust gas scrubber and muffler before being vented into the atmosphere. Lewis researchers in the early 1970s used the Rocket Engine Test Facility to perform basic research that could be utilized by designers of the Space Shuttle Main Engines. A new electronic ignition system and timer were installed at the facility for these tests. Lewis researchers demonstrated the benefits of ceramic thermal coatings for the engine’s thrust chamber and determined the optimal composite material for the coatings. They compared the thermal-coated thrust chamber to traditional unlined high-temperature thrust chambers. There were more than 17,000 different configurations tested on this stand between 1973 and 1976. The Rocket Engine Test Facility was later designated a National Historic Landmark for its role in the development of liquid hydrogen as a propellant.

Test Re-Test Reliability of Four Versions of the 3-Cone Test in Non-Athletic Men

PubMed Central

Langley, Jason G.; Chetlin, Robert D.

2017-01-01

Until recently, measurement and evaluation in sport science, especially agility testing, has not always included key elements of proper test construction. Often tests are published without reporting reliability and validity analysis for a specific population. The purpose of the present study was to examine the test re-test reliability of four versions of the 3-Cone Test (3CT), and provide guidance on proper test construction for testing agility in athletic populations. Forty male students enrolled in classes in the Department of Physical Education at a mid-Atlantic university participated. On each of test day participants performed 10 trials. In random order, they performed three trials to the right (3CTR, standard test), three to the left (3CTL), and two modified trials (3CTAR and 3CTAL), which included a reactive component in which a visual cue was given to indicate direction. Intra-class correlation coefficients (ICC) indicated a moderate to high reliability for the four tests, 3CTR 0.79 (0.64-0.88, 95%CI), 3CTL 0.73 (0.55-0.85), 3CTAR 0.85(0.74-0.92), and 3CTAL 0.79 (0.64-0.88). Small standard error of the measurement (SEM) was found; range 0.09 to 0.10. Pearson correlations between tests were high (0.82-0.92) on day one as well as day two (0.72-0.85). These results indicate each version of the 3-Cone Test is reliable; however, further tests are needed with specific athletic populations. Only the 3CTAR and 3CTAL are tests of agility due to the inclusion of a reactive component. Future studies examining agility testing and training should incorporate technological elements, including automated timing systems and motion capture analysis. Such instrumentation will allow for optimal design of tests that simulate sport-specific game conditions. Key points The commonly used 3-cone test (upside down “L” to the right”) is a reliable change of direction speed (CODS) test when evaluating collegiate males.

Deficits in social cognition are common in psychiatric disorders. Validated social cognition measures with good psychometric properties are necessary to assess and target social cognitive deficits. Two recent social cognition tests, the Combined Stories Test (COST) and the Social Knowledge Test (SKT), respectively assess theory of mind and social knowledge. Previous studies have shown good psychometric properties for these tests, but the test-retest reliability has never been documented. The aim of this study was to evaluate the test-retest reliability and the inter-rater reliability of the COST and the SKT. The COST and the SKT were administered twice to a group of forty-two healthy adults, with a delay of approximately four weeks between the assessments. Excellent test-retest reliability was observed for the COST, and a good test-retest reliability was observed for the SKT. There was no evidence of practice effect. Furthermore, an excellent inter-rater reliability was observed for both tests. This study shows a good reliability of the COST and the SKT that adds to the good validity previously reported for these two tests. These good psychometrics properties thus support that the COST and the SKT are adequate measures for the assessment of social cognition. Copyright © 2018. Published by Elsevier B.V.

Test/score/report: Simulation techniques for automating the test process

NASA Technical Reports Server (NTRS)

Hageman, Barbara H.; Sigman, Clayton B.; Koslosky, John T.

1994-01-01

A Test/Score/Report capability is currently being developed for the Transportable Payload Operations Control Center (TPOCC) Advanced Spacecraft Simulator (TASS) system which will automate testing of the Goddard Space Flight Center (GSFC) Payload Operations Control Center (POCC) and Mission Operations Center (MOC) software in three areas: telemetry decommutation, spacecraft command processing, and spacecraft memory load and dump processing. Automated computer control of the acceptance test process is one of the primary goals of a test team. With the proper simulation tools and user interface, the task of acceptance testing, regression testing, and repeatability of specific test procedures of a ground data system can be a simpler task. Ideally, the goal for complete automation would be to plug the operational deliverable into the simulator, press the start button, execute the test procedure, accumulate and analyze the data, score the results, and report the results to the test team along with a go/no recommendation to the test team. In practice, this may not be possible because of inadequate test tools, pressures of schedules, limited resources, etc. Most tests are accomplished using a certain degree of automation and test procedures that are labor intensive. This paper discusses some simulation techniques that can improve the automation of the test process. The TASS system tests the POCC/MOC software and provides a score based on the test results. The TASS system displays statistics on the success of the POCC/MOC system processing in each of the three areas as well as event messages pertaining to the Test/Score/Report processing. The TASS system also provides formatted reports documenting each step performed during the tests and the results of each step. A prototype of the Test/Score/Report capability is available and currently being used to test some POCC/MOC software deliveries. When this capability is fully operational it should greatly reduce the time necessary

Oral Solid Dosage Form Disintegration Testing - The Forgotten Test.

PubMed

Al-Gousous, Jozef; Langguth, Peter

2015-09-01

Since its inception in the 1930s, disintegration testing has become an important quality control (QC) test in pharmaceutical industry, and disintegration test procedures for various dosage forms have been described by the different pharmacopoeias, with harmonization among them still not quite complete. However, because of the fact that complete disintegration does not necessarily imply complete dissolution, much more research has been focused on dissolution rather than on disintegration testing. Nevertheless, owing to its simplicity, disintegration testing seems to be an attractive replacement to dissolution testing as recognized by the International Conference on Harmonization guidelines, in some cases. Therefore, with proper research being carried out to overcome the associated challenges, the full potential of disintegration testing could be tapped saving considerable efforts allocated to QC testing and quality assurance. © 2014 Wiley Periodicals, Inc. and the American Pharmacists Association.

[Knowledge about the relationship through protagonist-director interactions in psychodrama groups].

PubMed

Erdélyi, Ildikó

2005-01-01

This report follows emotional behavior in two psychodrama groups from the "present moment" until "moment of contact" using the Consensus Rorschach method. In the analysis of verbal and nonverbal material of protagonist-director dyads the following patterns were distinguished: a) early relationship patterns; b) affective attunement; c) fit of knowledge about the relationship. The author describes the relationship between the concept of "present moment" in therapy and the role of eye contact. Eye contact produces emotional tension in the context of the "present moment". Moments of contact, however, require implicit and explicit knowledge about the relationship to be constructed simultaneously as well as development of affective interactions. Emotional impulses are stored in implicit memory, which has no immediate availability. However, therapy--including psychodrama--attaches words to behaviors that are beyond the verbal levels as well, and therefore it extends the domain of memory. This is the way in which non-symbolized emotional behavior (including eye contact) and the play's verbal level with symbolic representations of memories are interconnected.

Journeys through the valley of death: multimethod psychological assessment and personality transformation in long-term psychotherapy.

PubMed

Finn, Stephen E

2011-03-01

The Psychodynamic Diagnostic Manual (PDM Task Force, 2006) is based on the assumption that an in-depth understanding of clients' underlying emotional, personality, and interpersonal patterns will facilitate their treatment. In this article I show how such an understanding can be achieved through multimethod psychological assessment, and how useful such information can be in long-term psychotherapy with high-achieving, successful clients who struggle with forming and maintaining intimate relationships. Such treatments are extremely difficult, because when these clients attach to their psychotherapists, many of them temporarily become more symptomatic. I illustrate these points with a detailed account of my long-term therapy with a resilient but highly traumatized young man. Repeated use of the Minnesota Multiphasic Personality Disorder-2 (MMPI-2; Butcher, Dahlstrom, Graham, Tellegen, & Kaemmer, 1989) and Rorschach with my client helped guide us in our work, and also helped create an important therapeutic "opening" into the underlying traumatic material. This and other experiences have convinced me that it is extremely useful for psychologists to have training in both assessment and psychotherapy.

Mastery of the mind East and West: excellence in being and doing and everyday happiness.

PubMed

Brown, Daniel

2009-08-01

Western psychological research on positive psychology and Buddhism have recently converged in their emphasis on the development of positive states, like states of excellence and everyday happiness. Yet, these traditions differ in their approaches to positive states, with respect to a state-trait and doing-being distinction. Western scientific research on peak performance emphasizes discontinuous, time-limited peak performance states wherein individuals do things extraordinarily well in sports and in the arts. The Eastern spiritual traditions emphasize continuous excellence of being, in the form of traits or character strengths. In both traditions mental imagery is a key ingredient to excellence training. With respect to everyday happiness, Western psychological research has focused on the role of meaning systems in the transformation of flow states into vital engagement in everyday life, while Buddhism stresses the role of meditation training to gain mastery over all levels of mind that leads to everyday happiness. Rorschach and tachistoscopic research on advanced meditators suggests that advance meditators have gained unusual mastery over states of mind not yet documented in the Western psychological research on positive psychology.

Diffuser Test

NASA Image and Video Library

2007-09-13

Tests begun at Stennis Space Center's E Complex Sept. 13 evaluated a liquid oxygen lead for engine start performance, part of the A-3 Test Facility Subscale Diffuser Risk Mitigation Project at SSC's E-3 Test Facility. Phase 1 of the subscale diffuser project, completed Sept. 24, was a series of 18 hot-fire tests using a 1,000-pound liquid oxygen and gaseous hydrogen thruster to verify maximum duration and repeatability for steam generation supporting the A-3 Test Stand project. The thruster is a stand-in for NASA's developing J-2X engine, to validate a 6 percent scale version of A-3's exhaust diffuser. Testing the J-2X at altitude conditions requires an enormous diffuser. Engineers will generate nearly 4,600 pounds per second of steam to reduce pressure inside A-3's test cell to simulate altitude conditions. A-3's exhaust diffuser has to be able to withstand regulated pressure, temperatures and the safe discharge of the steam produced during those tests. Before the real thing is built, engineers hope to work out any issues on the miniature version. Phase 2 testing is scheduled to begin this month.

Viking 1975 Orbiter Development Test Model/Lander Dynamic Test Model dynamic environmental testing - An overview

NASA Technical Reports Server (NTRS)

Milder, G.

1975-01-01

The current work presents an overview of the Viking 1975 environmental testing from an engineering standpoint. An extremely large vibration test fixture had to be designed, analyzed, and integrated into a test setup that employed hydrostatic bearings in a new fashion. A vibration control system was also required that would allow for thirty-six channels of sine-wave peak select control from acceleration, force-of-strain transducers. In addition, some 68 channels of peak limiting shutdown capability were needed for backup and monitoring of other data during the forced vibration test. Pretesting included analyses of the fixture design, overturning moment, control system capabilities, and response of the entire spacecraft/fixture/exciter system to the test environment. Closed-loop control for acoustic testing was a necessity due to the fact that the Viking spacecraft took up a major portion of the volume of the 10,000 cu ft chamber. The spacecraft emerged from testing undamaged.

Spore, J.W.; Cappiello, M.W.; Dotson, P.J.

The analytical support in 1985 for Cylindrical Core Test Facility (CCTF), Slab Core Test Facility (SCTF), and Upper Plenum Test Facility (UPTF) tests involves the posttest analysis of 16 tests that have already been run in the CCTF and the SCTF and the pretest analysis of 3 tests to be performed in the UPTF. Posttest analysis is used to provide insight into the detailed thermal-hydraulic phenomena occurring during the refill and reflood tests performed in CCTF and SCTF. Pretest analysis is used to ensure that the test facility is operated in a manner consistent with the expected behavior of anmore » operating full-scale plant during an accident. To obtain expected behavior of a plant during an accident, two plant loss-of-coolant-accident (LOCA) calculations were performed: a 200% cold-leg-break LOCA calculation for a 2772 MW(t) Babcock and Wilcox plant and a 200% cold-leg-break LOCA calculation for a 3315 MW(t) Westinghouse plant.

The design of the irradiation test vehicle (ITV) for the Advanced Test Reactor (ATR) has been completed. The main application for the ITV is irradiation testing of candidate fusion structural materials, including vanadium-base alloys, silicon carbide composites, and low-activation steels. Construction of the vehicle is underway at the Lockheed Martin Idaho Technology Company (LMITCO). Dummy test trains are being built for system checkout and fine-tuning. Reactor insertion of the ITV with the dummy test trains is scheduled for fall 1998. Barring unexpected difficulties, the ITV will be available for experiments in early 1999.

Flight Testing the X-36: The Test Pilots Perspective

NASA Technical Reports Server (NTRS)

Walker, Laurence A.

1997-01-01

The X-36 is a 28% scale, remotely piloted research aircraft, designed to demonstrate tailless fighter agility. Powered by a modified Williams International F-112 jet engine, the X-36 uses thrust vectoring and a fly-by-wire control system. Although too small for an onboard pilot, a full-sized remote cockpit was designed to virtually place the test pilot into the aircraft using a variety of innovative techniques. To date, 22 flights have been flown, successfully completing the second phase of testing. Handling qualities have been matching predictions; the test operation is flown similarly to that for full sized manned aircraft. All takeoffs, test maneuvers and landings are flown by the test pilot, affording a greater degree of flexibility and the ability to handle the inevitable unknowns which may occur during highly experimental test programs. The cockpit environment, cues, and display techniques used in this effort have proven to enhance the 'virtual' test pilot's awareness and have helped ensure a successful RPV test program.

Design and Testing of Suit Regulator Test Rigs

NASA Technical Reports Server (NTRS)

Campbell, Colin

2010-01-01

The next generation space suit requires additional capabilities for controlling and adjusting internal pressure compared to that of historical designs. Next generation suit pressures will range from slight pressure, for astronaut prebreathe comfort, to hyperbaric pressure levels for emergency medical treatment of decompression sickness. In order to test these regulators through-out their development life cycle, novel automated test rigs are being developed. This paper addresses the design philosophy, performance requirements, physical implementation, and test results with various units under test.

Comparison of intradermal dilutional testing, skin prick testing, and modified quantitative testing for common allergens.

PubMed

Peltier, Jacques; Ryan, Matthew W

2007-08-01

To compare and correlate wheal size using the Multi-Test II applicator with the endpoint obtained by intradermal dilutional testing (IDT) for 5 common allergens. To examine the safety of modified quantitative testing (MQT) for determining immunotherapy starting doses. Prospective comparative clinical study. A total of 134 subjects were simultaneously skin tested for immediate hypersensitivity using the Multi-Test II device and IDT. There was a 77% concordance between results from IDT and results from MQT. When there was a difference, MQT predicted a safer endpoint for starting immunotherapy in all but 2 cases. Wheal size by SPT is predictive of endpoint by IDT. MQT is nearly as effective as formal IDT in determining endpoint. Modified quantitative testing appears to be a safe alternative to IDT for determining starting doses for immunotherapy.

Test Analysis Guidelines

NASA Technical Reports Server (NTRS)

Jeng, Frank F.

2007-01-01

Development of analysis guidelines for Exploration Life Support (ELS) technology tests was completed. The guidelines were developed based on analysis experiences gained from supporting Environmental Control and Life Support System (ECLSS) technology development in air revitalization systems and water recovery systems. Analyses are vital during all three phases of the ELS technology test: pre-test, during test and post test. Pre-test analyses of a test system help define hardware components, predict system and component performances, required test duration, sampling frequencies of operation parameters, etc. Analyses conducted during tests could verify the consistency of all the measurements and the performance of the test system. Post test analyses are an essential part of the test task. Results of post test analyses are an important factor in judging whether the technology development is a successful one. In addition, development of a rigorous model for a test system is an important objective of any new technology development. Test data analyses, especially post test data analyses, serve to verify the model. Test analyses have supported development of many ECLSS technologies. Some test analysis tasks in ECLSS technology development are listed in the Appendix. To have effective analysis support for ECLSS technology tests, analysis guidelines would be a useful tool. These test guidelines were developed based on experiences gained through previous analysis support of various ECLSS technology tests. A comment on analysis from an experienced NASA ECLSS manager (1) follows: "Bad analysis was one that bent the test to prove that the analysis was right to begin with. Good analysis was one that directed where the testing should go and also bridged the gap between the reality of the test facility and what was expected on orbit."

A test matrix sequencer for research test facility automation

NASA Technical Reports Server (NTRS)

Mccartney, Timothy P.; Emery, Edward F.

1990-01-01

The hardware and software configuration of a Test Matrix Sequencer, a general purpose test matrix profiler that was developed for research test facility automation at the NASA Lewis Research Center, is described. The system provides set points to controllers and contact closures to data systems during the course of a test. The Test Matrix Sequencer consists of a microprocessor controlled system which is operated from a personal computer. The software program, which is the main element of the overall system is interactive and menu driven with pop-up windows and help screens. Analog and digital input/output channels can be controlled from a personal computer using the software program. The Test Matrix Sequencer provides more efficient use of aeronautics test facilities by automating repetitive tasks that were once done manually.

This photograph shows the Solid Propellant Test Article (SPTA) test stand with the Modified Nasa Motor (M-NASA) test article at the Marshall Space Flight Center (MSFC). The SPTA test stand, 12-feet wide by 12-feet long by 24-feet high, was built in 1989 to provide comparative performance data on nozzle and case insulation material and to verify thermostructural analysis models. A modified NASA 48-inch solid motor (M-NASA motor) with a 12-foot blast tube and 10-inch throat makes up the SPTA. The M-NASA motor is being used to evaluate solid rocket motor internal non-asbestos insulation materials, nozzle designs, materials, and new inspection techniques. New internal motor case instrumentation techniques are also being evaluated.

KRAS Testing

Activating point mutations in codons 12, 13, and 61 of the KRAS proto-oncogene are common in colorectal, non–small cell lung, pancreatic, and thyroid cancers. Constitutively activated KRAS mutations are strongly associated with a resistance to anti–epidermal growth factor receptor (EGFR) therapies, such as panitumumab and cetuximab used for treating metastatic colorectal carcinoma and EGFR tyrosine inhibitors used for advanced non–small cell lung cancers. Since anti-EGFR therapies are costly and may exert deleterious effects on individuals without activating mutations, KRAS mutation testing is recommended prior to the initiation of anti-EGFR therapy for these malignancies. The goal of this review is to summarize the KRAS mutation testing methods. Testing is now routinely requested in the clinical practice to provide data to assign the most appropriate anticancer chemotherapy for each given patient. Review of the most relevant literature was performed. Several areas were considered: ordering of the test, selection of the sample to be tested, and review of the testing methodologies. We found that several different methods are used for clinical KRAS mutation testing. Each of the methodologies is described, and information is provided about their performance, cost, turnaround times, detection limits, sensitivities, and specificities. We also provided “tips” for the appropriate selection and preparation of the sample to be tested. This is an important aspect of KRAS testing for clinical use, as the results of the test will affect clinical decisions with consequences for the patient. PMID:23264846

Cluster Development Test 2: An Assessment of a Failed Test

NASA Technical Reports Server (NTRS)

Machin, Ricardo A.; Evans, Carol T.

2009-01-01

On 31 July 2008 the National Aeronautics and Space Administration Crew Exploration Vehicle Parachute Assembly System team conducted the final planned cluster test of the first generation parachute recovery system design. The two primary test objectives were to demonstrate the operation of the complete parachute system deployed from a full scale capsule simulator and to demonstrate the test technique of separating the capsule simulator from the Low Velocity Air Drop pallet used to extract the test article from a United States Air Force C-17 aircraft. The capsule simulator was the Parachute Test Vehicle with an accurate heat shield outer mold line and forward bay compartment of the Crew Exploration Vehicle Command Module. The Parachute Test Vehicle separated cleanly from the pallet following extraction, but failed to reach test conditions resulting in the failure of the test and the loss of the test assets. No personnel were injured. This paper will discuss the design of the test and the findings of the team that investigated the test, including a discussion of what were determined to be the root causes of the failure.

From optics testing to micro optics testing

NASA Astrophysics Data System (ADS)

Brock, Christian; Dorn, Ralf; Pfund, Johannes

2017-10-01

Testing micro optics, i.e. lenses with dimensions down to 0.1mm and less, with high precision requires a dedicated design of the testing device, taking into account propagation and wave-optical effects. In this paper, we discuss testing methods based on Shack-Hartmann wavefront technology for functional testing in transmission and for the measurement of surface shape in reflection. As a first example of more conventional optics testing, i.e. optics in the millimeter range, we present the measurement of binoculars in transmission, and discuss the measured wave aberrations and imaging quality. By repeating the measurement at different wavelengths, information on chromatic effects is retrieved. A task that is often tackled using Shack-Hartman wavefront sensors is the alignment of collimation optics in front of a light source. In case of a micro-optical collimation unit with a 1/e² beam diameter of ca. 1mm, we need adapted relay optics for suitable beam expansion and well-defined imaging conditions. In this example, we will discuss the alignment process and effects of the relay optics magnification, as well as typical performance data. Oftentimes, micro optics are fabricated not as single pieces, but as mass optics, e.g. by lithographic processes. Thus, in order to reduce tooling and alignment time, an automated test procedure is necessary. We present an approach for the automated testing of wafer- or tray-based micro optics, and discuss transmission and reflection measurement capabilities. Exemplary performance data is shown for a sample type with 30 microns in diameter, where typical repeatabilities of a few nanometers (rms) are reached.

The integrated Flight Test 4 (FT4) will gather data for the UAS researchers Sense and Avoid systems (referred to as Detect and Avoid in the RTCA SC 228 ToR) algorithms and pilot displays for candidate UAS systems in a relevant environment. The technical goals of FT4 are to: 1) perform end-to-end traffic encounter test of pilot guidance generated by DAA algorithms; 2) collect data to inform the initial Minimum Operational Performance Standards (MOPS) for Detect and Avoid systems. FT4 objectives and test infrastructure builds from previous UAS project simulations and flight tests. NASA Ames (ARC), NASA Armstrong (AFRC), and NASA Langley (LaRC) Research Centers will share responsibility for conducting the tests, each providing a test lab and critical functionality. UAS-NAS project support and participation on the 2014 flight test of ACAS Xu and DAA Self Separation (SS) significantly contributed to building up infrastructure and procedures for FT3 as well. The DAA Scripted flight test (FT4) will be conducted out of NASA Armstrong over an eight-week period beginning in April 2016.

Performance tests.

Wetherell, A

1996-01-01

This paper discusses the use of psychological performance tests to assess the effects of environmental stressors. The large number and the variety of performance tests are illustrated, and the differences between performance tests and other psychological tests are described in terms of their design, construction, use, and purpose. The stressor emphasis is on the effects of drugs since that is where most performance tests have found their main application, although other stressors, e.g., fatigue, toxic chemicals, are mentioned where appropriate. Diazepam is used as an example. There is no particular performance emphasis since the tests are intended to have wide applicability. However, vehicle-driving performance is discussed because it has been the subject of a great deal of research and is probably one of the most important areas of application. Performance tests are discussed in terms of the four main underlying models--factor analysis, general information processing, multiple resource and strategy models, and processing-stage models--and in terms of their psychometric properties--sensitivity, reliability, and content, criterion, construct, and face validity. Some test taxonomies are presented. Standardization is also discussed with reference to the reaction time, mathematical processing, memory search, spatial processing, unstable tracking, verbal processing, and dual task tests used in the AGARD STRES battery. Some comments on measurement strengths and appropriate study designs and methods are included. PMID:9182033

1989-02-01

All new and retrofit installations of Halon 1301 (CBrF3) total flooding fire protection systems in shipboard machinery spaces require full acceptance discharge test. It is desirable to use a suitable simulant test gas in these tests in view of current and future regulation of Halon 1301. Sulfur hexafluoride, SF6, and chlorodifluromethane R-22, were identified as candidate simulants on the basis of their similarity in physical properties to Halon 1301. These two candidates were then evaluated on the basis of leakage from an enclosure. SF6 was determined to be an excellent simulant for Halon 1301 when considering leakage from an enclosure. Further testing of SF6 and R-22 is planned for other important aspects of Halon 1301 systems, i.e., flow hydraulics, initial mixing.

[Pre-test and post-test probabilities. Who cares?].

PubMed

Steurer, Johann

2009-01-01

The accuracy of a diagnostic test, i.e. abdomen ultrasound in patients with suspected acute appendicitis, is described in the terms of sensitivity and specificity. According to eminent textbooks physicians should use the values of the sensitivity and specificity of a test in their diagnostic reasoning. Physician's estimate, after taking the history, the pretest-probability of the suspected illness, order one or more tests and then calculate the respective posttest-probability. In practice physicians almost never follow this line of thinking. The main reasons are; to estimate concrete illness probabilities is difficult, the values for the sensitivity and specificity of a test are most often not known by physicians and calculations during daily practice are intricate. Helpful for busy physicians are trustworthy expert recommendations which test to apply in which clinical situation.

Access-in-turn test architecture for low-power test application

NASA Astrophysics Data System (ADS)

Wang, Weizheng; Wang, JinCheng; Wang, Zengyun; Xiang, Lingyun

2017-03-01

This paper presents a novel access-in-turn test architecture (AIT-TA) for testing of very large scale integrated (VLSI) designs. In the proposed scheme, each scan cell in a chain receives test data from shift-in line in turn while pushing its test response to the shift-out line. It solves the power problem of conventional scan architecture to a great extent and suppresses significantly the switching activity during shift and capture operation with acceptable hardware overhead. Thus, it can help to implement the test at much higher operation frequencies resulting shorter test application time. The proposed test approach enhances the architecture of conventional scan flip-flops and backward compatible with existing test pattern generation and simulation techniques. Experimental results obtained for some larger ISCAS'89 and ITC'99 benchmark circuits illustrate effectiveness of the proposed low-power test application scheme.

Virtual Shaker Testing: Simulation Technology Improves Vibration Test Performance

NASA Technical Reports Server (NTRS)

Ricci, Stefano; Peeters, Bart; Fetter, Rebecca; Boland, Doug; Debille, Jan

2008-01-01

In the field of vibration testing, the interaction between the structure being tested and the instrumentation hardware used to perform the test is a critical issue. This is particularly true when testing massive structures (e.g. satellites), because due to physical design and manufacturing limits, the dynamics of the testing facility often couples with the test specimen one in the frequency range of interest. A further issue in this field is the standard use of a closed loop real-time vibration control scheme, which could potentially shift poles and change damping of the aforementioned coupled system. Virtual shaker testing is a novel approach to deal with these issues. It means performing a simulation which closely represents the real vibration test on the specific facility by taking into account all parameters which might impact the dynamic behavior of the specimen. In this paper, such a virtual shaker testing approach is developed. It consists of the following components: (1) Either a physical-based or an equation-based coupled electro-mechanical lumped parameter shaker model is created. The model parameters are obtained from manufacturer's specifications or by carrying out some dedicated experiments; (2) Existing real-time vibration control algorithm are ported to the virtual simulation environment; and (3) A structural model of the test object is created and after defining proper interface conditions structural modes are computed by means of the well-established Craig-Bampton CMS technique. At this stage, a virtual shaker test has been run, by coupling the three described models (shaker, control loop, structure) in a co-simulation routine. Numerical results have eventually been correlated with experimental ones in order to assess the robustness of the proposed methodology.

Test-to-test variability in motor activity during the suggested immobilization test in restless legs patients.

PubMed

Haba-Rubio, José; Sforza, Emilia

2006-10-01

To evaluate the test-to-test variability of the suggested immobilization test (SIT) in patients with restless legs syndrome (RLS). Twenty patients with primary RLS (12 men and eight women; age: 53.3+/-11.3 years) were selected for the study. We compared the results of two SITs performed on two consecutive evenings prior to polysomnographic recordings. Overall, the periodic leg movement index during the SIT (SIT PLM) and the SIT PLM index associated with sensory manifestations (SIT PLM+) were not significantly different between tests. The number of PLM sequences per SIT, the mean PLM duration and the PLM interval did not significantly change between the two consecutive tests. The pattern of temporal evolution of motor activity across the SIT was very reproducible, SIT PLM showing a clear tendency to a progressive increase across the test, with the SIT PLM+ index decreasing in the second half of the test. Despite good reproducibility, there were marked intra-individual differences. Considering the proposed cut-off value of 12 for the SIT PLM index to confirm RLS, 11 patients were positive at the first test and four additional patients became positive at the second test. SIT PLM index changes did not correlate with age, severity of disease and polysomnographic measures. Quantitative analysis of motor activity during two consecutive SITs in RLS patients showed a significant inter-test intra-individual variability unrelated to demographic, clinical or polysomnographic parameters. SIT PLM index variability suggests that a single test would not be sensitive enough for diagnostic purposes in unclear cases and that new criteria need to be applied to increase its specificity and sensitivity.

Predictive testing for Huntington's disease: relationship with partners after testing.

PubMed

Decruyenaere, M; Evers-Kiebooms, G; Cloostermans, T; Boogaerts, A; Demyttenaere, K; Dom, R; Fryns, J P

2004-01-01

This study focuses on the partner relationship of tested persons, 5 years after their predictive test result for Huntington's disease (HD). We describe changes in marital status, quality of the relationship, and perceived changes in the relationship. Twenty-six carriers, 14 of their partners, 33 non-carriers, and 17 of their partners participated in the study. Qualitative and quantitative methods were used. For the majority of tested persons (about 70%), the marital status was unchanged 5 years post test. Overall, carriers rated the quality of the relationship higher than their partners did and they perceived more positive changes. Qualitative data show that a test result leading to changed roles may induce significant marital distress. Another consequence of the test may be the changes in dynamics in asymptomatic carrier couples. A pre-test discussion of the possible impact of the test result on the relationship should result in a better preparation for and more understanding of the reactions after testing. Counselling after testing should stimulate an open communication between partners with consideration of needs and anxieties of both partners.

Propulsion Ground Testing with High Test Peroxide: Lessons Learned

NASA Technical Reports Server (NTRS)

Bruce, Robert; Taylor, Gary; Taliancich, Paula

2002-01-01

Propulsion Ground Testing with High Test Peroxide (85 to 98% concentration) began at the NASA John C. Stennis Space Center in calendar year 1998, when the E3 Test Facility was modified to accomodate hydrogen peroxide (H2O2) in order to suport the research and development testing of the USAF Upper Stage Flight Experiment rocket engine. Since that time, efforts have continued to provide actual and planned test services to various customers, both U.S. Government and Commercial, in the ground test of many test articles, ranging from gas generators, to catalyst beds, to turbomachinery, to main injectors, to combustion chambers, to integrated rocket engines, to integrated stages. Along this path, and over the past 4 years, there has been both the rediscovery of previously learned lessons, through literature search, archive review, and personal interviews, as well as the learning of many new lessons as new areas are explored and new endeavors are tried. This paper will summarize those lessons learned in an effort to broaden the knowledge base as High Test Peroxide is considered more widely for use in rocket propulsion applications.

In Japan, understanding the environmental persistence of chemicals is very important for risk assessment, and ready biodegradability tests are mainly conducted according to the Organisation for Economic Co-operation and Development test guideline 301C. However, the highest test concentration specified in test guideline 301C, 100 mg/L, may cause microbial toxicity and incomplete biodegradation. The authors performed test guideline 301C tests at test concentrations of 30 mg/L for 13 substances that were readily biodegradable in ready biodegradability tests but not in test guideline 301C tests. Of the 5 substances with potential to cause microbial toxicity at 100 mg/L, the percentage of biodegradation of sodium dimethyldithiocarbamate, 4-chloro-3-cresol (CC), thymol (THY), and p-tert-butyl-α-methylbenzenepropionaldehyde measured by biochemical oxygen demand (BOD) increased in the test guideline 301C test at 30 mg/L, suggesting a reduction in toxicity effects. Furthermore, CC and THY met the criteria for ready biodegradability, which are more than 60% of biodegradation by BOD and a 10-d window. Of the 8 substances with a low potential for causing microbial toxicity at 100 mg/L, the percentage of biodegradation of only 2-(diethylamino)ethanol increased in the test guideline 301C test at 30 mg/L. Employing a lower test concentration in the standard test guideline 301C test will contribute to improvement of consistency between results of a test guideline 301C test and other ready biodegradability tests. © 2015 SETAC.

Propfan test assessment testbed aircraft flutter model test report

NASA Technical Reports Server (NTRS)

Jenness, C. M. J.

1987-01-01

The PropFan Test Assessment (PTA) program includes flight tests of a propfan power plant mounted on the left wind of a modified Gulfstream II testbed aircraft. A static balance boom is mounted on the right wing tip for lateral balance. Flutter analyses indicate that these installations reduce the wing flutter stabilizing speed and that torsional stiffening and the installation of a flutter stabilizing tip boom are required on the left wing for adequate flutter safety margins. Wind tunnel tests of a 1/9th scale high speed flutter model of the testbed aircraft were conducted. The test program included the design, fabrication, and testing of the flutter model and the correlation of the flutter test data with analysis results. Excellent correlations with the test data were achieved in posttest flutter analysis using actual model properties. It was concluded that the flutter analysis method used was capable of accurate flutter predictions for both the (symmetric) twin propfan configuration and the (unsymmetric) single propfan configuration. The flutter analysis also revealed that the differences between the tested model configurations and the current aircraft design caused the (scaled) model flutter speed to be significantly higher than that of the aircraft, at least for the single propfan configuration without a flutter boom. Verification of the aircraft final design should, therefore, be based on flutter predictions made with the test validated analysis methods.

Diagnostic laboratory tests are routinely defined in terms of their sensitivity, specificity, and ease of use. But the actual clinical impact of a diagnostic test also depends on its availability and price. This is especially true in resource-limited settings such as sub-Saharan Africa. We present a first-of-its-kind report of diagnostic test types, availability, and prices in Kampala, Uganda. Test types (identity) and availability were based on menus and volumes obtained from clinical laboratories in late 2011 in Kampala using a standard questionnaire. As a measure of test availability, we used the Availability Index (AI). AI is the combined daily testing volumes of laboratories offering a given test, divided by the combined daily testing volumes of all laboratories in Kampala. Test prices were based on a sampling of prices collected in person and via telephone surveys in 2015. Test volumes and menus were obtained for 95% (907/954) of laboratories in Kampala city. These 907 laboratories offered 100 different test types. The ten most commonly offered tests in decreasing order were Malaria, HCG, HIV serology, Syphilis, Typhoid, Urinalysis, Brucellosis, Stool Analysis, Glucose, and ABO/Rh. In terms of AI, the 100 tests clustered into three groups: high (12 tests), moderate (33 tests), and minimal (55 tests) availability. 50% and 36% of overall availability was provided through private and public laboratories, respectively. Point-of-care laboratories contributed 35% to the AI of high availability tests, but only 6% to the AI of the other tests. The mean price of the most commonly offered test types was $2.62 (range $1.83-$3.46). One hundred different laboratory test types were in use in Kampala in late 2011. Both public and private laboratories were critical to test availability. The tests offered in point-of-care laboratories tended to be the most available tests. Prices of the most common tests ranged from $1.83-$3.46.

In India, men who have sex with men (MSM) and truck drivers are high-risk groups that often do not access HIV testing due to stigma and high mobility. This study evaluated a field testing package (FTP) that identified HIV positive participants through video pre-test counseling, OraQuick oral fluid HIV testing, and telephonic post-test counseling and then connected them to government facilities. 598 MSM and truck drivers participated in the FTP and completed surveys covering sociodemographics, HIV testing history, risk behaviors, and opinions on the FTP. Those who had previously been tested preferred traditional methods to video counseling. MSM and truck drivers equally preferred video counseling, although MSM who had been previously tested preferred traditional methods. Nearly all participants preferred oral testing. Rates of counseling completion and linkage to government centers were low, with one third of newly identified positives completing follow-up. With increased public-private coordination, this FTP could identify many hard-to-reach preliminary positive individuals and connect them to government testing and care. PMID:22827901

Ni-MH storage test and cycle life test

Dell, R. Dan; Klein, Glenn C.; Schmidt, David F.

1994-01-01

Gates Aerospace Batteries is conducting two long term test programs to fully characterize the NiMH cell technology for aerospace applications. The first program analyzes the effects of long term storage upon cell performance. The second program analyzes cycle life testing and preliminary production lot testing. This paper summarizes these approaches to testing the NiMH couple and culminates with initial storage and testing recommendations. Long term storage presents challenges to deter the adverse condition of capacity fade in NiMH cells. Elevated but stabilized pressures and elevated but stabilized end-of-charge voltages also appear to be a characteristic phenomenon of long term storage modes. However, the performance degradation is dependent upon specific characteristics of the metal-hydride alloy. To date, there is no objective evidence with which to recommend the proper method for storage and handling of NiMH cells upon shipment. This is particularly critical due to limited data points that indicate open circuit storage at room temperature for 60 to 90 days will result in irrecoverable capacity loss. Accordingly a test plan was developed to determine what method of mid-term to long-term storage will prevent irrecoverable capacity loss. The explicit assumption is that trickle charging at some rate above the self-discharge rate will prevent the irreversible chemical changes to the negative electrode that result in the irrecoverable capacity loss. Another premise is that lower storage temperatures, typically 0 C for aerospace customers, will impede any negative chemical reactions. Three different trickle charge rates are expected to yield a fairly flat response with respect to recoverable capacity versus baseline cells in two different modes of open circuit. Specific attributes monitored include: end-of-charge voltage, end-of-charge pressure, mid-point discharge voltage, capacity, and end-of-discharge pressure.

Software quality is of primary concern in all large-scale expert system development efforts. Building appropriate validation and test tools for ensuring software reliability of expert systems is therefore required. The Expert Systems Validation Associate (EVA) is a validation system under development at the Lockheed Artificial Intelligence Center. EVA provides a wide range of validation and test tools to check correctness, consistency, and completeness of an expert system. Testing a major function of EVA. It means executing an expert system with test cases with the intent of finding errors. In this paper, we describe many different types of testing such as function-based testing, structure-based testing, and data-based testing. We describe how appropriate test cases may be selected in order to perform good and thorough testing of an expert system.

Injecting Errors for Testing Built-In Test Software

NASA Technical Reports Server (NTRS)

Gender, Thomas K.; Chow, James

2010-01-01

Two algorithms have been conceived to enable automated, thorough testing of Built-in test (BIT) software. The first algorithm applies to BIT routines that define pass/fail criteria based on values of data read from such hardware devices as memories, input ports, or registers. This algorithm simulates effects of errors in a device under test by (1) intercepting data from the device and (2) performing AND operations between the data and the data mask specific to the device. This operation yields values not expected by the BIT routine. This algorithm entails very small, permanent instrumentation of the software under test (SUT) for performing the AND operations. The second algorithm applies to BIT programs that provide services to users application programs via commands or callable interfaces and requires a capability for test-driver software to read and write the memory used in execution of the SUT. This algorithm identifies all SUT code execution addresses where errors are to be injected, then temporarily replaces the code at those addresses with small test code sequences to inject latent severe errors, then determines whether, as desired, the SUT detects the errors and recovers

The Expeditionary Test Set - A fresh approach to automatic testing

NASA Astrophysics Data System (ADS)

Williams, D. L.; Austin, W. J.

This paper discusses the key design decisions and tradeoffs leading from the conceptual stage to the production version of the Expeditionary Test Set (ETS) for the USMC. This included a ten-month feasibility study program funded by the Naval Air Systems Command which culminated in the successful demonstration of a working tester model. The demonstration of the test set was preceded by a substantial re-thinking of conventional ATE test methods. Considerable discussion is devoted to the impact of test philosophy, both on the test set design and the overall effectiveness of avionic testing. Major architectural features of the test set are presented in some detail, and the many areas which break from traditional ATE design are emphasized.

2017-08-01

This study's primary aim was to examine ethnic differences in predictors of HIV testing among Black and White college students. We also examined ethnic differences in sexual risk behaviors and attitudes toward the importance of HIV testing. An analytic sample of 126 Black and 617 White undergraduatestudents aged 18-24 were analyzed for a subset of responses on the American College Health Association-National College Health Assessment II (ACHA-NCHA II) (2012) pertaining to HIV testing, attitudes about the importance of HIV testing, and sexual risk behaviors. Predictors of HIV testing behavior were analyzed using logistic regression. t tests and chi-square tests were performed to access differences in HIV test history, testing attitudes, and sexual risk behaviors. Black students had more positive attitudes toward testing and were more likely to have been tested for HIV compared to White students. A greater number of sexual partners and more positive HIV testing attitudes were significant predictors of HIV testing among White students, whereas relationship status predicted testing among Black students. Older age and history of ever having sex were significant predictors of HIV testing for both groups. There were no significant differences between groups in number of sexual partners or self-reports in history of sexual experience (oral, vaginal, or anal). Factors that influence HIV testing may differ across racial/ethnic groups. Findings support the need to consider racial/ethnic differences in predictors of HIV testing during the development and tailoring of HIV testing prevention initiatives targeting college students.

Logan, Andrew J; Wilkinson, Frances; Wilson, Hugh R; Gordon, Gael E; Loffler, Gunter

2016-02-01

This study aimed to develop a clinical test of face perception which is applicable to a wide range of patients and can capture normal variability. The Caledonian face test utilises synthetic faces which combine simplicity with sufficient realism to permit individual identification. Face discrimination thresholds (i.e. minimum difference between faces required for accurate discrimination) were determined in an "odd-one-out" task. The difference between faces was controlled by an adaptive QUEST procedure. A broad range of face discrimination sensitivity was determined from a group (N=52) of young adults (mean 5.75%; SD 1.18; range 3.33-8.84%). The test is fast (3-4 min), repeatable (test-re-test r(2)=0.795) and demonstrates a significant inversion effect. The potential to identify impairments of face discrimination was evaluated by testing LM who reported a lifelong difficulty with face perception. While LM's impairment for two established face tests was close to the criterion for significance (Z-scores of -2.20 and -2.27) for the Caledonian face test, her Z-score was -7.26, implying a more than threefold higher sensitivity. The new face test provides a quantifiable and repeatable assessment of face discrimination ability. The enhanced sensitivity suggests that the Caledonian face test may be capable of detecting more subtle impairments of face perception than available tests. Copyright © 2015 Elsevier Ltd.

This research explored the test-taking strategies associated with the Test of English for International Communication Speaking Test (TOEIC-S) and their relationship with test performance. Capitalizing on two sets of TOEIC-S and a custom-made strategy inventory, the researcher collected data from a total of 215 Taiwanese English learners consisting of 84 males and 131 females with an average age of 20.1 years (SD = 2.6). Quantitative data analysis gave rise to three major findings. First, TOEIC-S test-taking strategy use constituted a multi-faceted construct that involved multiple types of strategic behaviors. Second, these strategic behaviors matched those allowing test-takers to communicate both in real life and in the workplace. Third, communication strategy use and cognitive strategy use both contributed significantly to TOEIC-S performance. © The Author(s) 2016.

The James Webb Space Telescope (JWST) Secondary Mirror Assembly (SMA) is a circular 740mm diameter beryllium convex hyperboloid that has a 23.5nm-RMS (λ/27 RMS) on-orbit surface figure error requirement. The radius of curvature of the SMA is 1778.913mm+/-0.45mm and has a conic constant of -1.6598+/-0.0005. The on-orbit operating temperature of the JWST SMA is 22.5K. Ball Aerospace & Technologies Corp. (BATC) is under contract to Northrop Grumman Aerospace Systems (NGAS) to fabricate, assemble, and test the JWST SMA to its on-orbit requirements including the optical testing of the SMA at its cryogenic operating temperature. BATC has fabricated and tested an Aspheric Test Plate Lens (ATPL) that is an 870mm diameter fused silica lens used as the Fizeau optical reference in the ambient and cryogenic optical testing of the JWST Secondary Mirror Assembly (SMA). As the optical reference for the SMA optical test, the concave optical surface of the ATPL is required to be verified at the same 20K temperature range required for the SMA. In order to meet this objective, a state-of-the-art helium cryogenic testing facility was developed to support the optical testing requirements of a number of the JWST optical testing needs, including the ATPL and SMA. With the implementation of this cryogenic testing facility, the ATPL was successfully cryogenically tested and performed to less than 10nm-RMS (λ/63 RMS) surface figure uncertainty levels for proper reference backout during the SMA optical testing program.

Morris, D. Brent; Standley, Vaughn H.; Schuller, Michael J.

1992-01-01

The arrival of a Soviet TOPAZ-II space nuclear reactor affords the US space nuclear power (SNP) community the opportunity to study an assembled thermionic conversion power system. The TOPAZ-II will be studied via the Thermionic System Evaluation Test (TSET) Project. This paper is devoted to the discussion of TSET test development as related to the objectives contained in the TSET Project Plan (Standley et al. 1991). The objectives contained in the Project Plan are the foundation for scheduled TSET tests on TOPAZ-II and are derived from the needs of the Air Force Thermionic SNP program. Our ability to meet the objectives is bounded by unique constraints, such as procurement requirements, operational limitations, and necessary interaction between US and Soviet Scientists and engineers. The fulfillment of the test objectives involves a thorough methodology of test scheduling and data managment. The overall goals for the TSET program are gaining technical understanding of a thermionic SNP system and demonstrating the capabilities and limitations of such a system while assisting in the training of US scientist and engineers in preparation for US SNP system testing. Tests presently scheduled as part of TSET include setup, demonstration, and verification tests; normal and off-normal operating test, and system and component performance tests.

Fisher, Mark F.; King, Richard F.; Chenevert, Donald J.

1998-01-01

The need for low cost access to space has initiated the development of low cost liquid rocket engine and propulsion system hardware at the Marshall Space Flight Center. This hardware will be tested at the Stennis Space Center's B-2 test stand. This stand has been reactivated for the testing of the Marshall designed Fastrac engine and the Propulsion Test Article. The RP-1 and LOX engine is a turbopump fed gas generator rocket with an ablative nozzle which has a thrust of 60,000 lbf. The Propulsion Test Article (PTA) is a test bed for low cost propulsion system hardware including a composite RP-I tank, flight feedlines and pressurization system, stacked in a booster configuration. The PTA is located near the center line of the B-2 test stand, firing vertically into the water cooled flame deflector. A new second position on the B-2 test stand has been designed and built for the horizontal testing of the Fastrac engine in direct support of the X-34 launch vehicle. The design and integration of these test facilities as well as the coordination which was required between the two Centers is described and lessons learned are provided. The construction of the horizontal test position is discussed in detail. The activation of these facilities is examined and the major test milestones are described.

Although the scope of flight test engineering efforts may vary among organizations, all point to a common theme: flight test engineering is an interdisciplinary effort to test an asset in its operational flight environment. Upfront planning where design, implementation, and test efforts are clearly aligned with the flight test objective are keys to success. This chapter provides a top level perspective of flight test engineering for the non-expert. Additional research and reading on the topic is encouraged to develop a deeper understanding of specific considerations involved in each phase of flight test engineering.

Gun Testing Ballistics Issues for Insensitive Munitions Fragment Impact Testing

NASA Astrophysics Data System (ADS)

Baker, Ernest; Schultz, Emmanuel; NATO Munitions Safety Information Analysis Centre Team

2017-06-01

The STANAG 4496 Ed. 1 Fragment Impact, Munitions Test Procedure is normally conducted by gun launching a projectile for attack against a munition. The purpose of this test is to assess the reaction of a munition impacted by a fragment. The test specifies a standardized projectile (fragment) with a standard test velocity of 2530+/-90 m/s, or an alternate test velocity of 1830+/-60 m/s. The standard test velocity can be challenging to achieve and has several loosely defined and undefined characteristics that can affect the test item response. This publication documents the results of an international review of the STANAG 4496 related to the fragment impact test. To perform the review, MSIAC created a questionnaire in conjunction with the custodian of this STANAG and sent it to test centers. Fragment velocity variation, projectile tilt upon impact and aim point variation were identified as observed gun testing issues. Achieving 2530 m/s consistently and cost effectively can be challenging. The aim point of impact of the fragment is chosen with the objective of obtaining the most violent reaction. No tolerance for aim point is specified, although aim point variation can be a source for IM response variation. Fragment tilt on impact is also unspecified. The standard fragment fabricated from a variety of different steels which have a significant margin for mechanical properties. These, as well as other gun testing issues, have significant implications to resulting IM response.

Dynamic Response Testing in an Electrically Heated Reactor Test Facility

NASA Astrophysics Data System (ADS)

Bragg-Sitton, Shannon M.; Morton, T. J.

2006-01-01

Non-nuclear testing can be a valuable tool in the development of a space nuclear power or propulsion system. In a non-nuclear test bed, electric heaters are used to simulate the heat from nuclear fuel. Standard testing allows one to fully assess thermal, heat transfer, and stress related attributes of a given system, but fails to demonstrate the dynamic response that would be present in an integrated, fueled reactor system. The integration of thermal hydraulic hardware tests with simulated neutronic response provides a bridge between electrically heated testing and fueled nuclear testing. By implementing a neutronic response model to simulate the dynamic response that would be expected in a fueled reactor system, one can better understand system integration issues, characterize integrated system response times and response characteristics, and assess potential design improvements at a relatively small fiscal investment. Initial system dynamic response testing was demonstrated on the integrated SAFE-100a heat pipe (HP) cooled, electrically heated reactor and heat exchanger hardware, utilizing a one-group solution to the point kinetics equations to simulate the expected neutronic response of the system. Reactivity feedback calculations were then based on a bulk reactivity feedback coefficient and measured average core temperature. This paper presents preliminary results from similar dynamic testing of a direct drive gas cooled reactor system (DDG), demonstrating the applicability of the testing methodology to any reactor type and demonstrating the variation in system response characteristics in different reactor concepts. Although the HP and DDG designs both utilize a fast spectrum reactor, the method of cooling the reactor differs significantly, leading to a variable system response that can be demonstrated and assessed in a non-nuclear test facility. Planned system upgrades to allow implementation of higher fidelity dynamic testing are also discussed. Proposed DDG

Calibrating/testing meters in hot water test bench VM7

NASA Astrophysics Data System (ADS)

Kling, E.; Stolt, K.; Lau, P.; Mattiasson, K.

A Hot Water Test Bench, VM7, has been developed and constructed for the calibration and testing of volume and flowmeters, in a project at the National Volume Measurement Laboratory at the Swedish National Testing and Research Institute. The intended area of use includes use as a reference at audit measurements, e.g. for accredited laboratories, calibration of meters for the industry and for the testing of hot water meters. The objective of the project, which was initiated in 1989, was to design equipment with stable flow and with a minimal temperature drop even at very low flow rates. The principle of the design is a closed system with two pressure tanks at different pressures. The water is led from the high pressure tank through the test object and the volume standard, in the form of master meters or a piston prover alternatively, to the low pressure tank. Calibrations/tests are made comparing the indication of the test object to that of master meters covering the current flow rate. These are, in the same test cycle, calibrated to the piston prover. Alternatively, the test object can be calibrated directly to the piston prover.

Collett, C.

1976-01-01

A test system was built and several short term tests were completed. The test system included, in addition to the 30-cm ion thruster, a console for powering the thruster and monitoring performance, a vacuum facility for simulating a space environment, and a storage and feed system for the thruster propellant. This system was used to perform three short term tests (one 100-hour and two 500-hour tests), an 1108-hour endurance test which was aborted by a vacuum facility failure, and finally the 10,000-hour endurance test. In addition to the two 400 series thrusters which were used in the short term and 1100-hour tests, four more 400 series thrusters were fabricated, checked out, and delivered to NASA. Three consoles similar to the one used in the test program were also fabricated and delivered.

Rock, Michael J.; Makholm, Linda; Eickhoff, Jens

2015-01-01

Background Conventional methods of sweat testing are time consuming and have many steps that can and do lead to errors. This study compares conventional sweat testing to a new quantitative method, the CF Quantum® (CFQT) sweat test. This study tests the diagnostic accuracy and analytic validity of the CFQT. Methods Previously diagnosed CF patients and patients who required a sweat test for clinical indications were invited to have the CFQT test performed. Both conventional sweat testing and the CFQT were performed bilaterally on the same day. Pairs of data from each test are plotted as a correlation graph and Bland Altman plot. Sensitivity and specificity were calculated as well as the means and coefficient of variation by test and by extremity. After completing the study, subjects or their parents were asked for their preference of the CFQT and conventional sweat testing. Results The correlation coefficient between the CFQT and conventional sweat testing was 0.98 (95% confidence interval: 0.97–0.99). The sensitivity and specificity of the CFQT in diagnosing CF was 100% (95% confidence interval: 94–100%) and 96% (95% confidence interval: 89–99%), respectively. In one center in this three center multicenter study, there were higher sweat chloride values in patients with CF and also more tests that were invalid due to discrepant values between the two extremities. The percentage of invalid tests was higher in the CFQT method (16.5%) compared to conventional sweat testing (3.8%)(p < 0.001). In the post-test questionnaire, 88% of subjects/parents preferred the CFQT test. Conclusions The CFQT is a fast and simple method of quantitative sweat chloride determination. This technology requires further refinement to improve the analytic accuracy at higher sweat chloride values and to decrease the number of invalid tests. PMID:24862724

Stevinson, Kendall; Martin, Eugene G; Marcella, Stephen; Paul, Sindy M

2011-12-01

Before 2009, New Jersey (NJ) publicly funded counseling and testing sites (CTS) tested for HIV using a single rapid test followed, when positive, by a Western Blot (WB) for confirmation. With this strategy, 74.8% of confirmed positive clients returned to receive test results. To improve the client notification rate at these centers, the New Jersey (NJ) Division of HIV, STD and TB Services (DHSTS) implemented a rapid testing algorithm (RTA) which utilizes a second, different, rapid test to verify a preliminary positive. To compare the cost-effectiveness of the two testing algorithms. This was a retrospective cost-effectiveness analysis. New Jersey HIV Rapid Testing Support Program (NJHIV) records, DHSTS grant documents, counseling time estimates from an online survey of site supervisors. Costs included test kits and personnel costs from month of RTA implementation through 11/30 in 2008 and 2009. The incremental cost of the RTA was calculated per additional percent of positive clients who were notified and per day earlier notification. In 2008, 215 of 247 clients with a positive rapid HIV test were confirmed positive by WB. 90.9% of clients were notified a mean of 11.4 days after their initial test. 12 refused confirmatory WB. In 2009, 152 of 170 clients with one positive rapid test had a confirmatory second positive rapid test and were notified on the same day. The incremental cost of the RTA was $20.31 per additional positive person notified and $24.31 per day earlier notification or $3.23 per additional positive person and $3.87 per day earlier notification if the WB were eliminated. The RTA is a cost-effective strategy achieving 100% notification of newly HIV positive clients a mean of 11.4 days earlier compared to standard testing. Copyright © 2011 Elsevier B.V.

The testing effect for mediator final test cues and related final test cues in online and laboratory experiments.

PubMed

Coppens, Leonora C; Verkoeijen, Peter P J L; Bouwmeester, Samantha; Rikers, Remy M J P

2016-05-31

The testing effect is the finding that information that is retrieved during learning is more often correctly retrieved on a final test than information that is restudied. According to the semantic mediator hypothesis the testing effect arises because retrieval practice of cue-target pairs (mother-child) activates semantically related mediators (father) more than restudying. Hence, the mediator-target (father-child) association should be stronger for retrieved than restudied pairs. Indeed, Carpenter (2011) found a larger testing effect when participants received mediators (father) than when they received target-related words (birth) as final test cues. The present study started as an attempt to test an alternative account of Carpenter's results. However, it turned into a series of conceptual (Experiment 1) and direct (Experiment 2 and 3) replications conducted with online samples. The results of these online replications were compared with those of similar existing laboratory experiments through small-scale meta-analyses. The results showed that (1) the magnitude of the raw mediator testing effect advantage is comparable for online and laboratory experiments, (2) in both online and laboratory experiments the magnitude of the raw mediator testing effect advantage is smaller than in Carpenter's original experiment, and (3) the testing effect for related cues varies considerably between online experiments. The variability in the testing effect for related cues in online experiments could point toward moderators of the related cue short-term testing effect. The raw mediator testing effect advantage is smaller than in Carpenter's original experiment.

2016-01-01

The desire and ability to fly Unmanned Aircraft Systems (UAS) in the National Airspace System (NAS) is of increasing urgency. The application of unmanned aircraft to perform national security, defense, scientific, and emergency management are driving the critical need for less restrictive access by UAS to the NAS. UAS represent a new capability that will provide a variety of services in the government (public) and commercial (civil) aviation sectors. The growth of this potential industry has not yet been realized due to the lack of a common understanding of what is required to safely operate UAS in the NAS. NASA's UAS Integration in the NAS Project is conducting research in the areas of Separation Assurance/Sense and Avoid Interoperability (SSI), Human Systems Integration (HSI), and Communications (Comm), and Certification to support reducing the barriers of UAS access to the NAS. This research is broken into two research themes namely, UAS Integration and Test Infrastructure. UAS Integration focuses on airspace integration procedures and performance standards to enable UAS integration in the air transportation system, covering Detect and Avoid (DAA) performance standards, command and control performance standards, and human systems integration. The focus of Test Infrastructure is to enable development and validation of airspace integration procedures and performance standards, including integrated test and evaluation. In support of the integrated test and evaluation efforts, the Project will develop an adaptable, scalable, and schedulable relevant test environment capable of evaluating concepts and technologies for unmanned aircraft systems to safely operate in the NAS. To accomplish this task, the Project is conducting a series of human-in-the-loop (HITL) and flight test activities that integrate key concepts, technologies and/or procedures in a relevant air traffic environment. Each of the integrated events will build on the technical achievements, fidelity, and

Dynamic testing and test anxiety amongst gifted and average-ability children.

Vogelaar, Bart; Bakker, Merel; Elliott, Julian G; Resing, Wilma C M

2017-03-01

Dynamic testing has been proposed as a testing approach that is less disadvantageous for children who may be potentially subject to bias when undertaking conventional assessments. For example, those who encounter high levels of test anxiety, or who are unfamiliar with standardized test procedures, may fail to demonstrate their true potential or capabilities. While dynamic testing has proven particularly useful for special groups of children, it has rarely been used with gifted children. We investigated whether it would be useful to conduct a dynamic test to measure the cognitive abilities of intellectually gifted children. We also investigated whether test anxiety scores would be related to a progression in the children's test scores after dynamic training. Participants were 113 children aged between 7 and 8 years from several schools in the western part of the Netherlands. The children were categorized as either gifted or average-ability and split into an unguided practice or a dynamic testing condition. The study employed a pre-test-training-post-test design. Using linear mixed modelling analysis with a multilevel approach, we inspected the growth trajectories of children in the various conditions and examined the impact of ability and test anxiety on progression and training benefits. Dynamic testing proved to be successful in improving the scores of the children, although no differences in training benefits were found between gifted and average-ability children. Test anxiety was shown to influence the children's rate of change across all test sessions and their improvement in performance accuracy after dynamic training. © 2016 The British Psychological Society.

Preliminary DICOM acceptance testing using the central test node

NASA Astrophysics Data System (ADS)

Chimiak, William J.

1996-05-01

The Bowman Gray School of Medicine of Wake Forest University (BGSM) is installing clinical DICOM workstations and DICOM film digitizers for use in a telemedicine trial over the North Carolina ATM infrastructure. Acquiring equipment thought to be DICOM compliant, but which does not live up to expectations and possibly fails to interoperate with other DICOM equipment, is a concern. In cooperation with RSNA and the Mallinckrodt Institute of Radiology of the Washington University School of Medicine (MIR), BGSM made acceptance of the CEMAX workstations for the telemedicine trial contingent upon a satisfactory test with the MIR central test node (CTN). During the test, both engineers never left their hospitals during the tests drastically cutting travel and per diem costs and valuable time. The successful results exceeded expectations. Images were not only passed back and forth to the CTN by both the CEMAX clinical workstation and the quality assurance workstation, but images arriving from the CTN were entered into the CEMAX clinical database without operator intervention. It was expected that the images would transfer, but the placement into the database, although reasonable to expect, actually occurred. This live test from an independent test source exhibited the ease with which the CEMAX workstations handled the DICOM images in their systems. In the test, the CEMAX workstations were configured as an exporter of DICOM images at BGSM. The CTN was entered in the configuration of the CEMAX workstations as a source of DICOM images. The test was to ensure that plain film, computed tomography, and magnetic resonance images could be easily exchanged between workstations electronically. This paper describes the procedure for using the CTN to provide preliminary testing of DICOM equipment.

2015-03-01

Workplace Drug Testing (WDT) in Italy includes two levels of monitoring: a first stage concerning drug testing on urine samples and a second involving both urine and hair analysis. The second stage is performed only on workers who tested positive at the first level. We analyzed urine and hair specimens from 120 workers undergoing second-level testing between 2009 and 2012. Eighty percent of them had tested positive for cannabinoids during the first level analysis, and 15.8% for cocaine. Both urine and hair samples were analyzed in order to find the following drugs of abuse: amphetamines, buprenorphine, cannabinoids, cocaine, ecstasy, methadone, and opiates. Urine analyses were performed by immunological screening (EMIT); urine confirmatory tests and hair analyses were performed by gas chromatography-mass spectrometry (GC-MS). As regards second-stage testing on urine samples, 71.2% of workers were always negative, whereas 23.9% tested positive at least once for cannabinoids and 2.5% for cocaine. Hair analyses produced surprising results: 61.9% of hair samples tested negative, only 6.2% tested positive for cannabinoids, whereas 28.8% tested positive for cocaine. These findings confirm that second-level surveillance of WDT, which includes hair analysis, is very effective because it highlights drug intake - sometimes heavy - that cannot be revealed only through urine analyses. The employees for whom drug addiction is proved can begin rehabilitation, while keeping their job. Eventually, our results confirmed the widespread and undeclared use of cocaine in Italy.

Further investigations of the W-test for pairwise epistasis testing.

PubMed

Howey, Richard; Cordell, Heather J

2017-01-01

Background: In a recent paper, a novel W-test for pairwise epistasis testing was proposed that appeared, in computer simulations, to have higher power than competing alternatives. Application to genome-wide bipolar data detected significant epistasis between SNPs in genes of relevant biological function. Network analysis indicated that the implicated genes formed two separate interaction networks, each containing genes highly related to autism and neurodegenerative disorders. Methods: Here we investigate further the properties and performance of the W-test via theoretical evaluation, computer simulations and application to real data. Results: We demonstrate that, for common variants, the W-test is closely related to several existing tests of association allowing for interaction, including logistic regression on 8 degrees of freedom, although logistic regression can show inflated type I error for low minor allele frequencies,  whereas the W-test shows good/conservative type I error control. Although in some situations the W-test can show higher power, logistic regression is not limited to tests on 8 degrees of freedom but can instead be tailored to impose greater structure on the assumed alternative hypothesis, offering a power advantage when the imposed structure matches the true structure. Conclusions: The W-test is a potentially useful method for testing for association - without necessarily implying interaction - between genetic variants disease, particularly when one or more of the genetic variants are rare. For common variants, the advantages of the W-test are less clear, and, indeed, there are situations where existing methods perform better. In our investigations, we further uncover a number of problems with the practical implementation and application of the W-test (to bipolar disorder) previously described, apparently due to inadequate use of standard data quality-control procedures. This observation leads us to urge caution in interpretation of the

Alkali metal thermoelectric converter operation in a recirculating test cell (RTC), which requires a small electromagnetic pump (EM) and a high-temperature beta-double-prime alumina-solid-electrolyte (BASE)-to-metal seal, is discussed. The design of a pump and an active metal braze seal and the initial operation of a cell using these components are described. The pump delivered 0.25 cu cm/min against a 28-psia head. A braze seal system was selected after shear strength tests of Ta or Nb brazed to BASE by a variety of fillers including TiCuNi, TiNi, and TiNiCr. The TiCuNi filler was chosen for environment cell testing and showed no failure or observable degradation after short-term tests up to 1055 K. The pump and the Nb/TiCuNi/BASE seal were used in a test that demonstrated all the operational functions of the RTC for the first time. An increase in the radiation reduction factor at constant input power was observed, indicating that the condenser was being wet by sodium resulting in an increased reflectivity.

A Boilerplate Capsule Test Technique for the Orion Parachute Test Program

NASA Technical Reports Server (NTRS)

Moore, James W.; Fraire, Usbaldo, Jr.

2013-01-01

The test program developing parachutes for the Orion/MPCV includes drop tests of a Parachute Test Vehicle designed to emulate the wake of the Orion capsule. Delivery of this test vehicle to the initial velocity, altitude, and orientation required for the test is a difficult problem involving multiple engineering disciplines. The available delivery of aircraft options imposed constraints on the test vehicle development and concept of operations. This paper describes the development of this test technique. The engineering challenges include the extraction from an aircraft and separation of two aerodynamically unstable vehicles, one of which will be delivered to a specific orientation with reasonably small rates. The desired attitude is achieved by precisely targeting the separation point using on-board monitoring of the motion. The design of the test vehicle is described. The trajectory simulations and other analyses used to develop this technique and predict the behavior of the test article are reviewed in detail. The application of the technique on several successful drop tests is summarized.

Software testing

NASA Astrophysics Data System (ADS)

Price-Whelan, Adrian M.

2016-01-01

Now more than ever, scientific results are dependent on sophisticated software and analysis. Why should we trust code written by others? How do you ensure your own code produces sensible results? How do you make sure it continues to do so as you update, modify, and add functionality? Software testing is an integral part of code validation and writing tests should be a requirement for any software project. I will talk about Python-based tools that make managing and running tests much easier and explore some statistics for projects hosted on GitHub that contain tests.

Entropy Based Genetic Association Tests and Gene-Gene Interaction Tests

PubMed Central

de Andrade, Mariza; Wang, Xin

2011-01-01

In the past few years, several entropy-based tests have been proposed for testing either single SNP association or gene-gene interaction. These tests are mainly based on Shannon entropy and have higher statistical power when compared to standard χ2 tests. In this paper, we extend some of these tests using a more generalized entropy definition, Rényi entropy, where Shannon entropy is a special case of order 1. The order λ (>0) of Rényi entropy weights the events (genotype/haplotype) according to their probabilities (frequencies). Higher λ places more emphasis on higher probability events while smaller λ (close to 0) tends to assign weights more equally. Thus, by properly choosing the λ, one can potentially increase the power of the tests or the p-value level of significance. We conducted simulation as well as real data analyses to assess the impact of the order λ and the performance of these generalized tests. The results showed that for dominant model the order 2 test was more powerful and for multiplicative model the order 1 or 2 had similar power. The analyses indicate that the choice of λ depends on the underlying genetic model and Shannon entropy is not necessarily the most powerful entropy measure for constructing genetic association or interaction tests.

A Boundary Scan Test Vehicle for Direct Chip Attach Testing

NASA Technical Reports Server (NTRS)

Parsons, Heather A.; DAgostino, Saverio; Arakaki, Genji

2000-01-01

To facilitate the new faster, better and cheaper spacecraft designs, smaller more mass efficient avionics and instruments are using higher density electronic packaging technologies such as direct chip attach (DCA). For space flight applications, these technologies need to have demonstrated reliability and reasonably well defined fabrication and assembly processes before they will be accepted as baseline designs in new missions. As electronics shrink in size, not only can repair be more difficult, but 49 probing" circuitry can be very risky and it becomes increasingly more difficult to identify the specific source of a problem. To test and monitor these new technologies, the Direct Chip Attach Task, under NASA's Electronic Parts and Packaging Program (NEPP), chose the test methodology of boundary scan testing. The boundary scan methodology was developed for interconnect integrity and functional testing at hard to access electrical nodes. With boundary scan testing, active devices are used and failures can be identified to the specific device and lead. This technology permits the incorporation of "built in test" into almost any circuit and thus gives detailed test access to the highly integrated electronic assemblies. This presentation will describe boundary scan, discuss the development of the boundary scan test vehicle for DCA and current plans for testing of direct chip attach configurations.

The test-retest reliability and criterion validity of a high-intensity, netball-specific circuit test: The Net-Test.

PubMed

Mungovan, Sean F; Peralta, Paula J; Gass, Gregory C; Scanlan, Aaron T

2018-04-12

To examine the test-retest reliability and criterion validity of a high-intensity, netball-specific fitness test. Repeated measures, within-subject design. Eighteen female netball players competing in an international competition completed a trial of the Net-Test, which consists of 14 timed netball-specific movements. Players also completed a series of netball-relevant criterion fitness tests. Ten players completed an additional Net-Test trial one week later to assess test-retest reliability using intraclass correlation coefficient (ICC), typical error of measurement (TEM), and coefficient of variation (CV). The typical error of estimate expressed as CV and Pearson correlations were calculated between each criterion test and Net-Test performance to assess criterion validity. Five movements during the Net-Test displayed moderate ICC (0.84-0.90) and two movements displayed high ICC (0.91-0.93). Seven movements and heart rate taken during the Net-Test held low CV (<5%) with values ranging from 1.7 to 9.5% across measures. Total time (41.63±2.05s) during the Net-Test possessed low CV and significant (p<0.05) correlations with 10m sprint time (1.98±0.12s; CV=4.4%, r=0.72), 20m sprint time (3.38±0.19s; CV=3.9%, r=0.79), 505 Change-of-Direction time (2.47±0.08s; CV=2.0%, r=0.80); and maximum oxygen uptake (46.59±2.58 mLkg -1 min -1 ; CV=4.5%, r=-0.66). The Net-Test possesses acceptable reliability for the assessment of netball fitness. Further, the high criterion validity for the Net-Test suggests a range of important netball-specific fitness elements are assessed in combination. Copyright © 2018 Sports Medicine Australia.

Propfan test assessment propfan propulsion system static test report

NASA Technical Reports Server (NTRS)

Orourke, D. M.

1987-01-01

The propfan test assessment (PTA) propulsion system successfully completed over 50 hours of extensive static ground tests, including a 36 hour endurance test. All major systems performed as expected, verifying that the large-scale 2.74 m diameter propfan, engine, gearbox, controls, subsystems, and flight instrumentation will be satisfactory with minor modifications for the upcoming PTA flight tests on the GII aircraft in early 1987. A test envelope was established for static ground operation to maintain propfan blade stresses within limits for propfan rotational speeds up to 105 percent and power levels up to 3880 kW. Transient tests verified stable, predictable response of engine power and propfan speed controls. Installed engine TSFC was better than expected, probably due to the excellent inlet performance coupled with the supercharging effect of the propfan. Near- and far-field noise spectra contained three dominant components, which were dependent on power, tip speed, and direction. The components were propfan blade tones, propfan random noise, and compressor/propfan interaction noise. No significant turbine noise or combustion noise was evident.

Testing enhances both encoding and retrieval for both tested and untested items.

Cho, Kit W; Neely, James H; Crocco, Stephanie; Vitrano, Deana

2017-07-01

In forward testing effects, taking a test enhances memory for subsequently studied material. These effects have been observed for previously studied and tested items, a potentially item-specific testing effect, and newly studied untested items, a purely generalized testing effect. We directly compared item-specific and generalized forward testing effects using procedures to separate testing benefits due to encoding versus retrieval. Participants studied two lists of Swahili-English word pairs, with the second study list containing "new" pairs intermixed with the previously studied "old" pairs. Participants completed a review phase in which they took a cued-recall test on only the "old" pairs or restudied them. In Experiments 1a, 1b, and 2, the review phase was given either before or after the second study list. Testing benefited memory to the same degree for both "new" and "old" pairs, suggesting that there were no pair-specific benefits of testing. The larger benefit from testing when review was given before rather than after the second study list suggests that the memory enhancement was due to both testing-enhanced encoding and testing-enhanced retrieval. To better equate generalized testing effects for "new" and "old" pairs, Experiment 3 intermixed them in the review phase. A statistically significant pair-specific testing effect for "old" items was now observed. Overall, these results show that forward testing effects are due to both testing-enhanced encoding and retrieval effects and that direct, pair-specific forward testing benefits are considerably smaller than indirect, generalized forward testing benefits.

Cell-free DNA testing after combined test: factors affecting the uptake.

2016-11-01

First, to assess what was the uptake of cell free DNA (cfDNA) testing after a combined test and the maternal and fetal factors that influenced this decision, and second, to assess the uptake and factors that influence the choice of invasive testing. This observational retrospective study included 1083 singleton pregnancies who had a combined test for screening for Down syndrome between 11 (+) (0) and 13 (+) (6) weeks. Multivariate logistic regression analysis was used to determine which factors affected the uptake of cfDNA test and invasive testing among risk for trisomies 21, 18, and 13, maternal characteristics and fetal nuchal translucency (NT) thickness. Two-hundred fifty-seven (23.7%) women had a cfDNA test, 89 (8.2%) had an invasive test, and 737 (68.1%) had no further test. The uptake of cfDNA increased with the risk for trisomies (p < 0.001), maternal age (p = 0.013), and was higher in nulliparous women (p = 0.004). The uptake of invasive test increased with the risk for trisomies (p < 0.001) and NT thickness (p < 0.001). This study shows that the uptake of cfDNA testing increases with the risk for trisomies, maternal age, and is higher in nulliparous, whereas the uptake of invasive testing increases with the risk for trisomies and NT thickness.

Modification of the Rappaport rapid test in large-scale testing for syphilis. Evaluation of the rapid plate and rapid card tests.

PubMed

Ghinsberg, R; Meir, E; Blumstein, G; Kafeman, R

1975-11-01

The Rappaport rapid (RR) plate and card tests were developed as modifications of the RR tube test to permit rapid and inexpensive screening of large numbers of subjects for the diagnosis of syphilis. More than 2,000 sera were examined in parallel by the Venereal Disease Research Laboratory (VDRL) slide test, the rapid plasma reagin (RPR) card test and the RR plate and card tests. There was complete agreement between the RR plate and card tests and the VDRL slide and RPR card tests in 96.6% of sera. In a selected group of 1,530 sera examined, in addition, by the fluorescent treponemal antibody absorption (FTA-ABS) test, there was agreement between the RR plate and card tests and the FTA-ABS test in 74.3% of sera and between the VDRL and RPR tests and the FTA-ABS test in 73.7% of sera. The RR plate test was found to be sufficiently sensitive and specific for the diagnosis of syphilis, although the VDRL slide test is perhaps more sensitive in primary and late latent syphilis. Since the antigen used in the RR tests is colored and stable and the sera do not require inactivation before the test, the tests are easier to perform than the VDRL slide test: the RR plate and card tests could therefore replace the VDRL test as a screening test, with hardly any loss of accuracy.

Stoker, C. J.; Bromley, L. K.

1985-01-01

Shuttle communications and tracking systems space to space and space to ground compatibility and performance evaluations are conducted in the NASA Johnson Space Center Electronics Systems Test Laboratory (ESTL). This evaluation is accomplished through systems verification/certification tests using orbiter communications hardware in conjunction with other shuttle communications and tracking external elements to evaluate end to end system compatibility and to verify/certify that overall system performance meets program requirements before manned flight usage. In this role, the ESTL serves as a multielement major ground test facility. The ESTL capability and program concept are discussed. The system test philosophy for the complex communications channels is described in terms of the major phases. Results of space to space and space to ground systems tests are presented. Several examples of the ESTL's unique capabilities to locate and help resolve potential problems are discussed in detail.
