Self-report measures of child and adolescent psychopathy as predictors of offending in four samples of justice-involved youth

The authors examined the relation between self-report psychopathy measures and official records of offending in four samples of justice-involved youth (total N = 447). Psychopathy measures included the Antisocial Process Screening Device (APSD) and a modified version of the Childhood Psychopathy Scale (mCPS). Measures of offending included the total number of preadmission arrest charges for three samples (n = 392) and the total number of offenses in the year following release for two samples (n = 138). Neither measure was a strong correlate of preadmission offenses. Although mCPS scores were associated with postrelease offending in one sample, effects for the APSD were observed only when reoffending was conceptualized as a dichotomous variable, indicating a lack of robustness in this association. The findings suggest caution in the use of self-report measures of psychopathic features for decision making with respect to issues of delinquency risk among justice-involved youth.     

Think Women, Think Warm: Stereotype Content Activation in Women with a Salient Gender Identity, Using a Modified Stroop Task

We examined whether a salient gender identity activates gender stereotypes along the dimensions of sociability and ability (Fiske et al. 2002). A sample of US undergraduates (40 men, 38 women) instructed to think about women subsequently took longer to name the colors of words associated with sociability than ability on a modified Stroop task. Solo women in another sample of US undergraduates (45 women) showed the same response pattern. Women in a third sample of US adults (20 men, 16 women) showed a similar pattern. Meta-analysis of the three samples suggests women with a salient gender identity experience relative activation of only the positive dimension of a stereotype (e.g. “woman” equals warm).     

Estimates of the Validity and Utility of the Conners’ Continuous Performance Test in the Assessment of Inattentive and/or Hyperactive-Impulsive Behaviors in Children

This study evaluated the validity and classification utility of the Conners' Continuous Performance Test (CCPT) in the assessment of inattentive and hyperactive-impulsive behaviors in children. Significant, positive correlations between the CCPT parameters and behavioral ratings of ADHD behaviors were hypothesized. In addition, it was hypothesized that the CCPT parameters would perform better than a random test (chance) and show fair to moderate utility of classification across the different indices. Participants were 104 children between 6 and 12 years of age who were referred for evaluation of attention problems. The first hypothesis was not supported. There were no significant, positive correlations between the CCPT parameters and parent and teacher ratings of inattentive and hyperactive-impulsive behaviors. The second hypothesis was only partially supported. The CCPT Overall Index and the Omission Errors (84th percentile cutoff) performed better than a random test; however, the utility of the CCPT Overall Index only ranged from poor to slight. Receiver operating characteristic analyses showed the accuracy of the CCPT to be low. The implications and limitations of this study and future research directions are discussed.     

Vocal and gestural responses of cross-fostered chimpanzees

Ten positive, five neutral, and five negative events were presented to two chimpanzees, Tatu (female, 64 months old) and Dar (male, 56 months old), who had been cross-fostered from birth by human beings. Each event was announced in American Sign Language 10 s before. The announcements and events were common items in the cross-fostering routines and were administered according to a balanced design over a period of 2 months. Vocal and signed responses to the announcements and to the events were recorded. The likelihood of either mode of response depended on affective charge, and the likelihood of vocal and signed responses was positively correlated. Signed responses were more likely than vocal responses; signed responses were more likely to be evoked by announcements than by events, whereas vocal responses were more likely to be evoked by events than by announcements. The type of vocal response depended on the affective charge and on whether the response was immediate (to the event) or anticipatory (to the announcement). Incorporation of signs and phrases from the announcements, and reiteration of signs and phrases within an utterance depended on affective charge, just as they do for human children.     

Sensitivity to conversational deviance in right-hemisphere-damaged patients.

To participate meaningfully in conversation, speakers must be sensitive to statements which advance and those which block the direction of a discourse. The effect of right-hemisphere damage (RHD) on sensitivity to conversational advancers and blockers was investigated by asking subjects to interpret normal conversations and conversations which were blocked by violations of Gricean maxims: specifically, tangential and redundant statements. Results indicate that RHD patients function normally in canonical, directed conversation. However, they have difficulty interpreting and judging the effect of blocking statements, particularly with regard to tangentiality. The results are discussed in terms of a mental model of directed conversation which incorporates both structural and affective components.     

Somatization tendencies and ability to detect internal body cues

39 subjects performed a task in which they were required to detect the presence of a resistive load during the inhalation phase of breathing. Subjects were also measured on somatization tendencies, using the SCL-90-R test. A signal-detection analysis indicated an inverse relationship between ability to detect the resistive load during breathing and somatization score. Results are discussed relative to possible ramifications for somatoform disorders.     

Factor analyses of two 'attitude toward gender role' questionnaire

Two questionnaires which purport to assess attitudes toward gender role, the Maferr Inventory of Feminine Values and the Sex Stereotype Questionnaire, were submitted to a factor analysis. While each analysis of the five response set items yielded interpretable factors with unequivocal item scores, the obtained factors are not consistent with the a priori assignment of items to "groupings" suggested by the manuals for these instruments. The implications of using questionnaires with questionable psychometric properties is discussed.     

Table of criterion values (β) used in signal detection theory

A table of criterion values for use with the theory of signal detection (TSD) is presented. Criterion values (β) are presented for varying proportions of hits and false alarms. A brief explanation of signal detection theory is given, and the measures for sensory sensitivity (d′) and response criterion (β) are described.
