“…The Child and Adolescent Taxon Scale (CATS; Harris, Rice, & Quinsey, 1994;Quinsey, Harris, Rice, & Cormier, 2006) is an actuarial rating scale developed from variables related to childhood and adolescent antisocial and aggressive characteristics (e.g., childhood aggression problem, arrested below the age of 16). This scale has eight items scored either 0 (No) or 1 (Yes).…”

The objective of the present study was to compare incarcerated male and female juvenile offenders regarding psychopathic traits, behavior problems, psychopathy taxon, conduct disorder, self-reported delinquent behavior, and crime seriousness. Within a total forensic sample of 261 detainee participants, subdivided in a male group (n= 217) and a female group (n= 44), statistically significant differences were found. Female juvenile offenders show less callous-unemotional traits, more emotional symptoms, more prosocial behaviors, less self-reported delinquent behavior, and lower crime seriousness. Conduct disorder prevalence was very high, but no statistically significant gender differences were found. The predictive importance of psychopathic traits, behavior problems, psychopathy taxon, and conduct disorder for the prediction of group membership (female versus male) was established by binary logistic regression.

“…15 The two groups did not differ in age, gender, ethnicity, handedness, or substance dependence. 12 This cutoff was chosen to be consistent with our previous research on this sample, 9,12,15 and is similar to the optimal cutoff suggested by taxometric analyses of the PCL-R. 16 Full informed, written consent was obtained from all subjects in accordance with Institutional Review Board procedures at University of Southern California. 12 …”

Abnormal Structural Correlates of Response Perseveration in Individuals With Psychopathy

Structural deficits in the frontotemporal network have been shown in individuals with psychopathy and are posited to contribute to neuropsychological impairments such as response perseveration. However, no study to date has examined structural correlates of response perseveration in individuals with psychopathy. In this structural MRI study, the authors found higher correlations between increased response perseveration and reduced cortical thickness in the orbitofrontal and anterior temporal regions in individuals with psychopathy than in healthy-comparison subjects. The findings provide preliminary evidence suggesting potential contributions of frontotemporal structural deficits in neurocognitive impairment with perseveration in individuals with psychopathy.

“…The Childhood and Adolescent Taxon Scale self-report version (CAT-SR; Seto et al 1997) consists of eight items that measure early behavioral problems associated with adult psychopathy (Harris, Rice, and Quinsey 1994). Each of the eight items is scored as absent (0), some indication (1), or present (2), and an average of the eight items is taken.…”

Do people differentially remember cheaters?

The evolution of reciprocal altruism probably involved the evolution of mechanisms to detect cheating and remember cheaters. In a well-known study, Mealey, Daood, and Krage (1996) observed that participants had enhanced memory for faces that had previously been associated with descriptions of acts of cheating. There were, however, problems with the descriptions that were used in that study. We sought to replicate and extend the findings of Mealey and colleagues by using more controlled descriptions and by examining the possibility of enhanced altruist recognition. We also examined whether individual differences in cheating tendencies were related to cheater and altruist recognition. In the first experiment, 164 undergraduates saw 40 faces that were paired with character descriptions representing the categories cheating, trustworthiness, altruism, or neutral, for individuals who had either low or high social status. One week later participants reported which faces they recognized from the previous week (among 80 faces). Overall, the results failed to replicate the findings of Mealey and her colleagues, as there was no enhanced memory for cheaters. In addition, there was no enhanced memory for altruists, and no effect of participants' cheating tendencies. A second experiment using a slightly different methodology produced similar results, with some evidence for enhanced memory for altruists.
