In the I of the beholder: an attempt to capture the implicit self-concept regarding psychopathy

This article explores the implicit self-concept pertaining to psychopathy. Two online studies showed inconsistent results, with Study 1 (n = 243) suggesting that psychopathy is linked to an implicit self-concept marked by low empathy and Study 2 (n = 230) implying no such relationship. In a sample of offenders and community controls (Study 3a, n = 166), higher scores on the Psychopathy Checklist-Revised (PCL-R) were related to an implicit self-concept of being less rather than more antisocial, and the implicit self-concept showed incremental validity compared to the explicit self-concept. The retesting of an offender subsample (Study 3b, n = 47) yielded no evidence for temporal stability or convergent validity. The implicit self-concept of highly psychopathic individuals thus appears to vary, depending on the social context. Future studies should replicate these results in different samples, using additional external correlates.

Rational, emotional, or both? Subcomponents of psychopathy predict opposing moral decisions

Recent research has documented a small but significant correlation between psychopathic capacities and utilitarian moral judgment, although the findings are generally inconsistent and unclear. We propose that one way to make sense of mixed findings is to consider variation in perspective-taking capacities of psychopathic individuals. With this in mind, we had criminal offenders (n = 60), who varied in their psychopathy levels according to the Psychopathy Checklist-Revised (PCL-R), respond to common sacrificial moral dilemmas (e.g., trolley dilemmas) under different conditions. In a baseline condition, participants simply responded to the sacrificial moral dilemmas as is typically done in previous research. In an "emotion-salient" condition, participants had to reason about the emotions of another person after solving moral dilemmas (deliberative processing). In the "emotion-ambiguous" condition, participants saw images of people in distress, after solving moral dilemmas, but did not have to explicitly reason about such emotions (spontaneous processing). The four PCL-R facets predicted distinct interference effects depending on spontaneous versus deliberative processing of hypothetical victim's emotions. The findings suggest that the use of a multi-faceted approach to account for cognitive and moral correlates of psychopathy may help address previously mixed results. Implications and future directions for theory and research are discussed.

Use of the Psychopathy Checklist-Revised in Legal Contexts: Validity, Reliability, Admissibility, and Evidentiary Issues

The construct of psychopathy has received considerable attention from clinicians, researchers, and legal practitioners because of its demonstrated association with a range of outcomes of interest to the criminal justice system. The Psychopathy Checklist-Revised (PCL-R) is generally regarded as the premier assessment tool for measuring psychopathy in correctional and legal contexts, and the PCL-R is being used with increased frequency to address a variety of legal questions. This article provides a comprehensive examination and review of the PCL-R's use in legal contexts. We begin by reviewing various uses (appropriate and inappropriate) of the PCL-R in legal contexts, using the risk-need-responsivity (RNR) model as the conceptual framework. After reviewing available data regarding the use of the PCL-R in legal contexts, we review and synthesize psychometric research with psycholegal relevance, with a focus on the PCL-R's construct validity, predictive validity, and interrater reliability. We then discuss the scientific acceptability and clinical utility of the PCL-R's structural, predictive, and measurement properties for credibility in court, followed by sample cross-examination questions. We conclude with a review of admissibility issues relating to the use of the PCL-R in various legal proceedings.

Detection of Psychopathic Traits in Emotional Faces

When meeting someone at zero acquaintance, we make assumptions about each other that encompass emotional states, personality traits, and even cognitive abilities. Evidence suggests individuals can accurately detect psychopathic personality traits in strangers based on short video clips or photographs of faces. We present an in-depth examination of this ability. In two studies, we investigated whether high psychopathy traits are perceivable and whether other traits affect ratings of psychopathic traits in the sense of a halo effect. On the perceiver's end, we additionally examined how cognitive abilities and personality traits of the responders affect these ratings. In two studies (n1 = 170 community adults from the USA, n2 = 126 students from Australia), participants rated several targets on several characteristics of psychopathy, as well as on attractiveness, masculinity, sympathy, trustworthiness, neuroticism, intelligence, and extraversion. Results show that responders were generally able to detect psychopathy. Responders generally came to a consensus in their ratings, and using profile similarity metrics, we found a weak relation between ratings of psychopathy and the targets' psychopathy level as determined by the Psychopathy Checklist: Short Version. Trait ratings, though, were influenced by the ratings of other traits like attractiveness. Finally, we found accuracy in the perception of psychopathy was positively related to fluid intelligence but unrelated to emotion perception ability.
