Psychopathy and gaze cueing.

BACKGROUND AND OBJECTIVES: Psychopathic traits - and especially callous affective features - have been linked to altered processing of others' emotional expressions, and to reduced attention to the eyes. Despite the importance of gaze cueing (i.e., the tendency to orient attention toward where someone else is looking) for social functioning, few studies have investigated relationships between psychopathic traits and gaze cueing, and whether facial emotional expression influence these relationships, obtaining mixed results. To address this gap, the present study aimed to evaluate associations between psychopathic traits and gaze cueing for emotional and neutral expressions. METHODS: 65 non-clinical male participants (Mage = 27.3 years) completed two self-report measures of psychopathy and performed laboratory tasks to assess gaze-cueing for emotional vs. neutral faces and an arrow-cueing task as a comparison. RESULTS: Linear mixed models showed no significant associations of emotional (versus neutral) expressions, or psychopathy trait dimensions, with either gaze cueing or arrow cueing. LIMITATIONS: Reliance on a convenience sample of non-clinical men, assessed with self-reports measures of psychopathy, and using static emotional stimuli limit the generalizability of our findings. CONCLUSIONS: Findings suggest that psychopathic traits are not associated with individual differences in following others' gaze to direct attention, and that there was no advantage for affective relative to neutral expressions.

Implicit vs. explicit dimensions of guilt and dominance in criminal psychopathy.

The current study investigated the relationship between psychopathy and two concepts that hold a central position in conceptualizations of this disorder, being guilt and dominance. Both constructs were measured using explicit measures (i.e., self-report), as well as indirect assessment (i.e., the Single Category Implicit Association Test; Sc-IAT). Our sample consisted of 43 psychopathic offenders, 42 nonpsychopathic offenders, and 26 nonoffender controls. Although no overall group differences emerged, the lifestyle/antisocial traits of psychopathy (Factor 2) predicted reduced self-reported guilt on a dimensional level. As hypothesized, such a relationship was absent for the interpersonal/affective dimension of psychopathy (Factor 1). Psychopathy was unrelated to implicit self-guilt associations. Regarding dominance, psychopathy was not significantly associated with indirectly or explicitly assessed dominance. These findings are interpreted in the light of empirical knowledge on moral emotions, insight and response distortion in highly antisocial offenders.

The Mask of Sanity: Facial Expressive, Self-Reported, and Physiological Consequences of Emotion Regulation in Psychopathic Offenders.

This study investigated the physiological, self-reported, and facial correlates of emotion regulation in psychopathy. Specifically, we compared psychopathic offenders (n = 42), nonpsychopathic offenders (n = 42), and nonoffender controls (n = 26) in their ability to inhibit and express emotion while watching affective films (fear, happy, and sad). Results showed that all participants were capable of drastically diminishing facial emotions under inhibition instructions. Contrary to expectation, psychopaths were not superior in adopting such a "poker face." Further, the inhibition of emotion was associated with cardiovascular changes, an effect that was also not dependent on psychopathy (or its factors), suggesting emotion inhibition to be an effortful process in psychopaths as well. Interestingly, psychopathic offenders did not differ from nonpsychopaths in the capacity to show content-appropriate facial emotions during the expression condition. Taken together, these data challenge the view that psychopathy is associated with either superior emotional inhibitory capacities or a generalized impairment in showing facial affect.

Theory of Mind, Social Desirability, and Unlikely Symptom Reporting in Offenders With and Without Psychopathy.

The current study investigated the relationship between psychopathy and theory of mind (ToM), by comparing the performance of nonpsychopathic offenders (n = 40), psychopathic offenders (n = 42), and nonoffender controls (n = 26) on Happé's test of ToM (Happé, 1994). In addition, we investigated whether offenders' ToM skills would moderate the association between the antisocial psychopathy component (Factor 2) and self-presentation (i.e., the tendency to report social desirability and unlikely symptoms). Results showed groups did not differ in ToM performance. As expected though, ToM moderated the association between psychopathy and self-presentation: only for offenders relatively high in ToM, Factor 2 was strongly related to less social desirability and more unlikely symptom reporting. These results could indicate that offenders who are high in both ToM and Factor 2 exaggerate their mental dysfunction to express their need for clinical attention. Results are used to critically evaluate the interpretation of occurrences in which offenders overplay their psychopathology.

Antisocial features and "faking bad": A critical note.

We critically review the literature on antisocial personality features and symptom fabrication (i.e., faking bad; e.g., malingering). A widespread assumption is that these constructs are intimately related. Some studies have, indeed, found that antisocial individuals score higher on instruments detecting faking bad, but others have been unable to replicate this pattern. In addition, studies exploring whether antisocial individuals are especially talented in faking bad have generally come up with null results. The notion of an intrinsic link between antisocial features and faking bad is difficult to test and research in this domain is sensitive to selection bias. We argue that research on faking bad would profit from further theoretical articulation. One topic that deserves scrutiny is how antisocial features affect the cognitive dissonance typically induced by faking bad. We illustrate our points with preliminary data and discuss their implications.

Examining the influence of psychopathy, hostility biases, and automatic processing on criminal offenders' Theory of Mind.

Theory of Mind (ToM) is a social perceptual skill that refers to the ability to take someone else's perspective and infer what others think. The current study examined the effect of potential hostility biases, as well as controlled (slow) versus automatic (fast) processing on ToM performance in psychopathy. ToM abilities (as assessed with the Reading the Mind in the Eyes Test; RMET; Baron-Cohen, Wheelwright, Hill, Raste, & Plumb, 2001), was compared between 39 PCL-R diagnosed psychopathic offenders, 37 non-psychopathic offenders, and 26 nonoffender controls. Contrary to our hypothesis, psychopathic individuals presented with intact overall RMET performance when restrictions were imposed on how long task stimuli could be processed. In addition, psychopaths did not over-ascribe hostility to task stimuli (i.e., lack of hostility bias). However, there was a significant three-way interaction between hostility, processing speed, and psychopathy: when there was no time limit on stimulus presentation, psychopathic offenders made fewer errors in identifying more hostile eye stimuli compared to nonoffender controls, who seemed to be less accurate in detecting hostility. Psychopaths' more realistic appraisal of others' malevolent mental states is discussed in the light of theories that stress its potential adaptive function.

Brief communication: investigating the relationship between psychopathy and interoceptive awareness.

Psychopathy is a disorder that is characterized by marked emotional deficiencies. Because previous studies suggest that an individual's sensitivity to bodily signals--or "interoceptive awareness"--is associated with various components of emotional functioning, the authors expected this capacity to be reduced in psychopathic individuals. Therefore, the current study examined the relationship between psychopathy and interoceptive awareness by assessing heartbeat detection abilities in a group of 75 male personality disordered offenders, varying in their degree of psychopathy, as assessed with the Hare Psychopathy Checklist-Revised (PCL-R; Hare, 2003). Regression analyses revealed that PCL-R Facet 4, which reflects antisocial behavior, was predictive of reduced interoceptive awareness. These findings suggest that the expression of psychopathic behavior might be influenced by an attenuated sensitivity to one's own bodily signals.
