Intact prioritization of fearful faces during continuous flash suppression in psychopathy

Affective state recognition and in particular the identification of fear is known to be impaired in psychopathy. It is unclear, however, whether this reflects a deficit in basic perception (‘fear blindness’) or a deficit in later cognitive processing. To test for a perceptual deficit, 63 male incarcerated offenders, assessed with the Hare Psychopathy Checklist-Revised (PCL-R), and 59 age-matched control participants detected fearful, neutral, and happy facial expressions rendered invisible through continuous flash suppression (CFS), a strong interocular suppression technique. Consistent with previous CFS studies on children, student and community samples, fearful faces were detected faster than neutral faces, which were detected faster than happy faces. Detection of emotional faces was unimpaired in offenders, with strong evidence for a full-blown fear advantage. Moreover, the fear advantage was not reduced in the 20 offenders qualifying as psychopaths according to the PCL-R, and there was no correlation between the fear advantage and PCL-R scores in the 63 incarcerated offenders. These results show that basic visual detection of fearful faces is unimpaired in psychopathy. Deficits in the processing of fearful facial expressions in psychopathy may thus not reflect fear blindness, but impairments at later post-perceptual processing stages related to attention, memory, decision-making, or language.

Construct Validity of the German Version of the Hare Psychopathy Checklist – Revised

The Hare Psychopathy Checklist – Revised (PCL-R) is among the most well-established instruments for the assessment of psychopathy. The PCL-R is a 20-item observer rating instrument based on file review and a semi-structured interview. The current study aimed to investigate the validity of the German adaptation of the PCL-R, its factor structure, construct validity, and association with socially desirable responding in a sample of male offenders ( N = 118). A parcel model with four facets and two factors yielded excellent model fit. Convergent and discriminant validity were assessed based on correlational analyses, a multitrait-multimethod (MTMM) matrix, and a canonical correlation analysis (CCA) including measures of psychopathy, antisocial personality disorder (ASPD), global personality dimensions, alexithymia, and impulsivity. The MTMM matrix as well as substantial associations with self-reported psychopathic traits and observer ratings of ASPD indicated convergent validity. Correlational analyses revealed that Factor 1 of the PCL-R was associated with low neuroticism, whereas Factor 2 was associated with impulsivity as well as with low agreeableness and conscientiousness. The PCL-R total score and Factor 2 were negatively correlated with impression management. Overall, the current findings support the validity of the German adaptation of the PCL-R.
