However, conflicting evidence suggests that anxiety may be positively correlated with some aspects of the psychopathy construct. This position may seem somewhat paradoxical when considered alongside impaired processing of fear related stimuli in psychopathic personality. The aim of the current paper was to examine the distinct relations of callous, egocentric, and antisocial psychopathic traits with measures of anxiety and social anxiety in samples of non-offenders (Study 1) and violent offenders (Study 2). In Study 2 we also used an emotion recognition task to examine fearful face recognition. In Studies 1 and 2 we showed distinct and opposite significant relationships of egocentric and antisocial psychopathic traits with trait anxiety. Thus, while trait anxiety was negatively predicted by egocentric traits, it was predicted in a positive direction by antisocial traits in both samples. In Study 2 we found that callous traits were predictive of greater impairments in fearful face recognition. These findings suggest that anxiety and fear are distinguishable constructs in relation to psychopathic personality traits, and are discussed in terms of potentially separable mechanisms for these two constructs.

However, the extent to which similar problems can be observed among sexual offenders remains unknown. Using a computerized task, we presented sexual and violent offenders, and non-offenders, with male and female expressions of anger, disgust, fear, happiness, sadness, and surprise, morphed with neutral expressions at varying levels of intensity (10, 55, and 90% expressive). Based on signal detection theory, we used hit rates and false alarms to calculate the sensitivity index d-prime (d') and criterion (c) for each emotional expression. Overall, sexual offenders showed reduced sensitivity to emotional expressions across intensity, sex, and type of expression, compared with non-offenders, while both sexual and violent offenders showed particular reduced sensitivity to fearful expressions. We also observed specific effects for high (90%) intensity female faces, with sexual offenders showing reduced sensitivity to anger compared with non-offenders and violent offenders, and reduced sensitivity to disgust compared with non-offenders. Furthermore, both sexual and violent offenders showed impaired sensitivity to high intensity female fearful expressions compared with non-offenders. Violent offenders also showed a higher criterion for classifying moderate and high intensity male expressions as fearful, indicative of a more conservative response style, compared with angry, happy, or sad. These results suggest that both types of offender show problems in emotion recognition, and may have implications for understanding the inhibition of violent and sexually violent behaviors.

These impairments may, in part, reflect reduced attention to the eyes of emotional faces. Although reduced attention to the eyes has been noted among children with conduct problems and callous-unemotional traits, similar findings are yet to be found in relation to psychopathic traits among adult male participants. Here we investigated the relationship of primary (selfish, uncaring) and secondary (impulsive, antisocial) psychopathic traits with attention to the eyes among adult male non-offenders during an emotion recognition task. We measured the number of fixations, and overall dwell time, on the eyes, and the mouth of male and female faces showing the six basic emotions at varying levels of intensity. We found no relationship of primary or secondary psychopathic traits with recognition accuracy. However, primary psychopathic traits were associated with a reduced number of fixations, and low...

However, evidence suggests that nonschizophrenic psychopaths match or even outperform healthy controls on tests of metacognition. We hypothesize that the metacognitive difficulties associated with schizophrenia may be ameliorated by comorbid psychopathy. To this end, metacognition (using the Metacognition Assessment Scale-Abbreviated [MAS-A]) and psychopathy (using the Hare Psychopathy Checklist-Revised [PCL-R]) are assessed in 79 patients with schizophrenia with a history of criminal offending. Piecewise regression reveals that the association between metacognition and psychopathy changes from a negative to a positive association at a breakpoint corresponding to a score of 24 on the PCL-R. This score is within the range of the cut-off point used for the diagnosis of psychopathy in Europe, which corresponds to a score of 26 on the PCL-R. The patients scoring above 24 on ...

This may manifest as a reduced ability to inhibit prepotent race biase responses. Here, we tested the effects of acute alcohol consumption, and elevated anti social psychopathic traits, on judgments of the attractiveness and health of ethnic ingrou and outgroup faces. In the first study, we show that following acute alcohol consumption at a dose that is sufficient to result in impaired performance on tests of executive function Caucasian participants judged White faces to be more attractive and healthier compared t when sober. However, this effect did not extend to Black faces. A similar effect was foun in a second study involving sober Caucasian participants where secondary psychopathi traits were related to an intergroup bias in the ratings of attractiveness for White versu Black faces. These results are discussed in terms of a model which postulates that poo prefrontal functioning leads to increases in ingroup liking as a result of impaired abilitie for prepotent response inhibition. d t d p , , o d c s r s

The aim of this study was to compare solo (n = 20) and co- (n = 20) female sexual offenders on a variety of clinical characteristics. It was found that although solo and co-offenders reported similar developmental experiences and psychological dispositions, differences were found in environmental niche, offense preceding, and positive factors. Specifically, solo offenders demonstrated a greater presence of personal vulnerabilities including mental health and substance abuse difficulties. Co-offenders reported a greater presence of environmentally based factors, including a current partner who was a known sex offender and involvement with antisocial peers. It is suggested that these results have implications for understanding assessment and intervention needs for these groups of sexu...

Deficits in emotional regulation are particularly pertinent in sexual offenders. Therefore, therapeutic programs should, in part, focus on the development of effective strategies for the control of emotional arousal. In this review, we will provide an outline of how anatomical structures including the amygdala and regions of the prefrontal cortex (PFC) are involved in the appropriate regulation of emotion. It is argued in this paper that the effective control of emotional states may be helped through the adoption of a group of meditational practices, known as mindfulness techniques, which have emerged from Buddhist philosophy. These techniques involve slow, deep breathing and have been shown to affect vagal modulation of the heart and the functioning of specific neural circuits which are critically involved in emotional regulation.
