Identifying vulnerability to violence: The role of psychopathy and gender

Purpose – Recent research has suggested that a heightened sensitivity to nonverbal cues may give individuals with psychopathic traits an advantage when selecting potential victims. The purpose of this paper is to examine the effect of gender on the association between psychopathy and perceptions of vulnerability to violent victimization. Design/methodology/approach – A sample of 291 undergraduate students viewed a series of eight videos depicting individual female targets walking down a hallway from behind. Participants rated each target's vulnerability to violent victimization and provided a justification for each rating. In addition to these ratings, participants completed the Self-Report Psychopathy Scale. Findings – A series of hierarchical linear regressions revealed gender differences in the association between psychopathy and accuracy. Among male observers, total psychopathy scores, Factor 2 psychopathy scores, and scores on the antisocial behavior facet were positively associated with accuracy in perceiving vulnerability to violent victimization. Conversely, no associations were identified between psychopathy (total, Factors, and facets) and accuracy among female observers. This suggests that the adept ability to accurately perceive nonverbal cues signalling vulnerability is specific to males exhibiting psychopathic traits. Originality/value – The results of the current study highlight the importance of distinguishing male and female psychopathy in research and practice. Moreover, with an understanding of individual differences in the ability to accurately perceive nonverbal cues associated with vulnerability, we may begin to develop intervention strategies aimed at reducing future incidences of victimization

The Effect of Hypervigilance on the Relationship Between Sexual Victimization and Gait

Two studies investigated the relationship between hypervigilance, vulnerable gait cues, and a history of sexual victimization. In Study 1 (N = 130), gait was coded for traits relating to vulnerability where half of the sample was unaware of being videotaped (Unaware condition) and the other half was aware (Aware condition) to induce hypervigilance (between-subjects design). Gait was associated with a history of victimization, but only in the Unaware condition. A mediation analysis found that perceived impact of victimization mediated the association between victimization and vulnerable gait. In Study 2, female university students (N = 62) were measured on their victimization history and hypervigilance. Walking styles of participants were coded for the presence of vulnerability cues in both an Unaware and Aware condition (within-subjects design). A regression analysis revealed an association between hypervigilance and a reduced change in walking style between the two conditions. More notably, hypervigilance was found to moderate the relationship between sexual victimization and vulnerable gait but not violent victimization and vulnerable gait. These results suggest that hypervigilance may be an adaptive response that reduces perceived vulnerability in sexually victimized women
