This entry explores how nonverbal cues like gait serve as indicators of vulnerability and influence potential victim selection in the context of assault and sexual violence. Research demonstrates that many individuals, especially those with psychopathic traits, are adept at identifying non-verbal cues that may communicate vulnerability to assault. Seminal studies reveal that disjointed, asymmetrical, or atypical walking styles are more likely to be perceived as vulnerable. Moreover, psychopathy has been linked to heightened attunement to these cues, suggesting specialized sensitivity to non-verbal cues of weakness, submissiveness, and victimization history. Additionally, research indicates that a person’s history of victimization may manifest in their gait, and that hypervigilance can mitigate non-verbal indicators of vulnerability when individuals consciously alter their movements. Evidence also supports the effectiveness of training interventions in reducing gait-based vulnerability cues. Taken together, these findings highlight gait as a significant socio-communicative behavior with implications for victimology, psychology, and violence prevention strategies.
