Hands Up! Atypical Defensive Reactions in Heavy Players of Violent Video Games When Exposed to Gun-Attack Pictures.

摘要: Threatening cues and surrounding contexts trigger specific defensive response patterns. Posturography, a technique for measuring postural strategies, has been used to evaluate motor reactions in humans. When exposed gun pointed pictures, humans were shown exhibit an immobility reaction. Short long-term exposure violent video games was be causal risk factor increased aggressive behavior. Assaultive violence with is major reactions, post-traumatic stress disorder (PTSD) the most characteristic psychiatric sequelae. Recent studies point links between PTSD symptoms emotional shortfalls non-clinical trauma-exposed samples. The present study investigated threat heavy players of compared non-players. Male university students screened according use divided three groups: non-players, moderate players, players. Stimuli pictures depicting man pointing directed at participant. In matched control non-lethal objects replaced gun. Posturography recorded assessed. non-players exhibited expected reduction amplitude body sway (immobility), presented atypical augmented sway, showed intermediate reactivity. Heavy significant distinct reaction They also scored significantly higher than Disadvantageous vulnerability symptoms, revealed study, add other shortcomings
