abstract="This study aimed to identify the neural correlates of aggression-related attentional selectivity to angry faces in physical aggression. Physical aggression in a non-clinical sample of young men (N = 35) was measured using an aggression questionnaire. Visual attentional bias to angry faces was assessed using a dot-probe task during which angry and neutral faces were presented simultaneously, and EEG was recorded. Median split and correlational analyses were conducted to assess the relationship between physical aggression and attentional bias. Behavioural results indicated that higher levels of physical aggression were associated with greater attentional bias to angry faces. ERP results revealed an interaction where males with higher physical aggression had undifferentiated P300 amplitudes to angry and neutral trials, whereas low physical aggression males exhibited greater P300 amplitude to angry than to neutral trials. Increased levels of physical aggression were significantly related to increased P300 amplitude on neutral trials only. It was concluded that the aggressive males selectively attend to angry faces, and that attentional bias is characterized by undifferentiating P300 amplitude. We propose that this results from an inferior ability to downregulate competing angry face distractors when responding to probes replacing neutral faces. These findings indicate that attentional bias to angry faces in individuals with higher physical aggression is characterized by a distinctive ERP signature, which could help inform the development of therapeutic interventions seeking to reduce aggression.<br><br>Copyright © 2018.
