An event-related potentials study on the attention function of posttraumatic stress disorder.

Year: 2015

Type: article

Abstract: OBJECTIVE: In order to examine the functional defects and attentional bias in post-traumatic stress disorder (PTSD) patients, event-related potentials (ERP) of attention was investigated. METHODS: Three groups of emotion pictures, positive, negative (or violent) and neutral, were viewed by 19 PTSD patients and 15 normal controls. Each picture had a frame, and participants reacted to the color of the frame by clicking buttons. Electroencephalogram (EEG) and behavior data were recorded. Peak latencies and amplitudes of P2 were measured. RESULTS: For the three groups of pictures, PTSD patients had longer reaction time than the controls. Significant difference was found between PTSD patients and controls in response to violent, positive and neutral pictures.
