| description | Abstract Objective Disaster scenes produce long‐term negative feelings in those who experience them. Previous studies have focused on mitigating disaster impacts through directed forgetting or conscious suppression. However, the initial emotional processing of disaster scenes is not fully understood, hindering the comprehension of long‐term disaster impacts. This study aims to investigate how pictures of disaster scenes evoking disgust and sadness are processed via cortical electrical activity. Methods Pictures of grief and mutilation from disasters were used to evoke sadness and disgust, respectively. Event‐related desynchronization (ERD) and event‐related potentials (ERPs) were used to quantify the intensity and time‐course of emotional processing. Results The information processing of emotional pictures was stronger than neutral pictures, represented by greater declines of alpha ERD. In the posterior ERP components of N1 and EPN, amplitudes for emotional pictures were larger than those for neutral pictures, which reflected the effects of arousal on visual perception. In the anterior ERP components of P2, P3, and LPP, disgust pictures showed higher attention attraction and enhanced encoding memory processing. Conclusions Disgust disaster scenarios induced long‐term prominent LPP, which may correspond with the long‐term negative impacts of the disaster. |
