Low self-esteem and the neural basis of attentional bias for social rejection cues: Evidence from the N2pc ERP component

Previous studies have indicated that individuals with low self-esteem show an attentional bias toward information concerning social rejection. The present study used event-related potentials (ERPs) to investigate whether task-irrelevant rejection cues could capture the visuo-spatial attention of low self-esteem individuals during a demanding visual detection task. The N2pc ERP component was measured as an index of the allocation of spatial attention. Results revealed that rejection cues induced greater N2pc component responses among individuals with low levels of self-esteem than for those with high levels of self-esteem. These results suggest that task-irrelevant rejection cues are likely to capture the attention of individuals with low self-esteem but not those with high self-esteem. These findings provide direct electrophysiological support for the idea that individuals with low levels of self-esteem show an attentional bias for cues related to social rejection.

► Used ERPs to investigate whether rejection could capture the attention of low self-esteem.
► N2pc ERP component was measured as an index of the allocation of spatial attention.
► Rejection cues induced greater N2pc ERP responses among individuals with low self-esteem.
