以往的研究表明，低自尊个体对社会排斥信息表现出注意偏向。本研究采用事件相关电位（ERPs）技术，探讨了低自尊个体在高要求视觉检测任务中，与任务无关的拒绝线索是否能够捕获视觉空间注意。N2pc ERP成分作为空间注意分配的指标。结果表明，拒绝线索诱导更大的N2PC组件的反应与低水平的自尊比那些高水平的自尊的个人。这些结果表明，与任务无关的拒绝线索可能会吸引低自尊个体的注意力，而不是那些高自尊个体。这些研究结果提供了直接的电生理学支持的想法，即低水平的自尊的个人表现出的注意力偏差与社会排斥的线索。(C)2012爱思唯尔有限公司保留所有权利。
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.
