Previous findings are generally consistent with the notion that individuals with low self-esteem tends to easily orient their attention on negative stimuli. The main objective of the present study was to further investigate the time course of attention deployment to positive (happy) and negative (angry) facial expressions in visual probe task using event-related potentials (ERP) technology in 15 high versus 15 low self-esteem participants while they viewed pairs of faces (e.g., happy face paired with neutral face or angry face paired with neutral face) shown for 500 ms and followed by a probe. Behavioral results showed that individuals with low self-esteem simply had faster manual reaction times on the entire task. ERP results showed that individuals with low self-esteem, but not high self-esteem, displayed increased P1 and N1 activity to both happy and angry facial expression. These findings suggest that emotional stimuli (angry faces and happy faces) elicited greater mobilization of attentional resources in individuals with low self-esteem.
先前的研究结果普遍与以下观点一致，即自尊心较低的个体往往容易将注意力集中在负面刺激上。本研究的主要目的是进一步使用事件相关电位 (ERP) 技术，在 15 名高自尊者和 15 名低自尊者中，调查在视觉探测任务中，积极（快乐）和消极（愤怒）面部表情的注意分配的时间进程，当他们观看每对持续 500 毫秒的面部（例如，快乐脸与中性脸配对或愤怒脸与中性脸配对），然后出现探测。行为结果表明，低自尊者在整个任务中反应更快。ERP 结果表明，低自尊者而非高自尊者对快乐和愤怒的面部表情表现出 P1 和 N1 活动增加。这些发现表明，情绪刺激（愤怒的面孔和快乐的面孔）在低自尊者中引起了更多的注意力资源的调动。
