Self-monitoring refers to the extent to which people regulate their self-presentation by tailoring their behaviors to social situations. To examine the psychophysiological correlates of self-monitoring, we measured heart rate, skin conductance level, and EEG alpha of the frontal and parietal scalp regions during baseline and while anticipating an impromptu speech task. High self-monitors showed lower cortical activity in the frontal and parietal scalp regions than low self-monitors. Furthermore, self-monitoring scores were negatively correlated with skin conductance level when anticipating social threat. Social anxiety and depression did not account for these results. The findings suggest that high self-monitors show lower autonomic and cortical arousal than low self-monitors when anticipating social stress.
自我监控是指人们根据社交情境调整自身行为来规范自我表现的程度。为了研究自我监控的心理生理相关性,我们在基线状态以及预期进行即席演讲任务时,测量了心率、皮肤电导率水平以及额叶和顶叶头皮区域的脑电图α波。高自我监控者在额叶和顶叶头皮区域的皮层活动低于低自我监控者。此外,在预期社交威胁时,自我监控得分与皮肤电导率水平呈负相关。社交焦虑和抑郁并不能解释这些结果。研究结果表明,在预期社交压力时,高自我监控者比低自我监控者表现出更低的自主神经和皮层唤醒水平。
