Abstract: To examine gender characteristics and neural mechanisms of emotional reactivity that were caused by different negative events, forty-five undergraduates were selected to watch two different negative film clips, and their subjective reports were collected.

Key words: Negative events, Emotional reactivity, Subjective report, Heart Rate Variability(HRV), Gender.

摘要： 选取45名大学本科生为被试，记录被试观看内容不同的刺激材料时主观情绪体验成绩，同时采集了心率变异性（HRV）的频域指标，探讨内容不同的负性事件引发情绪反应的性别特点及外周神经机制。结果：在主观报告上，女性所诱发的负性情绪显著高于男性。社会事件的情绪材料所引发的负性情绪显著高于家庭事件的情绪材料。在生理指标上，女性在负性事件中引起的LF/HF显著高于男性。因此，负性事件后男性和女性情绪反应在主观应激强度和生理反应模式上差异显著。
