本研究以22名男生和21名女生为被试，考察了情绪反应的性别差异。受试者观看一组60张情绪标准化幻灯片，分为愉快、中性和不愉快，同时记录惊吓反射、诱发电位、心率、面部肌电图和皮肤电导。惊吓反射幅度，一个由杏仁核和眶额皮质调节的指数，对厌恶的情绪刺激敏感，女性总体上更大。此外，惊吓情绪调制是更大的女性与男性。慢诱发电位（400-800毫秒），一种代表情绪反应认知成分的测量方法，揭示了左前额叶部位的性别差异，女性对不愉快的幻灯片比愉快的幻灯片表现出更大的积极性，而男性对愉快的幻灯片比中性幻灯片表现出更大的积极性。与男性相比，女性认为所有幻灯片不那么令人愉快，并报告了更大的唤醒不愉快的条件。结果是符合已知的功能性大脑差异，在水平的边缘系统和脑边缘系统的结构，男性和女性之间，并指出生物接地更大的敏感性和脆弱性的妇女不利/压力事件。(C)2011 Elsevier Inc.

Gender differences in emotional responses have been investigated in two groups of students, 22 males and 21 females. Participants watched a set of sixty emotional standardized slides divided into pleasant, neutral and unpleasant, while Startle reflex, Evoked Potentials, Heart Rate, facial EMG and Skin Conductance were recorded. Startle reflex amplitude, an index modulated by amygdala and orbitofrontal cortex and sensitive to aversive emotional stimuli, was overall larger in women. In addition, startle emotion modulation was greater in women with respect to men. Slow Evoked Potentials (400-800 ms), a measure representing the cognitive component of the emotional response, revealed gender differences in the left prefrontal site, with women showing greater positivity to unpleasant compared with pleasant slides while men had greater positivity to pleasant vs. neutral slides. Women, compared with men, perceived all slides as less pleasant and reported greater arousal to unpleasant condition. Results are in line with known functional brain differences, at level of limbic and paralimbic structures, between men and women, and point to biologically grounded greater sensitivity and vulnerability of women to adverse/stressful events.
