Sex is a psychobiological factor that is important in the process of emotion. This study determines the effect of sex on the electropsychological process of various intensities of emotional arousal.
In the Event-related Potential (ERP) session, electroencephalographic (EEG) data was recorded for 90 participants, 60% of whom were females. The participants responded to 30 universal emotional pictures, randomly chosen from the International Affective Picture System (IAPS), which were classified as invoking high, moderate, and low intensity of emotional arousal.
From the analysis of variance of two-way mixed design, the interaction between sex and emotional intensity was observed in the occipital regions (O2), indexed by the amplitude of P300 and N200 components. Males exhibited higher amplitude of P300 and N200 components (in the occipital region) as responded to high and low emotional arousal stimuli than females.
Sex is a fundamental factor that modulates psychological states in reaction to emotional stimuli.
性别是情绪过程中一个重要的心理生物学因素。本研究确定性别对不同强度情绪唤起的电心理过程的影响。
在事件相关电位（ERP）实验中，记录了90名参与者的脑电图（EEG）数据，其中60%为女性。参与者对30张从国际情感图片系统（IAPS）中随机选取的通用情感图片做出反应，这些图片被分类为引发高、中、低强度的情绪唤起。
通过双向混合设计的方差分析，在枕叶区域（O2）观察到性别与情绪强度之间的相互作用，以P300和N200成分的振幅为指标。男性在对高和低情绪唤起刺激做出反应时，枕叶区域的P300和N200成分振幅高于女性。
性别是调节对情绪刺激反应时心理状态的一个基本因素。
