厌恶与恐惧情绪习得的性别差异研究:一项ERP研究

The Gender Difference Between Conditional Acquisition of Disgust and Fear:An ERPs Investigation

采用事件相关电位技术(ERPs),用条件性习得范式探讨厌恶与恐惧情绪习得的性别差异。行为结果表明,在成功习得厌恶、恐惧和中性情绪之后,男女性在唤醒度维度上,性别差异显著;脑电结果表明,在早期N1和P2成分,厌恶情绪与恐惧情绪的习得无显著性别差异;但男女不同性别在N2成分上差异显著,主要表现为女性在厌恶、恐惧、中性这三类CS的N2成分均差异显著,但男性仅厌恶与中性情绪的CS差异显著。结果表明在负性情绪的习得中,女性比男性更敏感。

In this study, we adopt classical conditioned acquisition model and used the event-related potentials （ERPs） technique to study the gender difference between conditional of disgust and conditional acquisition of fear. The behavior date suggested that all the participants were in successful emotionality conditioning and the women＇s arousal of the acquisition emotions is much larger than the men＇s. The ERPs data indicate that women show great differences in the amplitude of N2 caused separately by disgust, fear and neutral emotions; but men show significant differences between conditional disgust and neutral emotions, but no differences between fear and neutral emotions.
