基于性别差异的情绪词汇诱发电位认知功能研究

A Study on the Cognitive Function of Potential Evoked by Emotional Vocabulary Based on Gender Differences

摘要: 目的：应用多通道ERPs分析技术，探讨情绪词汇加工脑神经认知方面的性别差异性ERPs神经机制。方法：应用不同情绪效价的情绪刺激图片对60位健康志愿者进行情绪效价五个水平情绪情绪脑电诱发电位的测试判别。观察不同性别对五个情绪效价水平情绪词汇的情绪反应的差异。结果：对情绪词汇的反应时间差异，男性较女性反应时间明显缩短，两性对极负性和正性情绪词汇反应时间较快，对中性词汇和偏负性情感词汇反应时间延迟。情绪词汇加工ERPs的性别的统计学差异早期分布于双侧眶额顶皮层，中晚期则分布于双侧眶额顶广泛记忆注意整合网络。结论：情绪词汇的认知加工调节存在明显的性别差异。推测与文化教育、社会环境、家庭背景、激素水平等因素相关。

Abstract: Objective: To investigate the gender differences on emotional vocabulary cognitive processing function of cranial nerve electrical activity mechanism with multi-channel ERPs. Methods: Emotion stimulus pictures of different emotional valence were applied on 60 healthy volunteers to test the five-level emotional valences of emotional evoked potential. The gender differences on emotional vocabulary cognitive processing function and emotional reactions on five emotional valence levels of emotional vocabulary were observed. Results: Male volunteers’ response time on the emotional vocabulary was much shorter than the females. Comparatively speaking, both of them were faster on the most negative and positive emotional vocabulary, and a longer reaction time on the neutral words and partial negative emotional vocabulary was needed. The gender statistical differences on the ERPs of emotional vocabulary processing were early distributed in bilateral orbital frontal parietal cortex, and were distributed later in bilateral orbitofrontal top wide memory and attention integration network. Conclusions: There are obvious gender differences on the cognitive processing of emotional vocabulary, which is hypothesized to be related to cultural background, social environment, family background, hormone level and other factors.
