不通过5种感觉通道情感交流的事件相关电位研究

Event-related potential study on emotional communication not through five conventional senses

摘要:

目的：在两个成人情侣（发送者和接收者）间，寻找5种感觉通道之外进行情感交流的脑电活动证据。方法：采用高密度事件相关电位（event-related potential，ERP）技术，以不同的情绪视觉刺激材料：中国情绪图片（chinese affective picture system，CAPS），中国情绪面孔图片（chinese affective face picture system，CAFPS）诱发发送者的事件相关电位差异表现的同时，观察接收者（接受的是无差异的视觉刺激）的ERP表现。结果：在CAPS试验中：对于发送者，负性情绪图片与较中性情绪图片诱发的ERP成分存在显著差异（370～430 ms：F=5.478；500～550 ms：F=13.852，P<0.05），与此同时，接受者的ERP在各种刺激条件下的差别：负性情绪图片与较中性情绪图片诱发了更正的晚成分（370～430、500～550、600～800 ms：F=3.880、4.776、7.441，P<0.05）。在CAFPS试验中：在发送者辨别不同情绪的ERP存在显著差别的前提下，3种情绪条件下接受者的ERP在各时间段差别无统计学差异。结论：5种感觉通道之外，成人情侣间进行情感交流有脑电活动的证据，可能在同时发生，也可能存在延迟效应。交流的内容更趋向于有自我体验的情感内容。

Abstract:

Objective：To seek for the evidences of electrical activity of emotional communication in the brain of couples（named as sender and receiver） excluding five conventional senses（look，listen，touch，smell，taste）. Methods：We induced performances of event-related potential（ERP） of senders by applying ERP technique and using Chinese affective picture system（CAPS） and Chinese affective face picture system（CAFPS） as stimuli. Simultaneously，we observed the ERP performances of receivers who received the same visual stimulation as senders. Results：During CAPS test，there were significant differences in ERP performances of senders in－duced by neutral pictures and negative pictures（370-430 ms：F=5.478；500～550 ms：F=13.852，P<0.05）. Simultaneously，under differ－ent stimuli of sender，ERP performances of receivers showed significant differences in late potentials（370-430，500-550，600-800 ms：F=3.880，4.776，7.441，P<0.05）. In CAPFS test，there was no statistical difference in ERP performances of receivers stimulated by pic－tures of happy face，sad face and angry face while ERP performances of sender showed significant differences. Conclusions：Evidences of electrical activity of emotional communication in the brain of couples are existed excluding five conventional senses，which may oc－cur at the same time or occur in delay and its content is about self-experiences.
