客观与主观情绪标签的差异:来自ERP的证据

Differences between Objective Affect Labeling and Subjective Affect Labeling:Evidence from EPR

采用事件相关电位技术,选择34名大学生被试,比较了客观情绪标签、主观情绪标签以及观看间的时间进程差异。结果发现:客观情绪标签下,LPP波幅在500-550ms和550-600ms两个时间窗口内均大于观看;主观情绪标签下LPP波幅与观看没有显著差异;在P3波幅上,客观情绪标签大于主观情绪标签。这提示,客观情绪标签与主观情绪标签可能在情绪评价上存在差异,进而呈现出不一样的情绪调节效果。

With the technology of ERP(event-related potential),34 college students were selected to participate in the research,which aims to distinguish the time course differences between objective affect labeling,subjective affect labeling and observing.The results show that:firstly,the LPP amplitude of objective affect labeling is larger than that of observing during the two time windows of 500-550ms and 550-600ms;secondly,there is no significant difference of LPP amplitude between the subjective affect labeling and observing;thirdly,the P3 amplitude of objective affect labeling is larger than that of subjective affect labeling.This suggests that objective affect labeling and subjective affect labeling may have differences in emotion evaluation,thus exerting different emotion regulation effects.
