摘要：

目的：研究情绪标签的时间进程。方法：采用情绪标签的经典研究范式，结合事件相关电位技术（event-re-lated potential，ERP），让40名大学生完成情绪标签、性别标签、情绪匹配、性别匹配和观看等任务，并比较晚正成分（late positive potential，LPP）和P3波幅的差异。结果：①性别标签和观看条件LPP无显著差异；②与观看条件相比，情绪标签LPP波幅先上升后下降；③在400-450ms内情绪标签的P3波幅大于性别标签。结论：由于情绪的符号加工过程，情绪标签对情绪的调节作用可能呈现出先增强后减弱的动态过程。

Objective: To explore the time course of affect labeling. Methods: With the technology of event-related potential(ERP), forty subjects completed the tasks of affect labeling, gender labeling, affect matching, gender matching and observing. Late positive potential(LPP) and P3 component were analyzed, together with behavioral data. Results: ① There was no significant difference of LPP amplitude between gender labeling and observing; ②Compared to observing, the LPP amplitude of affect labeling increased at the beginning and decreased at the end; ③The P3 amplitude of affect labeling was larger than that of gender labeling during the time window of 400-450ms. Conclusion: The regulation effect of affect labeling may be a dynamic process which boosts then weakens emotional experience, due to the symbolic process of affect.
