内、外部情绪标注对情绪作用的ERPs研究
Can Subjective Affect Labeling Dampen the Emotions?-ERPs study

以往情绪标注的研究发现描述情绪面孔的情绪（外部情绪标注）可以降低被试的情绪。但是描述自己的情绪（内部情绪标注）结果如何尚存争议。研究采用了ERPs技术，以愉快和悲伤情绪面孔为实验材料，选择18名大学本科生为被试，比较了内部情绪标注、外部情绪标注及性别标注之间的差异。结果发现：外部情绪标注和性别标注相比，其LPP波幅均小于性别标注下LPP波幅，并且这种差异在Pz、CPz、Cz、FCz、Fz五个电极点均类似；而内部情绪标注和性别标注相比，其LPP波幅均小于性别标注下LPP波幅，但仅表现在Pz、CPz、Cz三个点上。这说明：无论内部情绪标注还是外部情绪标注，在命名后均能抑制情绪。研究结果支持阻断理论。
Multiple studies suggest objective affect labeling can dampen affect-related responses, for example, the affect-related responses of participants were lower during labeling the emotional faces compared to control condition. However, there have dissimilar opinions about the effect of subjective affect labeling(i.e., labeling ones own emotion) on affect-related respondes. The present study used positive and negative emotional faces as experimental materials, with happy emotional face images as positive stimuli and sad emotional face images as negative stimuli. Half of these faces were male, and half were female. The research used a 3 (labeling types)×2 (emotion types) experimental design, in which there were three levels of labeling types:subjective affect labeling, objective affect labeling and gender labeling. And emotion types had two levels:sad and happiness. In the Experiment, the objective affect labeling condition referred to observing the facial emotion expressed in the description given below the face, and then selecting the appropriate word (angry or happy). Subjective affect labeling refers to observing the face pictures, and then selecting the appropriate word (angry or happy) accoding to the feeling of the paticipant. Gender labeling refers to observing the face pictures, and then choosing the right words for the face's gender (Li Na or Zhang Tao). If the subject believed the face images are men, they should choose the marked word "Zhang Tao", or "Li Na" if they believe the images are women. The results show that:the amplitudes of objective affect labeling in the LPP were lower, compared with gender labeling, regardless of positive emotion or negative emotion.
