目的:通过事件相关电位技术考察情绪效价对自我姓名加工的影响。方法:采用block设计,使用情绪图片分别诱发正、负性情绪,被试完成被动Oddball范式,对小圆进行按键反应,而对大圆及自我、明星、陌生人姓名不反应,分析三类姓名的脑电差异。结果:负性情绪下的自我姓名比正性诱发了更大的N2,相比于朋友与陌生人,自我姓名在正、负性情绪下诱发了更大的P300,但仅在负性条件下诱发了更大N2。结论:情绪效价作用在自我姓名加工的中晚期时间段内产生影响,特别是在N2时间段内,负性刺激引起情绪负性偏向,而个体同时为了维护自我正面偏见,产生了正、负性情绪效价的冲突。
Objective: To investigate the influence of emotion potency on the process of self-name by using event-related potential technique. Methods: Using block design, emotion images were used to induce positive and negative emotions respectively. The subjects completed the passive Oddball paradigm, performed the key reaction to the small circle, but did not respond to the names of the big circle, self, star and stranger. EEG differences. Results: Self-name under negative emotion induced more N2 than positive, self-name induced greater P300 in positive and negative emotions than friends and strangers, but only under negative conditions Induced greater N2. CONCLUSIONS: Emotional potency has an impact on the middle and late time periods of self-name processing. Especially during the N2 time period, negative stimuli cause emotional negative bias. Individuals also have positive and negative positive self-confidence in order to maintain self-positive biases Conflict of sexual emotions.
