【摘要】：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。
[Abstract]:Objective: to investigate the effect of emotional titer on self-name processing by event-related potential technique.Methods: using block design, the positive and negative emotions were induced by emotional pictures. The subjects completed the passive Oddball paradigm, and responded to the small circle by keystroke, but not to the big circle and themselves, the stars, the names of strangers.The EEG differences of three kinds of names were analyzed.Results: the self-name induced by negative emotion was larger than that induced by positivity. Compared with friends and strangers, the self-name induced a larger P300 in negative emotion, but it only induced larger N2 under negative condition.Conclusion: the effect of emotional titer is affected in the middle and late period of self-processing, especially in N2 period, when negative stimulation leads to negative emotional bias, while the individual produces positive effects in order to maintain self-positive bias.The conflict of negative emotional potency.
