内隐自我正面偏见效应的ERP研究
An ERP Study on Implicit Self-positivity Bias Effect
摘要
Abstract
Objective: To investigate the complex relationship between self-reference and emotional valence at implicit level and to find the evidence of implicit self-positivity bias. Methods: Event-related brain potentials were recorded when participants performed emotional judgment tasks (positive/negative) in self or non-self primed conditions, using emotional Chinese words under Supraliminal Attitude-Prime Paradigm. Tlie ERPs were compared among self-positive, self-negative, non-self positive and non-self negative information. Results: ERP waveforms showed an interaction between self-reference and emotional valence in the time range of the N400 component. Larger N400 amplitudes occurred after self-positive and non-self negative words as compared with self-negative and non-self positive words. In a word, the results showed larger ERP negative amplitudes in the words within self-positivity bias. Conclusion: The processing of self-reference and emotional valence are closely associated at implicit level and confirmed the existence of implicit self-positivity bias.关键词
