目的:分别从内隐和外显层面研究少数民族的民族自我参照效应。方法:行为实验采用R/K范式进行研究,ERP实验采用Oddball范式进行研究。结果:行为实验表明自我民族同汉族在再认率和R反应上不存在显著差异;ERP实验表明,相对于汉族和对照民族而言,自我民族在头皮中部和后中部诱发了更大的P2波幅,在全脑诱发了更小的N2波幅和更大的P3波幅,且这种效应在左脑表现更为明显。结论:当以生活在汉族地区的少数民族为被试时,民族自我参照效应只存在于内隐层面而不存在于外显层面。
Objective: To study the ethnic self-referential effect of ethnic minorities from implicit and explicit levels respectively. Methods: The behavioral experiments were conducted using the R / K paradigm. The ERP experiments were conducted using the Oddball paradigm. Results: Behavioral experiments showed that there was no significant difference in self-denominational and R-response between self-nation and Han nationality. ERP experiments showed that self-ethnic group induced greater amplitude of P2 in the middle and middle of the scalp relative to Han and control ethnic groups , Induced smaller N2 amplitude and larger P3 amplitude in the whole brain, and this effect was more pronounced in the left brain. CONCLUSION: When ethnic minorities living in the Han nationality are tested, the national self-reference effect exists only at the hidden level but not at the explicit level.
