【摘要】：采用事件相关电位考察正性情绪对自我参照加工程度效应的影响。实验采用图片启动范式,先呈现情绪图片,然后再呈现自我参照刺激。实验发现,在P2上,中性情绪条件比正性情绪条件激发了更大的波幅,高自我相关的刺激比其它刺激诱发了更短的P2潜伏期;在N2上,高自我相关名字比中等自我相关名字和非自我相关名字诱发了更小的N2的波幅和更长潜伏期;在P3上,高自我相关名字比中等自我相关名字和非自我相关名字诱发了更大的P3波幅,中等自我相关名字比非自我相关名字诱发了更大的P3波幅。实验结果表明,人类大脑对正性情绪刺激的加工可能是不敏感的。无论在正性情绪启动还是中性启动的影响下,自我参照加工都能展现出稳定的特征,而且高自我相关的刺激会得到更为深入和精细的加工,表现出自我参照加工的程度效应。
[Abstract]:The effect of positive emotion on self-reference processing was investigated by event-related potential. The experiment used the image priming paradigm, first presented the emotional picture, then presented self-reference stimulation. It was found that in P2, neutral emotional conditions stimulated a larger amplitude than positive emotional conditions, and high self-related stimuli induced shorter P2 latencies than other stimuli; in N2, Higher self-related names induce a smaller amplitude and longer latency of N2 than moderate and non-self-related names; on P3, Higher self-related names and non-self-related names induced larger P3 amplitudes than middle self-related names and non-self-related names, and middle self-related names induced larger P3 amplitudes than non-self-related names. The results suggest that the human brain may be insensitive to the processing of positive emotional stimuli. Under the influence of positive emotion priming and neutral priming, self-referential processing can show stable characteristics, and the high-self-related stimuli can be processed more deeply and finely, showing the degree effect of self-referential processing.
