【摘要】：采用事件相关电位技术和三类刺激的经典oddball范式,以内隐的方式探讨内倾特质个体的自我参照加工程度效应及其神经机制。实验发现,在P2的波幅上,在头皮前部电极、头皮前中部电极和中部电极高自我相关的刺激比其它刺激诱发了更大的P2波幅。在P2的潜伏期上,在头皮前部电极、中部电极、和中后部电极高自我相关的刺激比其它刺激诱发了更短的潜伏期。在N2的波幅上,高自我相关名字比其它刺激在左脑所诱发了更大的P2的波幅;对比内倾特质被试,中间型被试的高自我相关名字比其它刺激诱发了更大的N2的波幅。在N2的潜伏期上,高自我相关的刺激在全脑都比其它刺激诱发了更短的N2潜伏期,且中后部电极位置的潜伏期最短;两类人格被试的高自我相关名字比其它刺激诱发了更短的N2潜伏期,但中间型人格被试的潜伏期最短。在P3平均波幅上,高自我相关的刺激在全脑都比其它刺激诱发了更大的P3波幅,其中中部脑区效应最大。研究结果表明内倾特质个体的自我参照加工具有程度效应,但对比中间型个体,内倾特质个体的自我参照加工的程度效应更弱。
[Abstract]:By means of event-related potential technique and classical oddball paradigm of three stimuli, the effects of self-referential processing on introverted trait individuals and their neural mechanism were studied in an implicit way. It was found that the amplitude of P2 was higher at the anterior scalp electrode, the middle electrode and the central electrode than other stimuli. In the latency of P2, the high self-related stimuli at the anterior, middle, and posterior electrodes of the scalp were significantly shorter than those of the other stimuli. In the N 2 amplitude, the high self related names induced a larger amplitude of P2 in the left brain than other stimuli, and compared with the introverted trait subjects, the high self correlation names of the middle type subjects induced a larger amplitude of N 2 waves than the other stimuli. In the latency of N2, the stimulation of high self-correlation induced a shorter latency of N2 in the whole brain than other stimuli, and the latency of the electrode position in the middle and posterior part was the shortest. The high self correlation names of the two types of personality elicited a shorter N2 latency than other stimuli, but the intermediate personality subjects had the shortest latency. In the mean amplitude of P3, the stimulation with high self-correlation induces a larger amplitude of P3 in the whole brain than other stimuli, and the effect in the middle of the brain is the greatest. The results show that the self-referential processing of introverted trait individuals has a degree effect, but the degree effect of introverted trait individuals' self-referential processing is weaker than that of intermediate individuals.
