情绪性注意瞬脱的认知机制:来自行为与ERP的证据
发布时间：2018-07-17 17:11
【摘要】：从过度投入理论与激活反弹理论对瓶颈理论的质疑出发,采用ERP技术检验了情绪性注意瞬脱的加工过程及其神经机制。行为结果显示,以恐惧面孔为T1,中性场景图片为T2,则恐惧面孔T1相对中性面孔T1显著降低了中性T2的识别正确率,进而诱发了情绪性注意瞬脱。ERP结果进一步显示,相较于中性面孔T1,恐惧面孔T1诱发的情绪加工影响了代表中枢加工资源的两阶段P3波幅,使得其始终高于代表标准注意瞬脱的中性面孔T1条件和代表非注意瞬脱的单任务基线条件。以上结果证明,情绪性注意瞬脱形成自情绪性T1加工所诱发的中枢资源过度投入,而非源自中枢资源瓶颈。
[Abstract]:Based on the theory of excessive input and the theory of activation rebound, the processing process and neural mechanism of emotional attention transients are tested by ERP technology. The behavioral results showed that when the fear face was T 1 and the neutral scene image was T 2, the recognition accuracy of the fear face T 1 was significantly lower than that of the neutral face T 1, which induced emotional attention transient. ERP results further showed that the fear face T 1 was significantly lower than that of the neutral face T 1. Compared with the neutral face T1, the emotional processing induced by fear face T1 affected the amplitude of P3, which represented the central processing resource. It is always higher than the neutral face T 1 condition representing standard attention transient and the single task baseline condition representing non attention transient. These results suggest that emotional attention transients were induced by emotional T1 processing, but not from central resource bottlenecks.
