摘要: 本研究采用事件相关电位技术(Event related potential technology, ERP)，目的是考察正性情绪对内隐多效性选择的影响及其神经机制。实验使用图片启动范式，先呈现情绪图片，然后再呈现选择刺激，被试的任务是认真看刺激并进行分类按键反应，且要求又快又准。本研究的结果发现，在P2上，对比正性情绪条件，中性条件的选择激发了更大的P2波幅；积极启动刺激比对照刺激诱发了更大的P2波幅。在N2上，中性情绪条件比正性情绪条件下的选择加工激发了更小的N2波幅；在正性情绪启动条件下，积极图片刺激比对照刺激诱发了更小的N2的波幅。在P3上，中性条件比正性情绪条件下的选择激发了更大的P3波幅；对比正性条件，中性条件下的积极图片加工得到了更大的P3波幅。这些研究结果可能表明正性情绪会影响到多效性选择的加工，二者可能有着相互交叉的加工系统，而内隐多效性一旦受到正性情绪的影响可能会表现出不稳定的特征。
Abstract: In this study, Event related potential technology (ERP) was used to investigate the effect of posi-tive emotion on implicit pleiotropic selection and its neural mechanism. The experiment uses the picture start paradigm, first presents the emotional picture, and then presents the choice stimulus. The task of the subjects is to carefully look at the stimulus and carry on the classification key response, and the requirement is fast and accurate. The results of this study showed that on P2, the selection of neutral conditions stimulated larger P2 amplitude than positive emotional conditions, and the positive start stimulation induced greater amplitude of P2 than the control stimulus. On N2, the neutral mood conditions stimulated smaller N2 amplitude than the selective processing under positive emotional conditions, and the positive picture stimulation induced smaller amplitude of N2 than the control stimulus. On P3, the neutral condition excites larger P3 amplitude than the positive emotional condition, and the positive picture processing under the neutral condition results in larger P3 wave amplitude. These findings may indicate that positive emotions may affect the processing of multiple validity choices. The two may have a cross processing system, and the implicit pleiotropic effect may show unstable characteristics once the positive emotion is affected.
