选择一致性影响结果评价的ERP研究
发布时间：2019-04-08 19:50
【摘要】：本研究通过两个实验探讨了当被试主动做出与他人一致/不一致的选择行为(实验1)或看到他人做出与自己一致/不一致的选择行为(实验2)时,其选择行为的一致性是如何影响结果评价过程的。脑电数据表明在结果评价的早期阶段,无论被试是主动或被动地与他人做出相同选择,这种选择一致性都会放大输赢结果之间的差异:体现在选择一致情况下比不一致情况下诱发更大的d FRN。而在结果评价的晚期阶段,当被试先做出选择之后,看到他人做出与自己不一致的选择时(实验2),相比他人与自己选择一致时,诱发了更大的P3和LPP波幅。说明被试很可能把他人的不一致选择加工为一种冲突。因此投入了更多认知资源来加工这一结果。本研究是一个探索性的创新研究,首次从时间维度上分离了选择行为和结果反馈两个阶段,并提供了选择一致性对结果评价有影响作用的脑电证据。
[Abstract]:In this study, two experiments were conducted to explore when the subjects volunteered to make choices that were consistent / inconsistent with others (experiment 1) or when they saw others making choices that were consistent / inconsistent with themselves (experiment 2). How the consistency of choice behavior affects the outcome evaluation process. EEG data showed that at the early stages of the outcome evaluation, the subjects made the same choice, active or passive, with others. This choice consistency magnifies the difference between the results: d FRN. is induced in the case of consistency of choices than in the case of inconsistencies. In the late stage of the outcome evaluation, when the subjects first made the choice and saw that others made different choices with themselves (experiment 2), they induced larger P3 and LPP amplitudes than others did when they were in agreement with their own choices. This indicates that participants are likely to process other people's inconsistent choices as a conflict. Therefore, more cognitive resources have been invested to process this result. This study is an exploratory and innovative study, which for the first time separated the two stages of selection behavior and outcome feedback from the time dimension, and provided the EEG evidence that the consistency of choice has an effect on the evaluation of results.
