This research examines the effect of response (in)consistency on the first mover's anticipation and evaluation of the performance feedback in gambles. In a two-player gambling task, the participant played as the first mover while the confederate served as the second mover, who made their gambles in sequence. A more pronounced feedback-related negativity (FRN) was observed when the first mover noticed that the second mover chose a different option from him/her. An enlarged stimulus-preceding negativity (SPN) was observed when the first mover was anticipating the final feedback in this condition. Interestingly, consistent responses gave rise to a more pronounced FRN difference wave (d-FRN) during the feedback stage. Taken together, these results suggest that response discrepancy would modulate the first mover's anticipation and evaluation of the final feedback in gambles.
本研究考察了反应（不）一致性对先行者在赌博中对绩效反馈的预期和评价的影响。在一个两人赌博任务中，参与者作为先行者，而同盟者作为后行者，两人依次进行赌博。当先行者注意到后行者选择了与自己不同的选项时，观察到更明显的反馈相关负波（FRN）。当先行者在这种情况下预期最终反馈时，观察到刺激前负波（SPN）增大。有趣的是，在反馈阶段，一致的反应会产生更明显的FRN差异波（d-FRN）。综上所述，这些结果表明反应差异会调节先行者在赌博中对最终反馈的预期和评价。
