摘　　要：目的:探讨金钱激励延迟(monetary incentive delay,MID)和情感激励延迟(affective incentive delay,AID)任务潜在神经加工过程的异同。方法:对29名健康大学生分别进行MID和AID的ERP检测。期待阶段以cue-P3和CNV波幅为指标,目标反应阶段以target-P3波幅为指标;结果反馈阶段以FRN与feedback-P3成分的峰峰波幅为指标,分别比较在两种任务的三个加工阶段上述脑电成分之间的差异。结果:①在期待和目标反应阶段,MID诱发出了比AID更大的cue-P3成分(P<0.001)。②在结果反馈阶段,无论正、负反馈,AID诱发出了比MID更大的FRN-P3峰峰波幅(P<0.05)。结论:MID和AID任务的不同加工阶段分别涉及不同的潜在神经机制,这对后续采用合适的研究范式来开展针对性的应用研究具有重要意义。Objective： The aim of the present study was to explore the differences of the event-related potentials be- tween monetary incentive delay（MID） task and affective incentive delay（AID） task. Methods： 29 healthy undergraduates were administered to perform the MID and AID task, during which their brain EEG responses were recorded by neuroscan. We separately compared the cue-P3 and CNV amplitudes in the anticipation processing phase, target-P3 amplitude in the target-response processing phase, and the difference in the amplitudes between FRN and feedback-P3 in the feedback pro- cessing phase of the two tasks. Results： During incentive anticipation, cue-P3 amplitude was significantly larger for MID than AID. In the feedback phase, no matter positive or negative feedback, the differences in amplitudes between FRN and feedback-P3 was larger for AID than MID. Conclusion： The results suggest that neural processing of anticipation and con- sumption is specific to incentive type, which may have implications for future studies to adopt suitable paradigm to carry out applied research.
