Motivation is a key topic that comprises considerable theoretical and practical implications, and its study is gaining increasing traction in recent years. Employing both behavioral and neural techniques, previous studies examined the extent to which intrinsic and extrinsic motivations collectively shape individual decision making. Investigations found that both processes play indispensable and interactive roles in choice behavior. However, despite its importance, little is known respecting the role of extrinsic social factors in contributing to individual variations in intrinsic motivation. Toward elucidating the role of extrinsic social factors in motivated decision making, the current study implements the stop watch task, combined with hyper-recording electrophysiological measurements. With the electrophysiological toolkit, our goal is to bring to light how extrinsic social signals impact intrinsic motivation and shape the reward processing over success and failure at the succeeding stage. Empirically, we show that, following social outcome presentation, there is an increased divergent feedback-related negativity (FRN), which reflects the failure/success discrepancy at the outcome stage of choice behavior. In summary, this study demonstrates the saliency of social information in intrinsic motivational processes that underpin success-failure outcomes.
动机是一个关键主题，具有相当多的理论和实践意义，近年来对其研究越来越受到关注。以往的研究运用行为和神经技术，考察了内在动机和外在动机共同塑造个体决策的程度。研究发现，这两个过程在选择行为中都发挥着不可或缺的交互作用。然而，尽管其很重要，但关于外在社会因素在个体内在动机差异形成中的作用却知之甚少。为了阐明外在社会因素在动机性决策中的作用，本研究采用了秒表任务，并结合超记录电生理测量。借助电生理工具，我们的目标是揭示外在社会信号如何影响内在动机，并在后续阶段塑造对成功和失败的奖励处理。从经验上看，我们表明，在呈现社会结果后，与反馈相关的负波（FRN）差异增加，这反映了选择行为结果阶段的失败/成功差异。总之，本研究证明了社会信息在支撑成败结果的内在动机过程中的显著性。
