学习通常需要对一个人行为的后果进行反馈，这可能会促使学习者改变他们的行为。动机可能决定一个人对这种反馈的敏感度，特别是在一些学生比其他学生更看重学业成绩的教育背景下。因此，一项任务的动机可能会影响对绩效反馈的重视，以及它在改善学习方面的有效性。为了研究内在动机和反馈处理之间的相互作用，我们在基于动机访谈的新操作之前和之后使用了基于反馈的学习的功能磁共振成像(FMRI)，这是一种在心理健康环境中增强治疗动机的技术。由于纹状体在强化学习系统中的作用，纹状体在基于动机的学习调节中发挥着重要作用。与这一想法一致的是，任务期间的动机水平与纹状体对积极反馈与消极反馈的敏感性有关。此外，在简短的激励性访谈后，动机的增强与左侧内侧颞叶反馈敏感度的增加有关。我们的结果表明，动机调节了神经对与表现相关的反馈的反应，而且动机的变化促进了支持学习和记忆的区域的处理。
Learning commonly requires feedback about the consequences of one’s actions, which can drive learners to modify their behavior. Motivation may determine how sensitive an individual might be to such feedback, particularly in educational contexts where some students value academic achievement more than others. Thus, motivation for a task might influence the value placed on performance feedback and how effectively it is used to improve learning. To investigate the interplay between intrinsic motivation and feedback processing, we used functional magnetic resonance imaging (fMRI) during feedback-based learning before and after a novel manipulation based on motivational interviewing, a technique for enhancing treatment motivation in mental health settings. Because of its role in the reinforcement learning system, the striatum is situated to play a significant role in the modulation of learning based on motivation. Consistent with this idea, motivation levels during the task were associated with sensitivity to positive versus negative feedback in the striatum. Additionally, heightened motivation following a brief motivational interview was associated with increases in feedback sensitivity in the left medial temporal lobe. Our results suggest that motivation modulates neural responses to performance-related feedback, and furthermore that changes in motivation facilitates processing in areas that support learning and memory.
