Increasing evidence supports the presence of an anhedonic endophenotype in major depressive disorder (MDD), characterized by impairments in various components of reward processing, particularly incentive motivation, effort‐based decision making, and reward learning. In addition to its prominent role in MDD, reward processing dysregulation has been proposed as a transdiagnostic risk and/or maintenance factor for a range of other forms of psychopathology. Individuals with social anxiety disorder (SAD)—a condition that frequently co‐occurs with MDD—demonstrate low trait positive affectivity and altered processing of rewards and positively valenced information. However, no studies to date have directly tested reward learning—the ability to modulate behavior in response to rewards—in this population.

社交焦虑症和重性抑郁症中隐性奖励学习的诊断和维度评估。

越来越多的证据支持在重度抑郁症（MDD）中存在无性行为型内表型，其特征是奖励处理的各个组成部分都存在障碍，特别是激励动机，基于努力的决策和奖励学习。除了其在MDD中的突出作用外，还提出了奖惩处理失调作为多种其他形式的精神病理学的转诊风险和/或维持因素。患有社交焦虑症（SAD）的人（一种经常与MDD并发的疾病）表现出低特质的积极情感以及改变了对奖励和正价信息的处理。但是，到目前为止，还没有研究直接测试过这种人群中的奖励学习（即调节行为以响应奖励的能力）。
