奖励敏感性是理解抑郁本质的核心维度。心理生理学对这一结构的研究主要集中在奖励积极性，一个事件相关电位（ERP），指标完善的奖励敏感性。本研究扩展了以往的研究，集中在ERP的指数奖励的动机组成部分。一个新的努力奖励任务被用来引发动机和完善的ERP。由34名抑郁症参与者和32名无抑郁症参与者组成的小组在一系列奖励相关的ERP中进行了比较。患有抑郁症的参与者在高努力支出后表现出对努力完成线索的反应性降低，在低努力支出后对奖励的预期降低（即，消极性之前的刺激），以及高努力支出之后的奖励积极性降低。在获得奖励之前发生的ERP解释了抑郁状态的独特差异，并在抑郁个体的亚组之间进行了区分。研究结果支持利用多个ERPs的索引单独的奖励处理缺陷，以更好地表征抑郁症和抑郁亚型的效用。
Reward sensitivity is a dimensional construct central to understanding the nature of depression. Psychophysiological research on this construct has primarily focused on the reward positivity, an event-related potential (ERP) that indexes consummatory reward sensitivity. This study extended prior research by focusing on ERPs that index the motivational component of reward. A novel effort-for-reward task was used to elicit motivational and consummatory ERPs. Groups consisting of 34 participants with depression and 32 participants without depression were compared across a range of reward-related ERPs. Participants with depression exhibited reduced responsivity to effort completion cues following high effort expenditure, reduced anticipation of rewards after low effort expenditure (i.e., the stimulus preceding negativity), and reduced reward positivity following high effort expenditure. ERPs occurring prior to reward receipt accounted for unique variance in depression status and differentiated between subgroups of depressed individuals. Findings support the utility of leveraging multiple ERPs that index separate reward processing deficits to better characterize depression and depressive subtypes.
