“…The RewP peaks approximately 250–350 ms after feedback onset over frontocentral sites as an enhanced positivity to reward or positive feedback compared to neutral or negative feedback (Figure 3). The RewP is thought to reflect reinforcement learning processes and is sensitive to manipulations that influence the value of rewards, including delay (Cherniawsky & Holroyd, 2013), certainty (Muir et al., 2021), and perceived control (Harmon‐Jones et al., 2020; Mühlberger et al., 2017). Studies leveraging both EEG and neuroimaging methods indicate correlations between the RewP and activation of reward‐related brain regions, including the ventral striatum and medial prefrontal cortex (Becker et al., 2014; Carlson et al., 2011; Foti et al., 2014).…”

Depression is a prevalent, heterogeneous, and debilitating disorder that often emerges in adolescence, and there is a need to better understand vulnerability processes to inform more targeted intervention efforts. Psychophysiological methods, like event‐related potentials (ERPs), can offer unique insights into the cognitive and emotional processes underlying depression vulnerability. I review my and others' research examining ERP measures of reward responsiveness in youth depression and present a conceptual model of the development of low reward responsiveness, its role in depression vulnerability, and potential windows for targeted intervention. There is evidence that a blunted reward positivity (RewP) is observable in children at risk for depression, appears to be shaped in part by early social experiences, and predicts later depressive symptoms in combination with other risk factors like stress exposure. Further, a component consistent with RewP is reliably elicited in response to social acceptance feedback in computerized peer interaction tasks and demonstrates unique associations with social contextual factors and depressive symptoms, supporting the utility of developing psychophysiological tasks that may better capture youths' real‐world experiences and social risk processes. In addition, I address the translational implications of clinical psychophysiological research and describe a series of studies showing that a reduced RewP predicts greater reductions in depressive symptoms with treatment but is not modifiable by current treatments like cognitive behavioral therapy. Finally, I describe our preliminary efforts to develop a positive emotion‐focused intervention for the offspring of depressed mothers, informed by the RewP literature, and describe future directions for translating psychophysiological research to intervention and prevention.

The influence of effort expenditure on the subjective value in feedback involving material reward has been the focus of previous research. However, little is known about the impact of effort expenditure on subjective value evaluations when feedback involves reward that is produced in the context of social interaction (e.g. self–other agreement). Moreover, how effort expenditure influences confidence (second-order subjective value) in feedback evaluations remains unclear. Using electroencephalography, this study aimed to address these questions. Event-related potentials showed that, after exerting high effort, participants exhibited increased reward positivity difference in response to self–other (dis)agreement feedback. After exerting low effort, participants reported high confidence, and the self–other disagreement feedback evoked a larger P3a. Time–frequency analysis showed that the high-effort task evoked increased frontal midline theta power. In the low (vs. high)-effort task, the frontal midline delta power for self–other disagreement feedback was enhanced. These findings suggest that, at the early feedback evaluation stage, after exerting high effort, individuals exhibit an increased sensitivity of subjective value evaluation in response to self–other agreement feedback. At the later feedback evaluation stage, after completing the low-effort task, the self–other disagreement feedback violates the individuals’high confidence and leads to a metacognitive mismatch.
