Abstract The brain's performance monitoring system monitors ongoing actions and signals the need for cognitive control to optimize behavior under uncertainty. In the lab, performance monitoring has been studied using the flanker task, wherein a single optimal behavior exists. However, in the real world, the majority of performance monitoring occurs in contexts where there is not a single best option, and these uncertain contexts may be especially aversive for some individuals. To that end, the p...

Abstract The ability to detect and respond to errors, and to subsequently recruit cognitive control to remediate those errors, is critical to successful adaptation in a changing environment. However, there is also evidence that, for anxious individuals, this error signal is enhanced, highlighting affective and motivational influences on error monitoring. These individual differences arise as a function of both genetic influences and learning experiences. In this study, we examined punishment-bas...

Exposure to social stress is a well-established risk factor for the development and recurrence of depression. Reduced neural responsiveness to monetary reward has been associated with greater symptoms following stress exposure. It remains unclear whether reduced reward responsiveness serves as a mediator or moderator of the effects of stress on internalizing symptoms or whether similar patterns emerge with responses to social reward. We addressed this issue by measuring lifetime stress exposure ...

Abstract Individual differences in neural response to appetitive and aversive stimuli may confer vulnerability to stress-related psychopathology, including depression and anxiety. However, the specificity of this association with symptoms of depression and anxiety within the context of real-world stress is not well understood. The present study examined whether neural responses to appetitive and aversive images, measured by the late positive potential (LPP), prospectively predict symptoms of dep...

Abstract Studies suggest that individuals with alcohol use disorder (AUD) display abnormal neural error-processing, measured via the error-related negativity (ERN). The nature of the error-related abnormalities in AUD is unclear, however, as prior research has yielded discrepant findings. In addition, no study to date has attempted to characterize the dispositional nature of the ERN in AUD and directly test to what extent ERN amplitude reflects a risk factor, disease marker, and/or scar of AUD p...

Abstract Unpredictability influences emotion and attention, but its effects on goal-directed behavior are unclear. We examined whether unpredictable events interfere with performance, using event-related potentials to specify underlying attentional dynamics. The paradigm involved task-irrelevant distracters of either predictable or unpredictable content (neutral/negative) preceding targets of a stimulus discrimination task. Mean and single-trial analyses showed that unpredictable compared to pre...

Abstract Error monitoring is crucial for survival and adaptation, and can be indexed by the error-related negativity (ERN), a fronto-centrally located negative deflection in the event-related potential (ERP) waveform that differentiates erroneous from correct responses within 100 ms of a response. The ERN is seen as an early neural signal indicating the need to adjust performance and increase executive control. Previous findings indicate that punishing errors increases ERN magnitude, and that pu...
