Intolerance of uncertainty (IU) is a transdiagnostic risk factor for internalizing disorders. Prior work has found that IU may be associated with either increased reactivity to threat or, alternatively, with decreased differential responding between threat and nonthreat/safety cues (i.e., threat generalization). For example, work by Morriss, Macdonald, & van Reekum (2016) found that higher IU was associated with increased threat generalization during acquisition (using skin conductance response ...

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 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 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...

Childhood maltreatment increases lifetime vulnerability for psychopathology. One proposed mechanism for this association is that early maltreatment increases vigilance for and attention to subtle threat cues, persisting outside of the environment in which maltreatment occurs. To test this possibility, the present study examined neural responses to ambiguous and nonambiguous threatening facial expressions in a sample of 25 adults reporting a history of low-to-moderate levels of abuse in childhood...

Abstract Background Abnormal patterns of attention to threat and reward have been proposed as potential mechanisms of dysfunction in anxiety and mood disorders. However, research on this topic has been inconsistent, perhaps because of both clinical heterogeneity in the samples assessed and measurement of attentional biases that is temporally imprecise. Methods The present study measured transdiagnostic symptoms of anxiety and depression in 205 young adults and recorded affect-modulated event-rel...
