Adversity and error‐monitoring: Effects of emotional context

Abstract This study tested whether self‐reports of childhood adversity would predict altered error processing under emotional versus non‐emotional task conditions. N = 99 undergraduates completed two selective attention tasks, a traditional color‐word Stroop task and a modified task using emotional words, while EEG was recorded. Participants also completed self‐report measures of adverse and positive childhood experiences, executive functioning, depression, current stress, and emotion regulation. Reports of adversity were robustly correlated with self‐reported challenges in executive functioning, even when controlling for self‐reported depression and stress, but adversity was not correlated with task performance. With regard to neural markers of error processing, adversity predicted an enhanced error‐related negativity and blunted error‐positivity, but only during the emotion‐word blocks of the task. Moreover, error‐related changes in alpha oscillations were predicted by adversity, in a pattern that suggested less error responsiveness in alpha patterns during the emotion block, compared to the color block, among participants with higher adversity. Overall, results indicate alterations in error monitoring associated with adversity, such that in an emotional context, initial error detection is enhanced and sustained error processing is blunted, even in the absence of overt performance changes.
