Adversity and error-monitoring: Effects of emotional context

Area of Science:

• Neuroscience
• Psychology
• Cognitive Science

Background:

• Childhood adversity is linked to long-term psychological and cognitive effects.
• Error processing is crucial for adaptive behavior and learning.
• Emotional stimuli can modulate cognitive processes, including error monitoring.

Purpose of the Study:

• To investigate the relationship between self-reported childhood adversity and neural markers of error processing.
• To examine whether emotional context influences this relationship.
• To explore the impact of adversity on executive functioning and emotion regulation.

Main Methods:

• 99 undergraduates completed selective attention tasks (Stroop) with emotional and non-emotional words.
• Electroencephalography (EEG) recorded neural activity, focusing on error-related potentials (ERN, Pe) and alpha oscillations.
• Participants completed self-report measures for childhood experiences, executive functioning, depression, stress, and emotion regulation.

Main Results:

• Childhood adversity correlated with self-reported executive functioning difficulties, independent of depression and stress.
• Adversity predicted an enhanced error-related negativity (ERN) and blunted error-positivity (Pe) during emotional tasks.
• Adversity was associated with altered error-related alpha oscillations, suggesting reduced responsiveness in emotional contexts.

Conclusions:

• Childhood adversity alters neural mechanisms of error processing, particularly in emotional contexts.
• Adversity may lead to heightened initial error detection but impaired sustained error processing during emotional challenges.
• These neural alterations occur without significant changes in overt task performance, highlighting subtle cognitive impacts of adversity.
