Observational study shows altered self-control in 221 participants with high impulsivity and compulsivity, suggesting performance monitoring's reduced relevance.
Key Points
Higher impulsivity and compulsivity significantly decreased self-control, leading to more failures in self-regulation and poor monitoring of errors.
Critical link observed where error-related negativity predicts better self-control only when impulsivity and compulsivity are low, highlighting their joint impact.
Electroencephalography paired with ecological momentary assessment assessed the relationship between self-control, error-related negativity, and individual traits.
Findings support the need to include impulsivity and compulsivity in cognitive models of self-control for improved understanding of behavioral outcomes.
