Sad mood, emotion regulation, and response inhibition

ABSTRACT

Affect-as-information models, resource allocation models, and arousal biased competition theory predict different effects of mood on cognition. To test these theories, this study examines the effect of sad mood on response inhibition (RI) and whether emotion dysregulation impacts this potential relationship. Participants were 273 undergraduates who wrote about either a typical day or a sad event from their life. They self-reported mood and emotion regulation difficulties, and RI was a composite score of Colour-Word Stroop, Stop-Signal, and go/no-go computerised tasks. The intensity of self-reported sad mood did not affect RI as predicted, but those who wrote about sad events had worse RI. Worse emotion regulation also predicted worse RI. Cognitive loads, rumination, and mind-wandering are discussed as possible mechanisms. Findings are extended from well-established areas such as working memory to the less-established area of RI.
