Electrophysiological indices of response inhibition in a Go/NoGo task predict self-control in a social context

Abstract

Recent research demonstrates that response inhibition - a core executive function - may subserve self-regulation and selfcontrol. However, it is unclear whether response inhibition also predicts self-control in the multifaceted, high-level phenomena of social decision-making. Here we examined whether electrophysiological indices of response inhibition would predict self-control in a social context. Electroencephalography was recorded as participants completed a widely used Go/NoGo task (the cued Continuous Performance Test). Participants then interacted with a partner in an economic exchange game that requires self-control. Results demonstrated that greater NoGo-Anteriorization and larger NoGo-P300 peak amplitudes - two established electrophysiological indices of response inhibition - both predicted more self-control in this social game. These findings support continued integration of executive function and self-regulation and help extend prior research into social decision-making processes. © 2013 Nash et al.
