Abstract It has been suggested that a high propensity for reinvestment (i.e., conscious processing of movements) can disrupt performance, but the mechanisms responsible are not well understood. The purpose of this study was to examine whether people with superior inhibition function (i.e., ability to suppress unwanted thoughts and behaviours) were better able to suppress conscious processing of their movements (i.e., reinvestment). Inhibition function was assessed using a Go/NoGo button-press task, and individual propensity for reinvestment was assessed using the Movement Specific Reinvestment Scale (MSRS) and the Decision-Specific Reinvestment Scale (DSRS). The results revealed positive associations between inhibition function and reinvestment propensity, with better inhibition function evident in people who displayed a higher propensity to reinvest (MSRS and DSRS). Hierarchical regression analyses revealed that trait anxiety moderated the relationship between inhibition and movement specific reinvestment, with higher MSRS scores associated with better inhibition function in people with low trait anxiety. This association was not significant among people with high trait anxiety. Possible explanations for these results are discussed.
