The role of motivation in action inhibition: an ERP study

Abstract

Event Abstract Back to Event The role of motivation in action inhibition: an ERP study Hanne Schevernels1*, Ruth M. Krebs1, Klaas Bombeke1 and C N. Boehler1 1 Ghent University, department of Experimental Psychology, Belgium Reward is usually thought to be inherently coupled to action execution rather than inhibition (Guitart-Masip et al., 2011, 2012). Recently however, studies of Boehler et al. (2012, 2014) have shown that motivation can also improve inhibition of an already initiated motor action by modulating event-related reward associations in a Stop-signal task, with fMRI data suggesting that this effect relies on enhanced activity within key areas of what is often considered the response-inhibition network. In the current study a similar paradigm was used in an EEG setting to gain further insights into the temporal dynamics of the interaction of motivation and response inhibition. Moreover, we included a block in which no reward could be won to be able to explore global reward effects. Our results suggest that motivation globally boosts attention, thereby improving response inhibition in all stop trials. Moreover selective event-related reward can also influence brain processes related to motor inhibition at a relatively early stage (starting at 200 ms after Stop-signal presentation), suggesting enhanced reactive control. These findings provide knowledge about neural mechanisms underlying reward processing and response inhibition. This is of particular interest not only to gain insights into healthy brain functioning, but also to neurological disorders showing motivational deficits and/or difficulties inhibiting actions, like Parkinson’s disease and impulse control disorders.
