The reinforcement sensitivity theory (RST) relates individual differences in reward sensitivity to the activation of the behavioral
approach system (BAS). Dopamine-related brain structures have been repeatedly associated with reward processing, but also
with cognitive processes such as task switching. In the present study, we examined the association between reward sensitivity
and the event-related fMRI BOLD response with set switching in 31 males. As expected, the right inferior frontal cortex (rIFG) and
the striatum (i.e. the left putamen) were involved in set-switching activity for the overall sample. Interindividual differences in
Gray’s reward sensitivity were related to stronger activity in the rIFG and the ventral striatum. Thus, trait reward sensitivity
contributed to the modulation of brain responsiveness in set-switching tasks. Having considered previous research, we propose
that higher BAS activity is associated with a stronger reward to process a better implementation of goal-directed tasks and the
diminished processing of secondary cues. [-]
