Successful execution of goal-directed actions entails continuous monitoring of ongoing actions and evaluation of their outcomes and contexts. The evaluative component of performance monitoring (PM) has been extensively documented in the electrophysiological domain through two event-related potential (ERP) markers: the Feedback-Related Negativity (FRN) and P3 components. Our recent work revealed that motivational demands can influence and shape the course of PM at the level of these ERP components. More specifically, we demonstrated that the feedback’s relevance or importance to one’s goal (referred to as goal impact) modulated the FRN (& P3) component in a general way. In that, regardless of its valence, the feedback of higher goal impact showed an overall less negative FRN than that of lower goal impact, suggesting a general decrease in monitoring for the former relative to the latter. As a follow up, we ran a between-subjects design experiment in which 40 participants completed a speeded Go/No Go Task while 64-channel electroencephalography was recorded concurrently. Critically, participants were randomly assigned to two goal impact conditions (high vs. low), manipulated through instructions on the supposed diagnosticity of the task, while maintaining the reward probabilities constant (i.e., deviant positive vs. frequent negative feedback). The current ERP results replicated our initial findings. Furthermore, we noted significant differences in the internal monitoring (at the response-locked level) between the two experimental groups, akin to the pattern at the feedback-locked level. This replication of previous findings stamps the idea that PM brain processes are context dependent and influenced by motivational effects.
