Monitoring the consequences of our behaviour and processing the feedback from our environment are both important for learning. Since motivation is known to influence a variety of cognitive processes, the current study aims to identify which particular aspects of feedback processing can be influenced by monetary incentives. To this end, participants (target N=48) will perform a time estimation task while their electroencephalogram is recorded. To differentiate between expectedness and valence, participants will receive adaptive performance feedback, resulting in infrequent positive and infrequent negative (20%, respectively) as well as frequent neutral feedback (60%). One group will be incentivised for obtaining positive feedback, while the other group will be incentivised for avoiding negative feedback. We will use event-related potentials (FRN, P300) to investigate whether early and late feedback processing is influenced by expectancy, valence, and motivation, respectively. We expect to replicate the finding that the FRN differentiates between expected and unexpected feedback. The FRN might additionally be influenced by motivation as reflected in larger FRNs in the respective incentive condition. We expect the P300 to be sensitive to feedback relevance and, thus, to be influenced by the motivational incentive. Accordingly, we expect to see larger P300 amplitudes for positive feedback in the group instructed to obtain positive feedback, whereas the group instructed to avoid negative feedback is predicted to elicit larger P300 amplitudes following negative feedback. Investigating the relationship between motivation and feedback processing will allow for a better understanding of feedback-based learning and associated dopaminergic functioning.
