Abstract

Highlights: The FRN component is specific to gain omission, and not necessarily by losses. We report further empirical support for the reward positivity hypothesis. Contextual valence effect is displayed across gain and loss blocks using blocked design. Abstract: Feedback processing is an important aspect of learning. In the human brain, feedback processing is often examined by measuring an event-related potential, the feedback-related negativity component. Typically, the feedback-related negativity component is investigated by directly comparing gain with loss feedback randomized across trials; however, this method does not control for confounds associated with unexpected feedback. For this study we used a blocked design gambling task to investigate the sensitivity of feedback-related negativity to positive and negative feedback separately for gains and losses. While there appeared to be no significant feedback-related negativity in the loss domain, results revealed an enlarged feedback-related negativity during the omission of gains compared to the reception of gains. These findings further support the reward positivity hypothesis which declares that the feedback-related negativity is associated with the processing of outcomes in the context of gains as opposed to losses, irrespective of unexpectedness.
