How the Brain Processes Feedback: An EEG Perspective

Abstrakt:

Feedback is a fundamental mechanism underlying processes such as learning and adaptive decision-making. Many theoretical frameworks, including reinforcement learning models and performance monitoring accounts, propose that the brain evaluates outcomes either in terms of their valence or by comparing expected and actual results. These processes can be studied using electroencephalography (EEG), which provides temporally precise markers of feedback processing, such as the Feedback-Related Negativity (FRN/RewP) and later components associated with attention and evaluation. 

This talk provides an overview of the role of feedback in cognition from an EEG perspective, focusing on how neural responses to outcomes are shaped by experimental context. Empirical findings highlight that feedback processing varies across different task contexts, including tasks that differ in their cognitive demands. Neural responses are also modulated by how feedback is represented, with differences observed across various formats (e.g., colors, symbols, text). Together, these findings indicate that both task context and feedback representation systematically influence neural responses.
