Abstract:

Feedback plays a crucial role in real life. Learning from the informative feedback, human being could master general skills and knowledge for adapting to the environment. As an important factor of feedback processing, feedback interval means the duration between initiation of behavior and the appearance of feedback stimulus. However, the prior research about how the feedback interval modulated feedback processing did not reach consistent viewpoint. Introduced both the behavioral and ERP studies about how feedback interval affects feedback processing, and analyzed the reasons for the results discrepancies among these studies. Finally, we propose the necessity to standardize the definition of feedback interval and the combination of the behavioral and electrophysiological methods in further research.

Key words: feedback interval, feedback processing, feedback-related negativity, delayed feedback, immediate feedback
