Reward prediction error signals associated with a modified time estimation task

Psychophysiology. 2007 Nov;44(6):913-7. doi: 10.1111/j.1469-8986.2007.00561.x. Epub 2007 Jul 19.


The feedback error-related negativity (fERN) is a component of the human event-related brain potential (ERP) elicited by feedback stimuli. A recent theory holds that the fERN indexes a reward prediction error signal associated with the adaptive modification of behavior. Here we present behavioral and ERP data recorded from participants engaged in a modified time estimation task. As predicted by the theory, our results indicate that fERN amplitude reflects a reward prediction error signal and that the size of this error signal is correlated across participants with changes in task performance.
