Dissociable effects of reward and expectancy during evaluative feedback processing revealed by topographic ERP mapping analysis
Evaluative feedback provided during performance monitoring (PM) elicits either a positive or
negative deflection~ 250–300 ms after its onset in the event-related potential (ERP)
depending on whether the outcome is reward-related or not, as well as expected or not.
However, it remains currently unclear whether these two deflections reflect a unitary
process, or rather dissociable effects arising from non-overlapping brain networks. To
address this question, we recorded 64-channel EEG in healthy adult participants performing …
