- •
Information about the outcomes is conveyed trial-by-trial by two evoked EEG waves.
- •
FRN and F-P300 are contingent with feedback presentation and sensitive to outcome valence.
- •
F-P300 is sensitive to outcome magnitude only in conjunction with task difficulty.
- •
Task difficulty has opposite effects on these components.
- •
FRN and F-P300 reflect different cognitive processes which depend on the behavioral context.
