Event-Related Potential Components Associated with Reward Processing Across Three Stages: Cue Evaluation, Reward Anticipation, and Feedback Receipt

	Cue Evaluation	Feedback Anticipation	Feedback Receipt
	cP300	SPN	fRewP	fP300
Certain vs Uncertain	-	Uncertain > Certain	Uncertain > Certain	Uncertain > Certain
Valence Effect	Reward and Loss > Neutral	Reward and Loss > Neutral	Reward > Neutral > Loss	Reward and Loss > Neutral

Note: Certain > uncertain indicates that ERPs are larger for certain events than for uncertain events. The impact of certainty on cP300 has not been studied independently of valence effects. The valence effect describes the pattern of findings for reward, loss, and neutral outcomes. For a recent review, see Glazer et al. (2018). cP300 = cue P300; SPN = stimulus-preceding negativity; fRewP = feedback reward positivity; fP300 = feedback P300
