“…RewP amplitude is more positive for gain trials as opposed to loss trials (in the case of the FRN, more negative for loss trials; Lohse et al, 2020;Miltner et al, 1997;Proudfit, 2015), and is greater for rewards that are larger in magnitude (Meadows et al, 2016). Uncertain outcomes also elicit greater RewP amplitude compared to certain outcomes (Hajcak et al, 2007;Pfabigan et al, 2011;Walentowska et al, 2019), but RewP amplitude may be equally effected whether the outcome is better than expected or worse than expected (Ferdinand et al, 2012;however, see Mulligan & Hajcak, 2018). Notably, higher RewP amplitude during feedback processing is associated with behavioral adjustments on subsequent trials following erroneous responses (Cohen & Ranganath, 2007;Lohse et al, 2020;Schultz, 2016), suggesting that the RewP indexes the signal between neural networks that adjusts future behavior.…”
