“…The P3 is a centro‐parietal positivity that appears after the FRN when elicited by outcome feedback (Polezzi, Sartori, Rumiati, Vidotto, & Daum, 2010; Wu & Zhou, 2009; Zhang et al., 2013). When investigating feedback processing, the P3 is often associated with the emotional significance of outcome feedback (Gu et al., 2011; Luo et al., 2014; Wu & Zhou, 2009). Both the FRN and the P3 have been reported to be sensitive to the degree of information uncertainty, but it is unclear whether they reflect different aspects of ambiguous feedback processing (Ernst & Steinhauser, 2015; Gibbons, Schnuerch, & Stahl, 2016; Hirsh & Inzlicht, 2008; Polezzi et al., 2008; Polich, 1990).…”
