“…To this aim, we devised a factorial design where we could thoroughly explore the interplay of relevance with uncertainty during reward anticipation at the SPN level, and we eventually assessed whether these two variables showed mainly independent effects, or rather a synergistic one during this process (see Figure 1 A). To achieve this, we extracted and analyzed the SPN component from an existing ERP study by Walentowska et al (2016), in which a speeded Go/NoGo task was used (previously validated extensively across different ERP studies, Pourtois, 2010, 2012;Godefroid et al, 2016;Koban et al, 2012;Paul et al, 2017;Pourtois, 2011;Severo et al, 2017;Vocat et al, 2008). In this previous study, both the response-locked (CRN), and stimulus/feedback-locked (FRN and P3) components were carefully analyzed and reported, but not the SPN.…”
