“…Elsewhere, it has been reported that a post-choice Centro-parietal signal with identical topography to the CPP, but traditionally labelled as the Error Positivity (Pe), also scales with choice confidence but in the opposite direction to that reported for the pre-choice CPP. The Pe is seen after erroneous choices that are explicitly reported to be incorrect (Falkenstein, 1990; Nieuwenhuis et al, 2001; Steinhauser & Yeung, 2010), and its amplitude increases the more certain participants are that they have made an error (Boldt & Yeung, 2015; Feuerriegel et al, 2022). The Pe also exhibits a build-to-threshold relationship with error signalling reports (Murphy et al, 2015), and predicts subsequent post-error slowing and post-choice information-seeking (Desender, Boldt, et al, 2019; Desender, Murphy, et al, 2019).…”
