“…Studies (Alexopoulos et al, 2012; Boksem & de Cremer, 2010; Fabre et al, 2015; Hewig et al, 2011; Hu et al, 2014; Osinsky et al, 2013; Polezzi et al, 2008; Qu et al, 2013; Riepl et al, 2016; Wang et al, 2017) analyzing ERPs during the UG have reported mainly two components: the Medial Frontal Negativity (MFN) and a parietal positivity that authors refer to as P3, P300, or Late Positive Potential (LPP) (here, we will use the term P3/LPP). (Note that other components, in particular the P2 (Weiß et al, 2019; Weiß, Mussel, & Hewig, 2020; Weiß, Rodrigues, et al, 2020) and the N2 (Weiß et al, 2019; Weiß, Mussel, & Hewig, 2020) have also been reported in some studies using a modified version of the UG). The MFN typically presents a frontocentral distribution and latency of 200–350 ms after stimuli onset and shows greater negativity for negative than for positive events (Glazer et al, 2018).…”
