“…Studies have explored self-referent processing using both functional magnetic resonance imaging (fMRI; Butterfield et al, 2023;Fossati et al, 2003;Kelley et al, 2002;Miskowiak et al, 2018;Nam et al, 2022), positron emission tomography (PET; Craik et al, 1999), and electroencephalography (EEG; Auerbach et al, 2015Auerbach et al, , 2016Dainer-Best et al, 2017;Kiang et al, 2017;Shestyuk and Deldin, 2010;Speed et al, 2016).
