“…By employing the event-related potential (ERP) technique, researchers put forward representative neural correlates to indicate recollection and familiarity, respectively ( Curran, 2000 , 2004 ; Küper and Zimmer, 2018 ; Horne et al, 2020 ). It has been widely accepted that the FN400 (negative ERPs peaked at 300–500 ms post-stimulus onset) old-new effect at the frontal area reflected the familiarity process, that is, the old item elicited more positive ERP component than did the new item, whereas the late positive complex (LPC; positive ERPs peaked at 500–700 ms post-stimulus onset) old-new effect at the parietal area indexed the recollection, that is, the old item elicited larger LPC than did the new item ( Curran, 2000 , 2004 ; Rugg and Curran, 2007 ; Friedman et al, 2010 ; Stróżak et al, 2016b ; Bader and Mecklinger, 2017 ; Li et al, 2017 ; Küper and Zimmer, 2018 ; Mecklinger and Bader, 2020 ). Although FN400 is considered to be similar in timing and morphology to N400, a perception/conceptual priming-related correlate ( Voss and Paller, 2009 ; Meyer et al, 2010 ; Voss et al, 2010 , 2012 ; Kutas and Federmeier, 2011 ; Dew and Cabeza, 2013 ; Hou et al, 2013 ; Pergola et al, 2014 ; Wang et al, 2015 ), most of the previous studies have shown many times that FN400 indicates the familiarity process in recognition memory ( Wang et al, 2012 ; Kamp et al, 2016 ).…”
