“…In ERP research, three components that represent a signature of interference are typically discussed: the N2, the N450, and the sustained potential (SP). The N2 component represents a negative fronto-central deflection that emerges between 250 and 350 ms after stimulus onset (Clayson & Larson, 2011;Gehring, Gratton, Coles, & Donchin, 1992;Kopp, Rist, & Mattler, 1996;Spapé, Band, & Hommel, 2011). The N450 is also a frontocentral negative-going deflection that peaks approximately 450 ms after stimulus onset (Larson, Kaufman, & Perlstein, 2009;Liotti, Woldroff, Perez, & Mayberg, 2000;Markela-Lerenc et al, 2004;West, 2003;West, Bowry, & McConville, 2004;West, Jakubek, Wymbs, Perry, & Moore, 2005).…”
