“…Previous ERP studies on the processing of gender or number agreement violations in native speakers of various languages have almost invariably shown P600 effects, at least when the violation concerned two adjacent words in the sentence (OʼRourke & Van Petten, 2011;Barber & Carreiras, 2005;Wicha, Moreno, & Kutas, 2004;Hagoort, 2003;Münte, Szentkuti, Wieringa, Matzke, & Johannes, 1997). However, the studies differ in whether they also observed an early, anterior, and often leftlateralized negativity (LAN; OʼRourke & Van Petten, 2011;Barber & Carreiras, 2005;Gunter, Friederici, & Schriefers, 2000) or not (Foucart & Frenck-Mestre, 2011;Hagoort, 2003, for the middle sentence position; Martìn-Loeches, Nigbur, Casado, Hohlfeld, & Sommer, 2006;Wicha et al, 2004). Whereas the P600 component is generally assumed to reflect strategic processes of syntactic reanalysis and repair, the LAN is probably indicative of a more automatic process of morphosyntactic reference computation (e.g., OʼRourke & Van Petten, 2011;Rossi et al, 2006;Friederici, 2002).…”
