“…Lexical and semantic/conceptual manipulations such as semantic fit between a word and its preceding context (Kutas & Hillyard, 1980), lexical status (Bentin, 1987), semantic priming (Bentin, McCarthy, & Wood, 1985), word frequency (Barber, Vergara, & Carreiras, 2004), and probability of occurrence within a given word string (Kutas & Hillyard, 1984) elicit a negative deflection peaking around 400 ms after the presentation of a stimulus (the N400 effect). In contrast, a large positive deflection with an onset at about 500 ms and a duration of several hundred milliseconds (the P600 effect) is elicited by a disparate set of syntactic anomalies, including violations of phrase structure (Hagoort, Brown, & Groothusen, 1993; Neville, Nicol, Barss, Forster, & Garrett, 1991; Osterhout & Holcomb, 1992), subcategorization (Ainsworth‐Darnell, Shulman, & Boland, 1998; Osterhout & Holcomb, 1992; Osterhout, Holcomb, & Swinney, 1994) and violations in agreement of number, gender, and case (Frenck‐Mestre, Foucart, Carrasco, & Herschensohn, 2009; Frenck‐Mestre, Osterhout, J. McLaughlin, & Foucart, 2008; Hagoort et al, 1993; Osterhout & Mobley, 1995). Although some studies have reported an anterior negativity within a window ranging from 150 to 500 ms to some syntactic anomalies (the Left Anterior Negativity, or LAN: Friederici, 1995; Hahne & Friederici, 1999; Neville et al, 1991; Osterhout & Holcomb, 1992; Osterhout & Mobley, 1995), the P600 effect is more reliably correlated with syntactic manipulations.…”
