“…English includes the focus particles only, just, even, also and too that when included in a sentence indicate that the extension of some linguistic element is to be contrasted with a set of alternatives. Some researchers have used the contrastive function of only to investigate whether non-syntactic information can guide the processing of syntactic ambiguities (Clifton, Bock, & Rado, 2000;Liversedge, Paterson, & Clayes, 2002;Ni, Crain, & Shankweiler, 1996;Paterson, Liversedge, & Underwood, 1999;Sedivy, 2002). Others have used it to investigate the acquisition and development of linguistic constraints on sentence interpretation (Crain, Ni, & Conway, 1994;Crain, Philip, Drozd, Roeper, & Matsuoka, 1992;Halbert, Crain, Shankweiler, & Woodams, 1995;Philip & Lynch, 1999).…”
