“…On a different front, a tradition of experimental psycholinguistic research has investigated how bilinguals of different proficiency levels in the two languages access or retrieve lexical items, or process sentences on-line, and how the two linguistic systems prime or inhibit each other (Grosjean and Soares, 1986;Grosjean, 1994;de Groot, 1995;de Groot and Kroll, 1997;Nicol, 2001, Dussias, 2003among others). With the exception of work by Seliger (1991;, Sharwood Smith and van Buren (1991), Platzack (1996), Polinsky (1997), Sorace (2000a), Toribio (2001), Gürel (2002) and Montrul (2002), much remains to be done to understand the formal and linguistic nature of the attrition process in a bilingual context and how it affects the human language faculty. One major reason why this area of research has remained relatively underexplored until now is perhaps the lack of theoretical and methodological tools to investigate the phenomenon (for discussion, see Sharwood Smith and van Buren, 1991).…”
