“…This study does not include the collection of new corpora of monolingual data in English and French; for reference to monolingual development we refer to previously published evidence in the literature (see Prévost, 2009, for a thorough overview). The acquisition of articles in young English- and French-speaking children has been studied both naturalistically (e.g., Bassano, 1998; Bloom, 1970; Brown, 1973; Kupisch, 2003; Müller, 1994; Pine & Lieven, 1997) and experimentally (e.g., Garton, 1983; Karmiloff-Smith, 1979; Maratsos, 1974; Stevenson & Sims, 1993; Warden, 1976).…”
