“…Lexical competition is central to many phenomena in language including lexical access and on-line sentence comprehension (e.g., Allopenna, Magnuson, & Tanenhaus, 1998; Cutler, 1995; Levelt, Roelofs, & Meyer, 1999; McClelland & Elman, 1986; Marslen-Wilson, 1990; Norris, 1994). Lexical competition has also been proposed to play an important role in word learning in children and adults (MacWhinney, 1989; McMurray, Horst, & Samuelson, 2012; Merriman, 1999), and is a central mechanism assumed by models of cross-situational word-referent learning (Frank, Goodman, & Tenenbaum, 2009; Kachergis, Yu, & Shiffrin, 2012; Regier, 2005; Siskind, 1996; Smith, Smith, & Blythe, 2011; Yu & Ballard, 2007).…”
