“…In the language domain, as infants grow older, they become more sensitive to native contrasts, but less sensitive to non-native contrasts (e.g. Harrison, 2000;Kuhl, Williams, Lacerda, Stevens, & Lindblom, 1992;Mattock & Burnham, 2006;Mattock, Molnar, Polka, & Burnham, 2008;Werker & Tees, 1984;Yeung, Chen, & Werker, 2013; but see also Liu & Kager, 2014). Similarly, in the music domain, infants become more capable of discriminating melodies that conform to the structure in the ambient input (Lynch & Eilers, 1992;Trainor & Trehub, 1992;Trehub, Schellenberg, & Kamenetsky, 1999).…”
