“…One idea, supported by a growing body of research, is that successful second-language acquisition is related to musical ability. This follows from broader links between musical and linguistic processing in the native language (for reviews, see e.g., Patel, 2008;Slevc, 2012), including evidence that individual differences in grammatical ability and speech processing are related to musical ability (e.g., Gordon et al, 2015;Jansen et al, 2023;Lee et al, 2020;Nayak et al, 2022). For example, musical ability predicts the distinctiveness of neural responses to closely related speech sounds (Parbery-Clark et al, 2012), speech discrimination performance (Swaminathan & Schellenberg, 2020), and sensitivity to prosody (Jansen et al, 2023;Morrill et al, 2015).…”
