“…Lexical accent learning in beginning learners of L2 Japanese may be partially constrained by phonological short-term memory (PSTM) capacity and auditory processing ability, as learners lack substantial experience with the acoustic cues to lexical accent and possess a small lexical store (Martin & Ellis, 2012;Sunderman & Kroll, 2009). Exploring these capacities is vital because they may account for some of the previously observed variation in L2 accent acquisition (e.g., Nishinuma, Arai, & Ayusawa, 1996;Taylor, 2011). Although the involvement of domain-general capacities in L2 suprasegmental acquisition has been examined before (e.g., Bowles et al, 2016;Goss & Tamaoka, 2019;Shport, 2015;Wong & Perrachione, 2007), this relationship needs further exploration in beginning learners of a pitch-accent language, as these capacities may play a greater role in early-stage L2 learning (Hummel, 2009).…”
