    Abstract

    In the cognitive psychology literature, auditory processing has been extensively researched and suggested as a foundation of first language acquisition in childhood. This study tests an emerging theoretical view that the same faculty underpins post-pubertal L2 pronunciation learning. A total of 100 late English-Polish bilinguals in the UK with diverse age and experience backgrounds were assessed for their ability to represent various characteristics of sounds via behavioural and neurophysiological measures. Subsequently, the participants’ biographical backgrounds and auditory processing profiles were compared to various dimensions of their L2 pronunciation proficiency. According to the results of mixed-effects modeling analyses, individual differences in participants’ L2 pronunciation proficiency were equally accounted for by age (age of arrival), experience (length of residence), and auditory processing (encoding, reproduction). Within the current dataset, the degree of auditory precision was negatively associated with participants’ chronological age (19-45 years). The findings suggest that earlier age of onset may allow them to take advantage of more precise auditory processing, which in turn helps them to make the most of every input opportunity throughout extensive immersion experience, leading to more advanced L2 phonological skills in the long run.
