In this study, we propose a hypothesis that domain-general auditory processing, a perceptual anchor of L1 acquisition, can serve as the foundation of successful post-pubertal L2 learning. This hypothesis was tested with 139 post-pubertal L2 immersion learners by linking individual differences in auditory discrimination across multiple acoustic…

Building up on Munro and Derwing, the current study set out to re-examine and generalize the Functional Load (FL) principle (Brown, 1988) as a tool to identify a set of relatively crucial segmental features for successful understanding in L2 communication. In Experiment 1, 40 Japanese learners of English in English-as-Foreign-Language settings…
