This study investigated the predictions of two approaches to second language acquisition. According to the usage-based approach, learner knowledge results from the strengths and weaknesses of input-driven statistical learning. According to the learner-varieties approach, pragmatic communication principles and language-internal constraints play…

Examined how acoustic variation affects second language (L2) lexical acquisition in consideration of four hypotheses: degraded input, elaborate processing, independent modulation, and robust versus strong connectivity. Beginners of L2 Spanish attempted to learn 24 Spanish words presented in 1 of 3 degrees of acoustic variation. Immediate and…
