The first goal of this study was to examine how individual differences in initial L2 proficiency help explain L2 grammar development in oral production during short-term immersion abroad. The second goal of the study was methodological, and evaluated challenges that can result from operationalizing learners' initial L2 proficiency as pretest…

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…

Reasserts, in response to a review of a book about language immersion programs, that the linguistic failure of immersion programs has major theoretical implications, focusing on the failure of immersion students to reach nativelike language proficiency and the failure to emphasize language accuracy.

Investigates children's changing sensitivity to processing cues for identifying agent as a function of proficiency in a second language. English speaking children in an immersion school were asked to identify the agent for a set of audiotaped sentences in English and Japanese. Found children learned word order, lexical semantics, and canonical…

Compares the lexical proficiency of 69 grade 6 immersion students with that of 22 native French-speaking peers, based on verb use and in 5 written compositions. Measures of lexical error, variety, specificity, and sophistication show clear differences between the two groups. (33 references) (Author/VWL)

Evaluates the role of age on the rate of acquiring English as a second language in an immersion setting in children with native languages typologically very different from English. Results suggest that on certain aspects of grammar, different-aged children can acquire a second language during the first three years of acquisition at similar rates…
