In this study, neural representation of adult second language (L2) speakers' implicit grammatical knowledge was investigated. Advanced L2 speakers of Japanese living in Japan, as well as L1 Japanese speakers, performed a word-monitoring task (proposed as an implicit knowledge test) in the MRI scanner. Behavioral measures were obtained from…

This study examined how discriminability and prototypicality of nonnative phones modulate the amplitude of the Mismatch Negativity (MMN) event-related brain potential. We hypothesized that if a frequently occurring (standard) stimulus is not prototypical to a listener, a weaker predictive memory trace will be formed and a smaller MMN will be…

The high-variability training paradigm (multiple words, phonetic contexts, and talkers) has been successful for perceptual learning of tone contrasts. Here, it is extended to training native English listeners on Tokyo Japanese pitch-accent contrasts. Participants had no previous experience with lexically contrastive pitch patterns. They learned to…

This study investigated the effects of word frequency, collocational frequency, L1 congruency, and L2 proficiency, on L2 collocational processing. Two groups of L1 Japanese speakers of English (intermediate and advanced) and one group of English native speakers (NSs) performed an online acceptability judgment task on four types of adjective-noun…

Although expanding spacing is often regarded as the most effective practice schedule, studies comparing equal and expanding spacing have yielded mixed results. The present study set out to examine whether the amount of spacing and the retention interval may influence the effects of expanding and equal spacing on second language (L2) vocabulary…

This study investigates subject pronominal expression in second language Chinese and compares learner usage with patterns found in their first language. The results show that (a) overt pronouns are used more for singular, +animate subjects than plural, -animate ones; (b) switch in subject surface form favors overt pronouns; (c) English and Russian…

Most studies that have investigated the effects of instruction on the SLA of specific grammatical features have focused on intentional learning. This study investigated incidental acquisition by comparing the relative effects of two types of instruction--comprehension-based instruction (CBI) and production-based instruction (PBI)--on young…

This article reports on a crosslinguistic comparative study of the processing of Japanese relative clauses (RCs) by Chinese-, Sinhalese-, Vietnamese-, Thai-, and Indonesian-speaking second language (L2) learners. A robust finding in studies on the acquisition of RCs in L2 English and other European languages is that subject-gap RCs are easier than…

This comparative analysis of teacher-student interaction in two different instructional settings at the elementary-school level (18.3 hr in French immersion and 14.8 hr Japanese immersion) investigates the immediate effects of explicit correction, recasts, and prompts on learner uptake and repair. The results clearly show a predominant provision…

This study extends previous research on the relationships among intelligibility, perceived comprehensibility, and accentedness. The researchers obtained accent and comprehensibility ratings and transcriptions of accented speech of Cantonese, Japanese, Polish, and Spanish intermediate English-as-a-Second-Language students from native English…
