Recent research has called for the use of fine-grained measures that distinguish implicit knowledge from automatized explicit knowledge. In the current study, such measures were used to determine how the two systems interact in a naturalistic second language (L2) acquisition context. One hundred advanced L2 speakers of Japanese living in Japan…

We investigated the potential influence of implicit learning mechanisms on L2 morphosyntactic attainment by examining the relationship between age of onset (AoO), two cognitive abilities hypothesized to underlie implicit learning (phonological short-term memory and implicit statistical learning), and performance on an auditory grammaticality…

For decades educational psychologists have bemoaned the black box approach of much research on learning, that is, the focus on product rather than process, and the absence of fine-grained analysis of the learning process in the individual. One way that progress has been made on this point in the last couple of decades is through cognitive…

Few adult second language (L2) learners successfully attain high-level proficiency. Although decades of research on beginning to intermediate stages of L2 learning have identified a number of predictors of the rate of acquisition, little research has examined factors relevant to predicting very high levels of L2 proficiency. The current study,…

Investigates whether knowing more than one language enhances the learning of lexical items and syntactic constructions in other languages. Multilingual (M1) students outperformed unilinguals in both types of acquisition, suggesting that M1s' heightened metalinguistic skills, enhanced lexical knowledge, and a less conservative learning procedure…

Examines claims that unconscious second language learning under implicit and incidental conditions is insensitive to measures of individual differences in cognitive abilities, in contrast to learning under conscious rule-search and instructed conditions. Findings revealed that only in the incidental condition was the extent of learning and…
