Widespread use of the Modern Language Aptitude Test (MLAT) in L2 studies of individual differences implicitly assumes that L2 aptitude is a distinct cognitive facet. There is considerable evidence for prediction from L1 abilities to L2 learning. In this longitudinal study, L1-MLAT-L2 relations were examined in 307 US secondary students based on…

This study presents a reanalysis of existing data to investigate whether a relationship between perception and production abilities regarding a challenging second-language (L2) phonological contrast is observable (a) when both modalities must rely on accessing stored lexical representations and (b) when there is an asymmetry in task focus between…

This longitudinal study explored the roles of item- and learner-related variables in L2 learners' development of productive collocation knowledge (L1 = Dutch; L2 = German; NLearners= 50). Learners' form recall knowledge of 35 target collocations was measured three times over a 3-year period. The item-related variables investigated were L1-L2…

Research suggests new foreign language (FL) words are learned more easily if their phonology follows the phonotactic rules of the native language. Very little is known, however, about the impact of orthography on FL learning. This study investigated the cognitive mechanisms supporting the learning of words with familiar and unfamiliar…

This longitudinal study with time-serial data examines for the first time whether different types of intraindividual variation in second language (L2) performance and cognitive functioning are related, and how and when they influence L2 development longitudinally in older adulthood. We analyzed the L2 development of 26 German-speaking adults aged…

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…

Whereas many scholars have emphasized the relative importance of "comprehensibility" as an ecologically valid goal for L2 speech training, testing, and development, eliciting listeners' judgments is time-consuming. Following calls for research on more efficient L2 speech rating methods in applied linguistics, and growing attention toward…

The article reports on the findings of a study investigating the relationship between first language (L1) and second language (L2) fluency behavior. Drawing on data collected from Turkish learners of English, the study also addresses the question of whether proficiency level mediates the relationship, if any. The data were coded for a range of…

Using advanced quantitative methods, this article demonstrates that cumulative exposure to the school language is the best language experience predictor of proficiency in that language (as indexed by sentence repetition, lexical semantic, and discourse semantic tasks) in a highly diverse group of 5- to 7-year-old bilingual children in monolingual…

The current study examined the extent to which cognitive fluency (CF) contributes to utterance fluency (UF) at the level of constructs. A total of 128 Japanese-speaking learners of English completed four speaking tasks--argumentative task, picture narrative task, reading-to-speaking task, and reading-while-listening-to-speaking task--and a battery…

Sleep plays a role in the consolidation of various aspects of language learning. In this study, we investigated the extent to which sleep-dependent memory consolidation contributes to second language (L2) rule generalization and enhancement of L2 explicit knowledge. One hundred native English speakers were engaged in a meaning-focused training of…

This study examined the linguistic dimensions of comprehensibility and perceived fluency in the context of L2 argumentative speech elicited from 40 Japanese-speaking learners of English. Their speaking performance was judged by 10 inexperienced native speakers of English for comprehensibility and perceived fluency, and was also objectively…

Language-analytic ability, or the ability to treat language as an object of analysis and arrive at linguistic generalizations, is at the core of the constructs of language learning aptitude and metalinguistic awareness, which are implicated in our ability to learn explicitly. In the context of child second language (L2) learning, it has been…

This study examined the role of visual cues (facial expressions and hand gestures) in second language (L2) speech assessment. University students (N = 60) at English-medium universities assessed 2-minute video clips of 20 L2 English speakers (10 Chinese and 10 Spanish speakers) narrating a personal story. They rated the speakers'…

This study systematically examines the moderating effects of task type and L2 proficiency on the relationship between L1 and L2 simultaneously across reading and writing tasks with different levels of cognitive complexity. Main and moderating effects were evaluated through structural equation modeling analyses. First, both L1 skills and L2…
