An increasing number of adults learn more than one foreign language simultaneously. While the cognitive benefits of using multiple languages from birth have been studied extensively, little is known about possible cognitive benefits of learning multiple languages simultaneously in adulthood. Among the cognitive abilities which play a role in…

After discussing key issues in the aptitude literature and presenting an updated, multicomponential model of cognitive language aptitude, we consider two analyses from a longitudinal investigation using aptitude to predict success in language learning. Aptitude is conceptualized as a special talent for learning languages and a ceiling on success.…

Skill acquisition theorists conceptualize second language (L2) learning as the acquisition of a set of perceptual, cognitive, and motor skills. The dominant view in skill acquisition theory is to regard L2 skill acquisition as a three-stage process "from initial representation of knowledge through initial changes in behavior to eventual…

This paper focuses on the importance of multilingual literacy in the 21st century and, specifically, how adult learners across the globe can develop multilingual literacy skills necessary for successful communication and global citizenship. The paper includes a theoretical (research background, definitions, critical framework) and a practical…

We investigated age-related decline in adult learning of Dutch as an additional language (Ln) in speaking, writing, listening, and reading proficiency test scores for 56,024 adult immigrants with 50 L1s who came to the Netherlands for study or work. Performance for all four language skills turned out to decline monotonically after an age of…

Calls to diversify second language acquisition (SLA) (e.g., Ortega, 2013) have led to increased interest in multilingualism and inclusion of groups less represented in samples of university students, such as individuals at older ages. Nevertheless, we still have more questions than we do answers. This article outlines a research agenda targeting…

This study draws on conceptual and methodological insights afforded within a dynamic systems perspective to explore shifting interrelationships between cognitive capacity and motivational resources in instructed adult second language (L2) learners of Spanish at increasing proficiency. Relationships that emerged showed both stability and…

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,…

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…

This paper investigates the influence childhood bilingualism has on adult foreign language learning ability. Early research exploring the influence of bilingualism on general intelligence is mentioned as well as recent studies that present more favorable results. It is hypothesized that childhood bilingualism will have a positive effect on adult…

Six of 11 papers presented at a symposium on language aptitude testing are included in this document. "Cognitive Abilities in Foreign Language Aptitude: Then and Now" (John B. Carroll) reconsiders language aptitude testing 30 years after publication of the Modern Language Aptitude Test (MLAT). "Preliminary Investigation of the…
