Grammatical complexity has been established as a key indicator of language and writing development (Ortega 2003; Bulté and Housen, 2014; Crossley and McNamara 2014). The present study uses the Register-Functional approach to complexity (Biber et al. 2022) to compare the development of L1 English and L2 English writers across year of study and…

Conversely to plenty of studies describing how L1 transfer affects L2 systems, where the two grammars, L1/L2, often only come to interact later in life, less is known of dominant language transfer in heritage language grammars. Unlike in L2 speakers, the dominant language of the heritage speaker potentially affects its weaker language already from…

This article concerns the use of a matched-guise task in a language documentation project, showing how such a perceptual tool can be used to highlight ongoing language change and attitudes towards an endangered language. Baba Malay, an endangered creole spoken by the Peranakans, has two forms of words encoding coarseness or refinedness. Words…

Most of the world's population has knowledge of at least two languages. Many of these bilinguals are also exposed to and identify with at least two cultures. Because language knowledge enables participation in cultural practices and expression of cultural beliefs, bilingual experience and cultural identity are interconnected. However, the specific…

This study reports a meta-analysis that synthesizes the empirical research on the role of language aptitude in second language grammar acquisition. A total of 33 study reports were identified including 17 predictive studies that investigated the correlations between aptitude and ultimate L2 attainment and 16 interactional studies that examined the…

The present article examines the relationship between age and dominance in bilingual populations. Age in bilingualism is understood as the point in development at which second language (L2) acquisition begins and as the chronological age of users of two languages. Age of acquisition (AoA) is a factor in determining which of a bilingual's two…

The present study focuses on the influence of starting age and input on foreign language learning. In relation to starting age, the study investigates whether early starters in instructional settings achieve the same kind of long-term advantage as learners in naturalistic settings and it complements previous research by using data from oral…

Many age-related second language (L2) studies have confirmed that young children have a better chance to become nativelike in L2 acquisition than adults. The current study investigated whether age effects exist in the L2 acquisition of Japanese and whether nativelike proficiency is guaranteed for early child L2 starters after constant target…

This article provides a selective overview of recent event-related brain potential (ERP) studies in L2 morpho-syntax, demonstrating that the ERP evidence supporting the critical period hypothesis (CPH) may be less compelling than previously thought. The article starts with a general introduction to ERP methodology and language-related ERP profiles…

In the present study, we surveyed the English language-learning motivations of 518 secondary school students, university students, and young adult learners in the capital of Chile, Santiago. We applied multi-group structural-equation modeling to analyze how language-learning goals, attitudes, self-related beliefs, and parental encouragement…

This paper investigates whether any difference exists in the degree of second language attrition between two siblings in terms of grammatical complexity, grammatical accuracy, lexical complexity, and lexical productivity based on their storytelling data collected over the period of 31 months. The subjects' L1 and L2 are Japanese and English,…

The effects of age on second language acquisition constitute one of the most frequently researched and debated topics in the field of Second Language Acquisition. Two different orientations may be distinguished in age-related research: one which aims to elucidate the existence and characteristics of maturational constraints on the human capacity…

In the emerging tradition of language socialization research, this study examines the changing bilingual self-perceptions of three children, identical twin girls and their older brother, from early adolescence through early adulthood. The children were reared in a predominantly French-speaking home in south Louisiana by French/English bilingual…

Research on social markedness and second language pronunciation is reviewed, and some general conclusions are drawn. A number of issues arising from this research are identified and inherent difficulties in forming hypotheses, performing analyses, and interpreting data are discussed. (30 references) (Author/MSE)

Arguments raised against the Critical Period Hypothesis of second language learning are refuted. It is suggested both that sufficient research evidence exists to support the hypothesis and that the hypothesis was not represented accurately or contradicted convincingly in the criticisms. (Author/MSE)
