In this article, I argue that first language (L1), second language (L2) and third language (L3) acquisition are fundamentally the same process, based on learning by parsing. Both child and adult learners are sensitive to fine linguistic distinctions, and language development takes place in small steps. While the bulk of the article focuses on…

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…

Languages spoken in larger populations are relatively simple. A possible explanation for this is that languages with a greater number of speakers tend to also be those with higher proportions of non-native speakers, who may simplify language during learning. We assess this explanation for the negative correlation between population size 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,…

A study is reported investigating whether reported sequence of acquisition of grammatical morphemes for second language learners would be found to exist in tasks other than that requiring speech production. (Author/RM)

In earlier work we have shown that adults, young children, and infants are capable of computing transitional probabilities among adjacent syllables in rapidly presented streams of speech, and of using these statistics to group adjacent syllables into word-like units. In the present experiments we ask whether adult learners are also capable of such…

The intermediate competence of adult second language learners is qualitatively different from native speaker competence. Learning strategies are constants in the diachronic modifications of learner competence. A study of the acquisition of interrogatives in French reveals limited strategies and the heterogeneity of linguistic models needed to…

A review of research on the development of linguistic competence in second language learners looks at the role played by input to children in their development of linguistic competence, the nature of children's metalinguistic development, and the same processes in the naturalistic second language learning of adults, and then examines the role of a…

Reports a study of the learning strategies and processes of four adult learners of Chinese, using data collected over a two-year period. Students showed a number of different approaches to learning, not all of which could be classified "good language learner" strategies. Findings suggest areas for exploration in immersion education, especially…

A study investigated late emergence, in learners of English as a Second Language, of the ability to interpret object gaps in purpose clauses (PCs). Subjects were 34 adult native speakers of French. Results indicate difficulty interpreting only PCs with prepositional object gaps, supporting the hypothesis that syntactically marked construction may…

The fact that some people learn a second language more easily than others has prompted numerous studies designed to link one factor or another with successful language learning. This work examines a large number of these studies to assess the importance of various factors involved in language learning. The influencing factors suggested are grouped…

The report details results of a research project to monitor and map the literacy development of three learners of English as a Second Language (ESL) studying in an Australian English program for adult migrants. The objective was to gain a longitudinal picture of their reading and writing development over a period of nine months. Five additional…

Current research on adult second language learning suggests that study is necessary to separate interference variables from intralinguistic variables and to determine the relative difficulty of structures in each group. This research on the acquisition of the English relative clause was specifically designed to test the transfer hypothesis…

This article discusses second language vocabulary learning strategies and includes an analysis and classification of possible strategies and the report of a study conducted among second language learners in Japan. Research on vocabulary learning strategies is synthesized into two lists of strategies: 14 methods for initial learning of a new word's…

The language learner is activated by exposure to primary linguistic data in the target language, categorizes that data and deduces from it a system of rules or hypotheses. When the language acquisition process is successful, as is virtually always the case in first language acquisition, the learner's rule system corresponds to that of the speech…
