This study examines the storage versus composition of Spanish inflected verbal forms in first language (L1) and second language (L2) speakers of Spanish. L2 participants were selected to have mid-to-advanced proficiency, high classroom experience, and low immersion experience, typical of medium-to-advanced foreign language learners. Participants…

Recent currents in language learning research highlight the social and emergent aspects of second language (L2) development and recognize that learners need opportunities for interaction in meaningful contexts supported by explicit attention to language itself. These perspectives suggest new ways of conceptualizing the challenges faced by children…

This article reports the results of an experiment designed to investigate the effectiveness of pinyin (a phonic transcription system) in learning vocabulary of Chinese as a second language from the perspective of cognitive load theory. In the reported experiment, the learning effects of the vertical and horizontal layouts of characters, pinyin,…

This study investigates the production of the English interdental fricative [theta] by Chinese learners of English, using a variationist framework. Twenty-seven Chinese participants were asked to evaluate the acceptability of four possible substitutes for the variable (th) and to perform four oral production tasks. The results indicated that…

Given that this special issue is devoted to the acquisition and processing of inflectional morphology by second language (L2) learners, the question in the title may appear redundant. However, recent research on first language (L1) and L2 morphological processing has challenged basic assumptions about the status of inflectional morphology in…

Despite considerable research interest, data-driven learning (DDL) has not become part of mainstream teaching practice. It may be that technical aspects are too daunting for teachers and students, but there seems to be no reason why DDL in its early stages should not eliminate the computer from the equation by using prepared materials on…

In this article, I describe studies conducted over 25 years with secondary and post-secondary L2 learners in the United States. The evidence from these studies shows that there are important connections between students' early L1 skills and their L2 aptitude and L2 proficiency and that individual differences in students' L1 skills in elementary…

We report a classroom experiment directed at increasing lexical fluency in writing. Participants were 107 Dutch students in bilingual (EFL) education (Grades 10 and 11). According to current theories of writing such fluency allows writers to devote more attention to higher order aspects of text production, such as idea generation, selection and…

The aim of the article is to examine how first language attrition research on maturational constraints interprets and links its findings to current views on maturation in the field of second language acquisition. It is argued that attrition research exhibits certain inconsistencies in the interpretation of the structural characteristics of the…

Studies about bilingualism and second language acquisition (SLA) have a long tradition within linguistic and psycholinguistic research. The contributions from psycholinguistic research are crucial to the improvement of neurolinguistic models. This importance stems from the fact that psycholinguistic research is posing more specific questions than…

Practice is not meant to be understood as the opposite of theory, DeKeyser wrote; instead, practice involves specific activities in an L2 that learners engage in, deliberately, with the goal of developing knowledge of and skills in the L2. In the book "Discursive Practice in Language Learning and Teaching," by "practice" the author means something…

Language is a complex adaptive system: Speakers are agents who interact with each other, and their past and current interactions feed into speakers' future behavior in complex ways. In this article, we describe the social cognitive linguistic basis for this analysis of language and a mathematical model developed in collaboration between…

This article presents a selective overview of studies that have investigated how advanced adult second language (L2) learners process morphologically complex words. The studies reported here have used different kinds of experimental tasks (including speeded grammaticality judgments, lexical decision, and priming) to examine three domains of…

This article argues that a native-speaker baseline is a neglected dimension of studies into second language (L2) performance. If we investigate how learners perform language tasks, we should distinguish what performance features are due to their processing an L2 and which are due to their performing a particular task. Having defined what we mean…

Language is a product of both biological and cultural evolution. Clues to the origins of key structural properties of language can be found in the process of cultural transmission between learners. Recent experiments have shown that iterated learning by human participants in the laboratory transforms an initially unstructured artificial language…
