This article discusses the conceptualization, measurement, and validity of a recently emerged construct in the field of second language acquisition (SLA)--implicit language aptitude (alternatively "implicit aptitude"). Implicit aptitude is a set of cognitive abilities that enable learners to make unconscious computations of the…

This book traces and summarizes the author's theoretical insights and empirical findings in the field of foreign language education. The volume explores themes such as individual differences in L1 ability and their connection to L2 aptitude and L2 achievement, L2 anxiety as an affective or cognitive variable, and the relationship between L1 and L2…

A fundamental distinction in the field of second language acquisition (SLA) is route versus rate of acquisition (or L2 development). While the former has traditionally referred to developmental sequences of learning, the latter denotes the speed with which learners progress through developmental trajectories (Muñoz, 2006). A second distinction at…

The concept of constructions has become increasingly important in theories of language acquisition and use during the last 20 years. Constructions are form-meaning pairings that are learned and stored as pieces of linguistic knowledge. Fillmore, Kay, and O'Conner (1988), and Goldberg (1995, 2006, 2019) were among the first linguists who paved the…

Deaf-sighted, deaf-blind, and hearing-sighted people have been interacting within a small community in the Bay Islands of Honduras for over a century (Ali 2023; Ali and Braithwaite 2020). In this article, we sketch the history of the community and the ways in which signers make use of their own and their interlocutor's bodies to co-construct…

Young learners' language aptitude is understudied due to a lack of tests covering this period of life. Young learners, in contrast with adults, are still acquiring their L1. Consequently, a language-dependent aptitude test should be carefully designed for it to be valid. An additional challenge is found when the young learners who are to take the…

This article revisits the role of cognitive individual differences in creating synergies between second language (L2) writing and second language acquisition research that were proposed by Kormos (2012). It takes stock of the advances in research findings, in the past decade, on the role of working memory and language learning aptitude in L2…

This paper examines evidence for relationships among individual differences (IDs) in L1 achievement, L2 aptitude, and L2 achievement. It begins by providing an overview of my academic journey from L1 educator to L2 researcher and explains the development of the Linguistic Coding Differences Hypothesis (LCDH). Next, I review Peter Skehan's…

This article is inspired by Howard Gardner's concept of linguistic intelligence and also from some authors' previous writings. All of them became the authors' reference in developing ideas on constructing a literary learning model based on linguistic intelligence. The writing of this article is not done by collecting data empirically, but by…

This article aims to discuss ten beliefs that teachers hold about second language (L2) learning and to relate these to relevant theories and approaches in the field of second language acquisition (SLA). It is especially written for L2 teachers who would like to know more about theoretical approaches that seek to explain L2 learning. Preliminary…

In this interview, JD Brown reflects on language testing/assessment. He suggests that language testing can be seen as a continuum with hard core positivist approaches at one end and post modernist interpretive perspectives at the other, and also argues that norm referencing (be it proficiency, placement, or aptitude testing) and criterion…

In the past few decades, approaches to language assessment and perspectives on learning have changed. This article highlights those developments with the greatest significance for teachers and classroom-based language assessment, including the emergence of new perspectives on the nature of language ability and learning, use of an expanded array of…

For decades educational psychologists have bemoaned the black box approach of much research on learning, that is, the focus on product rather than process, and the absence of fine-grained analysis of the learning process in the individual. One way that progress has been made on this point in the last couple of decades is through cognitive…

Investigators of first language attrition, early bilingualism and child second language learning have found common ground on a number of important points. The present review of the research will show that the study of unevenness in the early development of two languages reveals more clearly how the critical problems for future research on…

Every once in a while nature gives us insight into the human condition by providing us with a unique case whose special properties illuminate the species as a whole. Christopher is such an example. Despite disabilities which mean that everyday tasks are burdensome chores, Christopher is a linguistic wonder who can read, write, speak, understand…
