This study examined the simultaneous effects of L2 individual difference (ID) variables (aptitude, motivation, strategy use, language processing experience, and gender) on English as a foreign language (EFL) breadth and depth of L2 vocabulary knowledge of 492 Korean university-level learners. Independent variable measures included the: (1) Korean…

This study compares the performance of native speakers and adult second language (L2) learners on tasks tapping proficiency in grammar, vocabulary, and collocations. In addition, data were collected on several predictors of individual differences in linguistic attainment, including some related to language experience (print exposure, education,…

While a substantial body of empirical evidence has been accrued about the role of individual differences in second language acquisition, relatively little is still known about how factors of this kind can mediate the effects of instructional practices as well as how empirically-derived insights can inform foreign language pedagogy, both with…

Studies with U.S. secondary second language (L2) learners have revealed individual differences (IDs) in first language (L1) skills and L2 aptitude and shown that these IDs are related to L2 achievement and proficiency. In this study, U.S. students were administered measures of L1 achievement, L1 cognitive processing, and L2 aptitude; followed…

Most second language researchers agree that there is a role for corrective feedback in second language writing classes. However, many unanswered questions remain concerning the linguistic features to target and the type and amount of feedback to offer. This study examined essays by 151 learners of English as a second language (ESL), in order to…

This state-of-the art paper focuses on the poorly explored issue of foreign language aptitude, attempting to present the latest developments in this field and reconceptualizations of the construct from the perspective of neuroscience. In accordance with this goal, it first discusses general directions in neurolinguistic research on foreign…

Second language (L2) educators have proposed a unique anxiety for general L2 learning and an anxiety specific to L2 reading. Since the early 1990s, the L2 anxiety concept has been challenged on theoretical and empirical grounds. In this investigation, U.S. high school L2 learners were administered the Foreign Language Reading Anxiety Scale (FLRAS)…

Background: Nonverbal communication deficits are characteristic of autism spectrum disorder (ASD) and have been reported in some later-born siblings of children with ASD (heightened-risk (HR) children). However, little work has investigated gesture as a function of language ability, which varies greatly in this population. Aims: This longitudinal…

Video viewing can be a valuable resource to expose students to large quantities of input so they can improve their vocabulary and content comprehension. Most studies so far have used short clips and have not explored in much detail the effects of individual differences (IDs) such as aptitude, listening skills and vocabulary size. This paper aims…

The present study investigated a group of cognitive individual differences considered advantageous in second language learning and their role in language learning under implicit and explicit feedback conditions using both language awareness and language development measures. The study further investigated whether different types of awareness are…

Human behavior is not constant over the hours of the day, and there are considerable individual differences. Some people raise early and go to bed early and have their peek performance early in the day ("larks") while others tend to go to bed late and get up late and have their best performance later in the day ("owls"). In…

We report the first study on pronoun use by an under-studied research population, children with autism spectrum disorder (ASD) exposed to American Sign Language from birth by their deaf parents. Personal pronouns cause difficulties for hearing children with ASD, who sometimes reverse or avoid them. Unlike speech pronouns, sign pronouns are…

A large body studies into individual differences in second language learning has shown that success in second language learning is strongly affected by a set of relevant learner characteristics ranging from the age of onset to motivation, aptitude, and personality. Most studies have concentrated on a limited number of learner characteristics and…

Purpose: The purpose of this research forum article is to provide an overview of typical and atypical development of English as a second language (L2) and to present strategies for clinical assessment with English language learners (ELLs). Method: A review of studies examining the lexical, morphological, narrative, and verbal memory abilities of…

The current study longitudinally examined the influence of aptitude on second language (L2) pronunciation development when 40 first-year Japanese university students engaged in practice activities inside and outside English-as-a-Foreign-Language classrooms over one academic year. Spontaneous speech samples were elicited at the beginning, middle,…
