Most second language acquisition (SLA) research has documented the processes involved in learning second/foreign languages, with few studies focusing on the durability of attained second language (L2) skills once instructed learners/users are no longer receiving formal instruction. The current study examines the effects of continued exposure and…

A strong predictor of children's language is performance on non-word repetition (NWR) tasks. However, the basis of this relationship remains unknown. Some suggest that NWR tasks measure phonological working memory, which then affects language growth. Others argue that children's knowledge of language/language experience affects NWR performance. A…

Which theoretical and empirical insights can inform language-in-education research that advances equitable and high-quality learning at school? In this three-part article, I first draw from various sources to foreground the urgent need to counteract linguicism and epistemic injustices and to commit to more just and rigorous scientific practices in…

The main objective of this Methods Showcase Article is to show how the technique of adaptive comparative judgment, coupled with a crowdsourcing approach, can offer practical solutions to reliability issues as well as to address the time and cost difficulties associated with a text-based approach to proficiency assessment in L2 research. We…

In this study, we investigated the direct and indirect associations of different cognitive-linguistic skills and Chinese reading comprehension in Hong Kong kindergarteners. We assessed 179 children's nonverbal IQ, cognitive-linguistic skills, word reading, listening comprehension, and reading comprehension. Results showed significant correlations…

After discussing key issues in the aptitude literature and presenting an updated, multicomponential model of cognitive language aptitude, we consider two analyses from a longitudinal investigation using aptitude to predict success in language learning. Aptitude is conceptualized as a special talent for learning languages and a ceiling on success.…

Verb-marking errors such as "she play football" and "daddy singing" are a hallmark feature of English-speaking children's speech. We investigated the proposal that these errors are input-driven errors of commission arising from the high relative frequency of subject + unmarked verb sequences in well-formed child-directed…

This study reports on the conceptualization of a new construct targeting the cross-disciplinary academic language skills most relevant to school reading comprehension, targeting the validation of the Core Academic Language Skills (CALS) Instrument, a novel assessment tool which measures this construct. Participants included Grade 4-8 monolingual…

This study examines the relationship between different types of language learning aptitude (measured via the LLAMA test) and adult second language (L2) learners' attainment in speech production in English-as-a-foreign-language (EFL) classrooms. Picture descriptions elicited from 50 Japanese EFL learners from varied proficiency levels were analyzed…

Most studies on the perception-production link have assumed a synchronous relationship according to which gains in perception transfer to production rapidly and efficiently. However, time-lagged and asymptotic relationships are also possible, where perception would guide production at a later stage or production would improve only once perception…

This study investigated first (L1) and second (L2) language acquisition in two age-matched groups of 2- to 6-year-old kindergarten children over the course of 2.5 years. The immersion group participated in a partial English immersion program whereas the conventional instruction group received a conventional L2 course (30 minutes per week); the…

The linguistic interdependence hypothesis states that the development of skills in a second language (L2) partly depends on the skill level in the first language (L1). It has been suggested that the theory lacked attention for differential interdependence. In this study we test what we call the hypothesis of context-dependent linguistic…

Foreign language education has now been implemented at the elementary school level across Europe, and early foreign language education has gained traction following language policies set by the European Commission. The long-term effects of an early start, however, have not received ample scientific scrutiny. The present study assessed early…

In this article we report on early rhythmic discrimination performance of children who participated in a longitudinal study following children from birth to their 6th year of life. Thirty-four children including 8 children with a family risk for developmental language impairment were tested on the discrimination of trochaic and iambic disyllabic…

Listening comprehension plays a key role in language acquisition, yet little is known about the variables that contribute to the development of second language (L2) listening ability. This study sought to obtain empirical evidence for the impact of some of the learner variables and the degree to which they might predict success in L2 listening.…
