Formal language hierarchy describes levels of increasing syntactic complexity (adjacent dependencies, nonadjacent nested, nonadjacent crossed) of which the transcription into a hierarchy of cognitive complexity remains under debate. The cognitive foundations of formal language hierarchy have been contradicted by two types of evidence: First,…

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…

The effect of language aptitude on grammar attainment of second language learners with different ages of onset became one of the hot topics in the last decades. However, most previous studies were conducted in a second language context with inconsistent results, and few studies were conducted in a foreign language context. To fill this gap, the…

This study addresses the role of domain-general mechanisms in second-language learning and knowledge using an individual differences approach. We examine the predictive validity of implicit-statistical learning aptitude for implicit second-language knowledge. Participants (n = 131) completed a battery of four aptitude measures and nine grammar…

Purpose: We investigated the efficacy of "Story Champs" for improving oral language in third-grade Spanish-English bilingual children with developmental language disorder (DLD). Method: We implemented a concurrent multiple-baseline across-participants single-case design with four bilingual Spanish-English third-grade students with DLD.…

In this study, neural representation of adult second language (L2) speakers' implicit grammatical knowledge was investigated. Advanced L2 speakers of Japanese living in Japan, as well as L1 Japanese speakers, performed a word-monitoring task (proposed as an implicit knowledge test) in the MRI scanner. Behavioral measures were obtained from…

This study investigates the validity of syntactic priming as a measure of implicit language aptitude. Syntactic priming refers to the tendency to reproduce a linguistic structure due to a previous exposure to the structure. The validity of the construct was verified by collating evidence for divergent validity--whether it is dissociable from…

Nonverbal behavior can impact language proficiency scores in speaking tests, but there is little empirical information of the size or consistency of its effects or whether language proficiency may be a moderating variable. In this study, 100 novice raters watched and scored 30 recordings of test takers taking an international, high stakes…

While language aptitude and motivation are considered to be important contributors to second language (L2) attainment, two major gaps in the past research have been (1) a lack of nonlinear models stemming from a naive and tacit assumption that learning outcomes are linearly related to their predictors, and (2) a lack of unified and integrative…

Despite extensive use of online language learning during the pandemic of COVID, there is insufficient research on what factors influence students' foreign language achievements in online learning conditions. This article investigated the roles of language aptitude and online self-regulated learning in foreign language achievement in mainland…

Early conceptions of aptitude were concerned with explicit learning abilities in formal learning settings, which according to MLAT (Modern Language Aptitude Test) were measurable based on a phonemic coding ability, an inductive learning ability, an associative memory, and a grammatical sensitivity (Carroll, 1962). However, recent understanding on…

An enduring question is whether language learning aptitude is a stable trait or is one influenced by experience, such as living with two languages. We investigated aptitude in bilinguals and treated their bilingual experience as an aggregate of variables, focusing on how individual differences in (a) language experience variables of proficiency,…

"Second Language Acquisition -- Learning Theories and Recent Approaches" will aim to present the process of learning an additional language apart from one's native language. The process of understanding, writing, and speaking another language with fluency involves complex intellectual and emotional responses as well as continuous…

Over the last two decades, there has been an increasing interest in third language (L3) phonology (Cabrelli Amaro, 2012; Cabrelli Amaro & Wrembel, 2016). However, research so far has been primarily directed at specific stages of learning and has independently explored either production (e.g., Llama, Cardoso, & Collins, 2010; Llama &…

While aptitude has been seen to contribute to second language (L2) development, most studies have examined its contribution as a fixed trait, rather than viewing it as a dynamic, changing variable. There appears to have been little or no investigation of the role that aptitude plays in the development of L2 pragmatic ability. Therefore, this study…
