The current study set out to examine to what degree age of acquisition (AOA), defined as a learner's first intensive exposure to a second language (L2) environment, mediates the final state of postpubertal, spoken vocabulary attainment. In Study 1, spontaneous speech samples were elicited from experienced Japanese users of English (n = 41) using…

Joint attention is important for children's language development. We report two meta-analyses that demonstrate that the congruency in hearing status between parent and child affects the establishment and maintenance of joint attention. Dyads consisting of hearing parents and children with hearing loss, achieve fewer and briefer moments of joint…

The purpose of the study is to investigate the types of corrective feedback used by a Thai teacher with adult learners of different proficiency levels in speaking classes in order to facilitate students' language development, as it is an aspect language teachers need to be aware of when teaching speaking. Three different levels of speaking classes…

Recently reported links between rhythm and grammar processing have opened new perspectives for using rhythm in clinical interventions for children with developmental language disorder (DLD). Previous research using the rhythmic priming paradigm has shown improved performance on language tasks after regular rhythmic primes compared to control…

With the SWIRL method, K-12 teachers can give multilingual learners opportunities to engage in the five elements of speaking, writing, interacting, reading, and listening to English to become confident and proficient in English. The SWIRL Method provides research-based, time-tested, practical activities and strategies. Readers also get…

Purpose: This scoping review considers the acoustic features of a clear speech register directed to nonnative listeners known as foreigner-directed speech (FDS). We identify vowel hyperarticulation and low speech rate as the most representative acoustic features of FDS; other features, including wide pitch range and high intensity, are still under…

Certain structures are particularly challenging for children. Explanations of such challenges reference both grammatical development and processing capacities. This study concerns production-specific considerations. Sixteen adults and 72 children from ages 3;01 to 8;11 participated in an experiment designed to elicit imitation of one-, two-, and…

We used the elicited production task to explore the production of short and long passives in 15 Mandarin-speaking preschool children with Developmental Language Disorder (DLD; aged 4;2-5;11) in comparison with 15 Typically Developing Aged-matched (TDA) children (aged 4;3-5;8) and 15 Typically Developing Younger (TDY) children (aged 3;2-4;3). This…

The paper investigates a Hungarian-English bilingual child's Sarah's second language acquisition (SLA) with a special focus on how she integrated English (L2) into her speech to convey the intended meaning and negotiate the multiple identities she developed in her bilingualism in various social contexts. An ethnographic single-case study research…

The Discontinuity Model (DM) described in this article proposes that adults can learn part of L2 morphosyntax twice, in two different ways. The same item can be learned as the product of generation by a rule or as a modification of a template already stored in memory. These learning modalities, which are often seen as opposed in language theory,…

Word segmentation in L2 is not as optimal as in L1 because many, though not all, cues to signal word boundaries appear to be largely language-specific. Native English listeners use short-lag versus long-lag VOTs in segmenting pairs such as "Lou spills" versus "loose pills." Polish contrasts negative versus short-lag VOTs, so…

Many ancestral languages (AL) are at imminent risk of extinction due to societal changes that pressure minority communities to assimilate with dominant cultures and forego usage of their AL. This study aimed to encourage caregiver-child dyads to converse in Lazuri, an endangered AL in Rize, Turkey. Dyads (N = 59; child age M = 30.7 months, range…

Background: Multilingualism can bring about various positive outcomes to typically developing children. Its effect on children with language difficulties is not yet clear. Aim: The aim of this study was to examine the effects of multilingual learning as a medium of instruction (MOI) on first language (L1) acquisition of children with language…

Second language acquisition studies can contribute to the body of research on the influence of language on thought by examining cognitive change as a result of second language learning. We conducted a longitudinal study that examined how the acquisition of Spanish grammatical gender influences categorization in native English-speaking adults. We…

Purpose: This study examined whether English-only vocabulary instruction or English vocabulary instruction enhanced with Spanish bridging produced greater word learning in young Spanish-speaking children learning English during a storybook reading intervention while considering individual language characteristics. Method: Twenty-two…
