Preventative parent-coaching programs can improve early interaction quality, language skills, and academic outcomes for children experiencing economic adversity. Using a community-based participatory research framework, we piloted Duet, a preventative, parent-implemented, early language intervention. We assigned home visitors to provide Duet or…

As written language contains more complex syntax than spoken language, exposure to written language provides opportunities for children to experience language input different from everyday speech. We investigated the distribution and nature of relative clauses in three large developmental corpora: one of child-directed speech (targeted at…

Learning new words and, subsequently, a lexicon, is a time-extended process requiring encoding of word-referent pairs, retention of that information, and generalization to other exemplars of the category. Some children, however, fail in one or more of these processes resulting in language delays. The present study examines the abilities of…

This study investigates how Japanese-speaking children learn interactional dependencies in conversations that determine the use of "un," a token typically used as a positive response for yes-no questions, backchannel, and acknowledgement. We hypothesise that children learn to produce un appropriately by recognising different types of…

A growing body of research suggests that individual variation in young children's word comprehension (indexed by response times and accuracy) is structured and meaningful. In this paper, we assess how children's word comprehension correlates with three factors: socio-economic status (indexed by maternal education), lingual status (based on…

Purpose: Our goal is to understand how the different types of plural marking are understood and processed by children with cochlear implants (CIs): (a) how does salience affect the processing of plural marking, (b) how is this processing affected by the incomplete signal provided by the CIs, and (c) is it linked to individual factors such as…

Purpose: We examined the properties of mean length of utterance (MLU) in Czech, a morphologically complex Slavic language. We compared the scores of MLU calculated in different units and based on different sample lengths and assessed its validity against another transcript and test-based measures. Method: One hundred nine children were recorded…

This research applies interactional sociolinguistics within a family language policy framework to investigate how social structures and institutional discourses outside the home trickle into daily mundane activities within a Malay-English bilingual family in Singapore. Drawing upon ethnographic interviews and naturally-occurring interactions at…

This case study examines emergent, evolving language ideologies of a trilingual child, from age 3-7, who was simultaneously acquiring two heritage languages, Korean and Farsi, as well as English in the United States. A qualitative analysis of the child's conversations in a naturally occurring home context extends the literature centered on the…

This study examines the extent to which verb argument construction (VAC) based indices of syntactic complexity could predict four different writing task conditions: a simple task with no repetition (S + NR), a simple task with repetition (S + R), a complex task with no repetition (C + NR), and a complex task with repetition (C + R). Ninety-six…

The aim of this study was to explore the strategies that speech-language pathologists (SLPs) use during their linguistic interventions on children with cochlear implants (CIs). The sample comprised 7 SLPs in interactions with 62 children, 31 with CIs and 31 with typical hearing (TH), from 5 to 7 years of age. Two linguistic activities were used:…

This research explores into the issues faced by heritage language speakers and learners, a topic gaining increasing relevance as millions of individuals reside outside their country or region of birth for various reasons. The primary objective of this study is to investigate the experiences and proficiency of the heritage language among ethnic…

The purpose of this study was to investigate the extent to which the efficacy of the Teaching Early Literacy and Language (TELL) curriculum package for low-income preschoolers was impacted by participant characteristics and variables associated with implementation. In a follow-up to a randomized controlled trial (Gray et al., 2024), data was…

Deaf education officially began in Portugal in 1823, with Pedro Aron Borg, at the invitation of D. João VI and his daughter, D. Isabel. In Brazil, it began in 1857, when Édouard Adolfo Huet Merlo founded the first institution, with the consent of D. Pedro II. The Royal Institute for the Deaf-Mute and the Blind in Lisbon and the Imperial Institute…

Aspect markers (AMs), temporal adverbs (TAs) and temporal nouns (TNs) are used by young Mandarin-speaking children to express time. However, the factors that affect the relative acquisition trajectories of these categories remains unclear. Accordingly, this study adopts Weist's time-concept model to examine the patterns of acquisition between and…
