The present paper aims to investigate the interplay of lexical and grammatical development in school-aged Greek-Albanian bilingual children by providing evidence both from majority, Greek, and heritage, Albanian. To this end, 47 8 to 10-year-old bilingual children were tested by means of expressive vocabulary tests in Greek and in Albanian, while…

This article presents a cross-cultural comparison of the size and composition of the expressive vocabulary of young children speaking two dialectal varieties of South American Spanish. Ninety-one Peruvian and 91 Argentinian toddlers (mean age: 22.5 months), matched on gender, age and maternal education, were assessed through the respective…

This research aims to improve the vocabulary knowledge of Thai EFL students by using audio-visual aids as instructional tools. Hopefully, this study serves as an initial foundation to develop students' vocabulary knowledge and benefit the pedagogical development in Thailand. Consequently, this research aimed to explore the effectiveness of…

This article aims to uncover how alignment affects second language (L2) vocabulary acquisition by Chinese-speaking learners of English as they interact with various interaction loads (i.e. input text, peers and video). It also explores how tasks with varying interactional intensity in relation to the interaction loads influence the alignment…

While it is established that parental "wh"-questions, as a high-quality language input, are associated with child language outcome, less is known about the role of children's "wh"-questions in their language development. This study examines whether children's "wh"-questions during a dinnertime conversation are…

Specific features of adult linguistic input may play a larger, or smaller role, at different child ages, across different language outcomes, in different cohorts. This prospective, longitudinal study explored associations between the quantity and quality (i.e. diversity and responsiveness) of maternal linguistic input and child language. This…

Purpose: We report on a replicated single-case design study that measured the feasibility of an expressive vocabulary intervention for three Cantonese-speaking toddlers with small expressive lexicons relative to their age. The aim was to assess the cross-cultural and cross-linguistic feasibility of an intervention method developed for…

Children learn words by listening to caregivers, and the quantity and quality of early language input predict later language development. Recent research suggests that word recognition efficiency may influence the relationship between input and vocabulary growth. We asked whether language input and lexical processing at 28-39 months predicted…

Parent language input is a well-established predictor of child language development. Multisensory attention skills (MASks; intersensory matching, shifting and sustaining attention to audiovisual speech) are also known to be foundations for language development. However, due to a lack of appropriate measures, individual differences in these skills…

Language researchers and teachers have long been interested in the timing of learning, and the distributed practice effect, whereby greater inter-session intervals result in longer retention, is well-known (Kim & Webb, 2022). Many L2 studies have focused on the intentional learning of lexis (Edmonds, Gerbier, Palasis, & Whyte, 2021),…

The United States has witnessed a rise in dual language immersion (DLI) programs in recent years, with instruction delivered both in English, the majority language spoken in the wider society, and in another language, often referred to as the partner or minority language. But while accountability mandates have focused on students' performance in…

Lexical development of bilingual children is influenced by a number of input factors. In the present study, early lexical skills of 25-month old children growing up with Turkish and German were assessed. Parents of 92 children filled out a newly developed list for productive Turkish vocabulary, as well as a vocabulary list for German. A parental…

The unique relation of language use (i.e., output) to language growth was investigated for forty-seven 30-month-old Spanish-English bilingual children (27 girls, 20 boys) whose choices of which language to speak resulted in their levels of English output differing from their levels of English input. English expressive vocabularies and receptive…

Studies of phonological development that combine speech-processing experiments with observation and analysis of production remain rare, although production experience is necessarily relevant to developmental advance. Here we focus on three proposals regarding the relationship of production to word learning: (1) "Articulatory filter": The…

This study investigated how forty-six mothers modified their talk about familiar and unfamiliar nouns and verbs when interacting with their children with Down Syndrome (DS), language impairment (LI), or typical development (TD). Children (MLUs < 2·7) were group-matched on expressive vocabulary size. Mother-child dyads were recorded playing with…
