Purpose: Late talkers (LTs) are a group of children who exhibit delays in language development without a known cause. Although a hallmark of LTs is a reduced expressive vocabulary, little is known about LTs' processing of semantic relations among words in their emerging vocabularies. This study uses an eye-tracking task to compare 2-year-old LTs'…

The purpose of this study was to examine the effects of extended vocabulary instruction on the expressive vocabulary of two third-grade students with vocabulary deficits. According to the Common Core State Standards Initiative (n.d.), students in third grade should be able to determine the meaning of unknown and multiple-meaning words and phrases…

The prevalence of late language emergence (LLE) in young children is high, comprising 10 to 20% of toddlers. Late language emergence refers to children who do not use at least 50 single words and 2-word phrases at the age of two. Current best practices for the under-three population with or at risk of having disabilities include the use of…

This research aims to investigate the impact of an early literacy programme called 'Dialog, Play and Tell--Early Literacy Skills Support Practices with Mother Involvement (DPT-ELP)' on the early literacy skills of socio-economically disadvantaged children. An interventional mixed research design was implemented with 13 children attending municipal…

One of the earliest sources of mathematical input arises in dyadic parent-child interactions. However, the emphasis has been on parental input only in speech and how input varies across different environmental and child-specific factors remains largely unexplored. Here, we investigated the relationship among parental math input modality and type,…

In early childhood, teacher-child conversations play a crucial role in fostering language learning, particularly vocabulary development. This research examines the mediating role of extended-child-talk between conversation-facilitating (CF) strategies and vocabulary learning in prekindergarten classrooms. Thirty-four teachers' book reading and…

A 7-year longitudinal study was conducted as part of the French national cohort ELFE (N = 1095). The aim was to identify how and why early language skills at 2 years might predict later literacy skills assessed successively at 5, 7, and 9 years (LitSk5y; 7y; 9y). Using one and the same model, we also examined the relations between literacy skills…

This study aimed to adapt and validate the Word Complexity Measure (WCM) for Persian-speaking toddlers. The WCM is a tool for assessing phonological complexity, originally proposed by Stoel-Gammon. The study was conducted in two phases: (1) adapting the WCM parameters to the Persian language and (2) conducting a validation study with 60…

The oral language proficiency of students in early education is crucial as teachers draw on this as a resource when developing literacy. There is a need to better understand what this oral language resource consists of at school entry, particularly the diversity amongst children so as to address inequalities. This article reports a study on a key…

Purpose: The aims of this study were to explore expressive vocabulary growth rates of children who are deaf or hard of hearing (DHH) during critical periods of brain development (birth to 3 years) as well as the factors that influence the trajectories of vocabulary growth in these early years of development. Of primary interest was the effect of…

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 study investigated the psycholinguistic and child-related variables that modulate vocabulary development and the so-called receptive-expressive gap in child L2 learners of Gaelic with English as their L1. In total, 50 6- to 8-year-old English-Gaelic bilingual children attending Gaelic-medium immersion education were administered the English…

Performing a stay in a country where the L2 is the official language can provide the perfect immersion for L2 development (traditional study abroad). In the case of English learners, internationalization and the role of English as a lingua franca make it unnecessary to perform the stay in an English-speaking country. Hence, an increasing number of…

This study examined the effectiveness of the "Thrive by Three" intervention for 1- to 3-year-old's language development. Data from 78 childcare centres, 187 toddler classrooms, and 1561 children (91.4% native Norwegian) were included. Results revealed that children in the intervention group had slightly steeper language development than…

This study examined the extent to which classroom quality (emotional and instructional climate) moderates the associations between teachers' beliefs about children, self-efficacy, and children's early language gains (receptive and expressive vocabulary). The study employed multilevel modeling with 606 preschool teachers and 2,536 preschool…
