The purpose of this preliminary study was to (a) examine relationships between the symbolic and language skills of a mixed (developmental language disordered [DLD] and typical language [TL]) Spanish-speaking sample; (b) describe gesture, play, and language skills of DLD and TL groups; (c) compare the development between groups; and (d) explore…

There is little evidence regarding the benefits of early center-based care attendance (before three years old) for child development and most studies have focused on developed countries. Addressing this gap, this study examines the relationship between center-based care attendance during toddler years and children's cognitive outcomes. Research…

Early trilingual development is an excellent testing ground for input reduction effects on acquisition outcomes. This article reports a study investigating input-outcome relations in a child Leo in Hong Kong, who was addressed to in Mandarin, Cantonese and later also in English by caretakers through 'one caretaker-one language' and 'one day-one…

In this study, the relationship between play, language skills and social competence is explored in a sample (n = 1005) of 33-month-old toddlers in a Norwegian early childhood education setting--Barnehages--based on two observational materials ("Tras" and "Alle med"). The study has two aims: (1) to investigate whether there is a…

Background: The aim of this project was to examine parent perceptions of potential communicative acts (PCAs) of children with, or at risk for, autism spectrum disorder (ASD). Methods: Participants were 6 males ranging from 17 to 30 months of age. Behaviours of interest were compared using parent report taken from the Inventory of Potential…

Social-emotional behavior in autism spectrum disorder (ASD) was examined among high-risk (HR; siblings of children diagnosed with ASD) and low-risk (LR; no family history of ASD) toddlers. Caregivers completed the Infant-Toddler Social Emotional Assessment (ITSEA) at 18 months, and blind diagnostic assessment for ASD was conducted at 36 months.…

The importance of early detection of autism spectrum disorder followed by early intervention is increasingly recognized. This quasi-experimental study evaluated the long-term effects of a program for the early detection of autism spectrum disorder (consisting of training of professionals and use of a referral protocol and screening instrument), to…

Amid growing controversy about the oft-cited "30-million-word gap," this investigation uses language data from five American communities across the socioeconomic spectrum to test, for the first time, Hart and Risley's (1995) claim that poor children hear 30 million fewer words than their middle-class counterparts during the early years…

Although the size of a child's vocabulary associates with language-processing skills, little is understood regarding how this relation emerges. This investigation asks whether and how the structure of vocabulary knowledge affects language processing in English-learning 24-month-old children (N = 32; 18 F, 14 M). Parental vocabulary report was used…

Natural disasters create immense challenges for young children by exposing them to a high degree of adversity. Interventions designed to build resilience in the aftermath of a natural disaster may help buffer the negative consequences of these adverse experiences. In this article, we report the results of our quasi-experimental evaluations of two…

This study examined the effect of a "ghost" demonstration on toddlers' imitation. In the "ghost" condition, virtual pieces moved to make a fish or boat puzzle. Fifty-two 2.5- and 3-year-olds were tested on a touchscreen (no transfer) or with 3D pieces (transfer); children tested with 3D pieces scored above a no demonstration…

Retrospective parental reports are common in the developmental science literature, but their validity has been questioned. We investigated the consistency of retrospective maternal recall by comparing original with retrospective maternal reports in three domains (maternal cognitions, mother-reported child and mother behaviors, and observed child…

Valid indigenous language assessments are needed to further our understanding of how children learn language around the world. We assessed the psychometric properties and performance of two caregiver-report measures of Wolof language skill (language milestones achieved and vocabulary knowledge) for 500 children (ages 0;4 to 2;6) living in rural…

Background: While considerable research exists on morphosyntax of school-age children with hearing impairment (HI), little is known about development of morphosyntax at younger ages. Some studies show that young children with HI have a delay in language abilities compared with children with normal hearing (NH); conversely, other studies show…

Within the United Kingdom, the importance of the appropriate parenting of children in their early years has received significant political support. However, it has been found that positive outcomes for young children, in terms of their present experience and future life chances, are often significantly weakened by the impact of poverty. A…
