Inconsistent findings regarding sex differences in cognition have been found in people with autism spectrum disorder (ASD). This study evaluated sex differences in cognitive-developmental functioning in a large clinical sample of young children diagnosed with ASD. The sample included children 18-68 months of age who received the Mullen Scales of…

This longitudinal study examines change in maternal interaction strategies in Taiwanese mothers across time, and the synchronic and diachronic relationships between maternal interaction strategies and children's language and early literacy skills. Forty-two mother-child dyads participated in this study. Their interactions during joint book-reading…

Although symptoms of autism are present early in life and early diagnosis can lead to better outcomes, there is a dearth of validated caregiver-report interviews designed for children under the age of 3 years. We developed the Toddler Autism Symptom Inventory, a semi-structured interview designed to assess the presence and absence of skills and…

Background: There is empirical evidence that a developmental language disorder (DLD) in early childhood leads to behaviour problems. However, it is still not clear how changes in language proficiency in these children influence the presence of behaviour problems. Aims: The aim of this study is to examine if changes in language proficiency are…

Purpose: Fathers play a critical but underresearched role in their children's cognitive and linguistic development. Focusing on two-parent families with a mother and a father, the present longitudinal study explores the amount of paternal input infants hear during the first 2 years of life, how this input changes over time, and how it relates to…

Assessing children's working memory capacity (WMC) can be challenging for a variety of reasons, including the rapid increase in WMC across early childhood. Here, we developed and piloted an adapted WMC task, which involved minimal equipment, could be performed rapidly, and did not rely on verbal production ability (to facilitate the use of the…

Introduction: The main focus of early intervention is to strengthen the interaction of parents with young children with disabilities, and to ensure that parents become active participants in the development and education of their children. The purpose of this study is to examine the effectiveness of an Early Intervention Program based on…

This study investigated whether we can find reliable comprehension-to-production syntactic priming effects in children aged 2;0 to 2;11 and how phonological working memory and sentence production skills relate to the syntactic priming process. A finding of reliable syntactic priming effects would provide strong evidence that children's syntactic…

ZERO TO THREE and Los Angeles County Department of Mental Health (LACDMH) collaborated and contracted to provide official DC:0-5[TM] clinical training and foundational infant and early childhood mental health training to clinicians from Los Angeles (LA) County, California, over the course of 3 years.

The "DC:0-5[TM]: Diagnostic Classification of Mental Health and Developmental Disorders of Infancy and Early Childhood" (DC:0-5) includes significant revisions, making it a substantially different diagnostic framework from its predecessor, DC:0-3R. The Nordic countries have a long history of using the DC system. The Nordic DC:0-5…

The Recipe 4 Success preventive intervention targeted multiple factors critical to the health and well-being of toddlers living in poverty. This randomized controlled trial, which was embedded within Early Head Start home visits for 12 weeks, included 242 racially and ethnically diverse families (51% girls; toddler mean age = 2.58 years; data…

There is scant empirical work on associations between current and past cannabis use in parents of young children. As recreational cannabis use is now legal in nearly half of states in the U.S., cannabis use is becoming more ubiquitous. In the current study, parents of toddler and pre-school age children were randomly assigned to participate in an…

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…

In this article, we present an analysis of the complexity of grammatical constraints and their impact on early language acquisition of inflectional morphemes in Malayalam. We use the natural speech production data of two monolingual children acquiring Malayalam between the ages 1;9-2;10 and 2;3-3;0 and three bilingual children acquiring…

The separation of young children from their families for most of their awake hours, and the specific segregation of children by discrete chronological age through classrooms and grade levels, is a relatively new phenomenon in the history of human society. Such settler colonial constructs continue to influence early learning design, policy and…
