Williams syndrome (WS) is a rare genetic syndrome. As with all rare syndromes, obtaining adequately powered sample sizes is a challenge. Here we present legacy data from seven UK labs, enabling the characterisation of cross-sectional and longitudinal developmental trajectories of verbal and non-verbal development in the largest sample of…

Early childhood education and care (ECEC) settings faced significant disruption during the COVID-19 pandemic, compromising the continuity, stability and quality of provision. Three years on from the first UK lockdown as pandemic-era preschoolers enter formal schooling, stakeholders are concerned about the impact of the disruption on children's…

Purpose: The purpose of this study was to investigate the relationship of the grunt vocalizations to cognitive and expressive language status in children with disabilities. Children with typical development produce communicative grunts at the onset of referential word production and comprehension at 14-16 months of age and continue to use this…

Background: Research trials of early intervention (EI) programs for children with autism spectrum disorder (ASD) generally demonstrate medium-to-large gains, on average, compared with "treatment as usual," in different developmental domains. Almost all children with ASD receive their treatment through community-based services, however,…

The purpose of this secondary analysis of state-collected data was to investigate developmental outcomes of preschool special education (PSE) services in a statewide cohort of participating children (n = 17,828). In line with federal performance indicators for Individuals with Disabilities Education Act early childhood programs, the outcome of…

The parent-child relationship has been presented as one of the most important contexts in the early stages of life, but not all caregivers provide an optimal environment for development. Some parental and environmental factors exert a particularly strong influence on development. Parental practices and socioeconomic status are the factors most…

In the United States, early intervention (EI) programs under Part C of the Individuals with Disabilities Education Act serve thousands of infants and toddlers with or at risk for developmental delays. Despite this, few studies have investigated the developmental progress and outcomes of children served, especially in relation to the heterogeneity…

During communication, conversational partners should offer as much information as is required and relevant. For instance, the statement "Some Xs Y" is infelicitous if one knows that all Xs Y. Do children understand the link between speaker knowledge and utterance strength? In Experiment 1, 5-year-olds (N = 32) but not 4-year-olds…

Objective: Our objective was to evaluate the efficacy of the Sitting Together and Reaching to Play (START-Play) intervention in young infants with neuromotor disorders. Method: This randomized controlled trial compared usual care-early intervention (UC-EI) with START-Play plus UC-EI. Analyses included 112 infants with motor delay (55 UC-EI, 57…

Research Findings: Kindergarten Entry Assessments (KEAs) -- assessment tools used at the beginning of kindergarten to provide educators with a snapshot of children's readiness for school -- are increasingly being adopted by states across the country. The purpose of this study is to examine the implementation of North Carolina's KEA through…

Play is never absent in human life, especially for children. The act of playing requires a game. Games can be divided into digital games and non-digital games. Digital games are games that utilise computers, mobile or handheld devices, or gaming console as playing platform while non-digital games may require physical contact and/or equipment which…

This list of tools was compiled to assist states and programs with identifying assessments that can be administered when the assessor cannot be in the room with the child. This is a list of screening tools that can be completed remotely when the practitioner cannot be in the room with the child. Screening tools assess the possibility of a…

Foetal growth restriction is associated with problems in neurocognitive development. In the present study, prospectively collected cohorts of foetal growth restricted (FGR) and appropriate for gestational age grown (AGA) children were examined at early school-age by using the Children's Communication Checklist-2 (CCC-2) to test the hypothesis that…

Research examining the effects of subsidized childcare prior to school entry for child development is inconsistent. This population-based study examines the relationship between two poverty levels (extreme poor and working poor) and children's developmental outcomes, as measured by the Early Development Instrument. It also determines the extent to…

This study is part of a larger longitudinal project with the aim of focusing early social interaction and development of mentalizing ability in 12 deaf infants, including the interaction between the infants and their deaf parents. The aim of the present paper is to describe early social interaction and moments of intersubjectivity between the deaf…
