The present study explored the association between the structural quality of child care, caregivers' sensitive responsiveness, children's involvement in play and activity in the setting, and children's expression of aggression. Eighty-four early childhood care settings were classified into either high (29) or low structural quality (55) based on…

Language development plays a pivotal role in a child's cognitive and overall growth, progressing through identifiable stages that ultimately lead to adult communication. It serves as a significant indicator of a child's intellectual and overall development. This study aims to explore the impact of daily technology use on children's language…

Research on the early lexical-semantic system has described how toddlers organize word representations based on semantic and phonological features. This study is a longitudinal investigation of the development of this organization during infancy. Middle-high socioeconomic status Mexican toddlers (n = 28, 15 female) were presented with a…

We examined the evolution of social pretend play in toddlers and tested whether children's age, gender, and language abilities were associated with changes in social pretend play over time. We employed a unique observational data set that followed 28 children (M[subscript age] = 27 months old; 57% boys) with each of two unfamiliar peers over 18…

The purpose of this article is to present a theory-driven blended intervention model that integrates evidence-based interventions to support language and social development of young children. We (1) provide an overview of practices that are designed to support language and social-emotional development, (2) present a theory of change model that…

There is a well-documented link between bilingual language development and the relative amounts of exposure to each language. Less is known about the role of quality indicators of caregiver-child interactions in bilingual homes, including caregiver input diversity, warmth and sensitivity. This longitudinal study examines the relation between…

Background: A wealth of evidence supports the important role high-quality parent-child interactions play in children's early language acquisition. However, the impact on later language outcomes remains unclear. Aims: To examine the associations between responsive parental behaviours across the early years and child language outcomes at age 7 years…

Part C Early Intervention (EI) systems are an entry point to services for autistic toddlers and can be leveraged to facilitate access to autism evidence-based practices (EBPs). However, EI systems are complex and limited research has examined how an EI system's infrastructure (i.e. system-level factors) impacts the adoption and implementation of…

The choice of cortisol sampling times in early childhood studies varies widely. Given that recommendations on sampling protocols are largely based on adults, the present study aimed to broaden current knowledge by examining how reliably cortisol measures obtained at different daytimes would reveal between-individual differences in toddlers'…

The twofold aim of the present study was to examine the relationship between toddlers' physical and social spontaneity, as well as to investigate the interaction effects of gender, geographical background, and mother's occupational status on preschoolers' playfulness. Participants were 650 preschool children (353 boys, 297 girls), attending…

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…

This investigation examined the existence of interconnectedness between developing linguistic subsystems. Spontaneous speech samples were collected from 31 typically-developing Greek-speaking toddlers across two age levels, at 28 and 36 months. Correlational analyses were performed synchronically and predictively, revealing significant positive…

Play is central to children's learning and development in the early years, including the learning of mathematics. The aim of the present study was to explore how play skills are related to mathematical skills in toddlers by examining the correlations between different kinds of play skills and mathematical skills, and how level of play skills is…

This study examined the development of caregiver mind-mindedness--defined as the propensity to see one's child as an agent with an independent mind--across the first 1,000 days of life. At four timepoints (i.e., third trimester of pregnancy, 4, 14, and 24 months postpartum), 384 first-time mothers (M[subscript age] = 32.55, SD = 3.63 years) and…
