Shared book reading is a well-established vehicle for promoting child language and early development. Yet, existing shared reading interventions have primarily included only children age 3 years and older and high quality dialogic strategies have been less systematically applied for infants and toddlers. To address this gap, we have developed a…

Worldwide, a large number of infants, toddlers, and preschoolers are enroled in formal non-parental early childhood education or care (ECEC). Theoretically, lower adult/child ratios (fewer children per adult) and smaller group sizes are hypothesised to be associated with positive child outcomes in ECEC. A lower adult/child ratio and a smaller…

Sustained shared thinking dialogues which focus on teacher talk with preschool learners have long been considered an important route to learning progression. Toddlers, however, seldom engage in dialogues through talk alone, and their encounters are often fleeting. As a consequence, they are often positioned on the periphery of learning dialogues…

Purpose: Speech sound production intervention in early childhood is relatively rare despite empirical and theoretical support for providing this type of targeted therapy for toddlers. Challenges perpetuate the present clinical condition including those related to treatment decision making (e.g., intervention approach). Method: Although there are…

Background: Spontaneous upper extremity movements in infancy provide insight on neuromotor development. Spatiotemporal kinematics have been used to evaluate typical development of reaching, a foundational motor skill in infancy. This study evaluates the relationship between spontaneous upper extremity movements, not elicited by a toy, and motor…

Purpose: This review article summarizes programmatic research on sentence diversity in toddlers developing language typically and explores developmental patterns of sentence diversity in toddlers at risk for specific language impairment. Method: The first half of this review article presents a sentence-focused approach to language assessment and…

Little is known about the influence of social context on children's event memory. Across four studies, we examined whether learning that could occur in the absence of a person was more robust when a person was present. Three-year-old children (N = 125) viewed sequential events that either included or excluded an acting agent. In Experiment 1,…

Purpose: This study examines the influence of lexical and phonological factors on expressive lexicon size in 40 French-speaking children tested longitudinally from 22 to 48 months. The factors include those based on the lexical and phonological properties of words in the children's lexicons (phonetic complexity, word length, neighborhood density…

Eye-tracking research on social attention in infants and toddlers has included heterogeneous stimuli and analysis techniques. This allows measurement of looking to inner facial features under diverse conditions but restricts across-study comparisons. Eye-mouth index (EMI) is a measure of relative preference for looking to the eyes or mouth,…

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…

The present research studied children in the second year of life (N = 29, M[subscript age] = 21.14 months, SD = 2.64 months) using experimental manipulations within and between subjects to show that responsive parental influence helps children have more frequent sustained object holds with fewer switches between objects compared to when parents…

Prenatal folate and vitamin B[subscript 12] status have been linked to child neuropsychological development, but less is known about maternal genetic influences on this association. We conducted an exploratory longitudinal study of 181 mother--child pairs to assess whether maternal MTHFR 677C>T genotype modifies the association between maternal…

Background: Children with a significant cognitive and motor developmental delay are pre-symbolic communicators. The primary aim of this study was to reveal the variability within the communicative functioning of this group of children in terms of communication level, the reasons to communicate and behavioural expressions. Methods: Twenty-six…

Object exploration is considered a driver of motor, cognitive, and social development. However, little is known about how early childhood education and care settings facilitate object exploration. This study examined if children's exploration of objects during free play was facilitated by the use of particular spatial components (floor, tables,…

Early intervention supports infants and toddlers with confirmed or suspected autism spectrum disorder (ASD) in achieving optimal outcomes, and caregiver-implemented NDBIs are recommended as a developmentally appropriate intervention approach for very young children and their families. Research highlights discrepancies between early…
