Identifying infants at elevated likelihood for autism and other developmental differences in the first year of life remains a significant challenge. This study explored associations between behavioral differences in infancy and developmental outcomes in toddlerhood. We conducted a secondary data analysis of 256 infants with an older autistic…

To date, virtually no studies have examined toddlers' non-response in developmental tasks. This study investigates data from 3667 toddlers to address (1) whether two aspects of non-response (completion and engagement) are separable, (2) how stable these aspects are from ages two to three, (3) how non-response relates to background characteristics,…

The development of children's future-oriented cognition has become a popular research topic in the past two decades. Much of this research focuses on the preschool and middle childhood years, but very little is known about the future-oriented cognitive abilities of toddlers and young preschoolers. The present study investigated the emergence of…

Over the past 20+ years, researchers have worked toward identifying early behavioral predictors of autism spectrum disorder (ASD) and developing observation-based screeners to supplement existing parent-report methods. This study is a follow-up, 3 to 8 years later, with parents/caregivers of 57 children previously enrolled in a U.S.…

Children vary in how sensitive they are to experiences, with consequences for their developmental outcomes. In the current study, we investigated how behavioral sensitivity at age 3 years predicts mental health in middle childhood. Using a novel repeated measures design, we calculated child sensitivity to multiple psychological and social…

The aim of our study is to describe the neuromotor development of preterm and low birth weight infants at 1 and 2 years of corrected age, and to examine the extent to which perinatal, neonatal, socio-demographic, and neuromotor development indices measured at the age of 1 are able to predict infants' development indices at the age of 2. Our sample…

Adults' behaviour in interactions with children is assumed to influence children's playfulness. However, little is known about how the quality of teacher-child interaction in early childhood education and care affects the development of children's playfulness, although the interaction quality has been identified as a strong predictor of children's…

Infants can help and share in the second year of life. However, there is limited knowledge as to variability in these behaviors as a function of target (e.g., caregiver vs. unfamiliar adult) and the influence of caregiver support on infant prosocial behavior. Infants (N = 268, 124 female) at 1-2 years of age (M = 1.47, SD = 0.27) and again at 2-3…

How do children construct a concept of natural numbers? Past research addressing this question has mainly focused on understanding how children come to acquire the cardinality principle. However, at that point children already understand the first number words and have a rudimentary natural number concept in place. The question therefore remains;…

This study estimates the effect of physical punishment on the cognitive development of 1,167 low-income Colombian children (M[subscript age] = 17.8 months old) using 3 analytic strategies: lagged-dependent variables, a difference-in-differences-like approach (DD), and a novel strategy combining matching with a DD-like approach. Across approaches,…

Parental engagement in stimulating activities and support in both formal and informal learning environments are important for early childhood development. However, little is known about how parental mental health and beliefs about early childhood development shape such investments. We draw on a sample of young children and their primary caregiver…

Theoretical models posit real-time bidirectional processes between parents and children as integral to child development, yet few studies have examined such processes. In this study, cross-lagged autoregressive latent growth models were used to assess the dynamic organization of mother and toddler behavior across a snack-delay task. Maternal…

Few studies have investigated associations of milestone development in early childhood with intelligence in adulthood in typically developing children. The current study is an extension of 2 previous studies on smaller samples and investigated associations of age at attainment of 32 developmental milestones attained between 0 and 3 years of age…

The purpose of the study was to evaluate fine- and gross-motor development and basic cognitive skills in 3-18 month-olds in relation to home factors, age and weight. Three hundred and seventy mother-child dyads were recruited. For age, two groups were analyzed: 3-11 months and 12-18 months. Motor and basic cognitive skills were assessed using the…

There is evidence that parents could influence the development of their children's effortful control in infancy through social interaction. Playful interactions in infancy often involve scaffolding - i.e. the parental provision of support and modelling for problem solving and learning during play. However, previous research has found little…
