While studies have documented neural correlates of language delay in toddlers with developmental conditions, those at genetic risk for language delay, and those born premature, no studies have examined neural correlates in toddlers exhibiting early language delay without known aetiology. This study examines brain morphometry in toddlers with and…

Knowing how children become oriented to imaginary play can help educators in centres better support development. But how this begins in the first years of life is not well understood. How toddlers transform through their imagination concrete objects (such as play accessories, figurines, and books) to become props in play (placeholders and pivots)…

Executive functions (EFs) emerge in the first years of life and are essential for many areas of child development. However, intraindividual developmental trajectories of EF during toddlerhood and their associations with ongoing development of language skills remain poorly understood. The present three-wave study examined these trajectories and…

Perspective taking and cognitive flexibility are important abilities for navigating our everyday lives. In this longitudinal study with 108 children (61 girls, mostly White), we investigated the developmental relation between Level 1 perspective taking at 27 months of age and Level 2 perspective taking at 52 months of age as well as relations to…

STEM is not just about learning four discrete subject-specific content areas (McClure et al., 2017), but also an approach of higher order thinking (i.e., the ability to think critically, logically, and creatively, and solve problems; Baharin et al., 2018). In this article, the authors use STEM learning to describe children's learning about STEM,…

When children are aged around 2 years, many of the early foundations of mathematical skills are developing. Understanding this is important to shed light on theories of mathematical development. Nevertheless, little research has investigated 2-year-olds' early mathematical abilities, with most research focussing on either infants (aged 0-1 years)…

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…

We describe the development of 236 children with Angelman syndrome (AS) using the Bayley Scales of Infant and Toddler Development, Third Edition. Multilevel linear mixed modeling approaches were used to explore differences between molecular subtypes and over time. Individuals with AS continue to make slow gains in development through at least age…

In this longitudinal study, we investigated the factor structure and stability of early-life temperament in a German sample, using three measures developed within Rothbart's psychobiological approach. Temperament was measured using the Infant Behavior Questionnaire Revised (IBQ-R) at the ages of 6 and 12 months, the Early Childhood Behavior…

Inhibitory control (IC) is a core executive function integral to self-regulation and cognitive control, yet is itself multi-componential. Directed global inhibition entails stopping an action on demand. Competitive inhibition is engaged when an alternative response must also be produced. Related, but not an executive function, is…

In the field of educational robotics, it is important to understand the processes trough which child-robot interactions are established during play activities. In terms of socio-material characteristics, robots can vary widely, from more mechanical robots to more anthropomorphic ones. Research has shown that the degree of anthropomorphization of…

In recent years, and within the scope of moving towards more inclusive and democratic classrooms, some scholars have proposed developing approaches to Music Education that depart from sound and sounding phenomena as larger categories that might incorporate the diverse trajectories and life experiences of children. In accordance with this initial…

Can at-scale, government-implemented parent training programs improve parenting practices and child development outcomes? This article presents evidence on the effects of a low-cost, group-based early childhood education program that provided parent training and direct child stimulation in rural communities, evaluated in six Mexican states.…

Toddlerhood is a period of intensive and rapid socio-emotional development. The effects of different types of childcare settings on child development have been widely studied, but the results have often been contradictory. The aim of this study was to compare social competence and socio-emotional problems in two-year-old children (n = 1104; girls…

Maternal substance use and unpredictable maternal sensory signals may affect child development, but no studies have examined them together. We explored the unpredictability, frequency and duration of maternal sensory signals in 52 Caucasian mother-child dyads, 27 with and 25 without maternal substance use. We also examined the association between…
