To explore the different developmental trajectories of social-communicative skills in children with autism and typically developing infants, two longitudinal studies were conducted. In Study 1, we examined the developmental sequence of social-communicative skills in 26 typically developing infants when they were 9 months old and reexamined them…

How objects are held determines how they are seen, and may thereby play an important developmental role in building visual object representations. Previous research suggests that toddlers, like adults, show themselves a disproportionate number of planar object views--that is, views in which the objects' axes of elongation are perpendicular or…

To what extent do toddlers have shared vocabularies? We examined CDI data collected from 14,607 infants and toddlers in five countries and measured the amount of variability between individual lexicons during development for both comprehension and production. Early lexicons are highly overlapping. However, beyond 100 words, toddlers share more…

We tested the hypothesis that developmental precursors to aggression are apparent in infancy. Up to three informants rated 301 firstborn infants for early signs of anger, hitting and biting; 279 (93%) were assessed again as toddlers. Informants' ratings were validated by direct observation at both ages. The precursor behaviours were…

The aim of this study was to examine the association of breastfeeding practices with the growth trajectories of children's cognitive development. We used data from the Child Development Supplement (CDS) of the Panel Study of Income Dynamics (PSID) with variables on presence and duration of breastfeeding and standardized test scores obtained…

In this article I discuss children's everyday uses of recorded music (such as CDs, Mp3-files) in the light of sociological notions of "children" and "childhood". The discussion provides perspectives on musical engagement and musicality that supplement perspectives within developmental psychology. The study is based on…

In a wide-ranging essay that reviews the major theories of plays and relates them to significant notions of the self, the author addresses the question of why we play. He does so to argue that play is a biologically driven project of self-understanding and self-realization, one that humans--although they also share the experience with other…

Scholars conventionally find play difficult to define because the concept is complex and ambiguous. The author proffers a definition of play that takes into consideration its dynamic character, posits six basic elements of play (anticipation, surprise, pleasure, understanding, strength, and poise), and explores some of their emotional, physical,…

In this article, the author synthesizes research from several disciplines to shed light on play's central role in healthy development. Gordon builds on research in attachment theory that correlates secure attachment in infancy with adult well-being to demonstrate how playfulness might be a lifelong outcome of secure attachment and a primary…

In the majority of states using Quality Rating and Improvement Systems (QRIS) to improve children's school readiness, the Early Childhood Environmental Rating Scale-Revised (ECERS-R) is a core assessment of preschool program quality and is central to QRIS metrics and incentive structures. The present study utilizes nationally representative…

This article addresses a question that is of key importance in preparing early childhood personnel, especially those in inclusive environments: "How do we teach in ways that we want our students to teach?" There is an emphasis on developing a "community of practice" where professionals can share their work-related concerns and…

This study highlights the importance of mentorship focused on reflective practice during preservice teacher education and early years of teaching. Thoughtful reflection about teaching practices during early years of teaching is critical in preparing teachers for a child-centered curriculum. To successfully distinguish between teacher-directed and…

Throughout its history, the ecology of the picturebook has been impacted by various social and cultural changes. Postmodernism is one perspective, among other conceptual and theoretical frameworks, that has been proposed to explain some of the fundamental changes evident in many contemporary picturebooks. A review of the literature (Pantaleo &…

Recent Illinois legislation requires school principals in the state to be qualified to provide school leadership for children from preschool to grade twelve instead of kindergarten to grade twelve. Illinois is the first state to make such a change and may well serve as a model for change in school leadership preparation on a national level. The…

Despite consensus in the developmental literature regarding the role of executive function (EF) skills in supporting the development of language skills during the preschool years, we know relatively little about the associations between EF skills, including all EF components, and vocabulary skills among preschool-aged children. In this paper, we…
