Visual working memory (VWM) capacity has been studied extensively in adults, and methodological advances have enabled researchers to probe capacity limits in infancy using a preferential looking paradigm. Evidence suggests that capacity increases rapidly between 6 and 10 months of age. To understand how the VWM system develops, we must understand…

Objective: The onset of autism is usually conceptualized as occurring in one of two patterns, early onset or regressive. This study examined the number and shape of trajectories of symptom onset evident in coded home movies of children with autism and examined their correspondence with parent report of onset. Method: Four social-communicative…

In this article the author describes challenges associated with integrating physiological measures of stress into developmental research, especially in the domains of memory and cognition. An initial critical challenge concerns how to define stress, which can refer to one or a series of events, a response, the consequence of that response, an…

Aim: The aim of this study was to determine population-specific developmental milestones for independence in self-care, mobility, and social cognitive skills in children with achondroplasia, the most common skeletal dysplasia. Methods: Population-based recruitment from October 2008 to October 2010 identified 44 Australian children with…

This study examined reciprocal relationships between adolescents' perceptions of parental nurturance and two types of adolescent aggressive behaviors (indirect and direct aggression) using a transactional model. Three waves of longitudinal data were drawn from the Canadian National Longitudinal Survey of Children and Youth. The sample included…

Objective: Child protection, as primarily applied toward narrow corrective intervention, has been judged to be inadequate in dealing with the wide variety of forms and levels of physical, psychological and sexual violence to which children are subjected throughout the world. Concern about this state of affairs has grown as a part of a global…

In this study, the authors assessed children's ability to use information overheard in other people's conversations to judge the reality status of a novel entity. Three- to 9-year-old children (N = 101) watched video clips in which two adults conversed casually about a novel being. Videos contained statements that explicitly denied, explicitly…

Research connecting children's understanding of mental states to their peer relations at school remains scarce. Previous work by the authors demonstrated that children's understanding of mental states in the context of a faux pas--a social blunder involving unintentional insult--is associated with concurrent peer rejection. The present report…

This article revisits radical playgrounds of the past to offer a productive dialogue with recent debates on how child environments can foster citizenship and community. Joan Littlewood's playground projects are familiar examples of theatre techniques being applied to develop children's sense of belonging in a city. This essay considers the less…

No evidence had been provided so far of newborns' capacity to give a matching response to 2D stimuli. We report evidence from 18 newborns who were presented with three types of stimuli on a 2D screen. The stimuli were video-recorded displays of tongue protrusion shown by: (a) a human face, (b) a human tongue from a disembodied mouth, and (c) an…

It is not known whether reproductive factors early in the mother's life influence risk of autism spectrum disorders (ASD). We assessed maternal age at menarche, menstrual cycle characteristics during adolescence, oral contraceptive use prior to first birth, body shape, and body mass index (BMI) in association with ASD using binomial regression in…

Susan Isaacs made a significant impression on the world of early childhood education during the first half of the twentieth century. She ranks alongside Froebel and Dewey, as one of the pioneers of child-centred education. As Jody Hall has written, "the life, work and legacy of Isaacs serve as a witness to the value of the curiosity of children."…

This paper makes a fundamentally simple line of empirically supported argumentation. The increasing demands for high level student learning can best be achieved by the use of the substantive research evidence of the past decade demonstrating that developmentally oriented instruction facilitates academic, behavioral, and social performance. Most…

In 2001, The Pew Charitable Trusts learned of an important strategy that could dramatically improve children's success but had been largely overlooked by policy makers--high-quality early education programs in the years just before kindergarten. Soon after, it launched a new campaign to highlight the evidence and advance policies at the state and…

"Research Connections" conducted a comprehensive search of its collection for resources focused on early mathematics. This Key Topic Resource List includes an overview of the early mathematics literature, as well as a listing of selected resources on the topic. Search results are grouped into five broad areas: (1) Programs and…
