Infants' responses to typical and scrambled human body shapes were assessed in relation to the realism of the human body stimuli presented. In four separate experiments, infants were familiarized to typical human bodies and then shown a series of scrambled human bodies on the test. Looking behaviour was assessed in response to a range of different…

The sensitivity of size perception to context has been used to distinguish between "vision for action" and "vision for perception", and to study cultural, psychopathological, and developmental differences in perception. The status of that evidence is much debated, however. Here we use a rigorous double dissociation paradigm based on the Ebbinghaus…

This study examines how spontaneous interests in people and in objects relate to joint engagement in typically developing toddlers and young children with autism or Down syndrome. Ratings of interests were made repeatedly during intermissions in a laboratory-based protocol focused on caregiver-child interactions. Interests were moderated by…

For some time now, questions have been asked about the impact of television and video materials on the cognitive and social development of preschoolers and older children. More recently, these same questions have been asked in relation to the extensive exposure to these media that infants and toddlers are currently experiencing. To answer these…

The relation between children's mental state knowledge and metaknowledge about reading was examined in 2 studies. In Study 1, 196 children (mean age = 9 years) were tested for verbal ability (VA), metaknowledge about reading, and mental state words in a story task. In Study 2, the results of Study 1 were extended by using a cross-lagged design and…

In studies of child development, the combined effect of multiple risks acting in unison has been represented in a variety of ways. This investigation builds upon this preceding work and presents a new procedure for capturing the combined effect of multiple risks. A representative sample of 2,899 British children had their cognitive development…

There is rising interest in identifying precursors to bipolar disorder symptoms, including thought disorder. Thought disorder is identified in adults through self-report and in school-aged children through parent report and child story-telling. This study is an exploration to determine if preschoolers with mood dysregulation have evidence of…

The term "representational momentum" (RM) refers to the idea that our memory representations for moving objects incorporate information about movement--a fact that can lead us to make errors when judging an object's location (the RM effect). In this study, we explored the RM effect in a sample of children born very prematurely and a sample born at…

This study examined the developing object knowledge of infants through their visual anticipation of action targets during action observation. Infants (6, 8, 12, 14, and 16 months) and adults watched short movies of a person using 3 different everyday objects. Participants were presented with objects being brought either to a correct or to an…

Two humanist, critical approaches--those of Dorothy Dinnerstein and Immanuel Kant--are summarized, compared, and employed to critique gender bias in science education. The value of Dinnerstein's approach lies in her way of seeing conventional "masculinity" and conventional "femininity" as developing in relation to each other from early childhood.…

Pregnancy and early motherhood involve uncertainty and change, which can evoke mental health problems. We identified maternal mental health trajectories in pre- and postnatal period, and examined their association with later child mental health and development. Finnish mothers reported psychological distress (General Health Questionnaire [GHQ-36])…

The transition to adulthood is characterised by both great potential for positive change and a relatively high incidence of problem outcomes. A multidimensional model of positive development during the transition to adulthood (at 19-20 years) has recently been proposed. However, an unresolved question regarding the nature of positive development…

The goals of the Head Start Impact Study (HSIS) are to: (1) determine the impacts of Head Start on children's school readiness and parental practices that support children's development; and (2) to determine under what circumstances Head Start achieves its greatest impacts and for which children (US Department of Health and Human Services, 2010).…

This study explores young children's images of science and scientists, their sources for scientific knowledge, and the nature of their science-related experiences. A cross-sectional design was used to study how students' ideas differ over the first three years of elementary school. A modified version of the Draw-a-Scientist Test (DAST) and a…

Objective: Basal ganglia abnormalities have been suggested as contributing to motor, social, and communicative impairments in autism spectrum disorder (ASD). Volumetric analyses offer limited ability to detect localized differences in basal ganglia structure. Our objective was to investigate basal ganglia shape abnormalities and their association…
