What cognitive processes influence how well we maintain information in visual short-term memory (VSTM)? We used a developmentally informed design to delve into the interplay of top-down spatial biases with the nature of the internal memory codes, motivated by documented changes for both factors over childhood. Seven-year-olds, 11-year-olds, and…

The integration of engineering concepts and practices into elementary science education has become an emerging concern for science educators and practitioners, alike. Moreover, how children, specifically preadolescents (grades 1-5), engage in engineering design-based learning activities may help science educators and researchers learn more about…

Purpose: This study set out to examine the relationship between step frequency and velocity to develop a step frequency-based equation to predict Chinese youth's energy expenditure (EE) during walking and running. Method: A total of 173 boys and girls aged 11 to 18 years old participated in this study. The participants walked and ran on a…

The present study examined the concurrent and prospective, longitudinal effects of childhood negative emotionality and self-regulation on allostatic load (AL), a physiological indicator of chronic stress. We hypothesized that negative emotionality in combination with poor self-regulation would predict elevated AL. Mothers reported on children's…

Background: In general, children with specific language impairment (SLI) tend to fall behind their typically developing (TD) peers in educational attainment. Less is known about how children with SLI fare in particular areas of the curriculum and what predicts their levels of performance. Aims: To compare the distributions of performance of…

The article discusses how the use of ethnographic approaches to the study of researcher-child relations highlights the importance of structures that shape and define children's actions. The discussion is illustrated by using case study material from research with pre-school and pre-adolescent children in Indian educational settings. The article…

Environmental education programs aiming to enhance children's environmental attitudes in a pro-environmental direction require background information, such as age and sex differences, to ensure appropriate design. We used the 2-MEV model with its domains "preservation" and "utilization" of nature to assess a four-day program at…

This study examined punishment of excluders and compensation of victims after observing an instance of social exclusion at various phases of adolescent development. Participants (n = 183; age 9 to 22 years) were first included in a virtual ball-tossing game, Cyberball, and then "observed" the exclusion of a peer. Subsequently, they…

Research suggests that online communication is associated with increased closeness to friends and friendship quality. Children under 13 years of age are increasingly using social networking sites (SNSs), but research with this younger age group is scarce. This study examined the relationship between SNS use and feelings of belonging among children…

The aim of this cross-sectional study was to describe the social skills that crucially affect children's social behaviour in the school. Our objective was to gather information about the functioning of social skills from middle childhood to early adolescence. The sample consisted of 7-, 9-, and 11-year-old Hungarian students (N = 1398). Based on…

Information and communication technology (ICT) and Web 2.0 have the potential to impact on learning by supporting inquiry, literacies, collaboration and publication. Restrictions on the use of these tools within schools, primarily due to concerns about discipline and child safety, make it difficult to make full use of this potential in formal…

Handshape works differently in nouns versus a class of verbs in American Sign Language (ASL) and thus can serve as a cue to distinguish between these two word classes. Handshapes representing characteristics of the object itself ("object" handshapes) and handshapes representing how the object is handled ("handling" handshapes)…

To examine age trends in precedent-setting decisions and the effects of these decisions on perceptions of authorities, preadolescents and adolescents were presented with deontic rule infractions that occurred in the absence or presence of mitigating circumstances. In Study 1, in the absence of mitigating circumstances, adolescents recommended…

The role of cognitive vulnerability in the development of depressive symptoms in youth might depend on age and gender. The current study examined cognitive vulnerability models in relationship to depressive symptoms from a developmental perspective. For that purpose, 805 youth (aged 10-18, 59.9% female) completed self-report measures.…

The purpose of this paper is to provide findings from a study into a school peer mentoring program which matched children aged between 9 and 12?years of age who were bullied or at-risk of being bullied with older student mentors. In total, 372 mentees as well as a comparison group of 1,249 young people from 22 English schools completed a…
