The current experiment investigated the effect of differential training histories on responses to a 5-term linear chain of nonsense syllables (described here with sequential, alphabetical characters; A [is less than] B [is less than] C [is less than] D [is less than] E) across unreinforced probe trials. Participants' responses to nonarbitrary…

Individuals can infer what others are likely to know by clustering knowledge according to common goals, common topics, or common underlying principles. Although young children are sensitive to underlying principles, that manner of clustering might not prevail when other viable means are presented. Two studies examined how a sample of 256 children…

A label can convey nonobvious information about category membership. Three studies show that preschoolers (N144) sometimes ignore or reject labels that conflict with appearance, particularly when they are uncertain that the speaker meant to use those labels. In Study 1, 4-year-olds were more reluctant than 3-year-olds to accept that, for example,…

The aim of this study was to develop a model of students' energy concept development. Applying Case's (1985, 1992) structural theory of cognitive development, we hypothesized that students' concept of energy undergoes a series of transitions, corresponding to systematic increases in working memory capacity. The US national sample from the Third…

The impact of cognitive development on enhancing the motor activities and sporting performance of the individual is discussed.

This study examined the knowledge and strategies that young children used for comparing sizes of geometric figures. Sixty-nine children from the ages 3 to 6 years were asked to compare sizes of geometric figures and their placement and adjustment strategies were observed. The children were also presented with strategies for comparing sizes and…

This experimental study explores how 60 primary-age children's (9-11 years old) understanding of rocks was effected by instruction that used the conceptual structure of the rock cycle together with the analogy of aluminium can recycling. Using a combination of probes into children's understanding, including concept maps and semi-structured…

It is commonly assumed that artifacts are named solely on the basis of properties they currently possess; in particular, their appearance and function. The experiments presented here explore the alternative proposal that the history of an artifact plays some role in how it is named. In three experiments, children between the ages of 4 and 9 years…

Four experiments with the habituation procedure investigated 14-22-month-olds' ability to attend to correlations between static and dynamic features embedded in a category context. In Experiment 1, infants were habituated to four objects that exhibited invariant relations between moving features and motion trajectory. Results revealed that…

This study provides a glimpse into understanding the potential benefits as well as harm of playing video games from the perspective of six Malaysian secondary school students, aged 16-17 years old. The rationale of the study is to enable parents, educators, administrators and policy makers to develop a sound understanding on the impact of playing…

Since boys are more commonly diagnosed with Attention Deficit Hyperactivity Disorder (ADHD) than girls, the majority of theories and published research studies of ADHD have been based on samples comprised primarily (or exclusively) of boys. While psychosocial impairment in girls with ADHD is well established, the neuropsychological and…

The aim of this article is to examine the legal possibilities available to creators of children's games, enhancing art education. It focuses on the type of games that enrich the learning experience by means of works of visual, verbal or musical art. I do not deal with the technology of the digital age, but examine the educational art game as a…

Recognising and nurturing giftedness in young children presents an important challenge to educators. This study sets out to identify and support gifted children through the provision of a rich learning environment in the Nursery (Kindergarten) setting. Practitioners in the Nursery aimed to provide cognitively challenging activities appropriate to…

This article reviews research conducted on social comparison processes in the classroom since Festinger proposed his theory of social comparison. It covers the theoretical framework of social comparison theory, and it is organized around the following themes: motives for social comparison, dimensions of social comparison, direction of social…

This article examines the mechanisms linking health to the educational attainment of adolescents. In particular, it investigates the role of cognitive/academic achievement and a variety of psychosocial adjustment factors in explaining this relationship. Using data from the National Longitudinal Survey of Youth 1997 cohort (NLSY97), we estimate…
