Advocates artificial neural networks as models for cognition and development. Provides an example of how such models work in the context of a well-known Piagetian developmental task and school science activity: balance beam problems. (Contains 59 references.) (Author/WRM)

Two experiments examined developmental changes in reasoning about intensive quantities--predicting mixture intensity of pairs of liquids with different intensities of red color. Results showed that cognitive averaging in this domain developed late and slowly. Predominating up to 12 years was an extensivity bias, a strong tendency to use rules that…

Adult musician's brains show structural enlargements, but it is not known whether these are inborn or a consequence of long-term training. In addition, music training in childhood has been shown to have positive effects on visual-spatial and verbal outcomes. However, it is not known whether pre-existing advantages in these skills are found in…

Based on qualitative research conducted from 1998 to 2001, this article describes classroom interactions in a high school and examines two uses of rules: one associated with confinement, and another associated with cognitive skills development. Though the two forms overlapped, the first was more prevalent in self-contained classes, and the second…

The articles in this collection consider one very interesting puzzle of development: U-shaped developmental functions. At some point during development, an organism might exhibit what seems like a regression from its expected developmental trajectory and, according to continuity models of development, this is aberrant. In this special issue,…

This study reconsiders a series of drawing tasks (Goodnow, 1978) in which children have to modify their stereotypical drawing of the human figure to represent a person in movement. Another task, in which children have to differentiate the drawing of a kangaroo from that of a person, is also considered. According to a neo-Piagetian model of drawing…

Two experiments tested predictions from a theory in which processing load depends on relational complexity (RC), the number of variables related in a single decision. Tasks from six domains (transitivity, hierarchical classification, class inclusion, cardinality, relative-clause sentence comprehension, and hypothesis testing) were administered to…

This article provides an empirical evaluation of an indexing technology, topic maps (ISO 13250), in the context of an academic task in a higher education context. Topic maps are a form of indexing that define and display the interrelationships between various topics in a given domain, as well as anchor these topics to specific resources that help…

One of the most challenging daily experiences of teaching young adolescents is helping them transition from Piaget's concrete to the formal operational stage of cognitive development during the middle school years. Students who have reached formal operations can design and test hypotheses, engage in deductive reasoning, use flexible thinking,…

There is considerable interest in the role of mental state language in theory of mind development. This study examines cognitive and desire state discourse of 43 mothers during play interactions with their two-year-old children and theory of mind as indicated by a battery of false belief tasks around the age of five. Desire state comments of…

The number of children and adolescents accessing the Internet as well as the amount of time online are steadily increasing. The most common online activities include playing video games, accessing web sites, and communicating via chat rooms, email, and instant messaging. A theoretical framework for understanding the effects of Internet use on…

As children develop, they process information more rapidly. The primary aim of this study was to determine whether processing speed in the language domain develops at the same rate as global processing speed. A second aim was to determine the stability of processing speed throughout childhood and adolescence. Children (N = 116) were tested on 10…

The study of neurobehavioral development focuses on the mechanisms through which the experiences of an individual influence the ontogeny of brain circuits that ultimately control complex functions, such as social engagement, mood and emotional regulation and cognition. Advances in experimental approaches and technologies provide opportunities to…

In this paper a relationship is established between writing and early literacy in young children. The age at which early literacy begins to develop in young children varies with each child. For many children, literacy begins to appear in activities such as pretend play, drawing, conversations about storybook plots, and conversations about words or…

This handbook, written for teachers, art teachers, and parents of young children, describes actual elementary school classroom experiences. Each anecdote is juxtaposed with a simple explanation of its philosophical and psychological rationale. Symbolic representation of the environment through art making is seen as a natural language, a…
