Two non-verbal cognitive systems, an approximate number system (ANS) for extracting the numerosity of a set and a parallel individuation (PI) system for distinguishing between individual items, are hypothesized to be foundational to symbolic number and mathematics abilities. However, the exact role of each remains unclear and highly debated. Here…

This research investigated whether symbolic understanding of pictures in low-functioning children with autism is mediated by iconicity and language. In Experiment 1, participants were taught novel words paired with unfamiliar pictures that varied in iconicity (black-and-white line drawings, greyscale photographs, colour line drawings, colour…

Finds that (1) playfulness is a trait related to divergent, creative thinking; (2) allowing young children to play with objects can lead to increased performance on problem solving and divergent thinking tasks involving the same or similar objects; and (3) play training leads to short term gains in young children's cognitive performance.…

Discusses the use of visual media as symbol systems that gather, package, and convey knowledge. Media's different and often unique symbol systems are looked at as potentially serving as cultivators of mental abilities. Forty-nine references are provided. (Author/CHC)

Developmental research suggests that some of the mechanisms that underlie numerical cognition are present and functional in human infancy. To investigate these mechanisms and their developmental course, psychologists have turned to behavioral and electrophysiological methods using briefly presented displays. These methods, however, depend on the…

The structure of cognitive abilities was examined through tests administered to 81 prelingually deaf Yougoslavian children (ages seven to eight). Results suggested the existence of two levels of cognitive organization: (1) automatic (involving highly integrated perceptual skills and short-term memory); and (2) representational (involving symbols…

Explores the relations among combinatorial capacities in language, symbolic play, blockbuilding, and nonsemantic action sequences within a sample of 18- to 24-month-old children, as well as assessing the developmental level of a selected subset of concepts. (HOD)

Factor analytic studies suggest that there are six replicable second order cognitive factors. These six factors lend themselves to being interpreted as aspects of Royce's three ways of knowing: conceptual, perceptual, or symbolical. This view provides a unified explanation of the second and third order factors. (Author/CTM)

Proposes that cognitive developmental stages can be accounted for in terms of information processing factors which limit the highest level of cognitive system which children can attain at any given age. Delineates four progressively more complex levels of cognitive mediation of the environment. Two experiments which support the developmental model…

The effects of different models of exploration questioning on young children's associative fluency were examined in two experiments with kindergarteners. It is concluded that asking descriptive and difference exploration questions are most facilitative of children's associative fluency. (Author/SEW)
