This article used two studies to investigate sign and symbol mediation in children aged 8-11 years. In role play, children exist at one at the same time in objective reality and their representation of reality. We cannot observe their mental representation directly, but the issue of whether signs or symbols mediate early role play is an important…

The present research examines the ability of children as young as 4 years to use models in tasks that require scaling of distance along a single dimension. In Experiment 1, we found that tasks involving models are similar in difficulty to those involving maps that we studied earlier (Huttenlocher, J., Newcombe, N., & Vasilyeva, M. (1999). Spatial…

Explores the role of symbolic play in the cognitive and psychic development of the normal child and describes the autistic child. Reviews a model treatment program for autism developed at the City College of New York, discussing the therapeutic role of symbolic play in that model. (Author/MJL)

Reported are research findings that (1) illustrate the importance of primary spatial orientation for children's and adults' use of symbolic spatial skills and (2) indicate the importance of the distinction between primary and secondary spatial orientation. At least two major ways exist in which humans gather and use spatial information. The…

The development status of the communicatory behavior of 11 autistic children (4 to 9 years old) was assessed during free play sessions under two conditions: when teachers were present to direct the children's behavior and when teachers were absent and the children played among themselves. (Author)

Reports research which reveals the difficulty children have in understanding (1) the real purpose of written language and (2) the abstract, technical vocabulary of language study and reading. (SW)

Children's developing competence with symbolic representations was assessed in 3 studies. Study 1 examined the hypothesis that the production of imaginary symbolic objects in pantomime requires the simultaneous coordination of the dual representations of a dynamic action and a symbolic object. We explored this coordination of symbolic…

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…

Visual and auditory stimuli were presented to children to measure symbol processing abilities. Slides which required matching the similarities in two objects in a group of three were presented. At times the matching criteria varied between function, color, and form. Reaction time was quicker when matching by color than by function, which was…

More than 300 citations of books, articles, and conference papers published primarily within the last 20 years are listed with brief descriptions. The works include discussions of developmental theory, art education, art criticism, aesthetics, and philosophy of science as well as experimental studies. Research topics cover aspects of cognition…
