An experiment was conducted to test the hypothesis (derived from Piaget's theory of cognitive development) that the structure of children's drawings and play-constructions, being expressions of the same underlying function, should be similar. Two groups of 4- and 6-year-old nursery school children were given a testing task consisting of an orally…

Learning to program involves developing an understanding of two hierarchies of concepts. One hierarchy consists of data and extends from very literal data (which represents only itself) to very abstract data incorporating variable values in complex interrelationships. The other hierarchy consists of the operations performed on the data and extends…

The two studies reported here explore recent findings indicating that few relationships exist between environmental stimulation and cognitive development during the first 6 months of life. In the first study, three separate home visits (two 90 minutes and one 30 minutes long) were used to assess the physical and social environments of 100…

Data obtained under naturalistic conditions do not support the notion of a close fit between the growth of geometric concepts during the concrete operational period and "realism" in art. Realism here refers to the ability to portray the objective proportions of a figure, to coordinate spatial relations and distances, and to represent a…

A theory of adult cognitive development which includes two post-formal operational stages is described. The paper is divided into three sections. The first section provides background for discussion of the theory. A case study in which various employees in a hypothetical organization react to a problem is provided. Examples of pre-logical,…

Twelve learning disabled (9-12 years old) boys were identified according to special class placement, WISC-R (Wechsler Intelligence Scale for Children-Revised) and performance measures. A group demonstrating a verbal WISC-R deficit was sex- and age-matched with a normal group. Electroencephalograms (EEGs) were collected while these individuals…

The terms and concepts children used to explain their beliefs about computers before and after classroom exposure to microcomputers were studied to identify misconceptions about computers that could interfere with computer-based learning. Children in each of two classrooms at the Bank Street School for Children were interviewed individually on…

The paper reviews research from 1970 to the present in the study of cognitive processing and language in deaf students and adults. Studies address the following topics: differential specialization (direct observation of clinical populations and indirect methods examining handedness, dichotic listening, and visual hemifield differences); cerebral…

Based on a set of theoretical assumptions relating to the cognitive modificability of low functioning adolescents, a program of Instrumental Enrichment was developed and implemented with 41 hearing impaired secondary students. The primary goals of Instrumental Enrichment included: (1) improving performance in spatial relations, (2) improving…

Attempts to specify whether previously reported limitations on young children's full-report capacity lay in a smaller amount of available information, in a shorter trace duration of information in visual information storage (VIS), or in poorer coding of information into permanent storage.

Presents a day care curriculum for infants and toddlers which is designed to provide maximum learning experiences and is based on Piaget's and Erickson's theories of infant development. (Author/ED)

A study suggesting semantic rather than syntactic early language acquisition by children. (CH)

The purpose of this article is to outline some of the characteristics of children's notions of physical causality and to relate this to how one might expect the typical five-year-old, eight-year-old, and twelve-year-old to approach a problem in science. (Author)

Author concerned himself with the generalizability of Jencks' conclusions to educational policy problems in developing areas. (Author/RK)
