The article describes research which attempted to discover whether emotionally disturbed children functioned at Piagetian levels of abstract thought similar to normal children. (CD)

Twenty first-graders observed an adult model perform a quantity conservation task. The children were then tested on a series of generalization tasks immediately, after one week, and after three months. The results suggested that the social experience of observation appeared to activate a cognitive restructuring of the children's mental operations.…

Explores the hypothesis that there is a decline in operational thought ability in the elderly. Two samples of elderly males, with mean ages of 71.80 and 74.29 years respectively, were tested for their ability to conserve mass, surface areas and volume. (BD)

Discusses the theories of Piaget, Bruner, Lifschitz and Langford, Vygotsky and others. (SB)

Discusses the use and stimulation of lateral, or divergent, thinking to promote creativity. (SL)

Proposes that phonological development involves the three fundamental processes of perception, organization and production. Acquisition proceeds by the suppression of natural phonological processes in a systematic fashion. Processes slide through a child's system, appearing first as constraints on perception, and later on organization and…

A sample of 86 college students aged 18 to 35 years of age were asked to solve three formal operations tasks and to participate in a problem-finding task. No relation was found between performance on problem-finding and the formal operations task. (JMB)

The article discusses a framework of reading disability based on comprehensive theories of cognition and reading. Reading problems are considered in terms of the Information Integration theory of cognition. Goals for developing remedial instruction based on the theory are also discussed. (Author/DB)

Explores the development of children's ability to plan their drawings. Presents a conceptual framework and a process-structural model of the planning of drawings in childhood. Two experiments support the model's prediction of different patterns of results as a function of the working memory capacity of the subjects. (SKC)

The optimal way of imparting abilities to reason and to make decisions under uncertainty in undergraduate medical education is discussed in view of existing cognitive development theories of adults. Implications of these theories and published observations on the ways of thinking of undergraduate medical students are considered. Presented are…

Memory-based searching was compared in 15 developmentally delayed and 24 normal two-year-olds. In a relatively easy memory task, individual differences were minimal, but searching for a plausible alternative location based on memory revealed marked individual differences and an important difference in the cognitive functioning of the delayed…

Young, middle-age, and old adults ranked similarities of word pairs in a conditional rank-ordering task. Analyses of variance revealed an age-related decline in semantic processing but no such decline for elaboration. Older adults' retrieval was less compatible with initial processing than was the case for younger adults. (Author/ABB)

Tests the distinction between inferring new categories on the basis of property information (predicted to be difficult) and inferring new properties on the basis of category information (predicted to be easier) among 57 preschool children. (HOD)

The availability of several effective teaching models that allow the teaching of thinking skills and subject matter simultaneously proves that intellectual processes and content are not incompatible subjects for instruction. These models differ significantly from traditional models, and adequate training in them will require a thorough commitment…

Argues that knowledge from studies of individuals with sex chromosome abnormalities can further understanding of aspects of normal human development. Studies of XO girls, XXY boys, XXX girls, and males with a fragile X chromosome are summarized to demonstrate how results contribute to knowledge about normal cognitive development and about…
