Systematic observations of thousands of high school students in the California Mentally Gifted Minors/Gifted and Talented Education programs identified five principles underlying the development of high level thinking skills in this population: (1) Exceptional performance on any criterion requires mutually reinforcing antecedents, the effects of…

Responding to recent advances in developmental and cognitive science research on knowledge acquisition, this report presents a theoretical framework for analyzing cognitive development as a process of learning. The first section summarizes three developmental characteristics recognized in both the Piagetian and the quantita experimental tradition:…

Baumeister's (1968) hypothesis that mentally retarded children exhibit depressed levels of performance and greater intra-individual variability when compared to intellectually non-handicapped children of similar chronological age was investigated. Eight 10-year-old educable mentally retarded boys and 16 non-handicapped boys, matched by either…

To investigate young children's understanding of metaphorical language, 90 chidren from preschool to third grade were read stories ending with metaphorical sentences of varying degrees of difficulty--sentences representing more or less predictable story outcomes and differing in the complexity and explicitness of their figures of speech. After…

This study attempted to explain the findings of classical studies about young children's classification ability, namely that young children: (1) categorize on the basis of perceptual or concrete properties, (2) classify in a linear, nonhierarchical manner, and (3) use inconsistent criteria for classification. The study further proposed that…

This paper focuses on the ways in which nonparental significant adults affect adolescents' lives. Section 1 provides an overview of the literature regarding nonparental adults and their impact on adolescents. The concentration is on role models and significant adults. Section 2 explores the shift in developmental theory to an interactionist…

While research provides many examples of preschoolers' overconfidence and overestimation of performance, there has thus far been relatively little investigation of the source of these qualities. Recent research suggests that even 2- and 3-year-old children possess a "theory of mind," and know that they and other people think, know,…

Two studies investigated the origins of message evaluation skills in preschool children. In the first study, 14 preschoolers and 14 second graders were asked to evaluate the informativeness of pictorial messages in a referential communication task in two sessions. Results showed that the younger children overestimated the informativeness of…

This handbook provides a collection of stimulation activities that encourage a child's physical and mental growth from birth to five years of age. Emphasis is placed on making stimulation aids that are inexpensive or can be made from scrap materials. Advice is given about ways to carry out designated activities. All activities have been tried and…

The purpose of this study was to determine the types of research methods used to study cognitive processing development in gifted learners, from 1975-1986. Of 870 research publications identified on giftedness, 522 publications (60 percent) dealt with cognitive processing development. Research designs used most frequently were causal-comparative,…

In England, a 40-item test of a child's ability to draw the ground floor layout of his or her home was developed. Findings of initial analyses indicated that subjects' drawings improved between the ages of 6 and 12 years. In order to test the cross-cultural validity of the standardization of the test and to see if the order of concept development…

Many science educators are concerned with students' ability to understand science as a process and with their conceptions of scientific knowledge. Preliminary work has shown that the use of a model organizer can result in student perceptions of improved understanding, but the reason for this effect is not known. This research was undertaken to…

This study analyses the problems facing classroom teachers who must cope with young children who have experienced the death of a parent, a sibling, or a close grandparent. A questionnaire was designed to secure information on the impact of the death of a loved one on the cognitive development of young children. Teachers were asked about the extent…

Transitional situations, such as those experienced by work study students, may create cognitive difficulties by requiring people to simultaneously use both a learning and a use logic. To examine this phenomenon, a problem solving task (electrical schemata of a washing machine) was administered to 43 full time students and 51 work study students…

The theoretical foundations of thinking skills models differ. One category of thinking skills programs uses the cognitive process approach on the premise that thinking abilities depend upon certain fundamental processes. Thinking skills programs that present a strategic approach to thinking are called heuristics-oriented programs, and focus on an…
