The present study was designed to explore the relationship between the theoretical models of cognitive development proposed by L. S. Vygotsky and J. Piaget. One hundred and four subjects aged four to sixteen years were selected. All subjects were in the average range of intelligence, were in the usual school grade for their age, and had no history…

Twenty-four papers prepared for a conference on Piagetian theory and its implications for the helping professions are included in this report. The conference included the following symposia: (a) Present Status of Formal Operations, (b) Implications of Piaget for the Development of Curriculum, (c) Arithmetic and the Development of Logical…

Research has indicated that across the second to fifth grade range, there was evidence to suggest a difference between the oldest and youngest groups in the memory representations which directed recall of logically related sentences. The developmental trend was from what seemed to be an unstable and fragmentary memory rperesentation, which…

Data from a Class Activities Questionnaire was used in the evaluation of the state gifted program in Illinois to determine patterns of cognitive and affective emphasis in gifted and average classes. Significant differences were found in the degree of emphasis on higher thought processes, classroom focus, and classroom climate. Significant…

This study was designed to: (1) investigate differential responding to stimuli that differ along a continuum of degree of discrepancy from a familiarized standard; and (2) attempt to determine if infants will show response decrement and recovery to conceptual categories. Fifty-five infants at two age levels (10 and 16 weeks) were familiarized with…

Explored the relationship between knowing how to think and teaching students to think. The findings indicated that development of pupil's intellectual capacities depend on an adequate assimilation of general methods of thinking and that psychology, logic, and pedagogy can today provide the teacher with the technical resources necessary to make…

Points out that an aspect of Piaget's theory, the concept of stage, is being misrepresented through vague and incorrect use of the idea. (Author/GA)

Data were collected on tactics used when making a sequence of set comparisons in terms of more or equal number. (MP)

The generally bleak achievement scores of deaf children are contrasted with the near normal reports of both IQ and conceptual development. (Author)

Seventy-five preservice elementary school teachers were given a Piagetian-related paper-and-pencil test involving the equilibrium of a beam balance. Results show a significant positive relationship between the developmental levels of the clearness, as measured by the test, and their performance on equation solving when different reversible…

Developmental changes in a variety of cognitive processes as a function of age and schooling were examined in 160 rural Guatemalan children aged 5, 7, 9 and 11 years. (BD)

Training in perspective-taking skills (the ability to imagine how objects look relative to one another from another person's point of view) resulted in considerable transfer of learning to other tasks and continued subject superiority over controls seven months later, indicating an inter-stage change in cognition. (MJB)

Findings indicate that advanced moral judgment and potentially radical political beliefs came together in mid-adolescence. (Author/AM)

Two sets of tasks designed to measure operational thinking and the problem-finding skill of asking general questions were administered to 7-, 9-, and 11-year-old children. Analyses performed on the quality of the children's questions revealed developmental trends consistent with earlier work on problem finding. (Author/JMB)

Examination of object word learning and use in beginning (vocabulary of less than 50 words) and advanced (vocabulary of more than 50 words) infant speakers indicated that both groups formed concepts, learned, and generalized words for the to-be-learned objects. Advanced speakers learned more words and concepts and engaged in broader generalization…
