We investigated a test of strategic reasoning (the Windows task) that in different studies has yielded contrasting pictures of young children's executive abilities [Russell, J., Mauthner, N., Sharpe, S., & Tidswell, T. (1991). "The 'windows task' as a measure of strategic deception in preschoolers and autistic subjects." "British Journal of…

Piaget's theory of developmental stages was implemented in an elementary school curriculum. Some successful learning experiences are described. (CP)

A proposed study of the differences in the way children perceive, approach, and behave in problem-solving situations is described. The behavioral measure to be used is "glancing," which has been related to outerdirectedness. Children will be given two sets of two puzzles to put together. On the basis of the number of glances and the situation in…

Argues that Susan Sugarman's article in this issue contains some valid criticism of assumptions in developmental psychology, but that some of her conclusions regarding other assumptions need to be questioned. Suggests that many problems raised by Sugarman would disappear if developmental psychologists concentrated on children's early achievements…

Investigates the development and production of spatial deictic terms ("this/that", "here/there", "my/your") in the context of a hide-and-seek game using preschool children and college age adults. (Author/ED)

Argues that there are significant ways in which neither Piaget nor his successors in developmental psychology have adequately described the child's mind and how it changes. Proposes alternative guidelines for research that aims more directly at identifying essential constituent features of the child's mental reality. (PCB)

Although a psychological theory of stages of transformation in human development currently exists, organizational researchers have yet to elaborate and test any theory of organizational transformation of comparable elegance. According to the organizational stage theory being developed since 1974 by William Torbert, bureaucratic organization, which…

This paper is a critical examination of Piaget's formulations on cognitive development based on recent social learning research. It is suggested that learning to conserve does not seem immutably dependent on the child's attaining some maturational age-related cognitive stage and that Piaget's theorizations do not sufficiently consider social…

The project is based on a general systems approach. Developmental stage theory is employed as a starting point, and the developmental "minitasks" which act as stair risers from one developmental level to another are carried through with the use of Bloom's cognitive taxonomy. (Author/DLS)

An analysis of the quantitative processes underlying conservation of quantity is presented. Models of three quantitative operators--subitizing, counting, and estimation--are derived from adult performance in quantification tasks, and some features of the operators are described. The emergence of conservation is described in terms of the…

Discusses difficulties of examining Jean Piaget's work, caused in part by his own revisions and earlier, inadequate interpretation in English translation. Examines common misunderstandings of Piagetian developmental stages and similar misinterpretations of his ideas on education. Focuses on importance of other disciplines, including psychology and…

Reports a series of studies conducted to investigate possible differences in the exploratory manipulation and play behavior of human infants 7-1/2- 11-1/2 months of age as a function of the attributes of the stimulus, the familiarity of the subject with the stimuli, the age and sex of the infants, and individual differences. (Author/CS)

TO IMPROVE THE DEVELOPMENTAL RATE OF CULTURALLY DEPRIVED CHILDREN, A PRESCHOOL PROGRAM WAS OFFERED WHICH CONSISTED OF A PLANNED SEQUENCE OF ENVIRONMENTAL STIMULATION BASED ON THE THEORY THAT COGNITIVE DEVELOPMENT PROCEEDS THROUGH MOTOR-PERCEPTUAL-SYMBOLIC PHASES. SEVENTY-TWO DISADVANTAGED CHILDREN WERE DIVIDED INTO THREE MATCHED GROUPS. GROUP A…

Based on the papers presented at the 1996 Symposium of the Jean Piaget Society and highlighting the extent to which Piaget's ideas have served to scaffold contemporary thinking about every aspect of conceptual development, this volume examines the nature of conceptual development, its foundations, and the sources of its novelties. The chapters…

An analysis of children's narrative composition and art revealed concurrent development at both a general structural level and at a fine-grained detail level. A three-part study investigated whether this general cognitive pattern would be maintained across a different range of tasks: literary composition, scientific reasoning, and working memory.…
