Attempts to replicate Inhelder-Piaget results showing that a formal operational thinker uses all 16 binary operations of truth-functional logic. Results of present study suggest that the quality and complexity of usage of operations (as opposed to quantity) increases with age. (DP)

A presentation of arguments demonstrating piaget's sensorimotor stages in Hebb's terms, and the suggestion for performing a computer test. This paper is an early progress report of an attempt to translate some plausible arguments into a rigorous demonstration. (Author)

This study is aimed at trying to discover the isolable characteristics of intelligence, of the kind of mental processes which result from it, and of the relationship between intelligence and the formation of concepts. (Author)

The research on cognitive style suggests that there is tremendous variability in the way in which individuals process information and hence in the manner in which they approach individualized instructional programs. (Author)

The study was conducted to determine if the cognitive environment of the child from a high ability family could be classified as expansive or restrictive. It was concluded that mothers of gifted children have both styles available to them. The individual orientation of the high ability mother dictates the s tructure utilized. (CD)

Summarizes Piagetian developmental psychology, and describes a study in which trainee elementary school teachers administered Piagetian tasks to pupils. During this time the teachers were being instructed in the development of children's thought processes. Results support the continued use of the method. (AL)

A large proportion of the UK adult population has very poor literacy and/or numeracy skills (see the 1999 Moser Report, the 2003 "Skills for Life" Survey and the 2006 Leitch report). In 1999, the Moser report found that approximately 20% of adults in England had severe literacy difficulties, whilst around 40% had some numeracy problems.…

This study investigated several levels of internal and external disequilibrium and their interaction. Subjects were 63 fifth graders assigned to three groups according to their degree of internal disequilibrium. Internal disequilibrium was measured by the amount "level mixture" (a tendency to respond to various events at several…

This account of a new approach to social studies curriculum takes the form of an introductory statement on the model curriculum which is being developed in the Contra Costa County Schools of California. Three levels of knowledge are distinguished: (1) concepts, (2) significant ideas, (3) specific facts, with the students progressing from 3 to 1.…

The OST is a technique quite different from anything reported elsewhere in the literature. The model underlying OST work assumes that an individual's intellect, at any given point in time, is the set of all information he has at his disposal at that point in time. The set of concepts an individual has at any point in time may radically change over…

Metalinguistic knowledge and its antecedents were studied in an investigation of performance- and reflective-based knowledge in 27 young children. Piagetian assessment tasks were used to determine cognitive functioning level, and then the children were tested as to knowledge of words' structural and significative features. Results support an…

Argues that the adoption of the bureaucratic structure, with its concomitant values, has proven to be incompatible with both intellectual and human development, that a learning environment that promotes simultaneously both intellectual development and humanism must be created, and new forms of organizational structure to achieve goals currently…

The results of this study provide evidence that schools reduce the variance of learned cognitive skills among children. (MM)

A critical evaluation of the use of stochastic independence in psychological research is provided, considering (1) confirming the null hypothesis; (2) power of the statistical test; (3) Simpson's paradox; and (4) between-subjects and within-subject correlations. The importance of formal models in studying (in)dependence is emphasized. (SLD)
