Explores the role of premature cognitive closure in the development of inferential reasoning among 62 children aged 7, 9, and 12 years through two studies. Results indicate that despite a strong tendency to close on single alternatives, most children correctly assigned nonzero probabilities to each of the possible alternatives. (RJC)

The performance of 10 language-learning disabled ninth graders was compared to that of 16 normally achieving ninth graders and 10 normally achieving fourth graders on a modified Piagetian problem solving task sensitive to cognitive changes in early adolescence. Results suggested significant conceptual limitations in the language-learning disabled…

Comparison of 2 totally blind, 2 visually impaired, and 9 normally sighted children (ages 5-8) on tasks of visual perspective taking found that the totally blind children were older than the other children when they mastered the tasks, made the highest percentage of errors before mastery, and made different errors.

Three studies examined preschoolers' use of desires to solve theory of mind problems. Findings indicated that even young children could correctly attribute a false belief to an agent when that belief was about the status of a pretense. Subjects found it easier to attribute a false belief when the desires of the agent were eliminated. (Author/KB)

Investigates the influence of socio-affective context on the interactive modalities surrounding problem-solving discussions conducted with 8-year-old children. Results suggests that reciprocal friendship facilitates collaboration and the organization of collective work. Discusses two rival hypotheses of socio-affective proximity and…

Effective teaching should focus on representational change, which is fundamental to learning and education, rather than conceptual change, which involves transformation of theories in science rather than the gradual building of knowledge that occurs in students. This article addresses the question about how to develop more efficient strategies for…

This report describes a study which examined the ways in which children interact and make sense of a range of mathematics problems by working in pairs. Studies of collaborative peer dyads' problem solving have generally been influenced by Piagetian or Vygotskian theories and research approaches. It is noted that the process of dyad collaboration…

It has been shown previously that many students solve chemistry problems using only algorithmic strategies and do not understand the chemical concepts on which the problems are based. It is plausible to suggest that if the information is presented in differing formats the cognitive demand of a problem changes. The main objective of this study…

Recurring pressures for fiscal restraint threaten the existence of educational programs, such as competitive debate, which are not publicly perceived to produce worthwhile outcomes. Since debate is misunderstood and expensive, its advocates must be prepared to provide solid evidence of its benefits. Unfortunately, methodological weaknesses in…

This report proposes a modification of Jean Piaget's concept of "creative abstraction," the mechanism of creative thought, which develops both intelligence and creative ideas. By reflecting on one's actions and the coordinations of actions, the individual constructs new relationships, links, rules, or correspondences between and among them.…

This paper examines the category-theoretic formulation of cognitive development introduced by Piaget in the late 1960's and elaborated during the 1970's. The new theory is interpreted as the focal point of Piaget's investigations into topics such as function, correspondences, and commutability. Hypotheses arising from Piaget's new model were…

Research using expectancy models has shown contraceptive choice among adults to be a rational process in that intentions and behaviors reflect an individual's beliefs, values, attitudes, and perceptions of social norms. This study examined whether such an approach could accurately represent adolescents' contraceptive decision-making. It used the…

A theory of adult cognitive development which includes two post-formal operational stages is described. The paper is divided into three sections. The first section provides background for discussion of the theory. A case study in which various employees in a hypothetical organization react to a problem is provided. Examples of pre-logical,…

Based on a set of theoretical assumptions relating to the cognitive modificability of low functioning adolescents, a program of Instrumental Enrichment was developed and implemented with 41 hearing impaired secondary students. The primary goals of Instrumental Enrichment included: (1) improving performance in spatial relations, (2) improving…

The formal operations skills and problem solving performance of 60 gifted girls (grades 4 through 6) were investigated. Ss were given Piagetian tasks which involved conservation of mass and weight, use of proportion, oscillation of the pendulum, and projection of shadows. Among findings were the following: (1) no relationship between IQ and either…
