The study examined 30 schizophrenic and 30 nonpsychotic but disturbed children (all residents at a psychiatric center and all between 8 and 17 years old) for cognitive deficits in logical thinking, symbolic imagery, and conservation within the Piagetian theory of cognitive development.

Two predictions based on H. Clark's and E. Clark's hypotheses of the acquisition of word meanings were tested: (1) when learning words which have both spatial and temporal meanings, children will understand the spatial meanings first, and (2) children understand the positive member of an antonym word pair before they understand the negative…

Describes a student's unique perspective on the algorithm for finding equations of non-vertical lines given one point and the slope. Indicates that students had a better understanding of what they were doing. (KHR)

Investigated the hypothesis that the meaning young children attribute to the word "big" may depend differentially on the object of reference. Children three and five years of age who were shown pairs of buildings and pairs of cars used a height rule for both classes of objects when interpreting big. (NH)

Examines the distinctions and interrelations between necessary and contingent knowledge and relates these concepts to the distinction between scientific and empirical validity. Considers how these distinctions can be applied to an understanding of morality, arguing for a relational rather than absolutist approach to questions of necessity. (JPB)

Maintains that there are core-specific and non-core-specific domains of knowledge, but that only the core-specific domains benefit from innate skeletal structures. Asserts that core skeletal domains are universally shared, even though their particular foci may vary. Emphasizes that individuals vary in terms of the noncore domains they acquire.…

Examined causal status effect (weighing cause features more than effect features in categorization). Presented adults and 7- to 9-year-olds animal descriptions wherein one feature caused two others. Asked which transfer item was more likely an example of novel animal. Found that both groups preferred an animal with a cause and an effect feature…

Finds that the construction of concept maps may help students make links between scientific concepts and related topic areas. Describes different methods of concept map analysis which illustrate different levels of conceptual development. (CCM)

The Piagetian concept of horizontality was studied in 195 fifth graders to determine the relationship between this concept and memory. (ST)

The aim of this study was to document the development of illness and health causality concepts in young hospitalized children (ages 4-10 years) whose stage of cognitive development may limit understanding of illness and treatment. It was hypothesized that distinct qualitative levels would characterize children's conceptions of illness and that…

Five arguments are presented as to the inappropriateness of Piaget's "stage of formal operations" as the final stage of cognitive development. (MJB)

This study examined the effects of judgment-contingent feedback and prior knowledge of 3 rules on the conservation learning of 188 kindergarten children. (Author/JMB)

Two thinking strategies, concept formation and dialectical reasoning, are discussed and illustrated. The need for schools of education to teach thinking skills is stated, and concepts which should be addressed are suggested. (Author/MT)

Responds to Biggs' article on the case presentation approach in clinical supervision, commending the author for drawing together two areas of psychology: case presentation in counselor supervision and cognitive development. Discusses three major contributions of, and three concerns with, Biggs' model. (NB)

Acquisition of sentient-nonsentient distinction in 48 children between four- and seven-years-of-age occurred later than animate-inanimate distinction. The children's use of naturalistic or nonnaturalistic explanations depended on the logical nature of events in which objects were involved rather than familiarity with objects themselves. Ability to…
