Cites research findings to refute Piaget's contention of stages of cognitive development. Advocates continuous cognitive differentiation as a model. (CP)

One group of elementary education majors received an algebraic instructional treatment of a unit on linear absolute value equations while another received a geometric treatment. The hypothesis of an aptitude-by-treatment interaction was statistically confirmed. (MN)

A 16-item conditional reasoning test was given to 281 students in grades 8, 10, 12, and 14. Developmental patterns of performance were examined. (Author/JMB)

Describes a program being conducted within the chemistry department of Xavier University, New Orleans, Louisiana, to improve the abstract reasoning abilities of freshmen science majors. The project is based upon the philosophy developed by Jean Piaget. (SL)

Three experiments investigated whether abstract as well as concrete sentences can be processed in a holistic manner. Results suggest that the processing of both types of sentences involves construction of particularized, holistic mental representations that contain information and inferences based on context and knowledge of language and the…

Kohlberg's theory of moral development is restated in less technical terms, with emphasis on the concepts of: (1) moral judgment, rather than behavior, values, or feelings; (2) "stages," describing consistencies in moral reasoning procedures; and (3) "better" stages, measuring structurally more adequate levels. (MJB)

While it is clear that schizophrenic patients often exhibit disordered thinking, the specific nature of the deficit and its role, either as a basis of abnormal behavior or as a symptom of malfunction in some underlying control process, remain to be clarified by research and by theory. Describes two experiments on the performance of conceptual…

Reports three experiments with kindergartners and first graders which used one-trial multidimensional reasoning tasks like those of Toppino (Journal of Experimental Child Psychology, v30, p496-512, 1980). Feedback information and preliminary experience with simple forms of the task produced high performance levels, and verbal labeling in the…

Without opportunities to acquire multiple forms of literacy, children will be handicapped in their ability to participate in the legacies of their culture. The forms in which thinking occurs should not be subjected to the status differences and inequities of society. (MLW)

Analyzes the effect of language of instruction on the verbal reasoning of sixth grade French-English bilinguals (N=36). Results showed a significant interaction between language of instruction and language of presentation and differences associated with level of difficulty and mean response times. (Author/CB)

Verbal analogical reasoning tasks are described as potentially valuable in the assessment and management of subtle linguistic defects less easily detected by standardized language tests. Semantic and structural factors that should be considered in the development of verbal analogies as test items are cited, as well as adaptations for nonreaders.…

Maintains that imaginative philosophical dialogue is an essential and necessary condition to education. Contends that the development of an autonomous person who has the ability to think well and to think for him or herself about matters of importance is essential in a democracy. (Author/JDH)

Investigates the relationship between class inclusion and reasoning in 56 Dutch Children between 6 and 14 years of age. Concludes that when the children failed to respond correctly to questions about the validity of syllogisms, they did so because they lacked sufficient understanding of the premises. (HOD)

Three experiments using college students examine the processes involved in deductive reasoning. Effects of training in classroom and laboratory situations confirmed the authors' hypothesis that people use pragmatic reasoning schemas rather than syntactics rules of logic for problem solving. Training materials used in experiments 1 and 3 are…

Experiments to probe the nature of one mode of thinking, imagined spatial operations, have been devised. Results confirm that the mind can model physical processes, subjecting them to the geometric constraints that hold in the external world. The experimental work and implications are discussed in detail. (MNS)
