Comparison of area and subtest scores on the Stanford Binet Intelligence Scale (Fourth Edition) for 15 autistic retarded children and 15 nonautistic retarded children found that the children with autism scored substantially lower in the verbal reasoning area and on the subtests of Comprehension and Absurdities than did the nonautistic children.…

We applied a mixed-method research design to investigate the patterns of reasoning used by novice undergraduate chemistry students to classify chemical substances as elements, compounds, or mixtures based on their particulate representations. We were interested in the identification of the representational features that students use to build a…

This paper examines past theories and conceptions of epistemology and the work of some key theorists currently working in the field, in the hope of motivating the development of an expanded conception and redescription of epistemology. The paper uses as a metaphor for the study six blind men who describe an elephant as like a rope, a tree, a fan,…

An initial description of the links between cognitive input, discourse rules, and the rules of sentence grammar is made, based on a technique developed for observing the translation of cognitive input into language in a spontaneous, practical speech event: descriptions of the lay-outs of apartments.

A multidimensional model of the growth of moral reasoning is described that is significantly different from those proposed by Kohlberg and Piaget. A study that tests several aspects of the model on university students is reported. The suggestion that well-developed chains of reasons are a prerequisite for the emergence of metaethical reasoning was…

This paper argues that if conclusions about children's grasp of logical concepts are to be reached and acceptable lines of research followed, then more precise definitions of the concept "logical necessity" must be formulated. The paper defines logical necessity as "the unconditional guarantee of truth that accompanies valid…

To determine concept usage performance of the mentally handicapped when confronted with familiar items used in the concept usage tasks, 32 common concepts were presented to 25 educable mentally handicapped and 22 non-retarded subjects. From the responses to this number of referents task, a concept usage task was constructed which required choosing…

The building block theory of language structure, an information processing approach, is applied to the development of a model of the reading process. Specifically, the model is concerned with the amount of time an individual will spend reading and the amount of content he will decode which is determined by a series of cognitive processes involving…

Sixty graduate students sorted stories according to three dimensions for classifying analogies: (1) physical similarity; (2) similarity in goals; and (3) whether the analogy leads to a reformulation of the question. High interrater agreement supports the use of the three dimensions to understand earlier inconsistent results in analogical problem…

The goal of this unified theory of human reasoning is to specify what constitutes reasoning and to characterize the psychological distinction between inductive and deductive reasoning. The theory views reasoning as the controlled and mediated application of three processes (encoding, comparison and selective combination) to inferential rules. (JAZ)

Explains the theoretical positions of Russian Marxist psychologist and educator, L. S. Vygotsky, and their philosophical foundations. Discusses Vygotsky's major psychological theories regarding cognitive development, the development of scientific and spontaneous concepts, the zone of proximal development, and language's relationship to thought.…

Because university teachers tend to be intellectually lazy and avoid sound, rigorous thought, it is emphasized that they should weigh evidence, assess arguments fairly, and take a partial stand on values and philosophies they hold. (ND)

Reports on an experiment in which performance on abstract and concrete sentences was compared in a sentence meaning classification task and in a free recall task. Results show that concrete sentences were classified significantly faster than abstract ones. (CLK)

American thought has contained a strong metaphysical bias favoring a realist interpretation of the world, and this has led to the assumption that facts possess ontological status, however, facts are segments of human experience and students must acquire conceptual tools for extracting factual data from experience.
