Argues that the unconscious mind plays a central role in argumentation. Discusses the nature of the unconscious and analyzes invention, focusing on rules theory. Claims that argument reception is controlled by the unconscious. Identifies a series of basic issues needing investigation. (JD)

Description of expert system development focuses on identifying the problem, or knowledge, domain, and discusses three methods for defining the domain: (1) brainstorming, (2) concept analysis, and (3) information processing analysis, which describes cognitive processes. The techniques are illustrated by a description of an auto manfacturer's sales…

Illustrates distinctions among kinds of knowing. Distinguishes knowing-to from other forms of knowing, and explores implications of that distinction for teaching and learning mathematics. Proposes that knowing-to act in the moment depends on the structure of attention at the moment, and on what one is aware of. (Contains 75 references.)…

Evolution by natural selection may be characterized as a system in which a large store of genetic information will persist indefinitely while it remains coordinated with its environment but will continuously produce small random variations that are tested for environmental effectiveness. In any environment, effective variations will persist while…

Mercer, N. (1995) coined the term interthinking to link the cognitive and social functions of group talk. Essentially, interthinking means using talk to think collectively, to engage with others' ideas through oral language. In this article I share four excerpts from small group interactive read-aloud sessions that were conducted with Grade 1…

Post-formal operational thought is characterized by both relativism and dialecticism. To examine age differences across adulthood in relativistic and dialectical thought, and to determine whether formal operations are necessary but not sufficient for these forms of thought, 20 young (mean age, 19.6), 20 middle aged (mean age, 46.2), and 20 older…

A major error in cognitive science has been to suppose that the meaning of a representation in the mind is known prior to its production. Representations are inherently perceptual--constructed by a perceptual process and given meaning by subsequent perception of them. The person perceiving the representation determines what it means. This premise…

Discusses the enigma of what and how people know apparently trivial information. Presents an experiment, expected answers, and actual responses to grammar questions to determine the degree of common knowledge in professional trivia. Concludes that further research may bring a clearer understanding of the "tradition" of language teaching…

Important and recent developments in cognitive science in the areas of performance components, knowledge structures, metacomponents, and metacognition are reviewed, and a set of guidelines for educators involved in implementation or evaluation of cognitively based instructional programs are offered. (Author/DB)

Reports four experiments focusing on Piaget's claims that conservation and transitivity concepts are experienced as logically necessary truths. Two experiments examined feelings of certainty and necessity in college students presented with Piagetian tasks. Two other experiments extended these procedures to children and the issue of developmental…

A model of mental representations is developed and shown to provide a framework for interpreting research. The content of awareness is characterized as a model of the world capable of simulating future events, anticipating present events, and thereby formulating appropriate actions. Properties of awareness and of underlying processes are…

In a comparison of cognitive processes and knowledge structures of expert and novice parents, interview data and verbal records were collected during two visits to five expert and seven novice mothers of infants. Results indicate clear differences between experts and novices in goals for the child, parent role, problem solving, and cue recognition…

Reports the results of a study of 45 Ph.D. history students who were asked questions about cognitive activity related to information events based on a grounded theory approach. Topics include knowledge acquisition; information process; a situation model theory of reading comprehension; elaborative inferencing; and domain experts versus domain…

This article explores the legacy of Paul Pintrich in regard to theory and research in conceptual change. Specifically, this article reviews his vision for a view of conceptual change--a vision that integrated motivation and affect within a broader view of cognition in the classroom (Pintrich, 1999; Pintrich & Sinatra, 2003). This article describes…

The authors present 2 experiments that establish the presence of knowledge partitioning in perceptual categorization. Many participants learned to rely on a context cue, which did not predict category membership but identified partial boundaries, to gate independent partial categorization strategies. When participants partitioned their knowledge,…
