This analysis of solutions to the Tower of Hanoi Problem underscores the importance of subject-by-subject analysis of "What is learned" in understanding human behavior in problem-solving situations, and provides a technique for describing subjects' task performance programs in detail. (Author/BJG)

This paper provides experimental demonstration of remindings during learning and examines their effect on performance, as well as effects of practice and difficulty. Three experiments examining the occurrence, effects, and conditions of remindings are presented, and the implications for theories of cognitive skill learning are discussed.…

A formal theory of human understanding was developed and embodied in a computer program, UNDERSTAND, which simulates the understanding processes. Due to the number of alternative processing choices, some assumptions were made which are analyzed based on their validity. (Author/DEP)

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…

Two experiments, with 300 adult women as subjects, studied the effects of laboratory training on the use of the Conjunction Rule, a principle of probability that is often violated. Learning alternative strategies enabled trained subjects to use extensional reasoning rather than intensional heuristics. (SLD)

Mismatch between gesture and speech was used to study cognitive processes that characterize the transition between incorrect, but rule-governed, problem understanding to correct rule-governed understanding among 90 fourth graders in Chicago (Illinois). Data support the idea that the transitional state is characterized by concurrent activation of…
