Computer use in cognitive psychology

Abstract

Some influences of computers on theory and methodology in cognitive research are discussed. Theoretical constructs that cognitive science has borrowed from computer science include processing algorithms, processing rates, information organization, and information selection. The application of these constructs to human information processing is considered, with illustrations from memory and reading research. Further, the role of computers in research methodology is evaluated, on the basis of a comparison of 1962 and 1992 journal articles. Attributes considered include the nature of stimulus control, item content and physical features, cognitive task demands, information feedback to subjects, and assessment of individual differences in cognitive strategies. These methodological attributes are illustrated by memory and reading paradigms for which computer technology is critical. Computer science has enriched theory and data in cognitive science, but the comparison of journal articles from 1962 and 1992 suggests that many psychologists are not taking full advantage of these possibilities. © 1994 Psychonomic Society, Inc.
