Cognitive and Instructional Theories of Impasses in Learning. Final Report.
Lesgold, Alan M.; And Others
This is the final report of a series of 19 experiments designed to study impasses in the learning of skills with a strong perceptual component. Several series of experiments were designed with the purpose of producing experimentally manipulable impasses or plateaus in the course of learning. Over 200 subjects (humans and animals) in learning studies identified targets in various complex computer-presented displays. Among the factors manipulated were: (1) complexity; (2) noise; (3) salience; (4) biasing instructions; and (5) the distribution of target features across boundaries of displays. Impasses were produced, but patterns of impasse phenomena were not reproduced reliably enough to support or disconfirm a theory of impasses in learning. It is suggested that the best available tools for studying impasses in learning are probably the tools of comparative expertise (expert-novice) research, rather than those of the learning study. Five figures supplement the text. (Author/SLD)
