When More Is Less: Feedback Effects in Perceptual Category Learning
Maddox, W. Todd; Love, Bradley C.; Glass, Brian D.; Filoteo, J. Vincent
Cognition, v108 n2 p578-589 Aug 2008
Rule-based and information-integration category learning were compared under minimal and full feedback conditions. Rule-based category structures are those for which the optimal rule is verbalizable. Information-integration category structures are those for which the optimal rule is not verbalizable. With minimal feedback subjects are told whether their response was correct or incorrect, but are not informed of the correct category assignment. With full feedback subjects are informed of the correctness of their response and are also informed of the correct category assignment. An examination of the distinct neural circuits that subserve rule-based and information-integration category learning leads to the counterintuitive prediction that full feedback should "facilitate" rule-based learning but should also "hinder" information-integration learning. This prediction was supported in the experiment reported below. The implications of these results for theories of learning are discussed. (Contains 3 figures.)
