Less is More: Stimulus Feedback Co-Occurence in Perceptual Category Learning

Year: 2009

Type: article

Abstract: This study examined the effects of stimulus-feedback cooccurrence on rule-based and information-integration category learning.Rule-based categories are those for which a verbalizable rule is optimal.Information-integration categories are those for which the optimal rule is nonverbalizable.Participants performed a rule-based or an information-integration task where the stimulus co-occurred with the feedback (Stimulus Present) or was removed prior to feedback presentation (Stimulus Absent).Previous research examining the neural substrates of rule-based and information-integration category learning suggests that stimulus-feedback co-occurrence should support rule-based learning, but should harm information-integration learning because it will increase the prevalence of rule use.This prediction was confirmed in the current study.Implications for theories of category learning are discussed.
