Concept learning and feature interpretation

Models of categorization often assume that people classify new instances di rectly on the basis of the presented, observable features. Recent research, however, has suggested that the coherence of a category may depend in part on more abstract features that can link together observable features that might otherwise seem to have little similarity. Thus, category learning may also involve the determination of the appropriate abstract features that u nderlie a category and link together the observable features. We show in fo ur experiments that observable features of a category member are often inte rpreted as congruent with abstract features that are suggested by observabl e features of other highly available category members. Our discussion focus es on the implications of these findings for future research.
