Abstract

Two experiments were conducted to investigate the nature of category typicality in well defined categories in patients with aphasia: (a) an online category verification experiment, and (b) a naming treatment experiment. Results of the online category verification experiment illustrated that atypical shapes were consistently more difficult to judge than typical examples and other atypical examples (females, body parts). Results of the treatment experiment showed that training atypical examples of shapes and their semantic features resulted in generalization to naming of typical examples of the category in two patients. Training typical examples and their semantic features, however, did not result in generalization to atypical examples in one participant.
