The game of the name: An examination of linguistic reference after brain damage

Two aspects of naming have generally been examined in aphasics: the appreciation of a single property of a concept and the ability to use the names of fully elaborated concepts. In applying to aphasics a recently proposed model of semantic organization—one which allows the simultaneous examination of these two aspects—two studies were conducted: Anterior and posterior aphasics were asked (1) to name members of superordinate categories, their responses being converted into prototypicality scores (the degree to which a member of a category resembles an ideal member of that category) and (2) to differentiate between more or less prototypical members of a category and their superordinates. The results revealed that, while anterior and posterior aphasics differ in their use of the names representing fully elaborated concepts, these groups show no differences in terms of the appreciation of a single property of a concept. The implications of these findings for reference were discussed.
