Post stroke brain damage can affect the semantic system. This happens particularly in aphasic patients. The aim of this paper is to analyze in such patients the processing of two types of conceptual relations: taxonomic and thematic. We administered a series of tasks to assess the ability to establish and recognize conceptual relations by means of verbal and pictorial presentation. The results indicated that patients with non-fluent aphasia have greater difficulty recognizing the thematic relations, whereas fluent aphasics have greater difficulty in tasks requiring the recognition and establishment of taxonomic relationships. These results support the dissociation of both types of conceptual relations not only with respect to their modes of processing but also in its neuroanatomical substrate. In turn, the results pro-vide information regarding the dissociation between a conceptual and a linguistic system. They also show the difference that can be seen according to the type of task (free choice vs. forced choice).

Keywords : aphasia; conceptual relations; semantics.
