Semantic similarity between concrete and abstract cue words and free association words was measured for aphasic subjects with left perisylvian lesions using a semantic space model. Aphasic participants showed more atypical associations the more abstract the cue words were. They also generally produced less abstract words than control subjects. The results support models assuming that the meanings of concrete words are represented in bi-hemispheric networks of semantic features in the brain, whereas the representation of abstract words is more dependent on the left perisylvian language network.
