Abstract

We present a study of 13 patients with aphasia, not screened by presumed subtype, showing strong correlations among disparate measures of fluency and measures of receptive and expressive grammatical ability related to verb functional categories. The findings are consistent with a single underlying dimension of severity. We sug-gest that subtyping be re-examined in light of performance patterns and only ac-cepted when patient clustering is empirically derived and theoretically meaningful.
