Abstract

Previous research in Greek aphasia has indicated that functional categories related to verb inflection are differentially impacted, with Aspect most severely affected, Agreement least affected, and Tense occupying an intermediate position. However, research materials were not controlled for overall length or position of the verb within the sentence, confounding functional category with processing load. Using balanced materials, here we tested ten persons with aphasia and ten matched control participants on grammaticality judgment and sentence completion in three functional categories (agreement, tense, and aspect) using ten verbs spanning a range of familiarity. Production results indicated no difference in errors of either lexeme or inflectional morpheme selection. In grammaticality judgment acceptance of incorrect sentences was lower for Agreement but this pattern was mirrored in the control group as well. The results provide no basis to support a specific linguistic deficit in the representation of functional categories in Greek persons with aphasia.
