Abstract

What is the best way to treat the verb inflection deficit that is so pervasive in agrammatic aphasia? We addressed this question in two treatment efficacy studies. Study 1, which was based on current theoretical perspectives and empirical data on agrammatism, compared the relative efficacy of two treatment types: one focused on extensive practice with morpho-phonological aspects while the other emphasized on training semantic features such as tense marking. Sentence production outcomes were significantly more superior with tense training. Study 2 investigated differences in acquisition and generalization patterns as a factor of verb type (training regular versus irregular verbs). Current psycholinguistic perspectives on the lexical representation of verbs coupled with the complexity account of treatment efficacy (CATE) predicts more favorable outcomes from training irregular verbs compared to regular verbs.
