In this work the production deficits in the speech of three agrammatic patients have been analyzed according to the frame of the Tree Pruning Hypothesis. In the cases of a severe aphasia, tense inflection and agreement nodes are both impaired and the verb fails to raise, remaining uninflected. Therefore, the main verbs are mostly produced as infinitives or past-participle forms in absence of a auxiliary, resulting in agrammatical strings; because of the impossibility to raise and pick up the tense and agreement features, the past participle is often realized as an unmarked form (masculine and singular). When the auxiliaries are effectively realized, it is possible to note a wrong agreement marked on the auxiliary itself or on the participial form, showing again a difficulty in verb raising.

Abstract

In this work the production deficits in the speech of three agrammatic patients have been analyzed according to the frame of the Tree Pruning Hypothesis. In the cases of a severe aphasia, tense inflection and agreement nodes are both impaired and the verb fails to raise, remaining uninflected. Therefore, the main verbs are mostly produced as infinitives or past-participle forms in absence of a auxiliary, resulting in agrammatical strings; because of the impossibility to raise and pick up the tense and agreement features, the past participle is often realized as an unmarked form (masculine and singular). When the auxiliaries are effectively realized, it is possible to note a wrong agreement marked on the auxiliary itself or on the participial form, showing again a difficulty in verb raising.
