Abstract

Two individuals with Broca’s aphasia were trained on (infinitival and finite) verb production in sentence context in an experiment with a multiple baseline, multiple single-case design. Both patients improved on a related task, but no improvement was found on an unrelated test. Improvement generalized to the subtasks ‘naming’ and ‘sentence construction’ of the Aachen Aphasia Test (AAT) and on the comprehensibility scale of the Amsterdam-Nijmegen Everyday Language Test (ANELT). In spontaneous speech, the mean utterance length of both clients increased significantly. One client produced significantly more finite verbs after treatment. The other client’s number of lexical verbs increased to a normal level after treatment.
