Treatment of Grammatical Time Marking in Post-Stroke Aphasia

The study aims to assess a individual or group therapy's effectiveness in grammatical time marking. The main objective is to examine whether the therapy improves grammatical time marking of inflected verbs treated on the sessions. We also explore whether the observed progress can be transferred to untrained items, more ecological contexts and if is maintained two and four weeks after the end of treatment.This therapy will be administered to nine individuals with brain lesions after stroke. Five individuals will take part of the individual therapy and four individuals will take part of the group therapy (two individuals per group). The therapy will last one month, at the rate of three weekly sessions of approximately one hour.
