Description: This is a systematic review of studies assessing the patterns of irregular and regular verb use in individuals with aphasia. The evidence from this review seems to indicate that there is no consistent pattern of dissociation between regular and irregular verbs in people with Broca's aphasia. Mixed findings were reported for irregular and regular verb use in sentence production and word repetition.
- Do regular and irregular verbs dissociate consistently in a single direction in patients with Broca's aphasia?
- What variables are likely to result in dissociations?
Population: Patients described as non-fluent, agrammatic, or Broca's aphasic
Number of Studies Included: 15
Years Included: 1980 - October 2006
The evidence from this review seems to indicate that there is no consistent pattern of dissociation between regular and irregular verbs in people with Broca's aphasia.
