Summary
Agrammatic aphasics and children struggle with verb movement in matrix clauses, performing well on embedded clauses. This suggests verb movement, not inflection, is the core issue in their language production.
Area of Science:
- Linguistics
- Psycholinguistics
- Neurolinguistics
Background:
- Agrammatism in aphasia and child language acquisition present similar linguistic challenges.
- Verb movement is a key syntactic process in sentence formation.
Purpose of the Study:
- To investigate verb movement deficits in Dutch agrammatic aphasics and children.
- To compare performance on matrix and embedded clauses requiring different verb movement operations.
Main Methods:
- A sentence completion experiment was conducted with 6 Dutch agrammatic aphasics and 21 Dutch-speaking children.
- Participants completed sentences involving matrix clauses (requiring verb movement) and embedded clauses (not requiring verb movement).
Main Results:
- Both agrammatic aphasics and children demonstrated significantly better performance on embedded clauses compared to matrix clauses.
- A 50% failure rate was observed in matrix clause completion for both groups, indicating a specific difficulty with verb movement.
Conclusions:
- The primary linguistic deficit in both agrammatism and child language acquisition, concerning verb production, is related to verb movement, not verb inflection.
- While both groups avoid verb movement, they employ distinct compensatory strategies.
