    Area of Science:

    • Neurolinguistics
    • Psycholinguistics
    • Cognitive Science

    Background:

    • Aphasia, resulting from brain damage, affects language abilities.
    • Broca's aphasia and Wernicke's aphasia represent distinct patterns of language impairment.
    • Syntactic competence is crucial for understanding sentence structure.

    Purpose of the Study:

    • To investigate the hierarchy of comprehension difficulty in individuals with Broca's aphasia and Wernicke's aphasia.
    • To explore the accessibility of syntactic competence in different aphasia types.
    • To examine the role of the Minimal Distance Principle in sentence recognition.

    Main Methods:

    • Administered a broad-ranging comprehension test to Broca's aphasics, Wernicke's aphasics, and a control group.
    • Analyzed comprehension scores to identify patterns of difficulty.
    • Correlated test results with age and educational level.

    Main Results:

    • A consistent hierarchy of comprehension difficulty was observed across all groups.
    • The findings support the hypothesis that syntactic competence remains accessible in both Broca's and Wernicke's aphasia.
    • The Minimal Distance Principle, while not directly confirmed by scores, showed correlations with study variables and demographic factors.

    Conclusions:

    • Syntactic competence is not entirely lost in Broca's and Wernicke's aphasia.
    • Comprehension difficulties in aphasia follow a predictable pattern.
    • Age and education may influence sentence recognition in individuals with aphasia.
