Processing distinctions between stems and affixes: evidence from a non-fluent aphasic patient
Cognition
|August 1, 1990
Summary
This study shows a non-fluent aphasic patient, BN, struggles with complex word meanings due to issues accessing semantic and syntactic content of bound morphemes, not the word stems themselves.
Area of Science:
- Neuroscience
- Psycholinguistics
- Linguistic Morphology
Background:
- Investigating language processing in aphasia is crucial for understanding brain-language relationships.
- Morphologically complex words (e.g., derived, inflected) pose unique challenges for language comprehension.
Observation:
- Patient BN, with non-fluent aphasia, demonstrated insensitivity to the contextual appropriateness of derived and inflected words.
- BN could process the stems of complex words but not the bound morphemes.
Findings:
- The patient's comprehension deficit stems from impaired access to the semantic and syntactic content of bound morphemes.
- Phonological access of morphologically complex words was not impaired.
Implications:
- BN's case challenges the notion that non-fluent aphasia universally impairs syntactic aspects of morphology.
- Findings suggest separate neural representations for word stems and bound morphemes in some individuals.
