Comprehending homographs in aphasia.

R S Pierce

    Brain and Language
    |July 1, 1984
    PubMed
    Summary

    Aphasic individuals struggle accessing multiple meanings of homographs compared to typical subjects. Meaning typicality, not number of meanings or aphasia type, affected access.

    Area of Science:

    • Neurolinguistics
    • Psycholinguistics
    • Cognitive Psychology

    Background:

    • Aphasia, a language disorder post-brain damage, often impairs semantic processing.
    • Homographs, words spelled identically but with different meanings, present a challenge for semantic access.

    Purpose of the Study:

    • To investigate the semantic knowledge of homographs in individuals with aphasia.
    • To compare homograph meaning accessibility between aphasic and normal subjects.

    Main Methods:

    • Assessed 13 individuals with aphasia on their knowledge of multiple homograph meanings.
    • Correlated performance with auditory comprehension and picture naming abilities.

    Main Results:

    • Aphasic subjects showed reduced availability of multiple homograph meanings compared to controls.
    • Less typical meanings were less accessible; aphasia type and homograph meaning count did not impact performance.
    • Performance correlated significantly with auditory comprehension and picture naming.

    Conclusions:

    • Semantic organization in aphasia affects the accessibility of word meanings, particularly less typical ones.
    • Auditory comprehension and naming abilities are linked to semantic processing of polysemous words.
