Pragmatic functions in aphasia

A M Guilford, J K O'Connor

    Journal of Communication Disorders
    |September 1, 1982
    PubMed
    Summary

    Aphasia patients, even with severe impairments, utilize pragmatic, mathetic, and informative language functions. These pragmatic behaviors persist in residual speech, offering insights for speech therapy.

    Area of Science:

    • Neurolinguistics
    • Speech-Language Pathology

    Background:

    • Aphasia, a language disorder post-brain damage, often affects communication beyond basic grammar.
    • Understanding pragmatic language use is crucial for assessing and treating aphasia.
    • Previous research highlights deficits in aphasia, but pragmatic function nuances require further exploration.

    Purpose of the Study:

    • To investigate pragmatic functions in the expressive speech of individuals with motor aphasia.
    • To analyze the presence and characteristics of pragmatic, mathetic, and informative functions in aphasic speech.
    • To explore the relationship between aphasia severity and the clustering of pragmatic functions.

    Main Methods:

    • Examined expressive speech in six individuals with aphasia (two fluent, four motor).
    • Utilized elicited conversation, picture stimulation, and unelicited conversation to elicit speech.
    • Analyzed speech for pragmatic, mathetic, and informative functions, correlating with aphasia severity.

    Main Results:

    • Pragmatic, mathetic, and informative functions were observed in the residual speech of all participants, irrespective of aphasia type or severity.
    • A clustering of pragmatic functions was evident in more severely impaired subjects.
    • Performance deficits in pragmatic behaviors were supported by the findings.

    Conclusions:

    • Individuals with aphasia retain pragmatic language abilities, demonstrating diverse functional uses of residual speech.
    • Aphasia severity correlates with the organization and manifestation of pragmatic functions.
    • Findings have clinical implications for developing targeted language elicitation and intervention strategies for aphasia.
