Central auditory function in stutterers

J W Hall, J Jerger

    Journal of Speech and Hearing Research
    |June 1, 1978

    Summary
    This summary is machine-generated.

    This study found that people who stutter have central auditory processing deficits, particularly in brainstem function. These subtle auditory processing issues may contribute to stuttering.

    Area of Science:

    • Audiology
    • Neuroscience
    • Speech-Language Pathology

    Background:

    • Stuttering is a complex speech disorder.
    • Central auditory processing plays a role in speech perception and production.
    • Previous research has explored links between auditory function and stuttering with mixed results.

    Purpose of the Study:

    • To investigate central auditory function in individuals who stutter.
    • To compare the performance of stutterers and non-stutterers on a battery of auditory tests.
    • To identify potential auditory processing deficits associated with stuttering.

    Main Methods:

    • 10 individuals who stutter and 10 non-stutterers were assessed.
    • Seven audiometric procedures were used, including acoustic reflex measures and speech perception tests under various listening conditions.

  • Tests included: acoustic reflex threshold, acoustic reflex amplitude function, performance-intensity functions for words and synthetic sentences, and dichotic listening tests (Synthetic Sentence Identification with Ipsilateral/Contralateral Competing Message, Staggered Spondaic Word test).
  • Main Results:

    • Stutterers performed significantly worse than non-stutterers on the acoustic reflex amplitude function, Synthetic Sentence Identification with Ipsilateral Competing Message, and the Staggered Spondaic Word test.
    • As a group, stutterers demonstrated evidence of central auditory deficiency.
    • The pattern of deficits suggests a potential issue at the brainstem level of auditory processing.

    Conclusions:

    • Individuals who stutter may exhibit central auditory processing deficiencies.
    • These deficits appear to be subtle and may involve brainstem auditory pathways.
    • Further research is warranted to understand the precise nature and implications of these auditory processing differences in stuttering.
