Adults with persistent developmental stuttering (PDS) show altered brain responses to speech sounds, not simple tones. This auditory processing difference may explain their speech disorder.

Area of Science:

  • Neuroscience
  • Speech and Hearing Science

Background:

  • Persistent developmental stuttering (PDS) is a speech disorder affecting adults.
  • Auditory perceptual deficits have been investigated as a potential contributing factor in PDS.

Purpose of the Study:

  • To investigate auditory perceptual deficits in adults with PDS.
  • To determine if neural responses to speech sound contrasts differ between individuals with PDS and fluent controls.

Main Methods:

  • Compared mismatch negativity (MMN) event-related potentials.
  • Tested responses to simple tone (frequency, duration) and phonetic contrasts.
  • Used paired fluent control subjects for comparison.

Main Results:

  • Individuals with PDS exhibited normal MMN to simple tone contrasts.

Related Experiment Videos

  • A significant left-lateralized enhancement of MMN to phonetic contrasts was observed in PDS.
  • Enhanced MMN to phonetic contrasts positively correlated with self-rated speech disfluency.

    • Conclusions:

    • Adults with PDS possess abnormal neural traces for speech sounds.
    • Altered speech sound representation in the auditory cortex may underlie stuttering.
    • The findings highlight the role of speech perception mechanisms in speech production.
