This study evaluated a microswitch to increase vocalization responses in individuals with multiple disabilities. The intervention successfully enhanced vocalizations, highlighting its potential for intervention programs.

Area of Science:

  • Assistive technology research
  • Augmentative and Alternative Communication (AAC)
  • Disability studies

Background:

  • Individuals with multiple disabilities often face communication challenges.
  • Vocalization responses can serve as a foundational communication method.
  • Evaluating assistive technology is crucial for enhancing communication in this population.

Purpose of the Study:

  • To extend the evaluation of a specialized microswitch.
  • To assess the microswitch's efficacy in promoting vocalization responses.
  • To investigate the use of this technology with individuals with multiple disabilities.

Main Methods:

  • An ABAB single-subject design was employed for one participant.
  • An AB single-subject design was used for the second participant.

  • Microswitch activation during the treatment phase triggered preferred environmental stimulation.

    • Main Results:

    • Both participants demonstrated an increased frequency of vocalization responses during the treatment phase.
    • The microswitch intervention proved effective in enhancing vocalizations.
    • Consistent increases in vocalization frequency were observed across both participants.

    Conclusions:

    • The specialized microswitch is a viable tool for increasing vocalization responses in individuals with multiple disabilities.
    • The findings support the integration of simple vocalization responses into intervention programs.
    • Methodological considerations for future research and application were discussed.
