Use Music to Reduce Vocal Stereotypy in Individuals with Autism

Vocal stereotypy is often maintained by automatic reinforcement (although professionals should assess the individual to be sure of the function of the behavior rather than assuming that all vocal stereotypy is maintained by automatic reinforcement).
Behaviors that are maintained by automatic reinforcement can be challenging to address in a natural setting as well as in a clinical setting.
Two common intervention strategies for behaviors maintained by automatic reinforcement include:
  1. Matched stimulation (MS)
  2. Response interruption and redirection (RIRD)
MS is an antecedent intervention that provides noncontingent access to a stimulus that is presumed to be similar to the one the individual obtains from the displayed behavior.
RIRD is a consequence strategy that may be considered a punishment procedure in which the individual’s vocal stereotypy is interrupted and then the individual is required to display a number of vocal responses absent of the vocal stereotypic behavior.
