Increasing Vocal Variability in Children with Autism Using a Lag Schedule of Reinforcement
Esch, John W.; Esch, Barbara E.; Love, Jessa R.
Analysis of Verbal Behavior, v25 p73-78 2009
Variability has been demonstrated to be an operant dimension of behavior (Neuringer, 2002; Page & Neuringer, 1985). Recently, lag schedules have been used to demonstrate operant variability of verbal behavior in persons with a diagnosis of autism (e.g., Lee, McComas, & Jawor, 2002). The current study evaluated the effects of a Lag 1 schedule on the vocal variability of 2 nonverbal children with a diagnosis of autism. Results showed systematic increases in variability during the Lag 1 schedule. Implications of lag schedules for speech and language training are discussed. (Contains 1 figure.)
