The present study evaluated the effectiveness of noncontingent reinforcement combined with extinction in the treatment of perseverative speech of an 11-year-old boy with autism spectrum disorder. Following a functional analysis that suggested perseverative speech was maintained by attention, treatment was introduced and consisted of delivering attention on a fixed-time schedule and placing perseverative speech on extinction. The intervention resulted in a 98.5% decrease in perseverative speech, which maintained over a 28-month period.
