Impact of intervening learning on resurgence in humans with Autism Spectrum Disorders.
In the present study, we investigated the degree to which responding would resurge in children diagnosed with Autism Spectrum Disorders (ASD) following an intervening training period comprising different schedules of reinforcement. Twenty-four children of the ages 7-15, with a diagnosis of an ASD, were taught a play a sequence on a variable ratio- (VR) 3 schedule of reinforcement, during a 30-min session. The play sequence was then extinguished before the participants were taught a second play sequence, using a VR-4 schedule for 30 min, a VR-4 schedule for 60 min, or a VR-2 schedule for 30 min. A 5-min extinction session was then conducted to determine the impact that the intervening schedules had on the resurgence of the original behavior. The original sequence resurged to a greater extent for Group VR-4 30 min than it did for the other two groups. The results provide evidence that the length of time between initial training and testing is not a prime determinant of the level of resurgence, but that the amount of conditioning may play a stronger role: The greater the number of reinforcers received, the smaller the resurgence effect.
