Abstract:
The present study evaluated the effects of reinforcer magnitude and quality on preference for continuous and discontinuous arrangements. Two preschool children with autism spectrum disorder (ASD) participated in the study. Both participants initially preferred a discontinuous arrangement when choice options included the same quality and magnitude reinforcers; however, magnitude and quality manipulations resulted in a change in preference for continuous arrangements.
