The effect of a fixed-time (FT) schedule involving the delivery of preferred stimuli prior to the issuance of a low-probability instruction was evaluated with 2 young children with autism. The FT schedule was introduced according to a reversal design with 3 target instructions, 1 for the first child and 2 for the second child. Compliance increased for 2 of the 3 cases. A high-probability instruction sequence and guided compliance were implemented for the second instruction targeted for 1 child, with compliance increasing with guided compliance. (Contains 1 figure.)
