Functional analyses were conducted to identify reinforcers for noncompliance exhibited by 3 young children. Next, the effects of three antecedent-based interventions--noncontingent access to a preferred item, a warning, and a high-probability instructional sequence--were examined. The high-probability instructional sequence was effective for 1 child. Antecedent interventions were ineffective and extinction was necessary for the other 2 children. (Contains 1 figure.)
