A teacher in a special education classroom was working with a child with severe intellectual disability. The teacher was using small bites of food as reinforcers in a training program to help the child make correct letter discriminations. The teacher decided to arrange an establishing operation that would make food a more powerful reinforcer so that the child would be more likely to respond correctly in training sessions. Because training sessions were in the early afternoon, the teacher decided to keep the child from eating lunch at noon. The teacher reasoned that if the child did not eat lunch, food would be a more effective reinforcer in the afternoon. What is wrong with this antecedent control strategy? What would be a better antecedent control strategy to use in this case?
