Use of a Concurrent Operants Paradigm to Evaluate Positive Reinforcers during Treatment of Food Refusal
University of Iowa The authors evaluated the responsiveness of 4 preschool-aged children to positive reinforcers within a concurrent operants paradigm during mealtimes. The children were presented with two identical, concurrently available sets of food. Each set differed in quantity and quality of positive reinforcement paired with acceptance of each bite of food or in the number of bites of food required to obtain positive reinforcement. Experiment 1 evaluated 1 childs responsiveness to positive reinforcement while permitting escape from bite offers. Experiment 2 evaluated 2 childrens responsiveness to positive reinforcement when escape extinction occurred. Results from these experiments suggested that the children were responsive to positive reinforcers and chose more often the bites paired with the greater quantity and/or quality of reinforcement. Experiment 3 evaluated 1 childs responsiveness to positive reinforcement both without and with escape extinction. Results suggested that positive reinforcement affected choice behavior and that escape extinction affected amount of food consumed.
