The immediate and subsequent effects of response-independent food delivery on problem behavior maintained by food were investigated. A functional analysis indicated that the participant's problem behavior was maintained by tangible (food) reinforcement. In a subsequent analysis, each occurrence of problem behavior produced a bite of wafer in the first and third components of mixed and multiple schedules, while either response-independent food or extinction was presented in the second component. Dense and lean schedules of food delivery were assessed. Results indicated that a very dense schedule of food nearly eliminated problem behavior, a very lean schedule of food and extinction produced substantial decreases in problem behavior, and intermediate schedules did not decrease problem behavior. Response patterns were differentiated across mixed and multiple schedule arrangements, with signaled changes in the schedules (multiple schedule) generally showing more immediate and sustained effects throughout the intervention component. Implications for interpretations of the effects of the intervention are discussed.
