Students may engage in high rates of social approach responses at inappropriate times throughout the school day. One intervention that has been used to teach students appropriate and inappropriate times to access attention is a multiple schedule of reinforcement. In this study, we evaluated the efficacy of a multiple schedule that indicated when…

Progressive-ratio (PR) schedules were used to identify the break point (i.e., the last schedule value completed) for 2 reinforcers under single and concurrent schedules. After the respective break points were established, the same reinforcers were presented under concurrent fixed-ratio (FR) schedules that were yoked to the break points obtained…

A study of three children (ages 3-9) with severe problem behavior investigated alternatives to the typical application of noncontingent reinforcement (NCR) for problem behavior. Instead of using continuous access to reinforcers and extinction, the study found that an NCR schedule based on latency and NCR without extinction were more effective for…

The efficacy of noncontingent reinforcement with variable-time (VT) schedules was evaluated by comparing the effects of VT and fixed-time (FT) reinforcement schedules with two individuals with moderate to severe mental retardation and severe behavior problems. Both VT and FT schedules were effective in reducing problem behavior. (Contains…
