Chapter 15 Differential Reinforcement Differential Reinforcement of Alternative Behavior DRA is a behavior procedure used to increase the frequency of a desirable behavior and to decrease the frequency of undesirable behaviors The desirable behavior is reinforced each time it occurs results in an increase in the future probability of the desirable behavior At the same time, any undesirable behaviors that may interfere with the desirable behavior are not reinforced results in a decrease in the future probability of the undesirable behaviors Thus, DRA involves combining reinforcement for desirable behavior and extinction of undesirable behaviors When to use DRA o Answer these three questions: Do you want to increase the rate of a desirable behavior? Is the behavior already occurring at least occasionally? Do you have access to a reinforcer that you can deliver after the occurrence of the behavior? How to use DRA o Define the desirable behavior Identify and define the desirable behavior that you plan to increase with DRA o Define the undesirable behaviors Identify and define the undesirable behaviors you plan to decrease with DRA o Identify the reinforcer Reinforcers may be different for different people Possibilities: (1) Use the reinforcer that is currently maintaining the undesirable behavior you already know this reinforcer is effective (2) Observe the person and note which activities or interests he or she pursues high-rate behaviors (3) Ask the person questions, or ask parents, teachers etc. (4) Use reinforcer questionnaires (5) Try out a variety of different stimuli and see which ones function as reinforcers www.notesolution.com
