1. Contingency Management Positive Reinforcement, Contracting, and Token Economies

2. Contingency Management n Contingency – a precise definition of the limits and range of response topographies that will produce – a specified consequence and – the environmental situation n Management – external control of events n Contingency Management – the external management of environmental stimuli that serve as reinforcers for behavioral performance

3. Contingent Positive Reinforcement

4. Positive Reinforcement n The process of reinforcing an appropriate target behavior in order to increase the probability that the behavior will recur – it is responsive to the child's natural need for attention and approval – it decreases the probability that the child will exhibit inappropriate behavior in an effort to obtain needed attention

5. Essential Rules when using Positive Reinforcement n FIRST – when a child is initially exhibiting a new appropriate behavior, it must be positively reinforced each time it occurs n SECOND – once the target behavior is established at a satisfactory rate, the child should be reinforced intermittently

6. Steps in the Use of Positive Reinforcement l Carefully select a target behavior (do not attempt to reinforce every positive behavior a child exhibits l Observe the child's behavior to ascertain when he or she engages in the behavior l During the initial stage, reinforce the behavior immediately after it is exhibited l Specify for the child the behavior that is being reinforced l When reinforcing, speak with enthusiasm and show interest in the child's behavior l When appropriate, the practitioner may become involved in the child's behavior, that is, give the child help l Vary the reinforcer Shea & Bauer, 1987

7. Contingency or Behavioral Contract

8. n an agreement that specifies a contingent relationship between the completion of a specified behavior and access to, or delivery of, a specified consequence n quid pro quo agreements n explicit and negotiated n verbal or written

9. Basic Components of a Contract n Task – who – what – when n Consequence – who – what – after – how much n Task Record

10. contract This is to certify that: George Haus Will: complete and turn in his daily in-school spelling exercise. For completing: completion of work - 100 pts. on-time turning work in - 100 pts. grade of 90-100% - 200 pts. 80-89% - 100 pts. 70-79% - 50 pts. 60-69% - 25 pts. 0-59% - 5 pts. Points may be spent on FRIDAY of each week. ______________ teacher ______________ student ______________ contract dates official George Haus Mr. Bingo Jan 1 - Jan 30 1,000 pts. = special privilege PASS CARD 500 pts. = Percent Ticket 100 pts. = 5 free minutes

11. How do Contracts Work n Positive Reinforcement – addition of something wanted n Negative Reinforcement – removal of something not wanted n Rule-Governed Behavior – specificity generalizes to reality

12. Desirable Aspects of Contingency Contracting l a positive reward-based management system l a way for teachers to individualize contingencies l help teachers and parents remain consistent l a good method for involving parents and significant others in the student's program l encourages active participation and self-determination by the student l can be used to teach independence and self-control l a fairly simple behavior change intervention that can be implemented by non professionals l participants usually like it

13. Essential Elements of a Contract l Task description is present l Described task is observable l When the task will be accomplished is indicated l How much of the task or how well a task will be performed is indicated l Reward description is present l When the reward will be delivered is indicated l How much of the reward will be delivered is indicated l Reward is indicated to occur at a time after the task has been completed l Amount of reward is appropriate for the task

14. Token Economy

15. n behaviors to be reinforced are identified and defined n a medium of exchange is selected; that medium of exchange is a symbol called a "token" n backup reinforcers are provided that can be purchased or exchanged with the token

16. Tokens n function as "generalized conditioned reinforcer" – paired with a wide variety of backup reinforcers n token generalized to reinforcer - not the behavior or setting n used to bridge the "time gap" between performance and reinforcement n used to bridge the "setting gap" between the delivery of reinforcement and behavior performance area

17. Rules for Establishing a Token Economy l Select a target behavior l Conceptualize and present the target behavior as a "what to do" not "what not to do" l Post the rules and review them frequently l Select an appropriate token l Establish reinforcers for which reinforcers can be exchanged l Develop a reward menu and post it. Include exchange ratio. l Implement the token economy on a limit basis initially. l Provide immediate reinforcement for acceptable behavior l Gradually change from a continuous to a variable schedule of reinforcement l Provide times for students to exchange tokens for rewards l Revise the reward menu frequently: Content and Ratio

18. Procedures for Implementing a Token Economy n Selecting Tokens n Defining Rules and Behaviors – observable, measurable, criteria for successful completion, easy to hard, prerequisite skills n Select Backup Reinforcers – naturally occurring activities – artificial activities - tangible items n Establish Ratio of Exchange n Establish General Procedures n Field Test
