Contingency Management Positive Reinforcement, Contracting, and Token Economies
Contingency Management • Contingency • a precise definition of the limits and range of response topographies that will produce • a specified consequence and • the environmental situation • Management • external control of events • Contingency Management • the external management of environmental stimuli that serve as reinforcers for behavioral performance
Positive Reinforcement • 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
Essential Rules when using Positive Reinforcement • FIRST • when a child is initially exhibiting a new appropriate behavior, it must be positively reinforced each time it occurs • SECOND • once the target behavior is established at a satisfactory rate, the child should be reinforced intermittently
Shea & Bauer, 1987 Steps in the Use of Positive Reinforcement • Carefully select a target behavior (do not attempt to reinforce every positive behavior a child exhibits • Observe the child's behavior to ascertain when he or she engages in the behavior • During the initial stage, reinforce the behavior immediately after it is exhibited • Specify for the child the behavior that is being reinforced • When reinforcing, speak with enthusiasm and show interest in the child's behavior • When appropriate, the practitioner may become involved in the child's behavior, that is, give the child help • Vary the reinforcer
Contingency or Behavioral Contract • an agreement that specifies a contingent relationship between the completion of a specified behavior and access to, or delivery of, a specified consequence • quid pro quo agreements • explicit and negotiated • verbal or written
Basic Components of a Contract • Task • who • what • when • Consequence • who • what • after • how much • Task Record

How do Contracts Work • Positive Reinforcement • addition of something wanted • Negative Reinforcement • removal of something not wanted • Rule-Governed Behavior • specificity generalizes to reality
Desirable Aspects of Contingency Contracting • a positive reward-based management system • a way for teachers to individualize contingencies • help teachers and parents remain consistent • a good method for involving parents and significant others in the student's program • encourages active participation and self-determination by the student • can be used to teach independence and self-control • a fairly simple behavior change intervention that can be implemented by non professionals • participants usually like it
Essential Elements of a Contract • Task description is present • Described task is observable • When the task will be accomplished is indicated • How much of the task or how well a task will be performed is indicated • Reward description is present • When the reward will be delivered is indicated • How much of the reward will be delivered is indicated • Reward is indicated to occur at a time after the task has been completed • Amount of reward is appropriate for the task
Token Economy • behaviors to be reinforced are identified and defined • a medium of exchange is selected; that medium of exchange is a symbol called a "token" • backup reinforcers are provided that can be purchased or exchanged with the token
Tokens • function as "generalized conditioned reinforcer" • paired with a wide variety of backup reinforcers • token generalized to reinforcer - not the behavior or setting • used to bridge the "time gap" between performance and reinforcement • used to bridge the "setting gap" between the delivery of reinforcement and behavior performance area
Rules for Establishing a Token Economy • Select a target behavior • Conceptualize and present the target behavior as a "what to do" not "what not to do" • Post the rules and review them frequently • Select an appropriate token • Establish reinforcers for which reinforcers can be exchanged • Develop a reward menu and post it. Include exchange ratio. • Implement the token economy on a limit basis initially. • Provide immediate reinforcement for acceptable behavior • Gradually change from a continuous to a variable schedule of reinforcement • Provide times for students to exchange tokens for rewards • Revise the reward menu frequently: Content and Ratio
Procedures for Implementing a Token Economy • Selecting Tokens • Defining Rules and Behaviors • observable, measurable, criteria for successful completion, easy to hard, prerequisite skills • Select Backup Reinforcers • naturally occurring activities • artificial activities - tangible items • Establish Ratio of Exchange • Establish General Procedures • Field Test
