Reinforcement TheoryReinforcement Theory
• Definition: a consequence that increases Definition: a consequence that increases likelihood of responselikelihood of response
– positive: application of pleasantpositive: application of pleasant
– negative: removal of aversivenegative: removal of aversive
• Types of reinforcers:Types of reinforcers:
– PositivePositive
– AversiveAversive

Behavior ModificationBehavior Modification• Identify behaviors that are CLEARLY related to performanceIdentify behaviors that are CLEARLY related to performance
• Measure natural occurrence of behavior across timeMeasure natural occurrence of behavior across time
• Identify events that precipitate the behavior as well as the Identify events that precipitate the behavior as well as the consequences of the behaviorconsequences of the behavior
• Develop an intervention strategy:Develop an intervention strategy:
– Pick reinforcer(s)Pick reinforcer(s)
– Decide on a schedule of reinforcementDecide on a schedule of reinforcement
– Implement scheduleImplement schedule
– Chart behavior change over timeChart behavior change over time
– Revise strategy if necessaryRevise strategy if necessary
• Assess behavioral changeAssess behavioral change

Maximizing the EffectivenessMaximizing the Effectiveness of Reinforcement of Reinforcement• More likely to work when:More likely to work when:
– Rewards are valued (give CHOICE!)Rewards are valued (give CHOICE!)
– Regular feedback on performanceRegular feedback on performance
– Reward closely follows desired behaviorReward closely follows desired behavior
– Person knows what is expected and how they will be rewardedPerson knows what is expected and how they will be rewarded
– Rewards are administered fairly and consistentlyRewards are administered fairly and consistently
• Common Problems:Common Problems:– Reinforcement not immediateReinforcement not immediate
– Reinforcement is non-contingentReinforcement is non-contingent
– Reward is not powerful enoughReward is not powerful enough
– Inconsistent distributionInconsistent distribution
