Differential Reinforcement Reinforcement of Incompatible Behavior
underlying principle is that you can weaken a maladaptive behavior by strengthening an alternative behavior in its place • incompatible behavior • cannot be just any behavior - it must be mutually exclusive with the maladaptive behavior or must directly compete with it (in-seat vs. out-of-seat, talking vs. not talking) • alternative or competing behavior • are not mutually exclusive - it may be possible to perform both behaviors at same time Differential Reinforcement of Alternative or Incompatible Behavior (DRA & DRI)
Advantages: • they are positive approaches to behavior reduction without any negative side effects • popular with change agents because desired behavior is increased • logical - teach what you want not get rid of what you don't want • Disadvantages: • requires a high degree of management to • establish new behavior • withhold reinforcement for maladaptive behavior DRA & DRI
student earns reinforcement for not engaging in the maladaptive behavior for a specified interval of time • may be Momentary DRO (MDRO) or Whole-Interval DRO (WDRO) • Advantages: • new behavior not established, shaping procedures available, low management • Disadvantages: • replacement behavior not specified or controlled Differential Reinforcement of the Omission of Behavior (DRO)
occurs when you withhold or remove the reinforcer maintaining a behavior • is a procedure that gradually reduces the frequency and/or intensity of a target behavior by withholding reinforcement from previously reinforced behavior • extinction can be used to eliminate the connection between the behavior and the positive consequences that follow it Extinction
Extinction REQUIRES complete control of the reinforcer • consistency is the most important factor related to the efficacy of extinction • in most cases, extinction is only effective in reducing behaviors that are motivated by attention from the teacher/parent/caregiver • Other factors affecting resistance to extinction • the schedule of reinforcement that previously maintained the behavior • the amount of strength of the previous reinforcer • the length of time of the previous behavior-reinforcer association • the frequency of use of extinction with the student: more the better Extinction (cont)
Advantages • may be effective without the use of physical or verbal consequences • no use of aversive consequences/punishment • effects tend to be long lasting • when combined with DRI or DRA very effective • Disadvantages • temporary increase in behavior expected at start • child frustration • difficult to chose appropriate behavior to use extinction with • must have consistency between and among caregivers and peers (environment) Extinction (cont)
the removal of a child from an apparently reinforcing setting to a presumable nonreinforcing setting for a specified and limited period of time • Types of time-out: • nonexclusion • time-out ribbon • planned ignoring • removal of specific reinforcers • observational • exclusion • seclusion • isolation Time-Out
Duration of time-out • 2-minutes • 4-5 maximum • never more than 10 • Caregiver must be able to clearly observe child • Child should not be able to see caregiver • Expectations for child's behavior should be clear • Set timer for amount of time child is to spend in time-outSetting should not be reinforcing - remember the purpose of time-out is to remove the child from reinforcement • Validate the reinforcement value of the "normal" environment Isolation Time-Out: Guidelines

Easy to integrate with positive reinforcement program to increase appropriate behavior • Effects of T.O. process usually rapid • Nonexclusion T.O. may be employed without removing the child • T.O. viable alternative to more intrusive behavior reduction strategies Advantages of Time Out
T.O. may be abused - duration & frequency • Caregivers may use it as a "break" • Frequent T.O. removes the child from the educational environment • Child may exhibit other inappropriate behaviors when caregivers remove positive reinforcement Potential Disadvantages of T.O.
Reasons for Punishment • Retribution • A punitive response given because it is “deserved” • Vengeance for Vengeance’ sake • Deterrence • To serve notice on potential offenders • Rehabilitation • Punishment = Treatment Grupp, S.E. (1971) Theories of Punishment. Indiana University Press: Bloomington
the addition of an aversive stimulus as a consequence of a behavior - may be physical or psychological • the subtraction of something the child perceives as desirable - response cost • punishment by deprivation or response-cost is generally considered less harmful to the child and more effective intervention than the addition of physical or psychological aversive stimuli • the short-term effectiveness of punishment for decreasing behaviors is not disputed - punishment is effective for obtaining short-term goals Punishment
Reasons for avoiding the use of punishment: • It does not eliminate but merely suppresses the behavior • It does not provide a model for the desired acceptable behavior • Aggression on the part of the practitioner presents an undesirable model • The emotional results of punishment may be fear, tension, stress, or withdrawal • The child's resulting frustration may result in further deviation • Punishment is associated with the punisher rather than with the unacceptable behavior Punishment
Commonly used punishments • denying participation in scheduled activities • denying snacks • physical punishment • verbal punishment • having the child stand apart from the others • having the child wear a sign • If punishment is to be used: guidelines to use • specify and communicate the punishable behavior to the child by means of classroom rules for behavior • post the rules where the children can see them; review them frequently • provide models of acceptable behavior • apply the punishment consistently, not whimsically • be fair in using the punishment • impose the punishment impersonally - do not punish when you are angry or otherwise out of self-control Punishment
Loss of Privileges - response cost • Guidelines • Be sure the child understands the relationship between the target behavior and the privilege to be lost • Be sure the child knows the punishable behavior and the consequence of exhibiting it • When possible use natural or logical consequences • Apply the loss of privilege interventions fairly • Avoid warning, nagging, or threatening • Do not debate the punishable behaviors, the rules, or the punishment once these have been established • Do not become emotionally involved, Don't feel guilty when the child loses a privilege • Be consistent • Reinforce appropriate behavior; do not emphasize inappropriate behaviors only Punishment
Reprimands - to be scolded, "yelled at", "bawled out", or otherwise verbally chastised for exhibiting an inappropriate target behavior • Guidelines • Be specific. Tell the child exactly what inappropriate behavior is being reprimanded • Reprimand the behavior, do not denigrate the child • Reprimand immediately • Be firm in voice and physical demeanor • If either the child or others may be harmed by the behavior, remove the child • Encourage the child to behave appropriately and include a statement of the appropriate behavior in the reprimand • Be calm • When it is over, it is over. • Always observe the child's reaction to the reprimand to determine if it is aversive. Punishment
Restitution • a procedure that requires and individual to return the environment to its state prior to a behavior that changed the environment • Restitutional Overcorrection • the child is not only required to perform restitution but to "restore the situation to a state vastly improved from that which existed before the disruption."
