1 Chapter 15: Punishment by Removal of a Stimulus
Cooper, Heron, and Heward Applied Behavior Analysis, Second Edition

2 Definition of Punishment by Removal of a Stimulus
Stimulus removed Contingent upon a response That decreases the future probability of that response The future decrease in the response is a critical feature in defining punishment Cooper, Heron, and Heward Applied Behavior Analysis, Second Edition

3 Punishment by contingent removal of a stimulus
Future Frequency Stimulus Change Stimulus Applied Stimulus Removed Behavior is reduced Type I Positive Punishment Type II Negative Punishment Cooper, Heron, and Heward Applied Behavior Analysis, Second Edition

4 Adult places child in time out (peer attention is removed)
Example EO Child is participating in classroom buddy activities, where attention from peers (a positive reinforcer) is available. SD Adult says, “Let’s open our books to page 12. Each of you should read the first paragraph to your buddy.” Response Child pokes his buddy SR- Adult places child in time out (peer attention is removed) Poking a buddy occurs less often in the future when the teacher gives a classroom instruction and peer buddies are available. Cooper, Heron, and Heward Applied Behavior Analysis, Second Edition

5 Time-out from Positive Reinforcement
The withdrawal of the opportunity to earn positive reinforcement, or The loss of access to reinforcers for a specified period of time Contingent upon the occurrence of a target behavior If the effect of these is to decrease the future probability of the behavior, then this procedure has functioned as a punisher for the behavior Cooper, Heron, and Heward Applied Behavior Analysis, Second Edition

6 Important Aspects of Time-out
The discrepancy between “time-out” and “time-in” must be great The loss of access to reinforcement must be contingent upon a target behavior There is a resultant decrease in the future probability of the behavior (otherwise it is likely not time out from reinforcement because the EO that preceded the behavior was not a reinforcing, “time-in” environment) Cooper, Heron, and Heward Applied Behavior Analysis, Second Edition

7 Time-out Procedures Nonexclusion Exclusion Planned ignoring
Withdrawal of a specific positive reinforcer Contingent observation Time-out ribbon Exclusion Time-out room Partition time-out Hallway time-out Cooper, Heron, and Heward Applied Behavior Analysis, Second Edition

8 Nonexclusion Time-out
The individual is not completely removed physically from time-in setting However, position within the environment may shift Cooper, Heron, and Heward Applied Behavior Analysis, Second Edition

9 Planned Ignoring Social reinforcers--usually attention, physical contact, or verbal interaction--are removed for a brief period Systematically looking away from the student Remaining quiet Refraining from any interaction for a specified period of time Planned ignoring is Nonintrusive Quick Convenient Cooper, Heron, and Heward Applied Behavior Analysis, Second Edition

10 Withdrawal of a Specific Positive Reinforcer
Some sort of positive reinforcer that is already present is removed for a brief period of time contingent upon a target behavior, and then reinstated Can be implemented as a group contingency Cooper, Heron, and Heward Applied Behavior Analysis, Second Edition

11 Contingent Observation
The individual is repositioned within the existing setting Observation of ongoing activities is still possible Access to reinforcement is lost, however Cooper, Heron, and Heward Applied Behavior Analysis, Second Edition

12 Time-out Ribbon A colored band is placed on the child’s wrist and is discriminative for receiving reinforcement Child earns reinforcers when it is on Contingent upon a target behavior, the colored band is removed for a specified period of time All social interaction is terminated Other reinforcers are also withheld Cooper, Heron, and Heward Applied Behavior Analysis, Second Edition

13 Exclusion Time-out The individual is removed, physically, from the environment for a specified period of time Contingent upon the occurrence of a target behavior Time-out room Separated by partition Placed in hallway Cooper, Heron, and Heward Applied Behavior Analysis, Second Edition

14 Time-out Room A confined space outside the individual’s normal educational or treatment environment It is devoid of any positive reinforcers; also minimally furnished It is safe (adequate heat and light), secure (but not locked) and temporary Near time-in setting Cooper, Heron, and Heward Applied Behavior Analysis, Second Edition

15 Advantages of Time-out Rooms
Opportunity to acquire reinforcement is eliminated or reduced substantially After a few exposures, students learn to discriminate it from other rooms (making the time-in setting more desirable) Decreases risk of student hurting other students Cooper, Heron, and Heward Applied Behavior Analysis, Second Edition

16 Disadvantages of Time-out Rooms
Must escort students to time-out May result in resistance, emotional outbursts Access to ongoing instruction is prohibited Individuals may engage in behaviors (e.g., self-injury) that should be stopped but go undetected Negative public perception Cooper, Heron, and Heward Applied Behavior Analysis, Second Edition

17 Partition Time-out Individual remains in time-in setting, but his view within the setting is restricted by a partition, wall, or cubicle Advantage: Keeps individual in instructional setting Disadvantages: Individual still may be able to obtain covert reinforcement, negative public perception Cooper, Heron, and Heward Applied Behavior Analysis, Second Edition

18 Hallway Time-out Individual sits in hallway outside of classroom or treatment area Not highly recommended strategy Individual can obtain reinforcement from a multitude of sources Child can escape easily Cooper, Heron, and Heward Applied Behavior Analysis, Second Edition

19 Desirable Aspects of Time-out
Ease of application (especially nonexclusion time-out) Acceptability (especially nonexclusion) Rapid suppression of problem behavior Easily combined with other procedures, such as differential reinforcement Cooper, Heron, and Heward Applied Behavior Analysis, Second Edition

20 Effective Use of Time Out
Reinforce and enrich the time-in environment Utilize differential reinforcement to reinforce alternative and incompatible behaviors Clearly define the behaviors leading to time-out All parties (including the target individual) should have explicit, observable definitions of the problem behavior Cooper, Heron, and Heward Applied Behavior Analysis, Second Edition

21 Effective Use of Time Out
Define procedures for the duration of time-out Initial duration should be short Longer than 15 minutes ineffective Define exit criteria If individual is misbehaving when time-out ends, it should be continued until inappropriate behavior ceases Cooper, Heron, and Heward Applied Behavior Analysis, Second Edition

22 Effective Use of Time Out
Exclusion vs. nonexclusion time-out Consider institutional policies that may prevent exclusion time-out Physical factors (i.e., lack of appropriate space) may prevent exclusion time-out Explain time-out rules to the individual Target behaviors, duration, exit criteria Obtain permission Administrative approvals Parental approvals Cooper, Heron, and Heward Applied Behavior Analysis, Second Edition

23 Effective Use of Time Out
Apply consistently Evaluate effectiveness Target behavior should decrease Track frequency and duration of time outs Also track collateral behaviors for side effects Consider other options Consider legal and ethical issues Cooper, Heron, and Heward Applied Behavior Analysis, Second Edition

24 Response Cost Loss of a specific amount of reinforcement
Contingent upon a target behavior Reduces the future probability of the target behavior Examples: reclaiming awards or stickers, “fines” (e.g., loss of tokens or money) Cooper, Heron, and Heward Applied Behavior Analysis, Second Edition

25 Example EO Child has 15 minutes of recess on schedule every morning.
SD Adult says, “Let’s open our books to page 12. Each of you should read the first paragraph to your buddy.” Response Child pokes his buddy SR- 5 minutes of the recess time is removed Poking a buddy occurs less often in the future when the teacher gives a classroom instruction and recess is available. Cooper, Heron, and Heward Applied Behavior Analysis, Second Edition

26 Desirable aspects of Response Cost
Produces rapid decreases in the target behavior Convenient and easy to implement (can be incorporated into existing token or allowance programs) Is easily combined with other approaches (such as differential reinforcement) Cooper, Heron, and Heward Applied Behavior Analysis, Second Edition

27 Methods of Response Cost
Direct fine Bonus response cost Combined with positive reinforcement Group arrangements Cooper, Heron, and Heward Applied Behavior Analysis, Second Edition

28 Fines Directly fine a specific amount of the positive reinforcer
Consider legal and ethical appropriateness e.g., denying access to food and free time may be unethical or undesirable Obtain permission from human rights review committees Cooper, Heron, and Heward Applied Behavior Analysis, Second Edition

29 Bonus Response Cost Make additional reinforcers available to the individual, specifically for removal during a response-cost contingency This may relieve many of the legal and ethical dilemmas involved with response cost Cooper, Heron, and Heward Applied Behavior Analysis, Second Edition

30 Combining with Positive Reinforcement
Combine with point/token programs (differential reinforcement) Advantages If all points or tokens are not lost, they can be exchanged for back-up reinforcers The use of reinforcers reduce the legal and ethical concerns Cooper, Heron, and Heward Applied Behavior Analysis, Second Edition

31 Combining with Group Contingencies
Contingent upon any member of a group, the entire group loses a specified amount of reinforcement Cooper, Heron, and Heward Applied Behavior Analysis, Second Edition

32 Effective Use of Response Cost
Specifically define the target behaviors that will result in response cost, as well as the fines Establish rules for refusals to comply with the response-cost procedure, and explain these Greater fines should be associated with more severe forms of problem behavior Be cautious of making fines so great that the individual becomes “bankrupt” Cooper, Heron, and Heward Applied Behavior Analysis, Second Edition

33 Effective Use of Response Cost
Fines should be posed immediately Response cost vs. bonus response cost Use least aversive initially (bonus response cost) Increases acceptability Decreases emotional outbursts Ensure reinforcement reserve (decrease likelihood of “bankruptcy” Cooper, Heron, and Heward Applied Behavior Analysis, Second Edition

34 Effective Use of Response Cost
Be prepared for unplanned or unexpected outcomes Response cost can reinforce rather than punish undesirable behavior Individuals can refuse to give up positive reinforcers Avoid overuse Keep records to evaluate effectiveness Cooper, Heron, and Heward Applied Behavior Analysis, Second Edition

35 Response Cost Considerations
Increased aggression may occur Ignore emotional outbursts when possible Either don’t use response cost if this is expected Or be prepared to ride out the storm Avoidance of the person who administers response cost or the setting may occur These become “conditioned aversive stimuli” Make sure positive reinforcement is available for appropriate behavior to reduce the likelihood of this outcome Cooper, Heron, and Heward Applied Behavior Analysis, Second Edition

36 Response Cost Considerations
Collateral reductions of desirable behaviors may occur Response cost may unintentionally suppress other, desirable behaviors, as well as the target problem behaviors Response cost calls attention to inappropriate behaviors Be prepared for unpredictability Cooper, Heron, and Heward Applied Behavior Analysis, Second Edition
