Introduction
  • Punishment is
  • Poorly understood
  • Frequently misapplied
  • Controversial
  • Will you ever use it?
  • Under what conditions?
  • Why talk about it?

4
Punishment is Controversial
  • Many states have outlawed the use of some
    punishers (e.g., contingent electric shock)
  • Some advocates claim that reinforcement-based
    procedures are sufficient to reduce all problem
    behavior (e.g., DRO, DRA)
  • Others disagree
  • Even if we are able to eliminate the
    clinical/educational need for punishment,
    research on punishment is still warranted
  • Punishment contingencies that are arranged by the
    physical world are impossible to eliminate exs?

5
Punishment.
  • Should only be used if there is a doctoral level
    behavior analyst on staff full time
  • Why?

6
Introduction
  • As a principle of behavior, punishment is not
    about punishing the person.
  • Punishment is a
  • response consequence contingency that
    suppresses the future frequency of similar
    responses.

7
Definitions Nature of Punishment
  • Positive Punishment Type I Punishment
  • Presentation of a stimulus (or an increase in
    the intensity of an already present stimulus)
    immediately following a behavior that results in
    a decrease in the frequency of the behavior.
  • Negative Punishment Type II Punishment
  • The termination of an already present stimulus
    (or a decrease in the intensity of an already
    present stimulus) immediately following a
    behavior that results in a decrease in the future
    frequency of the behavior.

8
Three-term contingencies illustrating positive
and negative punishment of a discriminated
operant
  • A discriminated operant for punishment is the
    product of a conditioning history in which
    responses in the presence of the SDp have been
    punished and similar responses in the absence of
    the SDp have not been punished.
  • A response (R) emitted in the presence of a
    discriminative stimulus (SDp) is followed closely
    in time by a stimulus change (SP) and results in
    a decreased frequency of similar responses in
    the future when the SDp is present.

9
Definitions Nature of Punishment
  • Discriminative Effects of Punishment
  • SDp
  • A stimulus condition in the presence of which a
    response has a lower probability of occurrence
    than it does in its absence as a result of
    response-contingent punishment delivery in the
    presence of the stimulus.

10
Definitions Nature of Punishment
  • Unconditioned Punisher
  • Primary punisher or unlearned punisher
  • E.g.?
  • Conditioned Punisher
  • Secondary punisher or learned punisher
  • E.g.?
  • Verbal Analog Conditioning
  • E.g.,?
  • Generalized Conditioned Punisher
  • E.g.,?

11
Definitions Nature of Punishment
  • - IMPORTANT POINT -
  • Punishers, like reinforcers, are not defined by
    their physical properties, but by their
    functions.
  • What does that mean?

12
Ethical Considerations Regarding the Use of
Punishment
  • Right to Safe and Humane Treatment
  • The first ethical canon and responsibility for
    any human services program is to do no harm.
  • Least Restrictive Alternative
  • Doctrine of the Least Restrictive Alternative
  • The less intrusive procedures should be tried and
    found to be ineffective before more intrusive
    procedures are implemented.
  • Interventions can be viewed as falling along a
    continuum of restrictiveness from least to most.
  • Gast Wolery (1987) suggest that a more
    intrusive but effective procedure should be
    chosen over a less intrusive but ineffective
    procedure

13
Hierarchy of Procedural Alternatives
Least intrusive
  • Level I
  • Reinforcement-Based Strategies
  • Level II
  • Extinction
  • Level III
  • Negative Punishment
  • Level IV
  • Positive Punishment

Most intrusive
14
Ethical Considerations Regarding the Use of
Punishment
  • Right to Effective Treatment
  • Failing to use a punishment procedure that
    research has show to suppress self-destructive
    behavior similar to the clients is unethical
    because it withholds a potentially effective
    treatment and may maintain a dangerous or
    uncomfortable state for the person.
  • Developing and Using a Punishment Policy with
    Procedural Safeguards
  • Follow a written policy statement.
  • Consult local, state, or professional association
    policy statement regarding the use of punishment.

15
BACB Guidelines for Responsible
Conducthttp//www.bacb.com/consum_frame.html
  • 4.02 Reinforcement/Punishment.
  • The behavior analyst recommends reinforcement
    rather than punishment whenever possible. If
    punishment procedures are necessary, the behavior
    analyst always includes reinforcement procedures
    for alternative behavior in the program

16
ABA Statement on the
Right to Effective Behavioral
Treatmentwww.abainternational.org/ABA/statements/
treatment.asp
  • Individuals who receive behavioral treatment have
    a right to
  • 6 - The most effective treatment procedures
    available An individual is entitled to effective
    and scientifically validated treatment in turn,
    the behavior analyst has an obligation to use
    only those procedures demonstrated by research to
    be effective. Decisions on the use of potentially
    restrictive treatment are based on consideration
    of its absolute and relative level of
    restrictiveness, the amount of time required to
    produce a clinically significant outcome, and the
    consequences that would result from delayed
    intervention.

17
Possible Side Effects and Problems with
Punishment
  • Elicitation of undesirable emotional response and
    aggression
  • Punishment, especially positive punishment in the
    form of aversive stimulation, may evoke
    aggressive behavior with respondent and operant
    components.
  • Aggressive behavior following punishment that
    occurs because it has enabled the person to
    escape the aversive stimulation in the past is
    referred to as operant aggression.
  • Escape and Avoidance
  • Natural reactions to aversive stimulation
  • As the intensity of the punisher increases, so
    does the likelihood of escape and avoidance.
  • Can be minimized by providing alternative
    responses that come into contact with
    reinforcement and avoid the punisher.

18
Possible Side Effects and Problems with
Punishment
  • Increased rate of the problem behavior under
    nonpunishment
  • Behavioral Contrast
  • Change in one component of a multiple schedule
    that increases or decreases the rate of
    responding on that component is accompanied by a
    change in the response rate in the opposite
    direction on the other, unaltered component of
    the schedule.

19
Possible Side Effects and Problems with
Punishment
  • Modeling undesirable behavior
  • Punishment tactics may model undesirable
    behaviors.
  • 2 decades of research have found strong
    correlation between young childrens exposure to
    harsh and excessive punishment and antisocial
    behavior and conduct disorders as adolescents and
    adults.
  • (Patterson, 1982 Patterson, Reid, Dishion,
    1992 Sprague Walker, 2000).
  • Not teaching the learner what to do
  • Overusing punishment because of the negative
    reinforcement it provides the punishing agent.
  • Negative Reinforcement of the Punishing Agents
    Behavior
  • Punishment reinforces the punisher.
  • Punishment tends to terminate the punished
    behavior quickly. The punishers behavior tends
    to be negatively reinforced by the immediate
    cessation of the punished behavior.

20
Increasing the Effectiveness of Punishment
  • Begin with a moderately high-intensity stimulus
  • Do not begin with a mild punisher and slowly
    escalate the intensity (habituation might occur)
  • Deliver the event immediately following behavior
  • Deliver the event on an CRF schedule
  • Schedule thinning can occur after the response
    has been reduced

21
  • Reinforce an alternative behavior

Thompson et al. (1999)
22
Examples of Positive Punishment Interventions
  • Reprimands
  • The delivery of verbal reprimands following the
    occurrence of misbehavior is an example of
    attempted positive punishment.
  • Reprimands given repeatedly may lead to the
    subject habituating to the stimulus
  • Response Blocking
  • Physically intervening as soon as the person
    begins to emit the problem behavior to prevent or
    block the completion of the response has been
    show to be effective in reducing the frequency of
    some problem behaviors.
  • Suppressive effects of response blocking may be
    due to punishment or to extinction.
  • Response blocking as a treatment intervention
    must be approached with great care.
  • Side effects such as aggression and resistance to
    the response blocking procedure have occurred in
    some studies.

23
Examples of Positive Punishment Interventions
  • Contingent Exercise
  • An intervention in which a person is required to
    perform a response that is not topographically
    related to the problem behavior.
  • Contingent Electric Stimulation
  • 46 studies have demonstrated that contingent
    electric stimulation can be a safe and highly
    effective method for suppressing chronic and
    life- threatening self-injurious behavior (SIB).
  • Self Injurious Behavior Inhibiting System (SIBIS)
  • One of the most rigorously researched and
    carefully applied procedures for implementing
    punishment by electric stimulation for
    self-inflicted blows to the head or face.

25
Guidelines for Using Punishment Effectively
  • Select Effective and Appropriate Punishers
  • Punishment as part of a behavior change program
    has nothing to do with retribution.
  • Punishment is not about threats.
  • When punishers are threatened and not delivered,
    the child learns that your verbal threats are not
    associated with the actual punishing behavior.
  • Conduct Punisher Assessments
  • Parallel process to a reinforcer assessment
  • Advantages
  • 1. The sooner an effective punisher can be
    identified, the sooner it can be applied to treat
    the problem behavior.
  • 2. Data from punisher assessments might reveal
    the magnitude or intensity of punisher necessary
    for behavioral suppression. Allows practitioner
    to determine the smallest intensity of punisher
    that is still affective.
  • Consider Using Varied Punishers
  • Varying the form of the punishing stimulus
    enhanced the punishing effect.
  • It appears that by presenting a varied format of
    commonly used punishers, inappropriate behaviors
    may further decrease without the use of more
    intrusive punishment procedures.

26
Guidelines for Using Punishment Effectively
  • Use the Least Intensity of Punishment That is
    Effective
  • Ethical guidelines and the doctrine of the least
    restrictive alternative demand that the most
    effective, but least intrusive, form of
    punishment be used initially.
  • Questions to answer when deciding on a form of
    punishment
  • Will this form of punishment suppress the
    behavior?
  • Will this form of punishment be controlled from
    application to application?
  • Punishment is more effective when the stimulus is
    delivered at its optimum level initially than
    when its intensity is gradually increased over
    time.

27
Guidelines for Using Punishment Effectively
  • Deliver the Punishment Immediately
  • Every instance of the inappropriate behavior
    should be punished.
  • Punishment affects most the behavior that
    immediately precedes the onset of punishment.
  • Deliver the Punishment at the Beginning of the
    Response Chain
  • As much as practical, punishment should occur
    early in the behavioral sequence rather than
    later.
  • .
  • Experience the Punishment Personally
  • Practitioners should experience any punisher
    personally before the treatment begins
  • Doing to reminds the practitioner that the
    technique produces physical discomfort.

28
Guidelines for Using Punishment Effectively
  • Punish Each Instance of the Behavior
  • Punishment is most effective when the punisher
    follows each instance of the behavior.
  • Record, Graph and Evaluate Data Daily
  • Data collection in the first session or two of a
    punishment based intervention is especially
    critical.
  • Graphing the frequency of the target behavior
    before, during, and after the presentation of the
    punisher establishes the effectiveness of
    punishment
  • Deliver the Punishment Unemotionally
  • Punishment should be delivered in a
    business-like, matter-of-fact manner.
  • Resist statement such as, I told you so. Now,
    youve gone and done i. and What do you have to
    say for yourself?
  • All you want to do is modify behavior, not make
    people atone for their sins.

29
Guidelines for Using Punishment Effectively
  • Watch for Side Effects of Punishment
  • The suppression of one inappropriate behavior may
    lead to the increased expression of another or
    the complete suppression of all other behaviors.
  • Decreasing episodes of self-injurious behavior
    bay produce increased levels of verbal
    noncompliance
  • Expand observations to include collateral or
    parallel behaviors
  • Provide Response Prompts and Reinforcement for
    Alternative Behavior.
  • Punishment is most effective when the learner can
    make other responses for reinforcement.
  • The more reinforcement the learner obtains by
    emitting appropriate behavior, the less motivate
    he will be to emit the problem behavior.

30
Some Research to Consider
  • Positive punishment is sometimes necessary to
    reduce problem behavior
  • Hagopian et al. (1998) Participants with DD who
    displayed problem behaviors with various
    functions
  • FCT alone was ineffective
  • FCT EXT ineffective for over half of
    participants when they tried to thin the schedule
    of reinforcement
  • FCT punishment produced a 90 or greater
    reduction in problem behavior even when schedule
    was thinned
  • Positive punishment may be less aversive than
    extinction
  • Hanley et al. (2005) allowed individuals to
    choose which intervention they preferred
  • FCT Punishment was preferred to FCT
    Extinction

31
Some Research to Consider
  • Modeled use of LRA and moving through the
    hierarchy
  • Rapp et al. (2001)
  • Treated a girl with pica evaluated
  • Noncontingent Reinforcement (food)
  • Blocking versus Mild reprimand
  • NCR Blocking
  • Aversive tone

32
Rapp et al. (2001)
33
Concluding Perspectives
  • Recognizing Punishment's Natural and Necessary
    Role in Learning
  • Behavior analysts should not dismiss punishment
    as a potentially helpful option
  • Punishment is a natural part of life
  • Whether punishment is socially mediated, planned
    or unplanned, or conducted by sophisticated
    practitioners, Vollmer (1998) believed that a
    science of behavior should study punishment.

34
Concluding Perspectives
  • More Research on Punishment is Needed
  • Many recommendations for punishment are derived
    from basic research conducted more than 40 years
    ago.
  • Interventions Featuring Positive Punishment
    Should be Treated as Default Technologies
  • Iwata (1988) recommended that punishment-based
    intervention involving the contingent application
    of aversive stimulation, such as SIBIS, be
    treated as default technologies.
  • A default technology is one that a practitioner
    turns to when other methods have failed.

Level III Negative Punishment
  • An event is terminated immediately following a
    behavior ? behavioral reduction
  • 2 Types
  • Response cost Loss of actual reinforcers to
    which the individual currently had access
  • e.g., loss of tokens
  • Time-out Loss of access or opportunity to
    receive reinforcers contingent upon problem
    behavior
  • e.g., loss of access to Moms attention and cool
    toys around the house
  • Contraindicated for behaviors maintained by
    escape!

37
Example of Time Out
SD Adult says, Lets 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)
EO Child is participating in classroom buddy
activities, where attention from peers (a
positive reinforcer) is available.
Poking a buddy occurs less often in the future
when the teacher gives a classroom instruction
and peer buddies are available.
38
Time-out Procedures
  • Nonexclusion
  • Planned ignoring
  • Withdrawal of a specific positive reinforcer
  • Contingent observation
  • Time-out ribbon
  • Exclusion
  • Time-out room
  • Partition time-out
  • Hallway time-out

39
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

40
Effective Use of Time Out
  • Define procedures for the duration of time-out
  • Initial duration should be short
  • Longer than 15 minutes ineffective
  • After time out return student to activity he was
    previously engaged in (dont hold a grudge)
  • Define exit criteria
  • If individual is misbehaving when time-out ends,
    it should be continued until inappropriate
    behavior ceases

41
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

42
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 less intrusive procedures first
  • Consider legal and ethical issues

43
Example of Response Cost
SD Adult says, Lets 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
EO Child has 15 minutes of recess on schedule
every morning.
Poking a buddy occurs less often in the future
when the teacher gives a classroom instruction
and recess is available.
44
Methods of Response Cost
  • Direct fine
  • Bonus response cost
  • The use of reinforcers reduce the legal and
    ethical concerns
  • Combined with positive reinforcement
  • The use of reinforcers reduce the legal and
    ethical concerns
  • Group arrangements

45
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

46
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

47
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

48
Response Cost Considerations
  • Increased aggression may occur
  • Ignore emotional outbursts when possible
  • dont use 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

49
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
