3Introduction
- Punishment is
- Poorly understood
- Frequently misapplied
- Controversial
- Will you ever use it?
- Under what conditions?
- Why talk about it?
4Punishment 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?
5Punishment.
- Should only be used if there is a doctoral level
behavior analyst on staff full time - Why?
6Introduction
- 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.
7Definitions 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.
8Three-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.
9Definitions 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.
10Definitions 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.,?
11Definitions Nature of Punishment
- - IMPORTANT POINT -
- Punishers, like reinforcers, are not defined by
their physical properties, but by their
functions. - What does that mean?
12Ethical 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
13Hierarchy of Procedural Alternatives
Least intrusive
- Level I
- Reinforcement-Based Strategies
- Level II
- Extinction
- Level III
- Negative Punishment
- Level IV
- Positive Punishment
Most intrusive
14Ethical 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.
15BACB 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
16ABA 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.
17Possible 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.
18Possible 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.
19Possible 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.
20Increasing 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)
22Examples 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.
23Examples 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.
24Linscheid, Iwata, Ricketts, Williams, Griffin,
1990
25Guidelines 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.
26Guidelines 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.
27Guidelines 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.
28Guidelines 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.
29Guidelines 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.
30Some 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
31Some 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
32Rapp et al. (2001)
33Concluding 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.
34Concluding 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.
35PunishmentBy Stimulus Removal
36 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!
37Example 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.
38Time-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
39Effective 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
40Effective 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
41Effective 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
42Effective 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
43Example 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.
44Methods 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
45Effective 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
46Effective 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
47Effective 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
48Response 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
49Response 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
