2What if you could quit smoking lose weight or
save your autistic child, and do it simply,
painlessly, and without great expense? What if
the only price to pay was abandonment of your
belief in your freedom and dignity? B.F.
Skinner Human Behavior
3B.F. Skinner the most influential psychologist
since Freud
- A failed novelist, he wrote a book depicting a
utopian society, Walden Two. From that Skinner
went on to become the best known behaviorist in
psychology. He developed the behavioral
principles that became the blueprints for
Behavior Modification.
4Major characteristics
- Direct focus on observable behavior not viewed
as altering symptoms, since that would imply an
underlying cause - Assessment of the behavior to be altered I.e
target behavior. Focus on behavior not the
underlying personality.
5- Evaluation of the effect of the program emphasis
is on demonstrating empirical support. - Final characteristic, is the concern for
effecting behavior change that is socially
significant. That is to say, a change that
aligns the behavior with normative standards.
6Advantages of Behavior Modification
- Motivates the person to learn
- Techniques for eliminating undesirable behavior
- Doesnt require language skills
- It moves at the individuals own pace
7Misconceptions about Behavior Modification
- Most of the objections and misconceptions stem
from the use of positive reinforcers. Objections
related to the use of averse events such as
punishment, are based on ethical issues
8Reinforcementa definition
- Behaviors that operate on the environment to
provide the person with rewards or reinforcement.
Thus, any kind of behavior can be defined as
operant in this sense.
9Reinforcement always increases the frequency of a
behavior
- PositiveWhen an event or object is presented as
a consequence of the persons behavior.
- Negative When an event or object is removed or
avoided as a consequence of the persons behavior.
10- Reinforcement is the single most important
principle of behavior modification. - Reinforcers are what behavior modifiers try to
manipulate in the environment to change a
persons behavior. - Just about anything can serve as a reinforcer
11Categories of reinforcers
- Tangible material objects that have personal
value. For example, food, clothes toys, music
CDs, books, etc..
12- Social reinforcers consist of attention, praise,
approval and acknowledgement from other people.
Can be given verbally, Great Job! or
non-verbally, a smile.
13Advantages of social reinforcers
- Easy to administer
- Limitless supply to give
- Can be delivered immediately
- Natural reinforcers, receive as a regular part of
their everyday lives - Dont get satiated!
14- Token reinforcers symbolic items that have value
because of what they can be exchanged for
15- Reinforcing activities Engaging in activities
that the person finds rewarding. For example,
listening to music, shopping, watching TV, etc.
16Premack Principle
- Higher probability behaviors whether they are
considered enjoyable or not can serve as
reinforcers for lower-probability behaviors.
Often referred to as Grandmas Rule
17Types of Reinforcement/Punishment
Present Stimulus
Remove Stimulus
18Factors determining the strength of the
reinforcer
- The item being used person must like it a lot
- How quickly it is given Law of Contiguity use
a bridging signal if needed - Size of reinforcer dont satiate!
- How long since they last received the reinforcer
19The concept of contingency
- This is defined as the thing the person has to do
to get the reinforcer. That is to say, what the
rule is what one has to do to get what they
want! - Therefore, to use reinforcement to strengthen
behavior, the reinforcement must be contingent
upon performance.
20Identifying Reinforcers
- Reinforcement Event Menu List choices for the
person to pick from. This allows the person to
be part of the development of the program as well
as assuring the right reinforcer. - Questioning Asking the client about potential
reinforcers is the easiest and most frequently
used procedure. - Observation Observe client in natural setting.
21Administering Reinforcers
- Sources of Reinforcers
- Reinforcing agents Other people
- provide the reinforcement.
- Self-reinforcement Client reinforces
their own behavior. - This is an area where Skinner
- believed that humans failed.
22Reinforcement Schedules
- A schedule of reinforcement is a rule that
specifies which occurrences of a given behavior,
if any, will be reinforced.
23Types of reinforcement schedules
Continuous
Intermittent
Interval
Ratio
Variable Interval
Fixed Interval
Fixed Ratio
Variable Ratio
24Two Basic Schedules
- Continuous Each occurrence of a response is
reinforced. Start with this when attempting to
add a new behavior to the persons repertoire.
- Intermittent By contrast, each occurrence of the
behavior is not reinforced. Rather, responses
are occasionally or intermittently reinforced.
25Interval Schedules
- Fixed A response is reinforced only after an
interval of time has passed. Often coupled with a
limited hold. For example, nightly news program
- Variable Each time interval is of a different
length. That is, each interval varies around an
average time. For example, your mailman.
26Ratio Schedules
- Fixed Delivered after a fixed number of
responses. Piece work in a factory would be an
example.
- VariableNumber of responses for required for
reinforcement varies each time, around an average
number. A slot machine would illustrate this
point.
27Guidelines for administering reinforcers
- Reinforcers should be contingent on the behavior
- Reinforcers should be delivered immediately after
the behavior occurs - Make client aware as to why they are getting the
reinforcer - Continuous reinforcement first, then intermittent
- Reinforcers should be reinforcing
- Natural reinforcers should be emphasized
- Reinforcers should be given consistently
28Initiating Behaviors Prompting and Shaping
- Prompting Provides the client with cues that
remind or instruct them to perform a behavior.
Can be verbal, environmental, physical, or
behavioral.
- Shaping a procedure in which the components of a
target behavior are reinforced rather than the
complete target behavior.
29Nothing more than bribery!
- This is a frequent concern voiced by many
individuals, especially when using tangibles.
Bribes are given before the behavior is
performed, reinforcers are given after. Bribes
encourage people to do something illegal or
dishonest. Reinforcement is used to reward
people for socially appropriate behavior.
30Behavior modification is coercive
- This objection is often aimed at the means
employed to modify the behavior. - That the person may be compelled to perform a
behavior against their wishes. This refers to
informed consent rather than techniques used. - Finally, that influencing behaviors of other
should be avoided, however, benign.
31Human Rights Review Board
- This board must approve any behavioral program,
research project, etc. before it can be
implemented. Ensures that client is not put in
danger physically, psychologically, financially,
or academically.
32Available precautions to ensure that the
individuals rights are not violated
- Have the individual participate in the
development of the program - Dont make demands that the person cant meet
- Allow for the person to leave the program when
they wish - Reliance on positive reinforcement rather than on
punishment
33All things considered
- Reinforcement therapy has been proven to be
effective in the acquisition of many target
behaviors for a wide variety of clients if used
consistently.
