Extinction ( eliminating the reinforcing consequence for a behavior results in a decrease
in the frequency of the behavior) to eliminate a problem behavior because it is no longer
reinforced and therefore will decrease in frequency
You first have identify the reinforce that maintain the problem behavior and then
eliminate it
Should be the f irst approach to be considered for treating problem behaviors
You cant assume tha t a particular reinforce is maintaining a problem behavior. The same
problem behavior exhibited by different people may be maint ained by different
reinforcers
Problem behaviors may be maintained by positive reinforcement when the behavior
results in the presentation of a stimulus event or negative reinforcement when the
behavior results in escape from some stimulus event
When considering the use of extinction to decrease a problem behavior you must
determine that the change agent (a person involved in the problem behavior situation) can
control the reinforcer that maintains the problem Can only be implemented if the change
agent can prevent the reinforcing consequence each time the problem behavior occurs
Important to consider if the use of extinction would result in harm to the person itself or
other people in the immediate environment
Before you use extinction you must anticipate the extinction burst and be certain that the
change agents can tolerate the escalation in the behavior
Consistency must be maintained: the reinforcer must never follow the problem behavior.
Lack of consistency is a common reason for the failure of extinction procedures.
If the problem behavior is reinforced on a continuous schedule extinction is often much
more rapid.If the behavior is maintained by an intermittent reinforcement schedule, the
behavior is likely to decrease more gradually during extinction Therefore, when a
problem behavior is reinforced on an intermittent schedule it might be beneficial to
implement a continuous schedule for a brief period just before extinction. The effect
of extinction would then be more rapid
Extinction should be used in conjunction with a reinforcement procedure to increase an
alternative behavior to replace the problem behavior. The reinforcement procedure will

OneClass has been such a huge help in my studies at UofT especially since I am a transfer student. OneClass is the study buddy I never had before and definitely gives me the extra push to get from a B to an A!
