Chapter 14: Applying Extinction
Use of extinction to eliminate a problem behaviour after identify reinforce that
maintain it, eliminate it a behaviour no longer reinforced decrease in frequency &
stops
The Case of Willy
Willy - 54-year old man w/ mild mental retardation recently moved into group
home exhibited problem behaviour of arguing when asked to do training activity
(e.g. cleaning ) functional assessment: Antecedent female staff asking &
Consequences staff provides attention treatment: was training staff not provide
attention when Willy acts out
First provided the instructions for use of extinction & then, model it - then had
another staff role-play asked each staff to rehearse & instructed that his
behaviour might get worse before getting better so be prepared to not reinforce it
In conjunction w/ that instructed the staff to praise when Willy start to engage in
behaviour requested problem behaviour will decrease & co-operative behaviour
will increase
To promote generalization asked ALL STAFF must use extinction (& reinforcing
good behaviour) at ALL TIME in ALL SITUATIONS mean this must continue
when he visits his parents either by not asking to do anything (stimulus control) or
follow extinction procedure as well
His refusal to do task decrease over time once extinction was implemented & only
refused once in while most often, he completed the task
Using Extinction to Decrease Problem Behaviour
Should be one of first approaches to be considered for treating problem behaviour
thus; to decrease a behaviour , an important step is to identify the reinforcing
consequences, and eliminate it Steps involved in extinction:

1.Collecting Data to Assess Treatment Effects
Must collect data on problem behaviour in all relevant settings after treatment to
determine whether: behaviour decreased, generalization occurred & continued data
collection over time to assess the maintenance of behaviour change
oSummary: to document the change in behaviour after the use of the procedure
2.Identifying the Reinforcer for the Problem behaviour through Functional
Assessment
can identify antecedent & consequences of the problem behaviour must identify
specific reinforcer for that behaviour & eliminate it
Same problem behaviour exhibited by different people may be maintained by
different reinforce e.g. aggression for one is reinforced by attention & for
another it is getting toys back from siblings
Same behaviour exhibited by a particular person in different situation might be
maintained by different reinforcers e.g. crying in order to get help vs. crying to
escape doing chores
oBehaviour may serve different functions in different context
3.Eliminating the Reinforcer after each Instance of the Problem behaviour
# of considerations need to addressed for the successful use of extinction:
Have you Identified Reinforcer? failure to eliminate particular stimulus event that
functions as reinforcer for the behaviour = failure to implement extinction correctly
oExtinction procedure may be different depending on the reinforcer that is
maintain that behaviour e.g. Iwata for SIB behaviour from Chapter 13
Can you Eliminate the Reinforcer? Determine whether change agent (e.g. parent) can
control the reinforcer each time the problem behaviour occurs only then
