Chapter 16 – Antecedent Control Procedures
Antecedent control procedures: antecedent stimuli are manipulated to evoke desirable
behaviours, so that they can be differentially reinforced, & to decrease undesirable
behaviours that interfere with the desirable behaviours
oInvolves manipulating some aspect of the physical or social environment to evoke a
desired response, or to make a competing undesirable behaviour less likely
Desirable behaviours may not occur often when the discriminative stimuli (SD) are not
present in the persons environment
Ex – the SD for eating healthy foods is the presence of healthy foods in the kitchen, but if
they are not present, the person will be less likely to eat such foods
oCal bought healthy foods + kept them in his kitchen
oHe also presented cues for the appropriate behaviour – he arranged for stimulus or
response prompts to evoke the desirable behaviour
Made a list of healthy foods to buy when he went shopping (stimulus cue)
Asked his roommate to remind him to eat healthy (response prompt)
His food graph was a reminder (stimulus prompt) to eat right
By presenting the SD or cues for the behavior, you are arranging the right conditions for
the behavior to occur
You arrange the SD or cues for behavior by changing some aspect of the physical or
social environment
Arranging Establishing Operations for the Desirable Behaviors
Establishing operation: an environmental event or biological condition that changes the
value of a stimulus as a reinforcer

oWhen an establishing operation is present, the behavior that results in that
stimulus is evoked (more likely to occur)
oEx – Running 5 miles + sweating is an establishing operation that makes water
more reinforcing, thus strengthens the behavior of getting + drinking water
oIf you can increase the reinforcing value of the consequence, you make it more
likely that the behavior will occur
oEx – Cal bought a health food cookbook – he was making it more likely that he
would cook that tasted good – increasing the reinforcing value
Undesirable behavior can be made less likely to occur by arranging an establishing
operation for a desirable competing behavior
Decreasing Response Effort for the Desirable Behavior
Arrange for antecedent conditions, where less effort is required to engage in the behaviour
Behaviours that take less response efforts are more likely to occur
How did Cal decrease response effort to make it more likely that he would eat healthy?
oBy keeping healthy foods available in the house + getting rid of the junk food
oBy making a healthy lunch + taking it to work
oWould take more response effort to go a restaurant
The different ways to use antecedent control to make it more likely that desirable
behaviour will occur include:
1. Presenting the SD or arrange for cues
2. Arrange an establishing operation
3. Manipulate antecedent conditions that decreases the response effort of undesirable
behaviour
Can be used individually or in combination

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!
