Antecedent Control Procedures


Antecedent control procedures l.jpg
Antecedent Control Procedures

  • Based on functional assessment information

  • One of three functional, nonaversive interventions

  • Involves altering the environment in advance of the target behavior

  • Addresses antecedents rather than consequences of operant behavior

  • Addresses consequences indirectly through manipulation of establishing operations

  • Increases the probability of the desirable target behavior and decreases the probability of undesirable alternative behavior

  • Also called stimulus control procedures or situational inducement


Procedures to increase the probability of the desirable target behavior l.jpg
Procedures to Increase the Probability of the Desirable Target Behavior

1. Present SD or cues for desirable behavior

2. Present EO for desirable behavior

3. Decrease response effort for desirable behavior


Present s d or cues for desirable behavior l.jpg
Present SD or cues for desirable behavior

  • The desirable behavior is under the stimulus control of the SD

  • When the SD is present, the behavior is more likely

  • Cues serve as prompts or reminders

  • Examples:


Examples presenting s d s or cues l.jpg
Examples: Presenting SDs or cues

  • Seating arrangement to facilitate conversation in a nursing home

  • Reminder to floss on the bathroom mirror

  • Fruit in the fridge

  • Going to the library to study

  • Activity placemats at restaurants


Present eo for desirable behavior l.jpg
Present EO for desirable behavior

  • An EO makes the reinforcer for the desirable behavior more potent

  • An EO increases the probability of the desirable behavior

  • Examples:


Examples presenting eos l.jpg
Examples: Presenting EOs

  • No snacks before meal time

  • Arrange a contact for getting work done

  • No naps to make sleeping more likely at night

  • Pictures of rotten teeth to make flossing more likely

  • Decrease wait time for MR person who has to stand in line at a store


Decrease response effort for desirable behavior l.jpg
Decrease response effort for desirable behavior

  • A behavior is more probable when it requires less response effort than does a concurrent operant

  • Response effort may be decreased through environmental manipulation

  • Examples:


Examples decreasing response effort l.jpg
Examples: Decreasing response effort

  • Recycling box next to desk

  • Healthy foods in easy reach

  • Books in backpack

  • Easy to use car seats

  • Coffee shop on every corner


Procedures to decrease the probability of competing undesirable behavior l.jpg
Procedures to Decrease the Probability of Competing (Undesirable) Behavior

1. Remove SDs or cues for competing behaviors

2. Eliminate EOs for competing behaviors

3. Increase response effort for competing behavior


Remove s d s or cues for competing behaviors l.jpg
Remove SDs or cues for competing behaviors

  • In the absence of the SD, the competing behavior is less likely

  • Examples:


Examples removing s d s or cues l.jpg
Examples: Removing SDs or cues

  • Get junk food out of the house

  • Keep partying friends out of your place at study time

  • Separate fighting kids at the restaurant

  • Don’t drive past McDonalds after school


Eliminate eos for competing behaviors l.jpg
Eliminate EOs for competing behaviors

  • Without an EO, the reinforcer for competing behavior will not be potent

  • Without an EO, the competing behavior is less likely to occur

  • Examples:


Examples removing eos l.jpg
Examples: Removing EOs

  • Curriculum modifications to reduce problem behavior maintained by escape

  • Noncontingent attention, tangibles, or breaks

  • Provide choice of activities

  • Pain relief

  • Mood induction

  • Food shopping only after eating


Increase response effort for competing behavior l.jpg
Increase response effort for competing behavior

  • A behavior that requires more response effort than a concurrent operant is less likely

  • Response effort is increased through environmental manipulation

  • Examples:


Examples increase response effort l.jpg
Examples: Increase response effort

  • No change in pockets/purse for candy machines

  • No junk food in the house

  • Seat aggressive person away from victim

  • Keep trash can away from desk (recycle box on desk)


Using antecedent control procedures l.jpg
Using Antecedent Control Procedures

  • Assess antecedents and consequences for desirable behavior and competing behavior

  • Assess response effort for desirable and competing behaviors

  • Determine which relevant SDs and EOs you can manipulate

  • Determine whether you can manipulate response effort for desirable or competing behaviors


Factors that influence the use of antecedent control procedures l.jpg
Factors that influence the use of antecedent control procedures

  • Have you identified the relevant antecedents?

  • Can these antecedents be altered?

  • How acceptable will it be to alter these antecedents?
