Extinction

The removal of a reinforcer from a previously reinforced behavior which causes the behavior to decrease.

Example: Extinction ABC BehaviorWithholdBehavior Occurs ReinforcementStops

Example: Extinction ABC Turn on No light Stop turning light switch on light switch

Extinction Burst – Temporary increase in responding as a result of the introduction of extinction. – Sometimes a change in topography may occur.

Example: Extinction Burst ABC Turn onNo Light Turn on/off light switch Repeatedly and then Stop or do a new behavior

Extinction Examples Vending Machine Head banging * What does this suggest about ignoring behavior?

Your Turn Come up with an example of how Reinforcement has been withheld from your behavior and what followed. Share with your peers.

Spontaneous Recovery Temporary recovery of an extinguished behavior that follows the initial treatment session. – An extinguished Behavior will come back, but usually less intense and shorter duration. √ Must wait out the storms

Factors that influence the Effectiveness of Extinction Controlling reinforcers – e.g. Accidental reinforcement The Setting in which Extinction is Carried out – e.g. Tantrums in Wal*Mart Rules – E.g. Make use of our capabilities The schedule of reinforcement – The thinner the schedule the more resistance to extinction Extinction Burst e.g. Tantrums
