10. 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
