  1. Chapter 8 – Powell, et al. Extinction and Stimulus Control

  2. Extinction I.Extinction A. Process B. Procedure C. Side effects 1.Extinction burst 2.Increased variability 3.Emotional behavior 4.Agression 5.Resurgence 6.Depression

  3. Extinction D.Resistance to extinction by: 1.Partial reinforcement (extinction) effect 2.Longer history of reinforcement 3.Larger magnitude of reinforcer 4.Higher deprivation 5.Previous experience with extinction 6.No discriminative stimulus for extinction (SΔ)

  4. Extinction E.Spontaneous recovery F.Differential reinforcement of other behavior (DRO) – break the contingency

  5. Discriminated Operants: Stimulus Control II Discrimination learning A. Discriminative stimulus - SD B. Extinction stimulus - S C. Discrimination index D. Transfer of training 1.Learning sets 2.Reversals

  6. Discriminated Operants: Stimulus Control III Stimulus control A. Attention B.Generalization C.Discrimination D. Generalization gradients 1. Flat (no attention to dimension) 2. Peaked (attention to dimension) a. jnd

  7. Discriminated Operants: Stimulus Control II Stimulus control (continued) 3. Post-discrimination generalization gradient (along same dimension) a. Peak shift 1) theoretical excitatory gradient 2) theoretical inhibitory gradient 4. Inhibitory stimulus control E. Errorless learning (fading)

  8. Discriminated Operants: Stimulus Control F.Behavioral contrast with multiple schedules 1.Positive behavioral contrast 2.Negative behavioral contrast G.Matching to sample H.Delayed matching to sample I.Arbitrary matching to sample J.Stimulus equivalence

  9. So, what’s my name?

  10. The End
