  1. Psychology of LearningEXP4404 Chapter 10: Generalization, Discrimination, and Stimulus Control Dr. Steve

  2. Topics Covered • Generalization • Measurement • Semantic Generalization • Discrimination • Discrimination Training • SD vs. SΔ • Procedures • Stimulus Control • Theories of Generalization and Discrimination • Analysis of Behavior

  3. Generalization • Generalization • Classical Conditioning • Operant Conditioning

  4. Generalization • Generalization is vital to learning and survival and crucial to research • Increase generalization by learning or practicing in a variety of settings

  5. Generalization • Generalization Gradient

  6. Generalization • Primary vs. Secondary Generalization • Primary- • Secondary

  7. Generalization • Semantic Generalization

  8. Generalization • Generalization of behaviors following punishment or extinction • Inhibitory generalization Responses S-

  9. Discrimination • DiscriminationTraining • Training procedure: • Acquisition of response in one situation • Extinction of response in all other situations

  10. Discrimination • Discrimination Training Methods • Successive Discrimination Training • Simultaneous Discrimination Training • Matching to Sample • Oddity Matching

  11. Discrimination • Discrimination Training S+ S- Video example discrimination training to encourage stair use

  12. Discrimination • Errorless Discrimination Training • Differential Outcome Effect

  13. Stimulus Control • Stimulus Control Imprecise Stimulus Control Precise Generalization Discrimination

  14. Stimulus Control • Variables that effect stimulus control (Generalization vs. Discrimination) • Practice • Schedule of Reinforcement • Delay of Reinforcement • Goal of Training • Generalization • Discrimination

  15. Theories of Generalization & Discrimination • Discrimination Training characterized by:

  16. Theories of Generalization & Discrimination Peak Shift Behavioral contrast S-

  17. Theories of Generalization & Discrimination • Pavlov’s Theory • The more closely a neutral stimulus resembles a CS+, • If neutral stimulus resembles CS-,

  18. Theories of Generalization & Discrimination • Spence’s Theory • (excitatory gradient) • (inhibitory gradient) • (algebraic summation) Peak Shift Excitatory Gradient Net Gradient P(Response) Inhibitory Gradient S+ S- 250 500 750 1000 Hz

  19. Theories of Generalization & Discrimination • Lashley-Wade Theory

  20. Theories of Generalization & Discrimination • Kohler’s Relational Theory • Transpositional Effect S+ S- Discrimination Training Learned “lighter than”

  21. Analysis of Behavior • Mental Rotation or Discrimination Training?

  22. Analysis of Behavior • Smoking Relapse

  23. Analysis of Behavior • Experimental Neuroses • Type of learned helplessness • E.g., child who can’t figure out how to please mother (what is considered a properly made bed)
