  1. Behavior modification 6th Class Shaping, chaining

  2. Techniques for increasing frequency of behavior • Shaping • Chaining • Prompting

  3. Cat and toilet • http://www.youtube.com/watch?v=I1edDfzluXE

  4. Experiment How would you train the cat to use your toilet?

  5. Shaping • Reinforcement of successive approximation of a target behavior. • We look for any behavior that resembles the desired behavior or takes the person closer to it.

  6. Experiment Shaping Hot and cold

  7. Application • Trainingofanimals • Feedback whenlearningnewskills(exercise – somebodyshowssomethingandpeopleproposeshaping feedback) • Management ofpeople(countinghoursfortasks - f, slowpresentations - m) • Sport Training(TimothyGallwey – video?)

  8. Performance curve Perfor-mance Long-term average Time

  9. Example: TennisBuzas, Aylon, 1981 Correct execution of tennis skills (%)

  10. Timothy Gallwey – Inner game • Performace = potential – interference • Interference - critics, fear from failure, past experience of failure • Person can overcome the interference by full focus/attention on some variable/aspect of action

  11. Video • http://vimeo.com/6152948

  12. Exercise Shaping Feedback Poi

  13. Chaining • Reinforcement of successive elements of a behavior chain • Behavior chain – sequence of related behaviors, each of which provides the cue for the next and the last produces s reinforcer • E.g.tying shoes, going to school..

  14. Types of chaining • Forward chaining • Backward chaining

  15. Now try reading this antidisestablishmentarianism

  16. Rules for chaining • Define the target behavior • As a chain! – you must know in advance what sequence you will be dealing with • Reinforce successive elements of the chain • Monitor results

  17. Exercise Shaping Feedback Poi 2

  18. Prompting and fading • Prompting • Providing antecedents that evoke a target behavior • Fading • Gradually reducing the strength of a prompt

  19. Types of prompting • Verbal • Physical • Gestural • Modeling • Environmental

  20. Rules for prompting and fading • Define the target behavior • Identify the suitable prompts • Prompt reinforce and fade • Monitor results

  21. Discussion [The end of the today's class]
