  • 1. BEHAVIOURIST APPROACH TO ABNORMAL BEHAVIOUR<br />
  • 2. Objectives<br />To outline the difference between operant and classical conditioning<br />To understand how abnormal behaviour can be learnt<br />To apply the theory to a real life situation<br />
  • 3. The Behavioural Approach<br />All behaviour is LEARNT/LEARNED<br />List 5 things that you have learnt how to do in your life.<br />
  • 4. What is conditioning?<br />
  • 5. Classical Conditioning<br /><ul><li>Learning through association
  • 6. First proposed by Pavlov, who got dogs to salivate to the sound of a bell.
  • 7. The dogs learnt to associate the bell with their food and would salivate when the bell rang as they expected food to come.</li></li></ul><li>Classical Conditioning<br /> US  UR (Food  Saliva)<br /> CS + US  UR (Bell + Food  Saliva)<br /> CS  CR (Bell  Saliva)<br />
  • 8. Classical Conditioning<br />An unconditioned stimulus will produce an unconditioned response (US  UR)<br />A conditioned stimulus is paired with the unconditioned stimulus and this produces the unconditioned response (CS + US  UR)<br />Eventually the conditioned stimulus alone will produce the desired response, which is now called the conditioned response (CS  CR)<br />
  • 9. Classical Conditioning<br /> US UR<br />CS + US  UR<br />CS  CR<br />Explain how a child could develop a phobia through Classical Conditioning<br />
  • 10. Operant Conditioning<br />Other way to learn behaviours<br />Learning through the consequences of behaviour.<br />Positive/negative reinforcement & Punishment<br />
  • 11. Operant Conditioning<br />B. F. Skinner – rats/pigeons in boxes.<br />Behaviour can be learnt through a series of rewards or punishments<br />E.g. Skinner taught pigeons to play ping pong...<br />
  • 12. Operant Conditioning<br />Positive reinforcement<br />Adding something to the environment to encourage desired behaviour<br />Negative reinforcement<br />Taking something away from the environment to encourage desired behaviour<br />Punishment<br />
  • 13. Speeding<br />Positive Reinforcement?<br />Negative Reinforcement?<br />Punishment?<br />
  • 14. Operant Conditioning<br />Can you think of a way a person might learn abnormal behaviour through operant conditioning?<br />Anorexia<br />OCD<br />Schizophrenia<br />Anxiety disorders<br />Depression<br />
  • 15. Behaviourism in practice...<br />Dear Yr12,<br /> For as long as I can remember I have been afraid of spiders. I can’t be in the same room as a spider and get in quite a state if I see one. I have noticed my daughter has begun to react in a similar way to spiders, she is screaming and crying when she sees one. Why does she copy my behaviour?<br /> Please explain<br /> Susan<br />
  • 16. Behaviourism in practice...<br />Dear Yr12,<br />I am having some problems with my son. He has been banging his head on the floor when he gets stressed. Can you suggest a way I could help him to stop?<br /> Many Thanks<br /> Patrick<br />
