Lesson 7 applications of classical conditioning

  1. 1. VCE Psychology Units 3 & 4Lesson 7: Applications of classical conditioning
  2. 2. From last lesson………….Outline the following for Pavlov’s experiments•Unconditioned Stimulus -•Unconditioned Response -•Conditioned Stimulus -•Conditioned Response -•Neutral stimulus -
  3. 3. Answer•Unconditioned Stimulus – Meat Powder•Unconditioned Response - Salivation•Conditioned Stimulus - Bell•Conditioned Response - Salivation•Neutral stimulus - Bell
  4. 4. What is classical conditioning?Classical conditioning Who first described classicalrefers to a type of conditioning while conductinglearning that occurs through research into the digestivethe repeated association of system of dogs?two (or more) differentstimuli.Learning is only said tohave occurred when aparticular stimulusconsistently produces aresponse that it did notpreviously produce.
  5. 5. Applications of classical conditioningClassical conditioning has a number of ‘real-life’ applications. Applications of classical conditioning Graduated Aversion Flooding exposure therapy Treatment method Presenting successive The inhibition or for fears/phobias by approximations of the discouragement of extinguishing the CS until the CS undesirable behaviour CR. itself does not by pairing it with an produce the CR. aversive stimulus.
  6. 6. Graduated exposureGraduated exposure involves It has been successfully usedgradually presenting to eliminate a range ofsuccessive approximations of problems involving fearthe CS until the CS itself and anxiety responses suchdoes not produce the CR. as a fear of flying.It is a process that involvesthe extinction of theassociation between the CSand the CR.It is also known as‘systematic desensitisation’.

  7. 7. Graduated exposureThe steps in graduatedexposure are:• teach the person a relaxation strategy• break down the CS into a sequence arranged from least to most anxiety- producing (a fear hierarchy)• gradually begin to extinguish the CR by pairing items in the hierarchy with relaxation by working upward through items in the hierarchy.
  8. 8. Graduated exposureGraduated exposure can be doneby using:• visual imagery (imaginal exposure)• real-life exposure (in vivo exposure)• virtual reality technology.The best results appear to occurusing in vivo graduated exposures. Source: Macmillan Australia

  14. 14. FloodingFlooding involves bringingthe client into direct contactwith the CS and keepingthem in contact with it untilthe CR is extinguished.The principle underlying thistechnique is that anxietywill be experienced at avery high level and thengradually diminish, therebyenabling the client toexperience the CS in theabsence of the CR.

  16. 16. Quick quiz• Question 1: What does graduated exposure involve?• Answer: Gradually presenting successive approximations of the CS until the CS itself does not produce the CR.• Question 2: The best results when using graduated exposure appear to occur via imaginal exposure. True or false?• Answer: False, best results are using in vivo graduated exposures.• Question 3: What does aversion therapy involve?• Answer: Inhibiting or discouraging an undesirable behaviour by pairing it with an aversive stimulus.• Question 4: The idea behind aversion therapy is that the undesired behaviour becomes the CS. True or false?• Answer: True.• Question 5: Name one behaviour that can be treated by aversion therapy.• Answer: Alcoholism, drug dependence, nail biting, gambling, sexual behaviours.• Question 6: Flooding involves bringing the client into direct contact with the CS in order to strengthen the association with the CR. True or false?• Answer: False, it is designed to extinguish the association with the CR.• Question 7: What is the underlying principle of flooding?• Answer: That anxiety will be experienced at a very high level and then gradually diminish.
