324 09 avoidance

  1. 1. Human Learning Topic 9: AvoidanceCEDP503 Ryan Sain, Ph.D. 1 3/30/2012
  2. 2. Discriminated Avoidance A warning signal is given A response prevents or removes the stimulus Escape trials  Organism makes response to ‘remove’ stimulus  Happens early in training Avoidance trials  Organism makes response to avoid stimulus
  3. 3. Two process theory What do you ‘get’ in avoidance?  Actually nothing  ‘nothing’ cant cause something Two process theory  Explains most of avoidance behavior  Is the standard  Is not perfect
  4. 4. More two-process Classical conditioning  CS paired with US  fear  motivation Operant conditioning  Reduction of fear is a negative reinforcer  Terminating the CS  reducing fear
  5. 5. What is learned? Escape from conditioned fear  This maintains the behavior Prevention of shock  Is the by-product or outcome of the behavior  This does not control the response
  6. 6. Acquired drive Experimental paradigm Separate CC and OC components Produce conditioned fear  CS  US Expose CS and permit termination of it  Organisms learn to make the response
  7. 7. Extinction of avoidance Avoiding a stimulus  Breaking the CS-US connection of fear  But the response persists dramatically How to extinguish?  Flooding  Present the CS without the US  Do not allow the avoidance response  Response blocking  Prevent response that terminates the CS  No CS US pairings  Failure to make the avoidance response  no shock
  8. 8. Free operant avoidance No warning signal Two process theory does not explain this Organisms still learn to make the response Humans  CO2 administrations for 20 seconds  Pull a plunger prevents this  No instructions provided
