Title: Classical Conditioning


1
Classical Conditioning
  • Ivan Pavlov

2
Ivan Pavlovs Failure
  • Early 19 hundreds
  • No restrictions on the type of research you could
    do. (PETA, IRB,)
  • Dogs digestive track.
  • Tube inserted into the dogs stomach
  • Given food, then saliva collected in a jar
  • Timed the processing from start to finish.
  • Complete Failure
  • Dogs would salivate all the time.

3
Ivan Pavlovs Background
  • Classically Educated Scientist
  • Philosophy of Aristotle
  • Learn through similarities
  • Learn through differentiation
  • Learn through contiguity
  • One object is associated with another
  • No logical relationship
  • Objects are just PAIRED together.

4
Classical Conditioning
  • Theoretical Model (Static)
  • Stimulus Response
  • Causal relationship between events
  • Cookies baking smell hunger pangs
  • Stimuli
  • Cause of the response
  • Types of Stimulus
  • Unconditioned Stimulus (US)
  • Natural cause of the response
  • Conditioned Stimulus (CS)
  • Unnatural cause of the response
  • Neutral Stimulus (NS)
  • Causes nothing

5
Classical Conditioning
  • Responses
  • Natural reaction to stimulus
  • Characteristics of C.C. responses
  • Involuntary
  • Physiological
  • Reflex
  • Types of Responses
  • Unconditioned Response (UR)
  • Natural reaction to a stimulus
  • Conditioned Response (CR)
  • Unnatural reaction to a stimulus

6
Classical Conditioning
  • Theoretical Model (Dynamic)
  • Stage 1 US UR
  • Meat Saliva
  • Stage 2 US NS UR
  • Meat Bell Saliva
  • Stage 3 CS CR
  • Bell Saliva

7
Classical Conditioning
  • Methods for Associating
  • Repetition
  • Meat Bell, over and over again
  • Profound Experience
  • Usually a trauma
  • Near death experience
  • Our Song

8
Classical Conditioning
  • Features of Classical Conditioning
  • Generalization
  • Stimulus is close enough to CS that it causes a
    CR.
  • Glass clinking causes dogs to salivate
  • Discrimination
  • Stimulus is different enough from CS that it
    doesnt cause a CR.
  • Key chain does not cause dogs to salivate
  • Extinction
  • Continued presentation of the CS without the US
