Classical Conditioning

Classical Conditioning

• Ivan Pavlov

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.

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.

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

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
