Types of Learning • Classical Conditioning – Pavlov, Garcia • Operant Conditioning – Skinner, Watson • Observational Learning – Bandura

Defining Learning • A change in knowledge or behavior that results from experience.

Pavlov’s Apparatus • Harness and mouth tube help keep dog in a consistent position

Pavlov’s Apparatus • Harness and mouth tube help keep dog in a consistent position to gather uncontaminated saliva samples

Before Conditioning • Before Stimuli Are Paired – Unconditioned Stimulus (UCS) elicits Unconditioned Response

Before Conditioning • Before Stimuli Are Paired – Unconditioned Stimulus (UCS) elicits Unconditioned Response (UCR) • Meat elicits salivation – Neutral stimulus (NS) elicits no particular response • The bell does not lead to a particular response

During Conditioning • Conditioning: Neutral Stimulus (NS) is paired with the Unconditioned Stimulus (UCS)

During Conditioning • Conditioning: Neutral Stimulus (NS) is paired with the Unconditioned Stimulus (UCS) – Bell rings, then meat powder is delivered – This pairing happens a number of times (trials)

After Conditioning • After several trials, when the bell rings, the dog salivates (NO

After Conditioning • After several trials, when the bell rings, the dog salivates (NO FOOD NEEDED!) – The Bell is now a Conditioned Stimulus (CS) – Salivation is a Conditioned Response (CR)

Classical Conditioning Terms • Acquisition – Formation of a learned response to a stimulus

Classical Conditioning Terms • Acquisition – Formation of a learned response to a stimulus through presentation of an unconditioned stimulus • Extinction – Elimination of a learned response by removal of the unconditioned stimulus • Generalization – When the classically conditioned reaction occurs to other (similar) stimuli

Learning Factors • Number of pairings • Reliability of CS in predicting UCS •

Learning Factors • Number of pairings • Reliability of CS in predicting UCS • Occurrence of CS just before UCS

Timing of CS before UCS
