Classical Conditioning Study Notes

BEHAVIORISM AND CLASSICAL CONDITIONING

• Focus on examining responses to stimuli through behaviorism.

• Recognizes importance despite perceived limitations.

WHAT IS BEHAVIORISM?

• Studies observable cause-and-effect relationships between stimuli and behavior.

• Assumes behavior results largely from stimulus-response relationships.

• Acknowledges that examining observable behavior aids scientific exploration.

RADICAL BEHAVIORISM

• Concept that all behavior can be explained as stimulus-response interactions.

• Introduced by B.F. Skinner; influenced by John B. Watson.

• Emphasizes the ability to train individuals regardless of their inherent traits or backgrounds.

TWO MAIN FORMS OF LEARNING

• Classical Conditioning: Learning connections between stimuli (involuntary).

• Operant Conditioning: Learning consequences of actions in environments (voluntary).

IVAN PAVLOV AND CLASSICAL CONDITIONING

• First behaviorist, discovered classical conditioning through studies on dog digestion.

CLASSICAL CONDITIONING TERMS

• Unconditional Reflex: Unconditional Stimulus (UCS) elicits Unconditional Response (UCR).

• Conditional Reflex: Conditional Stimulus (CS) elicits Conditional Response (CR).

• Neutral Stimulus (NS): Becomes a CS only after being paired with UCS.

CLASSICAL CONDITIONING FORMULA

• Before training:

  • UCS (food) → UCR (salivation)

  • NS (tone) → No response

• During training:

  • NS (tone) + UCS (food)

• After training:

  • UCS (food) → CS (tone)

  • UCR (salivation) → CR (salivation)

LINKING TO REAL LIFE

• Stressors can act as UCS leading to stress responses (UCR).

• Environmental cues can become conditioned stimuli leading to conditioned responses.

NUANCES TO LEARNING

• Learning curves, forgetting curves, extinction, spontaneous recovery.

• Response patterns influenced by pairing (CS+US) and timing (CS alone).

FORMS OF CLASSICAL CONDITIONING

• Trace Conditioning: NS precedes UCS.

• Delayed Conditioning: NS sustained while UCS presented.

• Simultaneous Conditioning: NS and UCS presented simultaneously.

• Backward Conditioning: UCS precedes NS (ineffective).

OTHER RELATED DISCOVERIES

• Conditioning influenced by familiarity of the NS and species-specific tendencies.

• Generalization: Responding to similar stimuli.

• Discrimination: Differentiating between similar stimuli.

INSIGHT ON LEARNING

• Classical conditioning reveals pairing of stimuli but not how to act in the environment.

• Future classes will explore behaviorism through operant conditioning.
