Classical Conditioning Quiz

Classical Conditioning Overview

• Classical conditioning is a learning process where a natural response to one stimulus is triggered by a previously neutral stimulus.
• Key figures include Ivan Pavlov, who unintentionally discovered this phenomenon through experiments with dogs.

Key Concepts

• The classical conditioning formula consists of three main components:
  • Unconditioned Stimulus (UCS) naturally elicits a response (UCR).
  • A Neutral Stimulus (NS) paired with UCS leads to a Conditioned Stimulus (CS) that elicits Conditioned Response (CR).

Terminology

• Unconditioned Stimulus (UCS): Esp: food; naturally causes a specific response.
• Unconditioned Response (UCR): Esp: salivation; an automatic, unlearned reaction to UCS.
• Conditioned Stimulus (CS): A previously neutral stimulus that, after association with UCS, evokes a conditioned response.
• Conditioned Response (CR): The learned reaction to the CS.

Advanced Conditioning

• Higher Order Conditioning: A conditioned stimulus can serve as an unconditioned stimulus for further learning (e.g., a light predicting a tone that signals food).
• Factors affecting conditioning include:
  • Strength: Stimuli must be noticeable to elicit responses.
  • Timing: Optimal pairing of UCS and NS is crucial; NS should precede UCS for best results.
  • Frequency: Repeated pairings solidify associations.

Conditioning Effects and Variations

• Blocking: Previous association with UCS can prevent conditioning to a new stimulus if presented simultaneously.
• Backward Conditioning: NS may appear either before or after the UCS but not both; it’s less effective.
• Taste Aversion: A learned aversion after becoming ill from a specific food.

Notable Studies

• Kamin's Work: Demonstrated blocking where rats did not fear a light if it was only associated with a previously conditioned tone and shock.
• Rescorla's Work: Showed the context can influence response; a tone signaling fear or relaxation based on its pairing with shock.

Extinction and Recovery

• Extinction: Occurs when CS is no longer paired with UCS, leading to the CS reverting to a neutral state (e.g., Baby Albert losing fear of fluffy white objects).
• Spontaneous Recovery: The return of a conditioned response after a period of extinction indicates learned behavior has not been entirely erased.

Generalization and Discrimination

• Generalization: Responding similarly to stimuli that are similar to the CS.
• Discrimination: Distinguishing between different stimuli, responding only to specific CS associated with UCS.

Clinical Applications

• Preparedness: Some behaviors are naturally easier to condition based on an organism's instincts.
• Contrapreparedness: Conditioning is hindered when behaviors conflict with natural instincts.
• Systematic Desensitization: Involves a hierarchy of fearful situations and relaxation techniques to gradually reduce fear.
• Flooding: Clients confront their greatest fears to diminish longstanding fears; facing worst-case scenarios often leads to overcoming fear reactions.
