Unconditioned Stimulus (UCS)
Unconditioned Stimulus (UCS)
A stimulus that naturally and automatically triggers a response without any prior learning; in Pavlov's experiment, it was the dog food.
Conditioned Stimulus
Conditioned Stimulus
A previously neutral stimulus that, after becoming associated with the unconditioned stimulus, triggers a conditioned response.

Study Notes
Classical Conditioning Overview
- Classical conditioning involves pairing a neutral stimulus with an unconditioned stimulus to elicit a response.
- Key components include:
- Unconditioned Stimulus (UCS): naturally triggers a response (e.g., dog food).
- Unconditioned Response (UCR): natural reaction to UCS (e.g., salivating).
- Conditioned Stimulus (CS): previously neutral stimulus that gains significance through association (e.g., buzzer).
- Conditioned Response (CR): learned response to the CS that resembles the UCR (e.g., salivating at sound).
Pavlov's Experiment
- In Ivan Pavlov's experiment, dog food (UCS) causes salivation (UCR).
- A neutral sound (e.g., buzzer) is paired with dog food.
- After several pairings, the buzzer becomes a CS, and the dog salivates (CR) merely at the sound.
Example 1: Nursing Mother
- A nursing mother's response to her baby's cries involves classical conditioning:
- UCS: baby sucking leads to milk flow (UCR).
- After repeated instances, the sound of a baby’s cry (CS) results in milk flowing (CR).
Example 2: Dentist Drill
- The sound of a dentist's drill illustrates the development of anxiety through classical conditioning:
- UCS: drilling causes tension (UCR).
- The sound of the drill (CS) eventually triggers anxiety (CR) before the actual drilling occurs.
