Question

In Pavlov's experiment, what was the unconditioned stimulus (UCS)?

• A. Bell
• B. Salivation
• C. Food
• D. No Response

Answer 1

Answer:

C. Food

In Ivan Pavlov's classical conditioning experiment, the unconditioned stimulus (UCS) was food. This stimulus naturally and automatically triggered salivation in dogs. Pavlov paired the presentation of food with a neutral stimulus (a bell) to eventually condition the dogs to salivate at the sound of the bell alone.
