An unconditioned stimulus is one which <span>unconditionally, naturally, and automatically elicits or triggers a(n) (unconditioned) response. For example, the smell of food usually triggers hunger.
In contrast, a conditioned stimulus is one which initially does not trigger the same response as the unconditioned stimulus, but because of association, eventually triggers the same response as well. The response to a conditioned stimulus is a conditioned response.
For example, in the famous experiment by Ivan Pavlov, the sound of a bell was paired with the serving of food to dogs. Dogs naturally salivate upon smelling/seeing the food. However, later on, even without the food, when the dogs heard the sound of the bell, they began salivating. The sound of the bell is the conditioned stimulus, while the salivation of the dog in response to the conditioned stimulus, the bell, is called a conditioned response. </span>
