Detailed explanation-1: -Have you heard of Pavlov’s dogs? That’s the experiment conducted by Russian physiologist Ivan Pavlov wherein his dogs started to salivate when he rang a bell. This is the best-known example of classical conditioning, when a neutral stimulus is paired with a conditioned response.

Detailed explanation-2: -To test his theory, Pavlov set up an experiment in which he rang a bell shortly before presenting food to the dogs. At first, the dogs elicited no response to the bells. However, eventually, the dogs began to salivate at the sound of the bell alone.

Detailed explanation-3: -In classical conditioning, an unconditioned response is an unlearned response that occurs naturally in reaction to the unconditioned stimulus. 1 For example, if the smell of food is the unconditioned stimulus, the feeling of hunger in response to the smell of food is the unconditioned response.
