A type of learning in which a stimulus acquires the capacity to evoke a response that was originally evoked by another stimulus is known as classical conditioning.
In classical conditioning, a stimulus gains the ability to elicit a response that was first elicited by another stimulus. Almost by accident, Pavlov made this type of learning discovery while studying the canine digestive system.
He had surgically inserted a tube into a dog's salivary gland, which was used to collect the saliva the dog made after being given food powder to chew on. Before they were given food, several of Pavlov's dogs started to salivate.
