Classical conditioning is a type of learning in which an organism learns to transfer a natural response to a stimulus, to another initially neutral stimulus, which then becomes conditioned. This process occurs through the association between the two stimuli (unconditioned and neutral).
For classical conditioning to be generated, the neutral stimulus must be presented first and a few seconds later the unconditioned stimulus (the process must be repeated several times), so that there can be an association.
Another concept is reinforcement, which means pairing followed by conditioned and unconditioned stimuli, which, if not done, tends to decrease conditioned responses and may lead to extinction, that is, until they disappear.
