Answer:
Classical conditioning.
Explanation:
Classical conditioning introduced by Russian physiologist Ivan Pavlov, (26 September 1849 – 27 February 1936) in 1897, comprises a learning procedure that conditions a certain response from a subject. Two types of stimuli are used in the classical conditioning: and meaningful (potent) and neutral.
For example, door bell (neutral stimulus) that Mike hears already makes him to drool because, he knows that it is a pizza delivery guy is ringing the bell and soon Mike will eat his favourite pizza. Earlier, only the appearance and smell of pizza (meaningful stimulus) made Mike to drool. This situation can be recreated in the experimental environment to prove classical conditioning.
