Answer:
Classical conditioning.
Explanation:
<em>Classical conditioning</em> introduced by Russian physiologist Ivan Pavlov, (26 September 1849 – 27 February 1936) in 1897, comprises <em>a </em><u>learning procedure that conditions a certain response from a subject.</u> Two types of stimuli are used in the classical conditioning: and <em>meaningful </em>(potent) and <em>neutral</em>.
For example, door bell <em>(neutral stimulus)</em> 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 <em>(meaningful stimulus)</em> made Mike to drool. <u>This situation can be recreated in the experimental environment to prove classical conditioning.</u>
