Classical conditioning.

Explanation:

Classical conditioning first studied and illustrated by Ivan Pavlov(Russian Psychologist) that arises learning when a conditioned stimulus is combined with an unconditioned stimulus. It exemplifies the learning through association which is an outcome of pairing or linking of two stimuli in order to produce a new learned response in an individual. The given passage reflects this process(classical conditioning) as Juan affiliates the song to his childhood days that results in a warm emotional response from him. Thus, it displays classical conditioning.
