From the description given in the question it is clear that Maurice’s understanding of the association between his father’s keys opening the lock and his father’s appearance is a form of classical conditioning. Classical conditioning is <em>a learning process that occurred when an organism associates a neutral stimulus with an unconditioned response, due to the presence of an unconditioned stimulus. </em>
It can be said that the sound of the key is the neutral stimulus, and the unconditioned stimulus is Maurice’s father appearance, while the unconditioned response is his happiness at seeing his father. Because Maurice has associated the sound of the key with his father’s appearance, his behavior changed even when the neutral stimulus appears, because he anticipates that the unconditioned response would appear afterwards.
