In psychology, the term habituation refers to a part of the learning process where the response to a particular stimulus decreases because the stimulus is presented many times. In other words, the person "gets used" to this stimulus and stops reacting the way it used to in the first place.
In this example, Andrew was startled the first time he heard the ring of the telephone, however, with each subsequent ring he seemed to become less reactive. We can see that at first, Andrew reacted in a startled way, however, as this stimulus (the ringing) has been repeating, he is getting used to it and he becomes less reactive. Therefore, this best illustrates the process of habituation.
