Answer: Conditioned stimulus.
Fear conditioning refers to a learning behaviour in which an aversive stimulus is paired with a neutral stimulus, up to the point in which the neutral stimulus elicits the same response as the aversive one, even when not paired together.
Before the experiences, the doctor was a <u>neutral stimulus</u> because his effect did not depend on previous experience. The <u>aversive stimulus</u> was the shots. The pairing of the doctor with the shots repeatedly elicits the <u>conditional response</u>, which is the crying. It also turns the doctor into a <u>conditioned stimulus</u>.
