Final answer:
In classical conditioning, a neutral stimulus becomes a conditioned stimulus and elicits a conditioned response through repeated pairing with an unconditioned stimulus.
Step-by-step explanation:
The term that describes when a previously neutral stimulus, through repeated pairing with the unconditioned stimulus, begins to cause the same kind of reflexive response is classical conditioning. In classical conditioning, the neutral stimulus becomes the conditioned stimulus and the reflexive response it elicits becomes the conditioned response.
For example, in Pavlov's experiments with dogs, the neutral stimulus of a bell became associated with the unconditioned stimulus of food. Eventually, the sound of the bell alone could elicit a response of salivation, even without the presence of food.
