The correct answer is True
Step-by-step explanation:
A discriminative stimulus refers to a type of stimulus in classical conditioning in which a specific stimulus (a reward object or situation) is used to create a specific response in a subject (person or animal), in this way by using the specific stimulus (reward) the subject will perform certain actions or have specific behaviors as a response to the stimulus, and the probability of response to the stimulus increases as more reinforcement is done. Thus, discriminative stimulus implies certain behavior is promoted as the subject knows a reward will come after it.
