Quizplus · Accepted Answer

The scenario describes the development of tolerance, which occurs when a person needs increasing doses of a drug to produce the same effect. A is incorrect because stimulus generalization refers to responding to stimuli that are similar but not identical to the original conditioned stimulus. B is incorrect because extinction refers to the reduction or elimination of a conditioned response. C is incorrect because drug stimulus discrimination occurs when a person learns to differentiate between drug-related and non-drug-related stimuli.
