Quizplus · Accepted Answer

Research has shown that dopamine-blocking drugs decrease the reinforcing value of cocaine, which suggests that dopamine is involved in the rewarding effects of drugs of abuse. Option A is incorrect because dopamine-blocking drugs decrease the pleasurable effects of food, leading to decreased intake. Option B is incorrect because dopamine-blocking drugs decrease the pleasurable effects of electrical stimulation of the nucleus accumbens. Option D is incorrect because blocking dopamine receptors does not prevent all forms of learning, but it can impair certain types of learning that rely on dopamine signaling in the brain.
