Answer to Question 1

In physical dependence, when a person stops taking the drug a set of physiological symptoms will appear as the drug level in the system drops (withdrawal). Symptoms disappear when the drug is taken again. In psychological dependence, when a person takes a drug (behavioral act), they receive a consequence such as a feeling of euphoria, perhaps. This consequence increases the likelihood that the drug will be taken again. Thus, the behavior is being reinforced by the consequence.
