    Behavior controlled by various schedules of reinforcement is useful for characterizing drugs as well as for analyzing the mechanisms of action of their effects on behavior. Conditioned avoidance techniques have been useful for studying neuroleptics and for predicting their clinical antipsychotic acitivity; the possible involvement of dopaminergic mechanisms in the effect of neurolpetics on avoidance behavior is discussed. Tricyclic antidepressant agents have been studied in assays involving interactions with other agents, such as cocaine, amphetamine and tetrabenazine. One type of operant behavior, Sidman avoidance, has been used as particularly sensitive assay for such drug interactions. Another schedule, in which "observing" responses in pigeons are measured. seems to provide a method for studying antidepressants without involving drug interaction phenomena. For tricyclic compounds, facilitation of observing responses and weak potency of conditioned avoidance inhibition constitute a pharmacological profile that seems to have some predictive value for clinical imipramine-like antidepressant activity. "Conflict (punishment) schedules have been useful for predicting antianxiety activity in man. Although the degree of anticonflict effect observed is consistent with Dew's rate dependency hypothesis, this principle does not fully account for the observed drug effects. In the conflict model, the actions of benzodiazepines differ in drug-naive versus drug-experienced animals. Experiments with parachlorophenylalnine have not yet provided clear support for the postulated role of serotonin in related phenomena.
