Those antidepressant drugs that are in wide clinical use decrease response rate and increase reinforcement rate when administered to rats performing on a differential-reinforcement-of-low-rate 72-s (DRL 72-s) schedule. Drugs that are not antidepressants do not have this effect. In this experiment, t
Three rats, deprived of water, were given separate injections of methylphenidate and pentobarbital after each had received extensive training on a DRL schedule of reinforcement, modified by the inclusion of a limited-hold. Mcthylphenidate (2.5, 5.0, and 10.0 mg/kg) increased response rates at each o
Rats were trained to discriminate phenobarbital (50 mg/kg) vs saline in a two-bar, thirst-motivated operant drug discrimination task. Presses on bar 1 were reinforced when the rat was drugged and presses on bar 2 when not drugged. Several shaping procedures and schedules of reinforcement were compar
