Rats were reinforced with water on a continuous reinforcement schedule and were also punished with electric shock for every fifth response applied to a silent, isometric, force-sensing manipulandum. Oral doses of chlordiazepoxide (3.0, 9.0, 27.0 mg/kg) increased both conventional rate and force of p
Several studies have recently established that chlorpromazine will affect the acquisition and extinction of a conditioned avoidance response in rats (ADER and CLINK 1957; MILLER et al. 1957;1957a). ADER and CLI~X (1957) used saline, 1.5 mgm./kgm., or 3.0 mgm./kgm, of chlorpromazine and found an incr
