Abstract
The response-independent, fixed-time delivery of electric tail shock in the squirrel monkey generated bites on a rubber hose immediately following shock delivery and manual responses on a lever immediately preceding shock. The procedure generated two temporally and topographically different responses in the single organism in a single experimental session. All responses were measured objectively via response manipulanda and recorded on cumulative recorders and counters. Nine pharmacological compounds were administered to the squirrel monkey after a stable baseline of bite and lever press responding had been established. Three stimulant compounds - d-amphetamine, caffeine, cocaine; three tranquilizer compounds - nicotine, chlordiazepoxide, chlorpromazine; and three sedative compounds - alcohol, phénobarbital, and morphine were administered on this baseline. The stimulant compounds had the general effect of elevating both responses; the tranquilizer compounds had the general effect of elevating lever press responding while depressing bite responding across a portion of the dosage range; the sedative compounds had the general effect of depressing both responses. Each compound had a differential effect on the response and a complete dose response function was obtained for each subject on each compound. The procedure appears to be a good one for testing behavioral effects of drugs. The responses are contingency free so that the effect of a drug cannot be to alter any response produced environmental consequences. The recording of two separate responses from one organism in a single experimental session allows for the measurement of selective and differential drug effects. The squirrel monkey subject is ideal also because it is a primate and close to the human in drug dosage ranges which enables the possibility of generalizing to the human.
