Lever Pressing

3 rhesus monkeys were given various concentrations of sucrose for lever pressing on a variable interval schedule of reinforcement. 7 sucrose concentrations were studied at 2 levels of food deprivation. The response rates accelerated rapidly with increasing concentrations, and then declined after reaching a maximum, generally between 15 and 30% sucrose concentration. The decline was attributed to a satiation effect. The higher level of food deprivation tended to increase the response rate at all but the extreme high and low concentrations.

Response Facilitation

Gradually increased electric shock was superimposed on responding maintained on a VI 60-sec. schedule of reinforcement. Shock was contingent upon the reinforcement producing response and preceded reinforcement delivery. Following total response suppression, shock was removed and then reintroduced at selected intensities. The previously observed monotonic linear relationship between rate of responding and shock intensity was not recorded. Rather, post-reinforcement response bursts and two distinct patterns of response facilitation emerged.
