Abstract

A cebus monkey was trained to hold a continuously moving voltmeter needle on-target for 60 seconds to obtain a food-pellet reinforcement. The task confronting the animal was relatively complex in that the high-frequency error voltage fed to the voltmeter needle was nulled by the animal by means of a joystick physically separated from the stimulus display.
