Science, 1961•science.orgFour rats were trained to press a lever on a ratio schedule of reinforcement in which the
number of lever presses required on each consecutive run increased by a fixed increment.
Both concentration and volume of the reward were varied. Relationships were obtained
between reward and deprivation variables and the size of the final completed ratio run.
