LEVER DISPLACEMENT DURING A DISCRIMINATION DIFFERENTIATION
Abstract
The maximum displacement of the T-bar handle of a rat response lever was recorded under two schedules: (a) programmed variable-duration S to the exponent and S to the exponent delta periods with reinforcement only for S to the exponent presses between 23.54 degrees and 28.64 degrees (Position 5) and (b) the same requirements for a reinforcement as in (a) but with S to the exponent delta initiated only by a ''wrong'' press in S to the exponent, and prolonged by any press in S to the exponent delta. With this lever, work is linearly proportional to displacement. Under the first schedule (a) S to the exponent distributions differed significantly from their companion S to the exponent distributions, although the lever position showing the greatest percentage of presses in S to the exponent often corresponded with the one showing the greatest percentage in S to the exponent delta and (b) both mean lever displacement and variability were consistently greater in S to the exponent delta than in S to the exponent. Under the second schedule (a) S to the exponent distributions differed significantly from their companion S to the exponent delta dis tributions, but the S to the exponent - S to the exponent delta distributions were positively correlated and (b) mean lever displacement was about the same in S to the exponent and S to the exponent delta, but variability was consistently greater in S to the exponent delta.
