Abstract

A three-operanda procedure was used to study the behaviur of rats on concurrent variable-interval, variable-interval schedules. Iii Experiment 1 this new procedure was cornpared to the known “two-bar” and “changeover bar” procedures when the length of a changeover delay was vaxied. Iii Experiment 2 the three-operanda procedure was used, withuut a changeover delay, and diffcrent palis uf concurrent schedules were used lii six experimental conditions. The absence of a changeover delay did not preclude the observatiun of lawful relationships between behavior and consequences. Results indicated that with a procedure in which each schedule is associated with a different operandum, and changeovers are topugraphkally different from concurrent operants, relative behavior rneasures are sensitive tu relative reinforcement rate, even with ram as subjects.
