Specific schedules of reinforcement reliably induce specific patterns of response, irrespective of the species being investigated (including humans in some conditions). However, the quantitative properties of behavior under a given schedule depend on the parameters of the schedule, and sometimes on other, non-schedule factors. The orderliness and predictability of behavior under schedules of reinforcement was evidence for B.F. Skinner's claim that by using operant conditioning he could obtain "control over behavior", in a way that rendered the theoretical disputes of contemporary comparative psychology obsolete. The reliability of schedule control supported the idea that a radical behaviorist experimental analysis of behavior could be the foundation for a psychology that did not refer to mental or cognitive processes. The reliability of schedules also led to the development of applied behavior analysis as a means of controlling or altering behavior.
