Pigeons' responses on either of two concurrently available keys each associated with variable interval 60 sec schedules occasionally changed the schedule on that key to a terminal link interval schedule providing access to gain while the other key became inoperative. Experiment I compared simple fixed and mixed interval schedules in the terminal links, and showed that for all subjects and schedules the distribution of responses during the concurrent initial links was accurately described by the relative inverse delay of reinforcement squared. Experiment II extended the generality of this formulation to a situation in which rate of reinforcement was constant and delay alone was varied.
