Abstract: The purpose of this experiment was to assess the effects of a variable-interval changeover contingency on both main-key and CO-key behavior. This contingency was varied from 5 to 160 sec. The major concern was whether response and time matching would occur as has been reported to occur when a changeover delay is varied. Like the changeover delay, varying the variable-interval changeover contingency produced a decrease in the CO rate; however, unlike the COD, large deviations from matching occurred. When the response and time distributions were recomputed so as to include the CO-key behavior, more of the response and time distribution points fell within the matching range. The role of CO contingencies in concurrent schedules was considered. Since the present procedure has certain formal similarities to a CO-key concurrent chains schedule, it was of interest to determine if the relative response rates on the CO-key would match the relative rates of reinforcement on the main-key. Such matching did not occur. Differences in programming between the present procedure and the usual two-key procedure were discussed.
