Four pigeons served in an experiment in which concurrent variable interval, variable interval schedules programmedrcinforcers independently of the subjects' behavior. Once a reinforcer was set up, timing for the next reinforcer began,regardless of the last reinforcer being delivered or not. Scheduled relative reinforcer frequency was kept constant while scheduledreinforcer frequency was manipulated (from 2 to 30 reinf/ min) in five experimental conditions. There was no scheduledconstraint for changeovers. Response distribution was close to reinforcer distribution for all four pigeons in all experimentalconditions. No systematic effect of absolute reinforcer frequency on the relationship between response and reinforcer distributionswas observed. The data do not support claims that the generalized matching equation should be replaced by an equationthat includes absolute reinforcer frequency as a variable.
