A 1‐min tone and light signal that preceded two free pellets of food suppressed the random‐ratio responding of four rhesus monkeys, but accelerated the same subjects' responding on a differential‐reinforcement‐of‐low‐rate schedule in separate sessions. Both schedule‐specific interactions occurred during the first presentations of the signal that previously had been paired with food outside the operant sessions. Thus, neither effect was adventitiously produced. In two subjects, both the direction and magnitude of the prereward change in differential‐reinforcement‐of‐low‐rate responding appeared related to baseline response rates: the more rapid the baseline responding, the less was the acceleration during the signal. Suppression and acceleration did not appear as dichotomous effects with separate parameters, but as related effects at least partly determined by the characteristics of the baseline operant performance.
