Responding in two rats was maintained under mixed and multiple variable‐interval 35‐sec variable‐interval 35‐sec food delivery schedules. Similar rates and patterns of responding occurred in each component of the two schedules. Mixed and multiple variable‐interval 65‐sec variable‐interval 65‐sec schedules of response‐dependent shock delivery were superimposed on the mixed and multiple baseline food schedules, respectively. In one component, a 5‐sec stimulus was presented on the average of once every 65 sec. Offset of the stimulus arranged that the next response would produce shock. In the other component, no stimulus was presented during the 5‐sec period. The mixed schedule of signalled and unsignalled dependent shock delivery yielded similar degrees of response suppression in each component, but the multiple schedule of shock delivery revealed differential degrees of response suppression. Considerably more suppression occurred in the component not associated with the preshock stimulus, thus implicating the discriminative functions of the correlated stimulus.
