Delivery of response-independent food during intertrial intervals (ITI) of fixed-interval (FI) schedules was used to examine the resistance to change of temporal control in pigeons. After response rates stabilized on an FI 150 s ITI 135 s, response-independent food was delivered at the beginning of the ITI in one condition and at the end of the ITI in a separate condition (Experiment 1). The ITI then was shortened to 35 s and the same conditions were examined. In Experiment 2, these same conditions were examined, but with responding maintained by an FI 30-s schedule. Differential effects of food location were not obtained in either experiment. The results are discussed in relation to such parameters as delay of disruption, disrupter frequency, ITI duration and general resistance to change of FI schedules.
