To examine the effects of the temporal separation of multiple VI VI schedule components on differential resistance to change (DRTC), two experiments were conducted with rats. Reinforcement rates and magnitudes (reinforcers per cycle) were manipulated in Experiments 1 and 2, respectively, to produce rich and lean components. In both experiments, the separation of the components was manipulated by using different component durations, during one condition, and different intercomponent intervals (ICI), during another condition. Total exposure to the components was constant across sessions of each condition. Resistance to satiation was evaluated by delivering increasing amounts of the reinforcer before each test session. In Experiment 1, different component duration either increased (F2 and F4), decreased (F1 and F02), or had no consistent effects (F3) on DRTC. Increasing ICIs produced either an increase (F02) or an increase followed by a decrease (i.e., an inverted U function) in DRTC. In Experiment 2, increases in component duration produced either an increase (F6 and F8) or no consistent effects on DRTC. Increasing ICIs produced an increase (F7) or an inverted U effect on DRTC. Results are discussed in terms of the discrimininability of contingencies that are too close or too separate in time.
