Resumo
The present experiment analyzed temporal control of postreinforcement pause duration during within‐session changes in the criterion for reinforcement (interfood interval, IFI). Analysis of interval‐by‐interval changes in the pause revealed localized and nonlocalized effects from short intervals that caused specific changes in performance. In Phase 1, rats were presented with five consecutive 15‐s IFIs intercalated into a series of 60‐s IFIs. The 15‐s set decreased the pause in adjacent and more remote 60‐s intervals. In Phase 2, two sets of 15‐s intervals were intercalated. The spacing between the two sets varied so that 0, 5, 10, or 15 60‐s IFIs separated the sets. The postreinforcement pause tracked all changes in the IFI duration, and the localized effect from a short set extended beyond the next interval to the next few 60‐s IFIs. Effects from one set, however, did not combine with a second set: Changes in the pause after two sets were the same regardless of the spacing between sets.
