“…Recently, both Jagielo and Zentall (1986) and Parker and Glover (1987) also obtained evidence inconsistent with the rehearsal/surprise interpretation of retroactive interference in pigeons. Although Jagielo and Zentall's (1986) experiments were not designed specifically to assess retroactive interference effects, pigeons were tested on delayed matching trials in which the chamber was at times dimly illuminated and at other times brightly illuminated. They found higher levels of matching accuracy on trials in which the chamber was dimly illuminated than on trials in which the chamber was brightly illuminated.…”

In two experiments, independent groups of pigeons were trained on an identity matching task involving line orientations as sample and comparison stimuli. For some birds an overhead houselight was illuminated continuously throughout each training session. For other birds the houselight was never illuminated during training sessions. During subsequent testing, the lighting conditions during the delay were the same as in training on some trials, but on other trials they were opposite those of training during either the entire delay (Experiment 1) or during a portion of the delay (Experiment 2). In birds trained with the houselight off, turning the houselight on during the delay produced a large and enduring disruption in matching accuracy. On the other hand, in birds trained with the houselight on, turning the houselight off during the delay produced only a moderate and temporary disruption in matching accuracy. These findings are inconsistent with the prevailing view that retroactive interference in pigeons is a function of a change in illumination level relative to that which prevailed during training. In pigeons, as in monkeys, sustained retoactive interference effects obtain only when the level of illumination is increase during the delay interval.
