Abstract
Pigeons trained on a series of color-discrimination reversals were presented either reward or extinction single-stimulus pretraining at various points during reversal learning improvement. Extinction of the previous S+ facilitated reversal learning more than reward of the previous S-, with this relation remaining unchanged throughout training.
