Abstract
Two discrimination-reversal indices, independently conceived by the authors, are compared and contrasted. The indices avoid many of the complications involved in the method of directly comparing absolute performance levels of diverse species. Each index provides a ratio score which relates reversal performance to acquisition performance on visual discrimination tasks.
