Response strategy in two-choice visual discrimination in the rabbit

Abstract

Rabbits were trained to discriminate striated patterns of different orientation in a two-choice discrimination box. After the 90 percent correct level had been reached, motor behaviour was studied during visual discrimination. It was found that the animals made their decision after seeing one of the two stimuli. This finding is in disagreement with an earlier study from which it was concluded that the animal's choice is mainly controlled by the unrewarded stimulus (Van Hof and Van Hof-van Duin 1984).
