Light aversion of normal and posterior neodecorticate rats

An Erratum to this article was published on 01 March 1976

Abstract

The light aversion behavior of normal rats and rats with posterior neocortex lesions was examined in a two-choice brightness (card) discrimination task. By varying pretraining procedures, normal rats could be shown to have apparent light preferences, light aversion, or no preferences. Neither normal rats nor lesioned rats showed light avoidance tendencies in tasks in which pretraining biases were removed. The results indicate that the light avoidance tendencies shown by the normal or lesioned rats in free choice tasks are not reflected on card discrimination tasks.
