Examined the behavior of 105 male guinea pigs (cavia porcellus) in a 2-way active-avoidance box using an auditory cs under several conditions of modified visual input. Ss which had been blinded, had been trained in darkness, had received lesions of posterior neocortex, or were both blind and posterior neodecorticate behaved more efficiently than normal and operated controls. The facilitating effect of blinding was eliminated by prohibiting spontaneous crossings during the iti. (PsycINFO Database Record (c) 2006 APA, all rights reserved)
