“Kittens were reared in total darkness from birth to six weeks of age. From six weeks of age until the end of the study they lived under the following binocular conditions: (a) 1 hr. a day, diffused light stimulation in a holder; (b) 1 hr. a day, pattern vision in a holder; (c) 1 hr. a day, pattern vision in an exercise pen; and (d) 24 hr. a day, ”normal“ laboratory environment.” Monocular discrimination training was begun at 14 to 18 weeks of age. Animals in conditions (a) and (b) failed to learn a movement discrimination but learned an intensity discrimination as readily as the others. “All control Ss showed good performance of the movement discrimination when shifted to the use of the untrained eye.” There were no differences between groups in interocular transfer of intensity discriminations.
