Abstract

Abstract We tested the monocular visual field of 16 kittens aged 13–56 days, by observing their unreinforced visual orienting. At 13–14 days the kittens oriented toward stimuli out of 45° in the temporal visual field, but no further than 15° in the nasal field. Until 7–8 weeks, performance was significantly poorer in the nasal field than in the temporal field. This delayed development of the nasal field may be related to the relatively slow development of the uncrossed retino-geniculate projection and of the pathway through the visual cortex to the superior colliculus.
