通过观察16只13-56日龄幼猫的非强化视觉定向，对幼猫的单眼视野进行了测试。在13-14日龄时，小猫在颞侧视野中朝向45°以外的刺激，但在鼻侧视野中不超过15°。直到7-8周，鼻区的表现明显差于颞区。鼻野发育的延迟可能与非交叉的视网膜膝状体投射和通过视皮层到上级丘的通路发育相对缓慢有关。
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.
