In 2 experiments the behavior of light- and dark-reared infant- and adult-operated striate rats were compared at 20-160 days of age on a visual cliff apparatus in which the depth of the deep side could be varied. Differential depth thresholds revealed that depth discriminative ability did not develop normally following removal of the striate cortex in infancy. Further, infant-operates who were reared in darkness following their operations performed less well than their light-reared, infant-operated counterparts. The infant-operated animals, regardless of their postoperative rearing condition, performed significantly better than did adult-operated animals after comparable post-operative recovery periods and testing. The results are discussed in terms of further specification of the role played by age of operation and by the interaction between visual experience and age of operation.
在两项实验中，对出生后即摘除纹状皮层的幼年和成年大鼠在20至160日龄时的行为进行了比较，实验采用了视觉悬崖装置，深侧的深度可以变化。差异深度阈值显示，婴儿期摘除纹状皮层后，深度辨别能力未能正常发育。此外，术后在黑暗中饲养的幼年手术大鼠比在光照下饲养的同类表现更差。在术后恢复期和测试相当的情况下，幼年手术动物，无论其术后饲养条件如何，其表现都明显优于成年手术动物。根据手术年龄以及视觉经验与手术年龄之间的相互作用所起的作用的进一步细化，对结果进行了讨论。
