In 2 experiments the performance of 90- and 150-day-old light-reared and dark-reared rats was compared under appetitive reinforcement conditions on rigorous tests of form discriminative abilities. Although early stimulatory history had little impact on either the ability to discriminate shapes on the basis of contour orientation or to generalize from that initial experience to lines in other orientations lack of visual experience did have significant consequences with respect to a comparable task in which the relationship between lines was the significant feature. Little change in the initial deficits was observed with exposure to a normal light environment for 60 days following the period of early visual deprivation in the case of this 2nd complex pattern discrimination task.
在2项实验中，对90日龄和150日龄的光照饲养和黑暗饲养大鼠在食欲强化条件下进行严格的形状辨别能力测试时的表现进行了比较。尽管早期刺激经历对基于轮廓方向辨别形状的能力，或从该初始经验推广到其他方向线条的能力影响不大，但缺乏视觉经验对于线条之间的关系为显著特征的类似任务确实产生了重大影响。在第二项复杂图案辨别任务中，在早期视觉剥夺期后暴露于正常光照环境60天，初始缺陷几乎没有变化。
