Visual cliff behavior was studied in 120 chicks as a function of 22, 46, 70, 94, or 118 hr of rearing in a deep or shallow environment. Preference for the deep side of the visual cliff increased directly with duration of depth-rearing but was uninfluenced at any duration of shallow-rearing. Although qualitative differences existed in the behaviors of those shallow- and deep-reared chicks which crossed the cliff, the loss of depth avoidance by the latter group appeared to be specific to the rearing and testing apparatus.
对120只小鸡的视崖行为进行了研究，该行为是在深或浅环境中饲养22、46、70、94或118小时的函数。对视崖深侧的偏好随深度饲养时间的增加而直接增加，但在任何浅度饲养时间内均不受影响。尽管跨越视崖的浅度和深度饲养小鸡的行为存在质的差异，但后一组深度回避行为的丧失似乎特定于饲养和测试装置。
