The development of vernier acuity was assessed in nine kittens using offsets in a series of square-wave gratings as stimulus targets. The kittens were tested on a jumping stand in a two-choice simultaneous discrimination paradigm, and daily thresholds were tracked with a modified staircase procedure. Vernier acuity improved gradually from initial values of 13-57' arc and reached asymptote at 1.5-5.4' arc by 70-90 days of age. The developmental function for vernier acuity is discussed in relation to physiologic development of the kitten visual system and is related to published data on the development of stereoacuity and spatial resolution in the same species.
使用一系列方波光栅中的偏移量作为刺激目标，对9只小猫的游标视力发育情况进行了评估。这些小猫在跳跃台上采用二选一同时辨别范式进行测试，并通过改良的阶梯程序跟踪每日阈值。游标视力从最初13 - 57弧分的值逐渐提高，到70 - 90日龄时在1.5 - 5.4弧分达到渐近值。本文讨论了游标视力的发育函数与小猫视觉系统生理发育的关系，并与同一物种中立体视敏度和空间分辨率发育的已发表数据相关。
