Stereograms were presented in a two-choice preference procedure. The mean age at which stereopsis was first demonstrable was 16 weeks. By a mean age of 21 weeks, infants had achieved stereoacuity of 1 minute of arc or better. In comparison with the relatively slow development of visual acuity, the time course for the development of stereoacuity is extremely rapid.
立体图通过二选一偏好程序呈现。首次可证明立体视的平均年龄为16周。到平均年龄21周时,婴儿已达到1分视角或更好的立体视锐度。与视敏度相对缓慢的发育相比,立体视锐度的发育进程极其迅速。
