立体图是在一个两个选择的偏好程序。首次出现立体视觉的平均年龄为16周。到平均21周时，婴儿的立体视锐度达到1弧分或更好。与视力的相对缓慢的发展相比，立体视敏度的发展的时间进程是非常快的。
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.
