关于双眼抑制的发展时间我们知之甚少。在目前的研究中，我们使用持续闪光抑制(CFS)来评估婴儿出现双眼抑制的情况。在我们的实验中，婴儿的一只眼睛被呈现在屏幕的一侧，而另一只眼睛被呈现为全屏幕的动态蒙德里安图案。成人观察者证实，静止的面孔图像被不断变化的蒙德里安图案有意识地压制住了。如果双眼抑制是起作用的，婴儿将不会感知到脸，因此在实验中不会表现出任何偏好。然而，如果婴儿还没有获得双眼抑制，他们会同时感知面孔和蒙德里安图案，因此会显示出对呈现面孔的一侧的偏好。结果表明，2-3个月大的婴儿能探测到脸部的位置，而4-5个月大的婴儿则不能。此外，这种检测并不是由于对动态蒙德里安掩模的弱对比度敏感性。这些结果表明，不成熟的双眼视觉系统可以同时从不同的眼睛感知不同的图像，婴儿在4-5月龄时建立双眼抑制后可能会失去这种能力。
Little is known about the time of development of binocular suppression. In the present study, we evaluated the emergence of binocular suppression in infants by using continuous flash suppression (CFS,). In our experiment, one eye of infants was presented with a static face image at one side of the screen, while another eye was presented with dynamic Mondrian patterns in full screen. Adult observers confirmed that the static face image was consciously repressed by the changing Mondrian patterns. If binocular suppression was functional, the infants would not perceive the face and thus would not show any preference in the experiment. However, if binocular suppression in the infants was not yet acquired, they would perceive the face and the Mondrian patterns at the same time and would thus show preference for the side where the face was presented. The results showed that infants aged 2–3 months, but not those aged 4–5 months, detected the position of the face. Furthermore, this detection was not due to weak contrast sensitivity to the dynamic Mondrian mask. These results indicated that the immature binocular visual system may perceive different images from different eyes simultaneously and that infants may lose this ability after establishing binocular suppression at 4–5 months of age.
