Sensitivity to static pictorial information for depth develops between 22 and 26 weeks of age. When conflicting binocular and surface-texture information was minimized, 26- to 30-week-old infants directed their reaching to the apparently closer side of a photograph of a window rotated in depth. Younger infants, from 20 to 22 weeks of age, did not direct their reaching to the pictorially nearer side of the display but did reach with a high degree of directionality when presented with a real window rotated in depth.
对深度静态图像信息的敏感度在22至26周龄之间发展。当双眼和表面纹理信息的冲突最小化时，26至30周龄的婴儿会将伸手动作指向深度旋转的窗户照片中看起来较近的一侧。20至22周龄的较小婴儿不会将伸手动作指向显示器上图像较近的一侧，但当呈现深度旋转的真实窗户时，他们确实会以高度的方向性伸手。
