Based on Gibson's hypothesis that accretion and deletion of texture in the optic array provides unambiguous information for the spatial layout of surfaces, we sought evidence of early responsiveness to this information with infant subjects. 5- and 7-month-olds viewed computer-generated random-dot displays in which accretion and deletion of texture provided the only information for contours, specifying either a foreground surface moving in front of and occluding a moving background surface or 2 partially overlapping surfaces. The infants in both age groups showed significant preferences to reach for the apparently nearer regions in the displays. Since previous research has shown that infants reach more frequently for the nearer of 2 surfaces, these results indicate that 5- and 7-month-olds are sensitive to accretion and deletion of texture as information for the spatial layout of surfaces.
基于吉布森的假设，即视觉阵列中纹理的增减为表面的空间布局提供了明确的信息，我们试图寻找婴儿受试者对该信息早期反应的证据。5个月和7个月大的婴儿观看计算机生成的随机点显示，其中纹理的增减是轮廓的唯一信息，指定了一个前景表面在移动的背景表面之前移动并遮挡它，或者两个部分重叠的表面。两个年龄组的婴儿都表现出明显的偏好，即伸手去触摸显示器中明显更近的区域。由于先前的研究表明，婴儿更频繁地伸手去触摸两个表面中较近的那个，这些结果表明，5个月和7个月大的婴儿对纹理的增减很敏感，因为这是表面空间布局的信息。
