Recent research shows that young infants are sensitive to motion parallax in visual displays but leaves open the question of whether infants use the information to perceive spatial layout. In this experiment, 6-month-old infants were translated horizontally in front of two objects that were yoked to the infant's movement. One object moved in the same direction as the motion of the infant and the other object moved in the opposite direction. This event provided motion parallax information that the object that moved in the opposite direction was nearer in depth. Infants who viewed the display monocularly reached preferentially to the object that was apparently nearer. A control group of infants who viewed the display binocularly showed no such preference. These results provide the first direct evidence that young infants use the spatial information provided by motion parallax to perceive the relative distance of objects and to direct their actions accordingly.
最近的研究表明，年幼的婴儿对视觉显示中的运动视差很敏感，但仍不清楚婴儿是否会利用这些信息来感知空间布局。在这个实验中，6 个月大的婴儿在两个与婴儿运动相配合的物体前被水平平移。一个物体的运动方向与婴儿的运动方向相同，另一个物体的运动方向与婴儿的运动方向相反。这个事件提供了运动视差信息，即运动方向相反的物体在深度上更近。单眼观看显示的婴儿更倾向于到达那个显然更近的物体。观看显示的双眼对照组的婴儿没有表现出这种偏好。这些结果提供了第一个直接证据，表明年幼的婴儿使用运动视差提供的空间信息来感知物体的相对距离，并相应地指导他们的行动。
