In two experiments, we investigated the ability of younger and older observers to perceive and discriminate 3-D shape from static and dynamic patterns of binocular disparity. In both experiments, the younger observers' discrimination accuracies were 20% higher than those of the older observers. Despite this quantitative difference, in all other respects the older observers performed similarly to the younger observers. Both age groups were similarly affected by changes in the magnitude of binocular disparity, by reductions in binocular correspondence, and by increases in the speed of stereoscopic motion. In addition, observers in both age groups exhibited an advantage in performance for dynamic stereograms when the patterns of binocular disparity contained significant amounts of correspondence "noise." The process of aging does affect stereopsis, but the effects are quantitative rather than qualitative.
在两项实验中，我们研究了年轻和年长观察者从双眼视差的静态和动态模式中感知和辨别三维形状的能力。在两项实验中，年轻观察者的辨别准确率比年长观察者高20%。尽管存在这种数量上的差异，但在所有其他方面，年长观察者的表现与年轻观察者相似。两个年龄组都同样受到双眼视差大小变化、双眼对应性降低以及立体运动速度增加的影响。此外，当双眼视差模式包含大量对应“噪声”时，两个年龄组的观察者在动态立体图的表现上都具有优势。衰老过程确实会影响立体视觉，但影响是数量上的而非质量上的。
