在目前的研究中，作者调查了地面优势效应（利用地面信息对场景进行知觉组织）是否随年龄而变化。在实验1中，一个场景包含地面，天花板，和2个垂直的职位。场景要么处于正常方向，要么旋转到一边。在实验2中，将一个蓝点附着到每个柱子上，位置从柱子的底部到顶部变化。实验三在视野的不同位置呈现与实验一相似的场景。观察者判断两个物体（实验I和3中的柱子，实验2中的蓝点）中哪一个看起来更近。结果表明，无论是年轻（平均年龄= 22岁）和老年观察员（平均年龄= 73岁）的反应一致的地面优势效应。然而，对于年龄较大的观察者，这种影响的程度有所下降。这些结果表明，减少使用地面信息的老年观察员的感知组织的场景布局。
In the current study, the authors investigated whether the ground dominance effect (the use of ground surface information for the perceptual organization of scenes) varied with age. In Experiment 1, a scene containing a ground, a ceiling, and 2 vertical posts was presented. The scene was either in its normal orientation or rotated to the side. In Experiment 2, a blue dot was attached to each post, with location varied from bottom to top of the posts. In Experiment 3, a scene similar to that in Experiment I was presented in different locations in visual field. Observers judged which of the 2 objects (posts in Experiments I and 3, blue dots in Experiment 2) appeared to be closer. The results indicated that both younger (mean age = 22 years) and older observers (mean age = 73 years) responded consistently with the ground dominance effect. However, the magnitude of the effect decreased for older observers. These results suggest a decreased use of ground surface information by older observers for the perceptual organization of scene layout.
