翻译后摘要：摘要我们提出了一种新的现象，涉及吸积删除，图形-地面解释，从运动的结构之间的相互作用。我们的显示器包含交替的亮和暗垂直区域，其中随机点纹理以恒定速度水平移动，但在交替区域中以相反的方向移动。这种运动与前面所有的亮区一致，暗区在背景中以非模态方式完成一个大的表面移动，反之亦然。令人惊讶的是，被认为是图形的区域也被认为是在深度上旋转的3D体积（像旋转的柱）-尽管点的运动与3D旋转并不一致。在一系列的实验中，我们发现我们可以简单地通过改变已知的几何线索来操纵哪些区域被感知为旋转体积，包括凸性，平行性，对称性和相对面积。受试者指出他们认为旋转的彩色区域。对于我们的显示器，我们发现凸性是一个比对称或平行更强的线索。此外，我们还发现了一个平稳的单调衰减的比例，受试者认为对称区域的图形，作为其相对面积的函数。我们的研究结果揭示了一个有趣的新的相互作用之间的吸积删除，图形地面，和3-D运动，是没有捕捉到现有的模型。它们也为测量图形-背景知觉提供了一个有效的工具。
Abstract:Abstract We present a novel phenomenon involving an interaction between accretion deletion, figure-ground interpretation, and structure-from-motion. Our displays contain alternating light and dark vertical regions in which random-dot textures moved horizontally at constant speed but in opposite directions in alternating regions. This motion is consistent with all the light regions in front, with the dark regions completing amodally into a single large surface moving in the background, or vice versa. Surprisingly, the regions that are perceived as figural are also perceived as 3-D volumes rotating in depth (like rotating columns)—despite the fact that dot motion is not consistent with 3-D rotation. In a series of experiments, we found we could manipulate which set of regions is perceived as rotating volumes simply by varying known geometric cues to figure ground, including convexity, parallelism, symmetry, and relative area. Subjects indicated which colored regions they perceived as rotating. For our displays we found convexity to be a stronger cue than either symmetry or parallelism. We furthermore found a smooth monotonic decay of the proportion by which subjects perceive symmetric regions as figural, as a function of their relative area. Our results reveal an intriguing new interaction between accretion-deletion, figure-ground, and 3-D motion that is not captured by existing models. They also provide an effective tool for measuring figure-ground perception.
