以往的研究定义的感知透明度的光度条件下，两个表面之间的感知深度排序变得模棱两可。即使在这种非透明条件下，深度顺序感知也常常偏向于一种特定的解释（Beck，Prazdny，& Ivry，1984; Delogu，Fedorov，Belardinelli，&货车Leeuwen，2010; Kitaoka，2005; Oyama & Nakahara，1960）。在这项研究中，我们研究了是什么决定了感知深度排序的透明模式，使用刺激，模拟两个部分重叠的磁盘导致四个区域：a（背景），B（部分右磁盘），p（部分左磁盘），和q（共享区域）。与先前提出的对比度对背景区域的贡献（即，轮廓B/a处的对比度和轮廓p/a处的对比度）与在双透明图案中感知的深度顺序的关系，本研究表明与对共享区域的对比度相比，对背景区域的对比度对感知的深度顺序的影响很小（即，轮廓B/q处的对比度和轮廓p/q处的对比度）。此外，我们发现，感知深度排序是很好的预测一个更简单的模型，只考虑相对大小的亮度差异对共享区域。具体地说，左圆盘被感知为在前面的概率与（|B - q| - |p - Q|) / (|B - q| + |p - Q|）基于亮度计算。
Previous studies on perceptual transparency defined the photometric condition in which perceived depth ordering between two surfaces becomes ambiguous. Even under this bistable transparency condition, it is known that depth-order perceptions are often biased toward one specific interpretation (Beck, Prazdny, & Ivry, 1984; Delogu, Fedorov, Belardinelli, & van Leeuwen, 2010; Kitaoka, 2005; Oyama & Nakahara, 1960). In this study, we examined what determines the perceived depth ordering for bistable transparency patterns using stimuli that simulated two partially overlapping disks resulting in four regions: a (background), b (portion of right disk), p (portion of left disk), and q (shared region). In contrast to the previous theory that proposed contributions of contrast against the background region (i.e., contrast at contour b/a and contrast at contour p/a) to perceived depth order in bistable transparency patterns, the present study demonstrated that contrast against the background region has little influence on perceived depth order compared with contrast against the shared region (i.e., contrast at contour b/q and contrast at contour p/q). In addition, we found that the perceived depth ordering is well predicted by a simpler model that takes into consideration only relative size of lightness difference against the shared region. Specifically, the probability that the left disk is perceived as being in front is proportional to (|b - q| - |p - q|) / (|b - q| + |p - q|) calculated based on lightness.
