通过使用CRT显示器上呈现的照明表面的模拟，在两个实验中测量感知透明度。在一个二选一的强迫选择范例中，观察者按时间顺序观察两个模拟的蒙德里安。在一个序列中，蒙德里安被模拟为被透明滤光片部分覆盖;在另一个序列中，每个蒙德里安补丁上的滤光片颜色被修改。指导观察员选择含有透明滤光片的序列。观察者的选择对应于这样的序列，其中每个相邻的蒙德里安斑块对的锥体激发比与被过滤器覆盖的斑块对的锥体激发比大致相同。结果表明，锥兴奋比可能是知觉透明度的线索。(C)2003年美国光学学会。
Perceptual transparency was measured in two experiments by using simulations of illuminated surfaces presented on a CRT monitor. In a two-alternative forced-choice paradigm, observers viewed two simulated Mondrians in temporal sequence. In one sequence the Mondrian was simulated to be partially covered by a transparent filter; in the other sequence the filter color over each Mondrian patch was modified. Observers were instructed to select the sequence containing a transparent filter. Observers' selections corresponded to sequences in which the cone-excitation ratios for each adjacent pair of Mondrian patches were approximately the same as the cone-excitation ratios for the pair of patches covered by a filter. The results suggest that cone-excitation ratios may be a cue for perceptual transparency. (C) 2003 Optical Society of America.
