本研究探讨了不同的深度线索是否会与密度判断产生不同的相互作用。使用3D投影仪，我们在不同深度（距投影平面−30、−15、0、+15或+30厘米）的额平行方形平面上呈现随机点刺激，并使用恒定刺激的方法测量每个深度平面中点的感知密度。平面的深度是通过三种类型的深度线索（双眼视差、刺激区域和点大小）来操纵的，这些线索可以单独使用，也可以一起使用。结果表明，当深度线索为刺激区域时，平均PSE取决于深度平面，而大小和视差线索对PSE的影响相对较弱。然而，当这些线索结合起来时，区域线索对密度判断的影响就大大减弱了。这些发现意味着深度线索的组合可以提供更精确的点深度感知，并有助于解释“3D 有效密度”。
The present study examined whether different depth cues would interact with the judgment of density differently. Using a 3D projector, we presented random-dot stimuli on fronto-parallel square planes at different depths (−30, −15, 0, +15, or +30 cm from the projection plane) and measured the perceived density of the dots in each depth plane using the method of constant stimuli. The depth of the plane was manipulated with three types of depth cues (binocular disparity, stimulus area, and dot size), which were used separately or all together. The results showed that the averaged PSEs depended on the depth plane when the depth cue was stimulus area, whereas the influences of size and disparity cues on the PSE were relatively weak. However, when the cues were combined, the influence of the area cue on density judgment was largely attenuated. These findings imply that the combination of the depth cues can provide more precise depth perception of the dots and helping interpretations of "3D-valid density".
