以往关于深度线索组合的研究通常假设不同的线索必须在相同的单位中才能发生有意义的组合。我们研究了当双眼视差提供明确的度量信息时，熟悉性和凸性的几何顺序线索是否会影响深度知觉。我们使用二分的，随机点立体图，中央亮度边缘形状像一个脸的轮廓。视差指定一侧的边缘和点比另一侧的点更接近。结构线索表明，熟悉的，脸状的区域比不熟悉的一侧更近。配置线索引起的增加，在感知深度为一个给定的视差信号时，他们是一致的视差和减少时，他们是不一致的感知深度。因此，几何顺序的几何线索可以定量地影响度量深度线索。的组合的几何和深度线索的影响进行了讨论。
Prior research on the combination of depth cues generally assumes that different cues must be in the same units for meaningful combination to occur. We investigated whether the geometrically ordinal cues of familiarity and convexity influence depth perception when unambiguous metric information is provided by binocular disparity. We used bipartite, random dot stereograms with a central luminance edge shaped like a face in profile. Disparity specified that the edge and dots on one side were closer than the dots on the other side. Configural cues suggested that the familiar, face-shaped region was closer than the unfamiliar side. Configural cues caused an increase in perceived depth for a given disparity signal when they were consistent with disparity and a decrease in perceived depth when they were inconsistent. Thus, geometrically ordinal configural cues can quantitatively influence a metric depth cue. Implications for the combination of configural and depth cues are discussed.
