We examine the factors that lead to the identification advantage for real objects over line drawings in agnosia. In a single case study we show that identification is improved when shading cues can be used to guide the segmentation of objects into their parts. In addition we demonstrate that depth information, conveyed both by binocular disparity cues and by head movements, also facilitates object segmentation. The data indicate that information about depth and surface shading can contribute to object recognition in cases where edge-based object coding is impaired.
我们研究了导致失认症患者对真实物体的识别优势超过线条图的因素。通过一项单一的案例研究，我们表明，当可以使用阴影线索来引导物体分割成其各个部分时，识别能力会提高。此外，我们还证明了深度信息，包括双目视差线索和头部运动所传达的信息，也有助于物体分割。这些数据表明，在基于边缘的物体编码受损的情况下，关于深度和表面阴影的信息可以有助于物体识别。
