通过三个实验考察了深度视点和刺激类型(线条与轮廓)对图片识别的影响。这两个因素都有明显的效果。高度缩略的视图比更规范的视图更难识别，轮廓比线条图更难识别。此外，还有很强的互动性。如果展示的是剪影而不是线条，缩短的缺点就会大大增加。我们的结果表明，线条图(但不是轮廓)中可用的内部信息对于识别对象的缩短视图至关重要。来自不可知症患者HJA的其他结果表明，某些形式的脑损伤可以扰乱使用内部信息进行识别，减少线条画和剪影之间的差异。
Three experiments are reported into the effects of viewpoint in depth, and of stimulus type (line drawings vs silhouettes) on picture identification. Clear effects of both factors were observed. Strongly foreshortened views were harder to identify than more canonical views, and silhouettes were harder to identify than line drawings. Furthermore, there was a strong interaction. The foreshortening disadvantag e was greatly increased if silhouettes rather than line drawings were presented. Our results suggest that the internal information available in line drawings (but not silhouettes) is critical for identifying foreshortened views of objects. Additional results from an agnosic patient, HJA, suggest that certain forms of brain damage can disrupt the use of internal information for identification, reducing differences between performance with line drawings and silhouettes.
