Three experiments attempted to determine which properties of pictorial representations of objects control their discrimination by pigeons. A particular focus was whether the representation mediating such discriminations could be described by the simple viewpoint-invariant primitive volumes of Biederman's (1987) recognition-by-components theory of object recognition or by Cerella's (1990) particulate features. In all 3 experiments, pigeons were first trained to discriminate drawings of 4 stimulus objects with half of the contour deleted but with the component geons postulated by Biederman's theory recoverable. Discrimination accuracy was then compared for test items containing the original particulate features, affording the retrieval of the original component geons, or having neither of these properties of the training stimuli. Although response accuracy was significantly greater when the component geons of the original objects were retrievable, measurable control over recognition by the particulate features of the objects and by their specific locations was also found. The results are consistent with the idea of component geon recognition as one of the important factors in object discrimination.
三项实验试图确定物体的图像表征的哪些属性控制着鸽子对它们的辨别。一个特别的关注点是，介导这种辨别的表征能否用比德曼（1987年）的物体识别部件识别理论中简单的视角不变基本体积来描述，或者用塞雷拉（1990年）的颗粒特征来描述。在所有三项实验中，鸽子首先接受训练，以辨别4个刺激物体的绘图，其中一半轮廓被删除，但比德曼理论假设的部件geon仍可恢复。然后比较测试项目的辨别准确率，这些测试项目包含原始颗粒特征、能够恢复原始部件geon，或者既不具备训练刺激的这些属性。尽管当原始物体的部件geon可恢复时，反应准确率显著更高，但也发现了物体的颗粒特征及其特定位置对识别有可测量的控制作用。结果与部件geon识别是物体辨别中的重要因素之一这一观点一致。
