研究了人类受试者在试图学习放置在可绕其垂直轴自由旋转的支架上的物体的表面外观时分配时间的方式。进行实验，以确定观察者是否集中他们的时间在特定的意见，如果是这样的话，以确定图像的特点，首选的意见。对于四面体，受试者专注于呈现以视线为中心的面或边的视图。这两个视图关于垂直轴对称。以土豆作为不透明光滑物体的例子，受试者集中在四个视图上，其中物体的主（长）轴与他们的视线侧或端。对于这样的视图，对象图像的水平宽度（和表面积）有最大值和最小值。首选的意见是没有系统相关的意见定义为稳定的表面边界或“奇点”的外观。
The way in which human subjects distribute their time when attempting to learn the surface appearance of objects placed on a stand free to rotate about its vertical axis was investigated. Experiments were undertaken to establish whether observers concentrate their time on particular views and, if so, to determine the image characteristics of the preferred views. For tetrahedra, subjects concentrated on views which presented a face or an edge centred on the line of sight. Both of these views were symmetric about the vertical axis. For potatoes as examples of opaque smooth objects, subjects concentrated on four views in which the object's principal (long) axis was oriented side-on or end-on to their line of sight. For such views the horizontal width (and surface area) of the object's image had maximum and minimum values. Preferred views were not systematically related to views defined as stable from the appearance of surface boundaries or ‘singularities’.
