Sensitivity to Three-Dimensional Orientation in Visual Search

James T. Enns, Ronald A. Rensink
1990 Psychological Science  
It is shown here that search can also be based on three-dimensional orientation of objects in the corresponding scene, provided that these objects are simple convex blocks.  ...  Previous theories of early vision have assumed that visual search is based on simple two-dimensional aspects of an image, such as the orientation of edges and lines.  ...  Many of the target and distractor items were projections of rectangular objects differing in the three-dimensional orientation of their principal axes.  ...
