Axis of Elongation Can Determine Reference Frames for Object Perception

Object perception remains constant in the face of much retinal image variability. One way to achieve such constancy is to represent objects with respect to a reference frame, and many theories of object recognition assume that, among other factors, observers use objects' primary axes of elongation to derive reference frames. However, the limited research directly addressing this assumption suggests that the role of axis of elongation may not be …
