A detailed analysis covers how disruptions during these critical periods—such as strabismus (crossed eyes) or monocular deprivation—can lead to permanent defects like amblyopia (lazy eye) or a total loss of stereoscopic vision.
Howard details historical display systems like panoramas, peepshows, and the invention of the stereoscope, which first allowed humans to artificially simulate depth. Perceiving in Depth Volume 1 Basic Mechanisms
The book outlines the precise behavioral and analytic procedures used to measure how subjects respond to visual stimuli, establishing the rigorous scientific standard for modern depth research. The Biological Machinery of Vision A detailed analysis covers how disruptions during these
