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 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. Perceiving in Depth Volume 1 Basic Mechanisms
Howard details historical display systems like panoramas, peepshows, and the invention of the stereoscope, which first allowed humans to artificially simulate depth. The book outlines the precise behavioral and analytic
The book emphasizes "experience-dependent" neural plasticity—the idea that the brain's visual circuits must be "tuned" by environmental stimuli during early development to function correctly. and the invention of the stereoscope
Howard provides a comprehensive review of how depth perception matures from the embryonic stage to post-natal life.
Howard explores how the brain translates raw light signals into meaningful geometric representations of space.
