Shape constancy is the ability to perceive an object as maintaining its shape despite changes in the retinal image. In this case, even though the image on the retina is trapezoidal, we still perceive the window as rectangular due to our ability to maintain shape constancy. Size constancy pertains to perceiving objects as maintaining their size despite changes in the retinal image, figure-ground constancy pertains to the ability to perceive an object as a distinct entity from its background, and the phi phenomenon pertains to perceiving motion in a series of still images. None of these concepts explain why we perceive the window as rectangular from a side angle.
