Document Summary
Monocular cues: cues that work with only one eye, also called pictorial depth cues they are present in pictures. Physical changes that occur in our eyes as we look at the world: accommodation, lens changes shape depending on proximity of the object. Relaxation of ciliary muscles for far objects (more flat) Contraction of ciliary muscles for near objects (more rounded and contracts) The perceptual completion of the occluded figure is called amodal completion physical stimuli to support the conclusion. Figures closer to a light source will be brighter (further away will be in shadow) The missing parts of the figure are perceptually present even though there are no: shadows, perceived as 3d image. Gives info about the shape of an object on the surface. Shading from dark to light gives us the 3d picture. We rely on shadows and assumptions about light sources. Most we are exposed from the lights that come from above (ex. sun,lights in the ceiling)
