Document Summary
Perception: the processing of information from the body or environment and its transformation into meaningful representations that can be used in the service of reasoning and action. Visual perception is the process of converting light information into information that can be used by a perceiver. Rods: the most light sensitive photoreceptive cells in the retina. Good for monochrome vision in low light (night vision) Correspond to short (blue), medium (green) and long wavelengths (red) Fewer cone cells exist for peripheral vision not a lot of colour in our peripheral. Some people have 4 types of cones. The mantis shrimp has 16 cones, most complex visual system. Our retina is flawed because our retina is inside out. Size: we know how big objects are. Perspective: objects are smaller on the fovea as they get farther away. Occlusion: when one object is in front of another.
