Document Summary
The process by which agents interpret and organize sensation to produce a meaningful experience of the world. From a cog sci perspective, it means turning information from one form into new, meaningful experiences. These are typical modalities, but we also have some atypical ones: senses in the bowel, stomach, pain receptors, heat receptors, etc. Rays of light emanating from the eye in combination with light in the world to allow us to see. Visual perception is accomplished by rays of light reflected from objects into the eyes. Light is reflected into the eye and focused on the retina. Light stimulates the rod and cone receptors. The image is severely distorted and inverted. There are three types of cones: correspond to short (blue, medium (green, long wavelengths (red); works best with bright light. Size: we know how big things are. Perspective: things are smaller on the fovea as they get farther. Occlusion: when one thing is in front of another.
