Document Summary

What is perception: the process by which agents interpret and organize sensation to produce a meaningful experience of the world, from a cognitive science perspective, it means turning information from one form into meaningful representation. Rays of light emanating from the eye in combination with light in the world allows us to see. Visual perception is accomplished by rays of light reflected from the objects into the eyes. Human eye: light is reflected into the eye and focused on the retina, light stimulates the rod and cone receptors, transduction of light into electricity. Rods and cones on retina: the image is severely distorted and inverted, rod: the most light sensitive photoreceptive cells in the retina (night vision): Information is received by a convergence or pooling from many rods cells resulting in a loss of visual acuity; Convergence of information makes peripheral vison sensitive to movement (seeing something in the corner of your eye).
