Document Summary

It is not an all or none process. False alarm = detects stimulus that wasn"t there. Correct rejection = doesn"t detect stimulus since it wasn"t there. Ossicles: three tiny bones, hammer, anvil, and stirrup. Very little of what we call seeing occurs in the eyes, rather it is results from constructive processes that occur throughout much of the brain. Light first passes through the cornea thick, transparent outer layer of the eye. The cornea focuses incoming light in a process called refraction. Light rays are bent further in by the lens to form an image in the retina inner surface of the back of the eyeball. The pupil is a small opening in the front of the lens. To determine how much light enters an eye the pupil contracts or dilates. The iris determines the eyes color and pupil size.
