Document Summary

Textbook: psychology tenth edition in modules authored by david g. myers. Module 18: vision and perceptual organization and interpretation. Vision our eyes receive light energy and transduce (transform) it into neural messages that our brain then processes into what we consciously see. The eye: what we see as visible light is but a thin slice of the whole spectrum of electromagnetic energy, ranging from imperceptibly short gamma waves to the long wave of radio transmission. Other organisms are sensitive to differing portions of the spectrum. Bees cannot see what we perceive as red but can see ultraviolet light: two physical characteristics of light help determine our sensory experience of them. Light"s wavelength distance from one wave peak to the next determines hue. Intensity amount of energy in light waves (determined by a wave"s amplitude or height) influences brightness. Light enters the eye through the cornea (which protects the eye and bends light to provide focus).
