Document Summary
Crossing of the senses (most common form of colored hearing) Eyes, ears, nose, skin and tongue are complex, miniaturized, living sense organs that automatically gather info about environment. Transduction- process in which a sense organ changes, or transforms, physical energy into electrical signals that become neutral impulses, which may be sent to the brain for processing continuous level of stimulation. Adaptation- the response of the sense organs as they are exposed to a. Perceptions; meaningful sensory experiences that result after the brain processes electrical signals that come from sense organs combines hundreds of sensations. Invisible (too short)-- gamma rays, x-rays, ultraviolet rays. Visible (just right)-- visible spectrum is a particular segment of electromagnetic energy that we can see because these waves are right length to stimulate receptors in the eye. Invisible (too long)-- radar, fm, tv, shortwave, am. 1st; gather and focus light into precise area in the back of eye.
