If the stimulus doesn"t change, you notice it less and less: occurs with all five senses. Transduction transforming one form of energy to another: wave length, short wavelength = high frequency (bluish color, great amplitude (bright colors, small amplitude (dull colors) The eye: normal vision occurs when light is focused directly on the retina rather than in front or behind it, nearsightedness: visual image is focused in front of the retina, pupil lets light into the eyes. Farsightedness: visual image is focused behind the retina: ambient light, medically induced, adrenaline (fight or flight, general indication of interest in something, cornea clear outer coating, protective of the eye, responsible for some focusing of light.
