Document Summary
Psych: a typical brain cell responds to only a small area of the total field of vision. In this example, the cell responds to stimuli that fall above and left of the center of vision: the bar graph illustrates how a brain cell may act as a feature detector. Notice how the cell primarily responds to one type of stimulus. Blindsight (variant of visual agnosia): preserved superior colliculus. Trichromatic theory color vision theory that states we have three cone types: blue, green, red other colors produced by a combination of these: wavelength sensitivity would suggest more like a blue, green, yellow, or blue, blue-green, yellow-green. : visual sensation that remains after stimulus is removed (seeing a flashbulb. Simultaneous color contrast changes in perceived hue that occur when a colored stimulus is displayed on backgrounds of various colors. : inability to perceive colors; lacks cones or has malfunctioning cones: total color blindness is rare, color weakness.
