8. Suggests that there are three types of receptors in the retina: cones that respond to red - blue - or green






9. After images are perceived because of fatigued receptors. Because our eyes have a partially oppositional system for seeing colors - such as red-green or black-white - once on side is overstimulated and fatigued - it can no longer respond and is overs






10. Applies to all senses but only to a limited range of intensities. The law states that a stimulus needs to be increased by a constant fraction of its original value in order to be noticeably different

11. Curces are graphical representations of a subject'S sensitivity to a stimulus






12. It travels through the horizontal cells to the bipolar cells to the amacrine cells. Finally the information heads to the ganglion cells.






13. Revolves around perception and asserts that people tend to see the world as comprised of organized wholes. The world is understood through top-down processing.






14. The part of the world that triggers a particular neuron






15. The moon looks larger when we see it on the horizon than when we see it in the sky. This is because the horizon contains visual cues that make the moon seem more distant than the overhead sky.






16. Has been called the most important depth cue. Our eyes view objects from two slightly different angles - which allows us to create a 3-dimensional figure






17. Has been explained as the increasing ability of a child to make finer discriminations among stimuli.






18. Best at seeing fine details






19. Electrical impulses travel down these to the brain - where the information is understood






20. Is the tendency to make figures out of symmetrical images






21. Has monocular and binocular cues






22. Saying you detect a stimulus that is not there






23. Rods and cones on the retina that are responsible for sensory transduction.






24. The overarching Gestalt idea that experience will be organized as meaningful - symmetrical - and simple whenever possible.






25. Defined the Just Noticeable Difference

39. Or overlap of objects shows which objects are closer






40. 1. Reception 2. Sensory Transduction 3. Neural Pathways






41. A theory for color vision. It suggests that two types of color sensitive cells exist: Cones that respond to blue-yellow colors and cones that respond to red-green. When one color of the cone is stimulated - the other is inhibited.






42. The clear protective coating on the outside of the eye






43. The pace of vibrations or sound waves per second for a particular sound - determines pitch. Frequencies are measured in Hertz
