1. 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






2. After the optic chasm - information travels to the...






3. 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.






4. 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.






5. Knowing that an elephant is large no matter how it might appear






6. He tendency to group together items that are near each other






7. Proposed the opponent color/process theory






8. 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.






9. Rightly stating that no stimulus exists






10. The center of the retina; has the greatest visual acuity






11. We see objects because of the light they reflect






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






13. The optic nerve is made up of...






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






15. Found that infants prefer relatively complex and sensational displays






16. Can be perceived as two different things depending on how you look at them






17. 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






18. Is the minimum amount of stimuli that can be detected 50% of the time






19. Refers to the entire span that can be perceived or detected by the eye at a given moment.






20. Factors into why we see what we expect to see






21. Allow the cornea to bend (accommodate) in order to focus an image of the outside world onto the retina






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






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






24. Is the tendency to create a whole or detailed figure based on our expectations rather than what is seen






25. humans best hear at






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






27. Suggests that subjects detect stimuli not only because they can but also because they want to. TSD factors motivation into the picture.

28. Allows the eyes to see contrast and prevents repetitive information from being sent to the brain. Once the receptor cell is stimulated - the others nearby are inhibited.






29. Says that the strength of a stimulus must be significantly increased to produce a slight difference in sensation

30. Are concentrated in the center of the retina. They are sensitive to color and daylight vision.






31. Is the tendency to complete incomplete figures






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






33. Is the tendency to see what is easiest or logical to see






34. Discovered that cells in the visual cortex were so complex and specialized that they respond to certain types of stimuli. For example - some cells only respond to vertical lines - whereas some respond to only right angles.






35. Located by the cornea






36. Is composed of photons and waves measured by brightness and wavelengths






37. Failing to detect a present stimulus






38. 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

39. The physical intensity of light






40. Consists of one optic nerve connection each eye to the brain.






41. Or overlap of objects shows which objects are closer






42. Best at seeing fine details






43. Is the way that perceived color brightness changes with the level of illumination in the room. With lower levels of illumination - the extremes of the color spectrum (especially red) are seen as less bright






44. Is gained by features we are familiar with - such as two seemingly parallel lines that converge with distance






45. Proposed the perceptual development and optic array






46. Also known as just noticeable difference. The minimum difference that must occur between two stimuli - in order for them to be perceived as having different intensities.






47. Is knowing the color of an object even with tinted glasses on






48. Objects that have been drawn and can be perceived but are geometrically impossible






49. Also known as color - is the dominant wavelength of light






50. Is the inability to recognize faces
