Instructions:
  • Answer 50 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

1. The way that a single point of light viewed in darkness will appear to shake or move. the reason for this is the movement of our own eyes






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






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






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






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






6. 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.






7. Ambiguous figures - such as the Rubin vase. They can be perceived as two different things depending on which part you see as the figure and which part you see as the background.






8. We see objects because of the light they reflect






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






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






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






12. Failing to detect a present stimulus






13. The feeling that results from physical stimulation






14. Best at seeing fine details






15. Asserts that perception is the sum total of sensory input. The world is understood through bottom-up processing






16. All the things a person sees trains them to perceive






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






18. Are particularly sensitive to dim light and are used for night vision. They are also concentrated along the sides of the retina - making them extremely important for peripheral vision






19. Or overlap of objects shows which objects are closer






20. The tendency to perceive a smooth motion. This explains why motion is perceived when there is none - often by the use of flashing lights or rapidly shown still-fram pictures - such as in the perception of cartoons. This is apparent motion






21. Located in the back of the eye - receives light images from the lens. It is composed of about 30 million photoreceptor cells and of other cell layers that process information






22. The physical intensity of light






23. Where half of all fibers from the optic nerve of each eye cross over and join the optic nerve from the other eye. This insures input from each eye will be put together in a full picture in the brain.






24. A thick layer of glass above a surface that dropped off sharply. The glass provided solid - level ground doe subjects to move across in spite of the cliff below. Animals and babies were used as subjects and both groups avoided moving into the 'cliff'






25. Proposed the perceptual development and optic array






26. Proposed the opponent color/process theory






27. Is when two horizontal lines of equal length appear unequal because of two vertical lines that slant inward






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






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






30. 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.






31. Defined the Just Noticeable Difference






32. Refers to the relationship between the meaningful part of a picture and the background






33. Consists of the bony labyrinth - a hollow cavity in the temporal bone of the skull with a system of passages comprising two main functional parts: The cochlea - dedicated to hearing; converting sound pressure patterns from the outer ear into electroc






34. Is the result of regeneration of retinal pigment






35. 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.






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






37. 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






38. Famous for the theory of color blindness






39. 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






40. Found that infants prefer relatively complex and sensational displays






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






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

43. 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






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






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






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






47. Proposed the tri-color theory - research shows that the opponent-process theory seems to be at work in the Lateral geniculate body - research shows that the tri-color theory seems to be at work in the Retina






48. Gives us clues about how far away an object is if we know about how big the object should be






49. Why do cones see better than rods?






50. Has monocular and binocular cues
