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. Or overlap of objects shows which objects are closer






2. 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.






3. Best at seeing fine details






4. Begins with the tympanic membrane (eardrum) which is stretch across the auditory canal. Behind this membrane are the Ossicles (3 small bones) - the last of which is the stapes. Sound vibrations bump against the tympanic membrane - causing the ossicl






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






6. 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






7. Individuals are partly motivated by rewards and costs in detection. The interplay between response bias and stimulus intensity determines responses






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






9. Developed the visual cliff to study whether depth perception was innate






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






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






12. Defined the Just Noticeable Difference






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






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






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






16. The physical intensity of light






17. 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






18. 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






19. Proposed the opponent color/process theory






20. Has monocular and binocular cues






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






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






23. 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'






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






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






26. 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






27. Proposed the perceptual development and optic array






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

29. Comes from the complexity of the sound wave






30. Is the tendency to complete incomplete figures






31. 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.






32. 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.






33. The most famous of all visual illusions. Two horizontal lines of equal length appear unequal because of the orientation of the arrow marks at the end. Inward facing arrow marks make the line appear shorter than another line of the same length with ou






34. The eyes are connected to the cerebral cortex by...






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






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






37. 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.






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






39. Is the inability to recognize faces






40. Why do cones see better than rods?






41. How movement is perceived though the displacement of objects over time - and how this motion takes place at seemingly different paces for nearby or faraway objects. Ships far away seem to move more slowly than ships moving at the same speed.






42. 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.






43. 1. closure 2. Proximity 3. Continuation or good continuation 4. Symmetry 5. Constancy 6. Minimum principle






44. Found that infants prefer relatively complex and sensational displays






45. How we organize or experience sensations






46. Is the upper limit above which the stimuli can no longer be perceived. -The highest pitch sound a human could hear






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






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






49. Involves both innate/sensory and is partially learned/conceptual






50. We see objects because of the light they reflect
