GRE Psychology: Perception Sensation

Subjects : gre, psychology
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.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. 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.






2. The chemical that aids the receptor cells in transduction






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






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






5. Rightly stating that no stimulus exists






6. 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






7. 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.






8. Is the inability to recognize faces






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. How people perceive objects in the way that they are familiar with them - regardless of changes in the actual retinal image. A book - for example - is perceived as rectangular in shape no matter what angle it is seen from.






11. Comes from the complexity of the sound wave






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






13. Defined the Just Noticeable Difference






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






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






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






17. 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.






18. Saying you detect a stimulus that is not there






19. Famous for the theory of color blindness






20. Asserts that perception and cognition are largely innate






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






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






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






24. 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.






25. 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






26. The physical intensity of a sound wave largely determines loudness






27. The feeling that results from physical stimulation






28. 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






29. Proposed the opponent color/process theory






30. Found that infants prefer relatively complex and sensational displays






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






32. Along the visual pathway is the...






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






34. Is the result of regeneration of retinal pigment






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






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






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






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






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

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






41. Failing to detect a present stimulus






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






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






44. 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.






45. We see objects because of the light they reflect






46. Or overlap of objects shows which objects are closer






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






48. 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






49. Why do cones see better than rods?






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