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. Saying you detect a stimulus that is not there






2. Famous for the theory of color blindness






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






4. 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






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






6. Asserts that perception and cognition are largely innate






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






8. 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






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






10. Refers to how we see texture or fine detail differently from different distances






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






12. 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






13. Is the tendency to complete incomplete figures






14. Consists of the parts you see called the pinna and the auditory canal. Vibrations from sound move down this canal to the middle ear.






15. 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.






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






17. Failing to detect a present stimulus






18. Has monocular and binocular cues






19. Located by the cornea






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






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






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






23. 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






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






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






26. Defined the Just Noticeable Difference






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






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






29. The feeling that results from physical stimulation






30. How we organize or experience sensations






31. 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.






32. 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






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






34. Proposed the opponent color/process theory






35. We see objects because of the light they reflect






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






37. Is the result of regeneration of retinal pigment






38. Comes from the complexity of the sound wave






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






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






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






42. 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.






43. 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.






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






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






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






47. Rightly stating that no stimulus exists






48. 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.






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






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