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






2. humans best hear at






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






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






5. Is the inability to recognize faces






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. Failing to detect a present stimulus






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






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






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






11. Proposed the opponent color/process theory






12. Takes place when receptors for a particular sense detect a stimulus.






13. Defined the Just Noticeable Difference






14. 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






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






16. 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.






17. Located by the cornea






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






19. 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


20. The feeling that results from physical stimulation






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






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


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






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






25. 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.






26. 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.






27. We see objects because of the light they reflect






28. Comes from the complexity of the sound wave






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






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






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






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. 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.






34. 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






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






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






37. 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






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






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






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






41. How we organize or experience sensations






42. Is the result of regeneration of retinal pigment






43. The chemical that aids the receptor cells in transduction






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






45. 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.






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






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






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






49. Or overlap of objects shows which objects are closer






50. Is the tendency to complete incomplete figures
