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






2. humans best hear at






3. Is the inability to recognize faces






4. Best at seeing fine details






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






6. 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

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






8. Proposed the opponent color/process theory






9. Or overlap of objects shows which objects are closer






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






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






12. 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






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






14. 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.






15. Failing to detect a present stimulus






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






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






18. 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






19. Has monocular and binocular cues






20. Correctly sensing a stimulus






21. 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






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






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






24. Rightly stating that no stimulus exists






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






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






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






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






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






30. Is the tendency to complete incomplete figures






31. Found that infants prefer relatively complex and sensational displays






32. 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.






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






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






35. 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






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






37. 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






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






39. 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.






40. Defined the Just Noticeable Difference






41. 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.






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






43. Why do cones see better than rods?






44. How we organize or experience sensations






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






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






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






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






49. Is gained by features we are familiar with - such as two seemingly parallel lines that converge with distance






50. Asserts that perception and cognition are largely innate
