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. The clear protective coating on the outside of the eye






2. Along the visual pathway is the...






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






4. Best at seeing fine details






5. Why do cones see better than rods?






6. 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






7. We see objects because of the light they reflect






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






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






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






11. 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






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






13. 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






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






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






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






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






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






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






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






21. Comes from the complexity of the sound wave






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






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






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






25. Proposed the perceptual development and optic array






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






27. 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.






28. Is the inability to recognize faces






29. Famous for the theory of color blindness






30. Rightly stating that no stimulus exists






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






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






33. 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.






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






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






36. The physical intensity of light






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






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






39. 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.






40. 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






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






42. 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.






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






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






45. 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.






46. 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






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






48. 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.






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






50. 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
