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. Proposed the opponent color/process theory






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






3. 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.






4. Defined the Just Noticeable Difference






5. 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.






6. The feeling that results from physical stimulation






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






8. Famous for the theory of color blindness






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






10. 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.






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






12. Best at seeing fine details






13. 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.






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






15. A thick layer of glass above a surface that dropped off sharply. The glass provided solid - level ground doe subjects to move across in spite of the cliff below. Animals and babies were used as subjects and both groups avoided moving into the 'cliff'






16. 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.






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






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






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






20. Is the result of regeneration of retinal pigment






21. 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.






22. Is the way that perceived color brightness changes with the level of illumination in the room. With lower levels of illumination - the extremes of the color spectrum (especially red) are seen as less bright






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






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






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






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






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






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






29. 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.






30. The physical intensity of light






31. 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






32. Has monocular and binocular cues






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






34. Or overlap of objects shows which objects are closer






35. 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.






36. 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.






37. We see objects because of the light they reflect






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






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






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






41. Why do cones see better than rods?






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






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






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. 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

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






47. Is the inability to recognize faces






48. Rightly stating that no stimulus exists






49. 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






50. Consists of the bony labyrinth - a hollow cavity in the temporal bone of the skull with a system of passages comprising two main functional parts: The cochlea - dedicated to hearing; converting sound pressure patterns from the outer ear into electroc
