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 optic nerve is made up of...






2. Correctly sensing a stimulus






3. Is knowing the color of an object even with tinted glasses on






4. 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






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






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






7. The feeling that results from physical stimulation






8. Is the inability to recognize faces






9. 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.






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






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






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






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






15. Defined the Just Noticeable Difference






16. Failing to detect a present stimulus






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






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






19. 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.






20. 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'






21. Located by the cornea






22. 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.






23. Suggests that there are three types of receptors in the retina: cones that respond to red - blue - or green






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






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






26. 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.






27. 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






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






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






30. Saying you detect a stimulus that is not there






31. Asserts that perception and cognition are largely innate






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






33. Famous for the theory of color blindness






34. 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






35. Curces are graphical representations of a subject'S sensitivity to a stimulus






36. Found that infants prefer relatively complex and sensational displays






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






38. 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.






39. Or overlap of objects shows which objects are closer






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






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






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






43. 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.






44. 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.






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






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






47. 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






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


49. humans best hear at






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