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. Defined the Just Noticeable Difference






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






3. Has monocular and binocular cues






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






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. Correctly sensing a stimulus






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






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






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






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






11. Suggests that subjects detect stimuli not only because they can but also because they want to. TSD factors motivation into the picture.


12. 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.






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






14. Proposed the opponent color/process theory






15. 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.






16. 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'






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






18. 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.






19. Proposed the perceptual development and optic array






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






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






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






23. Why do cones see better than rods?






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






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






26. Best at seeing fine details






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






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






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


30. 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.






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






32. 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






33. The chemical that aids the receptor cells in transduction






34. Individuals are partly motivated by rewards and costs in detection. The interplay between response bias and stimulus intensity determines responses






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






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






37. 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.






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






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






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






41. Or overlap of objects shows which objects are closer






42. We see objects because of the light they reflect






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






44. 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






45. 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.






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






47. 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.






48. How we organize or experience sensations






49. Is the result of regeneration of retinal pigment






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