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






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






3. 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.






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






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






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






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






8. The feeling that results from physical stimulation






9. Comes from the complexity of the sound wave






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






11. 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.






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






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






14. Famous for the theory of color blindness






15. The physical intensity of light






16. 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






17. 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






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






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






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






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






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






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






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






25. Is the result of regeneration of retinal pigment






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






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






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


29. Along the visual pathway is the...






30. Failing to detect a present stimulus






31. Rightly stating that no stimulus exists






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






33. Proposed the perceptual development and optic array






34. Correctly sensing a stimulus






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






36. Why do cones see better than rods?






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






38. Asserts that perception and cognition are largely innate






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






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






41. Found that infants prefer relatively complex and sensational displays






42. Saying you detect a stimulus that is not there






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






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






45. 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






46. Has monocular and binocular cues






47. 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'






48. How we organize or experience sensations






49. 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






50. 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.
