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






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






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






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






5. 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'






6. 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.






7. Also known as color - is the dominant wavelength of light






8. 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.






9. The overarching Gestalt idea that experience will be organized as meaningful - symmetrical - and simple whenever possible.






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






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






12. 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






13. Why do cones see better than rods?






14. Along the visual pathway is the...






15. 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.






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






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






18. 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






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






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






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






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






23. Is the tendency to complete incomplete figures






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






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






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

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






28. The physical intensity of light






29. The feeling that results from physical stimulation






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






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






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

33. humans best hear at






34. 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

35. Asserts that perception and cognition are largely innate






36. We see objects because of the light they reflect






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






38. Proposed the opponent color/process theory






39. 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.






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






41. 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.






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






43. 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






44. Comes from the complexity of the sound wave






45. Rightly stating that no stimulus exists






46. Or overlap of objects shows which objects are closer






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






48. Is the tendency to make figures out of symmetrical images






49. 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.






50. Is the result of regeneration of retinal pigment
