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. Rightly stating that no stimulus exists






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






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






4. Failing to detect a present stimulus






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






6. 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.






7. Best at seeing fine details






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






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






10. The physical intensity of light






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






13. Asserts that perception and cognition are largely innate






14. Comes from the complexity of the sound wave






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






16. Why do cones see better than rods?






17. Famous for the theory of color blindness






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






19. Defined the Just Noticeable Difference






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






21. 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






22. Has monocular and binocular cues






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






24. We see objects because of the light they reflect






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






26. Is the tendency to see what is easiest or logical to see






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






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






29. Found that infants prefer relatively complex and sensational displays






30. 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






31. How we organize or experience sensations






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






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






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






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






36. Proposed the opponent color/process theory






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






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






40. 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.






41. Along the visual pathway is the...






42. Begins with the tympanic membrane (eardrum) which is stretch across the auditory canal. Behind this membrane are the Ossicles (3 small bones) - the last of which is the stapes. Sound vibrations bump against the tympanic membrane - causing the ossicl






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






44. Or overlap of objects shows which objects are closer






45. 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.






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






47. 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






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






49. 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'






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