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 the tendency to complete incomplete figures






2. 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'






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






4. Located by the cornea






5. 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






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

7. 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






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






9. The physical intensity of light






10. 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.






11. Asserts that perception and cognition are largely innate






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






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






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






15. Why do cones see better than rods?






16. We see objects because of the light they reflect






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






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






19. Saying you detect a stimulus that is not there






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






21. Is the result of regeneration of retinal pigment






22. Is the inability to recognize faces






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






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






25. Best at seeing fine details






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






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






28. 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






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

30. Defined the Just Noticeable Difference






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






32. How we organize or experience sensations






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






34. Along the visual pathway is the...






35. Comes from the complexity of the sound wave






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






37. Correctly sensing a stimulus






38. 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.






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






40. Rightly stating that no stimulus exists






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






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






43. 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






44. 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






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






46. humans best hear at






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






49. 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.






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