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. 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






2. 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






3. Rightly stating that no stimulus exists






4. 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






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






6. The most famous of all visual illusions. Two horizontal lines of equal length appear unequal because of the orientation of the arrow marks at the end. Inward facing arrow marks make the line appear shorter than another line of the same length with ou






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






8. Found that infants prefer relatively complex and sensational displays






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






10. Proposed the opponent color/process theory






11. Is the result of regeneration of retinal pigment






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






13. The feeling that results from physical stimulation






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






15. Located by the cornea






16. Also known as just noticeable difference. The minimum difference that must occur between two stimuli - in order for them to be perceived as having different intensities.






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






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






19. 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'






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






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






22. 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






23. The physical intensity of light






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






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






26. Is the inability to recognize faces






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






28. Is the tendency to complete incomplete figures






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






30. The chemical that aids the receptor cells in transduction






31. 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.






32. Along the visual pathway is the...






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






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






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






36. 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.






37. Has monocular and binocular cues






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






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






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






41. Defined the Just Noticeable Difference






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






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






44. 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

Warning: Invalid argument supplied for foreach() in /var/www/html/basicversity.com/show_quiz.php on line 183


45. Or overlap of objects shows which objects are closer






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






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






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






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.
