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






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






3. Located by the cornea






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






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






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






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






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






9. Along the visual pathway is the...






10. 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.






11. 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.






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






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






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






15. 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'






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






17. 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






18. Allows the eyes to see contrast and prevents repetitive information from being sent to the brain. Once the receptor cell is stimulated - the others nearby are inhibited.






19. The physical intensity of light






20. Defined the Just Noticeable Difference






21. Comes from the complexity of the sound wave






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






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






24. 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






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






26. Why do cones see better than rods?






27. humans best hear at






28. 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






29. Asserts that perception and cognition are largely innate






30. 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


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






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






33. Failing to detect a present stimulus






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






35. Is the result of regeneration of retinal pigment






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






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






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






40. Best at seeing fine details






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






42. Is the inability to recognize faces






43. 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






44. Proposed the opponent color/process theory






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






46. Found that infants prefer relatively complex and sensational displays






47. Rightly stating that no stimulus exists






48. Has monocular and binocular cues






49. 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






50. 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.
