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. Knowing that an elephant is large no matter how it might appear






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






3. How we organize or experience sensations






4. Best at seeing fine details






5. Comes from the complexity of the sound wave






6. The chemical that aids the receptor cells in transduction






7. We see objects because of the light they reflect






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






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

10. 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

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






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






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






14. 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






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






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






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






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






19. 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.






20. 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






21. 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.






22. Has monocular and binocular cues






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






24. 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.






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






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






27. Correctly sensing a stimulus






28. 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






29. 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






30. 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.






31. Why do cones see better than rods?






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






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






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






35. Or overlap of objects shows which objects are closer






36. After images are perceived because of fatigued receptors. Because our eyes have a partially oppositional system for seeing colors - such as red-green or black-white - once on side is overstimulated and fatigued - it can no longer respond and is overs






37. Famous for the theory of color blindness






38. How people perceive objects in the way that they are familiar with them - regardless of changes in the actual retinal image. A book - for example - is perceived as rectangular in shape no matter what angle it is seen from.






39. The feeling that results from physical stimulation






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






41. Proposed the opponent color/process theory






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






43. Located by the cornea






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






45. 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






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






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






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






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






50. 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
