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. Located by the cornea






2. Suggests that there are three types of receptors in the retina: cones that respond to red - blue - or green






3. 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'






4. 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






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






6. Has monocular and binocular cues






7. 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.






8. 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.






9. Asserts that perception and cognition are largely innate






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






11. Is the tendency to complete incomplete figures






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


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






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






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






16. 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.






17. 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






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






19. Why do cones see better than rods?






20. 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.






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






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






23. Objects that have been drawn and can be perceived but are geometrically impossible






24. How we organize or experience sensations






25. 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






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






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






28. humans best hear at






29. Rightly stating that no stimulus exists






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






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






32. Famous for the theory of color blindness






33. 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.






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






35. 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






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






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






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






39. The feeling that results from physical stimulation






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






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






42. 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






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






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


45. Comes from the complexity of the sound wave






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






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






48. Failing to detect a present stimulus






49. Is the tendency to create a whole or detailed figure based on our expectations rather than what is seen






50. We see objects because of the light they reflect
