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






2. The chemical that aids the receptor cells in transduction






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






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






5. Proposed the opponent color/process theory






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






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






8. Saying you detect a stimulus that is not there






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

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






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






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






13. 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.






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






15. 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






16. Famous for the theory of color blindness






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






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

19. Why do cones see better than rods?






20. 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.






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






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






23. Is the inability to recognize faces






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






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






26. 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






27. 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.






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






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






30. 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.






31. 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






32. The feeling that results from physical stimulation






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






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






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






36. 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.






37. Is the tendency to complete incomplete figures






38. 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.






39. Has monocular and binocular cues






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






41. Ambiguous figures - such as the Rubin vase. They can be perceived as two different things depending on which part you see as the figure and which part you see as the background.






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






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






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






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






46. Is the result of regeneration of retinal pigment






47. Proposed the perceptual development and optic array






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






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






50. 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.
