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. How we organize or experience sensations






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






3. Has monocular and binocular cues






4. The feeling that results from physical stimulation






5. 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.






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






7. 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






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






9. Is the result of regeneration of retinal pigment






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






11. 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.






12. Along the visual pathway is the...






13. Proposed the opponent color/process theory






14. 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.






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






16. 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.






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






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






19. Factors into why we see what we expect to see






20. 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.






21. Defined the Just Noticeable Difference






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






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






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






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






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






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






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






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






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






31. Involves both innate/sensory and is partially learned/conceptual






32. 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






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






34. Asserts that perception and cognition are largely innate






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






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






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






38. Consists of the bony labyrinth - a hollow cavity in the temporal bone of the skull with a system of passages comprising two main functional parts: The cochlea - dedicated to hearing; converting sound pressure patterns from the outer ear into electroc






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






40. Comes from the complexity of the sound wave






41. Why do cones see better than rods?






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






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






44. Is the inability to recognize faces






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






46. 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.






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






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






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. Famous for the theory of color blindness
