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. Correctly sensing a stimulus






2. 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.






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






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






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






6. Failing to detect a present stimulus






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






8. Why do cones see better than rods?






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






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






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






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






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






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






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






16. 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






17. 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.






18. The chemical that aids the receptor cells in transduction






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






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






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






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






23. Rightly stating that no stimulus exists






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

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






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






27. 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






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






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






30. 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.






31. 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






32. Located by the cornea






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






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






35. Saying you detect a stimulus that is not there






36. Best at seeing fine details






37. 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






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. The part of the world that triggers a particular neuron






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






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






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






43. Found that infants prefer relatively complex and sensational displays






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






45. 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.






46. We see objects because of the light they reflect






47. 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






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






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






50. Proposed the opponent color/process theory
