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






2. 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






3. Famous for the theory of color blindness






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






5. Is the inability to recognize faces






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






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






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






9. 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






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






11. Is the tendency to complete incomplete figures






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






13. Saying you detect a stimulus that is not there






14. The chemical that aids the receptor cells in transduction






15. 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






16. Asserts that perception and cognition are largely innate






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






18. Best at seeing fine details






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






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






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






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






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






24. The physical intensity of light






25. 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.






26. 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






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






28. Individuals are partly motivated by rewards and costs in detection. The interplay between response bias and stimulus intensity determines responses






29. 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'






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






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






32. 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.






33. How we organize or experience sensations






34. 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






35. Rightly stating that no stimulus exists






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






37. Or overlap of objects shows which objects are closer






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






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






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






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






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






43. 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.






44. 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.






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






46. The overarching Gestalt idea that experience will be organized as meaningful - symmetrical - and simple whenever possible.






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

48. 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.






49. Why do cones see better than rods?






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