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. Comes from the complexity of the sound wave






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


3. 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.






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






5. Failing to detect a present stimulus






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






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






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






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






10. 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.






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






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






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






14. 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.






15. Best at seeing fine details






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






17. 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






18. Saying you detect a stimulus that is not there






19. 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






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






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






22. 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






23. How people perceive objects in the way that they are familiar with them - regardless of changes in the actual retinal image. A book - for example - is perceived as rectangular in shape no matter what angle it is seen from.






24. 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






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






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






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






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






29. Or overlap of objects shows which objects are closer






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






31. Located by the cornea






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






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






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






35. 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.






36. 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.






37. 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.






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






39. Has been explained as the increasing ability of a child to make finer discriminations among stimuli.






40. Asserts that perception and cognition are largely innate






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






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






43. Famous for the theory of color blindness






44. 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.






45. Is the result of regeneration of retinal pigment






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






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






48. Proposed the opponent color/process theory






49. Correctly sensing a stimulus






50. Is the inability to recognize faces
