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. The physical intensity of a sound wave largely determines loudness






2. 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.






3. Along the visual pathway is the...






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






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






6. Saying you detect a stimulus that is not there






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






8. 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.






9. Located by the cornea






10. Why do cones see better than rods?






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






12. humans best hear at






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






14. The physical intensity of light






15. Proposed the opponent color/process theory






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

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






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

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






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






21. 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.






22. 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






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. Best at seeing fine details






25. 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.






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






27. Failing to detect a present stimulus






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






29. Correctly sensing a stimulus






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






31. 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.






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






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






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






35. Defined the Just Noticeable Difference






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






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






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. How we organize or experience sensations






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






41. Has monocular and binocular cues






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






43. Rightly stating that no stimulus exists






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






45. 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






46. 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






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






48. Is the result of regeneration of retinal pigment






49. Found that infants prefer relatively complex and sensational displays






50. Or overlap of objects shows which objects are closer
