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. 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






2. 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






3. Found that infants prefer relatively complex and sensational displays






4. 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.






5. 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.






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






7. 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.






8. The way that a single point of light viewed in darkness will appear to shake or move. the reason for this is the movement of our own eyes






9. Is the result of regeneration of retinal pigment






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






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






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






13. The chemical that aids the receptor cells in transduction






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. We see objects because of the light they reflect






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






17. Defined the Just Noticeable Difference






18. 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






19. 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






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






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






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






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






24. Comes from the complexity of the sound wave






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






26. 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.






27. 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






28. 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.






29. Failing to detect a present stimulus






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






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






32. 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






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






34. humans best hear at






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






36. The feeling that results from physical stimulation






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






38. Has monocular and binocular cues






39. Best at seeing fine details






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






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






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






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






44. After images are perceived because of fatigued receptors. Because our eyes have a partially oppositional system for seeing colors - such as red-green or black-white - once on side is overstimulated and fatigued - it can no longer respond and is overs






45. Or overlap of objects shows which objects are closer






46. Famous for the theory of color blindness






47. 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.






48. Correctly sensing a stimulus






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






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