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. 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.






2. The physical intensity of light






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






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






5. Correctly sensing a stimulus






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






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






8. humans best hear at






9. Why do cones see better than rods?






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






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






12. 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.






13. Or overlap of objects shows which objects are closer






14. How we organize or experience sensations






15. 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






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






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






18. Saying you detect a stimulus that is not there






19. Best at seeing fine details






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






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






22. Is the tendency to complete incomplete figures






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






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






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






26. Famous for the theory of color blindness






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






28. 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






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






30. Found that infants prefer relatively complex and sensational displays






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






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






33. 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.






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






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






36. 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






37. 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.






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






39. 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






40. 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






41. Asserts that perception and cognition are largely innate






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






43. 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.






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






45. Applies to all senses but only to a limited range of intensities. The law states that a stimulus needs to be increased by a constant fraction of its original value in order to be noticeably different

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






47. 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






48. Proposed the perceptual development and optic array






49. Is the result of regeneration of retinal pigment






50. Rightly stating that no stimulus exists
