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. We see objects because of the light they reflect






2. Is the inability to recognize faces






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






4. humans best hear at






5. 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.






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






7. Along the visual pathway is the...






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






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






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






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






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






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






14. Why do cones see better than rods?






15. The part of the world that triggers a particular neuron






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






17. Has monocular and binocular cues






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






19. 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






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






21. 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






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






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






24. 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'






25. 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.






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






27. Is the result of regeneration of retinal pigment






28. 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.






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






30. 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.






31. It travels through the horizontal cells to the bipolar cells to the amacrine cells. Finally the information heads to the ganglion cells.






32. 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.






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






34. Proposed the perceptual development and optic array






35. 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






36. How we organize or experience sensations






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






38. Failing to detect a present stimulus






39. Correctly sensing a stimulus






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






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






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






43. Best at seeing fine details






44. 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.






45. The chemical that aids the receptor cells in transduction






46. 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.






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






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






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






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