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. Has monocular and binocular cues






2. 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.






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






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






5. Or overlap of objects shows which objects are closer






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






7. Is the tendency to complete incomplete figures






8. humans best hear at






9. Proposed the opponent color/process theory






10. The physical intensity of light






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






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






13. 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.






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






15. 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.






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






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






18. We see objects because of the light they reflect






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






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






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






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






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






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






25. Is the result of regeneration of retinal pigment






26. Is the inability to recognize faces






27. Found that infants prefer relatively complex and sensational displays






28. 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.






29. 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.






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






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






32. 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

33. Correctly sensing a stimulus






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






35. 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






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






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






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






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






40. 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






41. 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






42. 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






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






44. Proposed the perceptual development and optic array






45. Famous for the theory of color blindness






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






47. 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






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






49. How we organize or experience sensations






50. 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.
