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. 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.






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






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






4. Found that infants prefer relatively complex and sensational displays






5. 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






6. 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.






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






8. Defined the Just Noticeable Difference






9. 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.






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






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






12. We see objects because of the light they reflect






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






14. 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.






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






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






17. 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.






18. Best at seeing fine details






19. humans best hear at






20. Comes from the complexity of the sound wave






21. 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






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. 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






24. 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.






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






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






27. 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






28. 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.






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






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






31. Why do cones see better than rods?






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






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






34. 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






35. 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.






36. 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.






37. Or overlap of objects shows which objects are closer






38. Asserts that perception and cognition are largely innate






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






40. The feeling that results from physical stimulation






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






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

43. 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






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






45. 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






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






47. Proposed the opponent color/process theory






48. The chemical that aids the receptor cells in transduction






49. Located by the cornea






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