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. Famous for the theory of color blindness






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






3. Is the inability to recognize faces






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






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






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






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






8. 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.






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. Comes from the complexity of the sound wave






11. We see objects because of the light they reflect






12. Located by the cornea






13. 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






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

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






16. 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






17. Why do cones see better than rods?






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






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






20. 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






21. The physical intensity of light






22. 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






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






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






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






26. 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.






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






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






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






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






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






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






33. 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.






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






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






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






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






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






39. Defined the Just Noticeable Difference






40. 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.






41. How we organize or experience sensations






42. The pace of vibrations or sound waves per second for a particular sound - determines pitch. Frequencies are measured in Hertz






43. Proposed the opponent color/process theory






44. humans best hear at






45. Correctly sensing a stimulus






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






47. 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.






48. 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






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






50. 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.
