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






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






3. Found that infants prefer relatively complex and sensational displays






4. Is the inability to recognize faces






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. Is the tendency to complete incomplete figures






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






8. 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'






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






10. 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.






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






12. 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.






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






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






15. Famous for the theory of color blindness






16. Has monocular and binocular cues






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






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


19. The physical intensity of light






20. 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


21. 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






22. 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






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






24. 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






25. Comes from the complexity of the sound wave






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






27. 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






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






29. 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.






30. The chemical that aids the receptor cells in transduction






31. 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






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






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






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






35. Failing to detect a present stimulus






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






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






38. Is the result of regeneration of retinal pigment






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






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






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






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






43. 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






44. We see objects because of the light they reflect






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






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






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






48. Best at seeing fine details






49. 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.






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