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. The clear protective coating on the outside of the eye






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






3. 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






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






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






6. Saying you detect a stimulus that is not there






7. 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






8. Consists of one optic nerve connection each eye to the brain.






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






10. Failing to detect a present stimulus






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






12. 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.






13. Proposed the opponent color/process theory






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






15. Defined the Just Noticeable Difference






16. The chemical that aids the receptor cells in transduction






17. Proposed the perceptual development and optic array






18. humans best hear at






19. Located by the cornea






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






21. 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.






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






23. 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.






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






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






26. Asserts that perception and cognition are largely innate






27. The feeling that results from physical stimulation






28. Has monocular and binocular cues






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






30. 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






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






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






33. Why do cones see better than rods?






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






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






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






37. The physical intensity of light






38. Is the tendency to complete incomplete figures






39. We see objects because of the light they reflect






40. Comes from the complexity of the sound wave






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






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






43. 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






44. How we organize or experience sensations






45. 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

46. 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.






47. 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'






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






49. 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






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