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. Comes from the complexity of the sound wave






2. The eyes are connected to the cerebral cortex by...






3. Rightly stating that no stimulus exists






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






5. humans best hear at






6. Asserts that perception and cognition are largely innate






7. 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.






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






9. 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






10. 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






11. Are particularly sensitive to dim light and are used for night vision. They are also concentrated along the sides of the retina - making them extremely important for peripheral vision






12. Refers to how we see texture or fine detail differently from different distances






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






14. Why do cones see better than rods?






15. Is the result of regeneration of retinal pigment






16. 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






17. 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.






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






19. The physical intensity of light






20. 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






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. Along the visual pathway is the...






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






24. Is the tendency to complete incomplete figures






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






26. Is gained by features we are familiar with - such as two seemingly parallel lines that converge with distance






27. Has monocular and binocular cues






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






29. Defined the Just Noticeable Difference






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






31. Correctly sensing a stimulus






32. 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.






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






34. 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.






35. 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.






36. Best at seeing fine details






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






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






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






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






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






42. 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


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






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






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






46. Is the inability to recognize faces






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






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






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






50. Proposed the opponent color/process theory
