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. Located by the cornea






2. Correctly sensing a stimulus






3. 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






4. Says that the strength of a stimulus must be significantly increased to produce a slight difference in sensation

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






6. Best at seeing fine details






7. 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






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






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






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






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






12. Saying you detect a stimulus that is not there






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






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






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

17. 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.






18. Or overlap of objects shows which objects are closer






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






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






21. 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.






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






23. Gives us clues about how far away an object is if we know about how big the object should be






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






25. humans best hear at






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






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






28. 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






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






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






31. 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.






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






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






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






35. 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






36. Has monocular and binocular cues






37. 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.






38. Why do cones see better than rods?






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






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






41. 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.






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






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






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






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






46. Famous for the theory of color blindness






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






48. 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'






49. Is the tendency to complete incomplete figures






50. 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.
