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 composed of photons and waves measured by brightness and wavelengths






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






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






4. Along the visual pathway is the...






5. 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






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






7. Failing to detect a present stimulus






8. Is the result of regeneration of retinal pigment






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






10. Found that infants prefer relatively complex and sensational displays






11. 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






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






13. 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






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






15. 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.






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






17. 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.






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






19. 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






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






21. Famous for the theory of color blindness






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






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






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






25. The chemical that aids the receptor cells in transduction






26. 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.






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






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






29. Best at seeing fine details






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






31. 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






32. Or overlap of objects shows which objects are closer






33. Is the tendency to complete incomplete figures






34. Comes from the complexity of the sound wave






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






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






37. 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'






38. Defined the Just Noticeable Difference






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






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






41. Proposed the perceptual development and optic array






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

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. 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






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






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






47. 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.






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






49. Rightly stating that no stimulus exists






50. Located by the cornea
