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.

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






2. Is the inability to recognize faces






3. 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.






4. Has monocular and binocular cues






5. 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






6. Or overlap of objects shows which objects are closer






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






8. The physical intensity of light






9. Is the result of regeneration of retinal pigment






10. 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






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






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






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






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






15. The feeling that results from physical stimulation






16. 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






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






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






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. humans best hear at






21. Correctly sensing a stimulus






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






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

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






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






26. Defined the Just Noticeable Difference






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






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






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






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






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






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






33. Rightly stating that no stimulus exists






34. 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.






35. 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






36. Famous for the theory of color blindness






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






38. Failing to detect a present stimulus






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






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






41. 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.






42. Involves both innate/sensory and is partially learned/conceptual






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






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






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






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

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






48. 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.






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






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