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






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






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






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






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






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






7. We see objects because of the light they reflect






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






9. 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






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






11. Has monocular and binocular cues






12. 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






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






14. 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






15. Best at seeing fine details






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






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

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






19. Or overlap of objects shows which objects are closer






20. The feeling that results from physical stimulation






21. Found that infants prefer relatively complex and sensational displays






22. 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.






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






24. 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.






25. Famous for the theory of color blindness






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






27. 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






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






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






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

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






33. Proposed the opponent color/process theory






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






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






36. Defined the Just Noticeable Difference






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






38. Is the result of regeneration of retinal pigment






39. Proposed the perceptual development and optic array






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






41. Allows the eyes to see contrast and prevents repetitive information from being sent to the brain. Once the receptor cell is stimulated - the others nearby are inhibited.






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






43. Comes from the complexity of the sound wave






44. humans best hear at






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






46. 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.






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






48. 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






49. 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.






50. How we organize or experience sensations
