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.

1. 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






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






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






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






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






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






7. Best at seeing fine details






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






9. How we organize or experience sensations






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






11. humans best hear at






12. 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






13. Comes from the complexity of the sound wave






14. The chemical that aids the receptor cells in transduction






15. Famous for the theory of color blindness






16. Or overlap of objects shows which objects are closer






17. 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






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






19. 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.






20. The physical intensity of light






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






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






23. Correctly sensing a stimulus






24. 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






25. 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






26. 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






27. Is the inability to recognize faces






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






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

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

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






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






33. 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.






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






35. 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.






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






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






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






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






40. We see objects because of the light they reflect






41. 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






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






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






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






45. 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

46. Rightly stating that no stimulus exists






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






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






49. The feeling that results from physical stimulation






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