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






3. Found that infants prefer relatively complex and sensational displays






4. We see objects because of the light they reflect






5. Along the visual pathway is the...






6. 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.






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






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






9. 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






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






11. Located in the back of the eye - receives light images from the lens. It is composed of about 30 million photoreceptor cells and of other cell layers that process information






12. 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






13. Is the inability to recognize faces






14. Defined the Just Noticeable Difference






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






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






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






18. The chemical that aids the receptor cells in transduction






19. Or overlap of objects shows which objects are closer






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






21. Comes from the complexity of the sound wave






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






23. 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






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






25. The physical intensity of light






26. How we organize or experience sensations






27. humans best hear at






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






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






30. Proposed the opponent color/process theory






31. Famous for the theory of color blindness






32. 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


33. Is the result of regeneration of retinal pigment






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






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






37. 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.






38. 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






39. 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






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






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






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






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






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






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






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


47. 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.






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


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






50. Best at seeing fine details
