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






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






3. Is the inability to recognize faces






4. Along the visual pathway is the...






5. 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.






6. Asserts that perception and cognition are largely innate






7. Rightly stating that no stimulus exists






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






9. The physical intensity of light






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






11. 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

12. 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






13. humans best hear at






14. Best at seeing fine details






15. Defined the Just Noticeable Difference






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






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






18. Famous for the theory of color blindness






19. The chemical that aids the receptor cells in transduction






20. 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.






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






22. Saying you detect a stimulus that is not there






23. 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






24. Found that infants prefer relatively complex and sensational displays






25. 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.






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






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






28. 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.






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






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






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






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






33. 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






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






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






36. How we organize or experience sensations






37. Why do cones see better than rods?






38. Proposed the perceptual development and optic array






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






40. 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.






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

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






43. Comes from the complexity of the sound wave






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. Factors into why we see what we expect to see






46. 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






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






48. Has monocular and binocular cues






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






50. 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.
