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






2. Is the result of regeneration of retinal pigment






3. The chemical that aids the receptor cells in transduction






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






5. 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






6. 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






7. 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.






8. 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.






9. 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






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






11. Best at seeing fine details






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






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






14. A theory for color vision. It suggests that two types of color sensitive cells exist: Cones that respond to blue-yellow colors and cones that respond to red-green. When one color of the cone is stimulated - the other is inhibited.






15. 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






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






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






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






19. Rightly stating that no stimulus exists






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






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






22. The physical intensity of light






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






24. Failing to detect a present stimulus






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






26. humans best hear at






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






28. 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.






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






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






31. Along the visual pathway is the...






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






33. 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






34. Correctly sensing a stimulus






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






36. How we organize or experience sensations






37. 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






38. Why do cones see better than rods?






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






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






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






42. Consists of the bony labyrinth - a hollow cavity in the temporal bone of the skull with a system of passages comprising two main functional parts: The cochlea - dedicated to hearing; converting sound pressure patterns from the outer ear into electroc






43. Is the inability to recognize faces






44. Is the tendency to complete incomplete figures






45. 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.






46. 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






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






48. Comes from the complexity of the sound wave






49. 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.






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