  • 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. How we organize or experience sensations






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






3. 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






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






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






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






7. 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

8. Is the result of regeneration of retinal pigment






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






10. 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






11. 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.






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






13. 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






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






15. Or overlap of objects shows which objects are closer






16. 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.






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






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






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 eyes are connected to the cerebral cortex by...






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






22. 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






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






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






25. Famous for the theory of color blindness






26. The physical intensity of a sound wave largely determines loudness






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






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






29. The feeling that results from physical stimulation






30. Why do cones see better than rods?






31. 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






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






33. We see objects because of the light they reflect






34. 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.






35. Is the tendency to complete incomplete figures






36. Saying you detect a stimulus that is not there






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






38. 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.






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






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






41. 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.






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






43. Proposed the perceptual development and optic array






44. Rightly stating that no stimulus exists






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






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






47. 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






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






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






50. Defined the Just Noticeable Difference
