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. Defined the Just Noticeable Difference






2. 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






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. Where half of all fibers from the optic nerve of each eye cross over and join the optic nerve from the other eye. This insures input from each eye will be put together in a full picture in the brain.






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






6. 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.






7. Why do cones see better than rods?






8. How we organize or experience sensations






9. We see objects because of the light they reflect






10. 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.






11. Correctly sensing a stimulus






12. Located by the cornea






13. 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.






14. 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






15. The physical intensity of light






16. Is the tendency to complete incomplete figures






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






18. Comes from the complexity of the sound wave






19. 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






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






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






22. Famous for the theory of color blindness






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






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

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

26. 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






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






28. 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






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






30. humans best hear at






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






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






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






34. 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

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






36. 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.






37. Found that infants prefer relatively complex and sensational displays






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






39. 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






40. A thick layer of glass above a surface that dropped off sharply. The glass provided solid - level ground doe subjects to move across in spite of the cliff below. Animals and babies were used as subjects and both groups avoided moving into the 'cliff'






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






42. Asserts that perception and cognition are largely innate






43. The feeling that results from physical stimulation






44. Rightly stating that no stimulus exists






45. Saying you detect a stimulus that is not there






46. 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






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






48. Is the result of regeneration of retinal pigment






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






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