Subjects : gre, psychology
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. Comes from the complexity of the sound wave






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






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






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






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






7. 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






8. 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






9. 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.






10. 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.






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






12. How we organize or experience sensations






13. Ambiguous figures - such as the Rubin vase. They can be perceived as two different things depending on which part you see as the figure and which part you see as the background.






14. 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






15. Found that infants prefer relatively complex and sensational displays






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






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






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






19. The feeling that results from physical stimulation






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






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






22. Rightly stating that no stimulus exists






23. 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






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






25. Failing to detect a present stimulus






26. Is the tendency to complete incomplete figures






27. 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.






28. 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.






29. humans best hear at






30. 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






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






32. Are concentrated in the center of the retina. They are sensitive to color and daylight vision.






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






34. Correctly sensing a stimulus






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

36. Defined the Just Noticeable Difference






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






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






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






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






41. Has monocular and binocular cues






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






43. Or overlap of objects shows which objects are closer






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






45. 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

46. Asserts that perception and cognition are largely innate






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






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






49. Proposed the opponent color/process theory






50. Proposed the perceptual development and optic array
