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






2. 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






3. 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






4. Is the tendency to complete incomplete figures






5. 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

6. 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






7. Located by the cornea






8. The chemical that aids the receptor cells in transduction






9. 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.






10. We see objects because of the light they reflect






11. Or overlap of objects shows which objects are closer






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






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






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






15. Famous for the theory of color blindness






16. Is the result of regeneration of retinal pigment






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






18. Proposed the opponent color/process theory






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






20. Comes from the complexity of the sound wave






21. Found that infants prefer relatively complex and sensational displays






22. Refers to the entire span that can be perceived or detected by the eye at a given moment.






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






24. 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.






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






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






27. Along the visual pathway is the...






28. humans best hear at






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






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






31. 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






32. 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.






33. After the optic chasm - information travels to the...






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






35. 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.






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






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






38. Best at seeing fine details






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






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






41. Failing to detect a present stimulus






42. How we organize or experience sensations






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






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






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






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






47. 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.






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






49. 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






50. Is the inability to recognize faces
