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. 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.






2. Has monocular and binocular cues






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






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






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






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






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






8. humans best hear at






9. 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.






10. Along the visual pathway is the...






11. Best at seeing fine details






12. How we organize or experience sensations






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






14. 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.






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






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






17. The pace of vibrations or sound waves per second for a particular sound - determines pitch. Frequencies are measured in Hertz






18. 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






19. 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






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






21. 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






22. 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






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






24. 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






25. Correctly sensing a stimulus






26. Proposed the opponent color/process theory






27. Located by the cornea






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






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






30. 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.






31. Why do cones see better than rods?






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






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






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






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






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






37. Is the tendency to complete incomplete figures






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






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






40. Is the inability to recognize faces






41. 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'






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






43. Saying you detect a stimulus that is not there






44. Is the result of regeneration of retinal pigment






45. Asserts that perception and cognition are largely innate






46. 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.






47. Or overlap of objects shows which objects are closer






48. How movement is perceived though the displacement of objects over time - and how this motion takes place at seemingly different paces for nearby or faraway objects. Ships far away seem to move more slowly than ships moving at the same speed.






49. The feeling that results from physical stimulation






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