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






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






3. 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.






4. 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






5. Has monocular and binocular cues






6. 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






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






8. Rightly stating that no stimulus exists






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






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






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






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






13. The feeling that results from physical stimulation






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






15. 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.






16. Failing to detect a present stimulus






17. 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






18. 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






19. 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






20. Correctly sensing a stimulus






21. Or overlap of objects shows which objects are closer






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






23. Defined the Just Noticeable Difference






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






25. 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.






26. 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






27. Is the tendency to complete incomplete figures






28. Proposed the perceptual development and optic array






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






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






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






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






33. 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.






34. 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






35. 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.






36. Why do cones see better than rods?






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






38. Proposed the opponent color/process theory






39. 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.






40. Found that infants prefer relatively complex and sensational displays






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






42. 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.






43. 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






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






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






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






47. 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.






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






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






50. 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'
