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 the result of regeneration of retinal pigment






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






3. Correctly sensing a stimulus






4. 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






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






6. The chemical that aids the receptor cells in transduction






7. 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






8. 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.






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






10. 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






11. 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






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






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






14. Or overlap of objects shows which objects are closer






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






16. Is the inability to recognize faces






17. Is the tendency to complete incomplete figures






18. Has been explained as the increasing ability of a child to make finer discriminations among stimuli.






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






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






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






22. Why do cones see better than rods?






23. humans best hear at






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






25. Located by the cornea






26. 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






27. Defined the Just Noticeable Difference






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






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






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






31. Saying you detect a stimulus that is not there






32. 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.






33. How we organize or experience sensations






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






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. 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






37. Failing to detect a present stimulus






38. 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






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






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






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






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






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






44. Proposed the perceptual development and optic array






45. The physical intensity of light






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






47. Individuals are partly motivated by rewards and costs in detection. The interplay between response bias and stimulus intensity determines responses






48. Found that infants prefer relatively complex and sensational displays






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






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