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. Best at seeing fine details






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






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






4. Located by the cornea






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






6. 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






7. Saying you detect a stimulus that is not there






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






9. 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






10. The feeling that results from physical stimulation






11. Is the inability to recognize faces






12. 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






13. Says that the strength of a stimulus must be significantly increased to produce a slight difference in sensation

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






15. The chemical that aids the receptor cells in transduction






16. 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.






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






18. Also known as color - is the dominant wavelength of light






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






20. Correctly sensing a stimulus






21. Rightly stating that no stimulus exists






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

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






24. Why do cones see better than rods?






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






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






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






28. 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.






29. 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






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






31. 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.






32. Found that infants prefer relatively complex and sensational displays






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






34. Along the visual pathway is the...






35. 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.






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






37. Is the result of regeneration of retinal pigment






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






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






40. 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






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






42. Has monocular and binocular cues






43. 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.






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






45. Comes from the complexity of the sound wave






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






47. 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






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






49. 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






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