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. We see objects because of the light they reflect






2. Correctly sensing a stimulus






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






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






5. How we organize or experience sensations






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






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






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






10. Proposed the perceptual development and optic array






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






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






13. 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.






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






15. 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






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

17. Is the tendency to complete incomplete figures






18. 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.






19. The physical intensity of light






20. Along the visual pathway is the...






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






22. Located by the cornea






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






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






26. Suggests that there are three types of receptors in the retina: cones that respond to red - blue - or green






27. 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.






28. Asserts that perception and cognition are largely innate






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






30. Is the inability to recognize faces






31. 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.






32. 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.






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






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. Best at seeing fine details






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






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






38. 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






39. Knowing that an elephant is large no matter how it might appear






40. 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

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






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






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

44. 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






45. Proposed the opponent color/process theory






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






47. 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






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






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






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