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






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






3. Saying you detect a stimulus that is not there






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






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






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






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






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






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






10. 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






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






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






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






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






15. 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.






16. Rightly stating that no stimulus exists






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






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






19. 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.






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

21. 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






22. Located by the cornea






23. 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






24. 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.






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






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 inability to recognize faces






28. 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.






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






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






31. Defined the Just Noticeable Difference






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






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






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






35. Why do cones see better than rods?






36. The physical intensity of light






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






38. Has monocular and binocular cues






39. Is the tendency to complete incomplete figures






40. 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.






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






42. Correctly sensing a stimulus






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






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






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






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






47. 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






48. Proposed the perceptual development and optic array






49. Found that infants prefer relatively complex and sensational displays






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