  • 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. Has monocular and binocular cues






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






4. humans best hear at






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






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






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






8. 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






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






10. How we organize or experience sensations






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






13. 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






14. Along the visual pathway is the...






15. 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






16. 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






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






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






19. Allows the eyes to see contrast and prevents repetitive information from being sent to the brain. Once the receptor cell is stimulated - the others nearby are inhibited.






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






21. Found that infants prefer relatively complex and sensational displays






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






23. Comes from the complexity of the sound wave






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






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

26. Best at seeing fine details






27. 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






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






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






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






31. 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.






32. Proposed the perceptual development and optic array






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






34. Located by the cornea






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






36. Correctly sensing a stimulus






37. Is the tendency to complete incomplete figures






38. We see objects because of the light they reflect






39. 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






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






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






42. 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.






43. Or overlap of objects shows which objects are closer






44. 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.






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






46. Famous for the theory of color blindness






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






48. 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.






49. 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.






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