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 knowing the color of an object even with tinted glasses on






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






3. 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






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






5. humans best hear at






6. Rightly stating that no stimulus exists






7. Electrical impulses travel down these to the brain - where the information is understood






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






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






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






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






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






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






14. Is the inability to recognize faces






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






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






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






18. 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.






19. The physical intensity of light






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






21. 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.






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






23. 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.






24. 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






25. The chemical that aids the receptor cells in transduction






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






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






28. 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


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






30. Along the visual pathway is the...






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






32. Has monocular and binocular cues






33. 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.






34. The feeling that results from physical stimulation






35. 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.






36. Is the tendency to complete incomplete figures






37. Is the result of regeneration of retinal pigment






38. How we organize or experience sensations






39. Famous for the theory of color blindness






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






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






42. 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






43. Saying you detect a stimulus that is not there






44. 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.






45. How people perceive objects in the way that they are familiar with them - regardless of changes in the actual retinal image. A book - for example - is perceived as rectangular in shape no matter what angle it is seen from.






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






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






48. Located by the cornea






49. Found that infants prefer relatively complex and sensational displays






50. Proposed the perceptual development and optic array
