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. Located by the cornea






2. Famous for the theory of color blindness






3. Is the result of regeneration of retinal pigment






4. We see objects because of the light they reflect






5. The physical intensity of light






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






7. 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






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. 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.






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






11. Best at seeing fine details






12. Rightly stating that no stimulus exists






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






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






15. 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.






16. Or overlap of objects shows which objects are closer






17. 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






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

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






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






21. Has monocular and binocular cues






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






23. Why do cones see better than rods?






24. humans best hear at






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






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






27. Is the inability to recognize faces






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






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






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






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






33. 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






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






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






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






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






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






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






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

41. Found that infants prefer relatively complex and sensational displays






42. Asserts that perception and cognition are largely innate






43. A thick layer of glass above a surface that dropped off sharply. The glass provided solid - level ground doe subjects to move across in spite of the cliff below. Animals and babies were used as subjects and both groups avoided moving into the 'cliff'






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






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






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






47. The feeling that results from physical stimulation






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






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






50. 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
