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. 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.






2. 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






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






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






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






6. Best at seeing fine details






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






8. Proposed the opponent color/process theory






9. 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






10. Asserts that perception and cognition are largely innate






11. 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.






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






13. Defined the Just Noticeable Difference






14. Is the tendency to complete incomplete figures






15. 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






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

17. How we organize or experience sensations






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






19. Located by the cornea






20. 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.






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






22. 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

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






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

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






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






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






28. Famous for the theory of color blindness






29. Failing to detect a present stimulus






30. humans best hear at






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






32. 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






33. 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.






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






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






36. Has monocular and binocular cues






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






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






39. Found that infants prefer relatively complex and sensational displays






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






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






42. Is the inability to recognize faces






43. Is composed of photons and waves measured by brightness and wavelengths






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






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






46. 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.






47. Is the result of regeneration of retinal pigment






48. Along the visual pathway is the...






49. 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.






50. The feeling that results from physical stimulation
