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. We see objects because of the light they reflect






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






3. Along the visual pathway is the...






4. Proposed the perceptual development and optic array






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






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






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






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






9. Located by the cornea






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






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






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






13. 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






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






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






16. The feeling that results from physical stimulation






17. 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

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






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






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






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






25. 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






26. Found that infants prefer relatively complex and sensational displays






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






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






29. 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






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






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






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






33. 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






34. 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'






35. humans best hear at






36. 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.






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






38. 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.






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






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

41. 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.






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






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






44. How we organize or experience sensations






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






46. Comes from the complexity of the sound wave






47. Has monocular and binocular cues






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






49. Correctly sensing a stimulus






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