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






2. Asserts that perception and cognition are largely innate






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






4. 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






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






6. 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.






7. We see objects because of the light they reflect






8. 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.






9. 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






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






11. Has monocular and binocular cues






12. Located by the cornea






13. The physical intensity of light






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






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






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






17. 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.






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






19. 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.






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






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






22. Is the inability to recognize faces






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






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






25. 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'






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






27. Failing to detect a present stimulus






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






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






30. 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.






31. Or overlap of objects shows which objects are closer






32. The chemical that aids the receptor cells in transduction






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. 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






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






36. Saying you detect a stimulus that is not there






37. Is the tendency to complete incomplete figures






38. 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.






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






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






41. Along the visual pathway is the...






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






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






44. 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.






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






46. 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






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

48. 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






49. How we organize or experience sensations






50. Comes from the complexity of the sound wave
