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

2. 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.






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






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






5. 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.






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






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






8. Failing to detect a present stimulus






9. 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.






10. Located in the back of the eye - receives light images from the lens. It is composed of about 30 million photoreceptor cells and of other cell layers that process information






11. Proposed the perceptual development and optic array






12. The feeling that results from physical stimulation






13. Defined the Just Noticeable Difference






14. 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






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






16. 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.






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






18. 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






19. 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






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






21. 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.






22. 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.






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






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






25. We see objects because of the light they reflect






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






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






28. Saying you detect a stimulus that is not there






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






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






31. Has monocular and binocular cues






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






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






34. Or overlap of objects shows which objects are closer






35. Is the tendency to make figures out of symmetrical images






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






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






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






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






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






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






42. Comes from the complexity of the sound wave






43. Famous for the theory of color blindness






44. 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.






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






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






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






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






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