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






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






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






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






7. 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.

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






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






12. The tendency to perceive a smooth motion. This explains why motion is perceived when there is none - often by the use of flashing lights or rapidly shown still-fram pictures - such as in the perception of cartoons. This is apparent motion






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

18. Located by the cornea






19. Is the tendency to complete incomplete figures

21. 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






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






23. 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.






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






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






26. 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.






27. 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






28. Proposed the opponent color/process theory






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






30. Rightly stating that no stimulus exists






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






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

34. Found that infants prefer relatively complex and sensational displays






35. Is the inability to recognize faces






36. 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

40. How we organize or experience sensations






41. 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.






42. Or overlap of objects shows which objects are closer
