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






2. 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






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






4. 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

5. 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.






6. 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.






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






8. 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






9. Saying you detect a stimulus that is not there






10. Found that infants prefer relatively complex and sensational displays






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






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






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






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






15. How we organize or experience sensations






16. Is the result of regeneration of retinal pigment






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






18. 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'






19. Best at seeing fine details






20. Proposed the opponent color/process theory






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






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






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






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






25. humans best hear at






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






27. 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






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






29. Comes from the complexity of the sound wave






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






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






32. Located by the cornea

34. 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






35. Why do cones see better than rods?






36. After the optic chasm - information travels to the...






37. 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.






38. 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.






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






40. Correctly sensing a stimulus






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






42. Asserts that perception and cognition are largely innate






43. 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.






44. Begins with the tympanic membrane (eardrum) which is stretch across the auditory canal. Behind this membrane are the Ossicles (3 small bones) - the last of which is the stapes. Sound vibrations bump against the tympanic membrane - causing the ossicl

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. 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






48. 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.






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






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