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






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






3. Best at seeing fine details






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






5. 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'






6. Has monocular and binocular cues






7. How we organize or experience sensations






8. Developed the visual cliff to study whether depth perception was innate






9. Comes from the complexity of the sound wave






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






11. humans best hear at






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






13. The chemical that aids the receptor cells in transduction






14. The eyes are connected to the cerebral cortex by...






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






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






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






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






19. 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.






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






21. The feeling that results from physical stimulation






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






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






24. Refers to the entire span that can be perceived or detected by the eye at a given moment.






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






26. 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.






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






28. 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

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






30. Famous for the theory of color blindness






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






32. 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






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






34. Proposed the tri-color theory - research shows that the opponent-process theory seems to be at work in the Lateral geniculate body - research shows that the tri-color theory seems to be at work in the Retina

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






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






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






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






43. 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.






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






45. Why do cones see better than rods?






46. 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.






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






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