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






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






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






4. 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.






5. 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






6. 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






7. 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.






8. humans best hear at






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






10. Is the tendency to complete incomplete figures






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






12. 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






13. Why do cones see better than rods?






14. Failing to detect a present stimulus






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






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






17. Found that infants prefer relatively complex and sensational displays






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






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






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






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






22. 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.






23. 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






24. 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






25. Or overlap of objects shows which objects are closer






26. The most famous of all visual illusions. Two horizontal lines of equal length appear unequal because of the orientation of the arrow marks at the end. Inward facing arrow marks make the line appear shorter than another line of the same length with ou






27. 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.






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






29. Is the result of regeneration of retinal pigment






30. Has monocular and binocular cues






31. Correctly sensing a stimulus






32. Best at seeing fine details






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






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






35. Defined the Just Noticeable Difference






36. 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.






37. 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






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






39. Proposed the perceptual development and optic array






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






41. How we organize or experience sensations






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






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






44. 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






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






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






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. Located by the cornea






49. Saying you detect a stimulus that is not there






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