1. Located by the cornea






2. Curces are graphical representations of a subject'S sensitivity to a stimulus






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






4. Rightly stating that no stimulus exists






5. 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






6. 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


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






8. 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.






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






10. 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






11. Takes place when receptors for a particular sense detect a stimulus.






12. Why do cones see better than rods?






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






14. 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.






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






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






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






18. Or overlap of objects shows which objects are closer






19. Defined the Just Noticeable Difference






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






21. Is the tendency to complete incomplete figures






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






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






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






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






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






27. 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






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






29. Saying you detect a stimulus that is not there






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






31. 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.






32. 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






33. Asserts that perception and cognition are largely innate






34. Says that the strength of a stimulus must be significantly increased to produce a slight difference in sensation


35. 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'






36. 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.






37. 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






38. How we organize or experience sensations






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






40. 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.






41. 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.






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






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






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






45. Correctly sensing a stimulus






46. The chemical that aids the receptor cells in transduction






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






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






49. The physical intensity of light






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