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






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






3. Factors into why we see what we expect to see






4. Correctly sensing a stimulus






5. 1. Reception 2. Sensory Transduction 3. Neural Pathways






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






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






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






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






10. Along the visual pathway is the...






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






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






13. Failing to detect a present stimulus






14. Proposed the opponent color/process theory






15. We see objects because of the light they reflect






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






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






18. 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

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






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






21. Located by the cornea






22. 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.






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






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






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






26. How we organize or experience sensations






27. Saying you detect a stimulus that is not there






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






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






30. 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






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






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






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






34. The physical intensity of light






35. Comes from the complexity of the sound wave






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






37. Asserts that perception and cognition are largely innate






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






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






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






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






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






43. 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






44. 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.






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






46. Allow the cornea to bend (accommodate) in order to focus an image of the outside world onto the retina






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






48. 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






49. 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






50. 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.
