1. Proposed the opponent color/process theory






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






3. 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






4. Best at seeing fine details






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






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






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






9. 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.






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






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






12. 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.






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






14. 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






15. Why do cones see better than rods?






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






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






20. How we organize or experience sensations






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






22. Located by the cornea






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






24. Saying you detect a stimulus that is not there






25. Is the inability to recognize faces






26. Found that infants prefer relatively complex and sensational displays






27. 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.






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






29. 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






30. Has monocular and binocular cues






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






32. 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.






33. Famous for the theory of color blindness






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






35. The chemical that aids the receptor cells in transduction






36. 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






37. Failing to detect a present stimulus






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






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






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






41. Is the tendency to complete incomplete figures






42. Suggests that subjects detect stimuli not only because they can but also because they want to. TSD factors motivation into the picture.

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






44. Asserts that perception and cognition are largely innate






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






46. 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






47. The feeling that results from physical stimulation






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






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






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