1. Famous for the theory of color blindness






2. 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






3. Proposed the perceptual development and optic array






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






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






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






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






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






9. Failing to detect a present stimulus






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






11. 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






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






13. 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






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






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






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






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






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






19. Has monocular and binocular cues






20. 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.






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






22. 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.






23. Is the tendency to complete incomplete figures






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






25. Is the result of regeneration of retinal pigment






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






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






29. 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






30. Ambiguous figures - such as the Rubin vase. They can be perceived as two different things depending on which part you see as the figure and which part you see as the background.






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






32. The feeling that results from physical stimulation






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






34. How we organize or experience sensations






35. Along the visual pathway is the...






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






37. Rightly stating that no stimulus exists






38. humans best hear at






39. Comes from the complexity of the sound wave






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






41. Saying you detect a stimulus that is not there






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






43. Located by the cornea






44. Or overlap of objects shows which objects are closer






45. 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.






46. Correctly sensing a stimulus






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






48. Is the inability to recognize faces






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






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