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






2. How we organize or experience sensations






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






4. After images are perceived because of fatigued receptors. Because our eyes have a partially oppositional system for seeing colors - such as red-green or black-white - once on side is overstimulated and fatigued - it can no longer respond and is overs






5. Saying you detect a stimulus that is not there






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






7. Are concentrated in the center of the retina. They are sensitive to color and daylight vision.






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






9. humans best hear at






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






11. 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






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






13. Comes from the complexity of the sound wave






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






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






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






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






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






19. Proposed the perceptual development and optic array






20. Located by the cornea






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






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






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






24. Or overlap of objects shows which objects are closer






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






26. Is the inability to recognize faces






27. Rightly stating that no stimulus exists






28. 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'






29. Located in the back of the eye - receives light images from the lens. It is composed of about 30 million photoreceptor cells and of other cell layers that process information






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






31. Has monocular and binocular cues






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

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






34. 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.






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

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. We see objects because of the light they reflect






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






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






40. Failing to detect a present stimulus






41. 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






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






43. 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






44. 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.






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. Found that infants prefer relatively complex and sensational displays






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






49. The chemical that aids the receptor cells in transduction






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