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






4. Has monocular and binocular cues






5. 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






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






7. The feeling that results from physical stimulation






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






9. The physical intensity of light






10. Comes from the complexity of the sound wave






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






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






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






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






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






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






17. Correctly sensing a stimulus






18. The chemical that aids the receptor cells in transduction






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






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






21. How we organize or experience sensations






22. 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






23. 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.






24. Rightly stating that no stimulus exists






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

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






28. 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.






29. Or overlap of objects shows which objects are closer






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






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. 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






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






34. 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






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






36. Allows the eyes to see contrast and prevents repetitive information from being sent to the brain. Once the receptor cell is stimulated - the others nearby are inhibited.






37. Saying you detect a stimulus that is not there






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

39. 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.






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






41. Is the tendency to complete incomplete figures






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






43. 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






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






45. 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'
