1. 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.






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






3. 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






4. 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






5. Is the tendency to complete incomplete figures






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






7. 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.






8. Is the inability to recognize faces






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






10. 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






11. 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






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






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






14. Best at seeing fine details






15. 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






16. Why do cones see better than rods?






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






18. How we organize or experience sensations






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






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






21. We see objects because of the light they reflect






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






23. Correctly sensing a stimulus






24. Along the visual pathway is the...






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

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






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






28. 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

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






30. Saying you detect a stimulus that is not there






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






32. The physical intensity of light






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






34. The chemical that aids the receptor cells in transduction






35. Defined the Just Noticeable Difference






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






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






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






39. Rightly stating that no stimulus exists






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






41. Failing to detect a present stimulus






42. 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.






43. Famous for the theory of color blindness






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






45. 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.






46. Found that infants prefer relatively complex and sensational displays






47. Proposed the opponent color/process theory






48. The feeling that results from physical stimulation






49. Is the tendency to create a whole or detailed figure based on our expectations rather than what is seen






50. 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'
