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






2. 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






3. 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






4. 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.






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






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






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






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






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






10. Best at seeing fine details






11. Famous for the theory of color blindness






12. 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






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






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






15. 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.






16. 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.






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

21. 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






22. Also known as just noticeable difference. The minimum difference that must occur between two stimuli - in order for them to be perceived as having different intensities.






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






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

25. 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






26. Individuals are partly motivated by rewards and costs in detection. The interplay between response bias and stimulus intensity determines responses






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






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. humans best hear at






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






31. 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






32. 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.






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

34. 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






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






36. Correctly sensing a stimulus






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






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






39. How we organize or experience sensations






40. Defined the Just Noticeable Difference






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






42. We see objects because of the light they reflect






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






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






45. 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






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






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






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