1. Is the tendency to complete incomplete figures






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






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






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






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






6. 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.






7. 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






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






9. The physical intensity of a sound wave largely determines loudness






10. Factors into why we see what we expect to see






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






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






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






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






15. He tendency to group together items that are near each other






16. Is the inability to recognize faces






17. Saying you detect a stimulus that is not there






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






19. Is when two horizontal lines of equal length appear unequal because of two vertical lines that slant inward






20. 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






21. 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.






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

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






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






27. Comes from the complexity of the sound wave






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






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






30. 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






31. 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.






32. 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'






33. 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






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






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






36. Failing to detect a present stimulus






37. How we organize or experience sensations






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






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

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






41. 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.






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






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