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






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






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






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






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






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






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

8. 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.






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






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






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






12. Failing to detect a present stimulus






13. Is the tendency to complete incomplete figures






14. 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






15. Saying you detect a stimulus that is not there






16. Is the result of regeneration of retinal pigment






17. 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.






18. Proposed the opponent color/process theory






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






20. 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.






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






22. Located by the cornea






23. humans best hear at






24. How we organize or experience sensations






25. 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'






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






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






28. 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






29. 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

30. Best at seeing fine details






31. How movement is perceived though the displacement of objects over time - and how this motion takes place at seemingly different paces for nearby or faraway objects. Ships far away seem to move more slowly than ships moving at the same speed.






32. 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






33. 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






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






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






36. 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.






37. Asserts that perception and cognition are largely innate






38. Why do cones see better than rods?






39. 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.






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






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






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






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






44. Is the inability to recognize faces






45. Has monocular and binocular cues






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






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






48. Has been called the most important depth cue. Our eyes view objects from two slightly different angles - which allows us to create a 3-dimensional figure






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






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