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






2. 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






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






4. 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.






5. 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






6. 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.






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






8. How we organize or experience sensations






9. 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.






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






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






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






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






14. 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






15. 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.






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






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






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






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


20. humans best hear at






21. Best at seeing fine details






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






23. Correctly sensing a stimulus






24. 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






25. Defined the Just Noticeable Difference






26. Has monocular and binocular cues






27. 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






28. 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.






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






30. 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.






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






32. Why do cones see better than rods?






33. 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






34. We see objects because of the light they reflect






35. The chemical that aids the receptor cells in transduction






36. Found that infants prefer relatively complex and sensational displays






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


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






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






40. Proposed the perceptual development and optic array






41. Or overlap of objects shows which objects are closer






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






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






44. Comes from the complexity of the sound wave






45. 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






46. 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.






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






48. 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.






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






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