3. humans best hear at






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






5. 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.






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






7. The physical intensity of light






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






9. 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.






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






11. 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






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


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






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






15. 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






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






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






18. 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

24. Asserts that perception and cognition are largely innate






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






26. 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

35. 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.






36. 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.






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






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

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






44. 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

46. Along the visual pathway is the...






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






48. 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.






49. 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
