1. 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






2. Discovered that cells in the visual cortex were so complex and specialized that they respond to certain types of stimuli. For example - some cells only respond to vertical lines - whereas some respond to only right angles.






3. Comes from the complexity of the sound wave






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






5. Located by the cornea






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

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






8. 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.






9. Failing to detect a present stimulus






10. 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






11. 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.






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






13. Correctly sensing a stimulus






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






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






16. Has monocular and binocular cues






17. How we organize or experience sensations






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






19. Saying you detect a stimulus that is not there






20. Proposed the perceptual development and optic array






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






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






23. 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.






24. Rightly stating that no stimulus exists






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






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






27. 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.






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






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






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






31. 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






32. Is the result of regeneration of retinal pigment






33. 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






34. 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






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






36. Famous for the theory of color blindness






37. Found that infants prefer relatively complex and sensational displays






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






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

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






41. The physical intensity of light






42. 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






43. 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.






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






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






46. 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.






47. 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.






48. Why do cones see better than rods?






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






50. Or overlap of objects shows which objects are closer
