1. Along the visual pathway is the...






2. Defined the Just Noticeable Difference






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






4. 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






5. Saying you detect a stimulus that is not there






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






7. 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.






8. Proposed the opponent color/process theory






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






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






11. 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






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






13. The physical intensity of light






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






15. We see objects because of the light they reflect






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






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






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






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






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






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






22. Is the inability to recognize faces






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






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






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






26. 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






27. 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






28. 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.






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






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






31. Or overlap of objects shows which objects are closer






32. Correctly sensing a stimulus






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






34. Famous for the theory of color blindness






35. Failing to detect a present stimulus






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






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






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






39. 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






40. Found that infants prefer relatively complex and sensational displays






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






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

43. 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'






44. Proposed the tri-color theory - research shows that the opponent-process theory seems to be at work in the Lateral geniculate body - research shows that the tri-color theory seems to be at work in the Retina






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






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






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






48. Is the tendency to complete incomplete figures






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