2. How we organize or experience sensations






3. Found that infants prefer relatively complex and sensational displays

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






7. 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.






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






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






10. 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






11. The chemical that aids the receptor cells in transduction






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






13. 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'






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






15. We see objects because of the light they reflect






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






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






18. 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

24. Proposed the opponent color/process theory






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






26. Is the inability to recognize faces






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

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






29. Rightly stating that no stimulus exists






30. Defined the Just Noticeable Difference






31. Or overlap of objects shows which objects are closer






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






33. 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.






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






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






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






38. 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






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






40. 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.






41. 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






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






43. The feeling that results from physical stimulation






44. Why do cones see better than rods?






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

47. Comes from the complexity of the sound wave






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