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






2. Has monocular and binocular cues






3. Best at seeing fine details






4. The feeling that results from physical stimulation






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






6. 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.






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






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






9. 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






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






11. 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.






12. Along the visual pathway is the...






13. Is the tendency to complete incomplete figures






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






15. Located by the cornea






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






17. 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






18. Proposed the perceptual development and optic array






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






20. 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

21. Proposed the opponent color/process theory






22. 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






23. 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






24. 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






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






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






27. 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






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






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






30. Is the inability to recognize faces






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






32. How we organize or experience sensations






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






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

36. Rightly stating that no stimulus exists






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






38. humans best hear at






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






40. The pace of vibrations or sound waves per second for a particular sound - determines pitch. Frequencies are measured in Hertz






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






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






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






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






45. The center of the retina; has the greatest visual acuity






46. Failing to detect a present stimulus






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

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. 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.






50. 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
