1. 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.






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






3. 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.






4. 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






5. Correctly sensing a stimulus






6. 1. Reception 2. Sensory Transduction 3. Neural Pathways






7. 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






8. Also known as just noticeable difference. The minimum difference that must occur between two stimuli - in order for them to be perceived as having different intensities.






9. Famous for the theory of color blindness






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






11. The feeling that results from physical stimulation






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






13. Located by the cornea






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






15. 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.






16. Asserts that perception and cognition are largely innate






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. Defined the Just Noticeable Difference






19. 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






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






21. Also known as color - is the dominant wavelength of light






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






23. The physical intensity of light






24. 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'






25. 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






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






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






28. 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

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






30. 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






31. Or overlap of objects shows which objects are closer






32. We see objects because of the light they reflect






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






34. humans best hear at






35. Along the visual pathway is the...






36. Asserts that perception is the sum total of sensory input. The world is understood through bottom-up processing






37. Has monocular and binocular cues






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






39. Failing to detect a present stimulus






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






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






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






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






44. Is the inability to recognize faces






45. Proposed the perceptual development and optic array






46. 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






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






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