1. The clear protective coating on the outside of the eye






2. 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






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






4. Along the visual pathway is the...






5. Rightly stating that no stimulus exists






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






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






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






10. 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






11. Comes from the complexity of the sound wave






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






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 the tendency to complete incomplete figures






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. The part of the world that triggers a particular neuron






17. Why do cones see better than rods?






18. 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






19. Has monocular and binocular cues






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






21. Is the way that perceived color brightness changes with the level of illumination in the room. With lower levels of illumination - the extremes of the color spectrum (especially red) are seen as less bright






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






23. 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.






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






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






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






27. How we organize or experience sensations






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






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

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






31. Best at seeing fine details






32. Asserts that perception and cognition are largely innate






33. 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

34. 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.






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






36. The chemical that aids the receptor cells in transduction






37. 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.






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






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

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






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






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






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






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






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