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






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






6. 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






7. 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

8. 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






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






10. Correctly sensing a stimulus






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






12. 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






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






14. 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.






15. 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






16. Proposed the perceptual development and optic array






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






18. 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






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






20. How people perceive objects in the way that they are familiar with them - regardless of changes in the actual retinal image. A book - for example - is perceived as rectangular in shape no matter what angle it is seen from.






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






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






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






24. 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.






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






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






27. Can be perceived as two different things depending on how you look at them






28. Are particularly sensitive to dim light and are used for night vision. They are also concentrated along the sides of the retina - making them extremely important for peripheral vision






29. 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






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






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






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






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






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






35. 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'






36. The feeling that results from physical stimulation






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






38. Proposed the opponent color/process theory






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






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






41. Has monocular and binocular cues






42. Allow the cornea to bend (accommodate) in order to focus an image of the outside world onto the retina






43. 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.






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






45. Is the inability to recognize faces






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






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






48. Why do cones see better than rods?






49. 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






50. Saying you detect a stimulus that is not there
