This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. After the optic chasm - information travels to the...






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






3. Found that infants prefer relatively complex and sensational displays






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






5. 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.






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


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






8. Defined the Just Noticeable Difference






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






10. Correctly sensing a stimulus






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






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






13. Asserts that perception and cognition are largely innate






14. 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






15. 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






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






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






18. Has monocular and binocular cues






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






20. Best at seeing fine details






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






22. Saying you detect a stimulus that is not there






23. Why do cones see better than rods?






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






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






26. The feeling that results from physical stimulation






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






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


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






30. 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.






31. 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'






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






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






34. 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






35. Famous for the theory of color blindness






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






37. 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






38. Proposed the opponent color/process theory






39. Comes from the complexity of the sound wave






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






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






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






43. 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






44. 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.






45. 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.






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






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






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






49. 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






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