Subjects : gre, psychology
Instructions:
  • Answer 50 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

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. Begins with the tympanic membrane (eardrum) which is stretch across the auditory canal. Behind this membrane are the Ossicles (3 small bones) - the last of which is the stapes. Sound vibrations bump against the tympanic membrane - causing the ossicl






2. How we organize or experience sensations






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






4. 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.






5. How movement is perceived though the displacement of objects over time - and how this motion takes place at seemingly different paces for nearby or faraway objects. Ships far away seem to move more slowly than ships moving at the same speed.






6. 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






7. 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.






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






9. Failing to detect a present stimulus






10. The feeling that results from physical stimulation






11. Comes from the complexity of the sound wave






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






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






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






15. Asserts that perception and cognition are largely innate






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






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






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






19. 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






20. Is the inability to recognize faces






21. Along the visual pathway is the...






22. 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'






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






24. 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






25. 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.






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






27. 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






28. Rightly stating that no stimulus exists






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






30. 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.






31. The physical intensity of light






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






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






34. We see objects because of the light they reflect






35. Famous for the theory of color blindness






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






37. 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.






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






39. 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.






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






41. 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






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






43. Found that infants prefer relatively complex and sensational displays






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






45. Located by the cornea






46. Proposed the opponent color/process theory






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






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






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






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