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






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






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






4. Is the result of regeneration of retinal pigment






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






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






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






8. Found that infants prefer relatively complex and sensational displays






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






10. Along the visual pathway is the...






11. 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.






12. Is the tendency to complete incomplete figures






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






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






15. 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






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






17. Comes from the complexity of the sound wave






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






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






20. 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.






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






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






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






24. 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






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






26. 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






27. Why do cones see better than rods?






28. 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






29. Proposed the perceptual development and optic array






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






31. 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






32. 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'






33. We see objects because of the light they reflect






34. Is the tendency to see what is easiest or logical to see






35. 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






36. 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.






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. The chemical that aids the receptor cells in transduction






39. Best at seeing fine details






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






41. Is the inability to recognize faces






42. 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.






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






44. Is the upper limit above which the stimuli can no longer be perceived. -The highest pitch sound a human could hear






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






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






47. 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.






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






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






50. humans best hear at
