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. The part of the world that triggers a particular neuron






2. 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.






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






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






5. The feeling that results from physical stimulation






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






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






8. 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'






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






10. Asserts that perception and cognition are largely innate






11. 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






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






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






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






15. Consists of one optic nerve connection each eye to the brain.






16. Famous for the theory of color blindness






17. Located by the cornea






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






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






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






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






22. Proposed the opponent color/process theory






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






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






25. 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.






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






27. Rightly stating that no stimulus exists






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






29. Is the tendency to complete incomplete figures






30. 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.






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






32. 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.






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






34. Proposed the perceptual development and optic array






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






36. 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






37. Or overlap of objects shows which objects are closer






38. Failing to detect a present stimulus






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






40. Found that infants prefer relatively complex and sensational displays






41. 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






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






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






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






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






46. humans best hear at






47. 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






48. 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






49. We see objects because of the light they reflect






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