GRE Psychology: Perception Sensation

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 physical intensity of light






2. 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






3. Or overlap of objects shows which objects are closer






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






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. 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.






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






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






9. Best at seeing fine details






10. Failing to detect a present stimulus






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






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






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






14. Famous for the theory of color blindness






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






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






17. Proposed the perceptual development and optic array






18. The chemical that aids the receptor cells in transduction






19. Along the visual pathway is the...






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






21. 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






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






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






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






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






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






27. We see objects because of the light they reflect






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






29. 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






30. Rightly stating that no stimulus exists






31. 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.






32. Why do cones see better than rods?






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






34. 1. Reception 2. Sensory Transduction 3. Neural Pathways






35. Saying you detect a stimulus that is not there






36. Comes from the complexity of the sound wave






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






38. 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






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






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






41. 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






42. Correctly sensing a stimulus






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






44. Proposed the opponent color/process theory






45. 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.






46. Found that infants prefer relatively complex and sensational displays






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






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






49. How we organize or experience sensations






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