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 center of the retina; has the greatest visual acuity






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






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






4. He tendency to group together items that are near each other






5. Applies to all senses but only to a limited range of intensities. The law states that a stimulus needs to be increased by a constant fraction of its original value in order to be noticeably different

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






7. 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






8. 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.






9. Saying you detect a stimulus that is not there






10. 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






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






12. 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.






13. The chemical that aids the receptor cells in transduction






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






15. We see objects because of the light they reflect






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






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






18. Has monocular and binocular cues






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






20. Correctly sensing a stimulus






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






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






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






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






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






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






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

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






29. 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






30. Is the result of regeneration of retinal pigment






31. Is the inability to recognize faces






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






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






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






35. 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.






36. Famous for the theory of color blindness






37. Comes from the complexity of the sound wave






38. The physical intensity of light






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






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






41. 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.






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






43. 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.






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






45. 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.






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

47. The moon looks larger when we see it on the horizon than when we see it in the sky. This is because the horizon contains visual cues that make the moon seem more distant than the overhead sky.






48. Found that infants prefer relatively complex and sensational displays






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






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