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






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






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






4. Asserts that perception and cognition are largely innate






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






6. 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'






7. 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






8. Is knowing the color of an object even with tinted glasses on






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






10. Found that infants prefer relatively complex and sensational displays






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






12. Has monocular and binocular cues






13. Is the result of regeneration of retinal pigment






14. Comes from the complexity of the sound wave






15. 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.






16. 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.






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






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






19. Best at seeing fine details






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






21. Saying you detect a stimulus that is not there






22. 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.






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






24. Why do cones see better than rods?






25. 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.






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






27. 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.






28. We see objects because of the light they reflect






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






30. Asserts that perception is the sum total of sensory input. The world is understood through bottom-up processing






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






32. The feeling that results from physical stimulation






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

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






35. Or overlap of objects shows which objects are closer






36. 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






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






38. Is the tendency to complete incomplete figures






39. 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.






40. 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.






41. 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.






42. Is the inability to recognize faces






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






44. Along the visual pathway is the...






45. Proposed the perceptual development and optic array






46. Failing to detect a present stimulus






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






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






49. Proposed the opponent color/process theory






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