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






3. Correctly sensing a stimulus






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






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






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






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






8. Is the inability to recognize faces






9. 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.






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






11. Proposed the opponent color/process theory






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






13. 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






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






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






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






17. Located by the cornea






18. Why do cones see better than rods?






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






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






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






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






23. Along the visual pathway is the...






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






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






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






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


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






29. 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.






30. The chemical that aids the receptor cells in transduction






31. Also known as color - is the dominant wavelength of light






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






33. Is the tendency to complete incomplete figures






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






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






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






37. Failing to detect a present stimulus






38. 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.






39. 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






40. Or overlap of objects shows which objects are closer






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






42. 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'






43. Refers to the relationship between the meaningful part of a picture and the background






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






45. Has monocular and binocular cues






46. Defined the Just Noticeable Difference






47. 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.






48. 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.






49. 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






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