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 clear protective coating on the outside of the eye






2. Along the visual pathway is the...






3. The chemical that aids the receptor cells in transduction






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






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






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






7. 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






8. Correctly sensing a stimulus






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






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






11. 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.






12. 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.






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






14. 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






15. The physical intensity of light






16. Ambiguous figures - such as the Rubin vase. They can be perceived as two different things depending on which part you see as the figure and which part you see as the background.






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






18. Proposed the opponent color/process theory






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






20. Asserts that perception and cognition are largely innate






21. 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






22. We see objects because of the light they reflect






23. 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






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






25. Rightly stating that no stimulus exists






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






27. 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






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






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






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






31. Proposed the perceptual development and optic array






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






33. Comes from the complexity of the sound wave






34. Defined the Just Noticeable Difference






35. Is the result of regeneration of retinal pigment






36. Located by the cornea






37. 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.






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






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






40. Is the inability to recognize faces






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. Failing to detect a present stimulus






43. 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.






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






45. Found that infants prefer relatively complex and sensational displays






46. Consists of the bony labyrinth - a hollow cavity in the temporal bone of the skull with a system of passages comprising two main functional parts: The cochlea - dedicated to hearing; converting sound pressure patterns from the outer ear into electroc






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






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






49. Famous for the theory of color blindness






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