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






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






3. Rightly stating that no stimulus exists






4. 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






5. Along the visual pathway is the...






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






7. We see objects because of the light they reflect






8. 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.






9. 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






10. Comes from the complexity of the sound wave






11. 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






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






13. Asserts that perception and cognition are largely innate






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






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






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






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






18. Located in the back of the eye - receives light images from the lens. It is composed of about 30 million photoreceptor cells and of other cell layers that process information






19. Defined the Just Noticeable Difference






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






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






22. 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'






23. Famous for the theory of color blindness






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






25. 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.






26. 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.






27. 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.






28. 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






29. The physical intensity of light






30. Is the tendency to complete incomplete figures






31. Saying you detect a stimulus that is not there






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






33. Proposed the perceptual development and optic array






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






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






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






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






38. 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






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






40. 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.






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






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






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






44. Is the inability to recognize faces






45. humans best hear at






46. Found that infants prefer relatively complex and sensational displays






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






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






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






50. Proposed the opponent color/process theory
