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. 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.






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






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






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






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






6. Refers to the entire span that can be perceived or detected by the eye at a given moment.






7. Why do cones see better than rods?






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






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






10. 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






11. Rightly stating that no stimulus exists






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






13. 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.






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






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






16. The chemical that aids the receptor cells in transduction






17. Proposed the perceptual development and optic array






18. Correctly sensing a stimulus






19. Has monocular and binocular cues






20. 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

21. Famous for the theory of color blindness






22. 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






23. 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.






24. The feeling that results from physical stimulation






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






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






27. Is the tendency to complete incomplete figures






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






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






30. Saying you detect a stimulus that is not there






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






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






33. 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.






34. Asserts that perception and cognition are largely innate






35. Along the visual pathway is the...






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






37. 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.






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






39. Comes from the complexity of the sound wave






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






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






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






43. Is the inability to recognize faces






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






45. Is the way that perceived color brightness changes with the level of illumination in the room. With lower levels of illumination - the extremes of the color spectrum (especially red) are seen as less bright






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






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






48. Defined the Just Noticeable Difference






49. 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.






50. Has been called the most important depth cue. Our eyes view objects from two slightly different angles - which allows us to create a 3-dimensional figure
