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. 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






2. Proposed the opponent color/process theory






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






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






5. Why do cones see better than rods?






6. 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.






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






8. humans best hear at






9. 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






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






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






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






13. 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.






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






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






16. Found that infants prefer relatively complex and sensational displays






17. We see objects because of the light they reflect






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






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






20. Asserts that perception and cognition are largely innate






21. Correctly sensing a stimulus






22. Rightly stating that no stimulus exists






23. The chemical that aids the receptor cells in transduction






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






25. 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






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






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






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






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






30. 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






31. 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.






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






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






34. 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.






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






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






37. Defined the Just Noticeable Difference






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






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






40. The feeling that results from physical stimulation






41. How we organize or experience sensations






42. Saying you detect a stimulus that is not there






43. The physical intensity of light






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






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






46. 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






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






48. Involves both innate/sensory and is partially learned/conceptual






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






50. Proposed the perceptual development and optic array
