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. 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.






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






3. Asserts that perception and cognition are largely innate






4. 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'






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






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






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






8. 1. closure 2. Proximity 3. Continuation or good continuation 4. Symmetry 5. Constancy 6. Minimum principle






9. Along the visual pathway is the...






10. 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.






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






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






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






14. humans best hear at






15. Correctly sensing a stimulus






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






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






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






19. Located by the cornea






20. Or overlap of objects shows which objects are closer






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






22. We see objects because of the light they reflect






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






24. 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






25. The feeling that results from physical stimulation






26. Why do cones see better than rods?






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






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






29. Rightly stating that no stimulus exists






30. Defined the Just Noticeable Difference






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






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






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






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






35. 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.






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






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






38. Is the tendency to complete incomplete figures






39. 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






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






41. 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.






42. 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






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






44. Proposed the perceptual development and optic array






45. Comes from the complexity of the sound wave






46. 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






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






48. The chemical that aids the receptor cells in transduction






49. 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.






50. 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
