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. humans best hear at






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






3. Proposed the perceptual development and optic array






4. 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






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






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






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






8. 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






9. 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


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






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






12. Asserts that perception and cognition are largely innate






13. Is the inability to recognize faces






14. 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






15. Says that the strength of a stimulus must be significantly increased to produce a slight difference in sensation


16. 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.






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






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






19. 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.






20. Has monocular and binocular cues






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






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






23. Is the tendency to complete incomplete figures






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






25. Correctly sensing a stimulus






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






27. Comes from the complexity of the sound wave






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






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






30. 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'






31. Along the visual pathway is the...






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






33. We see objects because of the light they reflect






34. Failing to detect a present stimulus






35. Best at seeing fine details






36. 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.






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






38. 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.






39. 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






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






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






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






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






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






45. The physical intensity of light






46. The chemical that aids the receptor cells in transduction






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






48. Famous for the theory of color blindness






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






50. Suggests that subjects detect stimuli not only because they can but also because they want to. TSD factors motivation into the picture.
