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






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






3. 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






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






5. The feeling that results from physical stimulation






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






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






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






9. 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.






10. 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






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






12. Why do cones see better than rods?






13. 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


14. 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.






15. 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.






16. 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'






17. Asserts that perception and cognition are largely innate






18. 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






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






20. Proposed the perceptual development and optic array






21. Famous for the theory of color blindness






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






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






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






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






26. 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.






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






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






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






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






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






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






33. Is the tendency to complete incomplete figures






34. humans best hear at






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






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






37. Found that infants prefer relatively complex and sensational displays






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






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






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






41. 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.






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






43. Failing to detect a present stimulus






44. Along the visual pathway is the...






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


46. Rightly stating that no stimulus exists






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






48. Best at seeing fine details






49. Has monocular and binocular cues






50. Comes from the complexity of the sound wave
