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. Defined the Just Noticeable Difference






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






3. The feeling that results from physical stimulation






4. Failing to detect a present stimulus






5. Is the inability to recognize faces






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






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






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






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






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






11. Asserts that perception and cognition are largely innate






12. 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






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






14. The chemical that aids the receptor cells in transduction






15. 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.






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






17. 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






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

19. Proposed the tri-color theory - research shows that the opponent-process theory seems to be at work in the Lateral geniculate body - research shows that the tri-color theory seems to be at work in the Retina






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






21. 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.






22. Is the tendency to complete incomplete figures






23. After images are perceived because of fatigued receptors. Because our eyes have a partially oppositional system for seeing colors - such as red-green or black-white - once on side is overstimulated and fatigued - it can no longer respond and is overs






24. The physical intensity of light






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






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






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






28. The tendency to perceive a smooth motion. This explains why motion is perceived when there is none - often by the use of flashing lights or rapidly shown still-fram pictures - such as in the perception of cartoons. This is apparent motion






29. Proposed the perceptual development and optic array






30. 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.






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






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






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






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






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






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






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






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






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






40. After the optic chasm - information travels to the...






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






42. Rightly stating that no stimulus exists






43. Best at seeing fine details






44. Has monocular and binocular cues






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






46. Famous for the theory of color blindness






47. Found that infants prefer relatively complex and sensational displays






48. Discovered that cells in the visual cortex were so complex and specialized that they respond to certain types of stimuli. For example - some cells only respond to vertical lines - whereas some respond to only right angles.






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






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