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. 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






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






3. Developed the visual cliff to study whether depth perception was 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. 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






6. Located by the cornea






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






8. Correctly sensing a stimulus






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






10. Is the inability to recognize faces






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






12. Proposed the perceptual development and optic array






13. Famous for the theory of color blindness






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






15. Has monocular and binocular cues






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






17. Is the tendency to complete incomplete figures






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






19. Is the result of regeneration of retinal pigment






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






21. 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

22. Found that infants prefer relatively complex and sensational displays






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






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






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






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






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






28. 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






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






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






31. Comes from the complexity of the sound wave






32. Or overlap of objects shows which objects are closer






33. 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.






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






35. Best at seeing fine details






36. 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.






37. 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






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






39. 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






40. 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






41. 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






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

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






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






45. The feeling that results from physical stimulation






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






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






48. 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.






49. 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.






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