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. Factors into why we see what we expect to see






3. Famous for the theory of color blindness






4. Failing to detect a present stimulus






5. Is the result of regeneration of retinal pigment






6. 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.






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






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






9. 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






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






11. 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'






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


13. Comes from the complexity of the sound wave






14. Is the tendency to complete incomplete figures






15. The chemical that aids the receptor cells in transduction






16. Has monocular and binocular cues






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






18. 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.






19. The feeling that results from physical stimulation






20. 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.






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






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






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






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






25. Defined the Just Noticeable Difference






26. How we organize or experience sensations






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






28. Or overlap of objects shows which objects are closer






29. 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






30. 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.






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






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






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






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






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






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






37. Is gained by features we are familiar with - such as two seemingly parallel lines that converge with distance






38. 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.






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






40. 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






41. We see objects because of the light they reflect






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






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






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






45. 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






46. Rightly stating that no stimulus exists






47. 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.






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






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






50. 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
