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. 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

2. 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.






3. 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.






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






5. 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.






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






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






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






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. Defined the Just Noticeable Difference






11. Along the visual pathway is the...






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






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






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






15. Why do cones see better than rods?






16. 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






17. The physical intensity of light






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






19. 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






20. How movement is perceived though the displacement of objects over time - and how this motion takes place at seemingly different paces for nearby or faraway objects. Ships far away seem to move more slowly than ships moving at the same speed.






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






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






23. Rightly stating that no stimulus exists






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






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






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






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






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

29. Best at seeing fine details






30. 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






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

32. Is the tendency to complete incomplete figures






33. The feeling that results from physical stimulation






34. Correctly sensing a stimulus






35. humans best hear at






36. Located in the back of the eye - receives light images from the lens. It is composed of about 30 million photoreceptor cells and of other cell layers that process information






37. The chemical that aids the receptor cells in transduction






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






39. 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'






40. Or overlap of objects shows which objects are closer






41. We see objects because of the light they reflect






42. Found that infants prefer relatively complex and sensational displays






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






44. 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






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






46. 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.






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






48. 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.






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






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