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. Best at seeing fine details






2. 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.






3. We see objects because of the light they reflect






4. humans best hear at






5. 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.






6. Is the inability to recognize faces






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






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






9. 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






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






11. Rightly stating that no stimulus exists






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






13. 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






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






15. 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






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






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






18. Is the tendency to complete incomplete figures






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






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


21. Saying you detect a stimulus that is not there






22. Comes from the complexity of the sound wave






23. Defined the Just Noticeable Difference






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






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






26. 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.






27. Famous for the theory of color blindness






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






29. Also known as just noticeable difference. The minimum difference that must occur between two stimuli - in order for them to be perceived as having different intensities.






30. 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.






31. The physical intensity of light






32. Asserts that perception and cognition are largely innate






33. 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'






34. Proposed the perceptual development and optic array






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






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






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






38. Or overlap of objects shows which objects are closer






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






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






41. Why do cones see better than rods?






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






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






44. 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






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






46. 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






47. Along the visual pathway is the...






48. The overarching Gestalt idea that experience will be organized as meaningful - symmetrical - and simple whenever possible.






49. Found that infants prefer relatively complex and sensational displays






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