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. Found that infants prefer relatively complex and sensational displays






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






3. 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






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






5. Asserts that perception and cognition are largely innate






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






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






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






9. The chemical that aids the receptor cells in transduction






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






11. 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






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






13. Saying you detect a stimulus that is not there






14. 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.






15. Has monocular and binocular cues






16. The physical intensity of light






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






18. 1. closure 2. Proximity 3. Continuation or good continuation 4. Symmetry 5. Constancy 6. Minimum principle






19. 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






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






22. Proposed the opponent color/process theory






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






24. 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.






25. 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






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






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






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






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






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






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






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






33. Famous for the theory of color blindness






34. Along the visual pathway is the...






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






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






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






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






40. Failing to detect a present stimulus






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






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






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






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






45. 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'






46. 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.






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






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






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