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. Or overlap of objects shows which objects are closer






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






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






4. The clear protective coating on the outside of the eye






5. 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






6. 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.






7. Rightly stating that no stimulus exists






8. Proposed the perceptual development and optic array






9. 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






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






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






12. 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.






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. Is the result of regeneration of retinal pigment






15. 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.






16. Best at seeing fine details






17. The physical intensity of light






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






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






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






21. Is the inability to recognize faces






22. 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.






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






24. 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






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






26. 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

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






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






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






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






31. Defined the Just Noticeable Difference






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






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. Is the minimum amount of stimuli that can be detected 50% of the time






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






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






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






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






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






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






41. Along the visual pathway is the...






42. Is the tendency to complete incomplete figures






43. Saying you detect a stimulus that is not there






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






45. 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.






46. We see objects because of the light they reflect






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






48. 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






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






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