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






2. Correctly sensing a stimulus






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






5. 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






6. How we organize or experience sensations






7. Or overlap of objects shows which objects are closer






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






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


10. 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






11. We see objects because of the light they reflect






12. Comes from the complexity of the sound wave






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






14. Failing to detect a present stimulus






15. 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.






16. 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.






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






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


19. 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.






20. Begins with the tympanic membrane (eardrum) which is stretch across the auditory canal. Behind this membrane are the Ossicles (3 small bones) - the last of which is the stapes. Sound vibrations bump against the tympanic membrane - causing the ossicl






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






22. The physical intensity of light






23. 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.






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






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






26. Found that infants prefer relatively complex and sensational displays






27. 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






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






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






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






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






32. Why do cones see better than rods?






33. Is the tendency to complete incomplete figures






34. Saying you detect a stimulus that is not there






35. 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.






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






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






38. Proposed the perceptual development and optic array






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






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






41. Rightly stating that no stimulus exists






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






43. Proposed the opponent color/process theory






44. 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.






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. Is the inability to recognize faces






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






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






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






50. Is the result of regeneration of retinal pigment
