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. The optic nerve is made up of...






2. Is the result of regeneration of retinal pigment






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






4. The physical intensity of light






5. Famous for the theory of color blindness






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






7. 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






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






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






10. How we organize or experience sensations






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






12. Asserts that perception and cognition are largely innate






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






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






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






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






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






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






19. We see objects because of the light they reflect






20. 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






21. 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






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






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






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






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






26. 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






27. Rightly stating that no stimulus exists






28. 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






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






30. 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.






31. Allow the cornea to bend (accommodate) in order to focus an image of the outside world onto the retina






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






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






34. 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.






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






36. 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.






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






38. Has monocular and binocular cues






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






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






41. 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

42. Located by the cornea






43. 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






44. Saying you detect a stimulus that is not there






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






46. Correctly sensing a stimulus






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






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

49. After images are perceived because of fatigued receptors. Because our eyes have a partially oppositional system for seeing colors - such as red-green or black-white - once on side is overstimulated and fatigued - it can no longer respond and is overs






50. Is the inability to recognize faces
