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






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






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






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






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






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






7. Correctly sensing a stimulus






8. The physical intensity of light






9. 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






10. 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.






11. 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


12. 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






13. 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.






14. 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






15. Rightly stating that no stimulus exists






16. Proposed the perceptual development and optic array






17. Is the inability to recognize faces






18. Best at seeing fine details






19. Has monocular and binocular cues






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






21. Why do cones see better than rods?






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






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






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






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






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






27. 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






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






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






30. The optic nerve is made up of...






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






32. The feeling that results from physical stimulation






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






34. Located by the cornea






35. Failing to detect a present stimulus






36. Or overlap of objects shows which objects are closer






37. 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






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






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






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






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






42. 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






43. We see objects because of the light they reflect






44. 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.






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






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






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






48. 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






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






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