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. How people perceive objects in the way that they are familiar with them - regardless of changes in the actual retinal image. A book - for example - is perceived as rectangular in shape no matter what angle it is seen from.






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






3. Is the result of regeneration of retinal pigment






4. 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.






5. The chemical that aids the receptor cells in transduction






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






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






8. Proposed the perceptual development and optic array






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






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






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






12. 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.






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






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






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






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






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






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

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






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






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






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






23. Correctly sensing a stimulus






24. 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






25. 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.






26. Or overlap of objects shows which objects are closer






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






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






29. 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.






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






31. Has monocular and binocular cues






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






33. 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






34. Famous for the theory of color blindness






35. Along the visual pathway is the...






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






37. humans best hear at






38. Located by the cornea






39. Comes from the complexity of the sound wave






40. 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






41. 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






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






43. Best at seeing fine details






44. 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.






45. 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.






46. Proposed the opponent color/process theory






47. 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.






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. Rightly stating that no stimulus exists






50. How we organize or experience sensations
