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 overarching Gestalt idea that experience will be organized as meaningful - symmetrical - and simple whenever possible.






2. Located by the cornea






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






4. Correctly sensing a stimulus






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






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






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






8. Proposed the opponent color/process theory






9. Is the result of regeneration of retinal pigment






10. 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.






11. The feeling that results from physical stimulation






12. Along the visual pathway is the...






13. Failing to detect a present stimulus






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






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






16. How we organize or experience sensations






17. Proposed the perceptual development and optic array






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






19. 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






20. 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






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






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






23. humans best hear at






24. We see objects because of the light they reflect






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






26. Asserts that perception and cognition are largely innate






27. The part of the world that triggers a particular neuron






28. 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.






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






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






31. 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






32. 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.






33. Why do cones see better than rods?






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






35. 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






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






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






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






39. Rightly stating that no stimulus exists






40. Or overlap of objects shows which objects are closer






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






42. Famous for the theory of color blindness






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


44. 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'






45. Saying you detect a stimulus that is not there






46. 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


47. 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






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






49. 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.






50. 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.
