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. Or overlap of objects shows which objects are closer






2. Failing to detect a present stimulus






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






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






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






6. 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






7. 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.






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






9. We see objects because of the light they reflect






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






11. Asserts that perception and cognition are largely innate






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






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






14. Best at seeing fine details






15. Famous for the theory of color blindness






16. Discovered that cells in the visual cortex were so complex and specialized that they respond to certain types of stimuli. For example - some cells only respond to vertical lines - whereas some respond to only right angles.






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






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






19. 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.






20. Correctly sensing a stimulus






21. Defined the Just Noticeable Difference






22. 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






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






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






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






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






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






28. Is the result of regeneration of retinal pigment






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






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






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






32. Has monocular and binocular cues






33. 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






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






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






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






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






38. Gives us clues about how far away an object is if we know about how big the object should be






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






40. 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






41. 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






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






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






44. How we organize or experience sensations






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






46. Along the visual pathway is the...






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






48. Comes from the complexity of the sound wave






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






50. Individuals are partly motivated by rewards and costs in detection. The interplay between response bias and stimulus intensity determines responses
