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 feeling that results from physical stimulation






2. 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.






3. Is the result of regeneration of retinal pigment






4. 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.






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






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






7. 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.






8. Has monocular and binocular cues






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






10. humans best hear at






11. Located by the cornea






12. 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






13. We see objects because of the light they reflect






14. 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.






15. Defined the Just Noticeable Difference






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






17. The physical intensity of light






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






19. 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






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






22. 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

23. Is the tendency to complete incomplete figures






24. Saying you detect a stimulus that is not there






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






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






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






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






29. 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.






30. Asserts that perception and cognition are largely innate






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






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






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. The physical intensity of a sound wave largely determines loudness






35. Or overlap of objects shows which objects are closer






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






37. Along the visual pathway is the...






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






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






40. 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.






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






42. Best at seeing fine details






43. 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






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






45. 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.






46. Proposed the perceptual development and optic array






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






48. Found that infants prefer relatively complex and sensational displays






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






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