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






2. We see objects because of the light they reflect






3. Famous for the theory of color blindness






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






5. 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.






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






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






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






9. Consists of the bony labyrinth - a hollow cavity in the temporal bone of the skull with a system of passages comprising two main functional parts: The cochlea - dedicated to hearing; converting sound pressure patterns from the outer ear into electroc






10. Has monocular and binocular cues






11. 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'






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






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






14. 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






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






16. 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.






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






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






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






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






21. 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.






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






23. Proposed the tri-color theory - research shows that the opponent-process theory seems to be at work in the Lateral geniculate body - research shows that the tri-color theory seems to be at work in the Retina






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






25. humans best hear at






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






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






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






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






30. Saying you detect a stimulus that is not there






31. Is the tendency to complete incomplete figures






32. 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

33. 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.






34. Asserts that perception and cognition are largely innate






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






36. Is the inability to recognize faces






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






38. 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.






39. Comes from the complexity of the sound wave






40. Or overlap of objects shows which objects are closer






41. Why do cones see better than rods?






42. Defined the Just Noticeable Difference






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






44. 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.






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






46. Found that infants prefer relatively complex and sensational displays






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






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






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






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