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. Found that infants prefer relatively complex and sensational displays






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






3. Why do cones see better than rods?






4. The feeling that results from physical stimulation






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






6. 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.






7. 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.






8. 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.






9. Is the tendency to complete incomplete figures






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






11. 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.






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






13. 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






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






15. Failing to detect a present stimulus






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

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






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






20. We see objects because of the light they reflect






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

22. Located by the cornea






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






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






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






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






27. How we organize or experience sensations






28. 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






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






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






31. Electrical impulses travel down these to the brain - where the information is understood






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






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






35. Can be perceived as two different things depending on how you look at them






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






37. Along the visual pathway is the...






38. Proposed the perceptual development and optic array






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






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






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






42. Has monocular and binocular cues






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






44. Saying you detect a stimulus that is not there






45. Or overlap of objects shows which objects are closer






46. The chemical that aids the receptor cells in transduction






47. Rightly stating that no stimulus exists






48. Is the result of regeneration of retinal pigment






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






50. 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
