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. Why do cones see better than rods?






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






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


5. Asserts that perception and cognition are largely innate






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






7. 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






8. A theory for color vision. It suggests that two types of color sensitive cells exist: Cones that respond to blue-yellow colors and cones that respond to red-green. When one color of the cone is stimulated - the other is inhibited.






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






10. 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


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






12. 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.






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






14. The physical intensity of light






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






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






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






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






19. 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'






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






21. Is the tendency to complete incomplete figures






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






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






24. Or overlap of objects shows which objects are closer






25. 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






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






27. 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.






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






29. Famous for the theory of color blindness






30. Proposed the opponent color/process theory






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






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






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






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






35. Comes from the complexity of the sound wave






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






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






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






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






40. 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






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






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






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






44. We see objects because of the light they reflect






45. Failing to detect a present stimulus






46. 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






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






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






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






50. Is the inability to recognize faces
