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


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






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






4. Saying you detect a stimulus that is not there






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






6. Famous for the theory of color blindness






7. The physical intensity of light






8. 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






9. humans best hear at






10. 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.






11. How we organize or experience sensations






12. Has monocular and binocular cues






13. 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.






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






15. 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.






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






17. 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.






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






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






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


21. 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.






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






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






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






25. Best at seeing fine details






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






27. Has been called the most important depth cue. Our eyes view objects from two slightly different angles - which allows us to create a 3-dimensional figure






28. The chemical that aids the receptor cells in transduction






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






30. We see objects because of the light they reflect






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






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






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






34. Is the result of regeneration of retinal pigment






35. 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'






36. 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.






37. 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






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






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






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






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






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






43. Is the inability to recognize faces






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






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






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






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






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






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






50. Along the visual pathway is the...
