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






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






3. 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






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. 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.






6. Along the visual pathway is the...






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. 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






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






10. Correctly sensing a stimulus






11. 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.






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






13. Failing to detect a present stimulus






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






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






16. 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.






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






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






19. Asserts that perception and cognition are largely innate






20. 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






21. 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.






22. Proposed the opponent color/process theory






23. Is the inability to recognize faces






24. humans best hear at






25. The feeling that results from physical stimulation






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






27. Has monocular and binocular cues






28. 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






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






30. 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'






31. Defined the Just Noticeable Difference






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






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






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






35. Rightly stating that no stimulus exists






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






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






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






39. Is the result of regeneration of retinal pigment






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






41. Why do cones see better than rods?






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






43. 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






44. Saying you detect a stimulus that is not there






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

46. 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






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






48. 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.






49. Is the tendency to complete incomplete figures






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