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. 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.






2. 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






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






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






5. Or overlap of objects shows which objects are closer






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






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






8. Is the inability to recognize faces






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






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






12. 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






13. Located by the cornea






14. Rightly stating that no stimulus exists






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






16. Proposed the perceptual development and optic array






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






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






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






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






22. Is the result of regeneration of retinal pigment






23. Has monocular and binocular cues






24. 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'






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






26. 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.






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. 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.






29. Asserts that perception and cognition are largely innate






30. Best at seeing fine details






31. humans best hear at






32. 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






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






34. 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.






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






36. Found that infants prefer relatively complex and sensational displays






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






38. The physical intensity of light






39. We see objects because of the light they reflect






40. Saying you detect a stimulus that is not there






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






42. How we organize or experience sensations






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






44. Is when two horizontal lines of equal length appear unequal because of two vertical lines that slant inward






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






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






47. Along the visual pathway is the...






48. 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.






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






50. 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.
