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. 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






2. The physical intensity of a sound wave largely determines loudness






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






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






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






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






7. Or overlap of objects shows which objects are closer






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






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






10. Asserts that perception and cognition are largely innate






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






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






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






14. 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






15. 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






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






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






18. Found that infants prefer relatively complex and sensational displays






19. Is the inability to recognize faces






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






21. 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.






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






23. 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.






24. 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






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






26. Proposed the perceptual development and optic array






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






28. Located by the cornea






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






30. We see objects because of the light they reflect






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






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






33. 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.






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






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






36. Failing to detect a present stimulus






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






38. Ambiguous figures - such as the Rubin vase. They can be perceived as two different things depending on which part you see as the figure and which part you see as the background.






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






40. 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.






41. The most famous of all visual illusions. Two horizontal lines of equal length appear unequal because of the orientation of the arrow marks at the end. Inward facing arrow marks make the line appear shorter than another line of the same length with ou






42. The tendency to perceive a smooth motion. This explains why motion is perceived when there is none - often by the use of flashing lights or rapidly shown still-fram pictures - such as in the perception of cartoons. This is apparent motion






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






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






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






46. 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.






47. Along the visual pathway is the...






48. Is the tendency to complete incomplete figures






49. How people perceive objects in the way that they are familiar with them - regardless of changes in the actual retinal image. A book - for example - is perceived as rectangular in shape no matter what angle it is seen from.






50. 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.
