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






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






3. Failing to detect a present stimulus






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






5. We see objects because of the light they reflect






6. 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.






7. Saying you detect a stimulus that is not there






8. 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






9. 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






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






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






12. Has monocular and binocular cues






13. 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.






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






15. Proposed the perceptual development and optic array






16. 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.






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

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






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






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






21. Asserts that perception and cognition are largely innate






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






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






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






25. 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






26. Defined the Just Noticeable Difference






27. The way that a single point of light viewed in darkness will appear to shake or move. the reason for this is the movement of our own eyes






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






29. 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






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






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






32. The chemical that aids the receptor cells in transduction






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






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






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






36. 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.






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






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






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






40. 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.






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






42. Found that infants prefer relatively complex and sensational displays






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






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






45. 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.






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






47. Is the tendency to complete incomplete figures






48. Why do cones see better than rods?






49. 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






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