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 by the cornea






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






3. Is the result of regeneration of retinal pigment






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






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






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






7. Asserts that perception and cognition are largely innate






8. Refers to the entire span that can be perceived or detected by the eye at a given moment.






9. 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






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






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






12. The physical intensity of light






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






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






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






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






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






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






19. 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.






20. 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'






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






22. Found that infants prefer relatively complex and sensational displays






23. Correctly sensing a stimulus






24. 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.






25. Rightly stating that no stimulus exists






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






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






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






29. How we organize or experience sensations






30. Is the inability to recognize faces






31. 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.






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






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






34. 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.






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






36. Failing to detect a present stimulus






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






38. 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






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






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






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






42. 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.






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






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






45. Or overlap of objects shows which objects are closer






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






47. 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






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






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






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