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






2. Gives us clues about how far away an object is if we know about how big the object should be






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






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






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

6. 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.






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






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






9. Proposed the perceptual development and optic array






10. Located by the cornea






11. 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






12. Is the inability to recognize faces






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

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. Found that infants prefer relatively complex and sensational displays






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






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






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






19. Defined the Just Noticeable Difference






20. Is the result of regeneration of retinal pigment






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






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






23. humans best hear at






24. The physical intensity of light






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






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






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






28. Asserts that perception and cognition are largely innate






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






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






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






32. Has monocular and binocular cues






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






34. 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






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






36. Famous for the theory of color blindness






37. 1. closure 2. Proximity 3. Continuation or good continuation 4. Symmetry 5. Constancy 6. Minimum principle






38. Applies to all senses but only to a limited range of intensities. The law states that a stimulus needs to be increased by a constant fraction of its original value in order to be noticeably different

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






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






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






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






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






44. Best at seeing fine details






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






46. The feeling that results from physical stimulation






47. We see objects because of the light they reflect






48. How we organize or experience sensations






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. 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
