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. 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.






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






3. The chemical that aids the receptor cells in transduction






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






5. Is the result of regeneration of retinal pigment






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






7. 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






8. 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.






9. Comes from the complexity of the sound wave






10. Asserts that perception and cognition are largely innate






11. Is the tendency to complete incomplete figures






12. Defined the Just Noticeable Difference






13. Takes place when receptors for a particular sense detect a stimulus.






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

15. 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






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






17. Or overlap of objects shows which objects are closer






18. The physical intensity of light






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






20. Saying you detect a stimulus that is not there






21. 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






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






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






24. Located by the cornea






25. 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






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






27. How we organize or experience sensations






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






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






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






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






32. 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'






33. Along the visual pathway is the...






34. Failing to detect a present stimulus






35. 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.






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






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






38. 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






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






40. Best at seeing fine details






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

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






43. 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.






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






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






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






47. 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






48. Found that infants prefer relatively complex and sensational displays






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






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