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






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






3. 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.






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






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


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






7. 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






8. Failing to detect a present stimulus






9. 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.






10. humans best hear at






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






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






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






14. 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'






15. The feeling that results from physical stimulation






16. 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






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






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






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






20. 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


21. Best at seeing fine details






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






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






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






25. Has monocular and binocular cues






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






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






28. Asserts that perception and cognition are largely innate






29. Correctly sensing a stimulus






30. How we organize or experience sensations






31. Proposed the perceptual development and optic array






32. Comes from the complexity of the sound wave






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






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






35. Proposed the opponent color/process theory






36. 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






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






38. 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






39. 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.






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. Or overlap of objects shows which objects are closer






42. Why do cones see better than rods?






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






44. 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.






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






46. Found that infants prefer relatively complex and sensational displays






47. 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






48. 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.






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






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