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. Saying you detect a stimulus that is not there






2. Correctly sensing a stimulus






3. Has monocular and binocular cues






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






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






6. Asserts that perception and cognition are largely innate






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






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. The part of the world that triggers a particular neuron






10. 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.






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






12. Failing to detect a present stimulus






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






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






15. How we organize or experience sensations






16. 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'






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






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






19. 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

20. Found that infants prefer relatively complex and sensational displays






21. Best at seeing fine details






22. 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






23. Discovered that cells in the visual cortex were so complex and specialized that they respond to certain types of stimuli. For example - some cells only respond to vertical lines - whereas some respond to only right angles.






24. A theory for color vision. It suggests that two types of color sensitive cells exist: Cones that respond to blue-yellow colors and cones that respond to red-green. When one color of the cone is stimulated - the other is inhibited.






25. The physical intensity of light






26. 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.






27. Located by the cornea






28. The chemical that aids the receptor cells in transduction






29. Proposed the perceptual development and optic array






30. Why do cones see better than rods?






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






32. 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






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

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






36. Defined the Just Noticeable Difference






37. Rightly stating that no stimulus exists






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






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






40. 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.






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






42. Comes from the complexity of the sound wave






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






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






45. 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






46. 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.






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






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






49. Is the tendency to complete incomplete figures






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