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 tendency to make figures out of symmetrical images






2. How we organize or experience sensations






3. The eyes are connected to the cerebral cortex by...






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






5. Found that infants prefer relatively complex and sensational displays






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






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






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






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






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






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


12. 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






13. 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






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






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






16. 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.






17. Is the tendency to complete incomplete figures






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






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






20. Proposed the perceptual development and optic array






21. 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.






22. Along the visual pathway is the...






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






24. Is the result of regeneration of retinal pigment






25. Failing to detect a present stimulus






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






27. 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


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






29. Is the inability to recognize faces






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






31. We see objects because of the light they reflect






32. Saying you detect a stimulus that is not there






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






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






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






36. Rightly stating that no stimulus exists






37. 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.






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






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






40. 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






41. 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'






42. humans best hear at






43. 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.






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






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






46. 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.






47. 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






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






49. The chemical that aids the receptor cells in transduction






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