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. 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.






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






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






4. Located by the cornea






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






6. Consists of the bony labyrinth - a hollow cavity in the temporal bone of the skull with a system of passages comprising two main functional parts: The cochlea - dedicated to hearing; converting sound pressure patterns from the outer ear into electroc






7. Found that infants prefer relatively complex and sensational displays






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






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






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






11. Refers to the relationship between the meaningful part of a picture and the background






12. Best at seeing fine details






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






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






15. Rods and cones on the retina that are responsible for sensory transduction.






16. 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

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






18. The physical intensity of light






19. 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.






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






21. We see objects because of the light they reflect






22. Is the result of regeneration of retinal pigment






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






24. humans best hear at






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






26. 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






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






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






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






30. Why do cones see better than rods?






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






32. Along the visual pathway is the...






33. 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.






34. 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.






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






36. 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.






37. Proposed the opponent color/process theory






38. Has monocular and binocular cues






39. Located in the back of the eye - receives light images from the lens. It is composed of about 30 million photoreceptor cells and of other cell layers that process information






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






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






42. 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






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






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






45. Or overlap of objects shows which objects are closer






46. Proposed the perceptual development and optic array






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. 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






49. Asserts that perception and cognition are largely innate






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