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. Found that infants prefer relatively complex and sensational displays






2. Proposed the opponent color/process theory






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






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






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






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






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






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






9. We see objects because of the light they reflect






10. 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






11. 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






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






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






14. 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.






15. Saying you detect a stimulus that is not there






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






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






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






19. 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.






20. Is the result of regeneration of retinal pigment






21. The physical intensity of light






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






23. 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.






24. Failing to detect a present stimulus






25. 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






26. After images are perceived because of fatigued receptors. Because our eyes have a partially oppositional system for seeing colors - such as red-green or black-white - once on side is overstimulated and fatigued - it can no longer respond and is overs






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






28. 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






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






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






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






32. Asserts that perception is the sum total of sensory input. The world is understood through bottom-up processing






33. How people perceive objects in the way that they are familiar with them - regardless of changes in the actual retinal image. A book - for example - is perceived as rectangular in shape no matter what angle it is seen from.






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






35. 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.






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






37. 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.






38. 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

Warning: Invalid argument supplied for foreach() in /var/www/html/basicversity.com/show_quiz.php on line 183


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






40. Along the visual pathway is the...






41. Or overlap of objects shows which objects are closer






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






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






44. Famous for the theory of color blindness






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






46. Comes from the complexity of the sound wave






47. Proposed the perceptual development and optic array






48. Is the tendency to complete incomplete figures






49. Defined the Just Noticeable Difference






50. humans best hear at
