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. Consists of the parts you see called the pinna and the auditory canal. Vibrations from sound move down this canal to the middle ear.






2. The chemical that aids the receptor cells in transduction






3. Is the result of regeneration of retinal pigment






4. Or overlap of objects shows which objects are closer






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






6. Proposed the opponent color/process theory






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






10. Asserts that perception and cognition are largely innate






11. 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






12. 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.






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






14. Comes from the complexity of the sound wave






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






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






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






18. 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






19. 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






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






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






22. 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

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






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






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






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






27. The physical intensity of light






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






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






30. 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






31. 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.






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






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






34. 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






35. 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.






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






37. 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






38. Is the inability to recognize faces






39. Located by the cornea






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






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






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






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






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






45. The part of the world that triggers a particular neuron






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






47. Rightly stating that no stimulus exists






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






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






50. 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.
