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. 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

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






3. 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






4. 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






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






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






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






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






9. The physical intensity of light






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






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






13. 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.






14. Located by the cornea






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






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






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






18. 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.






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






20. Asserts that perception and cognition are largely innate






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






22. 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






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






24. Saying you detect a stimulus that is not there






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






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






27. 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






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






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






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






31. Begins with the tympanic membrane (eardrum) which is stretch across the auditory canal. Behind this membrane are the Ossicles (3 small bones) - the last of which is the stapes. Sound vibrations bump against the tympanic membrane - causing the ossicl






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






33. The feeling that results from physical stimulation






34. 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.






35. Has monocular and binocular cues






36. 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.






37. Or overlap of objects shows which objects are closer






38. Takes place when receptors for a particular sense detect a stimulus.






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






40. Comes from the complexity of the sound wave






41. How we organize or experience sensations






42. 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'






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






44. Says that the strength of a stimulus must be significantly increased to produce a slight difference in sensation

45. Is the result of regeneration of retinal pigment






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






47. Found that infants prefer relatively complex and sensational displays






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






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






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