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 result of regeneration of retinal pigment






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






3. Asserts that perception and cognition are largely innate






4. 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






5. Proposed the opponent color/process theory






6. Rightly stating that no stimulus exists






7. 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






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






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






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






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






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






13. The feeling that results from physical stimulation






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






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






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






17. Located by the cornea






18. Found that infants prefer relatively complex and sensational displays






19. 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






20. 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.






21. 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






22. humans best hear at






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






24. 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

25. Proposed the perceptual development and optic array






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






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






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






29. The chemical that aids the receptor cells in transduction






30. We see objects because of the light they reflect






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






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






33. 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.






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






35. Saying you detect a stimulus that is not there






36. Defined the Just Noticeable Difference






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






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






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






40. Failing to detect a present stimulus






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






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






43. 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






44. 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






45. 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.






46. 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.






47. 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.






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






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

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