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 tendency to make figures out of symmetrical images






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






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






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






5. 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






6. 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.






7. Located by the cornea






8. 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






9. 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






10. 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






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






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






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






14. humans best hear at






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






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






17. 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.






18. 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'






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






20. Saying you detect a stimulus that is not there






21. Is the inability to recognize faces






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






23. Proposed the perceptual development and optic array






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






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






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






29. 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






30. Proposed the opponent color/process theory






31. Or overlap of objects shows which objects are closer






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






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






34. Suggests that subjects detect stimuli not only because they can but also because they want to. TSD factors motivation into the picture.

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






36. Is the result of regeneration of retinal pigment






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






38. How movement is perceived though the displacement of objects over time - and how this motion takes place at seemingly different paces for nearby or faraway objects. Ships far away seem to move more slowly than ships moving at the same speed.






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






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






41. 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






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






43. The chemical that aids the receptor cells in transduction






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






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






46. 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






47. 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.






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






49. The physical intensity of light






50. The eyes are connected to the cerebral cortex by...
