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. 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.






2. 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.






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






4. Factors into why we see what we expect to see






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






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






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






8. 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






9. 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






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






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

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






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






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






15. 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.






16. 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.






17. 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'






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






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






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






21. Proposed the opponent color/process theory






22. 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






23. Famous for the theory of color blindness






24. Rightly stating that no stimulus exists






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






26. The physical intensity of light






27. 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.






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






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






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






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






32. 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.






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






34. 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






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






36. Found that infants prefer relatively complex and sensational displays






37. Asserts that perception and cognition are largely innate






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






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






40. 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






41. The feeling that results from physical stimulation






42. 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






43. The chemical that aids the receptor cells in transduction






44. 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






45. Saying you detect a stimulus that is not there






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






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






48. After the optic chasm - information travels to the...






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






50. 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.
