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. Proposed the opponent color/process theory






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






3. Asserts that perception and cognition are largely innate






4. 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






5. Is the result of regeneration of retinal pigment






6. 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.






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






8. 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.






9. Is the inability to recognize faces






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






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






12. Is the tendency to complete incomplete figures






13. Along the visual pathway is the...






14. 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






15. 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






16. Rightly stating that no stimulus exists






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






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






19. 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






20. 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






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






22. Failing to detect a present stimulus






23. Are concentrated in the center of the retina. They are sensitive to color and daylight vision.






24. 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.






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






26. Defined the Just Noticeable Difference






27. 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

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






29. 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






30. 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






31. Correctly sensing a stimulus






32. The feeling that results from physical stimulation






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






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






35. 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






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






37. Comes from the complexity of the sound wave






38. 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






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






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






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






42. Has monocular and binocular cues






43. 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






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






45. The chemical that aids the receptor cells in transduction






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






47. Or overlap of objects shows which objects are closer






48. 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.






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






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