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 complete incomplete figures






2. Located by the cornea






3. 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.






4. 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.






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






6. Or overlap of objects shows which objects are closer






7. 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






8. 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.






9. Defined the Just Noticeable Difference






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






11. 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






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






13. Asserts that perception and cognition are largely innate






14. 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






15. 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






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






17. 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






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






19. Famous for the theory of color blindness






20. The optic nerve is made up of...






21. The chemical that aids the receptor cells in transduction






22. 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.






23. How people perceive objects in the way that they are familiar with them - regardless of changes in the actual retinal image. A book - for example - is perceived as rectangular in shape no matter what angle it is seen from.






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






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






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






27. 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






28. 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






29. 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.






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. Is the result of regeneration of retinal pigment






32. How we organize or experience sensations






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






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






35. Saying you detect a stimulus that is not there






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






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






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






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






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






41. The physical intensity of light






42. Rightly stating that no stimulus exists






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






44. 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'






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






46. Failing to detect a present stimulus






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






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






49. Comes from the complexity of the sound wave






50. Found that infants prefer relatively complex and sensational displays
