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. 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






2. The physical intensity of light






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






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






5. 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.






6. Rightly stating that no stimulus exists






7. 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






8. 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.






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






10. 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.






11. 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






12. Why do cones see better than rods?






13. Famous for the theory of color blindness






14. Is the tendency to complete incomplete figures






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






16. Found that infants prefer relatively complex and sensational displays






17. Is the inability to recognize faces






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






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






20. Is the result of regeneration of retinal pigment






21. 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.






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






23. Where half of all fibers from the optic nerve of each eye cross over and join the optic nerve from the other eye. This insures input from each eye will be put together in a full picture in the brain.






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






25. The feeling that results from physical stimulation






26. Consists of the parts you see called the pinna and the auditory canal. Vibrations from sound move down this canal to the middle ear.






27. Located by the cornea






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






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






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






31. 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






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






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






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. 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






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






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






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






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






40. Has monocular and binocular cues






41. Best at seeing fine details






42. 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.






43. Saying you detect a stimulus that is not there






44. Asserts that perception and cognition are largely innate






45. Proposed the opponent color/process theory






46. Failing to detect a present stimulus






47. Comes from the complexity of the sound wave






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






49. We see objects because of the light they reflect






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