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






2. 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






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






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






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






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






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






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






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






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






11. The chemical that aids the receptor cells in transduction






12. 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






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






14. Why do cones see better than rods?






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






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






17. Or overlap of objects shows which objects are closer






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






19. Asserts that perception and cognition are largely innate






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






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






22. 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






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






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






25. 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.






26. Is the inability to recognize faces






27. Located by the cornea






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






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. 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.






31. 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.






32. Along the visual pathway is the...






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






34. Is the tendency to complete incomplete figures






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






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






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






38. Electrical impulses travel down these to the brain - where the information is understood






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






40. 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.






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






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

43. Found that infants prefer relatively complex and sensational displays






44. Saying you detect a stimulus that is not there






45. Rightly stating that no stimulus exists






46. Defined the Just Noticeable Difference






47. 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.






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






49. Is the result of regeneration of retinal pigment






50. 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
