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. 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.






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






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


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






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






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






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






8. 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'






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






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






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






12. 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.






13. 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






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






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






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






17. The chemical that aids the receptor cells in transduction






18. The feeling that results from physical stimulation






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






20. 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.






21. 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






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






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






24. humans best hear at






25. Comes from the complexity of the sound wave






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






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






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






29. Found that infants prefer relatively complex and sensational displays






30. 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






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






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






33. 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.






34. Best at seeing fine details






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






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






37. Has monocular and binocular cues






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






39. Or overlap of objects shows which objects are closer






40. Proposed the opponent color/process theory






41. 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


42. 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.






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






45. Says that the strength of a stimulus must be significantly increased to produce a slight difference in sensation


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






47. Rightly stating that no stimulus exists






48. Famous for the theory of color blindness






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






50. 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
