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. 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






2. Failing to detect a present stimulus






3. 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






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






5. The physical intensity of light






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






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






8. 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






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






10. Famous for the theory of color blindness






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






12. 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.






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






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






15. Or overlap of objects shows which objects are closer






16. The part of the world that triggers a particular neuron






17. How we organize or experience sensations






18. 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






19. Asserts that perception and cognition are largely innate






20. The clear protective coating on the outside of the eye






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






22. 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






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






24. Rightly stating that no stimulus exists






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






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






27. 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






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






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






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






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


33. Proposed the opponent color/process theory






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






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






36. Is the tendency to complete incomplete figures






37. Along the visual pathway is the...






38. 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






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






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






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






42. Is the result of regeneration of retinal pigment






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






44. Gives us clues about how far away an object is if we know about how big the object should be






45. 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.






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






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






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






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






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