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






3. 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






4. 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






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






6. 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






7. Best at seeing fine details






8. humans best hear at






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






10. Proposed the opponent color/process theory






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






12. 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.






13. 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






14. 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.






15. 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






16. Correctly sensing a stimulus






17. Failing to detect a present stimulus






18. 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.






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






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






21. 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.






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






23. Saying you detect a stimulus that is not there






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






25. Comes from the complexity of the sound wave






26. 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.






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






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






29. 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.






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






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






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






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






34. 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






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






36. 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

37. 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'






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






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






40. Or overlap of objects shows which objects are closer






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






42. Rightly stating that no stimulus exists






43. Along the visual pathway is the...






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






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






46. The physical intensity of light






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






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






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






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