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. 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.






2. 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






3. Located by the cornea






4. Rightly stating that no stimulus exists






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






6. Knowing that an elephant is large no matter how it might appear






7. We see objects because of the light they reflect






8. 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.






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






10. 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.






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






12. 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'






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






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






15. 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






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






17. 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.






18. Defined the Just Noticeable Difference






19. 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






20. Failing to detect a present stimulus






21. The feeling that results from physical stimulation






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






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






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






25. 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.






26. 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






27. The chemical that aids the receptor cells in transduction






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






29. humans best hear at






30. Or overlap of objects shows which objects are closer






31. 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

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






33. Best at seeing fine details






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






35. Correctly sensing a stimulus






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






37. Is the inability to recognize faces






38. Proposed the opponent color/process theory






39. Found that infants prefer relatively complex and sensational displays






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






41. 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.






42. Individuals are partly motivated by rewards and costs in detection. The interplay between response bias and stimulus intensity determines responses






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






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






45. The overarching Gestalt idea that experience will be organized as meaningful - symmetrical - and simple whenever possible.






46. Is the result of regeneration of retinal pigment






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






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






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






50. Asserts that perception is the sum total of sensory input. The world is understood through bottom-up processing
