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






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






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






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






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






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






7. Defined the Just Noticeable Difference






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






9. 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.






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






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






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






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






14. Correctly sensing a stimulus






15. Proposed the perceptual development and optic array






16. Along the visual pathway is the...






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

18. Best at seeing fine details






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






20. 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






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






22. The chemical that aids the receptor cells in transduction






23. Has monocular and binocular cues






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






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






26. Proposed the opponent color/process theory






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






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






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






30. 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.






31. 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






32. Is the result of regeneration of retinal pigment






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






34. Rightly stating that no stimulus exists






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






36. 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






37. 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






38. Is the tendency to complete incomplete figures






39. 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.






40. Located by the cornea






41. 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






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






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






44. We see objects because of the light they reflect






45. Comes from the complexity of the sound wave






46. 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.






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






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

49. humans best hear at






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