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






3. 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






4. 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'






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






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






7. Located by the cornea






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






9. Proposed the perceptual development and optic array






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






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






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






13. Rightly stating that no stimulus exists






14. 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.






15. humans best hear at






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






17. Found that infants prefer relatively complex and sensational displays






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






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






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






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






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






23. 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.






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






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






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






27. Has monocular and binocular cues






28. 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






29. 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






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






31. Is the result of regeneration of retinal pigment






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






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






34. The feeling that results from physical stimulation






35. 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.






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






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






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

Warning: Invalid argument supplied for foreach() in /var/www/html/basicversity.com/show_quiz.php on line 183


39. We see objects because of the light they reflect






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






41. Correctly sensing a stimulus






42. Or overlap of objects shows which objects are closer






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






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






45. Best at seeing fine details






46. 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






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






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






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






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