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






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






3. 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

4. Proposed the opponent color/process theory






5. The chemical that aids the receptor cells in transduction






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






7. Defined the Just Noticeable Difference






8. Has monocular and binocular cues






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






10. 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






11. Saying you detect a stimulus that is not there






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






13. Best at seeing fine details






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






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






16. The feeling that results from physical stimulation






17. 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'






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






19. 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.






20. Rightly stating that no stimulus exists






21. Proposed the perceptual development and optic array






22. Why do cones see better than rods?






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






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






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






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






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






28. 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






29. 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






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

31. 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






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






33. humans best hear at






34. Also known as just noticeable difference. The minimum difference that must occur between two stimuli - in order for them to be perceived as having different intensities.






35. 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.






36. 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






37. Is the inability to recognize faces






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






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






40. We see objects because of the light they reflect






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






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






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






44. Located by the cornea






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






46. Correctly sensing a stimulus






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






48. Is the tendency to complete incomplete figures






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






50. Asserts that perception and cognition are largely innate
