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. Along the visual pathway is the...






2. 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.






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






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






5. After the optic chasm - information travels to the...






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






7. 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






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






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






10. 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.






11. Saying you detect a stimulus that is not there






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






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






14. 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.






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






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






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






18. Is the result of regeneration of retinal pigment






19. Best at seeing fine details






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






21. Proposed the opponent color/process theory






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






23. 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.






24. Is the minimum amount of stimuli that can be detected 50% of the time






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






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






27. 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






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






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






30. 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'






31. Has monocular and binocular cues






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






33. The center of the retina; has the greatest visual acuity






34. Is the tendency to complete incomplete figures






35. Found that infants prefer relatively complex and sensational displays






36. 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


37. How we organize or experience sensations






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






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






40. 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






41. humans best hear at






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






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






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






45. 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.






46. Is the inability to recognize faces






47. Famous for the theory of color blindness






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






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






50. 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
