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. Proposed the perceptual development and optic array






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






3. Why do cones see better than rods?






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






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






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


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






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






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






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






11. humans best hear at






12. Along the visual pathway is the...






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






14. 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






15. The way that a single point of light viewed in darkness will appear to shake or move. the reason for this is the movement of our own eyes






16. 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.






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


18. Failing to detect a present stimulus






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






20. 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.






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






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






23. Best at seeing fine details






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






25. 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


26. 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.






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






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






29. Proposed the opponent color/process theory






30. The feeling that results from physical stimulation






31. Is the inability to recognize faces






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






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






34. Has monocular and binocular cues






35. 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






36. 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.






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






38. Rightly stating that no stimulus exists






39. Is the result of regeneration of retinal pigment






40. The physical intensity of light






41. 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






42. Comes from the complexity of the sound wave






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






44. 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'






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






46. Correctly sensing a stimulus






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






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






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






50. We see objects because of the light they reflect
