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. 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






2. 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






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






4. 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






5. 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






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






7. Has monocular and binocular cues






8. Correctly sensing a stimulus






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






10. Or overlap of objects shows which objects are closer






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






12. Begins with the tympanic membrane (eardrum) which is stretch across the auditory canal. Behind this membrane are the Ossicles (3 small bones) - the last of which is the stapes. Sound vibrations bump against the tympanic membrane - causing the ossicl






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






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






15. Proposed the perceptual development and optic array






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






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

18. Is the result of regeneration of retinal pigment






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






20. Located by the cornea






21. 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






22. The physical intensity of light






23. Failing to detect a present stimulus






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






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






26. Defined the Just Noticeable Difference






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






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






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






30. The chemical that aids the receptor cells in transduction






31. 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.






32. Is the inability to recognize faces






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






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

35. We see objects because of the light they reflect






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






37. Saying you detect a stimulus that is not there






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






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






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






41. 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'






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






43. Best at seeing fine details






44. The feeling that results from physical stimulation






45. 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.






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






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






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






49. 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






50. Along the visual pathway is the...
