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






2. 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.






3. How people perceive objects in the way that they are familiar with them - regardless of changes in the actual retinal image. A book - for example - is perceived as rectangular in shape no matter what angle it is seen from.






4. Or overlap of objects shows which objects are closer






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






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






7. Comes from the complexity of the sound wave






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






9. 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.






10. Is the tendency to complete incomplete figures






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






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






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






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






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






16. Correctly sensing a stimulus






17. 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






18. 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






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






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






21. 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.






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






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






24. 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.






25. Famous for the theory of color blindness






26. 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






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

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






29. 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






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






31. Saying you detect a stimulus that is not there






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

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






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






35. How we organize or experience sensations






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






37. 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.






38. Asserts that perception and cognition are largely innate






39. 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

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






41. 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






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






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






44. The physical intensity of light






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






46. Located by the cornea






47. Best at seeing fine details






48. Is the result of regeneration of retinal pigment






49. Proposed the perceptual development and optic array
