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. 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.






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






4. The physical intensity of light






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






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






7. The chemical that aids the receptor cells in transduction






8. 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

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






10. 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.






11. 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.






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






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






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






15. 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






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






17. 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.






18. Correctly sensing a stimulus






19. Or overlap of objects shows which objects are closer






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






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






22. 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.






23. 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.






24. Is the result of regeneration of retinal pigment






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






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






27. Comes from the complexity of the sound wave






28. 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






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






30. 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.






31. Is the inability to recognize faces






32. 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






33. Has monocular and binocular cues






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






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






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

37. Found that infants prefer relatively complex and sensational displays






38. Located by the cornea






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






40. Best at seeing fine details






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






42. Saying you detect a stimulus that is not there






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






44. The feeling that results from physical stimulation






45. Proposed the perceptual development and optic array






46. We see objects because of the light they reflect






47. Failing to detect a present stimulus






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






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