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. The physical intensity of light






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






4. 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'






5. Also known as color - is the dominant wavelength of light






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






7. 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






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






9. 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






10. Saying you detect a stimulus that is not there






11. Found that infants prefer relatively complex and sensational displays






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






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






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






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






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






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






19. 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.






20. We see objects because of the light they reflect






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






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






23. Best at seeing fine details






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






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






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






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






28. 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






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






30. Consists of the bony labyrinth - a hollow cavity in the temporal bone of the skull with a system of passages comprising two main functional parts: The cochlea - dedicated to hearing; converting sound pressure patterns from the outer ear into electroc






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






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






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






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






35. Has monocular and binocular cues






36. 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






37. 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.






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






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






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






41. The chemical that aids the receptor cells in transduction






42. 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.






43. Is the result of regeneration of retinal pigment






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






45. 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






46. Is the inability to recognize faces






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






48. 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.






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






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