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.

1. 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.






2. 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






3. Famous for the theory of color blindness






4. Comes from the complexity of the sound wave






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






6. 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.






7. Found that infants prefer relatively complex and sensational displays






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






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






10. 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.






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






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






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






14. Along the visual pathway is the...






15. How we organize or experience sensations






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






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

18. Is the tendency to complete incomplete figures






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






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






21. Is the result of regeneration of retinal pigment






22. 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






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






24. Asserts that perception and cognition are largely innate






25. Defined the Just Noticeable Difference






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






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






28. 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.






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






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






31. 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'






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






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






34. 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.






35. 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






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






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






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






39. Why do cones see better than rods?






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






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

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






43. Proposed the perceptual development and optic array






44. Best at seeing fine details






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. 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






47. We see objects because of the light they reflect






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






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






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