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. Or overlap of objects shows which objects are closer






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. Famous for the theory of color blindness






4. 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






5. The feeling that results from physical stimulation






6. 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.






7. Is the inability to recognize faces






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






9. Is the result of regeneration of retinal pigment






10. Rods and cones on the retina that are responsible for sensory transduction.






11. Defined the Just Noticeable Difference






12. 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.






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






14. 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






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






16. Why do cones see better than rods?






17. Comes from the complexity of the sound wave






18. humans best hear at






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






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






21. 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'






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. The part of the world that triggers a particular neuron






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






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






26. We see objects because of the light they reflect






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






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






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






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






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






32. Revolves around perception and asserts that people tend to see the world as comprised of organized wholes. The world is understood through top-down processing.






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






34. Proposed the perceptual development and optic array






35. Found that infants prefer relatively complex and sensational displays






36. Saying you detect a stimulus that is not there






37. Correctly sensing a stimulus






38. 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






39. Proposed the opponent color/process theory






40. 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






41. Has monocular and binocular cues






42. Best at seeing fine details






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






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






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






46. 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.






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






48. 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






49. 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.






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