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






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






3. Asserts that perception and cognition are largely innate






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






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






6. 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






7. Rightly stating that no stimulus exists






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






9. Has monocular and binocular cues






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






11. The feeling that results from physical stimulation






12. humans best hear at






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






14. 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


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






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






17. 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






18. 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.






19. Along the visual pathway is the...






20. Proposed the opponent color/process theory






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






22. 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.






23. We see objects because of the light they reflect






24. Correctly sensing a stimulus






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






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






27. 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.






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






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






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






31. 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.






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






33. The center of the retina; has the greatest visual acuity






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






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






36. 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.






37. It travels through the horizontal cells to the bipolar cells to the amacrine cells. Finally the information heads to the ganglion cells.






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






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






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






41. 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






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






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






44. 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






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






46. The physical intensity of light






47. The chemical that aids the receptor cells in transduction






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






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






50. Famous for the theory of color blindness
