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






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

3. Is the result of regeneration of retinal pigment






4. We see objects because of the light they reflect






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






6. Why do cones see better than rods?






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






8. Is the tendency to complete incomplete figures






9. 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.






10. humans best hear at






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






12. 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






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






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






15. 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.






16. Best at seeing fine details






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






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






19. Saying you detect a stimulus that is not there






20. The physical intensity of light






21. Comes from the complexity of the sound wave






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






23. 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'






24. Proposed the opponent color/process theory






25. Famous for the theory of color blindness






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






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






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. 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.






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






31. The chemical that aids the receptor cells in transduction






32. Failing to detect a present stimulus






33. Proposed the perceptual development and optic array






34. 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






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






36. 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

37. Rightly stating that no stimulus exists






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






39. 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






40. Found that infants prefer relatively complex and sensational displays






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






42. 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.






43. 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.






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






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






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






48. 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.






49. How we organize or experience sensations






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