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. All the things a person sees trains them to perceive






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






3. 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.






4. 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

5. humans best hear at






6. Found that infants prefer relatively complex and sensational displays






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






8. 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.






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






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






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

12. Rightly stating that no stimulus exists






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






14. The chemical that aids the receptor cells in transduction






15. 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.






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






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






18. Is the tendency to complete incomplete figures






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






20. Along the visual pathway is the...






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






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






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






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






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






26. Correctly sensing a stimulus






27. Why do cones see better than rods?






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






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






30. Has been called the most important depth cue. Our eyes view objects from two slightly different angles - which allows us to create a 3-dimensional figure






31. 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






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






33. The tendency to perceive a smooth motion. This explains why motion is perceived when there is none - often by the use of flashing lights or rapidly shown still-fram pictures - such as in the perception of cartoons. This is apparent motion






34. 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.






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






36. 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






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






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






39. Failing to detect a present stimulus






40. 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.






41. 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.






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






43. 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.






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






45. 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






46. Famous for the theory of color blindness






47. 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






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






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






50. 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
