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. Why do cones see better than rods?






2. He tendency to group together items that are near each other






3. 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.






4. 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.






5. 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.






6. Defined the Just Noticeable Difference






7. We see objects because of the light they reflect






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






9. Correctly sensing a stimulus






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






11. How we organize or experience sensations






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






13. 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






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






15. 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






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






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






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






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






20. 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






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






22. 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






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






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






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






26. Found that infants prefer relatively complex and sensational displays






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






28. 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.






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






30. Proposed the perceptual development and optic array






31. 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






32. Best at seeing fine details






33. The physical intensity of light






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






35. The feeling that results from physical stimulation






36. Comes from the complexity of the sound wave






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






38. 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.






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






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






41. The chemical that aids the receptor cells in transduction






42. 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.






43. 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






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






45. Along the visual pathway is the...






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






47. Is the tendency to complete incomplete figures






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






49. humans best hear at






50. Knowing that an elephant is large no matter how it might appear
