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. 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






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






3. Best at seeing fine details






4. 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






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






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






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






8. Famous for the theory of color blindness






9. 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






10. The chemical that aids the receptor cells in transduction






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






12. Is the tendency to complete incomplete figures






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






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






15. Comes from the complexity of the sound wave






16. Has monocular and binocular cues






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






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






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






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






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






22. Asserts that perception is the sum total of sensory input. The world is understood through bottom-up processing






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






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






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






26. 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






27. The physical intensity of light






28. Proposed the perceptual development and optic array






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






30. Is the inability to recognize faces






31. Says that the strength of a stimulus must be significantly increased to produce a slight difference in sensation

32. We see objects because of the light they reflect






33. 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






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






35. 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.






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






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






38. Rightly stating that no stimulus exists






39. Correctly sensing a stimulus






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






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






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






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






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






45. Found that infants prefer relatively complex and sensational displays






46. 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.






47. 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

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






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






50. Asserts that perception and cognition are largely innate
