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 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






2. 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






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






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






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






6. 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.






7. 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






8. Is the inability to recognize faces






9. Defined the Just Noticeable Difference






10. Comes from the complexity of the sound wave






11. Or overlap of objects shows which objects are closer






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






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






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






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






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






17. 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.






18. 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.






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






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






21. Best at seeing fine details






22. 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






23. Located by the cornea






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






25. Famous for the theory of color blindness






26. Saying you detect a stimulus that is not there






27. Along the visual pathway is the...






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






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






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






31. Is knowing the color of an object even with tinted glasses on






32. 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






33. 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


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






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






36. Is the tendency to complete incomplete figures






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






38. Proposed the opponent color/process theory






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






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






41. 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.






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






43. How we organize or experience sensations






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






45. We see objects because of the light they reflect






46. Correctly sensing a stimulus






47. 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.






48. Failing to detect a present stimulus






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






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