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. 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






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






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






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






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






6. 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






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






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






9. 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'






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






11. We see objects because of the light they reflect






12. Failing to detect a present stimulus






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






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






15. Is the inability to recognize faces






16. Famous for the theory of color blindness






17. 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






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






19. 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






20. Objects that have been drawn and can be perceived but are geometrically impossible






21. Involves both innate/sensory and is partially learned/conceptual






22. Best at seeing fine details






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






24. 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






25. Refers to the relationship between the meaningful part of a picture and the background






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






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

28. Comes from the complexity of the sound wave






29. Why do cones see better than rods?






30. 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.






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






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






33. Or overlap of objects shows which objects are closer






34. The physical intensity of light






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






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






37. 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.






38. Correctly sensing a stimulus






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






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






41. The feeling that results from physical stimulation






42. 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.






43. 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.






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






45. Defined the Just Noticeable Difference






46. Proposed the perceptual development and optic array






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






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

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






50. 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.
