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. 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






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






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






4. Located by the cornea






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






6. Or overlap of objects shows which objects are closer






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






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






9. Proposed the perceptual development and optic array






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






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






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






13. Defined the Just Noticeable Difference






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






15. 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






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






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






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






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






20. Asserts that perception and cognition are largely innate






21. 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






22. Why do cones see better than rods?






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






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






25. 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.






26. How we organize or experience sensations






27. Is the inability to recognize faces






28. The feeling that results from physical stimulation






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






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






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






32. The chemical that aids the receptor cells in transduction






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






34. 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






35. We see objects because of the light they reflect






36. 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.






37. Is the result of regeneration of retinal pigment






38. Found that infants prefer relatively complex and sensational displays






39. 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






40. Rightly stating that no stimulus exists






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






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

43. 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






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






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






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






47. 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.






48. 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.






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






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