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. Asserts that perception and cognition are largely innate






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






3. Correctly sensing a stimulus






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






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






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






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






8. 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.






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






10. Located by the cornea






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






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






13. Rightly stating that no stimulus exists






14. humans best hear at






15. 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.






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






17. The feeling that results from physical stimulation






18. Along the visual pathway is the...






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






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






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






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






23. 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






24. Proposed the opponent color/process theory






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






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






27. Failing to detect a present stimulus






28. 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.






29. 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






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






31. 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






32. 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






33. How we organize or experience sensations






34. Found that infants prefer relatively complex and sensational displays






35. The way that a single point of light viewed in darkness will appear to shake or move. the reason for this is the movement of our own eyes






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






37. 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






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






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






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

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






42. Defined the Just Noticeable Difference






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






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






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






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






47. Famous for the theory of color blindness






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






49. Or overlap of objects shows which objects are closer






50. 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
