GRE Psychology: Perception Sensation

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






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

3. The feeling that results from physical stimulation






4. Proposed the perceptual development and optic array






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






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






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






8. 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






9. 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.






10. Is the inability to recognize faces






11. Or overlap of objects shows which objects are closer






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






13. The chemical that aids the receptor cells in transduction






14. Saying you detect a stimulus that is not there






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






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






17. Correctly sensing a stimulus






18. 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.






19. 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






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






21. Found that infants prefer relatively complex and sensational displays






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






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






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






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






26. Comes from the complexity of the sound wave






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






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






29. 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






30. Located by the cornea






31. 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






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






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






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






35. Is the result of regeneration of retinal pigment






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






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






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






39. 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






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






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






42. 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






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






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






45. 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






46. Failing to detect a present stimulus






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






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






49. 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






50. Along the visual pathway is the...
