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






2. Famous for the theory of color blindness






3. Discovered that cells in the visual cortex were so complex and specialized that they respond to certain types of stimuli. For example - some cells only respond to vertical lines - whereas some respond to only right angles.






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






5. Rightly stating that no stimulus exists






6. 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






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






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






9. Is the way that perceived color brightness changes with the level of illumination in the room. With lower levels of illumination - the extremes of the color spectrum (especially red) are seen as less bright






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






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






12. 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.






13. Correctly sensing a stimulus






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






15. Proposed the perceptual development and optic array






16. Asserts that perception and cognition are largely innate






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






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






19. 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






20. Defined the Just Noticeable Difference






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






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






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






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






25. humans best hear at






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






27. 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






28. Why do cones see better than rods?






29. We see objects because of the light they reflect






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






31. 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.






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






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






34. Along the visual pathway is the...






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






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






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






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


39. Also known as just noticeable difference. The minimum difference that must occur between two stimuli - in order for them to be perceived as having different intensities.






40. 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






41. The physical intensity of light






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






43. 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.






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






45. Or overlap of objects shows which objects are closer






46. 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.






47. The chemical that aids the receptor cells in transduction






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






49. 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






50. Comes from the complexity of the sound wave
