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. How we organize or experience sensations






2. 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.






3. 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






4. Why do cones see better than rods?






5. Proposed the opponent color/process theory






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






7. 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.






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






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






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






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






12. The feeling that results from physical stimulation






13. Proposed the perceptual development and optic array






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






15. The chemical that aids the receptor cells in transduction






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






17. 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.






18. 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






19. Failing to detect a present stimulus






20. 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.






21. Famous for the theory of color blindness






22. Asserts that perception and cognition are largely innate






23. 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






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






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






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






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






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






29. 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.






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






31. We see objects because of the light they reflect






32. Comes from the complexity of the sound wave






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






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






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






36. Rightly stating that no stimulus exists






37. 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.






38. Saying you detect a stimulus that is not there






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






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






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






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






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






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






45. 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.






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






47. 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'






48. Is the inability to recognize faces






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






50. 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
