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. Comes from the complexity of the sound wave






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






3. Proposed the perceptual development and optic array






4. 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.






5. The feeling that results from physical stimulation






6. 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.






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






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






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






10. 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






11. 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






12. 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






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






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






15. Curces are graphical representations of a subject'S sensitivity to a stimulus






16. Saying you detect a stimulus that is not there






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






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






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






20. Is the result of regeneration of retinal pigment






21. 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






22. 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.






23. Located by the cornea






24. 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.






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






26. Correctly sensing a stimulus






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






28. 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'






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






30. Best at seeing fine details






31. We see objects because of the light they reflect






32. Rightly stating that no stimulus exists






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






34. The chemical that aids the receptor cells in transduction






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






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

37. Why do cones see better than rods?






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






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






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






41. 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






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






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






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






45. Asserts that perception and cognition are largely innate






46. 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.






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






48. Found that infants prefer relatively complex and sensational displays






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






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