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. The part of the world that triggers a particular neuron






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






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






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

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






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






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






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






9. Asserts that perception and cognition are largely innate






10. Correctly sensing a stimulus






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






12. Rightly stating that no stimulus exists






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






14. 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.






15. Proposed the perceptual development and optic array






16. 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.






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






18. Proposed the opponent color/process theory






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






20. 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.






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






22. Or overlap of objects shows which objects are closer






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






24. 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






25. Is the inability to recognize faces






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






27. 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.






28. 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






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






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






31. Failing to detect a present stimulus






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






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






34. 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






35. Found that infants prefer relatively complex and sensational displays






36. Is the result of regeneration of retinal pigment






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






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






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






40. 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






41. 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.






42. 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'






43. Best at seeing fine details






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






45. 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.






46. Along the visual pathway is the...






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






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






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. Developed the visual cliff to study whether depth perception was innate
