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






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






3. 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






4. 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.






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






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






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






8. 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






9. Is the tendency to complete incomplete figures






10. 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.






11. 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.






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


13. 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






14. 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






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






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






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






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






19. Found that infants prefer relatively complex and sensational displays






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






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






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






23. 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.






24. Defined the Just Noticeable Difference






25. How we organize or experience sensations






26. 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.






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






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






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






30. Rightly stating that no stimulus exists






31. Proposed the opponent color/process theory






32. Asserts that perception and cognition are largely innate






33. Saying you detect a stimulus that is not there






34. Why do cones see better than rods?






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


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






37. 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.






38. 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.






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






40. Is the result of regeneration of retinal pigment






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






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






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






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






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






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






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






48. 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






49. The chemical that aids the receptor cells in transduction






50. Proposed the perceptual development and optic array
