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. Found that infants prefer relatively complex and sensational displays






2. 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






3. Rightly stating that no stimulus exists






4. 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.






5. Defined the Just Noticeable Difference






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






7. 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






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






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






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






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






12. 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






13. Located by the cornea






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






15. 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.






16. Failing to detect a present stimulus






17. 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.






18. How we organize or experience sensations






19. 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.






20. The chemical that aids the receptor cells in transduction






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






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






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






24. The physical intensity of light






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






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






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






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






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






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






31. 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.






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






33. Asserts that perception and cognition are largely innate






34. Correctly sensing a stimulus






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






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






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






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






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






40. Is the result of regeneration of retinal pigment






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






42. Along the visual pathway is the...






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






44. 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






45. Has monocular and binocular cues






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






47. 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






48. Why do cones see better than rods?






49. 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






50. 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
