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. humans best hear at






2. Failing to detect a present stimulus






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






4. Electrical impulses travel down these to the brain - where the information is understood






5. How we organize or experience sensations






6. Located by the cornea






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






8. Defined the Just Noticeable Difference






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






10. 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






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

12. 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.






13. 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.






14. Asserts that perception and cognition are largely innate






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






16. Best at seeing fine details






17. 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.






18. Has monocular and binocular cues






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






20. Why do cones see better than rods?






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






22. Or overlap of objects shows which objects are closer






23. Comes from the complexity of the sound wave






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






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






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






27. 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






28. 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.






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






30. 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.






31. 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






32. Applies to all senses but only to a limited range of intensities. The law states that a stimulus needs to be increased by a constant fraction of its original value in order to be noticeably different

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






34. Famous for the theory of color blindness






35. 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






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






37. 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






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






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






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






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






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






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






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






45. 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.






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






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






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






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






50. Rightly stating that no stimulus exists
