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 center of the retina; has the greatest visual acuity






2. The physical intensity of light






3. Are particularly sensitive to dim light and are used for night vision. They are also concentrated along the sides of the retina - making them extremely important for peripheral vision






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






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






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






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






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






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






10. 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.






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






12. 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.






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






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






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






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






18. 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

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






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






21. Has monocular and binocular cues






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






23. 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.






24. Is the result of regeneration of retinal pigment






25. Defined the Just Noticeable Difference






26. Proposed the perceptual development and optic array






27. 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.






28. 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






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






30. The chemical that aids the receptor cells in transduction






31. The moon looks larger when we see it on the horizon than when we see it in the sky. This is because the horizon contains visual cues that make the moon seem more distant than the overhead sky.






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






33. 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.






34. Is the tendency to complete incomplete figures






35. 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.






36. Best at seeing fine details






37. Located by the cornea






38. 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






39. Or overlap of objects shows which objects are closer






40. 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






41. 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






42. 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.






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






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

45. It travels through the horizontal cells to the bipolar cells to the amacrine cells. Finally the information heads to the ganglion cells.






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






47. Is the inability to recognize faces






48. Failing to detect a present stimulus






49. 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






50. Asserts that perception and cognition are largely innate
