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 feeling that results from physical stimulation






2. The physical intensity of light






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






4. Gives us clues about how far away an object is if we know about how big the object should be






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

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






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






8. Located by the cornea






9. 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.






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






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






12. 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






13. 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.






14. 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

15. 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






16. 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.






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






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






19. 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






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






21. 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.






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






23. 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.






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






25. 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.






26. Failing to detect a present stimulus






27. How we organize or experience sensations






28. 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






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






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






31. Is the tendency to complete incomplete figures






32. Famous for the theory of color blindness






33. Along the visual pathway is the...






34. 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






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






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






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






38. Is the inability to recognize faces






39. 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.






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






41. Proposed the perceptual development and optic array






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






43. 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






44. The chemical that aids the receptor cells in transduction






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






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






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






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






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






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