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. Proposed the perceptual development and optic array






2. Has monocular and binocular cues






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






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






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






6. 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






7. Asserts that perception and cognition are largely innate






8. 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






9. 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.






10. 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






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






12. Failing to detect a present stimulus






13. 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






14. 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






15. Why do cones see better than rods?






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






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






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






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






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






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






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






23. 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.






24. Found that infants prefer relatively complex and sensational displays






25. 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






26. Correctly sensing a stimulus






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






28. 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.






29. How we organize or experience sensations






30. The chemical that aids the receptor cells in transduction






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






32. 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.






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






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






35. 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






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






37. 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.






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






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






40. 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.






41. Comes from the complexity of the sound wave






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






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






44. Defined the Just Noticeable Difference






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






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






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






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






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






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