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






2. The chemical that aids the receptor cells in transduction






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






4. Comes from the complexity of the sound wave






5. Or overlap of objects shows which objects are closer






6. The physical intensity of light






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






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






9. 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






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






11. Best at seeing fine details






12. 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.






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






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






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






16. Asserts that perception and cognition are largely innate






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






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






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






20. 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






21. 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.






22. 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






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






24. 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






25. Rightly stating that no stimulus exists






26. Found that infants prefer relatively complex and sensational displays






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






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






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






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






31. 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






32. After the optic chasm - information travels to the...






33. 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.






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

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






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

37. Proposed the opponent color/process theory






38. 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.






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






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






41. Why do cones see better than rods?






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






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






44. Asserts that perception is the sum total of sensory input. The world is understood through bottom-up processing






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






46. humans best hear at






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






48. A thick layer of glass above a surface that dropped off sharply. The glass provided solid - level ground doe subjects to move across in spite of the cliff below. Animals and babies were used as subjects and both groups avoided moving into the 'cliff'






49. 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






50. 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
