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. All the things a person sees trains them to perceive






2. Can be perceived as two different things depending on how you look at them






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






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






5. 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.






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


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






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






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






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






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






12. 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.






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






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






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






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






17. Defined the Just Noticeable Difference






18. Is the result of regeneration of retinal pigment






19. 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






20. 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






21. Comes from the complexity of the sound wave






22. Found that infants prefer relatively complex and sensational displays






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






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






25. The feeling that results from physical stimulation






26. Is the tendency to complete incomplete figures






27. 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.






28. 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.






29. Along the visual pathway is the...






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






31. 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






32. humans best hear at






33. 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






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






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






36. Proposed the perceptual development and optic array






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






38. 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.






39. 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






40. 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






41. Proposed the opponent color/process theory






42. Rightly stating that no stimulus exists






43. How we organize or experience sensations






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






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






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






47. Located by the cornea






48. Correctly sensing a stimulus






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






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