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. Has been explained as the increasing ability of a child to make finer discriminations among stimuli.






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






3. Rightly stating that no stimulus exists






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






5. 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.






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

Warning: Invalid argument supplied for foreach() in /var/www/html/basicversity.com/show_quiz.php on line 183


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






8. 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'






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






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






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






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. Has monocular and binocular cues






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






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






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






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






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






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






20. Correctly sensing a stimulus






21. 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






22. 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.






23. The physical intensity of light






24. Defined the Just Noticeable Difference






25. humans best hear at






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






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. Proposed the opponent color/process theory






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






30. Asserts that perception and cognition are largely innate






31. 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






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






33. The chemical that aids the receptor cells in transduction






34. 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.






35. 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






36. 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






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






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






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






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






41. Is the inability to recognize faces






42. 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






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






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






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






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






47. How we organize or experience sensations






48. Individuals are partly motivated by rewards and costs in detection. The interplay between response bias and stimulus intensity determines responses






49. 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.






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