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






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






3. We see objects because of the light they reflect






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






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






6. 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






7. 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.






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






9. Along the visual pathway is the...






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






11. 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






12. 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






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






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. 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. Has monocular and binocular cues






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






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






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. Defined the Just Noticeable Difference






21. Comes from the complexity of the sound wave






22. 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.






23. 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.






24. Is the tendency to make figures out of symmetrical images






25. 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.






26. Saying you detect a stimulus that is not there






27. humans best hear at






28. Correctly sensing a stimulus






29. Found that infants prefer relatively complex and sensational displays






30. Proposed the perceptual development and optic array






31. How we organize or experience sensations






32. Proposed the opponent color/process theory






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






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






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






36. Famous for the theory of color blindness






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






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






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






40. 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.






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






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






43. Why do cones see better than rods?






44. 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.






45. Is the result of regeneration of retinal pigment






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






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






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






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






50. 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'
