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. Along the visual pathway is the...






2. Proposed the perceptual development and optic array






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






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






5. 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






6. 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.






7. Has monocular and binocular cues






8. 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.






9. Correctly sensing a stimulus






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






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






12. humans best hear at






13. Why do cones see better than rods?






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






15. 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.






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






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






18. 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.






19. Asserts that perception and cognition are largely innate






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






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






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






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






24. Found that infants prefer relatively complex and sensational displays






25. Is the tendency to complete incomplete figures






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






27. Best at seeing fine details






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






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






30. Is the inability to recognize faces






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






32. Defined the Just Noticeable Difference






33. 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






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






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






36. The physical intensity of light






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






38. 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






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

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






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






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






43. Comes from the complexity of the sound wave






44. 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






45. 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'






46. 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

47. 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






48. 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.






49. The chemical that aids the receptor cells in transduction






50. 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.
