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. 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.






2. Comes from the complexity of the sound wave






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






4. We see objects because of the light they reflect






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






6. 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






7. 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.






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

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






10. How we organize or experience sensations






11. 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






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






13. Along the visual pathway is the...






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






15. 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.






16. 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






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






18. Saying you detect a stimulus that is not there






19. Is the tendency to complete incomplete figures






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






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






22. 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.






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






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






25. Found that infants prefer relatively complex and sensational displays






26. Failing to detect a present stimulus






27. 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






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






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






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






31. The feeling that results from physical stimulation






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






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






34. Is the tendency to create a whole or detailed figure based on our expectations rather than what is seen






35. Famous for the theory of color blindness






36. humans best hear at






37. Is the result of regeneration of retinal pigment






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






39. 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.






40. 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






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






42. 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.






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






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






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






46. 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






47. Defined the Just Noticeable Difference






48. Is the inability to recognize faces






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






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