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






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






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






4. Comes from the complexity of the sound wave






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






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






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

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






9. Asserts that perception is the sum total of sensory input. The world is understood through bottom-up processing






10. 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






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






12. Proposed the opponent color/process theory






13. 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






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






15. 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.






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






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






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






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






20. 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.






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






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






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






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






25. Or overlap of objects shows which objects are closer






26. Asserts that perception and cognition are largely innate






27. Is knowing the color of an object even with tinted glasses on






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






29. 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.






30. Located by the cornea






31. 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

32. 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






33. Is the inability to recognize faces






34. 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






35. The feeling that results from physical stimulation






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






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






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






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






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






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






42. 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






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

44. How we organize or experience sensations






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






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






47. Best at seeing fine details






48. 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.






49. Correctly sensing a stimulus






50. We see objects because of the light they reflect
