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. 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.






2. Best at seeing fine details






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






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






5. 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






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






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






8. 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






9. Or overlap of objects shows which objects are closer






10. 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

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






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






13. 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






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






15. 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.






16. Along the visual pathway is the...






17. humans best hear at






18. 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.






19. Correctly sensing a stimulus






20. Has monocular and binocular cues






21. The physical intensity of light






22. Why do cones see better than rods?






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






24. The feeling that results from physical stimulation






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






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






27. Asserts that perception and cognition are largely innate






28. Comes from the complexity of the sound wave






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






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






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






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






34. 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






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






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






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






38. 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






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






40. 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.






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






42. The chemical that aids the receptor cells in transduction






43. Is the tendency to complete incomplete figures






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






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






46. Failing to detect a present stimulus






47. Also known as color - is the dominant wavelength of light






48. 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






49. We see objects because of the light they reflect






50. 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.
