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. 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






2. 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.






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






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






5. Rightly stating that no stimulus exists






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






7. 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


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






9. 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






10. The physical intensity of light






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






12. 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






13. Saying you detect a stimulus that is not there






14. Is composed of photons and waves measured by brightness and wavelengths






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. A theory for color vision. It suggests that two types of color sensitive cells exist: Cones that respond to blue-yellow colors and cones that respond to red-green. When one color of the cone is stimulated - the other is inhibited.






17. Found that infants prefer relatively complex and sensational displays






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






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






20. Is the tendency to complete incomplete figures






21. We see objects because of the light they reflect






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






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






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






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






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






27. 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






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






29. 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.






30. Comes from the complexity of the sound wave






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






32. The feeling that results from physical stimulation






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






34. humans best hear at






35. 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.






36. 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






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






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






39. Consists of the parts you see called the pinna and the auditory canal. Vibrations from sound move down this canal to the middle ear.






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






41. Failing to detect a present stimulus






42. 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.






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






44. Is the inability to recognize faces






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


46. Is the result of regeneration of retinal pigment






47. 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.






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






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






50. Or overlap of objects shows which objects are closer
