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






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






3. 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






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






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






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






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






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






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






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

11. Proposed the perceptual development and optic array






12. We see objects because of the light they reflect






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






14. 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






15. Failing to detect a present stimulus






16. 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






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






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






19. 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.






20. Defined the Just Noticeable Difference






21. Why do cones see better than rods?






22. 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






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






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






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






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






27. Rightly stating that no stimulus exists






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






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






30. 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.






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






32. 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.






33. Saying you detect a stimulus that is not there






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






35. Asserts that perception and cognition are largely innate






36. Is the tendency to complete incomplete figures






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






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






39. 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






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






41. Is the result of regeneration of retinal pigment






42. Correctly sensing a stimulus






43. 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






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






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

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






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






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






49. The physical intensity of light






50. Has monocular and binocular cues
