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






2. Proposed the perceptual development and optic array






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






4. Defined the Just Noticeable Difference






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






6. Proposed the opponent color/process theory






7. Asserts that perception and cognition are largely innate






8. Famous for the theory of color blindness






9. The feeling that results from physical stimulation






10. 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.






11. Why do cones see better than rods?






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






13. 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.






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






15. 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






16. 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






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






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






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






20. Is the inability to recognize faces






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






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






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






24. The moon looks larger when we see it on the horizon than when we see it in the sky. This is because the horizon contains visual cues that make the moon seem more distant than the overhead sky.






25. Best at seeing fine details






26. Located by the cornea






27. Comes from the complexity of the sound wave






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






29. 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.






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






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






32. 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






33. Rightly stating that no stimulus exists






34. All the things a person sees trains them to perceive






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






36. 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.






37. humans best hear at






38. The chemical that aids the receptor cells in transduction






39. How we organize or experience sensations






40. Failing to detect a present stimulus






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






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

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






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






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






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






47. 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.






48. Proposed the tri-color theory - research shows that the opponent-process theory seems to be at work in the Lateral geniculate body - research shows that the tri-color theory seems to be at work in the Retina






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






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