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






3. 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.






4. The optic nerve is made up of...






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






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






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






8. 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.






9. Rightly stating that no stimulus exists






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






11. Comes from the complexity of the sound wave






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






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






14. 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






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

16. 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






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






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

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






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






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






22. Is the tendency to complete incomplete figures






23. Is the result of regeneration of retinal pigment






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






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






26. 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.






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






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






30. 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






31. Or overlap of objects shows which objects are closer






32. How we organize or experience sensations






33. Proposed the opponent color/process theory






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






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






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






37. We see objects because of the light they reflect






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






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






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






41. Defined the Just Noticeable Difference






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






43. Is the inability to recognize faces






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






45. Found that infants prefer relatively complex and sensational displays






46. Proposed the perceptual development and optic array






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






48. Famous for the theory of color blindness






49. 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.






50. Saying you detect a stimulus that is not there
