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. humans best hear at






2. 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






3. Is the inability to recognize faces






4. 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






5. 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.






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






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






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






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






10. Located by the cornea






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






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






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






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






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






16. Along the visual pathway is the...






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






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






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






20. How we organize or experience sensations






21. 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






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






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






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






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






26. Rightly stating that no stimulus exists






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






28. 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.






29. 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






30. We see objects because of the light they reflect






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






32. The chemical that aids the receptor cells in transduction






33. 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.






34. Defined the Just Noticeable Difference






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






36. 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






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






38. 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.






39. Proposed the perceptual development and optic array






40. Is the tendency to complete incomplete figures






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






42. 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


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






44. Has monocular and binocular cues






45. The feeling that results from physical stimulation






46. Saying you detect a stimulus that is not there






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






48. 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.






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






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