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. Correctly sensing a stimulus






2. Along the visual pathway is the...






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






4. 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.






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






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






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






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






10. Failing to detect a present stimulus






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






12. The feeling that results from physical stimulation






13. 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






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






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






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


18. Asserts that perception and cognition are largely innate






19. A thick layer of glass above a surface that dropped off sharply. The glass provided solid - level ground doe subjects to move across in spite of the cliff below. Animals and babies were used as subjects and both groups avoided moving into the 'cliff'






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






21. We see objects because of the light they reflect






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






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






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






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






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






27. Is the way that perceived color brightness changes with the level of illumination in the room. With lower levels of illumination - the extremes of the color spectrum (especially red) are seen as less bright






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






29. Is the inability to recognize faces






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






31. 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






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






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






34. 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.






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






36. 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


37. 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.






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






39. Why do cones see better than rods?






40. 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






41. Or overlap of objects shows which objects are closer






42. Famous for the theory of color blindness






43. Has monocular and binocular cues






44. The chemical that aids the receptor cells in transduction






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






46. Proposed the perceptual development and optic array






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






48. Defined the Just Noticeable Difference






49. 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.






50. Best at seeing fine details
