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






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






4. How we organize or experience sensations






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






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






7. 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






8. 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.






9. 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.






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






11. 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.






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






13. 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






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






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

16. Or overlap of objects shows which objects are closer






17. Found that infants prefer relatively complex and sensational displays






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






19. 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.






20. Saying you detect a stimulus that is not there






21. 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






22. Failing to detect a present stimulus






23. Located by the cornea






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






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






26. 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






27. Defined the Just Noticeable Difference






28. Asserts that perception and cognition are largely innate






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






30. Is the inability to recognize faces






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






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






33. Correctly sensing a stimulus






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






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






36. Is the tendency to complete incomplete figures






37. We see objects because of the light they reflect






38. The most famous of all visual illusions. Two horizontal lines of equal length appear unequal because of the orientation of the arrow marks at the end. Inward facing arrow marks make the line appear shorter than another line of the same length with ou






39. 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.






40. Best at seeing fine details






41. Has monocular and binocular cues






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






43. 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'






44. 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






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






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






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






48. 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.






49. Proposed the perceptual development and optic array






50. Proposed the opponent color/process theory
