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






2. 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






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






4. Located by the cornea






5. Found that infants prefer relatively complex and sensational displays






6. 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.






7. 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






8. 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.






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






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






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






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






13. 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'






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






15. Is the result of regeneration of retinal pigment






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






17. 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.






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






19. 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.






20. Asserts that perception and cognition are largely innate






21. Proposed the opponent color/process theory






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






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






24. Correctly sensing a stimulus






25. humans best hear at






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






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






28. Failing to detect a present stimulus






29. Famous for the theory of color blindness






30. 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






31. 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.






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






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

34. Along the visual pathway is the...






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






36. Why do cones see better than rods?






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






38. 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






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






40. Comes from the complexity of the sound wave






41. Best at seeing fine details






42. 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.






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






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






45. 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






46. 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






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






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






49. 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






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