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. Is the tendency to complete incomplete figures






2. Comes from the complexity of the sound wave






3. 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






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






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






6. 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.






7. Rightly stating that no stimulus exists






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

9. 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






10. The chemical that aids the receptor cells in transduction






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






12. Begins with the tympanic membrane (eardrum) which is stretch across the auditory canal. Behind this membrane are the Ossicles (3 small bones) - the last of which is the stapes. Sound vibrations bump against the tympanic membrane - causing the ossicl






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. 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






15. Located by the cornea






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






17. Why do cones see better than rods?






18. How we organize or experience sensations






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






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






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






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






23. 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'






24. Is the inability to recognize faces






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






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






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






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






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






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






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






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






33. The physical intensity of light






34. Along the visual pathway is the...






35. 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.






36. Asserts that perception and cognition are largely innate






37. 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.






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

39. The feeling that results from physical stimulation






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






41. Correctly sensing a stimulus






42. The overarching Gestalt idea that experience will be organized as meaningful - symmetrical - and simple whenever possible.






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






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






45. 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.






46. humans best hear at






47. 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






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






49. Or overlap of objects shows which objects are closer






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