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. 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.






2. Is the result of regeneration of retinal pigment






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






4. 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






5. 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.






6. 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






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






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






9. Proposed the opponent color/process theory






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






11. Asserts that perception and cognition are largely innate






12. humans best hear at






13. Defined the Just Noticeable Difference






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






15. We see objects because of the light they reflect






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






17. Or overlap of objects shows which objects are closer






18. 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.






19. 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






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. The physical intensity of a sound wave largely determines loudness






22. 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

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






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

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






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






27. 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






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






29. Rightly stating that no stimulus exists






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






32. Comes from the complexity of the sound wave






33. 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.






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






35. Famous for the theory of color blindness






36. Best at seeing fine details






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






38. Why do cones see better than rods?






39. Has monocular and binocular cues






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






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






42. The chemical that aids the receptor cells in transduction






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






44. 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






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






46. 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.






47. Correctly sensing a stimulus






48. The feeling that results from physical stimulation






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






50. Found that infants prefer relatively complex and sensational displays
