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. 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






2. Also known as color - is the dominant wavelength of light






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






4. 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.






5. 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






6. Is the inability to recognize faces






7. 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






8. Is the result of regeneration of retinal pigment






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






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






11. Has monocular and binocular cues






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






13. Correctly sensing a stimulus






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






15. 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






16. We see objects because of the light they reflect






17. How we organize or experience sensations






18. 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

19. Located by the cornea






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






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






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

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






24. humans best hear at






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






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






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






28. Why do cones see better than rods?






29. Is the tendency to make figures out of symmetrical images






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






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






32. Allow the cornea to bend (accommodate) in order to focus an image of the outside world onto the retina






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






34. The chemical that aids the receptor cells in transduction






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. Rightly stating that no stimulus exists






37. Along the visual pathway is the...






38. All the things a person sees trains them to perceive






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






40. Or overlap of objects shows which objects are closer






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






42. 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.






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






44. 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.






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






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






47. 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






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






49. Electrical impulses travel down these to the brain - where the information is understood






50. 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
