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. Or overlap of objects shows which objects are closer






2. How we organize or experience sensations






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






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






5. Along the visual pathway is the...






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

7. Correctly sensing a stimulus






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






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






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






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






12. Famous for the theory of color blindness






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






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






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






16. Is the inability to recognize faces






17. Proposed the opponent color/process theory






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






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






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






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






22. 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'






23. 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






24. 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






25. The physical intensity of light






26. The optic nerve is made up of...






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






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






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






30. 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.






31. 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.






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






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

34. Proposed the perceptual development and optic array






35. Comes from the complexity of the sound wave






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






37. Found that infants prefer relatively complex and sensational displays






38. 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






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






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






41. 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






42. 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






43. Has monocular and binocular cues






44. 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.






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






46. 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.






47. 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






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






49. 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.






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