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






2. 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






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






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






5. 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






6. 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.






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






8. 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.






9. Is the inability to recognize faces






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






11. Gives us clues about how far away an object is if we know about how big the object should be






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






13. 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






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






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






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






17. Found that infants prefer relatively complex and sensational displays






18. 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






19. 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.






20. Correctly sensing a stimulus






21. 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.






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






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






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






25. 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'






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






27. 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






28. Is the result of regeneration of retinal pigment






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






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






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






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






33. 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






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






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






36. Along the visual pathway is the...






37. Located by the cornea






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






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






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






41. Is the tendency to complete incomplete figures






42. Why do cones see better than rods?






43. We see objects because of the light they reflect






44. Comes from the complexity of the sound wave






45. 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.






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






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






48. 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.






49. 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






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