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






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






3. How we organize or experience sensations






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






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






6. 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






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






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






9. The chemical that aids the receptor cells in transduction






10. 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






11. 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






12. We see objects because of the light they reflect






13. humans best hear at






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






15. Why do cones see better than rods?






16. The feeling that results from physical stimulation






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






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






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






20. Asserts that perception and cognition are largely innate






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






22. 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






23. The physical intensity of light






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






25. 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.






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






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






28. Famous for the theory of color blindness






29. Saying you detect a stimulus that is not there






30. 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.






31. Correctly sensing a stimulus






32. Is the tendency to complete incomplete figures






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






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






35. Found that infants prefer relatively complex and sensational displays






36. Proposed the perceptual development and optic array






37. 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






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






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






40. 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.






41. Is the result of regeneration of retinal pigment






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






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






44. Defined the Just Noticeable Difference






45. Rightly stating that no stimulus exists






46. Are particularly sensitive to dim light and are used for night vision. They are also concentrated along the sides of the retina - making them extremely important for peripheral vision






47. 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.






48. Located by the cornea






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






50. 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'
