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






2. 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






3. 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.






4. Has been explained as the increasing ability of a child to make finer discriminations among stimuli.






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

6. Famous for the theory of color blindness






7. Rightly stating that no stimulus exists






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






9. 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.






10. 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.






11. 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.






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






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






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






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






16. Is the inability to recognize faces






17. Failing to detect a present stimulus






18. 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'






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






20. Proposed the opponent color/process theory






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






22. Defined the Just Noticeable Difference






23. Found that infants prefer relatively complex and sensational displays






24. 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






25. 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.






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






27. Saying you detect a stimulus that is not there






28. Has monocular and binocular cues






29. 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






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






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






32. Comes from the complexity of the sound wave






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






34. Where half of all fibers from the optic nerve of each eye cross over and join the optic nerve from the other eye. This insures input from each eye will be put together in a full picture in the brain.






35. Is the tendency to complete incomplete figures






36. Along the visual pathway is the...






37. 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






38. Is the result of regeneration of retinal pigment






39. 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






40. 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






41. Proposed the perceptual development and optic array






42. 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






43. The feeling that results from physical stimulation






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






45. 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.






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






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






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






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






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