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. Proposed the perceptual development and optic array






2. Saying you detect a stimulus that is not there






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






4. 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.






5. 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.






6. 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.






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






8. Asserts that perception and cognition are largely innate






9. Found that infants prefer relatively complex and sensational displays






10. The chemical that aids the receptor cells in transduction






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

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






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






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






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






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






17. 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






18. Is the result of regeneration of retinal pigment






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






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






21. The feeling that results from physical stimulation






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






24. 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






25. 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






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






27. Suggests that there are three types of receptors in the retina: cones that respond to red - blue - or green






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






29. Failing to detect a present stimulus






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






31. Has monocular and binocular cues






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






33. 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

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






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






36. 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.






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






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






39. 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






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






41. 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.






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






43. Located by the cornea






44. 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






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






46. Or overlap of objects shows which objects are closer






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






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






49. 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.






50. Along the visual pathway is the...
