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






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






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






4. 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

5. 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.






6. He tendency to group together items that are near each other






7. Correctly sensing a stimulus






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






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






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

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






12. 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.






13. Best at seeing fine details






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






15. 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.






16. 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






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






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






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






20. 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.






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






22. Has monocular and binocular cues






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






24. Rightly stating that no stimulus exists






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






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






27. 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.






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






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






30. Famous for the theory of color blindness






31. Along the visual pathway is the...






32. 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'






33. Located by the cornea






34. Is the inability to recognize faces






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






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






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

38. 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.






39. 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.






40. Proposed the opponent color/process theory






41. 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






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






43. 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






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






45. 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






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






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






48. The physical intensity of light






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






50. All the things a person sees trains them to perceive
