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. 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.






2. Found that infants prefer relatively complex and sensational displays






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






4. Failing to detect a present stimulus






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






6. 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'






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






8. 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






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






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






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






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






14. Defined the Just Noticeable Difference






15. Is the result of regeneration of retinal pigment






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






17. Along the visual pathway is the...






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






19. 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






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

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






22. The physical intensity of light






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






24. 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






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






26. 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






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






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






29. 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






30. Or overlap of objects shows which objects are closer






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






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






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






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






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






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






37. The chemical that aids the receptor cells in transduction






38. Asserts that perception and cognition are largely innate






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






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






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






42. We see objects because of the light they reflect






43. 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.






44. 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






45. The feeling that results from physical stimulation






46. Correctly sensing a stimulus






47. Is the tendency to complete incomplete figures






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






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






50. How we organize or experience sensations
