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. All the things a person sees trains them to perceive






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






4. 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






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






6. The physical intensity of light






7. Correctly sensing a stimulus






8. 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






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






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






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






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






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






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






15. Is the result of regeneration of retinal pigment






16. 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'






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






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






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






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






21. 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






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






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






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






25. We see objects because of the light they reflect






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






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






28. Located by the cornea






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






30. 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






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






32. The chemical that aids the receptor cells in transduction






33. Consists of one optic nerve connection each eye to the brain.






34. Has monocular and binocular cues






35. How we organize or experience sensations






36. 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






37. Failing to detect a present stimulus






38. Along the visual pathway is the...






39. 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






40. humans best hear at






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






42. Or overlap of objects shows which objects are closer






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. Asserts that perception and cognition are largely innate






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






46. 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.






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






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






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






50. Is the inability to recognize faces
