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






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






3. The chemical that aids the receptor cells in transduction






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






5. 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






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






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






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






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






10. humans best hear at






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






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






13. How movement is perceived though the displacement of objects over time - and how this motion takes place at seemingly different paces for nearby or faraway objects. Ships far away seem to move more slowly than ships moving at the same speed.






14. Why do cones see better than rods?






15. 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.






16. Asserts that perception and cognition are largely innate






17. Is the inability to recognize faces






18. Rightly stating that no stimulus exists






19. 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.






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






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






22. 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.






23. The physical intensity of light






24. Proposed the perceptual development and optic array






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






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






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

28. Comes from the complexity of the sound wave






29. 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






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






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






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






33. 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'






34. Found that infants prefer relatively complex and sensational displays






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






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






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






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






39. Famous for the theory of color blindness






40. Is the result of regeneration of retinal pigment






41. Correctly sensing a stimulus






42. 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






43. Proposed the opponent color/process theory






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






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






46. Best at seeing fine details






47. 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.






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






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






50. 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.
