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. All the things a person sees trains them to perceive






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






3. Famous for the theory of color blindness






4. Proposed the opponent color/process theory






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






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






7. 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.






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. Defined the Just Noticeable Difference






10. 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.






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






12. Factors into why we see what we expect to see






13. Is the result of regeneration of retinal pigment






14. Found that infants prefer relatively complex and sensational displays






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






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






17. 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






18. humans best hear at






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. The physical intensity of light






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






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






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






24. 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.






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

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






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






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






29. Located by the cornea






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






31. The center of the retina; has the greatest visual acuity






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

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






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






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






36. 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






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






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






39. 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






40. 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

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






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






43. Proposed the perceptual development and optic array






44. The chemical that aids the receptor cells in transduction






45. Failing to detect a present stimulus






46. 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






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






48. Correctly sensing a stimulus






49. 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






50. 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.
