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






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






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






4. 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.






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






6. Comes from the complexity of the sound wave






7. 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






8. Is the inability to recognize faces






9. 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






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






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






12. 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.






13. 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






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






15. 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






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






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






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






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






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






21. The chemical that aids the receptor cells in transduction






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






23. Asserts that perception and cognition are largely innate






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






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






26. Rightly stating that no stimulus exists






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

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






29. 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






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






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






32. 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

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






34. 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.






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






36. Allow the cornea to bend (accommodate) in order to focus an image of the outside world onto the retina






37. 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.






38. 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.






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

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






41. Or overlap of objects shows which objects are closer






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






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






44. Best at seeing fine details






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






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






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






48. Has monocular and binocular cues






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






50. 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
