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. Why do cones see better than rods?






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






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






4. Found that infants prefer relatively complex and sensational displays






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






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






7. Proposed the perceptual development and optic array






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






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






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






11. Best at seeing fine details






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






13. 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






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






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






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






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






18. Proposed the opponent color/process theory






19. How we organize or experience sensations






20. The chemical that aids the receptor cells in transduction






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






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






23. Asserts that perception and cognition are largely innate






24. The feeling that results from physical stimulation






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






26. 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






27. Failing to detect a present stimulus






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

29. We see objects because of the light they reflect






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






31. 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

32. Has monocular and binocular cues






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






34. 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.






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






36. Revolves around perception and asserts that people tend to see the world as comprised of organized wholes. The world is understood through top-down processing.






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






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






39. 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.






40. humans best hear at






41. Defined the Just Noticeable Difference






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






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






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






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






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






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






48. 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






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






50. 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
