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. Best at seeing fine details






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






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






4. Correctly sensing a stimulus






5. 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'






6. The most famous of all visual illusions. Two horizontal lines of equal length appear unequal because of the orientation of the arrow marks at the end. Inward facing arrow marks make the line appear shorter than another line of the same length with ou






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






8. Defined the Just Noticeable Difference






9. Asserts that perception is the sum total of sensory input. The world is understood through bottom-up processing






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






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






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






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






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






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






16. 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






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






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






19. 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.






20. 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.






21. Is the tendency to complete incomplete figures






22. 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.






23. Saying you detect a stimulus that is not there






24. Located by the cornea






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






26. How we organize or experience sensations






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






28. 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






29. 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






30. We see objects because of the light they reflect






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






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






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






34. 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






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






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






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






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






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






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






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






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






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






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






45. Rightly stating that no stimulus exists






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






47. Proposed the perceptual development and optic array






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






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






50. 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.
