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. 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






2. Asserts that perception and cognition are largely innate






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






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






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






6. 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






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


8. Found that infants prefer relatively complex and sensational displays






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






10. 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






11. 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






12. 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.






13. Why do cones see better than rods?






14. Is the result of regeneration of retinal pigment






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






16. 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.






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






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






19. Defined the Just Noticeable Difference






20. Is the inability to recognize faces






21. 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.






22. Has monocular and binocular cues






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






24. 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






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


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






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






28. 1. closure 2. Proximity 3. Continuation or good continuation 4. Symmetry 5. Constancy 6. Minimum principle






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






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






31. The feeling that results from physical stimulation






32. Is the tendency to complete incomplete figures






33. 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






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






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






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






37. 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






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






39. The physical intensity of light






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






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






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






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






44. How we organize or experience sensations






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






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






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






48. 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.






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






50. 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.
