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.

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






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






3. Comes from the complexity of the sound wave






4. Why do cones see better than rods?






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






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






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






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






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






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






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






12. Rightly stating that no stimulus exists






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






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






15. Is the tendency to see what is easiest or logical to see






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






17. 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.






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






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






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






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






22. 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.






23. 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.






24. 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






25. Discovered that cells in the visual cortex were so complex and specialized that they respond to certain types of stimuli. For example - some cells only respond to vertical lines - whereas some respond to only right angles.






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






27. 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






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






29. Proposed the perceptual development and optic array






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






31. 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






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






33. Famous for the theory of color blindness






34. Is the result of regeneration of retinal pigment






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






36. Failing to detect a present stimulus






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






38. 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


39. 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.






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


41. 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






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






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






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






45. 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






46. Found that infants prefer relatively complex and sensational displays






47. 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.






48. Asserts that perception and cognition are largely innate






49. 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.






50. How we organize or experience sensations
