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. 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






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






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






4. 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.






5. Has monocular and binocular cues






6. Is the tendency to complete incomplete figures






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






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






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






10. Comes from the complexity of the sound wave






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






12. The physical intensity of light






13. 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'






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






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






16. Famous for the theory of color blindness






17. Why do cones see better than rods?






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






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






20. 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






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






22. Proposed the perceptual development and optic array






23. 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






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






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


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






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






29. Found that infants prefer relatively complex and sensational displays






30. 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.






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. Asserts that perception and cognition are largely innate






33. Proposed the opponent color/process theory






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






35. 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.






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






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






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






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






40. 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.






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






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






43. The feeling that results from physical stimulation






44. How we organize or experience sensations






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






46. 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.






47. 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






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






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






50. He tendency to group together items that are near each other
