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






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






3. 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.






4. The chemical that aids the receptor cells in transduction






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






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






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






8. Is the tendency to complete incomplete figures






9. Famous for the theory of color blindness






10. Proposed the perceptual development and optic array






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






12. 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'






13. 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






14. 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






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






16. 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






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






18. We see objects because of the light they reflect






19. 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

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






22. 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






23. Is gained by features we are familiar with - such as two seemingly parallel lines that converge with distance






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






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






26. Defined the Just Noticeable Difference






27. Proposed the opponent color/process theory






28. 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.






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






30. 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






31. 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






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






33. humans best hear at






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






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. Found that infants prefer relatively complex and sensational displays






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






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






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






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






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






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






43. Located by the cornea






44. Has monocular and binocular cues






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






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






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






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






49. 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.






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