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. 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






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






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






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






5. 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.






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






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






8. 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.






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






10. The physical intensity of light






11. Is the inability to recognize faces






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






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

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






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






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






17. 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'






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






19. We see objects because of the light they reflect






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






21. Has monocular and binocular cues






22. How movement is perceived though the displacement of objects over time - and how this motion takes place at seemingly different paces for nearby or faraway objects. Ships far away seem to move more slowly than ships moving at the same speed.






23. Is the result of regeneration of retinal pigment






24. 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.






25. 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.






26. The feeling that results from physical stimulation






27. 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






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






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

30. Failing to detect a present stimulus






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






32. 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






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






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






36. Asserts that perception and cognition are largely innate






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






38. Comes from the complexity of the sound wave






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






40. 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






41. Saying you detect a stimulus that is not there






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






43. Rightly stating that no stimulus exists






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






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






46. 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






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






48. 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.






49. 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.






50. Is the tendency to complete incomplete figures
