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. 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

2. 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






3. 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.






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






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






6. 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






7. 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






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. 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.






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






11. 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'






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






13. 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.






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






15. 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






16. Rightly stating that no stimulus exists






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






18. Defined the Just Noticeable Difference






19. Is the inability to recognize faces






20. We see objects because of the light they reflect






21. 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






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






23. The chemical that aids the receptor cells in transduction






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






25. The clear protective coating on the outside of the eye






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






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






28. Asserts that perception and cognition are largely innate






29. 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.






30. 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






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






32. 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.






33. Found that infants prefer relatively complex and sensational displays






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






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






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






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






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






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






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






41. Famous for the theory of color blindness






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






43. Comes from the complexity of the sound wave






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






45. Correctly sensing a stimulus






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






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






48. How we organize or experience sensations






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






50. Is the tendency to complete incomplete figures
