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






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






3. 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






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






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






6. 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






7. The chemical that aids the receptor cells in transduction






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






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






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






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. Defined the Just Noticeable Difference






13. 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






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






15. Saying you detect a stimulus that is not there






16. Rightly stating that no stimulus exists






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






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






19. 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






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






21. Is the inability to recognize faces






22. Along the visual pathway is the...






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






24. 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






25. Correctly sensing a stimulus






26. Or overlap of objects shows which objects are closer






27. Is composed of photons and waves measured by brightness and wavelengths






28. 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.






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






30. Proposed the opponent color/process theory






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






32. How we organize or experience sensations






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






34. Best at seeing fine details






35. The physical intensity of light






36. 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






37. 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.






38. 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.






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






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






41. Located by the cornea






42. Has monocular and binocular cues






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

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






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






46. 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

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






48. Is the way that perceived color brightness changes with the level of illumination in the room. With lower levels of illumination - the extremes of the color spectrum (especially red) are seen as less bright






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






50. 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.
