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






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






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






4. 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






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

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






8. Rightly stating that no stimulus exists






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






10. How we organize or experience sensations






11. The feeling that results from physical stimulation






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






13. Defined the Just Noticeable Difference






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






15. 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






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






17. Famous for the theory of color blindness






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






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






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






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






22. Correctly sensing a stimulus






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






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






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






26. 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.






27. 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.






28. 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






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






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






31. 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






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

33. 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

34. 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.






35. 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






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






37. 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.






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






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






40. 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






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






42. 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.






43. Comes from the complexity of the sound wave






44. We see objects because of the light they reflect






45. 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'






46. Proposed the opponent color/process theory






47. Located by the cornea






48. The physical intensity of light






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






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