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






2. Asserts that perception and cognition are largely innate






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






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






5. 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'






6. 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






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






8. 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.






9. humans best hear at






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

11. 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.






12. 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






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






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






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






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






17. 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.






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






19. 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






20. 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.






21. Rightly stating that no stimulus exists






22. 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.






23. Located by the cornea






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






25. 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






26. Correctly sensing a stimulus






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






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. Is the result of regeneration of retinal pigment






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






31. 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

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






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






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






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






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






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






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






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






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






43. 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






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






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






46. Proposed the opponent color/process theory






47. Found that infants prefer relatively complex and sensational displays






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