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 the inability to recognize faces






2. Best at seeing fine details






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






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

5. 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






6. Famous for the theory of color blindness






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






8. Proposed the opponent color/process theory






9. He tendency to group together items that are near each other






10. Failing to detect a present stimulus






11. Located by the cornea






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






13. 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






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






15. 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.






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






17. Is the result of regeneration of retinal pigment






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






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






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






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






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






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






24. 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.






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






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






27. 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






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






29. The physical intensity of light






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






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






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






33. 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.






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






35. Saying you detect a stimulus that is not there






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






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






38. 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






39. 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.






40. How we organize or experience sensations






41. 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'






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






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






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






45. Why do cones see better than rods?






46. 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.






47. 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.






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

49. Found that infants prefer relatively complex and sensational displays






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