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






2. Famous for the theory of color blindness






3. 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






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






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






6. Has monocular and binocular cues






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






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






9. Or overlap of objects shows which objects are closer






10. Proposed the perceptual development and optic array






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






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






13. 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.






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






15. 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






16. Along the visual pathway is the...






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






18. Defined the Just Noticeable Difference






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






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






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






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






23. 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.






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






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






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






27. Is the result of regeneration of retinal pigment






28. Asserts that perception is the sum total of sensory input. The world is understood through bottom-up processing






29. 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






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






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






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






33. 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






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






35. Proposed the opponent color/process theory






36. 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

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






38. 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.






39. The chemical that aids the receptor cells in transduction






40. Correctly sensing a stimulus






41. Asserts that perception and cognition are largely innate






42. 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.






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






44. 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






45. The physical intensity of light






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






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






48. Is the tendency to complete incomplete figures






49. 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'






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