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

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






3. Rods and cones on the retina that are responsible for sensory transduction.






4. Is the result of regeneration of retinal pigment






5. Proposed the opponent color/process theory






6. Has monocular and binocular cues






7. The physical intensity of light






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






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






10. 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






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






12. Asserts that perception and cognition are largely innate






13. 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.






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






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






16. The chemical that aids the receptor cells in transduction






17. 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.






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






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






20. 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.






21. 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

22. 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






23. 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






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. Failing to detect a present stimulus






26. Or overlap of objects shows which objects are closer






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






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






29. Proposed the perceptual development and optic array






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






31. Correctly sensing a stimulus






32. 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






33. 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






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

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






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






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






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






39. 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






40. humans best hear at






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






42. How we organize or experience sensations






43. 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.






44. Rightly stating that no stimulus exists






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






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






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






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






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






50. Comes from the complexity of the sound wave
