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 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






3. Rightly stating that no stimulus exists






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






5. 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.






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






7. 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






8. 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.






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






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






11. The physical intensity of light






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






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






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






15. Proposed the perceptual development and optic array






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






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






18. 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.






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






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






21. Asserts that perception and cognition are largely innate






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

23. 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.






24. Is the result of regeneration of retinal pigment






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






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






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






28. 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






29. Is the inability to recognize faces






30. Has been explained as the increasing ability of a child to make finer discriminations among stimuli.






31. humans best hear at






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






33. Along the visual pathway is the...






34. Is the tendency to complete incomplete figures






35. We see objects because of the light they reflect






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






37. Famous for the theory of color blindness






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






39. Proposed the opponent color/process theory






40. 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






41. 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






42. 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'






43. 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.






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






45. 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






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






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






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






49. Electrical impulses travel down these to the brain - where the information is understood






50. 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
