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 composed of photons and waves measured by brightness and wavelengths






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






3. 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






4. The physical intensity of light






5. 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






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






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






8. The feeling that results from physical stimulation






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






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






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






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






13. Proposed the perceptual development and optic array






14. 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.






15. How people perceive objects in the way that they are familiar with them - regardless of changes in the actual retinal image. A book - for example - is perceived as rectangular in shape no matter what angle it is seen from.






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






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






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






19. 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






20. Located by the cornea






21. Is the tendency to complete incomplete figures






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






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






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






25. 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.






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






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






28. 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






29. Or overlap of objects shows which objects are closer






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






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






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






33. Rightly stating that no stimulus exists






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






35. Proposed the opponent color/process theory






36. 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






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






38. 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






39. humans best hear at






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






41. Is the inability to recognize faces






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






43. Along the visual pathway is the...






44. 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






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






46. Famous for the theory of color blindness






47. 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






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






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






50. The tendency to perceive a smooth motion. This explains why motion is perceived when there is none - often by the use of flashing lights or rapidly shown still-fram pictures - such as in the perception of cartoons. This is apparent motion
