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. 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.






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






3. Or overlap of objects shows which objects are closer






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






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






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






7. The physical intensity of light






8. 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.






9. Located by the cornea






10. Along the visual pathway is the...






11. Why do cones see better than rods?






12. 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






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






14. Best at seeing fine details






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






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






17. Rightly stating that no stimulus exists






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






19. Has monocular and binocular cues






20. 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






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






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






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






24. 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

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






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






27. Is the result of regeneration of retinal pigment






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






30. How we organize or experience sensations






31. The chemical that aids the receptor cells in transduction






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






33. Proposed the perceptual development and optic array






34. 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






35. 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






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






37. We see objects because of the light they reflect






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






39. 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






40. 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






41. Comes from the complexity of the sound wave






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






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






44. 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.






45. Is the tendency to create a whole or detailed figure based on our expectations rather than what is seen






46. 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






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






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






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






50. Is the tendency to complete incomplete figures
