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






2. humans best hear at






3. Found that infants prefer relatively complex and sensational displays






4. Saying you detect a stimulus that is not there






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






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






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






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






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






11. 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

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






13. Asserts that perception and cognition are largely innate






14. Proposed the opponent color/process theory






15. 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.






16. 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






17. The chemical that aids the receptor cells in transduction






18. 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.






19. 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






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






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






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






23. Along the visual pathway is the...






24. Why do cones see better than rods?






25. 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.






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






27. 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






28. 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






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






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






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

32. We see objects because of the light they reflect






33. Best at seeing fine details






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






35. A theory for color vision. It suggests that two types of color sensitive cells exist: Cones that respond to blue-yellow colors and cones that respond to red-green. When one color of the cone is stimulated - the other is inhibited.






36. 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.






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






38. Is composed of photons and waves measured by brightness and wavelengths






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






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






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






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






43. Proposed the perceptual development and optic array






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






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






46. Comes from the complexity of the sound wave






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






48. 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






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






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