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






2. Defined the Just Noticeable Difference






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. How we organize or experience sensations






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






6. 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.






7. Located by the cornea






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






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






10. 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'






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






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






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






14. We see objects because of the light they reflect






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






16. 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






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






18. Rightly stating that no stimulus exists






19. Asserts that perception and cognition are largely innate






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






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






22. 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






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






24. 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.






25. Correctly sensing a stimulus






26. humans best hear at






27. The feeling that results from physical stimulation






28. 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.






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






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






31. Is the tendency to complete incomplete figures






32. The physical intensity of a sound wave largely determines loudness






33. 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






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






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






36. Is the upper limit above which the stimuli can no longer be perceived. -The highest pitch sound a human could hear






37. 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






38. 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






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. Why do cones see better than rods?






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

Warning: Invalid argument supplied for foreach() in /var/www/html/basicversity.com/show_quiz.php on line 183


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






43. 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






44. Comes from the complexity of the sound wave






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






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






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






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






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






50. Found that infants prefer relatively complex and sensational displays
