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. Located by the cornea






2. Asserts that perception and cognition are largely innate






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






4. The chemical that aids the receptor cells in transduction






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






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






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






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






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






10. 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






11. 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.






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






13. 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






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






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






16. Famous for the theory of color blindness






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






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






19. The way that a single point of light viewed in darkness will appear to shake or move. the reason for this is the movement of our own eyes






20. Along the visual pathway is the...






21. 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






22. 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






23. 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

24. humans best hear at






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






26. How we organize or experience sensations






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






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






29. Has monocular and binocular cues






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






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






32. Rightly stating that no stimulus exists






33. 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






34. Is the minimum amount of stimuli that can be detected 50% of the time






35. Is the result of regeneration of retinal pigment






36. 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






37. Correctly sensing a stimulus






38. Is the inability to recognize faces






39. 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






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






41. Why do cones see better than rods?






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






44. 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.






45. We see objects because of the light they reflect






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

47. Failing to detect a present stimulus






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






49. 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






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