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






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






3. The feeling that results from physical stimulation






4. 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






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






6. humans best hear at






7. Along the visual pathway is the...






8. How we organize or experience sensations






9. 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






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






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






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






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






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






15. 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






16. Correctly sensing a stimulus






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

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






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






20. Why do cones see better than rods?






21. 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.






22. Located by the cornea






23. 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






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






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






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






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






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






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






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






31. 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.






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






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






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. Or overlap of objects shows which objects are closer






36. 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.






37. Comes from the complexity of the sound wave






38. 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






39. 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






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






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






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






43. 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'






44. Is the inability to recognize faces






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






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






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






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






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






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