  • 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 part of the world that triggers a particular neuron






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






3. All the things a person sees trains them to perceive






4. Found that infants prefer relatively complex and sensational displays






5. 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






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

7. Located by the cornea






8. Famous for the theory of color blindness






9. 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.






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






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






12. Proposed the opponent color/process theory






13. 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






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






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






16. 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.






17. Why do cones see better than rods?






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






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






20. 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






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






22. Is the tendency to complete incomplete figures






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






24. Where half of all fibers from the optic nerve of each eye cross over and join the optic nerve from the other eye. This insures input from each eye will be put together in a full picture in the brain.






25. 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






26. Best at seeing fine details






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






28. The physical intensity of light






29. Defined the Just Noticeable Difference






30. 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






31. Has monocular and binocular cues






32. Proposed the perceptual development and optic array






33. Knowing that an elephant is large no matter how it might appear






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






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






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






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






38. The chemical that aids the receptor cells in transduction






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






40. 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

41. 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






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






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






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






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






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






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






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






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






50. We see objects because of the light they reflect
