  • 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.

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






3. humans best hear at






4. 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






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






6. We see objects because of the light they reflect






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






8. 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






9. 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.






10. 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.






11. Proposed the perceptual development and optic array






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






13. Failing to detect a present stimulus






14. Located by the cornea






15. 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






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






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






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






19. 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.






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






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






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






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






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






25. Along the visual pathway is the...






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






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






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

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






31. Rightly stating that no stimulus exists






32. Has monocular and binocular cues






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






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






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






36. Asserts that perception and cognition are largely innate






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






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

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






40. 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.






41. Or overlap of objects shows which objects are closer






42. Correctly sensing a stimulus






43. Famous for the theory of color blindness






44. 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






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






46. 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






47. How we organize or experience sensations






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






49. Defined the Just Noticeable Difference






50. 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
