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






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






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






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






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






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






7. The feeling that results from physical stimulation






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






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






10. Located by the cornea






11. 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.






12. 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






13. We see objects because of the light they reflect






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






15. 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






16. Along the visual pathway is the...






17. 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






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






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. Is when two horizontal lines of equal length appear unequal because of two vertical lines that slant inward






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






22. 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






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






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






25. 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.






26. 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






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






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






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






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






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






32. 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






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






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






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


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






37. 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'






38. Defined the Just Noticeable Difference






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






40. humans best hear at






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






42. 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






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






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






45. Rightly stating that no stimulus exists






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


47. Allows the eyes to see contrast and prevents repetitive information from being sent to the brain. Once the receptor cell is stimulated - the others nearby are inhibited.






48. Is the tendency to complete incomplete figures






49. 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






50. Found that infants prefer relatively complex and sensational displays
