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.

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






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






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






4. 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.






5. Found that infants prefer relatively complex and sensational displays






6. 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

7. Proposed the perceptual development and optic array






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






9. 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






10. After the optic chasm - information travels to the...






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






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






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






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






15. 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.






16. 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'






17. Best at seeing fine details






18. Proposed the opponent color/process theory






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






20. 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.






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






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






23. 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.






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

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






26. Along the visual pathway is the...






27. 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






28. 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






29. Has monocular and binocular cues






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






31. 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






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






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






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






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






36. 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






37. Correctly sensing a stimulus






38. Saying you detect a stimulus that is not there






39. Is the tendency to complete incomplete figures






40. 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






41. Is the result of regeneration of retinal pigment






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






43. Is the inability to recognize faces






44. Famous for the theory of color blindness






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






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






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






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






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






50. 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.
