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. 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






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






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






4. Is the inability to recognize faces






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






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






7. 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.






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






9. humans best hear at






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






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






12. Defined the Just Noticeable Difference






13. Suggests that there are three types of receptors in the retina: cones that respond to red - blue - or green






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






15. Is the result of regeneration of retinal pigment






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

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






18. 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.






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






20. 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






21. 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






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






23. Proposed the tri-color theory - research shows that the opponent-process theory seems to be at work in the Lateral geniculate body - research shows that the tri-color theory seems to be at work in the Retina






24. We see objects because of the light they reflect






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






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






27. 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.






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






29. 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.






30. 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

31. 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.






32. Rightly stating that no stimulus exists






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






34. 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'






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






36. Along the visual pathway is the...






37. Famous for the theory of color blindness






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






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






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






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






42. Located by the cornea






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






44. Has monocular and binocular cues






45. 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.






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






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






48. 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






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






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