Document Summary
Divided attention: paying attention to a number of things at once. Selective attention: focusing on specific objects and ignoring others. We look at things that are interesting. Problem the visual system faces is that there is so much information being sent from the retina to the brain that if the visual system had to deal with all of it, it would overload. To deal with this problem, the visual system is designed to select only a small part of this information to process and analyze. We can pay attention to things that are not directly on our line of vision. We can look directly at something without paying attention to it. There is a mental aspect of attention that occurs in addition to eye movement. James: we focus on some things to the exclusion of others. Fixations: places where the eye pauses to take in information about specific parts of the scene.
