Continuous Partial Attention
Author Steven Berlin Johnson describes one kind of multitasking: “It usually involves skimming the surface of the incoming data, picking out the relevant details, and moving on to the next stream. You’re paying attention, but only partially. That lets you cast a wider net, but it also runs the risk of keeping you from really studying the fish." Multimedia pioneer Linda Stone coined the phrase "continuous partial attention" for this kind of processing. Continuous partial attention is multitasking where things do not get studied in depth.
Rapidly increasing technology fosters multitasking because it promotes multiple sources of input at a given time. Instead of exchanging old equipment like TV, print, and music, for new equipment such as computers, the Internet, and video games children and teens combine forms of media and continually increase sources of input. According to studies by the Kaiser Family Foundation, in 1999 only 16 percent of time spent using media such as internet, television, video games, telephones, text-messaging, or e-mail was combined. In 2005, 26 percent of the time this media was used together. This increase in media usage decreases the amount of attention paid to each device. Today 82 percent of youth use the Internet by the seventh grade, according to the Pew Internet and American Life Project. A 2005 survey by the Kaiser Family Foundation found that, while their usage of media continued at a constant 6.5 hours per day, Americans ages 8 to 18 were crowding roughly 8.5 hours’ worth of media into their days due to multitasking. The survey showed that one quarter to one third of the participants have more than one input “most of the time” while watching television, listening to music, or reading. The 2007 Harvard Business Review featured Linda Stone’s idea of “continuous partial attention,” or, “constantly scanning for opportunities and staying on top of contacts, events, and activities in an effort to miss nothing”. As technology provides more distractions, attention is spread among tasks more thinly.
A prevalent example of this inattention to detail due to multitasking is apparent when people talk on cell phones while driving. Talking and driving are mutually exclusive because focusing on both the conversation and the road uses the same part of the brain. As a result, people generally become more concerned with their phone conversations and do not concentrate on their immediate surroundings. A 2006 study published in the Human Factors journal showed that drivers talking on cell phones were more involved in rear-end collisions and sped up slower than drivers intoxicated over the .08% legal limit. When talking, people must withdraw their attention from the road in order to formulate responses. Because the brain cannot focus on two sources of input at one time, driving and listening or talking, constantly changing input provided by cell phones distracts the brain and increases the likelihood of accidents.

Famous quotes containing the words continuous, partial and/or attention:
“We read poetry because the poets, like ourselves, have been haunted by the inescapable tyranny of time and death; have suffered the pain of loss, and the more wearing, continuous pain of frustration and failure; and have had moods of unlooked-for release and peace. They have known and watched in themselves and others.”
—Elizabeth Drew (1887–1965)
“America is hard to see.
Less partial witnesses than he
In book on book have testified
They could not see it from outside....”
—Robert Frost (1874–1963)
“The mere existence of an additional child or children in the family could signify Less. Less time alone with parents. Less attention for hurts and disappointments. Less approval for accomplishments. . . . No wonder children struggle so fiercely to be first or best. No wonder they mobilize all their energy to have more or most. Or better still, all.”
—Adele Faber (20th century)
