new research by EyalOphir, Clifford Nass, and Anthony D. Wagner at Stanford University suggests that people who multitask suffer from a problem: weaker self-control ability.

then recruited people who had scores that were extremely high or low and asked them perform a series of tests designed to measure the ability to control one's attention, one's responses, and the contents of one's memory. They found that the high- and low- media-multitasking groups were equally able to control their responses, but that the heavy media-multitasking group had difficulties, compared to the low media-multitasking group, when asked to ignore information that was in the environment or in their recent memory. They also had greater trouble relative to their counterparts when asked to switch rapidly between two different tasks. This last finding was surprising, because psychologists know that multitasking involves switching rapidly between tasks rather than actually performing multiple tasks simultaneously.

It seems that chronic media-multitaskers are more susceptible to distractions. In contrast, people who do not usually engage in media-multitasking showed a greater ability to focus on important information. According to the researchers, this reflects two fundamentally different strategies of information processing. Those who engage in media-multitasking more frequently are "breadth-biased," preferring to explore any available information rather than restrict themselves. AsLin Lin at the University of North Texas puts it in a review of the article, they develop a habit of treating all information equally. On the other extreme are those who avoid breadth in favor of information that is relevant to an immediate goal.
