Training does not improve the ability to multitask . In 2009 Eyal Ophir, then at Stanford University, and his colleagues discovered that multitasking on the Internet paradoxically makes users less effective at switching from one task to another. They are less able to allocate their attention and are too vulnerable to distractions. Consequently, even members of the “digital native” generation are unlikely to develop the cognitive control needed to divide their time between several tasks or to instantly switch from one activity to another. In other words, digital multitasking does little more than produce a dangerous illusion of competence .
