Скачать или смотреть Multitasking Is a Myth: Task Switching Is Slowing You Down

Your brain can't "multitask"; it just switches between tasks very quickly. The illusion of multitasking is powered by a process called 'task switching,' where our brain's attention flits between different activities. This process isn't free; it imposes a 'switch cost,' a measurable decline in performance and accuracy each time we change focus. Functional magnetic resonance imaging (fMRI) studies show this activity is managed by the frontoparietal control network, the part of the brain responsible for setting goals and filtering information. Because this network isn't optimized for rapid changes, multitasking can lead to decreased productivity, a shorter attention span, and increased stress. By understanding this cognitive limitation, we can see that monotasking—focusing deeply on a single objective—is far more effective for complex work. (Source: news.wfu.edu, news-medical.net)
