We live in a world where multitasking It seems like a necessity. We work on the computer while answering messages, we listen music while we study, we cook while watching TV. But our brain is really capable of Manage multiple tasks at once? Let's find out if multitasking is really as effective as we believe on the basis of scientific evidence.
Multitasking is the perceived ability to perform multiple tasks at the same time. However, experts distinguish between multitasking and "task-switching", i.e. the rapid transition from one task to another. In reality, the human brain struggles to perform two complex tasks in the especially if both require attention and concentration.
When we try to do several things at once, the cortex prefrontal of the brain, responsible for concentration and the process of decision-making, is forced to divide itself between the various tasks. This leads to a general slowdown in performance and a increase of mental fatigue. In addition, this "bottleneck limits our ability to process more information simultaneously, often leading to errors and loss of efficiency.
Several scientific studies have shown that Multitasking reduces productivity and increases the time it takes to complete tasks.
For example, Sandra Bond Chapman, founder of the Center for Brain Health of the University of Dallas, in its research has Demonstrated that an excessive load of material to be processed leads to a surge of the level of cortisol, the stress hormone. This can be explained by reasons biological: neurons are not made to perform many activities simultaneously and are unable to divide the tasks.
The same conclusions were also reached by the researchers from the University of Sussex, who also made an interesting Discovery on the effects of multitasking: a lower density of matter gray in the cerebral area of the anterior cingulate cortex (ACC), involved in thought processing and emotional control. This is reflects in a shorter attention span and a more significant risk of anxiety and depression.
Contrary to popular belief, multitasking therefore it does not make us more productive, but undermines our ability to concentration. When we constantly alternate between different tasks, the our attention is fragmented and it takes us longer to recover the initial focus. In addition, multitasking is associated with increased stress, as the brain is constantly under pressure to handle more information at the same time.
Are there any exceptions? Multitasking can be effective only in certain cases, for example when an activity is automatic and does not require cognitive effort, such as walking and listening to a podcast. At least as long as we are on a known path, otherwise we risk or to cross the road with a red light. Some athletes and musicians they can handle multiple actions at the same time, but this is due to a long and muscle memory.
To increase efficiency and concentration, it is preferable to adopt strategies that reduce multitasking. Some useful techniques include:
Science confirms that multitasking, in most cases, In some cases, it reduces effectiveness and increases mental fatigue. It's better focus on one task at a time to achieve better results and reduce Stress: the key to greater productivity lies in management intelligent of time and attention. And if you need an immediate mental recharge, test The functional drink for concentration and regains focus and attention sip after sip.
