For most people, performing two relatively complex mental tasks at once is practically impossible, unless one of them has been completely automated through practice. “Hold on a second”, I can hear you thinking, “I multitask on a daily basis.” You might think you are, but you are actually task switching, that is alternating between tasks over short periods of time. Unlike multitasking, task switching causes a loss in efficiency.
Different tasks have different objectives and rules, which means that every time you move from one task to another, you must take different objectives and rules into consideration. As tasks become more complex, so do the goals and mental processes associated with them, which leads to a greater loss in efficiency and time. In the end, it takes longer to “multitask” a set of tasks than to complete them one after the other, and the quality of the work may suffer as well.
There are two main reasons why we multitask:
First, the inevitable loss in efficiency means they will need more time to complete their tasks. If their time is limited, either some tasks will remain unfinished or the end results will be of poorer quality. It’s important to note that even with more time on their hands, they may face other negative consequences of multitasking, such as sleep loss.
If they do have enough time, multitasking might work and even be beneficial to learning, as long as they plan their task switching carefully.
Finally, avoid multitasking if the tasks are particularly challenging or if their quality is important. Focusing on every complex task individually is the most efficient and effective way to complete them.
