In the 1990s and 2000s, multitasking was the productivity buzzword.
Multitasking is different to completing individual actions in rapid succession. That is entirely possible, and efficient people can achieve a great deal by lining up the activities and going through them very quickly.
The other alternative is to task switch rapidly while still handling one task at a time.
Neuroscience indicates we are not wired for multitasking
When our brain is required to switch between complex tasks, it can lead to errors and a drop in efficiency, as cited in a study published in the Journal of Experimental Psychology, Human Perception and Performance. Employees who multitask, while appearing to look more productive, were shown to be slower in completing their tasks.
Multitasking linked to cognitive decline
Accident statistics show that a person using a cell phone while driving is more likely to have an accident than one who is not. A study on crash risk factors showed that distraction – like using a cell phone while driving was 3.6 times more likely to result in an accident than under model driving conditions. And students who use cell phones in class tend to have lower results than those who do not.
A University of Sussex study found that the grey matter in our brain’s anterior cingulate cortex (ACC) shrinks when we use multiple technology devices simultaneously – for example, watching TV and texting. The interesting part is that the ACC is related to processing emotions, and juggling multiple tasks simultaneously can result in higher cortisol levels, the stress hormone. Higher cortisol levels for sustained periods are linked to memory decline, with forgetfulness and cognitive decline accelerated over time.
Serial-tasking versus single-tasking
The alternative way of working and living is to concentrate on single tasks resulting in more productivity. If the job is a very long and involved one that could lead to boredom, then it is suggested that setting up time-frames during the day to work on tasks can help so when you get exhausted by one job, you can take on a different quick task and feel good when you complete it. This is known as serial-tasking. With this mindset of accomplishment, you will return to tackling the complex task with renewed energy. It is best to set the more complicated tasks for the morning when you are freshest. On the other hand, single-tasking requires a person to complete tasks assigned in a linear fashion.
People with short attention spans may benefit from serial-tasking. Ultimately, it comes down to what suits you for optimal performance. Experienced multitaskers may not feel it necessary to switch, but if multitasking isn’t for you, then the alternatives of serial or single-tasking are effective options that will keep your grey matter more or less intact.
