You’ve likely heard that multitasking is problematic, but new studies show that it kills your performance and may even damage your brain.
The researchers have found that individuals that are constantly bombarded by several streams of electronic information can not pay attention to, remember information, or move from one job to another, as well as those who perform one task at a time.
1. Special Skill
Multitasking reduces your efficiency and performance because your brain can only focus on one thing at a time. When you try to do two things at once, your brain lacks the capacity to perform both tasks successfully.
The regular multitaskers did worse as they had more difficulty coordinating their thoughts. And also, filtering out irrelevant information and jumping from one task to another was more sluggish.
2. Multitasking Lowers IQ
Research also shows that, in addition to slowing you down, multitasking lowers your IQ.
A study at the University of London found that participants who multitasked during cognitive tasks experienced IQ score declines that were similar to what they’d expect if they had smoked marijuana or stayed up all night.
IQ drops of 15 points for multitasking men lowered their scores to the average range of an 8-year-old child.
3. Brain Damage from Multitasking
While further work is required to determine if it affects the brain directly (as opposed to actual brain damage that predisposes people to multitask), it is clear that it has negative effects.
It is necessary to raise awareness that to communicate with technology can change the way you think. And then, that these changes can occur at the brain structure level.
4. Learning from Multitasking
When multitasking significantly affects the anterior cingulate cortex (the main brain area for EQ), as current research indicates, then the EQ will be lowered in the process.
And any time you’re multitasking you’re not just harming your efficiency at the moment; you could very well damage a part of your brain that’s vital to your potential job success.
