“There are some instances when multitasking can be beneficial, but most of the implications of multitasking are negative,” Dr. Syed says.

It may seem like we’re being more productive by getting several things done at the same time, but it’s more likely that multitasking actually detracts from our efficacy in each individual task, he says.

"For example, if I'm texting during a meeting, I'm probably not paying complete attention to what’s being said in the meeting," he says. "And, I’m probably rushing my text, and the message may come across as uncaring or crude. So neither task will get my full attention.”

Although it may seem that a person can do several things at once, in reality, the brain is able to perform one single task at a time.

“When we multitask, we are actually toggling back and forth between tasks,” Dr. Syed says.

But the result of chronic multitasking may be even more dangerous than incomplete or compromised tasks. It can also impart damage – physically, emotionally and socially.

The stress generated by trying to do too many things at once may actually damage a part of our brains called the anterior cingulate cortex,  Dr. Syed says. This part of the brain is thought to be involved in such diverse functions as regulating blood pressure and heart rate, decision-making, impulse control, reward anticipation, ethics and empathy for others.

“Studies have revealed actual damage to that part of the brain due to stress from multitasking,” Dr. Syed says. “That may help to explain the lack of empathy demonstrated by many young people who are constantly using their cell phones today.”
