Many people these days – youngsters in particular – believe in their ability to perform more than one task at the same time, or to ‘multitask’. In this post we listen to what the research has to say about ‘media multitasking’. Before you listen, discuss the following questions with a friend:

  • Are you good at multitasking?
  • Do you multitask when using electronic devices? Which ones?
  • Can multitasking make you smarter?

Facts about media multitasking

  • Many US adults use another device while watching TV.
  • Contrary to popular belief, multitasking does not improve memory and attention.

What is media multitasking?

  • Using more than one device at the same time, for example using your smartphone when watching TV.
  • Playing a video game and at the same time sending texts to friends or listening to music.

What do researchers say about media multitasking?

  • Heavy media multitaskers have poorer sustained attention than light media multitaskers.
  • In working memory tests, heavy media multitaskers are also weaker than light media multitaskers.
  • Heavy media multitaskers and light media multitaskers have differently structured brains.
  • Researchers remain uncertain about the causes of heavy media multitasking.

A benefit of heavy media multitasking

Light media multitaskers may not notice helpful information unrelated to their main task. Heavy media multitaskers are more likely to notice a breaking news forecast, for example.

Should we avoid it?

Yes and no.

  • Yes. When you do two things at the same time the brain experiences an attentional bottleneck and only allows tasks to be performed one after the other.
  • No. More research is needed before we start panicking about media multitasking and its potentially negative effects.

Media Multitasking

How many times have you sat down to watch TV or a movie, only to immediately shift your attention to your smartphone or tablet? Known as “media multitasking”, this phenomenon is so common that an estimated 178m US adults regularly use another device while watching TV. While some might assume that frequently shifting your attention between different information streams is good brain training for improving memory and attention, studies have found the opposite to be true.

Media multitasking is when people engage with multiple devices or content at the same time. This might be using your smartphone while watching TV, or even listening to music and text messaging friends while playing a video game.

One recent study looked at the body of current research on media multitasking (consisting of 22 peer-reviewed research papers) and found that self-reported “heavy media multitaskers” performed worse on attention and working memory tests. Some even had structural brain differences.

The study found that “heavy” media multitaskers performed about 8-10% worse on sustained attention tests compared to “light” media multitaskers. These tests involved participants paying attention to a certain task (such as spotting a specific letter in a stream of other letters) for 20 minutes or more.

Researchers found that on these tests (and others) the ability to sustain attention was poorer for heavy multitaskers. These findings might explain why some people are heavy multitaskers. If someone has a poor attention span, they may be likely to switch between activities quickly, instead of staying with just one.

Heavy media multitaskers were also found to perform worse than light media multitaskers on working memory tests. These involved memorising and remembering information (like a phone number) while performing another task (such as searching for a pen and piece of paper to write it down). Complex working memory is closely linked with having better focus and being able to ignore distractions.

Brain scans of the participants also showed that an area of the brain known as the anterior cingulate cortex is smaller in heavy multitaskers. This area of the brain is involved in controlling attention. A smaller one may imply worse functioning and poorer attention.

But while researchers have confirmed that heavy media multitaskers have worse memory and attention, they are still uncertain about what causes heavy media multitasking. Do heavy media multitaskers have worse attention because of their media multitasking? Or do they media multitask because they have poor attention? It might also be an effect of general intelligence, personality, or something else entirely that causes poor attention and increased media multitasking behaviours.

But the news isn’t all bad for heavy multitaskers. Curiously, this impairment might have some benefit. Research suggests that light media multitaskers are more likely to miss helpful information that isn’t related to the task they’re currently performing. For example, a person may read with a radio playing in the background. When important breaking news is broadcast, a heavy media multitasker is actually more likely to pick it up than a light media multitasker.

So should you avoid media multitasking? Based on current research, the answer is probably yes. Multitasking usually causes poorer performance when doing two things at once, and puts more demands on the brain than doing one thing at a time. This is because the human mind suffers from an “attentional bottleneck”, which only allows certain mental operations to occur one after another.

But if you’re wondering whether media multitasking will impair your attention capabilities, the answer is probably no. We don’t know yet whether heavy media multitasking is really the cause for lower performance on the tests. The effects observed in controlled laboratory settings are also generally rather small and most likely negligible in normal everyday life. Until we have more research, it’s probably too early to start panicking about the potential negative effects of media multitasking.
