Multi-tasking could reduce performance. But how to turn back the clock?

07 Sep

What would you say about findings that say multi-tasking affects ‘memory creation?’

After all, we email and text while writing reports or watching a movie, don’t we? I just read a 2016 report by Common Sense Media that looked at recent literature of Technology Addiction. here are some alarming findings. Some are red flags, needing more research.

Here are just a few:

  • Media Multi-tasking creates cognitive fatigue, and makes it more difficult for someone to create memories that can be accurately retrieved.
  • Heavy multi-taskers have a harder time filtering out irrelevant information (2009 study of college students)
  • Students who multi-tasked using a laptop during a lecture performed worse on a test, compared to students who were not using a laptop. (2013 study of college students)
  • US ‘Tweens’ (8- to 12-year-olds) spend 5:55 hours outside of school and homework using media. Teens spend 8:56 hours (2015 survey)

The reference to media in media multi-tasking, refers to both digital and non-digital media: TV, video games,social media, using the Internet, reading, and listening to music.

What do we do about these findings? Many parents do not need research to tell them that they (and their kids) must cut back. I have met parents who have taken steps such as not have more than one device in the home, and those who have a ‘digital curfew’ after, say 8:00 pm. There are even those who do not allow mobile devices and tablets in children’s bedrooms – similar to the earlier trend of not having a TV in bedroom.

I teach computers and technology, making it a curious place to discuss this. I often require students to use paper and pencil, even though they come to my Lab to learn about such things as audio recordings (on a cloud-based digital console), QR codes, and search strategies. I often get asked if listening to music while working is OK (they know the answer but think it’s worth a shot!).

Could we turn back the clock, and get back to mono-tasking?
