The impact of Technology on Attention

Before we get too far, you should probably start by reading my disclaimer. One of my most loved and most hated posts is TV and Computer Time for Babies. Now children not only have screen time from tv and computer, but also from phones and tablets. So, what does the newest research say about all of this screen time?

There seems to be a common belief that kids these days are wired for using technology. It's not a belief based in anything other than convenience. It is easier to set the kids in front of a screen and know they are learning, playing, and happy. This does take a toll that everyone should be aware of.

You may not realize that technology creates more work. Before light handheld irons were common, people would only iron their clothes once a month and the level of acceptable wrinkles was much different. Better technology means we are now ironing more and our standards for wrinkles is much lower. Another example, when I was in elementary through high school and needed to do a research project, I headed to the library. I started at the card catalog - a large box with actual cards representing each book. Teachers would expect 3-5 references. Now everything is digitized and easy to access. Teachers expect more references, higher quality references (not just wikipedia), and more analysis of conflicting research. There are many other examples, but when you really think about it historically, technology has created more work than it has saved.

Kids are being raised on multiple media streams and multi-tasking. 40% of 3 month olds watch 90 minutes of television a day. That goes up to 50% of 8 month olds and 90 percent of 2 year olds. 50% of 8 year olds have their own cell phone. The most commonly requested add on in family cars is a dual screen video player. With all of this early exposure and practice multitasking, how can I say that kids aren't wired for using technology?

It is true that a 22 year old is better at multitasking than a 40 year old. I observe this on an almost daily basis. However, it's not because 22 year olds have more practice, it's because they are 22. Their brains are younger and work faster. Once they are 40, they will be frustrated that they can't multitask as well as most 22 year olds. The more you multitask, the more your long term attention decreases. Distractions start bothering multitaskers much earlier than those who have learned to focus on one thing at a time. Yes, learning to focus on one thing at a time is now something that we should try learning.

Kids spend the first few years of their life playing digital games. Every time they get an answer right there are lights, music, and characters literally dancing in celebration. Then they are placed in school. The human teacher stands at the front. When a student gets the answer correct they may smile and say "that's right" as they continue the lesson. Of course kids see this as being boring. Where's the instant party? Humans are not viewed by the brain as being interesting comparatively. Students get antsy, impulsive, and certainly don't want to do a worksheet.

Stop and think about the goal of education for YOUR child. Is the goal for your child to be entertained? Is the goal for your child to be challenged? Is the goal for your child to learn enough to be successful outside of school? Learning to sit and listen to a human speak and being able to apply what you have just heard is a skill that will be used throughout life. We need to make sure our children are prepared for life, not just playing games on the computer.

Screens do cause attention problems. This has been proven. However the ability to sustain attention is not correlated across tasks, i.e. sustained attention with toys versus videos versus interactive experiments. Video game players do perform better on quick perception tests. The brain is changeable within reason. If you think the computer is saving your work, you don't remember what you just wrote. If you know it's not saving, you will remember what you are typing almost word for word. Multitasking always carries a cost. Having a tv on in the background when you are working is always bad, no matter what task you are completing. (I do feel like a bit of a hypocrite since the tv is on in the background as I write this...) Multitasking causes people to make more mistakes and takes longer for the same task, no matter how much practice you have had or if you are 22. As far as having music in the background, the studies contradict themselves. It's good for some and bad for others.

The most disturbing part of the new research is on the brain multitasking during driving. If you are driving your car and your phone rings, even if you don't answer it (which I'm sure you know better than to even try), your attention is split to a point of making driving mistakes. Just hearing or feeling the phone pulls attention away from the road and any other distractions that might suddenly happen - a child running into the street, a car swerving into your lane, etc.

Limits on screen time are becoming even more crucial as this research comes out. While we didn't do any screen time before 30 months, when we did start they weren't interested. However we did let them watch up to 20 minutes a day for 5 days a week over the Summer. It's too hot to play outside most afternoons, so this seemed like a great solution. Since I keep this blog a year behind, I can tell you that was too much for my kids. Now at almost 4, they are finally up to that amount and able to handle it without behavioral problems.
