On Tuesday this week the Guardian wrote an article with the title: “All mapped out? Using satnav ‘switches off’ parts of the brain, study suggests”
This article was reporting on a study that was investigating the processes that the brain uses when mapping our environment and planning routes. The headlines emphasises that when we are receiving instructions our brain turns off many of these processes:
The study found that characteristic brain activity linked to simulating the different possible routes for a journey appears to be entirely absent when a person is following directions rather than independently planning a route.
The brain is quite good at not doing things it doesn’t need to do, but that has consequences.
Having read through the article I thought to myself that this would make a really interesting extension to an article that I had previously written on outsourcing our brain functions.
The basic idea of the post was that we use tools to outsource our brain functions and in so doing we risk reducing our brain function. By not exercising the brain capabilities we find ourselves in the place where we are dependent upon the tools and struggle to function without them. A basic example of this is the ability to do mental maths which, on my own unscientific assessment, is completely missing from the younger generation that has always had a machine to do this arithmetic for them. Another example is the memory of phone numbers which people no longer need to do; if you’ve given me your phone number in the last 5 years I probably don’t know it, I still know numbers prior to that time. This time coincides with increased use of mobile phones and no longer needing to know the number to call someone.
So where is the link to the post that I wrote?
I searched this blog for the post.
I searched Google for the post.
I searched my Evernote for this post.
I couldn’t find the post.
Without one of these tools telling me where this post is I’m stuck. Having outsourced that part of my memory I’m completely dependent upon them.
The irony wasn’t lost on me.
