mind-wandering

Blinded by the light

It has become a habit during our summer vacation to read the novels short-listed for Bailey’s Women’s Prize for Fiction.  Unusually this year, we were not only unanimous in our choice of the best novel but we also agreed with the judges and selected the ‘The Power‘ by Naomi Alderman.  In another of the books, Do Not Say We Have Nothing by Madeleine Thien, a Chinese composer called Sparrow thinks ‘about the quality of sunshine, that is, how daylight wipes away the stars and planets, making them invisible to human eyes, might daylight be a form of blindness? Could it be that sound was also be a form of deafness? If so, what was silence?’.  I felt some resonance between these thoughts and John Hull’s writings on blindness and my earlier blog posting on ‘Listening with your eyes shut‘ [on May 31st, 2017].  In our everyday life, we are bombarded with sounds from people living around us, from traffic and from devices in our homes and places of work.  We rarely experience silence; however, when we do, perhaps on holiday staying in a remote rural location, then a whole new set of sounds becomes apparent: waves breaking on the shore in the distance, the field mouse rooting around under the floorboards, or the noises of cattle enjoying the lush grass in the field next door.  Okay, so you have to be in the right place to hear these sounds of nature but you also need silence otherwise you are deaf to them, as Sparrow suggests.

The same is true for knowledge and understanding because our minds have finite capacity [see my post entitled ‘Silence is golden‘ on January 14th, 2014].  When you are bombarded with information and data it is easy to become overwhelmed and unable to structure the information in way that makes it useful or meaningful.  In our connected society, information has become like white noise, or daylight obscuring the stars and planets.  Information is blinding us to knowledge and understanding.  We need to aggressively filter the information flow in order to gain insight and knowledge.  We should switch off the digital devices, which bombard us with information constantly, to leave our minds free for conceptual and creative thinking because that’s one of the few tasks in which we can outperform the smartest machine [see my post entitled ‘Smart machines‘ on February 26th, 2014].

In a similar vein see: ‘Ideas from a balanced mind‘ on August 24th, 2016 and ‘Thinking out-of-the-skull‘ on March 18th, 2015.

In digital detox

I am on vacation so I am re-posting something I wrote around this time last year which I still think is relevant.

It’s official – half of us are addicted to our internet-connected devices and a third of us have attempted to kick the addiction.  A recent study by the UK’s communication regulator, OFCOM found that 59% of internet users considered themselves ‘hooked’ and spending the equivalent of more than a day a week on-line.   They also reported that one in three internet users have attempted a ‘digital detox’ with a third saying they felt more productive afterwards, while slightly more that a quarter found it liberating and another quarter said they enjoyed life more.  So, switch off all of your devices, take a deep vacation, do some off-line reading (see my post entitled ‘Reading offline‘ on March 19th, 2014), slow down and breathe your own air (see my post entitled ‘Slow down, breathe your own air‘ on December 23rd, 2015).  Now, you won’t find many blogs advising you to stop reading them!

Health warning: OFCOM also found that 16% of ‘digital detoxers’ experienced FOMO (Fear Of Missing Out’ (‘FOMO’), 15% felt lost and 14% ‘cut-off’.

Technology causes deflation

Technology enables us to do more in a period of time.  A classic example is the washing-machine that requires you to do little more than load your dirty clothes and switch it on rather than laboriously wash, scrub and rinse each item repeatedly.  It costs less time to do the same thing and so we experience time-deflation.  It’s the same as with money: if you can buy two hamburgers today for the price of one yesterday then there has been some deflation.  In these circumstances, it becomes less important to have a large income because the necessities of life have reduced in price, and so you could work less hard, start saving more (but for what?) or buy some of life’s luxuries.  However, the analogy between time and money breaks down at this point, because you can’t reduce your supply of time or save it, you have to spend it.  But advancing technology means nearly everything costs less time and so it gets harder and harder to spend your alloted time.  Many of us react by trying to do more and more diverse activities, and often simultaneously, with the result that we over-compensate for time-deflation and become bankrupt, or burnt out wrecks.

We can cheat technology’s deflating effect by pursuing activities that involve no time-saving technology such as walking, reading, thinking and spending time with our loved ones.  In the last case, the clue is in the phraseology!

BTW – I will be on deep vacation by the time you read this post. Amongst other things, I will be curing my tsundoko by reading the books I bought in Camden Lock Books earlier in the summer [see my post entitled ‘Tsundoko‘ on May 24th 2017].

Walking through exams

As a student, in the run up to exams, I used to enjoy going out walking in the hills on my own.  This approach to exam preparation probably surprised my fellow students.  While other walkers that I came across probably thought I was mad because, in an age before mobile phones, they would see me talking to myself; because, as I walked, I was reciting material that I needed to learn for the next exam.  This technique worked for me but I have hesitated to recommend such behaviour to my students.  Now, I’ve discovered that psychologists have found that cognitive performance is improved in young adults while walking at a comfortable, relaxed speed.  This is probably connected to the neurogenesis that I wrote about in my post entitled ‘Gone walking’ on April 19th, 2017.

So, as the examination season is underway in many universities, I thought I should pass on my rather eccentric approach to exam revision.  No doubt, I’ll discover that I wasn’t so eccentric after all but none of us dared share such an unconventional approach to exam preparation.

Gone walking

Background and lock-screen pictures have become a feature of modern life.  Your computer and mobile device were probably delivered with some pre-loaded scenes from nature and some of us personalize our devices by up-loading photographs taken on holiday or a recent excursion into the countryside.  Perhaps, we do this intuitively, because recent research has shown that immersion in nature, even at the superficial level of viewing a picture can improve brain function.  Brisk walking stimulates the production of new neurons and, when you do it in an environment enriched with natural stimuli, the connectivity and stability of connectivity between neurons is increased.  For those us whose biological systems are in terminal decline, the opportunity to retard this decline by walking in the wild is too good to miss.  I have gone to the English Lake District to produce and connect some more neurons.  I’ll be back next week – feeling hopefully creative and empowered, as well as, probably rather damp but what else can be expected from northern England in April!

For those of you who want to immerse themselves vicariously in the damp natural environment of England in the rain could read ‘Rain: Four Walks in English Weather‘ by Melissa Harrison.
