One of the clearest manifestations of my dyslexia when I was younger and something common to many dyslexics was the phenomenon of 'flipping' certain written letters, like the letters , p d b q in my brain. The 'flipping' however was always on the vertical axis and never the horizontal axis. Thus I would have trouble with differentiating between a
q and p
or
d and b
Yet I never had any trouble with flipping on the horizontal access. Never any confusion between
q and d
why ? why only on one axis and not the other ? Maybe it is just the 'horizontal' nature of how text is written but I do not think that is it. Even if I were to write top to bottom rather than left to right I think the flipping still happens in the same way.
Another manifestation of my dyslexia and again something that is common to many dyslexics is struggling with 'left' and 'right' and which is which. Yet never any problems with 'up' and 'down'. Why ?
So on to my 'musing'. None of this is anything I have a firm grip on yet in my head but I have some 'feelings' or 'theories' or musings.
There is, I am starting to suspect, a difference between 'left and right' vs 'up and down' that relates to the arbitrariness of one pair vs the other. Not the arbitrariness of the 'labels', the words we use. An arbitrariness of the actual concepts those words represent. It seems to me that concepts like 'higher' and 'lower' have a connection to the physical structure of the universe in a way that the concept of 'leftness' and 'rightness' do not. That the concepts of 'leftness' and 'rightness' are essentialy arbitrary in a way the concepts of 'highness' and 'lowness' are not.
A higher pitched musical note for example relates to the the physical sound waves and the 'highness' of those waves when visually represented vs a 'low' note. There is as far as I can tell a connection between the concept of 'highness' and 'lowness' and the actual universe itself. You can not produce a high pitched note that does not have a physical 'highness' in the wave that produces that note.
I am not sure the concepts of 'leftness' and 'rightness' has this same connection to the physicality of the universe itself that 'highness' and 'lowness' do ? Could this explain why dyslexics like me struggle with flipping letters on the 'vertical axis' and not the 'horizontal axis' ? Why they struggle with 'left and right' but not with 'high and low' ?
Is there a connection between the concepts of 'leftness' and 'rightness' and the physical universe that I am missing ? In politics we talk of 'the left' and 'the right'. Is it just arbitrary which is which ? Or is there some connection to the physicality of the universe itself ? Is left wing politics described as such rather than 'right' because of the left and right nature of the hemispheres of our brains ? Do the left side of our brains control things like 'empathy' and 'compassion' and the right things like 'calculation' that leads to one end of the political spectrum being associated with the concept 'leftness' rather than 'rightness' ?
I am not sure yet and maybe never will be but I do have a 'hunch' or 'sensation' that there is some kind of difference between these two types of concept pairs (left/right and high/low).
