You obviously knows quite a lot of how the brain process information and how it decides and act. How is this though related to the "level of consciousness", or "focus", we feel when acting or deciding? Certainly we are less focused when performing reflex-like routine tasks such as open a drawer than having a live conversation or debate.
If you were asking me, well this was indeed my specialist subject. And the answers are complicated, multilayered. So I could only gloss them here.
A first step is to separate the socially-constructed aspects of human psychology from the neurobiological.
So this is where I would cite social constructionism, or even better, go back to Vygotsky's research on human self-regulation. The Russians, with their Marxist orientation, had no trouble getting the social nature of choice (whereas anglo-saxon treats social factors as the anti-Christ).
Anyway, there is much to be said about how we are trained from childhood to introspect and so be able to actively negotiate our actions - make choices that "consciously" balance the individual need to be competitive/constructive and the social need for co-operation/constraint.
This the great irony. Everyone (anglo-saxon) agonises about their personal freedom. But it is that agonising about having to think everything through at the individual level which is a socially-evolved trait. It underpins the Western expansionist mindset. It kicked us out of the old peasant/feudal equilibrium and set us on the entropically powerlaw - ultimately doomed - course of technologic over-drive.
What's that coming round the corner on the wrong side of the road? Whoops, peak oil.
Anyway, there is the social angle as to why we get into the habit of thinking so much about our individual actions weighed against a social context. "Primitive" cultures just encourage individuals to act on a stable customary basis.
Then there is the neurobiology - which here becomes the question of how well can you actually control your own actions? The time slippage between fast, reflexive, learnt, automatic, habitual, instinctive reponses and thoughtful, attended, deliberated responses is an issue. Who should get the credit when you make lightning decisions in tennis? And who should get the blame when you do something dumb and habitual through "inattention"?
Anglo-saxon society does not care to make fine distinctions. You take the rap either way. The French recognise crimes of passion for example. There is some excuse for the heat of the moment. But mostly it is all about "you". Society can get by without you really having to understand the way you truly work. Which gets you back to the socially-constructed nature of self. You only get to see what suits society - unless you really make an effort and learn the science.
Most people operate not at the level of determined automatons (the computationist's nightmare). But they really are socio-matons. What they are deep inside is just a meme framework which evolved culturally and gets downloaded into every kid through the institutions of a culture.
Nothing bad in this of course. It is the way systems work. The whole has to be able to shape its parts to persist (as it needs exactly those parts to create it as a whole).
But it makes a nonsense of a widespread belief in the specialness of human individuality and self-awareness.
Words like altrusism are part of this. The Western trick has been to externalise moral imperatives (ie: socially valuable memes) as abstract concepts to which individuals are taught to aspire.
You suddenly have this bunch of stuff "deep inside" that you want to express, ideals you want to live up to. A very clever and effective trick that has evolved to shape individual human behaviour.
Many people are dimly aware of how much of all that they do is a social game. And it conflicts them because "it should be coming from inside, but it seems to be coming from outside". And also the concern you mention of "I should be attentively in charge, but so often my too-quick habits catch me out."
However try to think about the situation more carefully and you are having to swim against social constraint. Western society will keep telling you, no thanks son, we prefer you to be our socio-maton. Altruism is an internal quality which you must discover in yourself, not a social constraint that arose for co-operative purposes. And you can't get away with blaming your too-quick reflexes, your murky basement unconscious. Society holds you totally liable for your goodness and badness.
You may think this unfair - oh wait, we haven't loaded you with that capacity to even consider the question. You could do a psychology masters and still not learn it, that's how successfully the truth has been suppressed.
And if you do stumble upon the truth, there are plenty of thought police in the world - the joedogs - who will jump all over you angrily. Society only wants you to have the level of self-awareness that serves its global needs.
