“Thoughts are the
shadows of our feelings - always darker, emptier and simpler.”
Nietzsche, The Joyful
Science
It
was 1961 and in the research department of Stanford university, psychologists
looked on as a young boy pounded a large inflatable doll with a hammer. In his
defence, he had just observed an adult doing the same thing - what the
observers found notable was the similarity between his actions and those of the
'model'.
Bandura's
social learning theory proposed something that may seem obvious to us today -
that people could learn things simply by watching other people. Whilst this may
appear to be common sense now it is worth remembering that the prevailing
theory - behaviourism - proposed only two mechanisms of learning: reinforcement
(e.g. punishment or reward) and association (as with Pavlov's dog).
For
sure, we share learning mechanisms with animals - you need only watch
'Supernanny' to see these principles in action. And chickens have been shown to
learn by observation - so this is not a uniquely human trait. What is unusual
about humans is the degree to which their learning mechanisms are intertwined
with their social mechanisms.
Take
mirror neurons for example. Mirror neurons play a fascinating role in our
relationships with others- merely observing another person causes our brain to
mirror their brain state to some degree: when we watch them raise an arm, part
of our brain responds as if we had raised our own arm. When we observe another
person in pain, our brains respond as if we, ourselves, were in pain. Our inter-connectivity
is 'hard wired'.
But
this is really only the tip of the iceberg: our world is experienced in social
terms: when we lose status the effect on the brain is similar to actual
physical pain. When we feel we have gained status (for example when our post is
'liked' on Facebook) our brain releases the same chemicals as it does when we are hugged.
Our
world is social, the things we experience have a social significance interpreted
directly by the brain. We go to school to learn about relationships, roles,
self and self-defence - via the pretext of formal learning. The dramas play out
as we sit through our lessons. We see ourselves first through the eyes of
others, building our self-image through their responses to us, though our
social reflection.
The
events that take place around us - even so minor an event as a move on a
chessboard - take on significance in this context. Our massively parallel brain
learns to 'see' the world in terms of its affective significances and
affordances - what things are threatening, rewarding - bring status and
approbation or ignominy and defeat. Without being consciously aware of it, our
learning mechanisms build this web of emotional associations around everything
we experience, so that our experiences and their affective significance are
inextricable.
This
'affective metadata' is how we encode our lives, and how we process our
thoughts - only affective associations can allow us to understand 'I wander,
lonely as a cloud'. Whilst a deer may instinctively sense a threatening
situation, our reactions are vastly more subtle - though the diference is
quantitative not qualitative.
What
we refer to as 'formal learning' is an effort by the prefrontal cortex (or
'system 2') to exert influence over this learning mechanism. It doesn't work
terribly well. Try as I might, I struggle to remember an important phone
number. I repeat the number over and over, each time reminding myself how
important it is. I would probably do best to imagine myself being torn apart by
wild animals if I forget the number. But the brain is not designed to remember
such things, and our conscious mind exerts limited influence.
Our
uniquely Cartesian error has been to misunderstand ourselves, to attribute to
rationality and the computational model of the mind more significance than it
warrants. We do not 'store information'. Our decision-making process is rarely
deductive. We are creatures that store and compare the subtle webs of
association developed by our affective systems. It turns out that thoughts
really are the shadows of our feelings – and though it is hard to imagine, it
is our feelings not our thoughts that are complex.
Hi Nick,
ReplyDeleteI've heard you speak a couple of times (the first time I didn't stay past the banana eating contest). The second time though I did stay, and enjoyed hearing you speak about affective context. And today, while searching around for more information about it (while preparing for a workshop I'm to give on storytelling) I found this post. Thanks for your thoughts.
